The recognition of cryptic diversity within geographically widespread species is gradually becoming a trend in the highly speciose Neotropical biomes. The statistical methods to recognise such cryptic lineages are rapidly advancing, but have rarely been applied to genomic-scale datasets. Herein, we used phylogenomic data to investigate phylogenetic...

Species delimitation is the process of distinguishing between populations of the same species and distinct species of a particular group of organisms. Various methods exist for inferring species limits, with most of them being rooted in Coalescent Theory. Their primary goal is to identify independently evolving lineages that should represent separa...

Aim To investigate the influence of ecological factors, geologic and climatic history on current diversity patterns of bat communities. We predicted that (i) our three different biodiversity dimensions (species richness, functional and phylogenetic diversity) will have a positive relationship with habitat heterogeneity; (ii) variation in phylogene...

DNA barcoding and environmental DNA (eDNA) represent an important advance for biomonitoring the world's biodiversity and its threats. However, these methods are highly dependent on the presence of species sequences on molecular databases. Brazil is one of the largest and most biologically diverse countries in the world. However, many knowledge gaps...

Wedell & Kemp (2024) examined the importance of female sexual preferences for male UV reflectance on offspring viability and the evolution of male traits in the butterfly Eurema hecabe. Female preferences were found to have multiple consequences, including increased trait value, higher offspring viability, and reduced mutational load. These finding...

Mirinaba curitybana (Lange de Morretes, 1952) is a Brazilian endemic land snail restricted to the surroundings of the city of Curitiba, Paraná state. Among the very few mentions of the species available in the scientific literature, there are three different spellings of the stem of its specific epithet. To address and solve this long-standing issu...

Rivers can be difficult barriers for animals to cross, especially animals that cannot swim or fly. The Amazon region has many of the largest rivers in the world, which limits the movements of many animals that cannot cross them. Thus, some animal species occur on one side of a river but not on the other side. Isolation of animal species caused by r...

Birds are highly visually oriented and use plumage coloration as an important signalling trait in social communication. Hence, males and females may have different patterns of plumage coloration, a phenomenon known as sexual dichromatism. Because males tend to have more complex plumages, sexual dichromatism is usually attributed to female choice. H...

Mirinaba cadeadensis Lange de Morretes, 1952 is restricted to the Paraná state, and found at the municipalities of Morretes, São José dos Pinhais, Paranaguá, Matinhos, and Guaratuba, associated to the Serra do Mar mountains. In this paper, we report the first record of this species in an anthropogenic shell mound. Two shells of M. cadeadensis were...

The Brazilian Cerrado is considered a biodiversity hotspot highly threatened by human activities. Recently, many studies have demonstrated how underestimated is Cerrado’s biodiversity considering squamate species, and the identification of divergent and cryptic lineages is essential for the formulation of effective conservation strategies. The tran...

Vector-borne parasites are important ecological drivers influencing life-history evolution in birds by increasing host mortality or susceptibility to new diseases. Therefore, understanding why vulnerability to infection varies within a host clade is a crucial task for conservation biology and for understanding macroecological life-history patterns....

Sambaquis são sítios arqueológicos pré-históricos, constituídos na sua maior parte por conchas de moluscos, formando colinas que podem alcançar mais de 30 metros de altura. São encontrados em todo o litoral brasileiro, e no Estado do Paraná centenas destes sítios foram catalogados a partir da década de 1940. Neste trabalho, apresentamos um primeiro...

The Dekeyser's nectar bat (Lonchophylla dekeyseri) is a cave roosting bat endemic to the Brazilian Cerrado that is considered endangered according to the IUCN Red List. Even though it is likely highly threatened, there is no current assessment of its conservation status or the conservation of the caves within its distribution. Additionally, a chang...

The Amazon comprises many of the largest rivers in the planet and also houses some of the richest bat communities in the world. Rivers are important geographic barriers for the dispersal and distribution of different taxa worldwide and, particularly in the Amazon region, they form the conceptual and empirical bases for the recognition of the so-cal...

Coral snakes in the genus Micrurus are venomous, aposematic organisms that signal danger to predators through vivid coloration. Previous studies found that they serve as models to several harmless species of Batesian mimics. However, the extent to which Micrurus species engage in Müllerian mimicry remains poorly understood. We integrate detailed mo...

Brazil’s government has changed the designation of caves that warrant top priority for conservation (see go.nature.com/3gy5). Constituting some 13–30% of the country’s 22,000 protected caves, these will now be open to commercial exploitation, which could seriously affect their vulnerable fauna. The expansion of the mining sector, driven partially...

Neste trabalho, desenvolvemos e aplicamos dois ma- teriais didáticos digitais (vídeo e folder) que podem auxiliar na desconstrução do pensamento teleológico e da ideia da hierarquia evolutiva em sala de aula, e ve- rificamos sua eficiência em uma situação experimen- tal alheia à sala de aula. Buscamos abordar conceitos básicos de evolução biológica...

Historical variations in climate and landscape configuration are the main aspects known to generate and maintain diversity. Taxa associated with open habitats within broader forest contexts are often overlooked in studies of Neotropical biogeography. We investigated the evolutionary and demographic history of lizards in the Cnemidophorus lemniscatu...

Habitat selection has long been a central theme in ecology and has historically considered both physiological responses and ecological factors affecting species establishment. Investigating habitat selection patterns at different scales can provide important information on the relative roles of the environmental factors influencing the organisms’ a...

Resumo: A região neotropical se destaca pela elevada diversidade taxonômica, funcional, genética e filogenética dos anfíbios e répteis (herpetofauna). Múltiplos eventos geológicos e evolutivos, atuando de modo sinérgico com processos ecológicos ao longo do tempo, deram origem aos padrões de distribuição da herpetofauna que observamos ao longo dos v...

Savanna tree communities occurring in confluence zones with other biomes likely experience different environmental pressures, resulting in shifts in the selection of individual traits, the combinations of such traits, and species composition. In seasonally dry fire-prone environments, plant survival is presumably associated with adaptive changes in...

In this work, we develop and apply two digital materials (video and folder) wich can help on debuilding the teologic bealives and evolutionary hierarchy inside classrooms. Also, its efficiency has been verified in an experimental situation outside the classroom. We seek to approach basic concepts of biological evolution, explicitly dealing with the...

Dispersal‐associated traits—such as flight ability—influence how species move across the landscape, and can dramatically impact their distributions and patterns of genetic structure. Ortego et al. (2021) examine genomic data from two recently diverged alpine grasshopper lineages with distinct wing sizes to assess the demographic impacts of flight l...

Mimicry can directly affect the evolutionary history of models, mimics, and signal receivers. Mimics often use multimodal signaling in order to deceive receivers. Jamie et al. (2020) showed that brood parasitic birds display multimodal signaling of mimetic traits triggered by sexual and filial imprinting on host species. These resulting adaptations...

Traditionally focused on Amazonian and Atlantic rainforests, studies on the origins of high Neotropical biodiversity have recently shifted to also investigate biodiversity processes in the South American dry diagonal, encompassing Chaco, Cerrado savannas and Caatinga seasonally dry tropical forests. The plateau/depression hypothesis states that rip...

Aim Understanding where and why species diversity is geographically concentrated remains a challenge in biogeography and macroevolution. This is true for the Cerrado, the most biodiverse tropical savanna in the world, which has experienced profound biodiversity loss. Previous studies have focused on a single metric (species composition), neglecting...

Questions What are the trade‐offs and/or associated syndromes within and between fire‐associated traits? Does bud protection relate to bark properties and tree resprouting ability? Which traits will influence post‐fire tree survival (mortality rate and top‐kill) and tree recovery (canopy recovery and resprouting volume)? Do species with different l...

We describe a new species of Enyalius endemic to the Brazilian Cerrado, based on morphological and molecular data sets. In the face of uncertain taxonomy among museum specimens of Enyalius, we used a novel analytical approach based on Gaussian mixture modeling for species assignments. We also used a machine-learning classification procedure (random...

Semiochemical dispersion-based communication is a determinant in squamate behaviour and reproduction. This communication mode is driven by different scent glands and is distributed widely among squamate lineages. However, most studies of such communication have focused on femoral glands, and there is little literature about semiochemical-based comm...

Species complexes are common in the Neotropical flora, and the Pagamea guianensis complex is one of the most widespread groups of species in the Amazonian white-sand flora. Previous analyses suggested the occurrence of ten species in this group, but species limits remained unclear due to poor sampling, morphological overlap and low molecular variat...

Pygmy perches (Percichthyidae) are a group of poorly dispersing freshwater fishes that have a puzzling biogeographic disjunction across southern Australia. Current understanding of pygmy perch phylogenetic relationships suggests past east–west migrations across a vast expanse of now arid habitat in central southern Australia, a region lacking conte...

Phylogenomics and species delimitation of pygmy perches (Teleostei: Percichthyidae): implications for biogeography, taxonomy and conservation

Communal nesting occurs in many reptile species. The hypotheses that explain the evolution of such behaviours are still controversial, but will be better understood as more communal nesting records are described in the literature. We report the findings of two communal nests of Phyllopezus pollicaris, including the largest known nest for the specie...

Species range limits often fluctuate in space and time in response to variation in environmental factors, and to gradual niche evolution due to changes in adaptive traits. We used genome-wide data to investigate evolutionary divergence and species range limits and in a generalist and highly dispersive fish species that shows an unusually wide distr...

Several mistletoe species are able to grow and reproduce on both deciduous and evergreen hosts, suggesting a degree of plasticity in their ability to cope with differences in intrinsic host functions. The aim of this study was to investigate the influence of host phenology on mistletoe water relations and leaf gas exchange. Mistletoe Passovia ovata...

Habitat selection is one of the main factors influencing life-history evolution in animals, and is especially relevant for amphibians that must avoid desiccation. In environments such as the Brazilian restinga, where freshwater is scarce, bromeliads can provide suitable microhabitats and be an important determinant of amphibian diversity. Here, we...

We present the first records of Tropidurus callathelys and T. chromatops in Brazil, at Parque Estadual Serra Ricardo Franco, Mato Grosso. The two species are largely syntopic and associated with rock outcrops on the plateaus of the Serranía de Huanchaca, Bolivia and Brazil. Tropidurus callathelys is more abundant, more heliophilous and uses vertica...
