Data from: The effect of close relatives on unsupervised Bayesian clustering algorithms in population genetic structure analysis

Silvia T. Rodríguez-Ramilo & Jinliang Wang
The inference of population genetic structures is essential in many research areas in population genetics, conservation biology and evolutionary biology. Recently, unsupervised Bayesian clustering algorithms have been developed to detect a hidden population structure from genotypic data, assuming among others that individuals taken from the population are unrelated. Because of this hypothesis, markers in a sample taken from a subpopulation can be considered to be in Hardy-Weinberg and linkage equilibrium. However, close relatives might be...

Data from: Phenotypic and genetic divergence among harbour porpoise populations associated with habitat regions in the North Sea and adjacent seas.

Carlos De Luna Lopez, Simon J. Goodman, Oliver Thatcher, Paul D. Jepson, Liselotte Andersen, Krystal Tolley & Alan R. Hoelzel
Determining the mechanisms that generate population structure is essential to the understanding of speciation and the evolution of biodiversity. Here, we investigate a geographic range that transects two habitat gradients, the North Sea to North Atlantic transition, and the temperate to sub-polar regions. We studied the harbour porpoise (Phocoena phocoena), a small odontocete inhabiting both sub-polar and temperate waters. To assess differentiation among putative populations we measured morphological variation at cranial traits (N=462 individuals) and...

Data from: Genetic erosion in wild populations makes resistance to a pathogen more costly

Emilien Luquet, Trenton W. J. Garner, Jean-Paul Léna, Christophe Bruel, Pierre Joly, Thierry Lengagne, Odile Grolet & Sandrine Plénet
Populations that have suffered from genetic erosion are expected to exhibit reduced average trait values or decreased variation in adaptive traits when experiencing periodic or emergent stressors such as infectious disease. Genetic erosion may consequentially modify the ability of a potential host population to cope with infectious disease emergence. We experimentally investigate this relationship between genetic variability and host response to exposure to an infectious agent both in terms of susceptibility to infection and indirect...

Data from: Recent northward range expansion promotes song evolution in a passerine bird, the Light-vented Bulbul

Xiaoying Xing, Per Alström, Xiaojing Yang, Fumin Lei, F. M. Lei & X. J. Yang
In common with human speech, song is culturally inherited in oscine passerine birds (‘songbirds’). Intraspecific divergence in birdsong, such as development of local dialects, might be an important early step in the speciation process. It is therefore vital to understand how songs diverge, especially in founding populations. The northward expansion of the Light-vented Bulbul Pycnonotus sinensis (J. F. Gmelin, 1789) into north China in the last 30 years provides an excellent opportunity to study birdsong...

Data from: Impact of climate changes from Middle Miocene onwards on evolutionary diversification in Eurasia: insights from the mesobuthid scorpions

Cheng-Min Shi, Ya-Jie Ji, Lin Liu, Lei Wang & De-Xing Zhang
The aridification from Middle Miocene onwards has transformed the Asian interior into an arid environment, and the Pleistocene glacial–interglacial oscillations exerted further ecological impact. Therefore, both aridification and glaciation would have considerably influenced the evolution of many mid-latitude species in temperate Asia. Here, we tested this perspective by a phylogeographic study of the mesobuthid scorpions across temperate Asia using one mitochondrial and three nuclear genes. Concordant mitochondrial and nuclear gene trees were obtained, which are...

Data from: Does catch and release affect the mating system and individual reproductive success of wild Atlantic salmon (Salmo salar L.)?

Antoine Richard, Mélanie Dionne, Jinliang Wang & Louis Bernatchez
In this study, we documented the breeding system of a wild population of Atlantic salmon (Salmo salar L.) by genetically sampling every returning adult and assessed the determinants of individual fitness. We then quantified the impacts of catch and release (C&R) on mating and reproductive success. Both sexes showed high variance in individual reproductive success, and the estimated standardized variance was higher for males (2.86) than for females (0.73). We found a weak positive relationship...

Data from: Inbreeding and inbreeding depression of early life traits in a cooperative mammal

Johanna F. Nielsen, Sinead English, William P. Goodall-Copestake, Jinliang Wang, Craig A. Walling, Andrew W. Bateman, Loeske E. B. Kruuk, Tim H. Clutton-Brock & Josephine M. Pemberton
Mating between relatives often results in negative fitness consequences or inbreeding depression. However, the expression of inbreeding in populations of wild cooperative mammals and the effects of environmental, maternal and social factors on inbreeding depression in these systems are currently not well understood. This study uses pedigree-based inbreeding coefficients from a long-term study of meerkats (Suricata suricatta) in South Africa to reveal that 44% of the population have detectably non-zero (F>0) inbreeding coefficients. 15% of...

Data from: Reproductive conflict in bumblebees and the evolution of worker policing

Lorenzo Roberto Sgobaro Zanette, Sophie D. L. Miller, Christiana M. A. Faria, Edd J. Almond, Tim J. Huggins, William C. Jordan & Andrew F. G. Bourke
Worker policing (mutual repression of reproduction) in the eusocial Hymenoptera represents a leading example of how coercion can facilitate cooperation. The occurrence of worker policing in “primitively” eusocial species with low mating frequencies, which lack relatedness differences conducive to policing, suggests that separate factors may underlie the origin and maintenance of worker policing. We tested this hypothesis by investigating conflict over male parentage in the primitively eusocial, monandrous bumblebee, Bombus terrestris. Using observations, experiments, and...
