Data from: Maternal, social and abiotic environment effects on growth vary across life stages in a cooperative mammal

Sinead English, Andrew W. Bateman, Rafael Mares, Arpat Ozgul & Tim H. Clutton-Brock
1. Resource availability plays a key role in driving variation in somatic growth and body condition, and the factors determining access to resources vary considerably across life stages. Parents and carers may exert important influences in early life, when individuals are nutritionally dependent, with abiotic environmental effects having stronger influences later in development as individuals forage independently. 2. Most studies have measured specific factors influencing growth across development, or have compared relative influences of different...

Data from: Ion Torrent PGM as tool for fungal community analysis: a case study of endophytes in Eucalyptus grandis reveals high taxonomic diversity

Martin Kemler, Jeff Garnas, Michael J. Wingfield, Marieka Gryzenhout, Kerry-Anne Pillay & Bernard Slippers
The Kingdom Fungi adds substantially to the diversity of life, but due to their cryptic morphology and lifestyle, tremendous diversity, paucity of formally described specimens, and the difficulty in isolating environmental strains into culture, fungal communities are difficult to characterize. This is especially true for endophytic communities of fungi living in healthy plant tissue. The developments in next generation sequencing technologies are, however, starting to reveal the true extent of fungal diversity. One of the...

Data from: Facial attractiveness is related to women’s cortisol and body fat, but not with immune responsiveness

Markus J. Rantala, Vinet Coetzee, Fhionna R. Moore, Ilona Skrida, Sanita Kecko, Tatjana Krama, Inese Kivleniece, Indrikis Krams & I. Skrinda
Recent studies suggest that facial attractiveness indicates immune responsiveness in men and that this relationship is moderated by stress hormones which interact with testosterone levels. However, studies testing whether facial attractiveness in women signals their immune responsiveness are lacking. Here, we photographed young Latvian women, vaccinated them against hepatitis B and measured the amount of specific antibodies produced, cortisol levels and percentage body fat. Latvian men rated the attractiveness of the women's faces. Interestingly, in...

Data from: Long-distance dispersal maximizes evolutionary potential during rapid geographic range expansion

Cécile Berthouly-Salazar, Cang Hui, Tim M. Blackburn, Coline Gaboriaud, Berndt J. Van Rensburg, Bettine Jansen Van Vuuren & Johannes J. Le Roux
Conventional wisdom predicts that sequential founder events will cause genetic diversity to erode in species with expanding geographic ranges, limiting evolutionary potential at the range margin. Here, we show that invasive European starlings (Sturnus vulgaris) in South Africa preserve genetic diversity during range expansion, possibly as a result of frequent long-distance dispersal events. We further show that unfavourable environmental conditions trigger enhanced dispersal, as indicated by signatures of selection detected across the expanding range. This...
