Data from: Rapid human-induced divergence of life-history strategies in Bahamian livebearing fishes (family Poeciliidae)

Rüdiger Riesch, Tara Easter, Craig A. Layman & Randall Brian Langerhans
1. Human-induced rapid environmental change (HIREC) can have dramatic impacts on ecosystems, leading to rapid trait changes in some organisms and extinction in others. Such changes in traits signify that human actions can lead to cases of increased phenotypic diversity and consequently can strongly impact population-, community- and ecosystem-level dynamics. 2. Here, we examine whether the ecological consequences of habitat fragmentation have led to changes in the life histories of three native species of mosquitofish...

Data from: Allometry and growth of eight tree taxa in United Kingdom woodlands

Matthew R. Evans, Aristides Moustakas, Gregory Carey, Yadvinder Malhi, Nathalie Butt, Sue Benham, Denise Pallett & Stefanie Schäfer
As part of a project to develop predictive ecosystem models of United Kingdom woodlands we have collated data from two United Kingdom woodlands - Wytham Woods and Alice Holt. Here we present data from 582 individual trees of eight taxa in the form of summary variables relating to the allometric relationships between trunk diameter, height, crown height, crown radius and trunk radial growth rate to the tree’s light environment and diameter at breast height. In...

Data from: Selection on a genetic polymorphism counteracts ecological speciation in a stick insect

Aaron A. Comeault, Samuel M. Flaxman, Rüdiger Riesch, Emma Curran, Víctor Soria-Carrasco, Zachariah Gompert, Timothy E. Farkas, Moritz Muschick, Thomas L. Parchman, Tanja Schwander, Jon Slate & Patrik Nosil
The interplay between selection and aspects of the genetic architecture of traits (such as linkage, dominance, and epistasis) can either drive or constrain speciation. Despite accumulating evidence that speciation can progress to “intermediate” stages—with populations evolving only partial reproductive isolation—studies describing selective mechanisms that impose constraints on speciation are more rare than those describing drivers. The stick insect Timema cristinae provides an example of a system in which partial reproductive isolation has evolved between populations...

Data from: Having a lot of a good thing: multiple important group memberships as a source of self-esteem

Jolanda Jetten, Nyla R. Branscombe, S. Alexander Haslam, Catherine Haslam, Tegan Cruwys, Janelle M. Jones, Lijuan Cui, Genevieve Dingle, James Liu, Sean Murphy, Anh Thai, Zoe Walter & Airong Zhang
Membership in important social groups can promote a positive identity. We propose and test an identity resource model in which personal self-esteem is boosted by membership in additional important social groups. Belonging to multiple important group memberships predicts personal self-esteem in children (Study 1a), older adults (Study 1b), and former residents of a homeless shelter (Study 1c). Study 2 shows that the effects of multiple important group memberships on personal self-esteem are not reducible to...

Data from: Building a beetle: how larval environment leads to adult performance in a horned beetle

Leeann T. Reaney & Robert J. Knell
The link between the expression of the signals used by male animals in contests with the traits which determine success in those contests is poorly understood. This is particularly true in holometabolous insects such as horned beetles where signal expression is determined during metamorphosis and is fixed during adulthood, whereas performance is influenced by post-eclosion feeding. We used path analysis to investigate the relationships between larval and adult nutrition, horn and body size and fitness-related...

Data from: The role of host phenology in determining the incidence of an insect sexually transmitted infection

Daria Pastok, Mary-Jo Hoare, Jonathan J. Ryder, Michael Boots, Rob J. Knell, David Atkinson, Gregory D. D. Hurst & Mike Boots
Changes in the timing of life history events within the year alter the degree to which the activity patterns of different species coincide, making the dynamics of interspecific interactions sensitive to the phenology of the interacting parties. For parasites, the availability of suitable hosts to infect represents a crucial determinant of dynamics, and changes in the host (and parasite) phenology may thus alter disease epidemiology and the conditions for disease maintenance. We tested the hypothesis...

Data from: Speciation processes in putative island endemic sister bat species: false impressions from mitochondrial DNA and microsatellite data

Hao-Chih Kuo, Shiang-Fan Chen, Yin-Ping Fang, James A. Cotton, Joe D. Parker, Gábor Csorba, Burton K. Lim, Judith L. Eger, Chia-Hong Chen, Cheng-Han Chou & Stephen J. Rossiter
Cases of geographically restricted co-occurring sister taxa are rare and may point to potential divergence with gene flow. The two bat species Murina gracilis and M. recondita are both endemic to Taiwan and are putative sister species. To test for non-allopatric divergence and gene flow in these taxa, we generated sequences using Sanger and Next Generation Sequencing, and combined these with microsatellite data for coalescent-based analyses. MtDNA phylogenies supported the reciprocally monophyletic sister relationship between...

Data from: A phylogenomic analysis of the role and timing of molecular adaptation in the aquatic transition of cetartiodactyl mammals

Georgia Tsagkogeorga, Michael R. McGowen, Kalina T. J. Davies, Simon Jarman, Andrea Polanowski, Mads F. Bertelsen & Stephen J. Rossiter
Recent studies have reported multiple cases of molecular adaptation in cetaceans related to their aquatic abilities. However, none of these has included the hippopotamus, precluding an understanding of whether molecular adaptations in cetaceans occurred before or after they split from their semi-aquatic sister taxa. Here, we obtained new transcriptomes from the hippopotamus and humpback whale, and analysed these together with available data from eight other cetaceans. We identified more than 11 000 orthologous genes and...

Data from: Microform-scale variations in peatland permeability and their ecohydrological implications

Andy J. Baird, Alice M. Milner, Antony Blundell, Graeme T. Swindles & Paul J. Morris
1. The acrotelm-catotelm model of peatland hydrological and biogeochemical processes posits that the permeability of raised bogs is largely homogenous laterally but varies strongly with depth through the soil profile; uppermost peat layers are highly permeable while deeper layers are, effectively, impermeable. 2. We measured down-core changes in peat permeability, plant macrofossil assemblages, dry bulk density and degree of humification beneath two types of characteristic peatland microform – ridges and hollows – at a raised...

Data from: A sting in the spit: widespread cross-infection of multiple RNA viruses across wild and managed bees

Dino P. McMahon, Matthias A. Fürst, Jesicca Caspar, Panagiotis Theodorou, Mark J. F. Brown & Robert J. Paxton
1.Declining populations of bee pollinators are a cause of concern, with major repercussions for biodiversity loss and food security. RNA viruses associated with honeybees represent a potential threat to other insect pollinators, but the extent of this threat is poorly understood. 2.This study aims to attain a detailed understanding of the current and on going risk of emerging infectious disease (EID) transmission between managed and wild pollinator species across a wide range of RNA viruses....

Data from: Epidemiological interactions between urogenital and intestinal human schistosomiasis in the context of praziquantel treatment across three West African countries

Sarah C. L. Knowles, Bonnie L. Webster, Amadou Garba, Moussa Sacko, Oumar T. Diaw, Alan Fenwick, David Rollinson & Joanne P. Webster
Background: In many parts of sub-Saharan Africa, urogenital and intestinal schistosomiasis co-occur, and mixed species infections containing both Schistosoma haematobium and S. mansoni can be common. During co-infection, interactions between these two species are possible, yet the extent to which such interactions influence disease dynamics or the outcome of control efforts remains poorly understood. Methodology/Principal Findings: Here we analyse epidemiological data from three West African countries co-endemic for urogenital and intestinal schistosomiasis (Senegal, Niger and...
