Data from: Identifying conservation priorities for gorgonian forests in Italian coastal waters with multiple methods including citizen science and social media content analysis

Arianna Liconti
Gorgonian forests are among the most complex of subtidal habitats in the Mediterranean Sea, supporting high biodiversity and providing diverse ecosystem services. Despite their iconic status, the geographical distribution and condition of gorgonian species is poorly known. Using multiple online data sources, our primary aims were to compile, map and analyse observations of gorgonian forests in Italian coastal waters to assess the biological complexity of gorgonian forests; evaluate impacts and vulnerable species, and identify areas...

Optimal searching behaviour generated intrinsically by the central pattern generator for locomotion

Jimena Berni, David W. Sims & Nicolas E. Humphries
Efficient searching for resources such as food by animals is key to their survival. It has been proposed that diverse animals from insects to sharks and humans adopt searching patterns that resemble a simple Lévy random walk, which is theoretically optimal for ‘blind foragers’ to locate sparse, patchy resources. To test if such patterns are generated intrinsically, or arise via environmental interactions, we tracked free-moving Drosophila larvae with (and without) blocked synaptic activity in the...

Data from: Global honey bee viral landscape altered by a parasitic mite

Stephen J. Martin, Andrea C. Highfield, Laura Brettell, Ethel M. Villalobos, Giles E. Budge, Michelle Powell, Scott Nikaido & Declan C. Schroeder
Emerging diseases are among the greatest threats to honey bees. Unfortunately, where and when an emerging disease will appear are almost impossible to predict. The arrival of the parasitic Varroa mite into the Hawaiian honey bee population allowed us to investigate changes in the prevalence, load, and strain diversity of honey bee viruses. The mite increased the prevalence of a single viral species, deformed wing virus (DWV), from ~10 to 100% within honey bee populations,...

Data from: Environmental variation is a major predictor of global trait turnover in mammals

Ben G. Holt, Gabriel C. Costa, Caterina Penone, Jean-Philippe Lessard, Thomas M. Brooks, Ana D. Davidson, S. Blair Hedges, Volker C. Radeloff, Carsten Rahbek, Carlo Rondinini & Catherine H. Graham
Aim: To evaluate how environment and evolutionary history interact to influence global patterns of mammal trait diversity (a combination of 14 morphological and life-history traits). Location: The global terrestrial environment. Taxon: Terrestrial mammals. Methods: We calculated patterns of spatial turnover for mammalian traits and phylogenetic lineages using the mean nearest taxon distance. We then used a variance partitioning approach to establish the relative contribution of trait conservatism, ecological adaptation and clade specific ecological preferences on...

Data from: Long-term, high frequency in situ measurements of intertidal mussel bed temperatures using biomimetic sensors

Brian Helmuth, Francis Choi, Allison Matzelle, Jessica L. Torossian, Scott L. Morella, K. A. S. Mislan, Lauren Yamane, Denise Strickland, P. Lauren Szathmary, Sarah Gilman, Alyson Tockstein, Thomas J. Hilbish, Michael T. Burrows, Anne Marie Power, Elizabeth Gosling, Nova Mieszkowska, Christopher D. G. Harley, Michael Nishizaki, Emily Carrington, Bruce Menge, Laura Petes, Melissa M. Foley, Angela Johnson, Megan Poole, Mae M. Noble … & Gerardo Zardi
At a proximal level, the physiological impacts of global climate change on ectothermic organisms are manifest as changes in body temperatures. Especially for plants and animals exposed to direct solar radiation, body temperatures can be substantially different from air temperatures. We deployed biomimetic sensors that approximate the thermal characteristics of intertidal mussels at 71 sites worldwide, from 1998-present. Loggers recorded temperatures at 10–30 min intervals nearly continuously at multiple intertidal elevations. Comparisons against direct measurements...

Data from: Year-round sexual harassment as a behavioral mediator of vertebrate population dynamics

Victoria Wearmouth, Emily Southall, David Morritt, Richard C. Thompson, Innes C. Cuthill, Julian Partridge, David W. Sims & Julian C. Partridge
Within-species sexual segregation is a widespread phenomenon among vertebrates but its causes remain a topic of much debate. Female avoidance of male coercive mating attempts has the potential to influence the social structure of animal populations, yet it has been largely overlooked as a driver of sexual separation. Indeed, its potential role in long-term structuring of natural populations has not been studied. Here we use a comparative approach to examine the suitability of multiple hypotheses...
