Some animal species shift their activity towards increased nocturnality in disturbed habitats to avoid predominantly diurnal humans. This may alter diel overlap among species, a precondition most predation and competition interactions that structure food webs. Here, using camera trap data from 10 tropical forest landscapes, we find hyperdiverse Southeast Asian wildlife communities peak early mornings intact dawn dusk (increased crepuscularity). Our results indicate anthropogenic disturbances drive opposing behavioural adaptations based on rarity, size feeding guild, with more the 59 rarer specialists' diurnality for medium-sized generalists, less larger hunted species. Species turnover also played role underpinning community- guild-level responses, associated markedly detections of generalists predators. However, predator-prey or competitor guilds does not vary disturbance, suggesting net be conserved.

Anthropogenic activities are increasingly encroaching into wildland areas, heightening interactions between human and carnivore communities. Area-based conservation measures, such as protected areas (PAs), employ different management strategies via land-use designations to mitigate anthropogenic pressures reduce human-wildlife conflicts in shared landscapes. Here, we assessed diel activity temporal overlap around El Triunfo Biosphere Reserve (REBITRI) Chiapas, Mexico, along a designation gradient. We deployed 33 camera traps the gradient, leveraging reserve's core buffer zones, private lands surrounding reserve. calculated species detect changes interspecific competition predator-prey In total, detected 14 carnivores 10 zone, 9 on land across 4777 trap-night survey. Significant shifts single-species zones were for margay (Leopardus wiedii) grey fox (Urocyon cinereoargenteus). Activity was highest zone all pairs, two competitor suggesting reduced niche partitioning this due varied pressures. Our findings contribute assessing PA efficacy understanding multiple-use landscapes where ubiquitous.

ABSTRACT Wildlife often perceives humans as a threat, which can affect their behavioral ecology and alter fitness survival. Studying these responses help to evaluate the impact of human activities. We studied effects presence on anti‐predatory behavior Japanese pika, Ochotona hyperborea yesoensis , small mammal found in rocky montane areas Mount Highashi‐Nupukaushi‐Nupuri, Daisetsuzan National Park, Hokkaido, Japan, during summer season (May August) 2022 2023. compared tolerance or habituation pikas at control site with no interference visitation, where we recorded calling flight initiation distance when approached by researchers. The Spearman correlation coefficient (Shapiro–Wilk test, p < 0.05) indicated significant positive between from trail both ( r = 0.731, 0.001) 0.860, 0.001). Pikas produced significantly higher proportion calls than site. Furthermore, site, repeated encounters reduced distances pikas; that is, were bolder quieter Our research highlights potential increased visitation behavior, highlighting urgency sustainable conservation efforts.

Human-wildlife conflicts pose a growing threat to biodiversity, particularly when the targeted species plays an ecological keystone role. Mauritius has repeatedly mass-culled endemic and threatened flying fox (the Mauritian fox; Pteropus niger ) failing intended objectives of crop protection elevating species’ extinction risks. In this context, ecology should be better understood develop non-lethal management strategies. Here we investigated foraging patterns vertebrate frugivores over 24 hour cycles in lychee orchards backyard gardens. We assessed all agents damage (mainly fox, alien bird, mammal) temporal variation bird (take amount eaten relative fruit ripeness) on trees. The most important lychees were foxes (78.3%) birds (16.1%), namely ring-necked parakeets ( Alexandrinus krameri ), red-whiskered bulbuls Pycnonotus jocosus village weavers Ploceus cucullatus common mynas Acridotheres tristis while by mammals was negligible (<1%). Flying consumed more fruits early night (59%) compared late statistically significant one orchard backyards. However, difference average three per tree night. Bird at both highest during first half day (64%). ate fewer towards end fruiting season followed opposite trend. As ripeness increased from unripe fully ripe, 39–42% pulp two orchards. Parakeets 7% with increasing only. Deliberate disturbances involving smoke, noise or light deter weak extent between suggested best minor advantages concentrating deliberate night, that netting would strategy as it also protect against diurnal frugivores. Additionally, trees protected sixth week after set occurred unripe. Such improved timing play role reducing losses thereby alleviate human-wildlife conflict around fox’s diet.

Abstract Intact native forests under negligible large-scale human pressures (i.e. high-integrity forests) are critical for biodiversity conservation. However, declining worldwide due to deforestation and forest degradation. Recognizing the importance of ecosystems (including forests), Kunming-Montreal Global Biodiversity Framework (GBF) has directly included maintenance restoration ecosystem integrity, in addition extent, its goals targets. Yet, headline indicators identified help nations monitor their integrity can currently track changes only (1) cover or (2) risk collapse using IUCN Red List Ecosystems (RLE). These unlikely facilitate monitoring two reasons. First, focusing on not misses impacts anthropogenic degradation but also fail detect effect positive management actions enhancing integrity. Second, as measured by ordinal RLE index (from Least Concern Critically Endangered) makes it that continuum over space time would be reported nations. Importantly, many biodiverse African Asian remain unassessed with RLE. As such, will likely resort alone therefore inadequately report progress against We concur indeed vital aspects conservation monitoring. they insufficient specific purpose tracking crucial components GBF’s goals. discuss pitfalls merely cover, a outcome current indicators.
