Diving as a lifestyle has evolved on multiple occasions when air-breathing terrestrial animals invaded the aquatic realm, and diving performance shapes the ecology and behaviour of all air-breathing aquatic taxa, from small insects to great whales. Using the largest dataset yet assembled, we show that maximum dive duration increases predictably with body mass in both ectotherms and endotherms. Compared to endotherms, ectotherms can remain submerged for longer, but the mass scaling relationship for dive duration...
Data from: The relative importance of green infrastructure as refuge habitat for pollinators increases with local land-use intensityPengyao Li, David Kleijn, Isabelle Badenhausser, Carlos Zaragoza-Trello, Nicolas Gross, Ivo Raemakers & Jeroen Scheper
1. Agricultural expansion and intensification have resulted in strong declines in farmland biodiversity across Europe. In many intensively farmed landscapes, linear landscape elements such as field boundaries, road verges and ditch banks are the main remaining green infrastructures providing refuge for biodiversity, and as such play a pivotal role in agri-environmental policies aiming at mitigating biodiversity loss. Yet, while we have a fairly good understanding of how agricultural intensification influences biodiversity on farmland, little is...
Habitat filtering differentially modulates phylogenetic and functional diversity relationships between predatory arthropodsAurélien Ridel, Denis Lafage, Pierre Devogel, Thomas Lacoue-Labarthe & Julien Pétillon
Mechanisms underlying biological diversities at different scales have received significant attention over the last decades. The hypothesis whether local abiotic factors, driving functional and phylogenetic diversities, can differ among taxa of arthropods remains under-investigated. In this study, we compared correlations and drivers of functional (FD) and phylogenetic (PD) diversities between spiders and carabids, two dominant taxa of ground-dwelling arthropods in salt marshes. Both taxa exhibited high correlation between FD and PD; the correlation was even...
Data from: Mercury exposure in an endangered seabird: long-term changes and relationships with trophic ecology and breeding successWilliam Mills, Paco Bustamante, Rona McGill, Orea Anderson, Stuart Bearhop, Yves Cherel, Stephen Votier & Richard Phillips
Mercury (Hg) is an environmental contaminant which, at high concentrations, can negatively influence avian physiology and demography. Albatrosses (Diomedeidae) have higher Hg burdens than all other avian families. Here, we measure total Hg (THg) concentrations of body feathers from adult grey-headed albatrosses (Thalassarche chrysostoma) at South Georgia. Specifically, we: (i) analyse temporal trends at South Georgia (1989–2013) and make comparisons with other breeding populations; (ii) identify factors driving variation in THg concentrations; and, (iii) examine...
Agricultural intensification reduces plant taxonomic and functional diversity across European arable systems.Carlos P Carmona, Irene Guerrero, Begoña Peco, Manuel B. Morales, Juan J Onate, Tomas Pärt, Teja Tscharntke, Jaan Liira, Tsipe Aavik, Mark Emmerson, Frank Berendse, Piotr Ceryngier, Vincent Bretagnolle, Wolfgang Weisser & Jan Bengtsson
1. Agricultural intensification is one of the main drivers of species loss worldwide, but there is still a lack of information about its effect on functional diversity of arable weeds communities. 2. Using a large scale pan European study including 786 fields within 261 farms from eight countries, we analysed differences in the taxonomic and functional diversity of arable weeds assemblages across different levels of agricultural intensification in. We estimated weed species frequency in each...
