The Black Skimmer (Rynchops niger) and the Large-billed Tern (Phaetusa simplex) are two migratory waterbirds that breed simultaneously on many river beaches in South America. Both are polytypic taxa with little information about the distribution and nonbreeding (“wintering”) areas. Based on data from the literature, citizen science websites, fieldwork, and specimens housed in natural history museums, we revised the distribution of some of the main breeding colonies in South America, comparing it with continental rainy cycles to identify generalities about the role of precipitation seasonality on the defining intratropical migration routes of these species. Our data suggest that the seasonal precipitation cycle of South America directly influences the reproductive timing and distribution of both species, which is largely circumscribed by South America’s rivers. After breeding on sandy beaches during the dry season, both species disperse in small groups or even individually – not in large flocks as seen in breeding areas – making it difficult to find general migration patterns during the rainy season. Nonetheless, individuals of both species tend to follow the course of the largest rivers of the continent and even alternative routes to disperse into several areas throughout South America during the nonbreeding season.

This study presents the first record of the cordiform echinoid Plagiobrissus grandis (Gmelin, 1791) (Echinoidea: Spatangoida: Brissidae) in Paraná’s shallow inner shelf, in addition to a brief description of its location, body measurements, sex determination, and reproductive status. Two specimens were recorded between 2015 (bycatch by artisanal fishing) and 2016 (observed by scuba diving). The only specimen – with severe signs of weakness – captured was donated to Associação MarBrasil and kept in an aquarium for rehabilitation (8 days), where it was possible to observe digging movements, burying skills (partially), and camouflage or covering behavior. The organism was sent to the UNESPAR campus of Paranaguá and was photographed, measured (length: 155.65 mm, width: 118.93 mm, and maximum test height: 41.31 mm), fixed, and properly preserved. Digitized images of the histological preparation showed that it was a female in the recovery stage (or nutritional reserve) of the reproductive cycle. Regardless of their limitations, the current records for the Brissidae family in South Atlantic are still concentrated on the Brazilian coast, contributing to the understanding of zoogeographic, ecological, morphophysiological, and behavioral aspects of the spatangoid echinoids.

In xeric environments, such as Caatinga Biome, habitat characteristics such as phytophysiognomy type and presence of water bodies can represent higher resource availability. In this context, the present study investigated the effect of phytophysiognomies and presence of water bodies in the abundance and community structure of medium and large mammal species (MLM) in the Serra de Santa Catarina, Paraíba, Brazil. To evaluate these variables we conduct an effort of 373 camera-trap days, between August 2012 and November 2014. We recorded 12 MLM species, distributed in six orders and 11 families. From those, Kerodon rupestris is the only one listed in the Brazilian List of Threatened Fauna. Regarding the habitat, the Mann-Whitney showed a significant higher frequency to the Shrubby habitat and the ANOSIM showed no shifts in the community structure between Arboreal and Shrubby. Concerning the presence of water bodies, both the Mann-Whitney and the ANOSIM showed significant higher frequency to the habitat with water presence. We observed that both phytophysiognomy and water bodies are important variables which affect mainly the abundance of mammalian species from semiarid environments. Nonetheless, whereas the forest remnants get smaller the existence of water bodies becomes a preponderant factor to the MLM species and its community structure.

Pantophthalmidae (Diptera) are recorded exclusively in the Neotropical Region. Despite the large size of adults, their species are often rare and poorly represented in entomological collections. Only two genera and 20 species are known, of which 12 are recorded in the five regions of Brazil. In the North region, the family is reported from all states, except in Tocantins. The present work provides the first records of the family for Tocantins, expanding the distribution of two species, Pantophthalmus kerteszianus (Enderlein, 1914) and P. tabaninus Thunberg, 1819. Both species are recorded for the first time in the Cerrado biome. In addition, we provide photographs of the species and a distribution map.

Leurus Townes, 1946 is a small genus of Metopiinae (Hymenoptera: Ichneumonidae), consisting of 13 described species distributed in the Neotropics and the Nearctic region. The present work aims to contribute to the taxonomic knowledge of Leurus in Brazil. A total of 109 specimens were identified and 15 literature records were analyzed. The genus geographical occurrence was evaluated according to data obtained from the literature and labels of analyzed specimens. Five species of Leurus were identified for the Brazilian fauna: L. angustignathus, L. caeruliventris, L. discus, L. gracius and L. nostrus. New municipality records of occurrence were made for L. angustignathus in the state of São Paulo, L. caeruliventris in the states of Bahia, Distrito Federal, Mato Grosso, Mato Grosso do Sul, Minas Gerais, Paraná, Piauí and Rondônia; for, L. discus in the state of Alagoas and São Paulo, and L. gracius in the state of Minas Gerais, Rio de Janeiro, and São Paulo. Females of L. angustignathus and L. gracius were described for the first time in the present study. The genitalia of males of L. caeruliventris, L. discus and L. gracius were described and illustrated for the first time.

Fire might occur under natural conditions in the Pantanal of Brazil; however, with climate change, severe periods of drought potentiated the devasting fires in 2020, resulting in substantial wildlife loss. Considering that mammal communities are strongly affected by fire and habitat alterations, the aim of this study was to evaluate possible differences in mammal diversity and the number of records before and one year after the fire in one region of the Pantanal of Mato Grosso, Brazil (Parque SESC Baía das Pedras – PSBP). The data collection was performed using camera trapping between 2015 and 2017 and 2021, together with visual field observations in PSBP. We observed that the mammal assemblage composition was similar before and one year after the fire. Four species were more or less frequent in burned areas than in unburned ones. Since the fire was controlled in this area, avoiding its total destruction, and the species that fled from the surrounding areas, which were completely burnt, might be using PSBP as a refuge while the vegetation recovers elsewhere. Therefore, the PSBP might have contributed to protecting mammal species after the fire and maintaining and conserving biodiversity on a regional scale in the Pantanal of Mato Grosso, Brazil.
巴西潘塔纳尔自然条件下可能发生火灾；然而，随着气候变化，严重的干旱加剧了2020年毁灭性的火灾，导致野生动物大量损失。考虑到哺乳动物群落受到火灾和栖息地变化的强烈影响，本研究的目的是评估巴西马托格罗索潘塔纳尔一个地区火灾前后哺乳动物多样性和记录数量的可能差异（Parque SESC Baía das Pedras–PSBP）。数据收集是在2015年至2017年至2021年间使用相机捕捉以及PSBP中的视野观测进行的。我们观察到，火灾发生前和火灾发生后一年，哺乳动物群落的组成相似。有四种物种在燃烧区比未燃烧区更频繁或更少。由于火灾在该地区得到了控制，避免了其彻底破坏，而从周围地区逃离的物种也被完全烧毁，因此在其他地方植被恢复的同时，可能会使用PSBP作为避难所。因此，PSBP可能有助于在火灾后保护哺乳动物物种，并在巴西马托格罗索的潘塔纳尔地区范围内维护和保护生物多样性。

The Continental African abelisauroid theropod dinosaur fossil record from the Jurassic-Cretaceous periods is becoming increasingly better understood, and offers great insight into the evolution and biogeography of this long-lived group of carnivores. Abelisauroidea is among the most familiar groups of theropod dinosaurs from Gondwana, with fossil records in South America, Australia, India and Africa, along with Europe. The objective of the present study is to review the fossil record of abelisauroids in continental Africa. Based on the literature and records from the online databases “The Paleobiology Database” and “The Theropod Database”, we review the distribution of these theropods in Africa and comment on their evolution. The African continent is a major region of importance when it comes to 26 Abelisauroidea fossil findings, including records of both major subdivisions of the clade: the Abelisauridae and Noasauridae families. The oldest Abelisauroidea fossil record found in Africa dates from the Late Jurassic, while the final records date from the end of the Cretaceous. This indicates that clade was the longest surviving lineage of the large theropods of Africa, and they filled a variety of ecological roles, including apex predators, at the end of the Cretaceous, when tyrannosaurids occupied similar niches in the northern continents.

Aniara sepulchralis specimens sampled at different locations (Belém and Bragantina microregions) show differences in size of some morphological structures such as head width, pronotum width, distance between eyes, pronotum base width, labral length, labral width, and spur of the third pair of legs. These changes may be due to biotic, abiotic, and structural factors peculiar to each environment. Differences in structures and morphological measurements of males and females of Aniara sepulchralis were observed, characterized as sexual dimorphism in relation to their teeth and labral-clypeal suture. Females present apical teeth and rectilinear suture, whereas males present a more rounded shape in both teeth and the labral-clypeal suture. Regarding measurements, females have greater body length, head width, eye distance, pronotum length, pronotum width, labral length, and pronotum base width than males.

Two new species of Asphondylia inducing galls on Asteraceae are described, A. gaucha from the state of Rio Grande do Sul and A. mineira from the state of Minas Gerais. Their host plants are Vernonanthura discolor (Sprengel) H. Rob., and V. polyanthes (Sprengel) Vega & Dematteis, respectively, both native to Brazil. Illustrations of relevant morphological characters are provided. The new species are compared with congeneric Neotropical species. The types are deposited in the Entomological Collection of the Museu Nacional/Universidade Federal do Rio de Janeiro.
