The New Holland mouse (Pseudomys novaehollandiae) was first recorded at Wilson?s Promontory in 1972 in heathland vegetation, but has not been located in this habitat subsequently. The species was not trapped again until 1993 when it was found in calcarenite dune woodland on the Yanakie Isthmus. The aims of this study were to assess the population dynamics and habitat use of the species in this dune habitat. Mark-recapture trapping was conducted at three sites from 1999 to 2002. One site was located on low (0 - 5 m), flat sand dunes and open swales, another on medium (5 ? 10 m) vegetated dunes, and the third on high (20 m) steep vegetated dunes. The three sites had not been burnt for 30 to 50 years. The abundance of P. novaehollandiae was related to understorey vegetation density and differences in population densities on the sites are likely to be related to the primary succession stages on the sand dunes, rather than fire history. The maximum density (24 ha-1) recorded at one site was very high compared to other Victorian populations, however this was followed by a substantial decline in numbers within the year. At another site a small population declined to extinction. Populations on the isthmus are thus capable of achieving high densities but may decline quickly. Rainfall patterns may have affected the population fluctuations, but further research is required to elucidate fully the factors involved in the long-term dynamics of this species.

Abstract Dasyurids are small mammals that can conserve energy and water by using shelters that insulate against extreme conditions, prevent predation, and facilitate torpor. To quantify the diurnal sheltering requirements of a poorly known, endangered dasyurid, the sandhill dunnart, Sminthopsis psammophila, we radiotracked 40 individuals in the Western Australian Great Victoria Desert between 2015 and 2019. We assessed the effect of habitat class (broad habitat features), plot-level (the area surrounding each shelter), and shelter characteristics (e.g., daily temperature ranges), on shelter selection and sheltering habitat preferences. Two hundred and eleven diurnal shelters (mean of 5 ± 3 shelters per individual) were located on 363 shelter days (the number of days each shelter was used), within mature vegetation (mean seral age of 32 ± 12 years postfire). Burrows were used on 77% of shelter days and were typically concealed under mature spinifex, Triodia spp., with stable temperature ranges and northern aspects facing the sun. While many burrows were reused (n = 40 across 175 shelter days), spinifex hummock shelters typically were used for one shelter day and were not insulative against extreme temperatures. However, shallow scrapes within Lepidobolus deserti hummock shelters had thermal advantages and log shelters retained heat and were selected on cooler days. Sminthopsis psammophila requires long-unburned sheltering habitat with mature vegetation. Summer fires in the Great Victoria Desert can be extensive and destroy large areas of land, rendering them a key threat to the species. We conclude that the survey and conservation of S. psammophila requires attention to long-unburned, dense lower stratum swale, sand plain, and dune slope habitats, and the tendency of S. psammophila to burrow allows the species to survive within the extreme conditions of its desert environment.

Pseudomys novaehollandiae is ‘Endangered’ in Victoria, where it is presently considered to be extant at only three localities Loch Sport, Providence Ponds, and Wilsons Promontory. This study aimed to determine indicators of suitable habitat for the species that could assist in identifying potential habitat and sites for planned re-introductions as part of a recovery program. Vegetation and site data (soils, topography, rainfall, fire age-time since fire) were assessed at localities where P. novaehollandiae was recorded. The species occurred in five structural vegetation groups - open-forest, woodland, heathland, shrubland, grassland, with the most common being open-forest and woodland. Grassland and shrubland were restricted to coastal sand-dunes in south Gippsland. Understorey vegetation at most sites was dominated by sclerophyllous shrubs ranging in cover from 10 - 70%. Classification of quadrats produced eight floristic groups in which the trend was for quadrats to cluster according to geographical location. Ordination confirmed the classification pattern and vector-fitting produced significant correlations between vector points and five variables: species richness, latitude, longitude, fire age and annual rainfall. The study identified a range of vegetation communities where P. novaehollandiae occurs and provided evidence that the species is not restricted to floristically rich and diverse heathlands. The findings can be used to determine further localities with suitable habitat. However, factors other than vegetation are also likely to be important in predicting suitable habitat.

The present paper completes a taxonomic revision of Cassinia subg. Cassinia, a group of 35 species separated from subg. Achromolaena by the structure of its inflorescence (capitula arrangement approximately dichasial, giving rise to flat- or round-topped compound inflorescences, as opposed to the irregular or alternate arrangement of capitula in subg. Achromolaena, where the overall shape of the inflorescence is conical or elongate). The seven species of Cassinia sect. Cassinia (C. aculeata, C. thinicola, C. wilsoniae, C. longifolia, C. aureonitens, C. trinerva and C. cinerea) are keyed, described and illustrated, with discussion of ecology, distribution and variation. Cassinia aculeata subsp. nova-anglica Orchard, C. thinicola Orchard, C. wilsoniae Orchard and C. cinerea Orchard are described as new. Cassinia aculeata is a variable and widespread species. Four morphological variants are described and discussed, although not formally named. Previously suggested hybridisation between C. aculeata and Ozothamnus obcordatus is discussed, and dismissed. A new subspecies, narrowly endemic to the New England region of New South Wales (NSW), and separated by 350 km from subsp. aculeata, is described. Cassinia longifolia is similarly widespread and variable, particularly in indumentum and leaf shape. Again, four more or less distinct local morphological variants are described, but they are not formally named because of problems with satisfactory circumscription. Cassinia thinicola is newly segregated from C. aculeata. It is a strikingly distinct species, confined to coastal habitats north and south of Newcastle, distinguished by its (usually) lack of hairs on the upper leaf surface, ochre-coloured inflorescences and compact habit. Cassinia wilsoniae, confined to Wyperfeld National Park in western Victoria, has hitherto been largely overlooked, with specimens assigned to a broadly circumscribed ‘C. uncata’, or C. aculeata or C. longifolia. It is geographically widely separated from all of these taxa. It is unusual in the genus, in being confined largely to the summits of consolidated sand dunes. It has rather small inflorescences with few capitula, and these are ochre-coloured. The leaf margins are strongly revolute, almost completely covering the midrib below, unlike related taxa where the midrib remains uncovered. Cassinia cinerea is a rare species confined to south-eastern Queensland, and hitherto confused with C. laevis and C. collina, both in subg. Achromolaena (and thus with conical inflorescences). It also differs from both in a range of indumentum and leaf characters. The remaining, previously recognised, species are redescribed in detail, and their nomenclature, variation, ecology and distribution are discussed as required.

Sand-Dune Vegetation of Igneada Coast in the Thracian Part of TurkeyIgneada is located in the northwest part of Turkey on the Black Sea coast and it is also near the national border between Turkey and Bulgaria. The Igneada region was accepted as one of the most important plant areas of Turkey. In this work, a study was made on the phytosociological structure of Igneada sand dune vegetation, which is the one of the important components of the richness in the region. At the end of the assessment of the data, 3 communities were defined. These communities areOtantho-Leymetum sabulosi, Medicago rigidula-Cionura erectabasal community and meadow behind the sand dune. The part of the sand dune closest to the sea has width of 30 m, ascends with a specific inclination and has no vegetation coverage. Behind this part,Otantho-Leymetum sabulosioccurs at places where the sand dune has an unstable structure. TheMedicago rigidula-Cionura erectabasal community appears behindOtantho-Leymetum sabulosiand the sand dune has a stable structure at these areas. Behind these communities, another vegetation belt occurs, formed by the species that are cosmopolite or characteristic for meadow vegetation.

An experimental study was designed to investigate the demographic mechanisms by which annual plants inhabiting desert sand dunes respond to local gradients in the stability of the sand. The results indicated that individual plants emerging at different topographic positions along the dune experience different probabilities of survival and reproduction. The general trend observed was a decrease in seedling survival, plant biomass, fecundity, reproductive allocation, and fruit weight from the relatively stable, interdune corridor towards the unstable crest of the dune. However, all of these demographic responses were highly species-specific, indicating that coexisting annual species respond differentially to underlying patterns of spatial heterogeneity in the stability of the sand. These results suggest that local-scale spatial heterogeneity in sand stability may be important in promoting coexistence of desert sand dune annuals.

SynopsisWith the gradation of intensities of environmental factors from the strand-line to stable inland areas, coastal dunes show many ecological phenomena especially clearly. These are reviewed broadly, with some emphasis on topics on which important advances are being made. The nutrient status of dune soil and changes with time are shown with reference to several dune systems. Changes in major nutrients are given for Braunton Burrows, north Devon, where the influence of nitrogen fixation by Lotus corniculatus is illustrated. The effects of sand burial on plants are considered, and details given of the root systems of vigorous and relict marram; factors which may affect its decline in vigour are reviewed. Also discussed is the likely significance of nematodes in the decline of Hippophaë rhamnoides. Reasons for the richness of the dune flora are considered and also some autecological studies. At the physiological level, reference is made to the water relations of plants and at the biochemical level to the occurrence and possible ecological importance of stress metabolites. Life strategies, phenology, survivorship, competition and the population ecology of dune plants are reviewed and also the interaction of ragwort (Senecio jacobaea) and cinnabar moth (Tyria jacobaeae). The population genetics of dune plants is illustrated by reference to Festuca rubra and Ammophila arenaria and of animals to Cepaea nemoralis.The abundance and ecological relationships of the invertebrate fauna are exemplified by surveys at Spurn Point, extensive investigations on spiders and the influence of marram on arthropod communities. The ecology of the natterjack load is considered in relation to conservation and the effects of large animal grazers in relation to the diversity of vegetation.

The Bigstick and Seward Sand Hills are possibly two of the oldest dune fields within the late Wisconsin glaciated regions of the Northern Great Plains. As with most Northern Great Plains dune fields, source sediments are former proglacial outwash sands. Thus, Holocene dune construction is primarily related to spatial–temporal variations in surface cover and transport capacity, rather than renewed sediment input. However, eolian landscape reconstructions on the Northern Great Plains have been temporally constrained to recent periods of activity, as older episodes of deposition are typically reworked by younger events. In this study, sediment cores from shallow lacustrine basins and interdune areas provide an improved record of Holocene eolian sand deposition. Eolian sand accumulation in the interdunes and basins occurred between 150 and 270 years ago, 1.9 and 3.0 ka, 5.4 and 8.6 ka, and prior to ca. 10.8 ka. These episodes of sand accumulation were bracketed by lacustrine deposition and soil formation, which represented wetter conditions. Other than mid-Holocene dune activity, which may be related to peak warmth and aridity, most periods of eolian sand accumulation coincided with cooler but drier climatic events such as the Younger Dryas, late-Holocene cooling prior to the Medieval Climatic Anomaly, and the ‘Little Ice Age’. These depositional episodes are also spatially represented by other dune fields in the region, providing a broad-scale view of the connections between past climatic events and eolian landscape evolution on the Northern Great Plains.

Sand trapping fences are a widely used nature-based solution to initiate dune toe growth along sandy shorelines for coastal protection. At present, the construction of sand trapping fences is based on empirical knowledge, since only a few scientific studies investigating their efficiency exist. However, the restoration and maintenance of beach-dune systems along the coast requires knowledge of the interaction between the beach-dune system and the sand trapping fences to provide guidance for coastal managers on how and where to install the fences. First, this review gives an overview of the typical aerodynamic and morphodynamic conditions around a single porous fence and the influence of various fence height and porosity values to understand the physical processes during dune establishment. Second, different approaches for evaluating the efficiency of sand trapping fences to trap sediment are described. This review then highlights significant differences between sand trapping fence configurations, nationally as well as internationally, regarding the arrangement, the materials used, and the height and porosity. In summary, it is crucial to enable an intensive exchange among the respective coastal authorities in order to create uniform or transferable guidelines taking local conditions into account, and thus work collaboratively on the idea of sand trapping fences as a nature-based solution in coastal areas worldwide.

Abstract. Understanding dune ecosystem responses to multi-scale environmental changes can provide the framework for reliable forecasts and cost-efficient protocols for detecting shifts in prevailing coastal dynamics. Based on the hypothesis that stress and disturbance interact as primary community controls in coastal dunes, we studied the fine-scale floristic assembly of foredune vegetation, in its relation to topography, along regional and local environmental gradients in the 200 km long coastline of northern Portugal, encompassing a major biogeographic transition in western Europe. Thirty topographic profiles perpendicular to the shoreline were recorded at ten sites along the regional climate gradient, and vegetation was sampled by recording the frequency of plant species along those profiles. Quantitative topographic attributes of vegetated dune profiles (e.g. length or height) exhibited wide variations relatable to differences in prevailing coastal dynamics. Metrics of taxonomic diversity (e.g. total species richness and its additive beta component) and of the functional composition of vegetation were highly correlated to attributes of dune topography. Under transgressive dynamics, vegetation profiles have fewer species, increased dominance, lower turnover rates, and lower total vegetation cover. These changes may drive a decrease in structural and functional diversity, with important consequences for resistance, resilience and other ecosystem properties. Moreover, differences in both vegetation assembly (in meta-stable dunes) and response to increased disturbance (in eroding dunes) between distinct biogeographic contexts highlight a possible decline in facilitation efficiency under extreme physical stress (i.e. under Mediterranean climate) and support the significance of functional approaches in the study of local ecosystem responses to disturbance along regional gradients. Our results strongly suggest that assessing fine-scale community assembly can provide insights on the relation between dune vegetation, environmental filters and ecosystem processes. A combination of cost-efficient indicators from dune topography and vegetation is thus suggested as a promising approach to survey, forecast and monitor changes in coastal dune ecosystems.

Abstract Coastal dunes are experiencing increases in vegetation cover and reduced mobility levels in many sites around the world. Ecology-led approaches to coastal dune management perceive this change as ‘undesirable’ because the increase in plant cover leads to a reduction in partially vegetated to bare sand habitats and the species depending on them. This has generated a shift in the management paradigm where the objective is to revert this trend by intervening in the landscape, with actions ranging from re-introducing grazing and mowing, to mechanical removal of dune form and vegetation (dune ‘rejuvenation’). In some cases, such as many coastal dunes in Britain, this has also led to low controls on visitor pressure and allowing/promoting human trampling as a ‘natural’ way to free up areas of bare sand. This commentary critically analyses the main principles (and terminology) underlying this relatively recent shift in management paradigm, and questions assumptions such as ‘bare sand is good’ and/or ‘mobility is natural’ in the context of dune evolutionary cycles and responses to abiotic and biotic drivers. We review the limitations and dangers of this approach and argue that it is not sustainable given the current climatic and environmental conditions, and that it can increase the risk of coastal erosion and force dune systems to deviate from adapting and changing to direct/indirect drivers. Finally, we present the benefits of a management approach that focuses on minimizing human impacts so that natural processes continue to occur.

A study of grazing patterns on a coastal dune system on South Stradbroke Island, Queensland, by two species of wallaby was undertaken. Utilisation of sand spinifex (Spinifex sericeus) by agile wallabies (Macropus agilis) and swamp wallabies (Wallabia bicolor) was highly variable between different sites on the dune system. Although wallaby activity on secondary dune strata was significantly higher than on the primary dune, this was not reflected statistically in spinifex grazing levels. However, spinifex stolons on the toe of the primary dune were heavily grazed. Grazing levels on dune systems on the island were negatively associated with the width of the frontal dune and the relative area of open forest vegetation adjacent to the dune system.

Abstract. Dune development along highly dynamic land–sea boundaries is the result of interaction between vegetation and dune size with sedimentation and erosion processes. Disentangling the contribution of vegetation characteristics from that of dune size would improve predictions of nebkha dune development under a changing climate, but has proven difficult due to the scarcity of spatially continuous monitoring data. This study explored the contributions of vegetation and dune size to dune development for locations differing in shelter from the sea. We monitored a natural nebkha dune field of 8 ha, along the coast of the island Texel, the Netherlands, for 1 year using an unmanned aerial vehicle (UAV) with camera. After constructing a digital surface model and orthomosaic we derived for each dune (1) vegetation characteristics (species composition, vegetation density, and maximum vegetation height), (2) dune size (dune volume, area, and maximum height), (3) degree of shelter (proximity to other nebkha dunes and the sheltering by the foredune). Changes in dune volume over summer and winter were related to vegetation, dune size and degree of shelter. We found that a positive change in dune volume (dune growth) was linearly related to initial dune volume over summer but not over winter. Big dunes accumulated more sand than small dunes due to their larger surface area. Exposed dunes increased more in volume (0.81 % per dune per week) than sheltered dunes (0.2 % per dune per week) over summer, while the opposite occurred over winter. Vegetation characteristics did not significantly affect dune growth in summer, but did significantly affect dune growth in winter. Over winter, dunes dominated by Ammophila arenaria, a grass species with high vegetation density throughout the year, increased more in volume than dunes dominated by Elytrigia juncea, a grass species with lower vegetation density (0.43 vs. 0.42 (m3 m−3) week−1). The effect of species was irrespective of dune size or distance to the sea. Our results show that dune growth in summer is mainly determined by dune size, whereas in winter dune growth was determined by vegetation type. In our study area the growth of exposed dunes was likely restricted by storm erosion, whereas growth of sheltered dunes was restricted by sand supply. Our results can be used to improve models predicting coastal dune development.

Abstract The sand cat is one of the world’s least studied small cats. Our camera-trap survey, one of the largest undertaken in a desert system, generated over 1500 images of the species across 100 camera-traps distributed systematically over the 2400 km2 core area of the Uruq Bani Ma’arid Protected Area of the Empty Quarter, Saudi Arabia. The study revealed a much more significant and widespread sand cat population in the ecosystem than previously understood. Sand cats were detected across one-third of the core area in all major habitats, comprising escarpment plateau, sand dunes and interdunal gravel valleys. The species showed a marginal preference for the interior parallel dune system with interspersed gravel valleys where they also preferred sand dunes over the gravel valley in the hot season. There was no evidence of strong spatial interactions with other predators. The ecosystem’s larger predators (Arabian red fox and honey badger, and all records of wild and feral cats) were primarily associated with the escarpment plateau. The smaller Rueppell’s fox was the only other carnivore more consistently present in the main dune system. Sand cats were strictly nocturnal and 14% more active in the hot season than the cool season.

Aspects of physicochemical limnology and the zooplankton, littoral invertebrates and fish of dune lakes on Fraser Island are described and compared. The comparisons highlight differences between perched, humic lakes and the non-humic Lake Wabby, a water-table window with some morphometric and biological features typical of dune barrage lakes. Lake Wabby has been partially infilled by a mobile sand dune moving mainly in a north-westerly direction across the northern end of the lake. The maximum rate of dune advance estimated from aerial photos was 5.03 m year-1, between 1948 and 1958. Sand infilling between 1975 and 1984 altered the morphometry and substrate characteristics of the lake's eastern region and reduced maximum depth from 13.0 to 11.5 m and volume by 43%. The number of benthic invertebrates was reduced from 14 taxa in 1975 to six taxa in 1984; there was also a significant decrease in abundance of benthic Chironomini during this period (ANOVA, P < 0.05). In both years, an undescribed species of Conochironomus was the most abundant benthic invertebrate in Lake Wabby (250-700 individuals m-2). A new genus of Chironomini (near Paralauter borniella) was discovered. Lake Wabby supported 11 species of fish in 1975 and 1984, but the perched lakes had only one or two species. The five most abundant species in Lake Wabby in 1975 showed evidence of partitioning of food resources, of which the main components were benthic invertebrates and filamentous algae. Allochthonous food resources were not important in fish diets. The possible long-term effects of sand infilling on food resources, fish diets and the composition of the zooplankton in Lake Wabby are discussed.

Abstract. Dune plant assemblages are affected by severe conditions, which makes them excellent models for studying the effects of species interactions and environmental conditions on community structure. We evaluate the relationship between the structure of dune communities, local environmental conditions and the suitability of climatic conditions for their characteristic species. Using data from an extensive survey of xerophytic inland sand dune scrub communities from Portugal – one of the most threatened habitat types of Europe – we identify the main gradients of vegetation composition, the different types of communities and their indicator shrub species. Then, we model the geographical responses of these species to the environment. Soil organic matter, isothermality and the habitat suitability for Stauracanthus genistoides defined the distribution of three shrub communities in the study area.

A Gram-stain-positive, spore-forming, rod-shaped, motile, strictly aerobic bacterial strain, designated CAU 1051T, was isolated from a sand dune and its taxonomic position was investigated using a polyphasic approach. Strain CAU 1051T grew optimally at pH 5.0 and 30 °C. NaCl was not required for growth but up to 10.0 % (w/v) NaCl was tolerated. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain CAU 1051T formed a distinct lineage within the genus Oceanobacillus and was most closely related to Oceanobacillus profundus CL-MP28T, Oceanobacillus caeni S-11T, and Oceanobacillus picturae LMG 19492T (96.8 %, 95.6 % and 95.3 % similarity, respectively). DNA–DNA reassociation analysis showed that strain CAU 1051T displayed 28.2±0.7 % relatedness to O. profundus KCTC 13625T. Strain CAU 1051T contained MK-7 as the only isoprenoid quinone and anteiso-C15 : 0 as the major fatty acid. The cell wall peptidoglycan of strain CAU 1051T contained meso-diaminopimelic acid. The polar lipids were composed of diphosphatidylglycerol, phosphatidylglycerol, six unidentified phospholipids, an unidentified glycolipid, and six unidentified polar lipids. The major whole-cell sugars were glucose and ribose. The DNA G+C content was 36.3 mol%. On the basis of phenotypic data and phylogenetic inference, strain CAU 1051T represents a novel species of the genus Oceanobacillus for which the name Oceanobacillus chungangensis sp. nov. is proposed. The type strain is CAU 1051T ( = KCTC 33035T = CCUG 63270T).

An unusual shell deposit at Moyjil (Point Ritchie), Warrnambool, in western Victoria, has previously been dated at 67±10 ka and has features suggesting a human origin. If human, the site would be one of Australia’s oldest, justifying a redetermination of age using amino acid racemisation (AAR) dating of Lunella undulata (syn. Turbo undulatus) opercula (the dominant shellfish present) and optically stimulated luminescence (OSL) of the host calcarenite. AAR dating of the shell bed and four Last Interglacial (LIG) beach deposits at Moyjil and Goose Lagoon, 30 km to the west, confirmed a LIG age. OSL analysis of the host sand revealed a complex mixing history, with a significant fraction (47%) of grains giving an early LIG age (120–125 ka) using a three-component mixing model. Shell deposition following the LIG sea-level maximum at 120–125 ka is consistent with stratigraphic evidence. A sand layer immediately below the shell deposit gave an age of ~240 ka (i.e. MIS 7) and appears to have been a source of older sand incorporated into the shell deposit. Younger ages (~60–80 ka) are due to bioturbation before calcrete finally sealed the deposit. Uranium/thorium methods were not applicable to L. undulata opercula or an otolith of the fish Argyrosomus hololepidotus because they failed to act as closed systems. A U–Th age of 103 ka for a calcrete sheet within the 240 ka sand indicates a later period of carbonate deposition. Calcium carbonate dripstone from a LIG wave-cut notch gave a U–Th age of 11–14 ka suggesting sediment cover created a cave-like environment at the notch at this time. The three dating techniques have collectively built a chronology spanning the periods before and after deposition of the shell bed, which occurred just after the LIG sea-level maximum (120–125 ka).

The Mediterranean coastal dune habitat of Israel is diminishing rapidly, mostly due to massive urbanization, changes in habitat characteristics caused by dune stabilization and the presence of Acacia saligna, an invasive species brought to Israel for the purpose of dune stabilization. In this study we document the effect of sand stabilization on the composition of small mammal communities in the Ashdod-Nizzanim sands, Israel. We analyzed differences in species diversity and abundance for species of rodents in four types of habitat: unstable (mobile) sand dune, semi-stabilized dune, inter-dune depression and a plot of the invasive Acacia saligna. Rodent communities were found to undergo gradual changes concurrently with the stabilization of the sands. The mobile dune was the only habitat in which the strict psammophiles Jaculus jaculus and Gerbillus pyramidum were captured in abundance. No species commensal with human were captured neither in the mobile nor in the semi-stabilized dunes. However, in the inter-dune depression there was quite a large representation of Mus musculus, a rodent commensal with humans. The Acacia saligna plot had the lowest number of captures and the lowest rodent biomass calculated, with Mus musculus composing nearly half of the captures. The results of this study demonstrate that stabilization of the sands in Ashdod-Nizzanim area is associated with the disappearance of psammophile rodents and the appearance of species commensal with humans. In order to preserve the habitat for psammophile rodents, measures should be taken to halt the spread of acacia and the continuing stabilization of the sands.

Most of Australia’s desert dune fields are stable; however, wildfires may reduce vegetation and biological soil crust cover so that sand movement may take place until vegetation recovers. In this study, we aimed to study the recovery rate of vegetation cover in spinifex (Triodia)-dominated desert dunes following wildfires using satellite imagery-derived spectral indices to: (1) determine for how long after fire these dunes may be active until critical levels of vegetation cover are attained; (2) determine which spectral index is the most suitable for monitoring vegetation recovery in this area. We have used a combination of MODIS, Landsat, Aster and QuickBird images to analyse vegetation cover following fire at various spatial and temporal scales, in the Great Victoria Desert, WA. The following spectral indices were compared: Brightness Index, Biological Soil Crust Index (BSCI), Crust Index, Enhanced Vegetation Index, Normalised Burn Ratio, Normalised Difference Vegetation Index, Soil Adjusted Vegetation Index and the Stress-related Vegetation Index. The BSCI was found to outperform the other spectral indices in monitoring vegetation cover in this area. Whereas full recovery of vegetation following wildfires in the study area was attained only after 25–30 years, critical thresholds of vegetation cover limiting sand movement were attained after just 1–5 years. The frequency and intensity of wildfires is therefore an important factor controlling dune activity in Australia’s deserts.

Cliff-top dunes are a locally important geomorphic features of sedimentary coasts. They are traditionally interpreted as being sourced by (or with) sand derived from the beach below the cliff. This paper presents the results of a stratigraphic and geochronological study of Carlo Sand Blow, a coastal blowout that has developed on top of a high sandy cliff in the Cooloola Sand Mass, south-east Queensland. We use a combination of sedimentological, pedological and geophysical techniques along with optically stimulated luminescence dating to determine the depositional history and evolution of the blowout. We demonstrate that the blowout is dominantly nourished by sand eroded from its floor rather than the adjacent beach. The original dune surface dates to the first half of the last glacial period (c. 40–70 ka) and this dune was deflated in the late-Holocene. Dune activity is directly associated with cliff undercutting because of coastal retreat in the late-Holocene, but coastal erosion on its own is not capable of maintaining aeolian activity. Blowout activity occurred between 2.6 and 2.3 ka and again at 0.3 ka with aeolian sand burying palaeosols. Both soil surfaces contained charcoal and tree stumps in growth position and our study suggests that fire is the immediate trigger for blowout reactivation. It is likely that these fires were anthropogenic in origin, because the site is somewhat protected from natural fire and the ages coincide with intensification of human use of coastal sites in the area.

ABSTRACTThe effect of fluctuations in temperature and moisture supply on hard seeds of nine tropical coastal sand dune legumes, including herbs (Schrankia atiadrivalvis, Macropiilium atropurpureum and Canavalia rosea), and shrubs (Acacia farncsiana, A. macracantha, Mimosa chaetocarpa, Indigoftra sujjruticosa, Crolalaria incana and Chamaecrista chamaecrutoides), has been studied under laboratory and field conditions. Using a fluctuating temperature gradient bar seeds buried in sand were exposed to various amplitudes of diurnal temperature fluctuation over an extended period of time and seed germinability was examined at intervals. Germination percentage increased considerably in most species as a consequence of treatment with marked effects occurring at temperature fluctuations greater than 20°C and becoming detectable after 45 days. In several species the effect of applying wetting and drying cycles was to lower the amplitude of temperature fluctuation necessary to soften the seeds. Species can be grouped into physiological groups on the basis of differences in seed response to temperature fluctuations. It is suggested that these differences may help to explain the mechanisms distinguishing the different colonization patterns observed in tropical sand dune systems.

There are few freshwater lakes associated with coastal dunes in southern New South Wales (NSW). Lake Nargal near Narooma, Bondi Lake near Bega, and a small lagoon near Pambula have little in common limnologically with coastal dune lakes of northern NSW and southern Queensland. They differ in mode of origin, are less dominated by NaCl, are less acidic, are more speciose, have few characteristic dune-lake indicator species, and moreover contain certain southern species. However, a re-examination of data for Lakes Windermere and McKenzie further north at Jervis Bay suggest that these are classic dune-contact lakes rather similar to those in northern NSW. Differences and similarities are largely influenced by the extent and therefore the hydrological influence of the contextural coastal sand mass and by biogeography.

Smooth Goosefoot (Chenopodium subglabrum) is restricted to North America and reaches its northern distribution limit in Alberta, Saskatchewan and Manitoba. The habitat of Chenopodium subglabrum contains some element of active sand. It is commonly found on the stabilizing edges of active dunes as well as dune blowouts, and occasionally on bare or recently disturbed sand plains. Chenopodium subglabrum is a sexually reproducing annual species with seeds that may remain in the seed bank for several years, waiting for the conditions it favours for germination. Germination of this species is erratic, possibly in response to moisture, making the overall population trend difficult to determine. The estimated population in Canada is likely between 5000 and 10000 individuals. There has been considerable loss of habitat as dunes become vegetated. The processes of dune stabilization and fire control threaten survival of this species.

Abstract. We studied the relationships between crust microstructure, infiltration and water holding capacity under arid and temperate conditions (Factor A: Climate) on biological soil crusts (BSCs) sampled along a~catena on mobile sand dunes (Factor B: Catena). The arid study site was located near Nizzana, Israel (precipitation: 86 mm a−1, PET: ~2500 mm a−1) and the temperate site near Lieberose, Germany (precipitation: 569 mm a−1, PET: ~780 mm a−1). BSCs were sampled near the dune crest, at the centre of the dune slope and at the dune base at each site. Scanning electron microscopy (SEM) was used to characterize BSC morphology and microstructure. Infiltration was determined using microinfiltrometry under controlled moisture conditions in the lab. Water holding capacities were determined after water saturation of the dry BSCs. Wettability of the crusts was characterized using a "repellency index", which was calculated from water and ethanol sorptivities. Irrespective of the climate, an accumulation of fine particles in the BSCs was found, increasing along the catena from dune crest to dune base. Texture was finer and water holding capacities of the underlying substrate were higher at the arid site, whereas surface wettability was reduced at the temperate site. At both sites, BSCs caused extra water holding capacity compared to the substrate. Infiltration rates decreased along the catena and were generally lower at the dune slope and base of the arid site. A mechanism of crust stabilization is proposed where BSCs benefit from increased texture and biomass mediated water supply, and where the water supply to higher plants was limited due to alteration of physico-chemical surface properties under temperate conditions.
