However, intermediate-intensity land use, such as agroforestry, can be a refuge for biodiversity and can maintain ecosystem functions and services in working landscapes. We quantified how the alpha and beta diversity of ants (Hymenoptera: Formicidae) vary with human land use in the Kodagu region of the Western Ghats, India, across four land use types (forests, forest fragments, and two types of coffee plantations with either native or non-native shade trees). We studied ants, as they perform a wide range of ecological functions such as predation, herbivory, seed dispersal, and decomposition, etc., in such landscapes. We also assessed the functional diversity of ants and estimated the interactions between their traits and the environment. We found that the plantations, on average, had 26% lower species richness than forests and forest fragments, and functional richness was 31% lower in non-native plantations. However, plantations showed higher beta diversity than forests at both taxonomic and functional levels. Interestingly, turnover was higher in non-native than native plantations by 32% and 24% at taxonomic and functional levels, respectively. Plantations also had weak and few ants' trait-and-environment interactions, suggesting that environmental filters may not be influential in structuring ant communities under human land use, compared to forests. Overall, while ant communities under human land use differ from those in forests, they can be heterogeneous and able to perform similar functions. Our findings highlight the importance of agroforestry as working landscapes which can maintain biodiversity and ecosystem functions.\u0000 </div>","PeriodicalId":8982,"journal":{"name":"Biotropica","volume":"57 3","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-04-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143840910","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}

We analyzed 4161 individuals representing 212 species from a larger dataset of 10,337 individuals and 749 morpho-species, using the latter for cross-validation, and related our findings to ambient temperature and vegetation cover. Our multivariate analysis at 22 sites from 1020 to 2700 m above sea level identified five species assemblage clusters, revealing a near-linear decrease in species diversity with cooler temperatures. Community-weighted means (CWMs) of forewing length, indicating body size, increased nearly linearly with dropping temperatures, contrasting with results found for Geometridae moths at the same sites. Forewing aspect ratio (AR) demonstrated a U-shaped relationship with temperature, while wing loading (WL) followed a hump-shaped trajectory. Around 2000 m, Pyraloidea assemblages exhibited the lowest AR and highest WL, indicating morphological adaptations to dense forests, in contrast to both the more open forests near the treeline and the tall rainforest found at lower elevations. Subfamily-level analyses revealed variable patterns: Acentropinae, with strictly aquatic larvae, showed larger sizes at cooler elevations but less wing shape variation, likely reflecting limited forest dependence on maneuverability. Musotiminae, with a larval diet of diverse ferns, exhibited wing morphologies more related to canopy openness than temperature, indicating adaptations to navigating different fern habitats along the gradient. Our observations reveal complex insect–environment interactions that challenge the applicability of just one common theoretical framework for explaining temperature–size relationships among different moth clades.","PeriodicalId":8982,"journal":{"name":"Biotropica","volume":"57 3","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/btp.70033","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143822146","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}

Nearly 80% of described species are separated by geographical barriers, including several mountain chains. River width exhibited a negative correlation with molecular similarity in adjacent taxa for both molecular markers. Several presently described taxa were not supported based solely on these molecular phylogenetic markers, including Saimiri, Mico, Cebus, Sapajus, and Cherecebus. These taxonomic issues are far more common where river barriers do not exist. In conclusion, we found a significant correlation between river width and molecular divergence in adjacent taxa, indicating that wider rivers were associated with greater molecular divergence for two commonly used mitochondrial genes. Species boundaries were predominantly found at river interfaces, and in the absence of discernable geological barriers, adjoining species were more likely to exhibit molecular similarity. Our findings suggest that river and mountain barriers are significantly associated with gene flow for neotropical primate taxa.

The osmometer method enables the rapid determination of the leaf water potential at turgor loss (πtlp), a key parameter of drought tolerance, from the osmotic potential at full turgor (πsat). However, despite its wide applications, there have been few validations in ever-wet tropical rainforests. Here, we assessed the efficacy of the osmometer method in dipterocarps, a dominant tree group in SE Asia in ever-wet Malaysia, and examined the linkage between πtlp and distribution along a rainfall gradient. The πtlp determined using the conventional method was strongly and linearly correlated with the πsat determined using an osmometer. The coefficients of our model were statistically identical to those previously represented, but with a slightly larger intercept (0.21 MPa). Species with more negative πtlp were distributed in drier habitats, with a relatively larger variation in πtlp for species confined to ever-wet climates than for those occurring in ever-wet and seasonally dry climates. Some leaf traits, individual leaf area and dry matter content, were associated with πtlp, but these traits alone could not predict species distribution. We demonstrated the robustness of the osmometer method in ever-wet tropical rainforest species and that πtlp is associated with current distribution along large-scale moisture availabilities.\u0000 </div>","PeriodicalId":8982,"journal":{"name":"Biotropica","volume":"57 3","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-04-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143818337","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 the present study, we provide information on variation in lizard diversity across different vegetation types in a protected area located in the southern portion of the Cerrado and evaluated the effect of vegetation density on lizard taxonomic, functional, and phylogenetic diversity. We predicted that the three aspects of lizard diversity would be negatively affected by vegetation density and that Beta diversity would vary significantly across the vegetation gradient. We confirmed nearly all of our predictions, except for functional diversity, which, contrary to our expectations, was positively influenced by vegetation density. We also found that Beta diversity indices based on both species composition/abundance and phylogenetic features of communities experience a significant turnover across the vegetation density gradient. This study greatly strengthens previous studies that suggest a negative impact of vegetation density (and, consequently, woody encroachment) on lizard diversity. Therefore, managers of protected areas in the Cerrado should consider the use of strategies to avoid woody encroachment, like fire management with prescribed fires.\u0000 </div>","PeriodicalId":8982,"journal":{"name":"Biotropica","volume":"57 3","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143793617","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}

We examined monthly patterns in the percentage of species and trees in leaf flush, flower, and fruit and characterized phenological seasonality using circular statistics. We hypothesized that phenological patterns would show significant seasonality, with phenological activity being triggered by increasing solar irradiance and daylength. Flowering periodicity was classified using Fourier analysis, and we examined the relationships between phenological activity and temperature, rainfall, solar radiation, and daylength using GAMLSS. Leaf flush and flowering were moderately seasonal, peaking in the warm dry season. Fruiting patterns and their seasonality differed among dispersal modes. Most species (78.13%) and trees (51.17%) flowered annually. In accordance with our hypothesis, daylength and solar radiation served as proximate cues for phenological activity through nonlinear effects. This indicated the existence of narrow ranges of optimal climatic conditions for phenology. Rainfall was not an important proximate cue as water availability was not a constraint for tree phenology in the site.

Here, we assessed past human activities and vegetation change from a well-studied research station in the Peruvian Amazon using charcoal and phytoliths recovered from soil cores. The moderate seasonality has contributed to its high diversity, while its remoteness has generally led to assumptions of minimal past land modification by humans. We asked: (i) Is there evidence of past human influence, including cultivation, forest opening, or plant enrichment/depletion, in the forests around Cocha Cashu Biological Station? and (ii) was there a consistent increase in palm phytolith abundances through time as has been documented in the aseasonal forests of northwestern Amazonia? Only 38 (14%) of the 279 samples analyzed contained charcoal, highlighting the rarity of past fire at Cocha Cashu. The two charcoal fragments large enough for 14C dating had ages of 570–670 and 1350–1520 calibrated years before present. No cultivar phytoliths were found. Spheroid echinate phytoliths, produced by the palm genera Attalea, and Oenocarpus, and Euterpe, were more abundant in past samples than in modern samples. There was no increase in palm phytolith abundances from the bottom to top of the core, contrasting with recent findings from northwestern Amazonia.

Focusing only on original scientific articles, we described the trends in the topics and taxa studied, the publication languages, the authorship, and study sites. We used two datasets: one from the Web of Science (WoS; 2223 articles) and another from three Madagascar-focused journals (MFJ; 329 articles). The observation of lemurs in the wild is the oldest form of Lemurology, starting under the French colonization, and remains the main data source for articles in both datasets. Microcebus and Eulemur are the most studied genera in WoS and Propithecus and Eulemur in MFJ. At this time, no articles are written in Malagasy, but English and French are the main languages used in Lemurology. Although Malagasy scientists are still underrepresented at the international level, there is a recent shift toward an increased number of Malagasy scientists as first and last authors. We found no gender bias in WoS, but MFJ exhibited noticeable male author dominance. Most Lemurology has been conducted at the Duke Lemur Center (USA), followed by Kirindy and Ranomafana forests in Madagascar. Lemurology thus shows different portraits at international and local levels, suggesting that unequal access to resources and opportunities may hinder the effective investigation and conservation of lemurs.","PeriodicalId":8982,"journal":{"name":"Biotropica","volume":"57 2","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1111/btp.70026","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143689416","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}

Understanding the differences in plant–pollinator interactions and pollinator importance across spatial scales is vital to determine the responses of these interactions to global changes.

Here, we compared the differences in species composition, plant–pollinator network structure, and pollinator importance in communities between a continental island (Wanshan Island) and an oceanic island (Yongxing Island) in China. The results reveal highly dissimilar species composition between continental and oceanic islands that caused highly different plant–pollinator network structures. In particular, the oceanic island networks had higher network connectance, nestedness, and specialization than the continental island networks. For plants cooccurring on both islands, pollinator species richness and flower visitation rate were higher on the continental island than on the oceanic island. Plant niche overlap was higher on the oceanic island than on the continental island, while pollinator niche overlap was higher on the continental island than on the oceanic island in both the entire network and cooccurring plant species subnetwork. Hymenoptera was the most important pollinator group in the continental island community, while Apidae was the most important in the oceanic island community. The results imply that oceanic island communities may be less vulnerable to disturbance, such as habitat alteration or destruction, than continental island communities and provide implication insights into biodiversity conservation for pollinators on islands.\u0000 </div>","PeriodicalId":8982,"journal":{"name":"Biotropica","volume":"57 2","pages":""},"PeriodicalIF":1.8,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143689415","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}
