Eurasian Black Vulture (EBV) and Eurasian Griffon Vulture (EGV), while residents elsewhere, winter in Uttar Pradesh, India. Knowledge of the habitat and regulating factors is obligatory for protection and better management of these vultures. Therefore, different types of habitats were mapped using eight species distribution models. Presence records from field survey, published data and citizen science, and 23 bioenvironmental raster layers were the model inputs. Eighteen models were developed whose strength varied greatly. As per the performance indicators, GBM and GLM were found to be superior models for EGV. For EBV all models were acceptable. MARS, with good model strength, was rejected on the grounds of field verification. However, the Ensemble model, overall, was found the best. As per this model, good habitat was restricted mostly in the Tarai ecozone. The top two vital variables were NDVI, and bio13 for both the vultures. The most vital temperature variable for EGV was bio08 while bio09 for EBV. Tarai ecozone showed the largest expanse of suitable area for both the vultures followed by Vindhyan-Bundelkhand, Gangetic plains and Semi-arid ecozones. Among the two, EBV (49000 km2) had more suitable area than EGV (37000 km2). Agricultural areas were found to be largely unsuitable. As per land cover, good habitat was mostly confined in forests. For better management of these wintering vultures which need only roosting and foraging, it is proposed that destruction of forested habitat and decrease in foraging materials needed immediate attention and control.
Butterflies are more elegant and appealing than most insects, they are included in the order Lepidoptera. They are varied in shape, size and colour. They are found everywhere throughout the world apart from the poles. The present study aims to provide a baseline for the analysis of population status of butterfly species and their dispersion in Lucknow region. The butterfly individuals were collected randomly for twelve consecutive months, August 2021 to July 2022. The butterfly data was collected by using the photographic evidences, capture and release method as well as by visual observations. The butterfly diversity was determined to quantify the values of Shannon diversity index (H) and Simpson diversity index (D). Notably, 40 species of butterfly of 5 families and number of individuals of each species were monthly recorded during the entire period. Overall, this site showed higher diversity of butterfly species. In this region, the Shannon-Weiner diversity index (H) and Simpson diversity index (D) were measured 3.652 and 0.974, respectively. The identified butterflies in the campus are from families Nymphalidae (20 species), Pieridae (8 species), Hesperiidae (5 species), Lycanidae (4 species) and Paplionidae (3 species). The findings showed a marked diversified pattern of butterfly species. This may be attributed to the more diverse habitats in Lucknow region.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
