In these environments, animals exposed low temperature face the risk of desiccation. The Eastern Himalayas one recognized biodiversity hotspots worldwide. area covers subtropical rainforest with warm precipitation as well ranges peaks reaching up 6000 m, shaping a diverse floral faunal community at different altitudinal zones. We investigated cuticular hydrocarbon profiles four bumble bee species occurring elevational Arunachal Pradesh, northeast most state India. At 17 locations along an gradient we collected workers two from lower elevations ( B. albopleuralis breviceps; ∼ 100m - 3000m asl) higher prshewalskyi mirus ; 2800m 4,500m asl). CHC all showed significant degree variation composition hydrocarbons, indicating specificity. also found clear correlation elevation. weighted mean chain length hydrocarbons significantly differed between species, proportion saturated increased range species. Thus, eastern seem adapt their elevation by decreasing water permeability cuticle, similar insects living dry mountains or deserts

Rural waste accumulation leads to heavy metal soil pollution, impacting microbial communities. However, knowledge gaps exist regarding the distribution and occurrence patterns of bacterial communities in multi-metal contaminated profiles. In this study, high-throughput 16 S rRNA gene sequencing technology was used explore response various pollution rural simple dumps karst areas Southwest China. The study selected three habitats center, edge, uncontaminated dump evaluate main factors driving change community composition. Pollution indices reveal severe contamination across all elements, except for moderately polluted lead (Pb); severity ranks as follows: Mn > Cd Zn Cr Sb V Cu As Pb. Proteobacteria, Actinobacteria, Chloroflexi, Acidobacteriota predominate, collectively constituting over 60% relative abundance. Analysis Chao Shannon demonstrated that center boasted greatest richness diversity. Correlation data indicated a predominant synergistic interaction among landfill's community, with higher number positive associations (76.4%) compared negative ones (26.3%). Network complexity minimal at dump's edge. RDA analysis showed Pb(explained:46%) Mn(explained:21%) were key causing difference composition edge area dump, AK(explained:42.1%) Cd(explained:35.2%) dump. This provides important information understanding patterns, co-occurrence networks, environmental mechanisms landfill soils under stress, which helps guide formulation treatment remediation strategies.

The terrestrial ecosystem, particularly mountain regions, influences species distribution by providing diverse climatic conditions that vary with rising altitude. These factors play a significant role in determining phenology and niche width. However, the environmental influencing pollination dynamics of specific plant across altitudes remain unexplored. Considering gaps, we assess how composition abundance pollinator fauna associated important medicinal Berberis lycium Royle (Berberidaceae) five distinct altitudinal gradients (800–2200 m) Pir-Panjal range northwestern part Indian Himalayan region. Pollinators, including bees, butterflies, wasps, flies were monitored over two consecutive flowering seasons (2022–2023). A total 39 insect representing orders 17 families, recorded visiting B. during its period range. linear regression model indicated all four indices exhibited declining trend increasing altitude when data pooled together. only foraging speed (FS) index rate (IVR) showed declines. Among individual groups, Lepidoptera displayed relationship altitude, while other groups asynchrony along gradient. Furthermore, reproductive output (fruit seed production) declined significantly Our findings suggest but also differentially shapes plant-pollinator interactions, behaviour, success. This study highlights importance monitoring interactions fragile where changes could have cascading effects on ecological stability.

Abstract The East African lowland honey bee ( Apis mellifera scutellata ) is reported as an aggressive subspecies of the Western bee, but few studies have investigated impact its aggressiveness on other insect pollinators. Observations flower visitors to Vachellia Acacia etbaica and interactions between bees insects were conducted in 2022 Mpala, Kenya. A total 873 individual recorded, most frequent being Hymenoptera, followed by Diptera Lepidoptera. Honey dominated floral resources morning late afternoon. When encountered types insects, they displaced latter from flowers 100% time. This has never been observed subspecies, we recommend further research these taxa.

Abstract Animal pollinators underpin the functioning and persistence of ecosystems globally. However, vital role pollination is being progressively eroded by worldwide decline pollinator species caused human-induced environmental degradation, resulting in rising costs to biodiversity, agriculture, economy. Most studies quantifying diversity declines have focused on insects, whereas vertebrate remain comparatively neglected. Here, we present first comprehensive study macroecological patterns richness extinction risk bird mammal India, a region extremely high biodiversity increasing anthropogenic pressure. Our results reveal that hotspots are restricted south Western Ghats, scattered throughout country. Analyses threatened (based IUCN Red List) show only currently classified as multiple population were observed for birds, primarily Southwest pollinators. analyses failed identify traits drivers these patterns, most appear be logging hunting food, medicinal purposes. Pollinator endangerment has widescale ecological economic implications such reduced food production, plant extinction, loss functional genetic diversity, damage.
