In Peru, insectivorous bats remain poorly studied, particularly in high-elevation rainforest ecosystems of the upper Amazon region. This study used passive acoustic sampling to examine the nocturnal activity patterns of insectivorous bats in the Cordillera Escalera Regional Conservation Area, San Martín, Peru, during the wet and dry seasons of 2024. We evaluated activity and hourly activity patterns at both community and species levels to assess seasonal variation in temporal behavior. Ten insectivorous bat species were recorded. Overall bat activity was substantially higher during the wet season than the dry season, with some variation in species-specific responses. High-flying species exhibited increased activity during the wet season, whereas low-flying species maintained or intensified their activity during the dry season. The wet season was characterized by higher temporal synchrony, whereas the dry season was characterized by greater temporal partitioning. Most species exhibited unimodal activity patterns that peaked early at night, but some species displayed bimodal patterns, suggesting temporal segregation related to foraging strategies and habitat structure. This study represents the first assessment of hourly activity patterns of insectivorous bats in the upper Amazon montane rainforests and establishes a baseline for long-term acoustic sampling aimed at understanding how seasonal and environmental variability shape bat temporal niches.","PeriodicalId":8982,"journal":{"name":"Biotropica","volume":"58 5","pages":""},"PeriodicalIF":1.9,"publicationDate":"2026-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/btp.70261","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148994491","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Field surveys were conducted over three reproductive periods (2018–2021) in 12 permanent ponds using individual photo-identification. Pond depth was the main driver of adult emigration. The percentage of arboreal/shrubby edge vegetation was the strongest predictor of immigration and individual abundance.

To address this knowledge gap, we analyzed dung beetle diversity, community composition, and beta diversity across an urbanization gradient from forested areas to managed urban parks in Singapore, a Southeast Asian city. To comprehensively assess the dung beetle communities, we deployed flight interception traps and pitfall traps with varying bait types at 12 sites across the gradient. We found a decline in dung beetle richness and diversity, with changes in community composition and high species turnover with increasing urbanization. Forest-restricted species, including the ecologically important large nocturnal tunneller, Catharsius cf. renaudpauliani and Singapore's only rolling species, Paragymnopleurus maurus, were found in less urbanized sites, while disturbance-tolerant species predominated in more urbanized sites. Flight interception traps and human dung-baited pitfall traps captured distinct dung beetle assemblages, highlighting their complementary value. Importantly, our findings demonstrate that Singapore's remaining forests are vital in sustaining populations of forest-associated dung beetles and the ecological functions they provide. This study establishes a useful baseline for monitoring the future impacts of urbanization and the effectiveness of Singapore's ongoing greening efforts and naturalizing of urban areas.","PeriodicalId":8982,"journal":{"name":"Biotropica","volume":"58 5","pages":""},"PeriodicalIF":1.9,"publicationDate":"2026-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/btp.70256","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148942292","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our hypothesis is that there is a dominance of exotic species used in the landscaping of squares, which promotes biotic homogenization, driven by cultural and aesthetic preferences. We believe that larger and older squares have less dominance and greater species diversity. This study investigated the composition, diversity, and representativeness of Amazonian flora across 35 public squares in Manaus, Central Amazonia. We recorded all specimens with a diameter at breast height (DBH) ≥ 5 cm. We recorded 1218 individuals from 88 species and 31 families. Species origin was classified by biogeographic region, with only Amazonian taxa considered native. Exotic species predominated (61.4%). Notably, 15 exotic species with invasive potential were identified, posing significant risks to local biodiversity. We tested the influence of square area and age on community structure. Area was the sole significant predictor of richness, whereas larger and older squares exhibited higher dominance by a few species, such as Mangifera indica (mango) and Moquilea tomentosa (oitizeiro). Age was the only significant negative predictor of alpha diversity. Beta diversity was not influenced by any predictor, indicating a highly homogenized species pool. Urgent management actions are needed that consider both individual squares and the broader landscape to gradually replace exotic and invasive species with native Amazonian species while aligning with the preferences of local residents, thereby restoring ecological functions and enhancing the conservation of urban forests.","PeriodicalId":8982,"journal":{"name":"Biotropica","volume":"58 5","pages":""},"PeriodicalIF":1.9,"publicationDate":"2026-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/btp.70251","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148942226","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Studies investigating the patterns and mechanisms of such elevational shifts have been limited in spatial scale owing to the difficulty of sampling data across montane gradients. Here, we integrated data from the world's largest participatory science project (eBird) with systematic surveys to examine patterns and mechanisms that may explain bird elevational range shifts in the Nilgiri Hills of the Western Ghats Biodiversity Hotspot. We calculate the extent of shifts in elevational ranges for birds present year-round in the Nilgiris between the hottest and coldest quarters and quantify the associations between these shifts and species traits using phylogenetic generalized least squares regressions. We found that 77% (54/70) of the species investigated showed seasonal shifts in their elevational ranges. Birds in the Nilgiris showed nearly equal proportions of downslope (37%) and upslope (33%) winter shifts. All species had significant range overlap between seasons but employed different shifting strategies. Species with narrow thermal regimes predominantly shifted downslope in winter (niche tracking), while those with the widest thermal regimes shifted upslope (niche switching), revealing that species adapt to climatic variability through contrasting thermal strategies. Our results suggest that climatic constraints, specifically thermal regime, could be a major driver of seasonal shifts in elevational ranges of birds in the Nilgiris. Understanding these elevational shift strategies is critical for conservation planning in tropical montane systems facing accelerating climate change.\u0000 </div>","PeriodicalId":8982,"journal":{"name":"Biotropica","volume":"58 5","pages":""},"PeriodicalIF":1.9,"publicationDate":"2026-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148849232","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study we tested whether Panacea prola, a butterfly species found throughout the western Amazon and adjacent Andean foothills, was migratory at a site in lowland southeastern Peru. We show, through direct observation of flight behavior, that P. prola migrated annually between 2021 and 2025 during the dry season at the study site. We further show that the flight path of migrating P. prola butterflies is nonrandom and roughly northeast, leading toward the central Amazon basin. The discovery of a previously undocumented migration in a widespread and conspicuous butterfly is an important contribution to our currently poor knowledge of insect migration in the Amazon, the world's largest and most biodiverse tropical forest.","PeriodicalId":8982,"journal":{"name":"Biotropica","volume":"58 5","pages":""},"PeriodicalIF":1.9,"publicationDate":"2026-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/btp.70253","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148848871","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Paradoxically, for many threatened species, this knowledge remains poorly explored. We investigated the environmental variables influencing pool use by tadpoles of Incilius spiculatus, a Mexican microendemic toad, to understand how undergoing habitat changes can affect it. We worked along reproductive sites in riverbanks where small-scale agriculture has recently increased. By measuring physical and chemical characteristics of used and unused pools, we identified the variables influencing their use. We also measured air and water temperatures across three years and water temperature changes along a canopy cover gradient. Tadpole pool use was associated with specific ranges of canopy cover, organic matter, pool depth, and water temperature. Over three years, air and water temperatures increased, and canopy cover decreased. Notably, tadpoles kept selecting available pools at a temperature range around 19°C and with canopy coverage of at least 60%, suggesting specific preferences. Measurements on water temperature in a canopy cover gradient showed that locally, temperature can increase up to 1°C with riparian vegetation reduction. We provide information of microhabitat needs for tadpoles of an endangered tropical toad whose populations are considered decreasing by fragmentation. Our results suggest tadpole vulnerability to water temperature rise exacerbated by deforestation as another threat. This is the first study focused on tadpole requirements and threats for this tropical species, a crucial knowledge to design restoration measures that incorporate habitat needs of both amphibian life stages and understand possible similar responses in other tropical amphibians.\u0000 </div>","PeriodicalId":8982,"journal":{"name":"Biotropica","volume":"58 5","pages":""},"PeriodicalIF":1.9,"publicationDate":"2026-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148848898","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While research has traditionally focused on small ingested seeds, tent-roosting bats also disperse large, undigested seeds, potentially benefiting large-seeded forest species in disturbed areas. However, the factors influencing this dispersal remain poorly understood. At La Selva Research Station, Costa Rica, we used a hierarchical statistical framework to assess how a forest disturbance gradient (low, intermediate, high) influences host plant abundance, bat tent abundance, and large-seed dispersal. Host plant abundance did not show a statistically significant response to disturbance. Bat tent abundance and total large-seed dispersal showed higher point estimates in the intermediate-disturbance zone, but the evidence for a clear effect of disturbance was weak. The total seed output in low- and high-disturbance zones was only 6% and 7%, respectively, of that in the intermediate zone, although this pattern was not statistically confirmed. Seed dispersal efficiency per tent, however, did not vary across the gradient. Taken together, our results point to a possible concentration of bat tent abundance and large-seed dispersal in intermediate-disturbance areas, but the statistical evidence was weak and further studies are required to substantiate these patterns. Even so, the observed patterns hint that tent-roosting bats could be previously overlooked agents that contribute to the natural regeneration of degraded tropical forests. By dispersing large seeds often characteristic of old-growth species, their conservation might potentially enhance the recovery of forest structure and composition.\u0000 </div>","PeriodicalId":8982,"journal":{"name":"Biotropica","volume":"58 5","pages":""},"PeriodicalIF":1.9,"publicationDate":"2026-08-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148848733","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
