Summary: This study used camera trap videos to document wildlife biodiversity and animal activities at several large wood complexes in Rock Creek, Oregon. The results showed that large wood plays an important role in supporting wildlife biodiversity and providing habitat connectivity between terrestrial and aquatic environments. The study also highlighted the variability in the effects of large wood across different stream locations.

Summary: China's Green Space System Planning research has expanded to municipal and provincial scales and focused on the role of green space in the water environment. The study of green corridors often lacks hydrological data, especially in large scales, and mainly concentrates on central urban areas. Using Fujian province as an example, this paper identified blue and green corridors based on DEM and land use data, and proposed planning suggestions for ecological networks and nodes.

Summary: The study aims to identify extreme climate refugia for wild cacao in Colombia and assess threats caused by deforestation in the Amazon region. Findings suggest that even small changes in extreme precipitation over just 30 years have led to a decrease in suitable habitat for wild cacao.

Summary: Climate projections suggest that temperature will increase and precipitation will decrease in Castilla y Leon in the near future, which may lead to a reduction in hydrographic networks and threaten the survival of various wild species. Flow variations in the networks were determined based on climate modelling, indicating a decrease in flow accumulation. The analysis of ecological connectivity using Morphological Spatial Pattern Analysis and Probability of Connectivity index showed a significant loss of connectivity and increased fragmentation of riparian habitats in the future.

Summary: This study develops a repeatable indicator for measuring the capacity of landscapes to retain biodiversity under different climate conditions. An Australian case study shows significant regional variations in biodiversity retention, depending on climate change rate, landscape heterogeneity, and anthropogenic impacts.

Summary: Ecological corridors are important for preserving biodiversity in human-impacted areas. This study developed a framework to prioritize the protection and construction of corridors based on landscape similarity assessment. Using Nanjing Metropolitan Area as a case, ecological sources were identified and connectivity was assessed using different methods. The results showed that 58 ecological sources were potentially connected by 103 corridors. Classification and prioritization of corridors were based on the precedence matrix method.

Summary: Recent studies have shown that habitat fragmentation caused by road infrastructure development, urbanization, and land-use changes has negative environmental effects and leads to biodiversity loss. This study focuses on developing a methodology to identify ecological corridors for brown bears in the Romanian Carpathian Mountains, emphasizing the cautious implementation of ecological corridors in planning practice and the importance of field data in research.

Summary: The Amazon Basin is home to a vast network of healthy, free-flowing rivers that support a rich diversity of freshwater species. However, the construction of dams and other infrastructure poses a threat to the integrity of these rivers, disrupting connectivity and altering important habitat and ecosystem functions.

Summary: Increasing landscape connecting elements cannot compensate for large-scale grassland area loss, leading to significant declines in both structural and functional connectivity. Generalist species are negatively affected by connectivity, with structural connectivity having the strongest impact, while functional connectivity determines the presence of grassland specialist species in focal grasslands.

Summary: Habitat fragmentation and isolation are significant factors contributing to biodiversity loss in cultural landscapes. Linear ecological corridors are proposed as a solution to facilitate plant dispersal and connect isolated habitats, but they may also bring risks of spreading invasive species.

Summary: The study demonstrates that livestock trails play a crucial role in reducing fragmentation of pasturelands, providing effective corridors for the movement of organisms. MSPA analysis allows for pixel-level classification of landscape typologies and mapping of corridor structures on a continental scale. The research highlights the importance of conducting connectivity analysis at different times of the year to understand the evolution of connectivity and optimize wildlife and livestock management.

Summary: Ensuring connectivity between rural and urban areas is crucial for nature protection. In this study conducted in Cochabamba, Bolivia, we examined the effectiveness of artificial green corridors for bird populations. Comparing natural corridors with preserved vegetation and artificial corridors consisting of parks and gardens, we found that green corridors supported more common and heavier bird species with lower beak depth/mass, while urban noise had a significant impact on species composition. Our findings suggest that green corridors can effectively maintain bird populations, although noise remains a limiting factor for both types of corridors.

Summary: The study found that movement corridors used by animals and high road mortality are not spatially associated. Road segments where both methods agree should be prioritized for mitigation for five species of felids in Brazil.

Summary: Building urban ecological corridors and enhancing their functional connectivity are essential for biodiversity conservation and ecosystem services in urbanized areas. However, the key spatial indicators that affect the functional connectivity of these corridors are unclear, leading to ineffective optimization measures. This study aims to reveal the quantitative relationship between the spatial structure and functional connectivity of urban ecological corridors, using Minhang District, Shanghai, as a representative area. It identifies the spatial boundaries of ecological corridors, measures their functional connectivity, and identifies the spatial structural factors that contribute to their variation. The results provide insights for improving the functional connectivity of urban ecological corridors and optimizing their design.
