Drift versus selection as drivers of phenotypic divergence at small spatial scales: The case of Belgjarskógur threespine stickleback
Sign Up to like & getrecommendations! Published in 2019 at "Ecology and Evolution"
DOI: 10.1002/ece3.5381
Abstract: Abstract Divergence in phenotypic traits is facilitated by a combination of natural selection, phenotypic plasticity, gene flow, and genetic drift, whereby the role of drift is expected to be particularly important in small and isolated… read more here.

Salinity‐induced transcriptome profiles in marine and freshwater threespine stickleback after an abrupt 6‐hour exposure

DOI: 10.1002/ece3.9395
Abstract: Abstract Saltwater and freshwater environments have opposing physiological challenges, yet, there are fish species that are able to enter both habitats during short time spans, and as individuals they must therefore adjust quickly to osmoregulatory… read more here.

DOI: 10.1016/j.jembe.2017.09.013
Abstract: Abstract Endocrine disrupting chemicals (EDCs) like 17α-ethinylestradiol (EE2) are prevalent in aquatic ecosystems worldwide where they have the ability to decrease fitness by altering the ways in which organisms forage, court, and react to predators.… read more here.

DOI: 10.1038/s41598-018-20075-z
Abstract: On March 11, 2011, a large earthquake occurred, causing a tsunami which struck the Pacific coast of northeast Japan. We investigated the ecological and genetic effects of the large tsunami on the threespine stickleback (genus… read more here.

Predation cost of a sexual signal in the threespine stickleback

DOI: 10.1093/beheco/arx080
Abstract: Lay SummaryThe factors that limit sexual signal expression and ensure honest signaling of mate quality are poorly known. We show that predation risk is a cost of the sexually selected red coloration of the threespine… read more here.

Heritability of DNA methylation in threespine stickleback (Gasterosteus aculeatus).

DOI: 10.1093/genetics/iyab001
Abstract: Epigenetic mechanisms underlying phenotypic change are hypothesized to contribute to population persistence and adaptation in the face of environmental change. To date, few studies have explored the heritability of intergenerationally stable methylation levels in natural… read more here.

DOI: 10.1093/icb/icac071
Abstract: Abstract The Threespine Stickleback is ancestrally a marine fish, but many marine populations breed in fresh water (i.e., are anadromous), facilitating their colonization of isolated freshwater habitats a few years after they form. Repeated adaptation… read more here.

DOI: 10.1098/rspb.2017.1667
Abstract: Epigenetic mechanisms such as changes in DNA methylation have the potential to affect the resilience of species to climate change, but little is known about the response of the methylome to changes in environmental temperature… read more here.

DOI: 10.1111/jeb.13035
Abstract: Gene flow is widely thought to homogenize spatially separate populations, eroding effects of divergent selection. The resulting theory of ‘migration–selection balance’ is predicated on a common assumption that all genotypes are equally prone to dispersal.… read more here.

DOI: 10.1111/jeb.14035
Abstract: Sexual signals are shaped by their intended and unintended receivers as well as the signalling environment. This interplay between sexual and natural selection can lead to divergence in signals in heterogeneous environments. Yet, the extent… read more here.
