Abstract:
... Land use change has been identified as a major driver of amphibian decline around the world. Yet we generally lack an understanding of how conversion to exotic pastures affects freshwater communities. This study examined tadpole assemblages in areas converted to exotic pastures and native wooded grasslands in northern Pantanal wetland, Midwestern Brazil. We tested the differences in site occupancy ...

The relationship between a city's economic development and the ecological resource cost of that development is an important area of research, although the results vary between different study areas and with methods of inquiry. Using spatial match degree and econometric methods, urban economic success, as indicated by GDP and ecological resource base as indicated by vegetation cover (NVDI), for cit ...

Abstract:
... Livestock grazing is the principal land use in arid central Asia, and range degradation is considered a serious problem within much of the high-elevation region of western China termed the Qinghai-Tibetan Plateau (QTP). Rangeland degradation on the QTP is variously attributed to poor livestock management, historical-cultural factors, changing land tenure arrangements or socioeconomic systems, clim ...

Abstract:
... Soil organic carbon (SOC) plays an important role in soil fertility and carbon sequestration, and a better understanding of the spatial patterns of SOC is essential for soil resource management. In this study, we used boosted regression tree (BRT) and random forest (RF) models to map the distribution of topsoil organic carbon content at the northeastern edge of the Tibetan Plateau in China. A set ...

Abstract:
... Reconstructing the evolution of arid landscapes is challenged by limited availability of appropriate environmental archives. A widespread surface feature — stone pavement — traps aeolian fines and forms a special accretionary archive. Seven stone pavement-covered sections on basalt flows in the eastern Mojave Desert are condensed into a composite section, comprising five sedimentological units sup ...

Introduced goats and European rabbits have caused devastating effects on island vegetation, and many successful efforts to eradicate these introduced animals have taken place mainly since the 1950s. Yet, a comprehensive review of vegetation response to goat and rabbit eradications is lacking. We conducted a literature search for articles on vegetation assessments before and after eradications. We ...

Abstract:
... Restoration activities are limited by funding and logistics. To optimise restoration efforts, we need to evaluate the effects of management actions on wildlife populations. In general, site-scale habitat quality has a stronger influence on habitat use by fauna than the landscape context. However, this is yet to be empirically tested for reptiles. In this study, we used model averaging and hierarch ...

However, it is surprising that it is even not easy to find an explicit definition and proper indicator for the term “land use intensity” in the sandy desertification related literatures. To better understand the association between sandy desertification and its driving factors, especial ...

Abstract:
... We show that the system of biocrust and vegetation on sand dunes modeled by two coupled ordinary nonlinear differential equations exhibits self-sustained oscillations. Such oscillations can occur on vegetated linear dunes that are mostly covered by biocrust. The vegetation–biocrust interaction underlies these oscillations and these do not occur if only vegetation dynamics is considered. The oscill ...
