Seawater contains a wealth of genetic information, representing the biodiversity of numerous species residing within a particular marine habitat. Environmental DNA (eDNA) metabarcoding offers a cost effective, non-destructive method for large scale monitoring of environments, as diverse taxonomic groups are detected using metabarcoding assays. A large-scale eDNA monitoring program of marine vertebrates was conducted across three sampling seasons (Spring 2018, Autumn 2019 and Spring 2019) in coastal waters of Brazil. The program was designed to...

Data from: Ontogeny and evolution of the elasmosaurid neck highlight a greater diversity of Antarctic plesiosaurians

Arthur S. Brum, Tiago R. Simões, Geovane A. Souza, André E. P. Pinheiro, Rodrigo G. Figueiredo, Michael W. Caldwell, Juliana M. Sayão & Alexander W. A. Kellner
The Antarctic plesiosaurian record is critical for understanding the evolution of elasmosaurids in the southern hemisphere. Elasmosaurids exhibit some of the most remarkable modifications of the vertebrate axial skeleton given their extreme elongation of the cervical region. Despite a considerable amount of information available on vertebral counts within Plesiosauria throughout the decades, we have a considerably more limited understanding of the diversity of cervical vertebral shapes in elasmosaurids and how these have changed throughout ontogeny...

Brock Bastian, Christin-Melanie Vauclair, Steve Loughnan, Paul Bain, Ashwini Ashokkumar, Maja Becker, Michal Bilewicz, Emma Collier-Baker, Carla Crespo, Paul W. Eastwick, Ronald Fischer, Malte Friese, Ángel Gómez, Valeschka M. Guerra, Jose Luis Castellanos Guevara, Katja Hanke, Nic Hooper, Li-Li Huang, Shi Junqi, Minoru Karasawa, Peter Kuppens, Siri Leknes, Müjde Peker, Cesar Pelay, Afoditi Pina … & William B. Swann
Pathogens represent a significant threat to human health leading to the emergence of strategies designed to help manage their negative impact. We examined how spiritual beliefs developed to explain and predict the devastating effects of pathogens and spread of infectious disease. Analysis of existing data in Studies 1 and 2 suggests that moral vitalism (beliefs about spiritual forces of evil) is higher in geographical regions characterized by historical higher levels of pathogens. Furthermore, drawing on...

Similar but different: Revealing the relative roles of species‐traits versus biome properties structuring genetic variation in South American marsh rats

Joyce Rodrigues Do Prado, Joyce R. Prado, Alexandre R. Percequillo, Andréa T. Thomaz & L. Lacey Knowles
Aim: Wetland habitats, and the ecological restrictions imposed by them, structure patterns of genetic variation in constituent taxa. As such, genetic variation may reflect properties of the specific biomes species inhabit, or shared life history traits among species may result in similar genetic structure. We evaluated these hypotheses jointly by quantifying the similarity of genetic structure in three South American marsh rat species (Holochilus), and test how genetic variation in each species relates to biome‐specific...

Aim: As a step towards providing support for an ecological approach to strengthening marine protected areas (MPAs) and meeting international commitments, this study combines cumulative impact assessment and conservation planning approach to undertake a large-scale spatial prioritisation. Location: Exclusive Economic Zone (EEZ) of Brazil, Southwest Atlantic Ocean Methods: We developed a prioritisation approach to protecting different habitat types, threatened species ranges, and ecological connectivity, while also mitigating the impacts of multiple threats on biodiversity. When...

Tempo and mode of evolution of Oryzomyine rodents (Rodentia, Cricetidae, Sigmodontinae): a phylogenomic approach

Alexandre Percequillo, Joyce Prado, Edson Abreu, Jeronymo Dalapicolla, Ana Carolina Pavan, Elisandra Chiquito, Pamella Brennand, Scott Steppan, Alan Lemmon & Emily Lemmon
The tribe Oryzomyini is an impressive group of rodents, comprising 30 extant genera and an estimated 147 species. Recent remarkable advances in the understanding of the diversity, taxonomy and systematics of the tribe have mostly derived from analyses of single or few genetic markers. However, the evolutionary history and biogeography of Oryzomyini, its origin and diversification across the Neotropics, remain unrevealed. Here we use a multi-locus dataset (over 400 loci) obtained through anchored phylogenomics to...

Data from: Independent reversals to terrestriality in squirrels (Rodentia: Sciuridae) support ecologically mediated modes of adaptation

R.G. Rocha, Yuri L.R. Leite, Leonora P. Costa & Danny Rojas
The family Sciuridae is one of the most widespread and ecologically diverse lineage of rodents and represents an ideal model for investigating the evolution of locomotion modes and the historical biogeography of terrestrial mammals. We used a comprehensive database on locomotion modes, an updated phylogeny and novel biogeographic comparative methods to re-assess the evolution of locomotion of squirrels and to investigate if these locomotion modes evolved convergently in different continents. We found that locomotion changes...

Highways are a threat for giant armadillos (Priodontes maximus) that underpasses can mitigate

Aureo Banhos, Bruno Fontes, Debora Yogui, Mario Henrique Alves, Natália Carneiro Ardente, Renata Valls, Lucas Mendes Barreto, Lucas Damásio, Átilla Colombo Ferreguetti, Andréa Siqueira Carvalho, Vitor Roberto Schettino, Alexandre Rosa Dos Santos, Helena Godoy Bergallo, Ana Carolina Srbek-Araujo, Patricia Medici, Ariel Canena & Arnaud Desbiez
We report 22 records of giant armadillo roadkill on Brazilian highways in the Cerrado, Pantanal and Amazon biomes illustrating that highways are a threat to this species. However, we also documented the species using underpasses, demonstrating that these structures could help to reduce the risk of roadkill for giant armadillos.

Data from: Atlantic Forest topsoil nutrients can be resistant to disturbance and forest clearing

Nathália Vieira Hissa Safar, Luiz Fernando Silva Magnago, Samir Gonçalves Rolim & Carlos Ernesto Gonçalves Reynauld Schaefer.
Human impacts can affect soil properties through erosion and leaching when vegetation is removed, the ecosystem functions and, consequently, the capacity of a forest to regenerate. Here, we determine the effects of forest disturbance and succession on selected soil chemical properties using two different approaches, before-after control-impact (BACI) and space-for-time (SFT) substitution, and the threatened Atlantic Forest biome as model. We assessed with BACI the long-term (37-yr) effects of clear-cutting on soil properties by comparing...

Data from: Seasonal dynamics of megafauna on the deep West Antarctic Peninsula shelf in response to variable phytodetrital influx

Paulo Y. G. Sumida, Craig R. Smith, Angelo F. Bernardino, Paulo S. Polito & Danilo R. Vieira
The deep West Antarctic Peninsula (WAP) shelf is characterized by intense deposition of phytodetritus during spring/summer months, while very little food material reaches the seafloor during winter. The response of the shelf benthic megafauna to this highly variable food supply is still poorly understood. In order to characterize the deposition of phytodetritus and the megabenthic community response, we deployed a seafloor time-lapse camera at approximately 590 m depth on the mid WAP shelf west of...

Data from: Dynamics of coral reef benthic assemblages of the Abrolhos Bank, eastern Brazil: inferences on natural and anthropogenic drivers

Ronaldo B. Francini-Filho, Ericka O. C. Coni, Pedro M. Meirelles, Gilberto M. Amado-Filho, Fabiano L. Thompson, Guilherme H. Pereira-Filho, Alex C. Bastos, Douglas P. Abrantes, Camilo M. Ferreira, Fernando Z. Gibran, Arthur Z. Güth, Paulo Y. G. Sumida, Nara L. Oliveira, Les Kaufman, Carolina V. Minte-Vera & Rodrigo L. Moura
The Abrolhos Bank (eastern Brazil) encompasses the largest and richest coral reefs of the South Atlantic. Coral reef benthic assemblages of the region were monitored from 2003 to 2008. Two habitats (pinnacles’ tops and walls) were sampled per site with 3-10 sites sampled within different reef areas. Different methodologies were applied in two distinct sampling periods: 2003-2005 and 2006-2008. Spatial coverage and taxonomic resolution were lower in the former than in the latter period. Benthic...

Data from: Species Delimitation of Endemic Atlantic Forest Inga subnuda (Leguminosae, Caesalpinioideae, mimosoid clade) Subspecies Based on Morphological, Ecological and Palaeoecological Data

Michael Aejandro Castro-Bonilla, Pedro S. R. Romano, Marcelo Bueno, Valquíria Dutra, Jeferson Fregonezi & Flavia Garcia
Inga subnuda Salzm. ex Benth. are one of 31 endemic species in the Brazilian Atlantic Forest. Intermixed leaf and floral traits have made morphological distinctiveness difficult, and its current taxonomic treatment considers I. subnuda as one species with two subspecies. We aim to explore different lines of evidence to disentangle and clarify species boundaries in these two subspecies. Morphological variation and bioclimatic data of the two subspecies of the complex were assessed by using multivariate...

Data from: The anti-predator role of within-nest emergence synchrony in sea turtle hatchlings

Robson G. Santos, Hudson Tercio Pinheiro, Agnaldo Silva Martins, Pablo Riul, Soraya Christina Bruno, Fredric J. Janzen & Christos C. Ioannou
Group formation is a common behaviour among prey species. In egg-laying animals, despite the various factors that promote intra-clutch variation leading to asynchronous hatching and emergence from nests, synchronous hatching and emergence occurs in many taxa. This synchrony may be adaptive by reducing predation risk, but few data are available in any natural system, even for iconic examples of the anti-predator function of group formation. Here, we show for the first time that increased group...
