County-level cropland fragmentation in China (1990–2023)
Cropland fragmentation (CLF) studies often overlook bidirectional land transformations. This study reassesses county-level CLF in China (1990–2023) using a 30 m-resolution Landsat-based dataset and a novel Modified Landscape Division Index to capture both cropland gains (transfer-in) and losses (transfer-out). We find pronounced CLF increases in urbanized plains, notably the Huang–Huai–Hai Plain (6.13 × 10 −2 y), Northeast China Plain (3.69 × 10 …
Distribution, Population Density, and Behavior of Dwarf Galagos (Paragalago sp.) in Taita Hills, Kenya
A good understanding of taxonomy, distribution, and population density is needed for conservation. Scientific knowledge of dwarf galagos ( Paragalago sp.) remains limited. Two populations of Taita dwarf galagos survive in the largest remnants of moist montane forest in Taita Hills, Kenya. We obtained acoustic data on the two remaining populations using AudioMoths—small, passive recorders—more than 231 h in January and February 2021. We measured f…
Intensification of the dispersion of the global climatic landscape and its potential as a new climate change indicator
Increases and decreases in the areas of climatic types have become one of the most important responses to climate warming. However, few attempts have been made to quantify the complementary relationship between different climate types or to further assess changes in the spatial morphology. In this study, we used different observed datasets to reveal a dispersion phenomenon between major global climate types in 1950–2010, which is significantly co…
Views from two mountains
African mountains are characterized by high levels of biodiversity and provide ecosystem services to millions of people. Due to steep environmental gradients, growing human populations and geographical isolation, these coupled socio-ecological systems are highly vulnerable to climate change impacts. The capacity of local stakeholders to anticipate future changes and to assess their potential impacts is paramount for enhancing adaptation and resil…
