Discrete but variable structure of animal societies leads to the false perception of a social continuum
(2016)
Animal societies are typically divided into those in which reproduction within a group is monopolized by a single female versus those in which it is shared among multiple females. It remains controversial, however, whether ...
No early gender effects on energetic status and life history in a salmonid
(2015)
Throughout an organism’s early development, variations in physiology and behaviours may have long lasting consequences on individual life histories. While a large part of variation in critical life-history transitions ...
Effects of habitat structure and land use intensity on the genetic structure of the grasshopper species Chorthippus parallelus
(2014)
Land-use intensity (LUI) is assumed to impact the genetic structure of organisms. While effects of landscape structure on the genetics of local populations have frequently been analysed, potential effects of variation in ...
Are genes faster than crabs?
(2014)
Biological invasions offer unique opportunities to investigate evolutionary dynamics at the peripheries of expanding pop-ulations. Here, we examine genetic patterns associated with admixture between two distinct invasive ...
Highly contrasted responses of Mediterranean octocorals to climate change along a depth gradient
(2015)
Climate change has a strong impact on marine ecosystems, including temperate species. Analysing the diversity of thermotolerance levels within species along with their genetic structure enables a better understanding of ...
Dramatic niche shifts and morphological change in two insular bird species
(2015)
Colonizations of islands are often associated with rapid morphological divergence. We present two previously unrecog-nized cases of dramatic morphological change and niche shifts in connection with colonization of tropical ...
Opsin transcripts of predatory diving beetles
(2015)
The regressive evolution of eyes has long intrigued biologists yet the genetic underpinnings remain opaque. A system of discrete aquifers in arid Australia provides a powerful comparative means to explore trait regression ...
Mid winter temperatures, not spring temperatures, predict breeding phenology in the European starling Sturnus vulgaris
(2015)
In many species, empirical data suggest that temperatures less than 1 month before breeding strongly influence laying date, consistent with predictions that short lag times between cue and response are more reliable, ...
Increased natural mortality at low abundance can generate an Allee effect in amarine fish
(2014)
Negative density dependent regulation of population dynamics promotes population growth at low abundance and is therefore vital for recovery following depletion. Inversely, any process that reduces the compensatory ...
Pre-zygotic isolation in the macroalgal genusFucus from four contact zones spanning 100–10 000 years
(2015)
Hybrid zones provide an ideal natural experiment to study the selective forces driving evolution of reproductive barriers and speciation. If hybrid offspring are less fit than the parental species, pre-zygotic isolating ...
