Characterizing the genetic structure and connectivity between populations of endangered species can be used to inform management actions. In vagile species with high gene flow or recently established populations, such characterizations can be difficult to undertake using traditional genetic markers, and genetic stock identification (GSI) may be confounded by allele-sharing between populations. Loggerhead sea turtles ( Caretta...
Phylogenetic‐Pheromone Associations Obscured by Stabilising Selection and Natal Tree Effect in a Tree‐Killing Bark BeetleNARA Subscribed
Insects are highly reliant on chemical cues such as pheromones to facilitate communication and navigation. Some of the roles of pheromones include attracting and finding mates and conspecifics, and in these cases, we expect stabilising selection to dampen within‐population pheromone variation. On the other hand, standing pheromone variation may lead to barriers to gene flow and saltational shifts that facilitate divergence and...
Assessing the linkage between breeding and non-breeding areas has important implications for understanding the fundamental biology of and conserving animal species. This is a challenging task for marine species, and in sea turtles a combination of stable isotope analysis (SIA) and satellite telemetry has been increasingly used. The Northwest Atlantic (NWA) loggerhead ( Caretta caretta ) Regional Management Unit, one of the lar...
Globally, sea turtle research and conservation efforts are underway to identify important high-use areas where these imperiled individuals may be resident for weeks to months to years. In the southeastern Gulf of Mexico, recent telemetry studies highlighted post-nesting foraging sites for federally endangered green turtles ( Chelonia mydas ) around the Florida Keys. In order to delineate additional areas that may serve as inte...
The distribution, spatial pattern and population dynamics of a species can be influenced by differences in the environment across its range. Spatial variation in climatic conditions can cause local populations to undergo disruptive selection and ultimately result in local adaptation. However, local adaptation can be constrained by gene flow and may favour resident individuals over migrants—both are factors critical to the asse...
We tested for genetic differentiation among six populations of California sea mussels ( Mytilus californianus ) sampled across 4000 km of its geographical range by comparing patterns of variation at four independent types of genetic markers: allozymes, single‐copy nuclear DNA markers, and DNA sequences from the male and female mitochondrial genomes. Despite our extensive sampling and genotyping efforts, we detected no signific...
