Network Assemblages of Elevational Niche‐Associated Diversity in Fijian Native Bees

Ecology and Evolution, Journal Year: 2025, Volume and Issue: 15(3)

Published: March 1, 2025

Species assemblages constrained by ecological and evolutionary processes (and the interactions between them) are vulnerable to changes in their environment. Network analyses do not explicitly build phylogenetic histories when exploring how they assembled, yet can be a critical source of information for understanding species may incorporated into webs. Recent studies have revealed unexpected diversity monophyletic clade native Fijian bees subgenus Lasioglossum (Homalictus). These undergone remarkable recent radiation with evidence conservatism elevational niches physiological traits. Here we use bipartite network analyses, as an adjunct further inform likely ancestral elevations these explore patterns occupied other niches. Our approach is novel that categorize elevation bands then treated lower hierarchical level onto which map individual bee species. support earlier inferences highland (or climates correspond barriers occupation significant.

Range-wide camera traps reveal potential prey species for Javan leopards

Global Ecology and Conservation, Journal Year: 2024, Volume and Issue: 53, P. e03020 - e03020

Published: June 9, 2024

Prey depletion poses a threat to large carnivores worldwide. The Javan leopard (Panthera pardus melas), the last remaining apex predator on Indonesian island of Java, is facing numerous threats from human activities including poaching, habitat loss and prey depletion. Despite fact that an adaptable opportunistic capable surviving in various environments, our understanding its predator-prey interactions still limited, which crucial for their conservation. Using camera trap data collected four national parks (i.e., Ujung Kulon, Gunung Gede Pangrango, Meru Betiri, Alas Purwo) represent distinct terrestrial ecoregions across we investigated species richness, relative abundance, spatial-temporal overlap activity patterns between other animals coexist same location. Our analysis 7461 independent photos, covering 12,983 days, revealed areas with presence leopards exhibited higher richness abundance compared those without leopards. In addition, found banteng (Bos javanicus), barking deer (Muntiacus muntjak), (Rusa timorensis), mousedeer (Tragulus wild boar (Sus scrofa), junglefowl (Gallus spp.), spangled ebony langur (Trachypithecus auratus), rhino (Rhinoceros sondaicus), long-tailed macaque (Macaca fascicularis) dhole (Cuon alpinus) were highly overlapping space time, suggesting these are potential candidate To knowledge, this first comprehensive investigation utilizes traps all types Java Island. findings study may serve as essential information conservation critically endangered species.

Cat–wildlife interactions and zoonotic disease risk: a call for more and better community science data

Mammal Review, Journal Year: 2023, Volume and Issue: 54(2), P. 93 - 104

Published: Dec. 1, 2023

Abstract Due to their close interaction with both wildlife and humans, free‐ranging domestic animals are well‐suited act as conveyors of zoonotic pathogens. Yet, although cats Felis catus major predators bats other groups concern (e.g., rodents birds), mounting evidence suggests that role in the emergence diseases may be unappreciated. Here, we use bat–cat information extracted from popular iNaturalist platform a case point illustrate potential community science social media expand our understanding pet‐wildlife interactions. Although observations preying on were more prevalent Europe North America, such interactions was documented across different geographic regions, revealing relatively high incidence bat predation by providing cat–bat previously unreported scientific literature. The lack surveillance focused pets bridging hosts for spillover events is concerning, considering recognised risks they pose. Community untapped source relevance. It crucial gain better between understand contribution past future disease outbreaks. Failing do so not only jeopardises human health but also puts at risk.

Diel activity of insectivorous bats in response to land-use change in São Tomé Island, Gulf of Guinea

Research Square (Research Square), Journal Year: 2024, Volume and Issue: unknown

Published: May 29, 2024

Land-use change poses a significant threat to biodiversity, particularly in insular ecosystems where species exhibit higher levels of specialisation. Despite the importance tropical islands for biodiversity conservation, impacts land-use on diel activity remain poorly understood. We addressed this gap by investigating patterns insectivorous bats response São Tomé Island, Central West Africa. Using passive acoustic detectors, we surveyed across forests, shaded plantations, oil palm agricultural and urban areas. examined (1) how intraspecific varies between forest human-altered types, (2) interspecific within same type, quantifying overlap coefficients activity. Based 19,383 bat passes from four species, found that degree species-specific forests types varied with least being observed areas Miniopterus newtoni, plantations Chaerephon spp.. Overlap different was lower less or not disturbed (forests plantations), more were present. Overall, altered according magnitude structural change. Such responses might be eventually due temporal prey availability competition types. These findings comprise baseline knowledge informing evidence-based management actions island systems.
