Data from: Evidence for heterochrony in the cranial evolution of fossil crocodyliforms

Pedro L. Godoy, Gabriel S. Ferreira, Felipe C. Montefeltro, Bruno C. Vila Nova, Richard J. Butler & Max C. Langer
The southern supercontinent of Gondwana was home to an extraordinary diversity of stem-crocodylians (Crocodyliformes) during the Late Cretaceous. The remarkable morphological disparity of notosuchian crocodyliforms indicates that this group filled a wide range of ecological roles more frequently occupied by other vertebrates. Among notosuchians, the distinctive cranial morphology and large body sizes of Baurusuchidae suggest a role as apex predators in ecosystems in which the otherwise dominant predatory theropod dinosaurs were scarce. Large-bodied crocodyliforms, modern...

The field of movement ecology has rapidly grown during the last decade, with important advancements in tracking devices and analytical tools that have provided unprecedented insights into where, when, and why species move across a landscape. Although there has been an increasing emphasis on making animal movement data publicly available, there has also been a conspicuous dearth in the availability of such data on large carnivores. Globally, large predators are of conservation concern. However, due...

Data from: Rare frost events reinforce tropical savanna-forest boundaries

1) The ability of vegetation to ameliorate or exacerbate environmental extremes can generate feedbacks that mediate the distribution of biomes. It has been suggested that feedbacks between vegetation and frost damage may be important for maintaining savanna, particularly at the edge of the tropics. 2) We quantified frost damage and air temperature across a network of 30 permanent plots distributed across tropical savanna-forest boundaries in Brazil during an uncommonly hard frost. 3) Tree cover strongly...

Data from: Anatomy of the vegetative organs, inflorescence axis and pedicel in the Neoregelia bahiana complex (Bromeliaceae): taxonomic and ecological importance

Kleber Resende Silva, Leonardo M. Versieux & Aline Oriani
Delimitation of Bromeliaceae into genera or species is often problematic, as observed for the Neoregelia bahiana complex, distributed throughout the rocky fields of Espinhaço Range, Brazil. Considering that the anatomical characterisation of different organs is potentially important for taxonomic and ecological interpretation of this complex, we analysed roots, stems (stolon), leaves, inflorescence axes (peduncle), and pedicels in individuals from different populations. In all the studied individuals, the roots are composed of velamen, a heterogeneous cortex,...

Data from: Predicted 2100 climate scenarios affects growth and skeletal development of tambaqui (Colossoma macropomum) larvae

Ivã G. Lopes, Thyssia B. Araújo-Dairiki, Juliana T. Kojima, Adalberto L. Val & Maria C. Portella
Climate changes driven by greenhouse gas emissions have been occurring in an accelerated degree, affecting environmental dynamics and living beings. Among all affected biomes, the Amazon is particularly subjected to adverse impacts, such as temperature rises and water acidification. This study aimed to evaluate the impacts of predicted climate change on initial growth and development of an important Amazonian food fish, the tambaqui. We analyzed growth performance, and monitored the initial osteogenic process and the...

Data from: Long-distance pollen and seed dispersal and inbreeding depression in Hymenaea stigonocarpa (Fabaceae: Caesalpinioideae) in the Brazilian savannah

Marcela A. Moraes, Thaisa Y.K. Kubota, Bruno C. Rossini, Celso L. Marino, Miguel L.M. Freitas, Mario L.T. Moraes, Alexandre M. Da Silva, Jose Cambuim & Alexandre M. Sebbenn
Hymenaea stigonocarpa is a Neotropical tree that is economically important due to its high-quality wood; however, because it has been exploited extensively, it is currently considered threatened. Microsatellite loci were used to investigate the pollen and seed dispersal, mating patterns, spatial genetic structure (SGS), genetic diversity, and inbreeding depression in H. stigonocarpa adults, juveniles and open-pollinated seeds, which were sampled from isolated trees in a pasture and trees within a forest fragment in the Brazilian...

Data from: Defaunation and fragmentation erode small mammal diversity dimensions in tropical forests

Ricardo S. Bovendorp, Fernanda T. Brum, Robert A. McCleery, Benjamin Baiser, Rafael Loyola, Marcus V. Cianciaruso & Mauro Galetti
Forest fragmentation and defaunation are considered the main drivers of biodiversity loss, yet the synergistic effects of landscape changes and biotic interactions on assemblage structure have been poorly investigated. Here, we use an extensive dataset of 283 assemblages and 105 species of small mammals to understand how defaunation of medium and large mammals and forest fragmentation change the community composition and diversity of rodents and marsupials in tropical forests of South America. We used structured...

Data from: Moving in the Anthropocene: global reductions in terrestrial mammalian movements

Allen, Nina Attias, Tal Avgar, Hattie Bartlam-Brooks, Buuveibaatar Bayarbaatar, Jerrold L. Belant, Alessandra Bertassoni, Dean Beyer, Laura Bidner, Floris M. Van Beest, Stephen Blake, Niels Blaum, Chloe Bracis, Danielle Brown, P. J. Nico De Bruyn, Francesca Cagnacci, Justin M. Calabrese, Constança Camilo-Alves … & Thomas Mueller
Animal movement is fundamental for ecosystem functioning and species survival, yet the effects of the anthropogenic footprint on animal movements have not been estimated across species. Using a unique GPS-tracking database of 803 individuals across 57 species, we found that movements of mammals in areas with a comparatively high human footprint were on average one-half to one-third the extent of their movements in areas with a low human footprint. We attribute this reduction to behavioral...

Data from: Seasonal flooding, topography, and organic debris interact to influence the emergence and distribution of seedlings in a tropical grassland

Francielli Bao, Tracy Elsey-Quirk, Marco Antonio De Assis, Rafael Arruda & Arnildo Pott
In seasonally flooded wetlands, natural disturbances such as flooding and associated organic debris deposition followed by a drawdown period provide various opportunities for plant species regeneration, which can promote plant community diversity across space and time. Specifically, regeneration may be influenced by the direct effect of flooding on seed dispersal and seedling emergence as well as the indirect effect of organic debris on seed trapping and germination. Our objective was to examine the influence of...

Data from: New insights on water buffalo genomic diversity and post-domestication migration routes from medium density SNP chip data

The domestic water buffalo is native to the Asian continent but through historical migrations and recent importations, nowadays has a worldwide distribution. The two types of water buffalo, i.e., river and swamp, display distinct morphological and behavioral traits, different karyotypes and also have different purposes and geographical distributions. River buffaloes from Pakistan, Iran, Turkey, Egypt, Romania, Bulgaria, Italy, Mozambique, Brazil and Colombia, and swamp buffaloes from China, Thailand, Philippines, Indonesia and Brazil were genotyped with...

Data from: Drivers of individual niche variation in coexisting species

Raul Costa-Pereira, Volker H.W. Rudolf, Franco L. Souza, Marcio S. Araujo & Volker H. W. Rudolf
1. Although neglected by classic niche theory, individual variation is now recognized as a prevalent phenomenon in nature with evolutionary and ecological relevance. Recent theory suggests that differences in individual variation across competitors can affect species coexistence and community patterns. However, the degree of individual variation is flexible across wild populations and we still know little about the ecological drivers of this variation across populations of single species and, especially, across coexisting species. 2. Here...

Data from: Leafing patterns and leaf exchange strategies of a cerrado woody community

Maria Gabriela Gutierrez De Camargo, Gustavo Henrique De Carvalho, Bruna De Costa Alberton, Paula Reys & Leonor Patricia Cerdeira Morellato
The deciduousness of tropical trees and communities depend on ecosystems characteristics such as plant species diversity, and strength of the dry season. Based on seven-years of phenological observations we provide the first long-term description of leafing patterns of a woody cerrado community, aiming to investigate: (1) the leaf exchange strategies considering the inter-annual variation on the degree of deciduousness of individuals and species and quantify the community deciduousness; (2) the relationship between inter-annual patterns of...
