The Maguari Stork (Ciconia maguari) is one of the three species of the family Ciconiidae that occur in South America. Despite abundant in landscapes dominated by wetlands and grasslands, detailed studies on its biology are scarce. This study is aimed at investigating aspects of the breeding of Maguari Storks in Brazil. Photographic records were searched in the WikiAves database. A total of 65 records, obtained by citizens along 13 years in 32 municipalities, showed evidences of breeding activities in Brazil. Most (86%) of these records were gathered in the Pampa biome, in southern Brazil. Nests were large platforms and contained 1-3 young. Nests built on the ground were in grasslands or reed patches. Those built on shrubs were at boundaries between lakes and grasslands, and were often in colonial nesting sites with egrets and herons. Incubation occurred between July and November, and nestlings were found between August and December. Juveniles able to fly were recorded between late October and February. Most records of breeding activities were obtained at sites located < 300 m above sea level. As the Maguari Stork is a conspicuous and charismatic species, its conservation could substantially benefit from the awareness of landowners to promote eco-tourism in their properties, attracting birdwatchers. For this, it should be ensured the integrity of grasslands, marshes, and lakes with microhabitats often used for nesting (woody plants and reed patches).

In Colombia, few studies have focused on nest architecture, behavior or sociality of wild bees. This study provides basic information on the nests of Caenohalictus alexandrei and presents behavioral observations outside the nests, derived from direct field observation of 40 nests and 39 male sleeping cavities in two localities of the Savanna of Bogota, Colombia. We recognized four different behavioral activities carried out by adult females: foraging, guarding, opening and closing of the entrance of the nest, with foraging being the most frequent of them. The observed activities were carried out more frequently from 9:00 h to 13:00 h. Males were observed performing two behavioral activities in the sleeping cavities: staying at the cavity entrance and cavity departure. A third male activity, corporal grooming, was carried out outside the sleeping cavity. Our field observations indicate that more than one adult female was active simultaneously performing the different tasks within a single nest. The nests presented different levels of complexity in their architecture, depending on the age of the nest and number of adult females in them. Descriptions of the nesting sites and behavioral activities as well as illustrations of the nest architecture are provided.

The present study catalogues exotic and allochthonous fish species found in the three main freshwater river drainages of Rio Grande do Sul State using records of scientific collections and literature, and discusses the main impacts caused by their introduction in natural environments. Ten exotic species are found in the area, i.e., Clarias gariepinus, Coptodon rendalli, Ctenopharyngodon idella, Cyprinus carpio, Hypophthalmichthys molitrix, Hypophthalmichthys nobilis, Ictalurus punctatus, Micropterus salmoides, Oncorhynchus mykiss and Oreochromis niloticus, belonging to five orders, nine genera and seven families. These fishes are native from African, Asian, European and North American countries. The eight allochthonous species, i.e., Acestrorhynchus pantaneiro, Hoplerythrinus unitaeniatus, Hoplias lacerdae, Megaleporinus macrocephalus, Piaractus mesopotamicus, Pachyurus bonariensis, Serrasalmus maculatus, and Trachelyopterus lucenai, belong to three orders, eight genera, and six families, are native from the Río La Plata basin, that includes the Río Uruguay, and have been all registered in the Laguna dos Patos. Two of these species are further recorded in the Rio Tramandaí system (A. pantaneiro and T. lucenai). The study also presentes a brief history of the first records of exotic species in the state and in the country, and their main vectors of introduction. According to the records of exotic species in scientific collections, the two exotic species with the highest number of records in the country are tilapias Coptodon rendalii (508 records) and Oreochromis niloticus (376 records), and most records occurred in the last two decades. The two carps Cyprinus carpio and Ctenopharyngodon idella are the only exotic species recorded in the three main drainage basins of the state. In addition, we warn about the importance of studies about the biology and negative impacts of exotic species over native species on the understanding of management in wild environments.

The emperor tamarin, Tamarinus imperator, is composed of two subspecies, the nominal type, T. i. imperator, distributed between the Acre and Purus Rivers, whose range is limited between the Brazilian state of Acre and Peru are unbounded, and T. i. subgrisescens, occurring in Peru, Bolivia, and Brazil, in the Brazilian states of Acre and Amazonas. Morphologically, both taxa are easily identifiable by the pelage pattern (chromogenetic fields), and even being easily distinguishable, both lineages are considered subspecies according to the criterion based on the Biological Concept of Species from the 1970s, even without presenting some necessary criteria, such as the intergradation zone. Here we analyzed pelage traits, cranial morphometry, Cytochrome-b divergence, and distributional pattern data applying the premises of integrative taxonomy to elucidate the taxonomic status of both lineages. We hypothesize that both lineages are considered full species through a series of criteria for species recognition, such as distinguishability, level of phenotypical divergences of several morphological complexes with congruence among them, and some genetic divergence. The hybridization is unknown and the low or the lack of sampling in target areas does not allow us to determine whether a hybridization or even contact zone between the two lineages exists indeed. All character sets analyzed were congruent with each other and reinforced the high level of divergences between the two subspecies including several pelage differences, morphometry (descriptive statistics, PCA, and MANOVA), and mitochondrial DNA Cytochrome-b divergence. Most of the distribution in both lineages are allopatric, and the levels of intra-lineage phenotypical variation are much lower than between the lineages.

Plastic pollution represents a threat to marine ecosystems and has therefore been gaining space in the realm of public interest. In this study, we investigated the ingestion of food and non-food items (i.e., plastic particles) by fish and crabs. These animals are commonly collected by trawling with a double-ring net along the coast of Cananéia, state of São Paulo, Brazil; some of them are consumed as food by the local population. Fish and crab stomachs were removed and dissected, and their contents were examined under a stereoscopic microscope with an image-capturing system. The presence or absence of plastic was also registered. We examined 139 specimens of 16 fish species and 143 specimens of four crab species. The most frequent food items found in fish were unidentified food, followed by crustaceans, molluscs, polychaetes, and other fish; in crabs, the items were unidentified food, followed by crustaceans, molluscs and fish. Plastic particles were found in all fish species, representing 47.5% of the individuals analysed. In crabs, the incidence of plastic was lower, occurring in only two species (5% in Callinectes danae and 3% in C. ornatus). Only four fish species analysed had previous records of plastic ingestion in the scientific literature. The high incidence of microplastics in our study is worrying because they negatively affect the animals’ lives and can be transferred through the tropic web to top predators, including humans, through the ingestion of contaminated animals.

A taxonomic revision is presented of the genus Paracanthopoma, probably the least-known vandelliine genus at present. The work is based on most of the material available in museums worldwide and includes a major expansion in the knowledge about the genus. Paracanthopoma is circumscribed as a monophyletic group on the basis of nine putatively synapomorphic characters. Evidence is provided for Paracanthopoma and Paravandellia as sister groups and the two genera are comparatively diagnosed. A total of 13 species are recognized in Paracanthopoma, of which nine are new and one is transferred from Paravandellia: Pc. ahriman, new species, Pc. alleynei (Henschel et al., 2021), Pc. carrapata, new species, Pc. cangussu Henschel et al., 2021, Pc. capeta, new species, Pc. daemon, new species, Pc. irritans, new species, Pc. malevola, new species, Pc. parva Giltay, 1935, Pc. saci Dagosta & de Pinna, 2021, Pc. satanica, new species, Pc. truculenta, new species, and Pc. vampyra, new species. Different species display a high degree of phenotypic divergence and are diagnosed on the basis of traditional as well as new morphological characters of both external and internal anatomy. Geographical distributions are mapped for each species and an identification key is provided. Preliminary evidence suggests the existence of four main subclades within Paracanthopoma. The first one includes Pc. ahriman, Pc. cangussu, and Pc. irritans. A second subclade comprises Pc. carrapata, Pc. daemon, Pc. parva, and Pc. truculenta. A third clade includes Pc. malevola and Pc. satanica and a fourth comprises Pc. alleynei and Pc. vampyra. The last clade lacks some putative synapomorphies of all other members of Paracanthopoma and seems to be the sister group to the rest of the genus. Relationships of Pc. capeta and Pc. saci are not as clear, but some evidence exists for the former being related to the first subclade and the latter to the second subclade.
对Paracanthopoma属进行了分类修订，该属可能是目前已知最少的vandelline属。该作品基于世界各地博物馆中的大部分材料，并对该属的知识进行了重大扩展。根据9个假定的突触形态特征，副斑蝥被界定为一个单系群。为Paracanthopoma和Paravandellia作为姐妹群提供了证据，并对这两个属进行了比较诊断。Paracanthopoma共识别出13个物种，其中9个是新物种，1个从Paravandellia转移而来：Pc.ahriman，新种，Pc.alleyeni（Henschel et al.，2021），Pc.carrapata，新种。，2021，卡佩塔，新种，守护进程，新种，刺激物，新种，马来虫，新种，细小虫，吉尔泰，1935，沙奇-达戈斯塔和德-平纳，2021，沙塔尼卡，新种，特鲁昆塔，新种和吸血鬼，新种。不同物种表现出高度的表型差异，并根据外部和内部解剖的传统和新形态特征进行诊断。绘制了每个物种的地理分布图，并提供了识别密钥。初步证据表明副斑蝥体内存在四个主要亚支。第一个子条款包括Pc.ahriman、Pc.cangussu和Pc.irritans。第二子条款包括Pc.carrapata、Pc.daemon、Pc.parva，第三个分支包括马列虫属和沙塔虫属，第四个分支包括阿氏虫属和瓦姆皮拉虫。最后一个分支缺乏Paracanthopoma所有其他成员的一些假定的突触形态，似乎是该属其他成员的姐妹群。capeta和saci的关系并不清楚，但有一些证据表明前者与第一款有关，后者与第二款有关。

The work is based on most of the material available in museums worldwide and includes a major expansion in the knowledge about the genus. Paracanthopoma is circumscribed as a monophyletic group on the basis of nine putatively synapomorphic characters. Evidence is provided for Paracanthopoma and Paravandellia as sister groups and the two genera are comparatively diagnosed. A total of 13 species are recognized in Paracanthopoma, of which nine are new and one is transferred from Paravandellia: Pc. ahriman, new species, Pc. alleynei (Henschel et al., 2021), Pc. carrapata, new species, Pc. cangussu Henschel et al., 2021, Pc. capeta, new species, Pc. daemon, new species, Pc. irritans, new species, Pc. malevola, new species, Pc. parva Giltay, 1935, Pc. saci Dagosta & de Pinna, 2021, Pc. satanica, new species, Pc. truculenta, new species, and Pc. vampyra, new species. Different species display a high degree of phenotypic divergence and are diagnosed on the basis of traditional as well as new morphological characters of both external and internal anatomy. Geographical distributions are mapped for each species and an identification key is provided. Preliminary evidence suggests the existence of four main subclades within Paracanthopoma. The first one includes Pc. ahriman, Pc. cangussu, and Pc. irritans. A second subclade comprises Pc. carrapata, Pc. daemon, Pc. parva, and Pc. truculenta. A third clade includes Pc. malevola and Pc. satanica and a fourth comprises Pc. alleynei and Pc. vampyra. The last clade lacks some putative synapomorphies of all other members of Paracanthopoma and seems to be the sister group to the rest of the genus. Relationships of Pc. capeta and Pc. saci are not as clear, but some evidence exists for the former being related to the first subclade and the latter to the second subclade.","PeriodicalId":35345,"journal":{"name":"Papeis Avulsos de Zoologia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49208060","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Brazilian Atlantic Forest is considered one of the most threatened tropical forests in the world due to the extensive environmental impact it has endured throughout history. Only 12.4% of its original vegetation is estimated to remain. Even though reduced and highly fragmented, it houses enormous biodiversity, and its preservation is paramount to the maintenance of the country’s fauna, flora, funga and microbiota. One of the most efficient measures adopted by public agencies aimed at protecting biodiversity has been the creation of conservation units. To evaluate the preservation state of protected areas, several environmental studies have been performed; species inventories are one among them. Ants are excellent bioindicators, for they are not only sensitive to environmental changes, but they also have a history of being used in impact assessment (i.e., fragmentation). In this study we assessed the ant communities inhabiting the leaf litter in areas with different regeneration states at the RPPN Botujuru – Serra do Itapety (Mogi das Cruzes, São Paulo – Brazil). Mini-Winkler traps were used in the ant survey, and diversity analyses were performed. In total, we recorded 86 species of ants, with a highlight to Camponotus cillae Forel, 1912, a species that remained unrecorded for the state of São Paulo for over 100 years, and a possible new species of Octostruma Forel, 1912. Overall, the species found show that the areas are in the process of natural regeneration. Our data on RPPN Botujuru is unprecedented, and our species list has the potential of being used as an effective monitoring tool for this conservation unit.
巴西大西洋森林被认为是世界上最受威胁的热带森林之一，因为它在历史上经历了广泛的环境影响。据估计，只有12.4%的原始植被仍然存在。尽管数量减少且高度分散，但它拥有巨大的生物多样性，保护它对维护该国的动物群、植物群、真菌群和微生物群至关重要。公共机构为保护生物多样性而采取的最有效措施之一是建立保护单位。为了评估保护区的保存状况，进行了几项环境研究;物种清单就是其中之一。蚂蚁是一种优秀的生物指标，不仅对环境变化敏感，而且在影响评价(即破碎化)中也有应用的历史。在这项研究中，我们评估了Botujuru - Serra do Itapety RPPN (Mogi das Cruzes, s o Paulo - Brazil)不同更新状态下落叶凋落物的蚂蚁群落。采用微型温克勒捕集器进行蚁群调查，并进行蚁群多样性分析。我们总共记录了86种蚂蚁，其中最值得注意的是在圣保罗州未被记录100多年的Camponotus cillae Forel, 1912年，以及一种可能是新物种的Octostruma Forel, 1912年。总的来说，发现的物种表明该地区正处于自然更新的过程中。我们关于Botujuru的数据是前所未有的，我们的物种清单有可能被用作这个保护单位的有效监测工具。
