Integrating telemetry and point observations to inform management and conservation of migratory marine species

Ecosphere, Volume 14, Issue 1, January 2023., 2023
Abstract Species distribution models have been widely used in both terrestrial and marine systems, and applications have included invasive species management, evaluating potential effects of climate change, and conservation. Generally, only a single type of data can be accommodated within the model structures used, which may lead to higher uncertainty ...

Recent trends in abundance and fishing pressure of agency‐assessed small pelagic fish stocks

Fish and Fisheries, Volume 23, Issue 6, Page 1313-1331, November 2022., 2022
Abstract Small pelagic fishes are used for human consumption, fishmeal and fish oil. They constitute 25% of global fish catch and have been of considerable conservation concern because of their intermediate position in aquatic food webs, often being a dominant dietary component of marine predators. This paper provides an overview of trends in abundance

Climate change adaptation in Central America: A review of the national policy efforts

Latin American Policy, Volume 13, Issue 2, Page 276-327, November 2022., 2022
Abstract The latest comparative studies of climate policies reinforce the fundamental importance of employing adaptation planning alongside national development strategies. While these studies are necessary to document and share the knowledge of the practices and experiences undertaken at the national level, documents are still scarce on regions of ...

Synthesis of Batrachochytrium dendrobatidis infection in South America: amphibian species under risk and areas to focus research and disease mitigation

Ecography, Volume 2022, Issue 7, July 2022., 2022
Amphibian chytridiomycosis, caused by Batrachochytrium dendrobatidis (Bd), has been recognized as the infectious disease causing the most catastrophic loss of biodiversity known to science, with South America being the most impacted region. We tested whether Bd prevalence is distributed among host taxonomy, ecoregion, conservation status and habitat ...

Timing and magnitude of climate‐driven range shifts in transboundary fish stocks challenge their management

Global Change Biology, Volume 28, Issue 7, Page 2312-2326, April 2022., 2022
We use model projections to explore the timing and intensity in the distribution of marine fish stocks that are shared across the world's Exclusive Economic Zones (EEZ). Our findings suggest that many shared stocks’ distribution and catch are expected to change in most EEZs by 2030.
