Summary: Dispersal plays a crucial role in the ecological and evolutionary processes of natural populations, with mating behavior being a critical factor shaping dispersal patterns and extents. Our study on the great horseshoe bat revealed a matrilineal population structure but weak nuclear geographic structure, indicating female philopatry and male-biased dispersal. Additionally, a large-scale phylogenetic analysis showed unexpected deep divergence among different regions, suggesting the presence of a cryptic species complex in Rhinolophus ferrumequinum.

Summary: The European Robin Erithacus rubecula is currently considered as a single species with eight subspecies. However, new evidence from molecular, morphometric and bioacoustic data supports the recognition of three separate species within this complex: E. rubecula, E. superbus, and E. marionae. The differences in territorial songs, calls, and wing length between the taxa on Tenerife and Gran Canaria and E. rubecula further support their classification as distinct species. The recognition of the Gran Canaria and Tenerife Robins as separate species adds two single-island endemics to the avifauna of the Canary Islands.

Summary: Knowledge of the genetic structure and cryptic diversity is crucial for the conservation of endangered species. This study examined the genetic survey of Florida bonneted bat populations and revealed distinct genetic differences among different regions. Additionally, mitochondrial DNA analysis suggested the presence of hidden diversity in these bats, indicating the need for reevaluation of their taxonomy.

Summary: Understanding patterns of species distribution and diversity is important for biodiversity conservation. This study conducted a comprehensive bat survey in the Western Ghats region of peninsular India and used maximum entropy modeling to predict the potential distribution of bat species. The study also assessed the level of protection for these bat species across protected area networks in the region.

Summary: Comparative assessment of continuous and event-based hydrologic and water quality models for identifying critical source areas (CSAs) highlights the importance of variable source area (VSA) integration in the models. Results indicate better matching in field CSA potential for sediment and phosphorus with VSA integrated models, particularly in autumn season. Furthermore, qualitative validation suggests slightly better performance of SWAT models compared to AGNPS models, but more detailed field observations are needed for further confirmation.

Summary: Evaluation in environmental education has not been fully utilized. Satisfaction with evaluation processes is low, especially for informal evaluation based on nonsystematic observation and reflection. Emphasizing adaptive management and programmatic improvement in evaluations, as well as addressing gaps in adaptive management and diversity, equity and inclusion efforts, can lead to better quality environmental education.

Summary: Riverbank erosion in Bangladesh is a frequently occurring natural disaster that affects the socio-economic and livelihood status as well as the environment. This study focuses on the Kirtankhola River and assesses erosion, accretion, and channel shifting using satellite imagery and a questionnaire survey. The study highlights anthropogenic factors, such as high waves generated by water vehicles, as the main cause of extensive erosion.

Summary: The study examined the impact of future climate change scenarios on 22 endemic threatened squamates in the Western Ghats, finding that the study species are significantly affected with decreased climatic suitability. Hotspots of species diversity were modeled based on ecological niche models, showing concentration in the North Central and Southern Western Ghats.

Summary: Based on integrated approaches of morphometrics, echolocation call analysis, and molecular phylogenetics, researchers have discovered a new species, Srini's Bent-winged bat Miniopterus srinii, which closely resembles the Small Bent-winged bat Miniopterus pusillus found in other parts of India. Despite external similarities with Miniopterus pusillus from the Nicobar Islands, the new species is relatively larger and distinct in craniodental measurements and echolocation call parameters. Importantly, there is a significant genetic distance of 10.84 +/- 0.22% between Miniopterus srinii and Miniopterus pusillus. The new cryptic species shares distribution with other Miniopterus species in the Western Ghats, emphasizing the importance of studying the genus' cryptic diversity and the region's conservation.

Summary: Insularity provides opportunities for species diversification, but some insects show high morphological diversity with minimal genetic variations. In this study, we used bioacoustics, morphometric and molecular data to evaluate the relationships between the taxa of lesser woolly horseshoe bats in India and Sri Lanka. Our study reveals a close genetic relationship between beddomei and sobrinus with perniger, suggesting that beddomei and sobrinus should be recognized as subspecies of Rhinolophus beddomei.
