Ben M. Sadd, Seth M. Barribeau, Guy Bloch, Dirk C. De Graaf, Peter Dearden, Christine Elsik, Jurgen Gadau, Cornelius Grimmelikhuijzen, Martin Hasselmann, Jeffrey Lozier, Hugh Robertson, Guy Smagghe, Eckart Stolle, Matthias Van Vaerenbergh, Robert Waterhouse, Erich Bornberg-Bauer, Steffan Klasberg, Anna Bennett, Francisco Camara, Roderic Guigo, Katharina Hoff, Marco Mariotti, Monica Munos-Torres, Terence Murphy, Didac Santesmasses … & Kim C. Worley
Background: The shift from solitary to social behavior is one of the major evolutionary transitions. Primitively eusocial bumblebees are uniquely placed to illuminate the evolution of highly eusocial insect societies. Bumblebees are also invaluable natural and agricultural pollinators, and there is widespread concern over recent population declines in some species. High-quality genomic data will inform key aspects of bumblebee biology, including susceptibility to implicated population viability threats. Results: We report the high quality draft genome...

Data from: Metabarcoding of freshwater invertebrates to detect the effects of a pesticide spill

Carmelo Andujar, Paula Arribas, Clare Gray, Katherine Bruce, Guy Woodward, Douglas W. Yu & Alfried P. Vogler
Biomonitoring underpins the environmental assessment of freshwater ecosystems and guides management and conservation. Current methodology for surveys of (macro)invertebrates uses coarse taxonomic identification where species-level resolution is difficult to obtain. Next-generation sequencing of entire assemblages (metabarcoding) provides a new approach for species detection, but requires further validation. We used metabarcoding of invertebrate assemblages with two fragments of the cox1 "barcode" and partial nuclear ribosomal (SSU) genes, to assess the effects of a pesticide spill in...

Data from: Widespread forest vertebrate extinctions induced by a mega hydroelectric dam in lowland Amazonia

Maíra Benchimol & Carlos A. Peres
Mega hydropower projects in tropical forests pose a major emergent threat to terrestrial and freshwater biodiversity worldwide. Despite the unprecedented number of existing, under-construction and planned hydroelectric dams in lowland tropical forests, long-term effects on biodiversity have yet to be evaluated. We examine how medium and large-bodied assemblages of terrestrial and arboreal vertebrates (including 35 mammal, bird and tortoise species) responded to the drastic 26-year post-isolation history of archipelagic alteration in landscape structure and habitat...

Data from: A genomic island linked to ecotype divergence in Atlantic cod

Jakob Hemmer-Hansen, Einar E. Nielsen, Nina O. Therkildsen, Martin I. Taylor, Rob Ogden, Audrey J. Geffen, Dorte Bekkevold, Sarah Helyar, Christophe Pampoulie, Torild Johansen & Gary R. Carvalho
The genomic architecture underlying ecological divergence and ecological speciation with gene flow is still largely unknown for most organisms. One central question is whether divergence is genome-wide or localized in “genomic mosaics” during early stages when gene flow is still pronounced. Empirical work has so far been limited, and the relative impacts of gene flow and natural selection on genomic patterns have not been fully explored. Here, we use ecotypes of Atlantic cod to investigate...

Data from: Habitat use of the ocelot (Leopardus pardalis) in Brazilian Amazon

Bingxin Wang, Daniel G. Rocha, Mark I. Abrahams, André P. Antunes, Hugo C. M. Costa, André Luis Sousa Gonçalves, Wilson Roberto Spironello, Milton José De Paula, Carlos A. Peres, Juarez Pezzuti, Emiliano Ramalho, Marcelo Lima Reis, , Fabio Rohe, David W. Macdonald & Cedric Kai Wei Tan
Amazonia forest plays a major role in providing ecosystem services for human and sanctuaries for wildlife. However, ongoing deforestation and habitat fragmentation in the Brazilian Amazon has threatened both. The ocelot is an ecologically important mesopredator and a potential conservation ambassador species, yet there are no previous studies on its habitat preference and spatial patterns in this biome. From 2010 to 2017, twelve sites were surveyed, totaling 899 camera trap stations, the largest known dataset...

Data from: Paternal personality and social status influence offspring activity in zebrafish

Susanne Zajitschek, James E. Herbert-Read, Nasir M. Abbasi, Felix Zajitschek & Simone Immler
Background: Evidence for the transmission of non-genetic information from father to offspring is rapidly accumulating. While the impact of chemical and physical factors such as toxins or diet on the fitness of the parents and their offspring have been studied extensively, the importance of behavioural and social circumstances has only recently been recognised. Behavioural traits such as personality characteristics can be relatively stable, and partly comprise a genetic component but we know little about the...

Data from: Adaptive thermal plasticity enhances sperm and egg performance in a model insect

Ramakrishnan Vasudeva, Andreas Sutter, Kris Sales, Matthew E. Dickinson, Alyson J. Lumley & Matthew J.G. Gage
Rising and more variable global temperatures pose a challenge for biodiversity, with reproduction and fertility being especially sensitive to heat. Here, we assessed the potential for thermal adaptation in sperm and egg function using Tribolium flour beetles, a warm-temperate-tropical insect model. Following temperature increases through adult development, we found opposing gamete responses, with males producing shorter sperm and females laying larger eggs. Importantly, this gamete phenotypic plasticity was adaptive: thermal translocation experiments showed that both...

Experimental evidence that novel land management interventions inspired by history enhance biodiversity

Robert Hawkes, Jennifer Smart, Andy Brown, Helen Jones, Steve Lane, Colin Lucas, James McGill, Nick Owens, Amanda Ratier Backes, Jonathan Webb, Doreen Wells & Paul Dolman
To address biodiversity declines within semi-natural habitats, land-management must cater for diverse taxonomic groups. Integrating our understanding of the ecological requirements of priority (rare, scarce or threatened) species through ‘biodiversity auditing’, with that of the intensity and complexity of historical land-use, encourages novel forms of management. Experimental confirmation is needed to establish whether this enhances biodiversity conservation relative to routine management. Biodiversity auditing and historical land-use of dry-open terrestrial habitats in Breckland (Eastern England) both...

Phytplanction Juruá River

Joao Vitor Campos-Silva & Carlos Peres
1. Tropical floodplains secure the protein supply of millions of people, but only sound management can ensure the long-term continuity of such ecosystem services. Overfishing is a widespread threat to multitrophic systems, but how it affects ecosystem functioning is poorly understood, particularly in tropical freshwater foodwebs. Models based on temperate lakes frequently assume that primary producers are mostly bottom-up controlled by nutrient and light limitations, with negligible effects of top-down forces. Yet this assumption remains...

Raw data for: Plastic male mating behaviour evolves in response to the competitive environment

Tracey Chapman
Male reproductive phenotypes can evolve in response to the social and sexual environment. The expression of many such phenotypes may also be plastic within an individual’s lifetime. For example, male Drosophila melanogaster show significantly extended mating duration following a period of exposure to conspecific male rivals. The costs and benefits of reproductive investment, and plasticity itself, can be shaped by the prevailing socio-sexual environment and by resource availability. We investigated these ideas using experimental evolution...

Parasite counts for Corydoras maculifer and Corydoras araguaiaensis

Ellen Bell & Martin Taylor
The evolutionary impacts of whole genome duplication events are still unclear. We collected parasite count data and immune gene molecular data for Toll like receptor (TLR) 1 and TLR2 in two catfish species; Corydoras maculifer (diploid) and Corydoras araguaiaensis (putative allotetraploid). Our aim was to compare parasite load and immune gene diversity between these two species.

Individual variation in migratory behavior in a sub-arctic partial migrant shorebird

Verónica Méndez Aragón, Jose Alves, Bodvar Þórisson, Alina Marca, Tomas Gunnarsson & Jennifer Gill
Migratory behavior can differ markedly amongst individuals within populations or species. Understanding the factors influencing this variation is key to understanding how current environmental changes might influence migratory propensity and the distribution and abundance of migratory species across their range. Here, we investigate variation in migratory behavior of the partially migratory Eurasian oystercatcher (Haematopus ostralegus) population breeding in Iceland. We use resightings of color-ringed adults and stable isotopes to determine whether individuals migrate or remain...
