Published: Feb. 24, 2025

This study explores the plant-pollinator network in district Doda, Jammu & Kashmir, India, a Himalayan region with limited research on biodiversity and pollination ecology. Pollinators like bees, butterflies, beetles are vital for ecosystem health agricultural productivity, yet Doda lacks comprehensive data its pollinator species interactions, unlike Kashmir Valley region. Drawing insights from similar regions such as Himachal Pradesh, Uttarakhand, this highlights ecological role of pollinators emphasizes need extensive field exploration Doda. The advocates an interdisciplinary approach combining ecological, agricultural, local knowledge, recommending detailed surveys, long-term monitoring, socio-economic studies to understand pollination’s impact agriculture. It calls collaborative efforts among researchers, departments, conservationists gather baseline data, promote preservation, enhance sustainability.

Impact of soil physicochemical factors and heavy metals on co-occurrence pattern of bacterial in rural simple garbage dumping site

Ecotoxicology and Environmental Safety, Journal Year: 2024, Volume and Issue: 280, P. 116476 - 116476

Published: May 31, 2024

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.

Plant-pollinator interactions along the altitudinal gradient in Berberis lycium royle: An endangered medicinal plant of the Himalayan region

PLoS ONE, Journal Year: 2025, Volume and Issue: 20(5), P. e0310572 - e0310572

Published: May 7, 2025

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.

Cuticular Hydrocarbon Profiles of Himalayan Bumble Bees (Hymenoptera: Bombus Latreille) are Species-Specific and Show Elevational Variation

Journal of Chemical Ecology, Journal Year: 2024, Volume and Issue: unknown

Published: March 12, 2024

Abstract Bumble bees are important pollinators in natural environments and agricultural farmlands, they particular adapted to harsh like high mountain habitats. 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 7,000 m, shaping a diverse floral faunal community at different elevational zones. To identify possible adaptation strategies, we investigated cuticular hydrocarbon profiles four bumble bee species occurring Arunachal Pradesh, northeastern most state India. At 17 locations along an gradient, collected workers two from lower elevations ( B. albopleuralis breviceps; ~ 100 m − 3,000 asl) higher prshewalskyi mirus ; 2,800 4,500 asl). CHC all showed significant degree variation composition hydrocarbons, indicating specificity. We also found clear correlation elevation. weighted mean chain length hydrocarbons significantly differed between elevation species, proportion saturated increased range species. Our results indicate that living reduce water loss by adapting their on cuticle, phenomenon has been other insects ants fruit flies.

Aggressive dominance of acacia floral resources by wild east African lowland honey bees

African Journal of Ecology, Journal Year: 2024, Volume and Issue: 62(2)

Published: Feb. 1, 2024

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. We suggest protection should emphasised active conservation agendas India.
