Abstract:
Riverine territories of the city are a special functional and typological subsystem with constantly emerging environmental problems, experiencing a stable anthropogenic load and requiring the development of its own zoning system. The article presents the systematization of riverine territories with different typological characteristics, and examines the accumulated experience of landscape classification. Riverine territories are also considered as part of the general typology of urban anthropogenic landscapes. Based on a field study of riverine spaces within the boundaries of small towns of the Belgorod region, existing land categories and the most common functional zones are identified. The scientific research is based on a contextual, theoretical, empirical and practical analysis of urban municipal landscapes and riverine territories of the cities of Valuek, Korocha, Alekseyevka, Grayvoron, Shebekino, Biryuch, Novy Oskol. A generalized system of typological zoning for riverine territories of small cities is proposed. As a result of the study, three most common types of territory are identified: natural green areas, natural and anthropogenic landscapes and built-up areas.

Abstract:
Urban riverfront spaces and associated riverine landscapes play important roles in promoting human-river interactions and shaping the regional characteristics of a city. This paper explored the urban riverfront space from the material level of the riverine landscape to a multi-dimensional cognitive level and constructed a theoretical exploration model of the influence of three cognitive dimensions (sensual cognition, intellectual cognition, and rational cognition) on the ‘sense of place’ (SOP) in urban riverfronts. In addition, the measurement scales for different cognitive dimensions were explored and designed. The structural equation model (SEM) was used to analyse 329 valid survey questionnaires in June 2019 in Dujiangyan Yihu Park, China. The analysis of the case study results showed that the overall theoretical model had a good model fit. The sensual cognition, intellectual cognition, and rational cognition all had a significant influence on the SOP in the riverfront park, of which the intellectual cognition had the most significant influence. Strengthening the creation of a riverine landscape for intellectual cognition is expected to enhance the SOP in riverfront spaces more effectively and achieve more enriched interactions between people and rivers.

Abstract:
Abstract A river is a highly complex structure and the constituent of landscape and catchment basin from which it drains water. In the holistic concept, a river is defined in mutual interactions with its surroundings as a spatial system - the riverine landscape. As a product of fluvial processes, the riverine landscape has a regular spatial hierarchical structure, which is determined by the structure of its morphology, substrate, biota, land cover and socioeconomic structures. The aim of this paper is to verify the river landscape hierarchical classification and to identify the so-called higher taxa - zones and segments in the Smrečianka valley. The main data sources were hydrological maps at 1:50 000, topographic maps at 1:10 000 and 1:25 000, GIS database levels, geological maps at 1:50 000, and the boundaries were specified by a field survey

Abstract:
Located in the centre of the Mekong Delta (MD), Can Tho City (CTC), with a development history of more than three centuries, has affirmed its strategic position as an interregional centre. The city on Hau river is blessed by nature with the identity of a delta landscape associated with riverine dynamics. First, this article presents the development history of CTC, and the correlation between its urbanization history and the existing characteristics of the urban landscape. Then, this study further analyses challenges in urban development, assessing existing water infrastructure and opportunities of current urban and rural landscapes. Finally, urban landscape design strategies have been discussed to suggest improved resilience of the city with flood management in the context of climate change.

Abstract:
Abstract. Drainages reorganise in landscapes under diverse conditions and process dynamics that impact biotic distributions and evolution. We first investigated the relative control that Earth surface process parameters have on divide migration and stream capture in scenarios of base-level fall and heterogeneous uplift. A model built with the Landlab toolkit was run 51 200 times in sensitivity analyses that used globally observed values. Large-scale drainage reorganisation occurred only in the model runs within a limited combination of parameters and conditions. Uplift rate, rock erodibility, and the magnitude of perturbation (base-level fall or fault displacement) had the greatest influence on drainage reorganisation. The relative magnitudes of perturbation and topographic relief limited landscape susceptibility to reorganisation. Stream captures occurred more often when the channel head distance to divide was low. Stream topology set by initial conditions strongly affected capture occurrence when the imposed uplift was spatially heterogeneous. We also integrated simulations of geomorphic and biologic processes to investigate relationships among topographic relief, drainage reorganisation, and riverine species diversification in the two scenarios described above. We used a new Landlab component called SpeciesEvolver that models species at landscape scale following macroevolutionary process rules. More frequent stream capture and less frequent stream network disappearance due to divide migration increased speciation and decreased extinction, respectively, especially in the heterogeneous uplift scenario in which final species diversity was often greater than the base-level fall scenario. Under both scenarios, the landscape conditions that led to drainage reorganisation also controlled diversification. Across the model trials, the climatic or tectonic perturbation was more likely in low-relief landscapes to drive more extensive drainage reorganisation that in turn increased the diversity of riverine species lineages, especially for the species that evolved more rapidly. This model result supports recent research on natural systems that implicates drainage reorganisation as a mechanism of riverine species diversification in lowland basins. Future research applications of SpeciesEvolver software can incorporate complex climatic and tectonic forcings as they relate to macroevolution and surface processes, as well as region- and taxon-specific organisms based in rivers and those on continents at large.

Abstract:
Effective conservation, particularly of threatened species, requires an understanding of both abiotic and biotic drivers of distribution. In the case of one of Africa’s most endangered mammals, the riverine rabbit Bunolagus monticularis, only environmental covariates of presence have been used to provide coarse predictions of their distribution. Two potential competitors, namely scrub hare Lepus saxatilis and cape hare L. capensis, have significant (>90%) range overlap with the riverine rabbit, yet little is known about how these species interact. We used multi-species occupancy models, which model co-occurrence as a function of environmental variables, to assess the spatial response of riverine rabbits to both species of hare in Sanbona Wildlife Reserve, South Africa. We also examined temporal overlap between riverine rabbits and hares. Camera trapping data were collected from 150 camera traps distributed in clusters of 5 cameras at 30 independent sites, covering 223.24 km2. Contrary to prior studies, we found that riverine rabbits were not restricted to riparian habitat, and that their occurrence was conditional on hare absence and was negatively affected by terrain ruggedness. Whilst hare occurrence was independent of terrain ruggedness, it was negatively affected by rabbit presence. Activity patterns revealed high temporal overlap between hares and rabbits (Δ = 0.828, CI = 0.745-0.940); however, neither species co-occurred at any given site. Our results suggest that conservation management has greatly underestimated the importance of competition with other lagomorphs in understanding riverine rabbit occurrence.

Abstract:
Increasing anthropogenic nitrogen (N) emission via different pathways has shown prominent impact on aquatic ecosystems for decades, but the effects of interaction among climate-, landscape- and human-associated variables on riverine DIN (dissolved inorganic nitrogen, mainly NO3− and NH4+) export are unclear. In this study, the data of 43 watersheds with a wide range of climate-, landscape- and human-associated gradients across Taiwan were evaluated with partial redundancy analysis (pRDA) to examine their interactive controls on riverine DIN export. Results show that the annual riverine DIN export in Taiwan is approximately 3100 kg-N km−2 yr−1, spanning from 230 kg-N km−2 yr−1 in less disturbed watersheds (eastern and central Taiwan) to 10,000 kg-N km−2 yr−1 in watersheds with intensive human intervention (southwestern and northern Taiwan). NO3− is generally the single dominant form of DIN, while NH4+ renders significance in disturbed watersheds. Nearly all environmental variables display a positive correlation with DIN export, except for landscape setting variables (e.g., slope, area, channel length), which show a negative relationship. In terms of seasonal pattern, climate and human-landscape variables are related to NO3− export independently in the wet season, yet in the dry season climate-human variables jointly dominate NO3− export. Meanwhile, human-landscape (LH) variables (λ1 of LH > 0.60) control NH4+ exports in both seasons, and human-associated (H) variables (λ1 of H = 0.13) have a minor effect on NH4+ exports in dry season. Precisely, the contribution of controlling variables on DIN export vary with species and seasons, indicating water quality management could be time-dependent, which should be taken into consideration for designing mitigation strategies.

Abstract:
The article is focused on studies of domestic and foreign scientists concerning the aesthetic properties of landscapes. Different methodological approaches of analysis and description of the visual quality of landscapes are presented. The world experience in the application of methods to assess the landscape attractiveness of territories when arranging of recreational zones was studied. The analysis of different types of landscapes, their aesthetic advantages and disadvantages, as well as characteristics from the point of view of the arrangements of recreational areas was carried out. The relation between natural features of the area, its aesthetic parameters and the demand degree among vacationers was revealed. The features of the natural framework of the Belgorod region were determined; characteristic of regional landscape features, affecting the emotional perception of landscapes (chalk outcrops, wetlands of riverine lands, etc.) were identified. The assessment of the aesthetic attractiveness of landscapes is carried out using the territories of the Valuysky municipal district as an example. The localization of the areas with the greatest aesthetic attractiveness was determined and the promising territories for the development of recreational zones were identified. The compositional structure of the gully-like landscape was analyzed as one of the characteristic features for this region as a whole. Recommendations on the application of the assessment method for aesthetic of landscape attractiveness, taking into account regional characteristics the Belgorod region as an example were proposed.

<p><strong>Abstract.</strong> The Vltava River and its surroundings had many different faces and functions in the past centuries. The Vltava is the longest river running through the heart of Bohemia, probably the most famous and popular river in the Czech Republic, one of the national symbols, important trade and transport route in the past, river with beautiful landscape favourite by poets, travellers, and tourists, place where the biggest dam reservoir system in the Czech Republic was built, popular recreational area in the present and many more. Therefore, many different documents are dealing with the Vltava River and its riverine landscape.</p><p> The main objective of the project supported by the Ministry of Culture of the Czech Republic is to create comprehensive information system about the Vltava River aggregating and incorporating various historical and modern documents and data. This system will allow maintaining and documenting a wealth of information about the history of the Vltava River, including immovable and movable cultural heritage using new technologies. The project is focused on the upper three quarters of the Vltava River from its springs to confluence with the Berounka River close to Prague in the period from mid 18th century up to the present day. Riverine landscape along the Vltava underwent an intensive transformation in many aspects. Firstly, the cultural landscape with mostly minor settlement combined with appreciated but even feared wild natural narrow valleys has changed intensively along with a construction of the dam cascade especially in the middle part of the river in the second half of the 20th century. Small but widespread settlements, transport function of the river and wild nature were replaced by dams producing electric energy and retaining extensive water reservoirs providing water supply and protection from frequent inundations and last but not least being very popular for recreation. Unfortunately, many houses, water mills, chapels, churches, picturesque natural places, etc. have been flooded. The former face of the Vltava riverine landscape is preserved only in various archival documents and their online presentation is the main project goal.</p><p> There are large volumes of miscellaneous historical and modern data sources dealing with the Vltava river which are being used in the project. Extensive research of various public and institutional archives is currently still being carried out. Some resources such as old photographs and postcards are found also in private collections. First of all, there are various works from old cadastral maps, old river maps with cross sections, longitudinal profiles of the river, old site plans and interesting building plans, State Derived Map and aerial photographs from 1950s, site and constructional plans of dams to the up to date cadastral map, orthophotos and DTM. The Imperial Imprints of the Stable Cadastre (scale 1&amp;thinsp;:&amp;thinsp;2&amp;thinsp;880) from the years 1826–1843 rank among the most valuable and very useful. Due to their geometric precision and visual attractiveness, these maps are suitable for vectorization, and form an excellent base layer for the web mapping application and 3D visualization. Another very important map is the State Derived Map (scale 1&amp;thinsp;:&amp;thinsp;5&amp;thinsp;000; its first issue) from the early 1950s containing planimetry as well as altimetry. It shows situation of area just before the dam reservoirs cascade construction was started hence it allows reconstruction of former Vltava valley. Maps and plans are complemented by old photographs, postcards, iconography and also text sources.</p><p> All data sources described above have to be carefully processed before their incorporation into the information system and subsequent 2D- or 3D- applications could be designed. Speaking in particular about maps and plans, they have to be digitised, georeferenced and selected map content is vectorised. The majority of data sources are obtained in the analogue paper form, thereby a high resolution scanning has to be done to acquire digital copies of requested maps and plans. Then the scanned data is georeferenced employing suitable global or local transformations depending on the type of map. Carefully selected map content is vectorised and the database of significant features (buildings or objects of cultural, social, production and water management importance) with important attributes is being filled up. Every feature has its location, at least approximately if precise position is unknown. Also the old photographs and postcards are geolocated to be incorporated into the information system.</p><p> 2D web mapping application (Figure 1) has been created based on processed data and it is being updated. It presents and compares various layers (georeferenced maps and plans, vectorised data model, objects of interest, etc.). The application allows overlaying of various raster and vector layers from different times using the swipe tool. Objects of interest and photographs are represented by points, where each point leads to a popup with more information.</p><p> Online 3D visualisation is effective and popular way of geographical data presentation thus besides the 2D also 3D application may bring a new perspective to former Vltava landscape. The Vltava River valley, often narrow and deep, is perfect for the 3D presentation, especially if it is completed by other objects or phenomena (e.g. extinct settlements, important buildings, historical or potential floods). Precise 3D modelling of important structures in CAD software is a common but time-consuming process. Therefore, it is not possible to model the whole extinct settlements in 3D and thus procedural modelling is applied instead. It allows to visualise a simplified reconstructive model of flooded villages in the entire area of interest even in various periods of time.</p><p> The mission of the project is, in particular, to document information on the changes of the Vltava riverine landscape within the last three centuries in the context of various events, as well as to make it subsequently available to the general public. Thus, it might act as a transfer of historical science into education through modern cartographic methods. The project itself is actually in its first phase and the activities proceed continuously.</p>

Abstract:
The results of research on the content and distribution of trace elements in alluvial soils of various elements of the floodplain landscape, and their relationship with fertility indicators are presented. It has been found that the maximum concentrations of most trace elements (Ni, Zn, Mn, Cr, Co, Mo, As) are characteristic of the alluvial overhanging-marsh heavy-coal pristine subsystem of the floodplain landscape. In the riverine and perish subsystems of the floodplain landscape in individual layers of the corresponding soils, an excess of clark was found: in the alluvial sour acid layered primitive shortened sandy loam Cu by 1.5; Zn in 1.1; Cd 9.2 times, in alluvial chilli-marsh heavy-coal Cu 1.05; Zn in 1.4; Mn in 1.01; Cr in 1,2; Cd 3.2 times. For the riverine and perch subsystems, the excess of Cu, Mn and Cr was observed in the soil layer 0-5 cm, the remaining exceedances are characteristic of deeper layers. Decreasing rows of trace elements in alluvial soils have a similar structure. The microelements in question, in the soils of the floodplain landscape of the Iput River, in terms of clark concentration, belong to the group of dispersing. There is no significant correlation between micronutrient content and fertility of the alluvial soils under consideration.

Abstract:
Loss of forest cover, rise in human populations and fragmentation of habitats leads to decline in biodiversity and extinction of large mammals globally. Elephants, being the largest of terrestrial mammals, symbolize global conservation programs and co-occur with humans within multiple-use landscapes of Asia and Africa. Within such shared landscapes, poaching, habitat loss and extent of human–elephant conflicts (HEC) affect survival and conservation of elephants. HEC are severe in South Asia with increasing attacks on humans, crop depredation and property damage. Such incidents reduce societal tolerance towards elephants and increase the risk of retaliation by local communities. We analyzed a 2-year dataset on crop depredation by Asian elephants (N = 380) events in North Bengal (eastern India). We also explored the effect of landscape, anthropogenic factors (area of forest, agriculture, distance to protected area, area of human settlements, riverine patches and human density) on the spatial occurrence of such incidents.Crop depredation showed a distinct nocturnal pattern (22.00–06:00) and majority of the incidents were recorded in the monsoon and post-monsoon seasons. Results of our spatial analysis suggest that crop depredation increased with an increase in the area of forest patches, agriculture, presence of riverine patches and human density. Probability of crop depredation further increased with decreasing distance from protected areas. Villages within 1.5 km of a forest patch were most affected. Crop raiding incidents suggest a deviation from the “high-risk high-gain male biased” foraging behavior and involved proportionately more mixed groups (57%) than lone bulls (43%). Demographic data suggest that mixed groups comprised an average of 23 individuals with adult and sub adult females, bulls and calves. Crop depredation and fatal elephant attacks on humans were spatially clustered with eastern, central and western parts of North Bengal identified as hotspots of HEC. Our results will help to prioritize mitigation measures such as prohibition of alcohol production within villages, improving condition of riverine patches, changing crop composition, fencing agriculture fields, implement early warning systems around protected areas and training local people on how to prevent conflicts.

Abstract:
Abstract Historical gardens established around manors form an integral part of the European cultural landscape. Recent studies have revealed that manor gardens may serve as local hotspots of biodiversity and provide cultural ecosystem services within urban areas but also in rural landscapes. As a consequence of dramatic land-use changes in recent centuries, followed by a significant loss and degradation of natural habitats, manor gardens often serve as refugia for organisms within the cultural landscape. To compare the proportion of natural habitats in manor gardens with the surrounding landscape, intensively used and semi-natural landscapes were distinguished within a grid using Coordinated Information on the Environment (CORINE) land cover data for the Czech Republic. One hundred manor gardens were randomly selected, followed by a grid overlay of data from the Natura 2000 mapping system. Proportions of natural habitats were calculated for each garden in relation to the surrounding landscape. The results confirmed that manor gardens, compared with the surrounding landscape, play an important role in the conservation of natural habitats, especially in areas with a high level of human impact. For the gardens studied, occurrences of the following natural habitat types from the Natura 2000 system were recorded: forests (25.4 % of the garden area), secondary grasslands (4.4 %), streams and water bodies (1.6 %) and wetlands and riverine vegetation (0.5 %). The proportion of natural habitats within the gardens compared to the surrounding areas was significantly higher in the majority of cases.

Abstract:
Abstract. Increases in nitrogen (N) availability and mobility resulting from anthropogenic activities have substantially altered the N cycle, both locally and globally. Taiwan characterized by the subtropical montane landscape with abundant rainfall, downwind of the most rapidly industrializing eastern coast of China, can be a demonstration site for extremely high N input and riverine DIN (dissolved inorganic N) export. We used 49 watersheds with similar climatic and landscape settings but classified into low, moderate, and highly disturbed categories based on population density to illustrate their differences in nitrogen inputs (through atmospheric N deposition, synthetic fertilizers, and human emission) and DIN export ratios. Our results showed that the island-wide average riverine DIN export is ∼ 3800 kg N km−2 yr−1, approximately 18 times the global average. The average riverine DIN export ratios are 0.30–0.51, which are much higher than the averages of 0.20–0.25 of large rivers around the world, indicating excessive N input relative to ecosystem demand or retention capacity. The low disturbed watersheds have a high N retention capacity and DIN export ratios of 0.06–0.18 in spite of the high N input (∼ 4900 kg N km−2 yr−1). The high retention capacity is likely due to effective uptake by secondary forests in the watersheds. The moderately disturbed watersheds show a linear increase in DIN export with increases in total N inputs and mean DIN export ratios of 0.20 to 0.31. The main difference in land use between low and moderately disturbed watersheds is the greater proportion of agricultural land cover in the moderately disturbed watersheds. Thus, their greater DIN export could be attributed to N fertilizers used in the agricultural lands. The greater export ratios also imply that agricultural lands have a lower proportional N retention capacity and that reforestation could be an effective land management practice to reduce riverine DIN export. The export ratios of the highly disturbed watersheds are very high, 0.42–0.53, suggesting that much of the N input is transported downstream directly, and urges the need to increase the proportion of households connected to a sewage system and improve the effectiveness of wastewater treatment systems. The increases in the riverine DIN export ratio along the gradient of human disturbance also suggest a gradient in N saturation in subtropical Taiwan. Our results help to improve our understanding of factors controlling riverine DIN export and provide empirical evidence that calls for sound N emission/pollution control measures.

Full text
Abstract:
The Midwest has large riverine exports of nitrogen (N), with the largest flux per unit area to the Mississippi River system coming from Iowa and Illinois. We used historic and current data to estimate N inputs, outputs, and transformations for Illinois where human activity (principally agriculture and associated landscape drainage) have had a dominant impact. Presently, ~800,000 Mg of N is added each year as fertilizer and another 420,000 Mg is biologically fixed, primarily by soybean (Glycine max L. Merr.). These annual inputs are greater than exports in grain, which results in surplus N throughout the landscape. Rivers within the state export approximately 50% of this surplus N, mostly as nitrate, and the remainder appears to be denitrified or temporarily incorporated into the soil organic matter pool. The magnitude of N losses for 1880, 1910, 1950, and 1990 are compared. Initial cultivation of the prairies released large quantities of N (~500,000 Mg N year�1), and resulted in riverine N transport during the late 19th century that appears to have been on the same order of magnitude as contemporary N losses. Riverine flux was estimated to have been at a minimum in about 1950, due to diminished net mineralization and low fertilizer inputs. Residual fertilizer N from corn (Zea mays L.), biological N fixed by soybean, short-circuiting of soil water through artificial drainage, and decreased cropping-system diversity appear to be the primary sources for current N export.

Abstract:
The megadiverse haplochromine cichlid radiations of the East African lakes, famous examples of explosive speciation and adaptive radiation, are according to recent studies, introgressed by different riverine lineages. This study is based on the first comprehensive mitochondrial and nuclear DNA dataset from extensive sampling of riverine haplochromine cichlids. It includes species from the lower River Congo and Angolan (River Kwanza) drainages. Reconstruction of phylogenetic hypotheses revealed the paradox of clearly discordant phylogenetic signals. Closely related mtDNA haplotypes are distributed thousands of kilometres apart and across major African watersheds, whereas some neighbouring species carry drastically divergent mtDNA haplotypes. At shallow and deep phylogenetic layers, strong signals of hybridization are attributed to the complex Late Miocene/Early Pliocene palaeohistory of African rivers. Hybridization of multiple lineages across changing watersheds shaped each of the major haplochromine radiations in lakes Tanganyika, Victoria, Malawi and the Kalahari Palaeolakes, as well as a miniature species flock in the Congo basin (River Fwa). On the basis of our results, introgression occurred not only on a spatially restricted scale, but massively over almost the whole range of the haplochromine distribution. This provides an alternative view on the origin and exceptional high diversity of this enigmatic vertebrate group.

Abstract:
At present, the problems of local urban regulation of the riverine territories are becoming increasingly relevant for Russian Federation. The article describes the main issues of organization the local self-government in Russia. The modern foreign experience of local urban regulation of the riverine territories in Sweden, Denmark, Germany, France, Belgium (Walloon region, Flemish region and Brussels-Capital Region), the Netherlands and Poland are studied. Possible options for such regulation are described: governmental organizations, community projects, local development strategies. Strategies are carried out through the formulation and development of ideas at the local level and the filing an application in search of cooperation with the municipality and private business. Options for local participation in the development of riverine areas are considered. An example is given of the “Leader” method based on cooperation of the state, public, private and non-profit sectors, which form a local development group, a local action group for the development of territories along the river Göta älv in Sweden. Municipal strategy of landscape interests in the city and around the city of Aalborg (Denmark) is analyzed. A brief description is given to the Weser River Basin Community (The Flussgebietsgemeinschaft Weser (FGG Weser)) in Germany. Examples of existing inter-municipal non-governmental projects in Poland and activities aimed at unlocking the tourist and cultural potential of riverine areas of Vistula river are studied. Conclusions on the possibility of forming a single inter-municipal authority that will coordinate the development of the riverine territories are drawn.

Abstract:
Understanding movement and habitat requirements of endangered species is critical to conservation management. We evaluate fine-scale acoustic telemetry to study breeding-related movement and habitat use of the endangered Mary River cod Maccullochella mariensis in a riverine environment and, in relation to key environmental variables, to inform management. Movement activity varied significantly in relation to water temperature and diel period, and spatial occupancy and habitat selection varied substantially in relation to the nesting behaviour of Mary River cod. Important nesting habitat included a large hollow log mid-channel and well-shaded logs and log jams adjacent to the river bank. Extrapolating this information to the general population was inhibited by relatively small sample sizes, due in part to the restricted spatial scale of the hydrophone arrays and longitudinal movements of tagged fish beyond the acoustic range of our array. Notwithstanding this, our results demonstrate that (1) fine-scale acoustic telemetry can quantify complex biological behaviours in riverine environments; (2) Mary River cod require specific environmental stimuli and habitat to support the reproductive cycle; and (3) changing environmental conditions may influence Mary River cod behaviour, and understanding this response is necessary for sustainable management. Findings from this study can inform future applications of this methodology in riverine environments and contribute to the development of management strategies and habitat restoration activities supporting the recovery of Mary River cod populations.

Abstract:
The 280 000 km² Xingu indigenous lands and protected areas (ILPAs) corridor, inhabited by 24 indigenous peoples and about 215 riverine (ribeirinho) families, lies across active agriculture frontiers in some of the historically highest-deforestation regions of the Amazon. Much of the Xingu is anthropogenic landscape, densely inhabited and managed by indigenous populations over the past millennium. Indigenous and riverine peoples' historical management and use of these landscapes have enabled their long-term occupation and ultimately their protection. The corridor vividly demonstrates how ILPAs halt deforestation and why they may account for a large part of the 70 per cent reduction in Amazon deforestation below the 1996–2005 average since 2005. However, ongoing and planned dams, road paving, logging and mining, together with increasing demand for agricultural commodities, continued degradation of upper headwaters outside ILPA borders and climate change impacts may render these gains ephemeral. Local peoples will need new, bottom-up, forms of governance to gain recognition for the high social and biological diversity of these territories in development policy and planning, and finance commensurate with the value of their ecosystem services. Indigenous groups' reports of changing fire and rainfall regimes may themselves evidence climate change impacts, a new and serious threat.

Abstract. This study provides a new approach to estimate both anthropogenic non-point-source and point-source nitrogen (N) inputs to the landscape, and determines their impacts on riverine ammonia–nitrogen (AN) flux, providing a foundation for further exploration of anthropogenic effects on N pollution. Our study site is Huai River basin of China, a water–shed with one of the highest levels of N input in the world. Multi-year average (2003–2010) inputs of N to the watershed are 27 200 ± 1100 kg N km−2 yr−1. Non-point sources comprised about 98 % of total N input, and only 2 % of inputs are directly added to the aquatic ecosystem as point sources. Fertilizer application was the largest non-point source of new N to the Huai River basin (69 % of net anthropogenic N inputs), followed by atmospheric deposition (20 %), N fixation in croplands (7 %), and N content of imported food and feed (2 %). High N inputs showed impacts on riverine AN flux: fertilizer application, point-source N input, and atmospheric N deposition were proved as more direct sources to riverine AN flux. Modes of N delivery and losses associated with biological denitrification in rivers, water consumption, interception by dams may influence the extent of export of riverine AN flux from N sources. Our findings highlight the importance of anthropogenic N inputs from both point sources and non-point sources in heavily polluted watersheds, and provide some implications for AN prediction and management.

Full text
Abstract:
Ecologists long have been aware that there is flux of energy and nutrients from riverine systems to the surrounding terrestrial landscape and vice versa. Riparian ecotones are diverse and ecologically important. Consequently, there is substantial literature examining faunal-mediated transfers of energy and nutrients from rivers into terrestrial food webs. A wide variety of taxa has been shown to utilise riparian resources, from species specialised for existence at the aquatic–terrestrial interface to opportunistic predators and scavengers. Outputs from rivers may be influenced by productivity gradients, channel geometry and the condition of the exchange surface. Until recently, consideration of faunal-transferred, allochthonous inputs has been peripheral to other research questions. The development of general models of inter-habitat transfers, together with advances in technology, has placed questions about the ecological importance of riverine outputs squarely on the research agenda. Researchers now are investigating how aquatic subsidies influence food-web dynamics at landscape scales. However, ecologists continue to largely ignore subsidisation of terrestrial food webs by energy and nutrients from floodwaters in lowland river–floodplain systems. The dearth of information about the benefits of flooding to terrestrial consumers appears to have resulted in underestimation of the gross ecological impacts of river regulation.

Abstract:
SUMMARYThe degradation, alteration and depletion of riparian habitats caused by river regulation are among critical conservation concerns. Aquatic and riparian habitats support not only river-dwelling biota such as macroinvertebrates and fish, but also waterbirds, the top predators in the aquatic food web. Despite the intimate relationships between fish and waterbirds, the two groups are often investigated separately. Using an integrative approach, we examined the effects of dams on fish and scaly-sided merganser (Mergus squamatus), an endangered, iconic riverine species, where the lack of knowledge about habitat preferences greatly hampers long-term conservation efforts. Our analysis quantified three causal links: (1) water depth had direct, comparable, negative effects on both fish and waterbirds, and the path coefficients for fish and birds are –0.31 and –0.46, respectively; (2) river landscape heterogeneity directly and positively affected fish and waterbirds, and the path coefficients for fish and birds are 0.63 and 0.19, respectively; and (3) depth and river landscape also exerted indirect effects on waterbirds through their impacts on fish abundance, and the path coefficients for fish and birds are –0.15 and 0.28, respectively. Our findings could contribute to the rational spatial planning and sustainable operation of dams in that maintaining instream habitat availability and heterogeneity would benefit the whole riverine ecosystem.

Abstract:
Land-use changes over the last century in southern Minnesota have influenced riverine water chemistry. A nested watershed approach was used to examine hydrologic pathways of water movement in this now agriculturally intensive region. From field scale subsurface tile-drains of the Beauford ditch to the respective outlets of the Cobb River and Blue Earth River, more than 125 samples were collected for major dissolved ions and isotopes between March 1994 and June 1996 over a range of climatic conditions that included snowmelt and storm-flows. Results indicate that riverine water chemistry is dominated by subsurface tile-drained row crop agriculture. In the mid-1990s, regional ground water discharge into the Cobb and Blue Earth Rivers comprised less than 10% of the total flow based on ionic mixing calculations. Ammonia, present in manure or as anhydrous, is readily exchanged in the soil. This ion exchange releases increasing ratios of magnesium, sodium and strontium relative to calcium, the dominant cation. Soil thaw and snowmelt recharge influenced March–April tile-drain and ditch water isotopic values. Light δD values increased as spring infiltration-derived water was displaced from the soil zone by heavier summer precipitation. δ15N followed a similar but opposite pattern with relatively heavy March–April tile-drain and ditch values trending to lighter δ15N through the growing season. The future of southern Minnesota riverine water quality is closely linked to the management of the landscape. To improve the riverine environment, land owners and managers will need to address cropping systems, fertilization practices and drainage.

Abstract. This paper reviews the possible functions of robust dikes in the rural riverine areas of the Netherlands. It furthermore reviews and analyses strengths, weaknesses, opportunities, and threats associated with robust, multifunctional flood defense zones in rural riverine zones. The study focused on recent plans and ideas for innovative dike reinforcement at five locations in the Netherlands, supplemented with information obtained in semi-structured interviews with experts and stakeholders. At each of the five locations, suitable robust flood defenses could be identified that would contribute to the envisaged functions and ambitions for the respective areas. Primary strengths of the robust, multifunctional approach were identified as combined uses of limited space, a longer-term focus, and greater safety. The new approach offers opportunities as well, in particular, with regard to tasks, problems, and objectives related to infrastructure, land-use planning, nature and landscape protection, and development. These provide possibilities for co-financing as well.

Abstract:
The metal composition of water and bottom sediments of southern Lake Baikal tributaries was studied and the water migration coefficients for micro- and trace elements were calculated. The map showing the study area divided into zones according to their ability to provide the certain water quality was drawn. The significant differences in mineralization, macro- and trace element composition between Lake Baikal water and tributary waters were found out. It was shown that values of water migration coefficients calculated for macro elements are similar in southern and main tributaries whereas coefficient values calculated for trace elements are quite different. This is due to dissolved matter sources such as rocks and deep ground waters which chemical composition is not typical for landscapes of Lake Baikal basin. The contribution of southern tributaries to macro element composition of lake water is between 7 and 15%, whereas tributaries contribution to trace element composition can hardly be evaluated because of higher element concentrations in riverine waters. The lower trace element concentrations in lake water with respect to riverine one is due to trace element migration in the form of complex organic compounds: long water residence time in lake favors to organic compounds decay by means of microbial- and photo-degradation followed by metal precipitation.

Abstract:
The ongoing debate on the boon or bane of monocultural timber plantations demonstrates the need to develop alternative approaches that achieve forest productivity while conserving biodiversity. We assessed the diversity of tree species in native forests and in Eucalyptus plantations, and evaluated the potential use of native species to enhance plantation management. For this purpose, we established one-hectare permanent plots in nine native forests (riverine and park forests) and nine Eucalyptus plantations in the northwestern part of Uruguay. Forest inventories were carried out on 200 m2 plots and regeneration was assessed along transects in 9 m2 subplots. Riverine forests have the highest Shannon diversity index (2.5) followed by park forests (2.1) and Eucalyptus plantations (1.3). Tree density was high in riverine forests (1913/ha) and plantations (1315/ha), whereas park forests have lower tree density (796/ha). Regeneration density was high in riverine forests (39136/ha) and park forests (7500/ha); however, native species can regenerate in the understory of plantations (727/ha), and this underlines the possibility of developing a mixed species approach to reduce the negative impact of monocultures. Differences in the composition of plant communities were denoted between native forests and plantations, although native forests were similar in composition, even in the presence of exotic species. Native forests harbor specialist species that are absent from plantations, and therefore perform a decisive role in maintaining local biodiversity. Strategies to enhance species diversity and structural diversity within plantations or to establish mixed buffer strips containing native species at the edge of plantations are potential measures to enhance biodiversity and foster the integration of plantations into the local landscape.

Spatial patterns of the exotic riverine knotgrass (Paspalum distichum L.) were examined in Mediterranean river basins in Southwestern Iberia. The major goals of this study were to assess the degree of invasibility of riparian habitats by this species and to determine the influence of environmental factors and human-induced disturbances that this knotgrass has on both the landscape and the habitat scales. The present study demonstrates the ability of knotgrass to invade riparian habitats in Portuguese freshwater ecosystems. However, most of the spatial variation of the knotgrass cover seemed to be driven by local factors, such as fine sediment enrichment and the fragmentation of riparian woods, and by other anthropogenic interferences in relation to both the fluvial system and the surrounding landscape.

Abstract. For more than 30 years, since the end of the 1980s, Russia's urban planning policy has been in a state of reinterpretation. After the collapse of the system of total state control and planning, there was a period of almost uncontrolled point development of cities, focused on obtaining maximum benefits in the short term. This period of urban planning nihilism has also come to an end, but for the final exit from it and the acquisition of a full-fledged strategy for urban planning and social development in Russia, it is necessary to formulate the target parameters of the system. Among these parameters, of course, is the provision of conditions for the reproduction and increase of the main resource of the state – human potential. One of the necessary conditions for achieving this goal is to radically improve the quality of the human environment. A favorable environment is always based on natural and climatic conditions and the landscape of the area, or rather-a competent and rational use of the features of the landscape for the implementation of socially significant functions. One of the most obvious and important functions of the landscape is view – spatial. This article discusses the mechanics of implementing this function and its relationship with other functions of the Landscape as a subsystem of a settlement. Landscape-spatial function of the Landscape belongs to the category of aesthetic functions and is realized through the formation of positive impressions and emotions from the contemplation of beautiful landscape views, the compositional center and the main background of which are natural objects. Positive emotions from the contemplation of natural landscapes can reduce the psycho-emotional stress that occurs in a person under the influence of the architectural, technical and information environment of a modern city. The article also substantiates the high potential of riverine territories for the implementation of view – spatial functions.

Abstract:
Hydrochemistry and sulfur isotope (δ34S–SO42−) of Chishui River watershed in Southwest China were measured to identify the sources of riverine solutes, the potential impact of human activities, water quality, and health risk. The main findings indicated that the HCO3− (2.22 mmol/L) and Ca2+ (1.54 mmol/L) were the major ions, with the cation order of Ca2+ (71 ± 6%) > Mg2+ (21 ± 6%) > Na+ + K+ (8 ± 3%) and the anion sequence of HCO3− (55 ± 9%) > SO42− (41 ± 9%) > Cl− (4 ± 3%). The riverine δ34S–SO42− values fluctuated from −7.79‰ to +22.13‰ (average +4.68‰). Overall, the water samples from Chishui River presented a hydrochemical type of Calcium–Bicarbonate. The stoichiometry and PCA analysis extracted three PCs that explained 79.67% of the total variances. PC 1 with significantly positive loadings of K+, Mg2+, F−, HCO3− and relatively strong loading of Ca2+ revealed the natural sources of rock weathering inputs (mainly carbonate). PC 2 (Na+ and Cl−) was primarily explained as atmospheric contribution, while the human inputs were assuaged by landscape setting and river water mixing processes. The strongest loadings of SO42− and NO3− were found in PC 3, which could be defined as the anthropogenic inputs. The H2SO4–involved weathering processes significantly impacted (facilitated weathering) the concentrations of riverine total ions. Sulfur isotope compositions further indicated that riverine SO42− were mainly controlled by anthropogenic inputs SO42− compared to the sulfide oxidation derived SO42−, and the atmospheric contribution was very limited. The results of risk and water quality assessment demonstrated that Chishui River water was desirable for irrigation and drinking purposes due to low hazard quotient values (<1, ignorable risk), but long–term monitoring is still worthy under the circumstances of global environmental change.
