José Alexandre Felizola Diniz-Filho, Ana Santos, Elisa Barreto, Felipe Naves, Wanderson Santos, Kelly Souza, Rejane Santos-Silva, Ricardo Dobrovolski, Thannya Soares, Rosana Tidon, Zander Spigoloni, Thiago Rangel, Pasquale Raia, Joaquín Hortal & Lucas Jardim
Aim: The Island Rule – i.e. the tendency for body size to decrease in large mammals and increase in small mammals on islands has been commonly evaluated through macroecological or macroevolutionary, pattern-orientated approaches, which generally fail to model the microevolutionary processes driving either dwarfing or gigantism. Here, we seek to identify which microevolutionary process could have driven extreme insular dwarfism in the extinct dwarf red deer population on the island of Jersey. Location: Jersey, UK...

Identifying traits that enable lizard adaptation to different habitats

Flávia Lanna, Guarino Colli, Frank Burbrink & Bryan Carstens
Aim: Species adapt differently to contrasting environments, such as open habitats with sparse vegetation and forested habitats with dense forest cover. We investigated colonization patterns in the open and forested environments in the Diagonal of Open Formations and surrounding rain forests (i.e., Amazon and Atlantic Forest) in Brazil, tested whether the diversification rates were affected by the environmental conditions, and identified traits that enabled species to persist in those environments. Location: South America, Brazil. Taxon:...

Data from: Evolutionary constraints on tree size and aboveground biomass in tropical dry forests

Natalia De Aguiar-Campos, Fernanda Coelho De Souza, Vinícius Maia, Vanessa Rezende, Cléber Souza, Gabriela Paula, Paola Santos, Gisele Menino, Wilder Silva & Rubens Santos
1. The extent (or lack) of phylogenetic signal for key ecological traits reveals the role of evolutionary processes on present-day ecosystem function and hints on future ecological trends under climate change scenarios. This approach has been applied to South American tropical moist forests, but not to the highly threatened seasonally dry tropical forests (SDTF), despite acknowledgement of their unique evolutionary history. To fill this knowledge gap, we investigated the legacy of evolutionary processes on vital...

Tim Jones, H Günther, Sue Brownill, Ramin Keivani, I Neto, E D'Orsi, Ben Spencer, J Vargas & G Butina-Watson
The Healthy Urban Mobility (HUM) project was a study to understand the impact of everyday (im)mobility on health and wellbeing with a variety of social groups living in different neighbourhoods in Brazil and the UK, and also to explore the potential for participatory mobilities planning with local communities to support and develop solutions for healthy urban mobility.

Data and scripts from: Phylogenomic analysis points to a South American origin of Manihot and illuminates the primary gene pool of cassava

Marcelo F. Simon, J. Moises Mendoza F., Márcio Lacerda Lopes Martins, Sergei V. Drovetski, Natalia A. S. Przelomska, Hope Loiselle, Taciana B. Cavalcanti, Peter W. Inglis, Natalie G. Mueller, Robin G. Allaby, Fábio De Oliveira Freitas & Logan Kistler
The genus Manihot, with around 120 known species, is native to a wide range of habitats and regions in the tropical and subtropical Americas. Its high species richness and recent diversification only ~6Mya have significantly complicated previous phylogenetic analyses. Several basic elements of Manihot evolutionary history therefore remain unresolved. Here, we conduct a comprehensive phylogenomic analysis of Manihot, focusing on exhaustive sampling of South American taxa. We find that two recently described species from northeast...

Precipitation, water level and descriptive statistics

Marcelo Medeiros, Marcelo Simon, Washington Oliveira & Pamela Moser
Extreme weather events and the presence of mega-hydroelectric dams, when combined, present an emerging threat to natural habitats in the Amazon region. To understand the magnitude of these impacts, we used remote sensing data to assess forest loss in areas affected by the extreme 2014 flood in the entire Madeira River basin, the location of two mega-dams. In addition, forest plots (26 ha) were monitored between 2011 and 2015 (14,328 trees) in order to evaluate...

Shaped by the sun: the effect of exposure to sunlight on the evolution of spider bodies

Leonardo Ferreira-Sousa, Pedro N. Rocha, Paulo C. Motta & Felipe Gawryszewski
Body temperature strongly influences fitness. Some sun-exposed ectotherms thermoregulate by adjusting body posture according to the sun's position. To evaluate the impact of body shape, size and posture on body temperature, we first built a model combining traditional heat transfer models with models of thermoregulatory postures in spiders. The model indicates that both body size and shape determine thermoregulation efficiency by affecting heat gain via solar irradiance. These estimates corroborate previous empirical studies on spider...

Mullerian mimicry and the colouration patterns of sympatric coral snakes

Renan Bosque, Chaz Hyseni, Maria Luiza Gonçalves Santos, Eduardo Rangel, Camila Juliana Da Silva Dias, Jacob Hearin, , Fabricius Maia, Guarino Colli & Brice Noonan
This dataset cointains data used for the study of Müllerian mimicry in coral snakes. Coral snakes in the genus Micrurus are venomous, aposematic organisms that signal danger to predators through vivid colouration. 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 morphological and geographical distribution data to investigate if coral snakes are...

Philornis parasitism: impact on nestlings and risk factors involved

Carlos Biagolini-Jr. & Regina H. Macedo
Parasitic botfly larvae (Philornis ssp., Diptera: Muscidae) are found in nests of several bird taxa, although prevalence and nestling tolerance vary considerably among species. Here we describe patterns of botfly infestation in blue-black grassquit (Volatinia jacarina) nestlings. We identified the most typically affected nestling body parts and assessed parasite prevalence, impact on nestling survival, changes in nestling body shape and mass index. Additionally, we tested whether climatic conditions, nest morphology and habitat characteristics are associated...

Data from: Tropical forests structure and diversity: a comparison of methodological choices

Cléber Rodrigo Souza, Fernanda Coelho De Souza, Vinícius Andrade Maia, Natália Aguiar-Campos, Polyanne Aparecida Coelho, Camila Laís Farrapo, Alisson Borges Miranda Santos, Felipe De Carvalho Araújo, Fernanda Moreira Gianasi, Gabriela Gomes Pires Paula, Jean Daniel Morel, Nathalle Cristine Alencar Fagundes, Paulo Oswaldo Garcia, Wilder Bento Silva, Marco Aurélio Leite Fontes & Rubens Manoel Santos
1. Large-scale data compilation is increasing steadily in tropical forest research, but the lack of standardized methods for data collection limits drawing inference from large datasets and cross-biome analyses. Different inclusion methods and minimum tree diameter threshold are among these varying factors. To tackle this issue, we evaluated how different approaches for tree sampling affects our understanding of diversity and functioning in different tropical vegetation types. 2. We used a unique dataset of 44 inventory...

LT-Brazil: A database of leaf traits across biomes and vegetation types in Brazil

Eduardo Mariano, Taciana Gomes, Silvia Lins, Adibe Abdalla-Filho, Amin Soltangheisi, Maria Araújo, Rodrigo Almeida, Fernanda Augusto, Luiza Canisares, Siglea Chaves, Cristiane Costa, Thaís Diniz-Reis, Leonardo Galera, Melissa Martinez, Maristela Morais, Elen Perez, Lucas Reis, Carla Simon, Silvia Mardegan, Tomas Domingues, Raquel Miatto, Rafael Oliveira, Carla Reis, Gabriela Nardoto, Jens Kattge … & Luiz Martinelli
Motivation: Leaf traits represent an important component of plant functional strategies, and those related to carbon fixation and nutrient acquisition form the leaf economics spectrum. However, observations of functional leaf traits are underrepresented in tropical regions in comparison with those in temperate areas. Brazil, a country with continental scale and vast biodiversity is a timely example, where many biomes are impacted by human activities and climate change. However, leaf traits relevant to understand vegetation responses...

Data from: Putting vascular epiphytes on the traits map

Epiphyte trait data for the paper Hietz et al. 2021 Putting vascular epiphytes on the traits map. Journal of Ecology Plant functional traits impact the fitness and environmental niche of plants. Major plant functional types have been characterized by their trait spectrum, and the environmental and phylogenetic imprints on traits have advanced several ecological fields. Yet very few trait data on epiphytes, which represent almost 10% of vascular plants, are available. We collated >80,000 mostly...

Song varies with latitude, climate, and species richness in a Neotropical bird

Edvaldo Silva-Jr, Pedro Diniz & Regina Macedo
Animals can encode information within acoustic signals, particularly, bird songs can be remarkably complex and can indicate individual identity and quality. Two main sets of hypotheses attempt to explain the evolution of increased birdsong complexity across large-scale geographic ranges: (1) larger acoustic space availability, and (2) greater sexual selection intensity, both of which would favor the evolution of more complex songs at higher latitudes, more seasonal and/or species-poor environments. However, few studies have assessed patterns...

The vocal repertoire of the bearded capuchin (Cebidae: Sapajus libidinosus): implications for understanding the complexity of neotropical primate communication

Carolina Lisboa, Francisco Mendes, Maurício Silveira & Ludmilla Aguiar
Vocal communication is an essential aspect of primate social behaviour. The bearded capuchin Sapajus libidinosus is endemic to Brazil and some studies have described specific vocalisation types for this species; however, there is still no complete description of its vocal repertoire. Thus, this study aimed to describe the vocal repertoire of a group of S. libidinosus living in the Parque Nacional de Brasília (PNB), a protected area in the Cerrado area of Central Brazil. We...

No link between population isolation and speciation rate in squamate reptiles

Sonal Singhal, Guarino Colli, Maggie Grundler, Gabriel Costa, Ivan Prates & Daniel Rabosky
Rates of species formation vary widely across the tree of life and contribute to massive disparities in species richness among clades. This variation can emerge from differences in metapopulation-level processes that affect the rates at which lineages diverge, persist, and evolve reproductive barriers and ecological differentiation. For example, populations that evolve reproductive barriers quickly should form new species at faster rates than populations that acquire reproductive barriers more slowly. This expectation implicitly links microevolutionary processes...
