Being at the Western fringe of Europe, Iberia had a peculiar prehistory and a complex pattern of Neolithization. A few studies, all based on modern populations, reported the presence of DNA of likely African origin in this region, generally concluding it was the result of recent gene flow, probably during the Islamic period. Here we provide evidence of much older gene flow from Africa to Iberia by sequencing whole genomes from four human remains from...

Dietary stress increases the total opportunity for sexual selection and modifies selection on condition-dependent traits

Silvia Cattelan, Jonathan P. Evans, Francisco Garcia-Gonzalez, Elisa Morbiato & Andrea Pilastro
Although it is often expected that adverse environmental conditions depress the expression of condition-dependent sexually-selected traits, the full consequences of environmental change for the action of sexual selection, in terms of the opportunity for total sexual selection and patterns of phenotypic selection, are unknown. Here we show that dietary stress in guppies, Poecilia reticulata, reduces the expression of several sexually-selected traits and increases the opportunity for total sexual selection (standardized variance in reproductive success) in...

Data from: Diversity patterns of native and exotic fish species suggest homogenization processes, but partly fail to highlight extinction threats

Anna Gavioli, Marco Milardi, Giuseppe Castaldelli, Elisa Anna Fano & Janne Soininen
Exotic species are a major threat to biodiversity and have modified native communities worldwide. Invasion processes have been extensively studied, but studies on species richness and beta diversity patterns of exotic and native species are rare. We investigate such patterns among exotic and native fish communities in upland and lowland rivers to explore their relationship with environmental drivers. Location: Northern Italy. Exotic and native fish beta diversity patterns were investigated separately in lowland and upland...

Data from: Palaeobiogeography and evolutionary patterns of the larger foraminifer Borelis de Montfort (Borelidae)

Davide Bassi, Juan Carlos Braga, Giovanni Di Domenico, Johannes Pignatti, Sigal Abramovich, Pamela Hallock, Janine Koenen, Zoltan Kovacs, Martin R. Langer, Giulio Pavia & Yasufumi Iryu
The palaeobiogeography of the alveolinoid Borelis species reveals the evolutionary patterns leading to the two extant representatives, which occur in shallow-water tropical carbonate, coral reef-related settings. Type material and new material of fossil Borelis species, along with Recent specimens were studied to assess their taxonomic status, species circumscriptions (based on proloculus size, occurrence of Y-shaped septula, and the index of elongation), palaeobiogeography and evolutionary dynamics. The species dealt with here are known from exclusively fossil...

Data from: Differential effects of soil chemistry on the foliar resorption of nitrogen and phosphorus across altitudinal gradients

Renato Gerdol, Paola Iacumin & Lisa Brancaleoni
1.Nutrient resorption from senescing leaves prior to litterfall is a strategy for nutrient conservation in vascular plants. However, the mechanisms through which soil fertility and/or foliar nutrient status affect nutrient resorption are not yet fully known. 2.We used two 1000 m‐wide altitudinal gradients on two different bedrock types (carbonate and silicate) for analysing the interactive effects of temperature and soil chemistry on the resorption efficiency of two major nutrients, nitrogen (N) and phosphorus (P). Our...
