Data from: Telomere length and dynamics predict mortality in a wild longitudinal study

Emma L. B. Barrett, Terry A. Burke, Martijn Hammers, Jan Komdeur & David S. Richardson
Explaining variation in life expectancy between individuals of the same age is fundamental to our understanding of population ecology and life-history evolution. Variation in the length and rate of loss of the protective telomere chromosome caps has been linked to cellular lifespan. Yet, the extent to which telomere length and dynamics predict organismal lifespan in nature is still contentious. Using longitudinal samples taken from a closed population of Acrocephalus sechellensis (Seychelles warblers) studied for over...

Data from: Multiple post-mating barriers to hybridisation in field crickets

Frances Tyler, Xavier A. Harrison, Amanda Bretman, Thor Veen, Rolando Rodríguez-Muñoz & Tom Tregenza
Mechanisms that prevent different species from interbreeding are fundamental to the maintenance of biodiversity. Barriers to interspecific matings, such as failure to recognize a potential mate, are often relatively easy to identify. Those occurring after mating, such as differences in the how successful sperm are in competition for fertilisations, are cryptic and have the potential to create selection on females to mate multiply as a defence against maladaptive hybridization. Cryptic advantages to conspecific sperm may...

Data from: Reproductive conflict in bumblebees and the evolution of worker policing

Worker policing (mutual repression of reproduction) in the eusocial Hymenoptera represents a leading example of how coercion can facilitate cooperation. The occurrence of worker policing in “primitively” eusocial species with low mating frequencies, which lack relatedness differences conducive to policing, suggests that separate factors may underlie the origin and maintenance of worker policing. We tested this hypothesis by investigating conflict over male parentage in the primitively eusocial, monandrous bumblebee, Bombus terrestris. Using observations, experiments, and...
