Summary: The study reveals the population size and distribution of black-necked cranes in the Shaluli Mountains. It predicts the impact of climate change on their distribution and habitat quality. The results show an estimated population of about 200 cranes, mainly distributed in gentle meadows and wetland habitats along the lake. Climate change is expected to increase the suitable habitat area and shift the distribution towards the northwest and higher elevation. Long-term monitoring and conservation efforts are recommended to protect the black-necked crane population and wetland resources in the region.

Summary: Heavy metal contamination poses a significant environmental threat to wildlife. This study constructed an optimized health risk assessment model and applied a pollution allocation factor to accurately assess the risk of heavy metal exposure to wildlife. The model was applied to assess the exposure risk of heavy metals for black-necked cranes and identified the highest risk elements. It can serve as a useful tool for the conservation and habitat quality improvement of black-necked cranes and other waterbirds.

Summary: Studies on the migration patterns, habitat use, and conservation of the Eastern common crane Grus grus lilfordi in East Asia are insufficient. This study explores the migration pattern, habitat use, and conservation status of the Eastern common crane. The cranes migrated an average of 1581.5 km in autumn and 1446.5 km in spring between their breeding site in Eastern Mongolia and the following wintering sites.

Summary: The spatial distribution of dominant woody species in secondary evergreen broad-leaved forests is affected by habitat heterogeneity and negative density dependence. Different species have formed unique spatial structures due to their habitat preferences, but are generally subjected to density-dependent effects.

Summary: Using satellite telemetry data, this study revealed the diverse migration routes of black-necked cranes, including migration orientations, spatial-temporal patterns, and altitudinal movement patterns. The study also identified long-term and short-term stopover sites. These findings contribute to the understanding of critical habitats and connectivity among breeding colonies, supporting the development of effective seasonal conservation plans.

Summary: In the Kinabatangan floodplain, the expansion of oil palm plantations and human settlements has resulted in the reduction and fragmentation of the lowland tropical forests, affecting the behavior of the endangered Bornean elephants. While female elephants exhibit a high fidelity to forests, male elephants and some females heavily use oil palm estates.

Summary: This study aimed to describe the spatial ecology of red deer in Mediterranean ecosystems of South-Central Spain, showing that red deer exhibited less activity, a shorter daily range, and a smaller home range during the food shortage period. In different land use types, individuals in fenced hunting estates showed the lowest activity and daily range.

Summary: This study developed a spatially explicit metacommunity model to investigate species coexistence in fragmented heterogeneous landscapes. By parameterizing the model with Bayesian approach and analyzing a time-series dataset, the study revealed the interspecific variation in extinction and recolonization processes and their dependencies on habitat size and environmental temperature. This interspecific variation contributes to species coexistence by reducing fitness differences and increasing niche differences.

Summary: This study used ecological niche models to predict future habitat for the whooping crane along the US Gulf Coast and analyzed the factors influencing crane presence and the impact of sea level rise on the habitat. The results indicate that emergent herbaceous wetland and water are the most important variables for crane presence.

Summary: With the increase in aquaculture food production, introduced aquaculture species are important in meeting the rising demand for aquatic food products and contributing to societal benefits. The coexistence of Japanese smelt and sharpbelly in Lake Bosten is mediated by habitat segregation, with sharpbelly often dwelling near the shore and Japanese smelt prefering pelagic waters. Water temperature is the main driver of this spatial segregation and coexistence, along with factors such as spawning, food resources, and fishing. These results provide new insights into niche partitioning patterns and the avoidance of resource competition through spatial habitat segregation.

Summary: Cities have an impact on the distribution of bird species, with threatened bird hotspots overlapping greatly with urbanized areas, where only a small percentage of preferred land cover is found. While green infrastructure can improve local bird diversity, the homogeneity of urban environments results in similar species compositions across regions. Narrow-range species should be prioritized in biodiversity conservation strategies, and global coordination of conservation actions among cities is necessary.

Summary: The gut microbiota of black-necked cranes undergo changes during overwintering, with higher diversity in early winter compared to late winter, and a significant increase in abundance of Bacteroidota. This study provides basic data for understanding the environmental adaptation mechanism of black-necked cranes.

Summary: Contrary to previous studies suggesting strong spatial avoidance of lions by wild dogs, the primary lion-avoidance strategy of wild dogs was found to be selecting landscape features that aid in avoiding lion detection in this new study. This habitat selection by wild dogs was commonly used, especially in areas and during times of high lion-encounter risk, indicating a proactive response to lion risk. The findings suggest that spatial landscape heterogeneity could provide an alternative mechanism for carnivore coexistence, especially as shrinking carnivore ranges lead to increased contact between inferior competitors and dominant species.

Summary: The study found niche expansion in non-native populations of the Asian openbill, primarily due to the tolerance of colder and wetter environments, with potential distribution concentrated on equatorial islands. Recommendations include considering source populations when analyzing alien species and further application of the tolerance niche concept, as well as the need for standard measurement frameworks for analyzing the tolerance niche.
