Abstract The length-weight relationship parameter is important for obtaining fish weight and biomass data with relevant implications about species role on ecosystem functioning. Here we report the length-weight relationship (LWR) for 24 fish species from three streams located in the Atlantic Forest in the Rio de Janeiro State, Brazil. Fish were collected with electrofishing and standard length (cm) and wet weight (g) were measured to obtain the a and b parameters of the Log (W) = Log (a) + b Log (SL) equation. Length-weight relationships for seven out of 24 species (Hypostomus punctatus, Deuterodon taeniatus, Deuterodon hastatus, Deutorodon janeiroensis, Characidium vidali, Characidium interruptum and Rineloricaria zawadiskii) are reported for the first time. The length-weight relationships reported here contribute to the database that can support fish diversity conservation, fisheries management plans and studies on fish biology.

Abstract Beaucarnea inermis is an endemic species from Northeast Mexico, in the states of San Luis Potosí and Tamaulipas. It is appreciated as an ornamental plant, so its populations are subject to the poaching of individuals for illegal trade. Previous studies determined that their populations have been affected due to the disturbance since the incidence of anthropogenic activities affects the viability of the species. Here we determine the current conservation status of B. inermis and identify their main risk factor by performing an extinction risk assessment based on the Annex II “Method for Evaluation of Risk of Extinction of Plants in Mexico”. We studied 10 populations of B. inermis from protected and non-protected areas in San Luis Potosí and Tamaulipas. We considered the MER criteria: A) geographical distribution characteristics, B) habitat characteristics, C) intrinsic biological vulnerability, and D) impact of human activity. Using field and analyzed data, the MER assessment gives 1.91 points that confirm B. inermis is correctly classified as an Endangered species. The natural protected areas where the species occurs represent cores for its protection; however, the surface of these areas may not be sufficient without biological corridors that connect them.

Abstract Croton is the largest genus of Crotonoideae Burmeist. (ca. 1200 species), with approximately 300 species distributed in all the phytogeographic domains in Brazil. The Chapada of Araripe Environmental Protection Area (CA-EPA) is one of the largest protected areas in northeastern Brazil and comprises many different types of vegetation. Considering the expressive representation of Croton in that northeastern region and its morphological complexity, we carried out a taxonomic study of the species occurring in the CA-EPA. The analysis of collections deposited in regional herbaria, together with field observations, revealed 18 Croton species, five of which had never been cited as occurring in the study area; seven of those taxa are endemic to the Brazilian semiarid region. Croton species were recorded in all of the vegetation types in the CA-EPA, especially in the “carrasco” and “caatinga” vegetation. The plants habits, the shapes of their stipules, extrafloral nectaries, indumenta, and staminate and pistillate sepals were important characteristics for their differentiation.

Abstract The first list of Aetalionidae and Membracidae species for western Acre is presented, including the Alto do Juruá regions of Serra do Divisor National Park and the Campus Floresta of the Federal University of Acre. In total, 94 species of treehoppers were collected, of which Centrotinae (Membracidae) is recorded for the first time for Brazil (Abelus maculatus Schimidt), another 16 species are new Brazilian records, and 69 species (Aetalionidae and Membracidae) are new records for Acre. Data on type locality, geographic distribution and images of all species are presented. The males of Lophyraspis fenestrata Sakakibara & Creão-Duarte and Erechtia sanguinolenta (Fairmaire) are known for the first time. The species diversity was compared to four other treehopper surveys in the Amazon region, with similarity indices of about 43.6% for Colombian Amazon (at least 650 km away), 27.6% for Panguana Biological Research Station, Peru (250 km), 20.2% for Adolpho Ducke Forest Reserve, Brazil (1,600 km) and 8.5% for Villa Carmen Biological Station/Los Amigos Biological Station, Peru (600/700 km). The estimated richness of Serra do Divisor National Park was just over 70%, suggesting that local diversity could be significantly higher than that presented in this study.
摘要/ Abstract摘要:本文首次列出了阿克雷西部地区的Aetalionidae和Membracidae物种，包括Serra do Divisor国家公园的Alto do juru地区和阿克雷联邦大学的Campus Floresta校区。共采集到树跳昆虫94种，其中巴西为首次记录树跳亚科(Abelus maculatus Schimidt)，巴西为新记录树跳亚科(Abelus maculatus Schimidt) 16种，巴西为新记录树跳亚科(Aetalionidae)和树跳亚科(Membracidae) 69种。介绍了所有物种的类型、地理分布和影像资料。Sakakibara Lophyraspis fenestrata &;cre o- duarte和Erechtia sanguinolenta (Fairmaire)首次为人所知。与其他4个亚马逊地区的跳树虫物种多样性调查结果相比，哥伦比亚亚马逊(至少650公里)的相似性指数约为43.6%，秘鲁Panguana生物研究站(250公里)的相似性指数为27.6%，巴西Adolpho Ducke森林保护区(1600公里)的相似性指数为20.2%，秘鲁Villa Carmen生物站/Los Amigos生物站(600/700公里)的相似性指数为8.5%。Serra do Divisor国家公园的估计丰富度刚刚超过70%，表明当地的多样性可能明显高于本研究的结果。

Abstract Artificial impoundments are frequently built to mitigate the water scarcity in the drylands such as the Caatinga region in Brazil. The São Francisco Interbasin Water Transfer (SF-IWT) megaproject implemented many artificial reservoirs for that purpose. A checklist of fish species from the SF-IWT reservoirs is provided based on samples from eight years of monitoring. The collections were conducted semiannually at 28 reservoirs divided into three groups: the East Axis, North Axis, and Agreste Branch. The SF-IWT reservoirs presented a total of 47 species, 46 were recorded in the North Axis, 27 in the East Axis, and only seven in the Agreste Branch. Characids and cichlids represented most of the species. The three analyzed groups of reservoirs presented distinct communities and the reservoirs’ age, richness and abundance were relevant variables responsible for fish composition. The SF-IWT reservoirs present a diverse and heterogeneous ichthyofauna, typical of lentic environments. The main colonizers of the SF-IWT reservoirs were fish from the São Francisco donor basin, invasive species anthropically released in those sites, and eventual species from the surrounding receiving basins. As the accumulation curves suggested, a continuous effort could reveal additional species, patterns in long-term colonization, and contribute to data on the reservoirs’ future stabilization phase. Since invasive species were present in most reservoirs, along with donor-basin native species with potential to disperse to the receiving basins, a continuous and detailed monitoring is key for management planning and possible impacts assessment.

Abstract Iguaçu National Park is the second largest (1852.62 km²) protected area in the Atlantic Forest domain and harbors the largest area of semideciduous seasonal forest in Brazil. In this study, we present 795 subspecies and 787 species of butterflies that occur in this protected area and its surrounding areas, collected over 15 years and ten months using different non-standardized sampling methods. We also searched for additional records in the literature, entomological collections, and citizen science platforms on the internet. Among the sampled taxa, six are recorded for the first time in Brazil: Emesis orichalceus Stichel, 1916, Theope p. pakitzaHall & Harvey, 1998 (Riodinidae), Elbella v. viriditas (Skinner, 1920), Apaustus gracilis ssp. n. (Hesperiidae), Deltaya sp. n. (Nymphalidae), and Symbiopsis sp. n. (Lycaenidae). Another six are listed as endangered in lists of butterflies of conservation concern. The records for some species significantly increase previously documented distributions.

Abstract Understanding the diversity of insect galls is pivotal to the establishment of conservation planning in different Brazilian ecosystems. Here, we (1) characterize the insect galls found on plant host species, (2) identify the gall-inducing insects to the lowest possible taxonomic level, and (3) record the presence of gall-associated fauna. Our study was carried out monthly from August, 2017 to July, 2018 along nine trails in Serra da Bandeira, which is located in an area of Cerrado stricto sensu over a year. We found 48 distinct gall morphotypes, belonging to 12 botanical families. The most morphotypes commonly found were globoid (27.1%), lenticular (27.1%) and cylindrical (25%). The plant organs most affected by galling insects were the leaves (73%), followed by the stem (19%), flower (4%), inflorescence (2%) and fruits (2%). The host botanical families holding the highest number of galls were Fabaceae (26), Malpighiaceae (5) and Anacardiaceae, Combretaceae and Euphorbiaceae (3). We observed that the genus Copaifera Lindl. (Fabaceae) had the greatest diversity of gall morphotypes, harboring 19 morphotypes distributed in three species that occur sympatrically - Copaifera sabulicola J. Costa (Fabaceae), Copaifera depilis Dwyer (Fabaceae) and Copaifera luetzelburgii Harms (Fabaceae). For the first time in Brazil, we recorded the occurrence of galls on flowers of Manihot caerulescens (Euphorbiaceae), on inflorescences of Mimosa acutistipula (Fabaceae) and flower buds of Anacardium humile (Anacardiaceae), which were induced by Cecidomyiidae. Inducers of the order Diptera (Family Cecidomyiidae) were the most abundant, found in 14 morphotypes of galls. Regarding the associated fauna, we found insects primarily belonging the order Hymenoptera, and identified them as parasitoids. The information provided can be used highly by decision makers for conservation programs, as well as in other strategies for the conservation of biological diversity in the Brazilian Cerrado.
了解昆虫瘿的多样性对建立巴西不同生态系统的保护规划至关重要。在这里，我们(1)对植物寄主物种上发现的虫瘿进行了表征，(2)对诱导虫瘿的昆虫进行了尽可能低的分类鉴定，(3)记录了虫瘿相关动物群的存在。我们的研究从2017年8月到2018年7月每月进行一次，沿着Serra da Bandeira的九条小径进行，该小径位于塞拉多严格意义上的地区，为期一年。我们发现48种不同的胆形态，属于12个植物科。最常见的形态是球形(27.1%)、透镜状(27.1%)和圆柱形(25%)。受昆虫侵害最严重的植物器官是叶片(73%)，其次是茎(19%)、花(4%)、花序(2%)和果实(2%)。寄主植物科以蚕豆科(26个)、麻瓜科(5个)、桃心科、combretacae科和大戟科(3个)居多。(Fabaceae)的瘿形态型多样性最大，共有19种形态型，分布于3种共缘发生的种:Copaifera sabulicola J. Costa (Fabaceae)、Copaifera depilis Dwyer (Fabaceae)和Copaifera luetzelburgii Harms (Fabaceae)。在巴西首次记录了由cecidomiidae诱导的manhot caerulescens (Euphorbiaceae)花、Mimosa acutitola (Fabaceae)花序和Anacardium humile (Anacardium humile)花蕾上出现瘿虫的情况。双翅目(瘿蚊科)诱导剂最多，在14种形态的瘿虫中均有发现。结合区系发现昆虫主要属膜翅目，属寄生蜂。所提供的信息可以为保护计划的决策者以及巴西塞拉多生物多样性保护的其他策略提供高度参考。

Abstract Somatic characters are shared by many Chelodesmidae groups, and generic placement and species identifications traditionally have been based on gonopodal morphology. Female genitalic characters have been largely neglected and are rarely photographed or illustrated. This is rather unfortunate as the morphology of female genitalia presents important characters and may be decisive for developing a more robust family classification. We describe the heretofore unknown female of Sandalodesmus araujoi (Schubart, 1946), previously known only from the male holotype collected in São Paulo, Brazil in December 1943; discuss the utility of female genitalic characters for species delineation in Sandalodesmus; and report the first case of a mass occurrence in the Chelodesmidae. While an attempt at a formal diagnosis of Sandalodesmus females based on genitalic characters is premature, the vulvar morphology of the three taxa examined in this study suggests that female genitalia are species-specific. Some characters (i.e., asymmetric valves, presence of digitiform projections and reduction of setae on the internal basal portion of the valves) are constant between the species, suggesting utility for generic-level delineation. Mass occurrences of millipedes are typically unpredictable and likely related to variations in environmental conditions and/or anthropogenic modifications of natural habitats. Although the mass occurrence of S. araujoi reported herein was only observed once, the event coincides with the mating period of millipedes during the rainy season in Brazil. On the other hand, the region where the species was found has been the target of intense urban development, including replacement of natural habitats with residential areas, which may have influenced its population dynamics.

Abstract Currently, amphibians are recognized as the most threatened vertebrate group worldwide. In this context, studies that offer tools for amphibian conservation are strategic to reduce the threats to this group. The absence of detailed descriptions and morphological variation of the anuran larval stage and the lack of identification tools increase the difficulty of anuran larval stage identification by non-specialists. Here we present the morphological characterization of tadpoles of 49 anuran species that occur in the Cerrado biome and transitional areas. Also, we compared our characterization with available descriptions of the tadpole and provided comments about the morphological variation found in our samples. Finally, we produced a taxonomic key as a tool for species identification using the anuran larval stage.

Abstract The Earth has undergone numerous geological and biological changes over billions of years. The evolution of plants and animals had a direct relationship with the elements’ changes in the atmosphere and the development of the biogeochemical cycles on Earth. The Anthropocene is the age of the Homo sapiens leaves its geological signature on the planet. Human domination and/or interference in the biogeochemical cycles results in an environmental change that affects not only ecosystems, in general, but also the biota and global biodiversity. In this way, we are creating another mass extinction event, the “sixth extinction wave” as well as transforming the ecosystems’ functions and services.
