Summary: This study in the Western Ghats mountains of peninsular India found that restoring degraded forests through diverse native tree species planting, controlling invasive alien species, and increasing canopy cover can benefit rainforest recovery. However, planting non-native monocultures in degraded forests may have counterproductive effects on long-term forest recovery.

Summary: This study used passive acoustic monitoring to assess the response of vocalizing fauna and birds to ecological restoration. The results showed that different taxa have varied responses to habitat recovery, emphasizing the importance of a multi-taxon approach in assessing restoration programs.

Summary: The study assessed restoration success in a quarry undergoing restoration practices for 40 years, finding that bird abundance in the restored area was significantly lower and the bird community composition differed from neighboring natural and semi-natural areas. Vegetation characteristics, such as native vegetation cover and fruit richness, played a key role in driving bird community composition and influencing seed dispersal services.

Summary: This study determines the probable habitat distribution range of the narrowly endemic species Gluta travancorica using ecological niche modelling. The results show that the deep neural networks (DNN) model has exceptional prediction performance. The study has important implications for conservation and restoration strategies of the habitat of G. travancorica and regional biodiversity conservation.

Summary: Coastal wetland restoration can help prevent the loss of ecosystem functions, but its impact on bird diversity is uncertain. This study used a newly restored wetland as an example to investigate the effects of coastal restoration on bird diversity. The results showed that the restored wetland attracted a total of 70 bird species, with passeriformes and waterbirds being the main species.

Summary: This study aims to evaluate the habitat occupancy pattern of large mammals across a gradient of anthropogenic pressures. Through ecological sign surveys in Tamil Nadu, India, the study examined the effects of ecological and anthropogenic variables on the occupancy of tiger, leopard, dhole, elephant, and gaur. The results showed that the occupancy of large mammals was influenced by prey abundance, habitat features, direct human disturbance, and habitat fragmentation. Tigers and dholes were driven by the abundance of large and medium-sized prey, while leopards also relied on small prey species and fragmented forest patches.

Summary: The decline of farmland bird populations since the 1980s has led to extensive research on farmland biodiversity conservation in Europe. However, surprisingly, there has been no direct focus on farmland birds in the landscape-scale restoration of grassland ecosystems on former croplands. Through a comparative study, it was found that grassland restoration positively influenced farmland bird species richness and diversity, while extensive cropland cultivation only increased species richness. Such findings suggest that landscape-scale grassland restoration can be an effective tool in reversing regional farmland bird declines and conserving farmland biodiversity.

Summary: The construction of the Three Gorges Dam Project has negatively impacted the forest landscapes and bird diversity in the Three Gorges Reservoir (TGR) area. Although the government has implemented ecological projects to restore the forest, the fragmentation of forest landscapes in the TGR area has not been effectively improved. This study found that increasing forest amount directly enhances bird diversity in all guilds, while fragmentation indirectly reduces diversity in vertical-profile generalists and understory birds through vegetation condition.

Summary: Different approaches were used to assess restoration treatments and varied in the amount of acoustic data incorporated and human processing time. The study found that relying only on visual and acoustic review may fail to capture diel acoustic patterns identified in other approaches.

Summary: Landscape changes due to habitat loss and fragmentation can result in complex changes in biodiversity and functional diversity, affecting resource use and species interactions. In this study, the impact of habitat loss on the functional diversity of bird communities was assessed in the Bahia Atlantic Forest. Results showed a decrease in resource use and structural complexity, as well as functional dissimilarity between species, in landscapes with low forest cover. The study highlights the importance of forests in supporting species and their functions, and provides indicators for conservation actions to preserve the Atlantic Forest.

Summary: The study found that rainforest specialist species decreased in number and diversity with increasing habitat simplification, while forest generalist species were relatively unaffected. Pastures were mainly dominated by bird species typical of grassland, wetland, and open eucalypt forest habitats, with pasture trees playing a modest role in enhancing local bird communities. Overall, even small scattered patches of mature and regrowth forest contributed significantly to local bird diversity in the landscape.

Summary: Due to the rapid urbanization in China, the urban ecological system has become fragmented and poses a threat to stability. Constructing ecological networks is seen as a crucial strategy to restore ecosystems. This research developed a GIS-based model to guide urban ecological network construction and identify priority areas for protection. The model was tested in Wujiang District, Suzhou, and identified key ecological patches, corridors, nodes, and barriers. Based on these findings, the study proposed recommendations for restoration and protection strategies in accordance with existing territorial and spatial planning.

Summary: This study provides a comprehensive assessment of the extirpation of threatened birds in Australia by mapping their past and current potential habitats. The results indicate a significant loss of habitat and range contraction for these species, with some having been extirpated from the majority of their former potential habitat.

Summary: The Nilgiri tahr, an endangered mountain ungulate endemic to the Western Ghats of India, faces threats from habitat fragmentation, hunting, and a limited range. A recent survey in the Anamalai Tiger Reserve suggests that the population of this species is stable in this protected area, which harbors 20-25% of the global population of the Nilgiri tahr.

Summary: The study conducted monthly surveys of Great Hornbills and Malabar Grey Hornbills in shade-coffee plantations and continuous rainforests over 15 months. While both hornbill species were found to use the habitats year-round, density estimates were higher in the protected area, especially during nesting seasons. Male bias in the sex ratio of observed adult birds during the nesting season indicated a higher proportion of breeding pairs in the protected area compared to plantations.

Summary: This study examines the impact of habitat structure on the presence and clustering of mixed-species flocks of birds. It finds that flocks prefer areas with lower tree density and a complex foliage structure. Additionally, it suggests that intraspecifically gregarious species may play a strong role in habitat selection within flocks.

Summary: Research in the Western Ghats of India showed that organic tea plantations are better for birds compared to conventional tea plantations, and mixed-shade tea plantations are even more beneficial, though still not as good as forests. Retaining or promoting native shade trees in tea plantations can increase bird diversity and abundance, supporting landscape-level bird conservation efforts.
