Data from: Nonrandom dispersal drives phenotypic divergence within a bird population

Carlos Camacho, David Canal & Jaime Potti
Gene flow through dispersal has traditionally been thought to function as a force opposing evolutionary differentiation. However, directional gene flow may actually reinforce divergence of populations in close proximity. This study documents the phenotypic differentiation over more than two decades in body size (tarsus length) at a very short spatial scale (1.1 km) within a population of pied flycatchers Ficedula hypoleuca inhabiting deciduous and coniferous habitats. Unlike females, males breeding in the deciduous forest were...

Data from: Parasites affect food web structure primarily through increased diversity and complexity

Jennifer A. Dunne, Kevin D. Lafferty, Andrew P. Dobson, Ryan F. Hechinger, Armand M. Kuris, Neo D. Martinez, John P. McLaughlin, Kim N. Mouritsen, Robert Poulin, Karsten Reise, Daniel B. Stouffer, David W. Thieltges, Richard J. Williams & Claus Dieter Zander
Comparative research on food web structure has revealed generalities in trophic organization, produced simple models, and allowed assessment of robustness to species loss. These studies have mostly focused on free-living species. Recent research has suggested that inclusion of parasites alters structure. We assess whether such changes in network structure result from unique roles and traits of parasites or from changes to diversity and complexity. We analyzed seven highly resolved food webs that include metazoan parasite...

Data from: Temporal dynamics of direct reciprocal and indirect effects in a host-parasite network

Shai Pilosof, Miguel A. Fortuna, Maxim V. Vinarski, Natalia P. Korallo-Vinarskaya & Boris R. Krasnov
1. Temporal variation in the direct and indirect influence that hosts and parasites exert on each other is still poorly understood. However, variation in species’ influence due to species and interactions turnover can have important consequences for host community dynamics and/or for parasite transmission dynamics, and eventually for the risk of zoonotic diseases. 2. We used data on a network of small mammals and their ectoparasites surveyed over six years to test hypotheses exploring (1)...

Data from: Lifetime fitness and age-related female ornament signalling: evidence for survival and fecundity selection in the pied flycatcher

Jaime Potti, David Canal & David Serrano
Ornaments displayed by females have often been denied evolutionary interest due to their frequently reduced expression relative to males, habitually attributed to a genetic correlation between the sexes. We estimated annual and lifetime reproductive success of female pied flycatchers (Ficedula hypoleuca) and applied capture–mark–recapture models to analyse annual survival rates in relation to the patterns of expression (absence/presence) of an ornament displayed by all males and a fraction of females. Overall, the likelihood of expressing...

Data from: Preservation of RNA and DNA from mammal samples under field conditions

Miguel Camacho-Sanchez, Pablo Burraco, Ivan Gomez-Mestre & Jennifer A. Leonard
Ecological and conservation genetics require sampling of organisms in the wild. Appropriate preservation of the collected samples, usually by cryostorage, is key to the quality of the genetic data obtained. Nevertheless, cryopreservation in the field to ensure RNA and DNA stability is not always possible. We compared several nucleic acid preservation solutions appropriate for field sampling and tested them on rat (Rattus rattus) blood, ear and tail tip, liver, brain and muscle. We compared the...

Data from: Differentiation in neutral genes and a candidate gene in the pied flycatcher: using biological archives to track global climate change

Kerstin Kuhn, Klaus Schwenk, Christiaan Both, David Canal, Ulf S. Johansson, Steven Van Der Mije, Till Töpfer & Martin Päckert
Global climate change is one of the major driving forces for adaptive shifts in migration and breeding phenology and possibly impacts demographic changes if a species fails to adapt sufficiently. In Western Europe, pied flycatchers (Ficedula hypoleuca) have insufficiently adapted their breeding phenology to the ongoing advance of food peaks within their breeding area and consequently suffered local population declines. We address the question whether this population decline led to a loss of genetic variation,...

Data from: Genetics at the verge of extinction: insights from the Iberian lynx

Mireia Casas-Marce, Laura Soriano, José López-Bao & José Godoy
Population viability might become compromised by the loss of genetic diversity and the accumulation of inbreeding resulting from population decline and fragmentation. The Iberian lynx (Lynx pardinus) provides a paradigmatic example of a species at the verge of extinction and, because of the well-documented and different demographic histories of the two remaining populations (Doñana and Andújar), it provides the opportunity to evaluate the performance of analytical methods that are commonly applied to detect genetic signatures...
