ABSTRACTThe current study aimed to recognize the floral resources used by bees of the genus Xylocopa in transition physiognomies. We compiled the information available from biological collections and analyzed metrics of dystrophic interaction. We listed 2547 records of Xylocopa in flowers, across twelve identified bee species. The bees were collected from 109 plant species, belonging to 77 genera and 36 families. An interaction network was constructed based on 193 interactions. In which there was a significant correlation between the abundance of bees collected and the richness of plants visited. The most generalist bees were X. cearensis and X. frontalis, and the plants with the most records were Chamaecrista hispidula and C. ramosa. Significant seasonality was observed in the total number of individuals. On the other hand, there was a weak similarity among Xylocopa species according to plant species, despite the clear relationship of the bees according to physiognomies. The interaction network proved to be highly nested, indicating a functional partitioning that allows several species to occur in the same environment. The contribution made by the current work for its regional scope stands out, dealing with areas that have distinct characteristics.KEYWORDS: Solitary beespollinationplant-pollinatorinteraction networkecotone AcknowledgmentsThe authors gratefully acknowledge Márcia Maria Correa Rêgo for support in acquiring the historical data on the surveys conducted in Maranhão; CAPES for the scholarship granted to LACF; and the Federal University of Maranhão for the infrastructure and technical support.Disclosure statementNo potential conflict of interest was reported by the authors.Additional informationFundingThis work was financed by the Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - Brazil (CAPES) - Código de Financiamento 001 and Fundação de Amparo à Pesquisa e ao Desenvolvimento Científico e Tecnológico do Maranhão (FAPEMA).
摘要本研究旨在了解木蝇属蜜蜂在过渡地貌中所利用的花卉资源。我们从生物收集中收集信息并分析营养不良相互作用的指标。我们列出了2547条Xylocopa在花中的记录,涵盖了12种已确定的蜜蜂物种。蜜蜂来自植物109种,隶属于36科77属。基于193个交互构建了交互网络。其中收集到的蜜蜂的丰度和拜访到的植物的丰度之间存在显著的相关性。蜜蜂的通用化程度最高的是X. cearensis和X. frontalis,记录最多的植物是Chamaecrista hispidula和C. ramosa。在个体总数中观察到显著的季节性。另一方面,根据植物种类,木蝇种类之间的相似性较弱,尽管从外貌上看它们之间的关系很明显。相互作用网络被证明是高度嵌套的,表明一个功能分区允许几个物种在同一环境中发生。目前的工作对其区域范围所作的贡献是突出的,它涉及具有明显特点的地区。作者感谢Márcia Maria Correa Rêgo为获取maranh调查的历史数据提供支持;LACF奖学金的CAPES;马拉赫联邦大学提供基础设施和技术支持。披露声明作者未报告潜在的利益冲突。本研究由巴西高级经济与社会发展协调组织(CAPES) - Código de Financiamento 001和巴西高级经济与社会发展协调组织(Código de Financiamento 001)和巴西高级经济与社会发展协调组织(Científico e Tecnológico do maranh)资助。

A depauperate Chiropterofauna consisting of essentially three bat species (the year-round residents Histiotus magellanicus and Myotis chiloensis, and the apparently migratory Lasiurus varius), exists in the challenging cold and windy environment of the Magellanic/Fuegian region, which encompasses territories in Argentina and Chile, both continental and insular. Knowledge of that bat fauna benefitted from earlier explorers and naturalists visiting such southerly and isolated geographical confines, but still lacks a comprehensive scientific study, particularly in face of expected green-energy projects using aerogenerators known to cause bat fatalities elsewhere. Currently, there is a paucity of information on the fine-scale geographic distribution, local abundance, and migration patterns of those bats that needs to be remedied as soon as possible. Our review may aid orienting and focusing such a research program, which should hopefully be binational, on account of the artificial nature of the border between Argentina and Chile in Tierra del Fuego.

ABSTRACTKnowledge of Didelphidae taxonomy and diversity has increased steadily over the last decades, mainly due to increasing collection efforts and revisionary works. Yet, especially for mouse opossums, a proper appraisal of morphological variation is still incipient. Thylamys karimii occurs in the Brazilian biomes of Caatinga and Cerrado, and specimens with two different shades of dorsal coloration (brown and gray) were recently documented in sympatry in the Parque Nacional (PARNA) do Catimbau (Caatinga biome). We used qualitative and morphometric data from skulls and skins (n = 7 from PARNA Catimbau and n = 26 from other localities) to compare these two coat color morphotypes and characterize the morphological diversity and taxonomic status of the Caatinga populations. We used Student’s t-tests to compare sexes and morphotypes’ measurements. We found at least three well-defined coat color morphotypes distinguishable by dorsal and ventral coloration and not restricted to PARNA Catimbau. Variation of the other morphological traits suggests that these morphotypes are more likely a case of intraspecific variation in the Brazilian northeastern region. Morphometric differences, particularly between coat color morphotypes, might be better elucidated in larger samples. Additionally, these specimens represent an important extension of the species’ known distribution reaching the Atlantic Forest borders.KEYWORDS: Opossumsmorphotypescolorationpelage colorCaatinga AcknowledgmentsWe are thankful to Pedro Cordeiro-Estrela (UFPB, João Pessoa, Brazil), and the support staff of the Mammal Collections we visited for their support and infrastructure during the analysis of the vouchers.

摘要近几十年来,人们对didiphidae的分类和多样性的了解稳步增加,这主要是由于收集工作和修订工作的增加。然而,特别是对于鼠负鼠,对形态变异的适当评估仍处于初级阶段。卡里米Thylamys karimii出现在Caatinga和Cerrado的巴西生物群系中,最近在国家公园(PARNA) do Catimbau (Caatinga生物群系)中记录了两种不同背色深浅(棕色和灰色)的标本。我们利用来自PARNA Catimbau和其他地区的头盖骨和皮肤的定性和形态测量数据(n = 7和n = 26)比较了这两种毛色形态,并表征了Caatinga种群的形态多样性和分类地位。我们使用学生t检验来比较性别和形态的测量结果。我们发现至少有三种明确的被毛颜色形态,可以通过背侧和腹侧的颜色来区分,而且不仅限于PARNA Catimbau。其他形态特征的变异表明,这些形态型更可能是巴西东北部地区种内变异的一种情况。形态计量学上的差异,特别是毛色形态之间的差异,可能在更大的样本中得到更好的阐明。此外,这些标本代表了该物种已知分布到达大西洋森林边界的重要延伸。我们感谢Pedro Cordeiro-Estrela(巴西jo o Pessoa的fpb)和哺乳动物馆藏的支持人员,感谢他们在分析代用券过程中提供的支持和基础设施。Ana Paula Carmignotto (UFSCar, Sorocaba, Brazil)和Marcos brand o (USP, s o Paulo, Brazil)在本文还是本科论文时就提出了重要的意见和建议,两位匿名审稿人的意见帮助我们改进了最终的文本。我们还感谢国家自然历史博物馆(巴黎)提供的全像照相。披露声明作者未报告潜在的利益冲突。本研究得到了CNPq、CAPES和FACEPE对DA和UFPE哺乳动物馆藏的资助。在这项工作的发展过程中,MC得到了upe - cnpq (inicia o scientificica)奖学金和SBMz的资助,目前由FACEPE MSc支持。奖学金(ibpg - 0154 - 2.04/22)。

ABSTRACTDiapause is a process of decreased metabolic activity in insects. In latitudes with a well-defined cold season, diapause or hibernation is a strategy to survive in periods of resource scarcity. In Pentatomidae, this phenomenon is studied mainly in non-natural environments and with species of economic importance. This work aimed to determine which variables influence the abundance of Brachystethus geniculatus on its hibernation site, Bromelia antiacantha. Samplings were carried out monthly, from July to September of 2019, in a remnant of Atlantic Forest in southern Brazil. The height, diameter, cup height, leaf width, and abundance of bromeliads per plant cluster were evaluated for their correlation with the abundance of B. geniculatus in bromeliads. We collected 24 individuals for analysis of fat bodies, in order to check diapause. We found 70 individuals of B. geniculatus distributed in 33 of the 61 bromeliads examined. The number of B. geniculatus per bromeliad was positively correlated with the cup height, that influences the opening of the leaves and consequently decreases the exposure to environmental weathering, and the number of bromeliads per group, possibly because more leaves and spines around the cup may help avoid predation. Parasitism on B. geniculatus by tachinid flies was recorded in the field.KEYWORDS: Atlantic Forestcorrelationstink bugmicro-habitatparasitism AcknowledgmentsWe thank all the friends and colleagues who help in the field search and the manuscript revision, especially Dr. Filipe Michels Bianchi (UFRGS), Dr. Luiza Rodrigues Redaelli (UFRGS) and Dr. Patrick Colombo (SEMA), for their valuable contributions to the final version of the manuscript.Disclosure statementNo potential conflict of interest was reported by the author(s).Additional informationFundingThis study was partially financed by CNPq fellowship to the first author [grant 122920/2016-3].

ABSTRACTFood habits are traces of a species’ natural history that help us to understand how the organisms interact with the environment. Hylaeamys seuanezi is a forest-specialist rodent also recorded in diverse shaded cocoa agroforestry systems. Here we describe and classify its diet, comparing the results acquired from stomach and fecal contents, collected in forest and cocoa agroforest sites. We analyzed 203 samples from 126 individuals: 51 captured in agroforest and 75 in forest. We measured the relative contribution of vegetable and animal matter and the relative frequency of 17 food items. Our results indicate that H. seuanezi consumes a greater proportion of vegetable than animal matter, but should be considered omnivore, given the frequent consumption of arthropods. The richness and composition of items was similar between stomach and fecal samples. The richness of items also did not vary between the environments, but the composition of the items did. Intact seeds were more frequent in samples from forests and unidentified arthropods and Hymenoptera in samples from agroforest. Despite variation among consumed items, the diverse shaded cocoa agroforestry systems provide a diversity of resources, which likely favor the maintenance of H. seuanezi in these plantations and in the study region.KEYWORDS: Atlantic Forestdietsmall mammalfeeding ecology AcknowledgmentsWe thank the Laboratório de Ecologia Aplicada à Conservação and Laboratório de Zoologia de Vertebrados for logistical support, and Caipora’s and Rhip’s fraternities, specitally to Adna Alves, Elson Rios, Gean Zanetti and Rebeca Sampaio, for field and data collection assistance.

ABSTRACTResearch on trophic niche dimensions is essential to understanding the role of species in ecosystems. In the case of amphibian conservation, it is particularly important to study juveniles, given the vulnerability of this life stage. Here, the diets consumed by juvenile Rhinella arenarum and Odontophrynus sp. were evaluated, with special attention paid to the incidence of ants. Diet composition was quantified by analyzing the amphibians’ stomach contents. The representation of different taxonomic prey groups was determined, and the relationships between the amphibians’ morphological traits and the characteristics of their prey were explored. Diet composition and diversity differed between juveniles of the two species. Juvenile R. arenarum occupied an intermediate position along the specialist-generalist spectrum. Their most commonly consumed prey were ants (mainly Solenopsis and Linepithema) followed by mites. Juvenile Odontophrynus sp. had a more generalist diet. Their most commonly consumed prey were Isopoda followed by Coleoptera and miscellaneous larvae. Snout-vent length (SVL) was greater for juvenile Odontophrynus sp. than for juvenile R. arenarum, but the latter consumed more prey. The results suggest that juveniles of R. arenarum tend to specialize more on ants than do juveniles of Odontophrynus sp.KEYWORDS: Anurajuvenile amphibiansFormicidaetrophic ecologyRhinellaOdontophrynus AcknowledgmentsWe thank Francisco Sola and Martín Bolazzi for identifying some ant genera and species.

ABSTRACTDelimiting biogeographic regions based on occurrence data is an interesting approach to investigating processes behind biodiversity distribution patterns. Comparing spatial scales and identifying predictor variables of biogeographic regions have wide application for biodiversity conservation. In this study we used a comprehensive database containing more than thirty years of horse fly records to estimate species richness, endemism, and species composition, and regionalize the Amazon biogeographically. We compared five spatial scales defined by grid size (1–5º), and test five hypotheses (elevation, climate, vegetation cover, and two regionalizations from the literature) to identify predictors of the biogeographic regions. Endemism, species richness and composition were predicted by different sets of predictor variables, although the models were highly dependent on spatial scale. We identified three well-defined biogeographic regions, which have been formed by a combination of geographic distance, climate and historical factors converging with some theories proposed for mammals. Our models indicated dispersal as a key factor for regionalization, as it can be constrained by a combination of climate and historical processes changing habitats over time, although this finding was highly dependent on spatial scale. We showed that horse flies are interesting models for biogeography although they have been historically neglected.KEYWORDS: EndemismNeotropicsspatial scalespecies compositiontabanid AcknowledgmentsWe thank all the curators of the entomological collections visited, the Instituto Nacional de Pesquisas da Amazônia for the logistical support in the expeditions, and Professor Francisco Xavier (Chico) for technical support.Disclosure statementNo potential conflict of interest was reported by the author(s).Supplementary materialSupplemental data for this article can be accessed online at https://doi.org/10.1080/01650521.2023.2254505Additional informationFundingALH thanks the Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq) for financial support (Programa Ciências Sem Fronteiras, grant number [246878/2012-6]), ‘Ação transversal: Redes Regionais de Pesquisas em Biodiversidade e Tecnologia’, grant number 79/2013 grant number [407627/2013-8], project ‘Biodiversidade de Insetos na Amazônia-Rede BIA’ and Fundação de Amparo à Pesquisa do Estado do Amazonas, Edital Universal grant number [0002/2018], Project ‘Tabanidae da Amazônia: Taxonomia e Diversidade’.

摘要基于发生数据划分生物地理区域是研究生物多样性分布模式背后的过程的一种有趣的方法。生物地理区域的空间尺度比较和预测变量识别在生物多样性保护中具有广泛的应用价值。在这项研究中,我们使用了一个包含超过30年马蝇记录的综合数据库来估计物种丰富度、特有性和物种组成,并对亚马逊地区进行了生物地理区划。我们比较了由网格大小(1-5º)定义的5个空间尺度,并检验了5个假设(海拔、气候、植被覆盖和文献中的两种区划),以确定生物地理区域的预测因子。虽然模型高度依赖于空间尺度,但可以用不同的预测变量集来预测物种的地方性、丰富度和组成。我们确定了三个明确的生物地理区域,它们是由地理距离、气候和历史因素共同作用形成的,并与一些关于哺乳动物的理论相结合。我们的模型表明,尽管这一发现高度依赖于空间尺度,但分散是区域化的关键因素,因为它可能受到气候和历史过程随时间变化的限制。我们发现马蝇是生物地理学的有趣模型,尽管它们在历史上一直被忽视。关键词:EndemismNeotropicsspatial scalespecies compositiontabanid AcknowledgmentsWe感谢所有昆虫的集合的策展人,西班牙de尽管亚马逊探险的后勤支持,和旧金山泽维尔教授(Chico)技术支持。披露声明作者未报告潜在的利益冲突。补充材料本文的补充数据可在线访问https://doi.org/10.1080/01650521.2023.2254505Additional informationFundingALH感谢Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)的财政支持(Programa Ciências Sem Fronteiras,拨款号[246878/2012-6]),' aapart o transversal:“区域生物多样性研究与技术研究”,资助号79/2013,资助号[407627/2013-8],“生物多样性研究与技术研究”项目,“巴西生物多样性研究与技术研究”项目,“巴西亚马逊州生物多样性研究与技术研究基金”项目,“巴西Tabanidae数据Amazônia:生物多样性分类研究”项目,数字通用资助号[0002/2018]。TKK和DDDC感谢Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq)授予的奖学金(资助号分别为[310214/2021-1]和[151354/2022-7])。
