Abstract (sommario):

The purpose of this study was to investigate streptomycete populations in desert and savanna ecozones in Sudan and to identify species based on 16S rRNA gene sequences. A total of 49 different Streptomyces phenotypes (22 from sites representing the desert and semi-desert ecozone; 27 representing the savanna ecozone) have been included in the study. The isolates were characterized phenotypically and confirmed using 16S rRNA gene sequence analysis. The two ecozones showed both similarities and uniqueness in the types of isolates. The shared species were in cluster 1 (Streptomyces (S.) werraensis), cluster 2 (Streptomyces sp.), cluster 3 (S. griseomycini-like), and cluster 7 (S. rochei). The desert ecozone revealed unique species in cluster 9 (Streptomyces sp.) and cluster 10 (S. griseomycini). Whereas, the savanna ecozone revealed unique species in cluster 4 (Streptomyces sp.), cluster 5 (S. albogriseolus/ S. griseoincarnatus), cluster 6 (S. djakartensis), and cluster 8 (Streptomyces sp.). Streptomycetes are widely distributed in both desert and the savanna ecozones and many of these require full descriptions. Extending knowledge on Streptomyces communities and their dynamics in different ecological zones and their potential antibiotic production is needed.

Abstract (sommario):

Low-flow occurrence and magnitude have been documented for Canada using the National Ecological Framework. The low flow database is composed of the 7-day low flow with 2-year return period (7Q2) values for 453 natural flow hydrometric stations with record lengths of at least 30 years; drainage areas ranged from 10 to 30 000 km2. Occurrence zones corresponding to predominant season for annual low flows are associated with ecozones. The ecozone scale was found to be suitable for regional analysis for several ecozones. For some ecozones there were insufficient data for regional analysis and for others finer resolution is required. Regional regression equations were developed for estimating 7Q2 in terms of area for ecozones containing at least 20 stations. The results of this work will help practitioners to identify the season of low flow occurrence and the appropriate method of analysis, and provide a means of estimating 7Q2 for ungauged sites for some ecozones.

Abstract (sommario):

The present study characterized the spatial patterns of forest fires in 10 fire-dominated ecozones of Canada by using a database of mapped fires ≥200 ha from 1980 to 1999 (n = 5533 fires). Spatial metrics were used individually to compare measures of fire size, shape (eccentricity and complexity), clustering, and geographic orientation among ecozones and were used concurrently in a multivariate analysis. In addition, a set of factors that influence the fire regime at the ecozone level – topography, climate, fuels, and anthropogenic factors – was compared with the metric outputs. We found significant differences in all spatial metrics among ecozones. The multivariate analysis showed that the Montane Cordillera ecozone, which covers most of British Columbia, had the most distinctive fires: its fires were smaller, less complex, and had a more regular distribution. The fire regime descriptors of ecozones were useful to interpret the spatial variation of some spatial metrics, such as fire size, eccentricity, and clustering, but provided little insight into the mechanisms of patterns of fire complexity, which were shown to be sensitive to data quality. Our results provide additional information about the creation of spatially heterogeneous landscapes. Furthermore, they illustrate the potential use of spatial metrics for a more detailed characterization of fire regimes and provide novel information for ecosystems-based land management.

Abstract (sommario):

ABSTRACTThe influence of land use on soil bio-resources is largely unknown. We examined the communities of arbuscular mycorrhizal (AM) fungi in wheat-growing cropland, natural areas, and seminatural areas along roads. We sampled the Canadian prairie extensively (317 sites) and sampled 20 sites in the Atlantic maritime ecozone for comparison. The proportions of the different AM fungal taxa in the communities found at these sites varied with land use type and ecozones, based on pyrosequencing of 18S rRNA gene (rDNA) amplicons, but the lists of AM fungal taxa obtained from the different land use types and ecozones were very similar. In the prairie, the Glomeraceae family was the most abundant and diverse family of Glomeromycota, followed by the Claroideoglomeraceae, but in the Atlantic maritime ecozone, the Claroideoglomeraceae family was most abundant. In the prairie, species richness and Shannon's diversity index were highest in roadsides, whereas cropland had a higher degree of species richness than roadsides in the Atlantic maritime ecozone. The frequencies of occurrence of the different AM fungal taxa in croplands in the prairie and Atlantic maritime ecozones were highly correlated, but the AM fungal communities in these ecozones had different structures. We conclude that the AM fungal resources of soils are resilient to disturbance and that the richness of AM fungi under cropland management has been maintained, despite evidence of a structural shift imposed by this type of land use. Roadsides in the Canadian prairie are a good repository for the conservation of AM fungal diversity.

Abstract (sommario):

Responses to drought within a single species may vary based on plant developmental stage, drought severity, and the avoidance or tolerance mechanisms employed. Early drought stress can restrict emergence and seedling growth. Thus, in areas where water availability is limited, rapid germination leading to early plant establishment may be beneficial. Alternatively, germination without sufficient water to support the seedling may lead to early senescence, so reduced germination under low moisture conditions may be adaptive at the level of the population. We studied the germination response to osmotic stress of diverse chile pepper germplasm collected in southern Mexico from varied ecozones, cultivation systems, and of named landraces. Drought stress was simulated using polyethylene glycol solutions. Overall, survival time analysis revealed delayed germination at the 20% concentration of PEG across all ecozones. The effect was most pronounced in the genotypes from hotter, drier ecozones. Additionally, accessions from wetter and cooler ecozones had the fastest rate of germination. Moreover, accessions of the landraces Costeño Rojo and Tusta germinated more slowly and incompletely if sourced from a drier ecozone than a wetter one, indicating that slower, reduced germination under drought stress may be an adaptive avoidance mechanism. Significant differences were also observed between named landraces, with more domesticated types from intensive cultivation systems nearly always germinating faster than small-fruited backyard- or wild-types, perhaps due to the fact that the smaller-fruited accessions may have undergone less selection. Thus, we conclude that there is evidence of local adaptation to both ecozone of origin and source cultivation system in germination characteristics of diverse chile peppers.

Abstract (sommario):

In this paper is marked the contribution of the Ecozones to the Ecostratigraphy. As an example we use the drillings (Ml, M2, M3, M4, M6, MIO) coming from the Plio- Pleistocene basin of the Magoula- Karatoulas (Pyrgos, Peloponnesus). Based on the detailed stratigraphical and paleoecological studies of the postalpine sediments (VAGIAS et al. 1995) of the formation of Vounargo (HAGEMAN 1977,1979 & ΚΑΜΠΕΡΗΣ 1987) we attempt to define 15 ecozones, as it is understood the layer or the whole of the layers, which is characterized by an association of fossils (at the level of species, genus or family). The Ecozone reflects the evolution of a sedimentary basin from the bathymetrical point of view as well as the transgressions and the regressions. The Ecozones are often related with the curve of the change of the sea level. The transgression is characterized by the rich fossil associations (species and individuals), while the regression is characterized by a diminution of species and individuals. There are also 11 white spots, which can not be enclosed in Ecozones. They are observed in the drillings M2, M3, M4, M6 and MIO.

Abstract (sommario):

We analyzed one of the inseparable components of road landscapes of Ukraine, their ecozones. As noted, road landscapes are divided into three categories: road landscape-en- gineer systems (RLESs), road landscape-technogenic systems (RLTSs) and road landscapes proper (RLP). Depending on those categories of road landscapes, there form respective road ecozones. Most distinctively, they become structured and developed over the process of constructing and functioning of RLESs. Therefore, the objectives of our research were the structure, typology, properties and significance of ecozones, mostly those of road landscape-engineer systems for the purpose of their rational exploitation. The objects of the research were RLESs of Ternopil-Khemel- nytskyi-Vinnytsia-Uman-Kropyvnytskyi (M-12) and Kyiv-Odesa (M-5). The research was carried out using the basic principles of landscape science – emergence, cause and effect relationships, history, comparability; methods of analysis, synthesis, modeling, map- ping, GIS-technologies using the software: graphic editors CorelDRAW and Adobe Photoshop, and also open-source network of satellite images Google Earth and other. The notion of road ecozone is considered as a complex ecological structure that is formed and developed over the process of functioning of road landscapes. In more details, we have analyzed the ecozones of modern road landscape-engineer systems M-12 and M-5 which have long been actively operating. Field landscape-science-oriented and ecological studies of ecozones of those RLESs over the period of 2019-2021 made it possible to distinguish and substantiate ten microecozones in their structure. Their specific features are conditioned by specifics of the structure and ecologic condition of previous landscape complexes – the fundamentals of modern RLESs; spatial-temporal specifics of the formation; «linear» spread; dependence on the func- tioning of one type of transport (automobile) and purpose. The features of microecozones are conditioned by land allocated to roads, technical impact, chemical contamination, contamination of soil, aquatic and air contaminations, acoustic and lighting impacts, and esthetic and landscape contaminations. Over the process of further studies, it is possible to distinguish other microecozones, specifically those of biotic and geological impacts, and also uniting certain microecozones into groups. We analyzed one of typical features of road ecozones – their asymmetry. We distinguished and characterized three types of asymmetry of road ecozones – wind-caused, orographic and landscape asymmetries. Not always do their vectors of development coincide. We should note that over the process of functioning of RLTSs and SRLs, there also develop roadside ecozones with respective set of microecozones, though they need additional studies. Further study of ecozones in road landscapes would allow for more thorough planning and forming of their structure, functioning, im- pact on human health and environment. Road landscapes of any category need to be re-constructed into a system of complex purpose – transport, scientific, recreational and esthetic.

Abstract (sommario):

Wildfire is a major disturbance in boreal terrestrial ecosystems. Characterizing fire regimes and projecting fire recurrence intervals for different biomes are important in managing those ecosystems and quantifying carbon dynamics of those ecosystems. This study used Canadian wildfire datasets, 1980–1999, to characterize relationships between number of fires and burned area for 13 ecozones and to calculate wildfire recurrence intervals in each ecozone. For the study period, wildfires were found to follow power–law relationships between frequency densities (number of fires normalized to unit bins) and burned areas in all ecozones. Power–law frequency–area relationships also held for both anthropogenic fires and natural fires in the 1980s and 1990s. For each Canadian ecozone using the parameters of the power–law frequency–area distributions, fire recurrence intervals were then calculated for wildfires equal to or larger than a given size of burned area. Fire recurrence intervals ranged from 1 to 32 years for burned areas >2 km2, and from 1 to 100 years for burned areas >10 km2 in every 10 000-km2 spatial area for each ecozone. The information obtained through characterizing the wildfires and the fire recurrence intervals calculated in this study will provide guidance to wildfire risk managers throughout Canada. The findings of this study will also be a benefit to future efforts in quantifying carbon dynamics in Canadian boreal terrestrial ecosystems.

Abstract (sommario):

The global distribution of forest trees is essential for monitoring land-use sustainability. For this reason, FAO developed the Global Forest Survey (GFS), a systematic regional level survey with a homogeneous sampling design. Preliminary results revealed an interest in analyzing “Trees Outside Forests” (TOFs). We analyzed more than 11,150 sample GFS plots in temperate FAO-ecozones in Europe through a photo-interpretation approach using FAO’s Collect Earth platform. Our results showed that forest land was the most predominant use of land (41%) in temperate FAO-ecozones in Europe in 2015. Forest IPCC land use followed a moderate upward trend from 2000 to 2015 (0.2%). Trees Outside Forests in temperate FAO-ecozones in Europe accounted for 22% of the inventoried area. Trees Outside Forests represent 30% and 48% of cropland and grassland IPCC land uses, respectively, as well as 75% in settlement uses. Comparing our results with previous studies on the Mediterranean, temperate FAO-ecozone TOFs showed a downward trend in Europe and an upward trend in the Mediterranean area, despite its smaller surface area. The greening of the Common Agricultural Policy may increase the extension of TOFs, although our results may indicate that this effect is not yet evident in the field.

Abstract (sommario):

The Byron Bay Sewage Treatment work consists of a conventional treatment system discharging into an 8 ha wetland. The wetland was constructed around the dune and swale remnants of a coastal beach ridge formation. The wetland design incorporated stands of broad leaf paperback, Melaleuca quinquenervia , in two distinct Sections, separated by, and each preceded by, open water Sections fringed by predominantly emergent macrophytes. Spatial and temporal patterns in sediment phosphorus concentrations were examined using sediment cores. Core consisted of three main sediment types - surface organic accumulation, pre-existing organic layers and sand. Results suggest that the design and management of wetland systems should be aimed at maximising the deposition of sediment (and associated phosphorus) and minimising subsequent phosphorus release from the sediment. This might be achieved through the removal of accumulated organic sediments to retain the phosphorus adsorption capacity of the system, consideration of wind direction during periods of high (floating) plant growth (as detritus may accumulate along the up-wind edges of the wetland), incorporation of deep zones to minimise sediment phosphorus release and the inclusion of stands of M. quinquenervia. Results highlight pitfalls in the prevailing approach to wetland design, which ignore the complex functions which occur in natural wetland systems. A more holistic approach incorporating a high diversity of ecozones in wetland design is proposed, in effect mimicking natural systems.

Testo completo

Abstract (sommario):

Il lavoro di laurea è inteso come una valutazione del modello LANCA, usato per valutare gli impatti dovuti al cambiamento di uso del suolo. Il modello fa uso di coefficienti di impatto, o meglio, di fattori di caratterizzazione (CF), che esprimono l’impatto specifico per tipo di uso del suolo e per superficie cambiata rispetto a una condizione di riferimento naturale. Il modello prevede dei CF di default calcolati a base nazionale. L’ipotesi è che l’uso di CF di default calcolati su base nazionale sia meno precisa di CF basati sulla classificazione FAO di Zone Globali Ecologiche (ecozona), oppure di altri fattori morfologici. Per testare l’ipotesi si è allestito un confronto tra i CF relativi alla categoria di impatto Land Use del modello LANCA per due nazioni, Italia e Germania, rappresentativi di diverse ecozone. Sono stati calcolati quindi i CF a livello nazionale e i CF sito specifici, nella misura di circa 30 per nazione in maniera random in maniera tale che i CF ricadano in ecozone comuni alle due nazioni. Quindi sono stati calcolati diversi parametri statistici quali Media, Moda, Varianza delle nazioni ed è stata colta la correlazione dei valori di CF in relazione alla ecozona e alla posizione precisa del punto di campionamento. È stata messa in risalto la varianza tra valore di CF nazionale e valori di CF precisi all’interno della stessa nazione e tra nazioni. Dal lavoro svolto, si è ottenuto che la popolazione dei dati di CF calcolata su base nazionale (attuale valore di default) sia rappresentativa solo nel CF Physicochemical filtration reduction potential, mentre nei restanti CF non lo è. Questi risultati avvalorano l’ipotesi di lavoro, ovvero che i fattori di caratterizzazione dovrebbero essere tabellati per ecozone, tenendo conto della pendenza dei versanti (LS), piuttosto che su base nazionale.

Abstract (sommario):

La generación de residuos sólidos urbanos (RSU) está relacionada con el consumo de bienes y servicios, y este a su vez, con el ingreso y los niveles de vida de la comunidad que se estudia, por lo tanto, la generación de los residuos será distinta entre cada región. Si bien, se han realizado esfuerzos que integran la regulación jurídica, el ecodiseño de productos, la inclusión de nuevos materiales, la instalación de infraestructura y la disposición de sitios, así como aportes significativos de la ciencia y la participación de la sociedad civil y empresarial, la realidad muestra que el manejo adecuado de los residuos sigue siendo una asignatura pendiente. Tal es el caso de México, en donde se desechan diariamente 102,895 ton de RSU, donde el 46.42% son orgánicos, 31.56% inorgánicos y el 22.02% restante son misceláneos (residuos que no tienen un valor económico y material en el mercado productivo), es decir, que el 77.98% puede ser aprovechado. No obstante, solo se logra recuperar el 9% de estos, y es a través del sector informal (recolectores/pepenadores), y solo residuos inorgánicos. En el mejor de los casos la totalidad de los residuos son depositados en los rellenos sanitarios, pero saturan su capacidad operativa y perpetúan que el manejo de los RSU siga una cadena lineal inadecuada, que promueve escenarios de contaminación en el aire, suelo, agua, afecta a diversos ecosistemas, suscita la extracción de recursos naturales, se incrementan los costos operativos para su manejo, se da la proliferación de fauna y vectores que ponen en riesgo a la salud de la población. Aun estando conscientes de la situación, sigue existiendo una desarticulación de acciones que favorezcan la recuperación y valorización de los residuos a través de la integración de los generadores. Por ello, el objetivo de esta investigación es diseñar un sistema integral de RSU considerando como ejes de acción: la educación ambiental, las tecnologías limpias, la optimización de procesos, la logística de recuperación y valorización, y la generación de redes de coparticipación. Se ha elegido al Centro Histórico de Cuernavaca, Morelos, México, como sitio de estudio, por su relevancia social, ambiental y económica, y por el número considerable de personas que interactúan en el lugar, además de que cuenta con dos características adicionales que permiten el poder ser intervenido: la declaratoria de Ecozona (2015), y las condiciones de su sistema de recolección que se pueden optimizar. Actualmente se está trabajando sobre la primera área del proyecto, que consiste en el acercamiento con las unidades económicas (UE), la identificación de hábitos de consumo/desecho, posibles colaboradores, reconocimiento de impactos, caracterización de los RSU, y en el diseño del prototipo de triturador, este último va encaminado hacia el manejo adecuado de los residuos orgánicos, a través de la evaluación de tres sistemas de compostaje. La meta final del proyecto es pilotearlo en el sitio de estudio, y a partir de los resultados establecer un sistema que pueda ser adaptado a otros escenarios, otros sitios históricos, por ejemplo.
