Although most research on endozoochory has focused on birds and mammals, some lizards are also known to consume fruits and play a significant role in seed dispersal. However, lizards remain overlooked as frugivores and seed dispersers. To clarify the role of lizards as seed dispersers in forest ecosystems, we conducted behavioral observations and fecal analyses on three diurnal lizard species: Furcifer oustaleti, Oplurus cuvieri, and Zonosaurus laticaudatus in a tropical dry forest in Ankarafantsika National Park, northwestern Madagascar during the wet seasons from 2022 to 2024 (2 years). We also conducted germination trials on seeds defecated by F. oustaleti and O. cuvieri. We captured 89, 254, and 38 individuals of the three lizard species, and 24.7 %, 20.1 %, and 15.8 % of the individuals had seeds in their feces, respectively. Behavioral observations and fecal analyses revealed that F. oustaleti, O. cuvieri, and Z. laticaudatus consumed fruits from 8, 18, and 8 plant species, respectively. For individuals with seeds in their feces, the mean number of defecated seeds per individual was 27.2 (range: 1–300), and we confirmed that some of these species had substantial germination rates (> 50%). Moreover, lizards tended to consume different plant species compared to the Common Brown Lemur (Eulemur fulvus), a principal seed disperser in this forest. These lizards may therefore play important roles as seed dispersers, and their contribution to forest regeneration in Madagascar should be considered.\u0000 </div>","PeriodicalId":8982,"journal":{"name":"Biotropica","volume":"57 4","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144171530","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}

Here, we provide the first comparison of floral scent chemistry in shade houses and natural populations of orchids in central Africa. We investigate floral scent variations between two shade houses and one natural site in a sphingophilous epiphytic orchid, Cyrtorchis letouzeyi, in Cameroon. Samples were collected in and ex situ through the dynamic headspace method and analyzed using gas chromatography coupled with mass spectrometry. Both composition and relative emission rate were analyzed with temperature and humidity levels recorded at the time of sampling. The floral scent was dominated by both aromatics and isoprenoids and derivatives, including methyl benzoate, linalool, and pyranoid and furanoid forms of linalool oxide. Variations in temperature and humidity had no significant impact on the floral scent composition but on relative emission rates. Samples under shade house cultivation produced the same compounds as those in the natural environment. Quantitatively, differences were recorded in the proportions of volatile organic compounds (VOCs) produced, but the main compound remained unchanged in both environments. Dissimilarities were driven by the production of linalool and its derivatives. Based on these findings, we suggest that shade houses are a suitable tool to characterize the qualitative floral scent diversity of tropical epiphytic orchids and can therefore serve to complement in situ sampling.","PeriodicalId":8982,"journal":{"name":"Biotropica","volume":"57 3","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/btp.70036","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144126076","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}

A synthesis of the current knowledge about this unique taxonomic group is, therefore, timely to establish a foundation for future studies that can be used in evidence-based actions in both in situ and ex situ conservation settings. This review explores the extensive body of published research about lemurs, consolidating findings from various studies. Covering a range of topics, the review synthesizes about 120 years of scientific articles, starting in 1900, to summarize current advances in scientific studies about lemur, that is, “Lemurology”, beyond reports of their discoveries and descriptions. It also addresses the conservation challenges these animals face, emphasizing the urgent need for effective protective measures. By synthesizing and analyzing a wealth of scientific literature, this review can serve as an important resource for researchers, conservationists, and educators interested in lemur biology and conservation.","PeriodicalId":8982,"journal":{"name":"Biotropica","volume":"57 3","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/btp.70047","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144108748","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}

Yet, stingless bee impact on pollination depends on how many and which pollen types they use, and the relative importance of different factors affecting bee choice for pollen is uncertain. Further, empirical syntheses on bee–plant interactions have largely neglected the Amazon, where stingless bees are major pollinators. Here, we tested phenotypic, environmental, and anthropogenic effects on stingless bee pollen niche across the Brazilian Amazon. We assembled literature data on 242 pollen types collected by 36 species of stingless bees, which were sampled across 1450 km during 1975 to 2012. In this study, the pollen niche is defined by two dimensions: the number and set of pollen taxa collected by stingless bees, representing diversity and composition of the gathered pollen. We modeled the response of the pollen diversity and composition to (1) bee species body mass, (2) tree diversity, (3) tree composition, (4) rainfall, (5) urbanization, and (6) sampling year while accounting for the pollen sampling method, pollen taxonomic uncertainty, and bee phylogenetic relatedness. Pollen diversity decreased with body mass and over time but was higher in urban compared to wild colonies. Pollen composition changed with body mass, tree composition, and year. These relationships were independent of colony sampling method and bee phylogeny and were robust even under uncertainty in pollen taxonomic identification. We show that larger stingless bees are more selective foragers, but much of the variation in their pollen niche across the Brazilian Amazon reflects urbanization, plant resources, and geographical patterns in climate. The long-term change of stingless bee pollen niche can have serious consequences for pollination in the region.","PeriodicalId":8982,"journal":{"name":"Biotropica","volume":"57 3","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/btp.70049","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144100492","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}

Although sapling growth is essential to this process, information on how it changes along succession is scarce. Here, we examine relative growth rates (RGR) of woody species saplings along a broad successional gradient in a tropical dry forest based on height and basal area data gathered over 15 years of vegetation monitoring in permanent plots differing in successional age (1–73 years) plus a mature forest plot. We used mixed-effects models to examine the link between individual size, fallow age, and plant traits, and from this link model their relationship with sapling RGR. Despite sizable RGR variability, growth was generally slow over the successional gradient, except in the first 10 years of succession, when growth rates were highest for most groups. Species' successional guild and their identity as members of the Leguminosae family were the main factors responsible for growth in basal area, while for growth in height, the main factors involved were successional guild and growth form. A generalized decrease in sapling growth rates in the understory suggests that this process is increasingly limited by light rather than by water towards later successional stages. Enhanced knowledge of the dynamics of the regenerating community in tropical dry forests is fundamental for gaining a comprehensive view of their recovery.","PeriodicalId":8982,"journal":{"name":"Biotropica","volume":"57 3","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/btp.70046","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143949952","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}
