Data from: The effect of pollination mode on seed performance of Gentiana lutea: a laboratory evaluation of seed germinability

Martina Rossi, Alessandro Fisogni & Marta Galloni
Gentiana lutea L. (yellow gentian, Gentianaceae) is a protected orophyte of central and southern Europe, mainly threatened by the uncontrolled collection of its rhizome, used in traditional medicine and for liquor production. The species is self-compatible, but outcrossing mediated by pollinators is needed to obtain a viable progeny. In this study, we considered five natural populations belonging to the four subspecies of G. lutea. We performed controlled pollinations in the field (self- versus cross-pollination) followed...

Data from: Habitat continuity and stepping-stone oceanographic distances explain population genetic connectivity of the brown alga Cystoseira amentacea

Roberto Buonomo, Jorge Assis, Francisco Fernandes, Aschwin H. Engelen, Laura Airoldi & Ester A. Serrão
Effective predictive and management approaches for species occurring in a metapopulation structure require good understanding of inter-population connectivity. In this study we ask whether population genetic structure of marine species with fragmented distributions can be predicted by stepping-stone oceanographic transport and habitat continuity, using as model an ecosystem-structuring brown alga, Cystoseira amentacea var. stricta. To answer this question, we analyzed the genetic structure and estimated the connectivity of populations along discontinuous rocky habitat patches in...

Data from: Assessing environmental pollution in birds: a new methodological approach for interpreting bioaccumulation of trace elements in feather shafts using geochemical sediment data

Fabrizio Borghesi, Enrico Dinelli, Francesca Migani, Arnaud Béchet, Maunel Rendón-Martos, Juan A. Amat, Simone Sommer & Mark A. F. Gillingham
Environmental trace element composition can have an important impact on ecosystem and population health as well individual fitness. Therefore, carefully assessing bioaccumulation of trace elements is central to studies investigating the ecological impact of pollution. Colonial birds are important bioindicators since non-invasive sampling can easily be achieved through sampling of chick feathers, which controls for some confounding factors of variability (age and environmental heterogeneity). However, an additional confounding factor, external contamination (ExCo), which remains even...

Data from: Population connectivity and phylogeography of the Mediterranean endemic skate Raja polystigma and evidence of its hybridization with the parapatric sibling R. montagui

Alessia Cariani, ED Farrell, P Carbonara, G Garofalo, M Stagioni, F Tinti, F Fiorentino, N Frodella, A Veloná, R Cannas & MC Follesa
The genetic structure and population connectivity of the Mediterranean endemic speckled skate Raja polystigma were investigated in 10 population samples (N = 232) at 7 exon-primed nuclear microsatellites and at 3 mitochondrial DNA sequence markers. The phylogeographic and population genetic analyses revealed that R. polystigma in the western and central Mediterranean represents a near-panmictic population, with a subtle but significant mitochondrial divergence of the Adriatic deme. Nuclear genotypes revealed that 2.5% of the total individuals...

Data from: Role of selection and gene flow in population differentiation at the edge vs. interior of the species range differing in climatic conditions

Sergei Volis, Danara Ormanbekova & Irina Shulgina
Evaluating the relative importance of neutral and adaptive processes as determinants of population differentiation across environments is a central theme of evolutionary biology. We applied the QST-FST comparison flanked by a direct test for local adaptation to infer the role of climate-driven selection and gene flow in population differentiation of an annual grass Avena sterilis in two distinct parts of the species range, edge and interior, which represent two globally different climates, desert and Mediterranean....
