Integrated animal movement and spatial capture-recapture models: simulation, implementation, and inference

Beth Gardner, Brett McClintock, Sarah Converse & Nathan Hostetter
Over the last decade, spatial capture-recapture (SCR) models have become widespread for estimating demographic parameters in ecological studies. However, the underlying assumptions about animal movement and space use are often not realistic. This is a missed opportunity because ecological questions related to animal space use, habitat selection, and behavior cannot be addressed with most SCR models, despite the fact that the data collected in SCR studies -- individual animals observed at specific locations and times...

Environmental DNA provides quantitative estimates of Pacific hake abundance and distribution in the open ocean.

Andrew Shelton, Ana Ramon-Laca, Abigail Wells, Julia Clemons, Dezhang Chu, Blake Feist, Ryan Kelly, Sandra Parker-Stetter, Rebecca Thomas, Krista Nichols & Linda Park
All species inevitably leave genetic traces in their environments, and the resulting environmental DNA (eDNA) reflects the species present in a given habitat. It remains unclear whether eDNA signals can provide quantitative metrics of abundance on which human livelihoods or conservation successes depend. Here, we report the results of a large eDNA ocean survey (spanning 86,000 km2 to depths of 500m) to understand the abundance and distribution of Pacific hake Merluccius productus, the target of...

Genetic structure and dispersal in peripheral populations of a marine fish (Pacific cod, Gadus macrocephalus) and their importance for adaptation to climate change

Mary Fisher, Thomas Helser, Sukyung Kang, Wooseok Gwak, Michael Canino & Lorenz Hauser
Small and isolated peripheral populations, which are often remnants of glacial refugia, offer an opportunity to determine the magnitude and direction of fine-scale connectivity in high gene flow marine species. When located at the equatorial edge of a species’ range, these populations may also harbor genetic diversity related to survival and reproduction at higher temperatures, a critical resource for marine species facing warming ocean temperatures. Pacific cod (Gadus macrocephalus), a marine fish in the North...
