Evolution of Hybrid Inviability Associated With Chromosome Fusions

open access: yesMolecular Ecology, EarlyView.
ABSTRACT Chromosomal rearrangements, such as inversions, have received considerable attention in the speciation literature due to their hampering effects on recombination. Less is known about how other rearrangements, such as chromosome fissions and fusions, can affect the evolution of reproductive isolation. Here, we use crosses between populations of

The Roles of Plasticity and Selection in Rapid Phenotypic Changes at the Pacific Oyster Invasion Front in Europe

open access: yesMolecular Ecology, EarlyView.
ABSTRACT Invasive species present significant management challenges worldwide due to their ability to rapidly adapt to novel environments. The Pacific oyster Crassostrea gigas, a globally distributed invasive species, arrived in western Sweden in 2006 but has not yet colonised the low salinity waters of the Baltic Sea, presumably because low salinities

The Spatial Spread and the Persistence of Gene Drives Are Affected by Demographic Feedbacks, Density Dependence and Allee Effects

open access: yesMolecular Ecology, EarlyView.
ABSTRACT Homing gene drive alleles bias their own transmission by converting wild‐type alleles into drive alleles. If introduced in a natural population, they might fix within a relatively small number of generations, even if they are deleterious.

Joint Estimation of Paternity, Sibships and Pollen Dispersal in a Snapdragon Hybrid Zone

open access: yesMolecular Ecology, EarlyView.
ABSTRACT Inferring genealogical relationships of wild populations is useful because it gives direct estimates of mating patterns and variance in reproductive success. Inference can be improved by including information about parentage shared between siblings, or by modelling phenotypes or population data related to mating.

White Paper on Nutrition Sensing and Ageing

open access: yesNutrition Bulletin, EarlyView.
ABSTRACT Ageing, which is defined as the progressive deterioration of physiological functions, is an inevitable part of the lifecycle. Nevertheless, its progress is believed to be influenced by modifiable factors, one of the most important being dietary intake.
