Data from: Foraging bumblebees use social cues more when the task is difficult

David Baracchi, Vera Vasas, Soha Jamshed Iqbal & Sylvain Alem
When foraging in their natural environment, many animals readily complement their personal knowledge with additional social information. To balance the costs and benefits of copying others, animals have to discern situations in which it is more advantageous to use social rather than personal information. Here, we used foraging bumblebees (Bombus terrestris) in a controlled laboratory setting and showed that the difficulty of a foraging task affects how the bees weight the two types of information....

Data from: Contrasting trajectories of morphological diversification on continents and islands in the Afrotropical white-eye radiation

Julia J. Day, Frederico C. Martins, Joseph A. Tobias & David J. Murrell
Aim Morphological and lineage evolution are predicted to follow different patterns in island and mainland radiations. However, the extent to which these geographical contexts influence evolutionary trajectories remains poorly understood, in part because few studies have focused on species-rich clades colonising continents and archipelagos over comparable timeframes. Focusing on a diverse songbird clade radiating on the African continent and adjacent islands, we tested whether morphological evolution is best explained by adaptive or non-adaptive processes, and...

Full-likelihood analysis of genomic data clarifies a complex history of species divergence and introgression in the erato-sara group of Heliconius butterflies

Yuttapong Thawornwattana, Fernando Seixas, Ziheng Yang & James Mallet
Introgression plays a key role in adaptive evolution and species diversification in many groups of species including Heliconius butterflies. However, frequent hybridization and gene flow between species makes estimation of the species phylogeny challenging, especially for rapidly speciating species within adaptive radiations. Here, we analyze the genomic sequences from six members of the erato-sara clade of Heliconius butterflies to infer the species phylogeny and cross-species introgression events. To avoid heterozygote phasing errors in haploid sequences...

Data and R-code from Hubau W et al. 2020. 'Asynchronous Saturation of the Carbon Sink in African and Amazonian tropical forests'. Nature 579, 80-87. 2020. DOI: 10.1038/s41586-020-2035-0. ABSTRACT: Structurally intact tropical forests sequestered ~50% of global terrestrial carbon uptake over the 1990s and early 2000s, offsetting ~15% of anthropogenic CO2 emissions1-3. Climate-driven vegetation models typically predict that this tropical forest ‘carbon sink’ will continue for decades4,5. However, recent inventories of intact Amazonian forests show declining...

Data from: Spatiotemporal variation in completeness of the early cynodont fossil record and its implications for mammalian evolutionary history

Grace Varnham, Philip Mannion & Christian Kammerer
Mammals are the only surviving group of Cynodontia, a synapsid clade that first appears in the fossil record in the late Permian, ~260 million years ago. Here, using three metrics that capture skeletal completeness, we quantify the quality of the early cynodont fossil record in time and space to evaluate the impact of sampling and preservational biases on our understanding of the group’s evolutionary history. There is no consistent global sampling signal for early cynodonts....

Data from: An overrepresentation of high frequencies in the mouse inferior colliculus supports the processing of ultrasonic vocalizations

Jose A. Garcia-Lazaro, Kathryn N. Shepard, Jason A. Miranda, Robert C. Liu & Nicholas A. Lesica
Mice are of paramount importance in biomedical research and their vocalizations are a subject of interest for researchers across a wide range of health-related disciplines due to their increasingly important value as a phenotyping tool in models of neural, speech and language disorders. However, the mechanisms underlying the auditory processing of vocalizations in mice are not well understood. The mouse audiogram shows a peak in sensitivity at frequencies between 15-25 kHz, but weaker sensitivity for...

Data from: Anthropogenic and ecological drivers of amphibian disease (Ranavirosis)

Alexandra C. North, David J. Hodgson, Stephen J. Price & Amber G. F. Griffiths
Ranaviruses are causing mass amphibian die-offs in North America, Europe and Asia, and have been implicated in the decline of common frog (Rana temporaria) populations in the UK. Despite this, we have very little understanding of the environmental drivers of disease occurrence and prevalence. Using a long term (1992-2000) dataset of public reports of amphibian mortalities, we assess a set of potential predictors of the occurrence and prevalence of Ranavirus-consistent common frog mortality events in...

Data from: Paleo-islands as refugia and sources of genetic diversity within volcanic archipelagos: The case of the widespread endemic Canarina canariensis (Campanulaceae)

Mario Mairal, Isabel Sanmartín, Juan José Aldasoro, Victoria Culshaw, Ioanna Manolopoulou & Marisa Alarcón
Geographical isolation by oceanic barriers and climatic stability has been postulated as some of the main factors driving diversification within volcanic archipelagos. However, few studies have focused on the effect that catastrophic volcanic events have had on patterns of within-island differentiation in geological time. This study employed data from the chloroplast (cpDNA haplotypes) and the nuclear (AFLPs) genomes to examine the patterns of genetic variation in Canarina canariensis, an iconic plant species associated with the...

Data from: Phylogenetic community ecology of soil biodiversity using mitochondrial metagenomics

Carmelo Andújar, Paula Arribas, Filip Ruzicka, Alexandra Crampton Platt, Martijn J. T. N. Timmermans, Alfried P. Vogler & Alex Crampton-Platt
High-throughput DNA methods hold great promise for the study of taxonomically intractable mesofauna of the soil. Here, we assess species diversity and community structure in a phylogenetic framework, by sequencing total DNA from bulk specimen samples and assembly of mitochondrial genomes. The combination of mitochondrial metagenomics and DNA barcode sequencing of 1494 specimens in 69 soil samples from three geographic regions in southern Iberia revealed >300 species of soil Coleoptera (beetles) from a broad spectrum...

Data from: Chromosome-level assembly reveals extensive rearrangement in saker falcon and budgerigar, but not ostrich, genomes

Rebecca E. O'Connor, Marta Farre, Sunitha Jospeh, Joana Damas, Lucas Kiazim, Rebecca Jennings, Sophie Bennett, Eden A. Slack, Emily Allanson, Denis M. Larkin & Darren K. Griffin
The number of de novo genome sequence assemblies is increasing exponentially; however, relatively few contain one scaffold/contig per chromosome. Such assemblies are essential for studies of genotype-to-phenotype association, gross genomic evolution, and speciation. Inter-species differences can arise from chromosomal changes fixed during evolution, and we previously hypothesized that a higher fraction of elements under negative selection contributed to avian-specific phenotypes and avian genome organization stability. The objective of this study is to generate chromosome-level assemblies...

Data from: Community water improvement, household water insecurity, and women’s psychological distress: an intervention and control study in Ethiopia

Edward G. J. Stevenson, Argaw Ambelu, Bethany A. Caruso, Yihenew Tesfaye & Matthew C. Freeman
Background: Over 650 million people worldwide lack access to safe water supplies, and even among those who have gained access to ‘improved’ sources, water may be seasonally unreliable, far from homes, expensive, and provide insufficient quantity. Measurement of water access at the level of communities and households remains crude, and better measures of household water insecurity are urgently needed to inform needs assessments and monitoring and evaluation. We set out to assess the validity of...

Data from: Terrestrial mammalian wildlife responses to Unmanned Aerial Systems approaches

Emily Bennitt, Hattie L.A. Bartlam-Brooks, Tatjana Y. Hubel & Alan M. Wilson
Unmanned Aerial Systems (UAS) are increasingly being used recreationally, commercially and for wildlife research, but very few studies have quantified terrestrial mammalian reactions to UAS approaches. We used two Vertical Take-off and Landing (VTOL) UAS to approach seven herbivore species in the Moremi Game Reserve, Botswana, after securing the relevant permissions. We recorded responses to 103 vertical and 120 horizontal approaches, the latter from three altitudes above ground level (AGL). We ran mixed logistic regressions...
