Assessing the genetic diversity in Argopecten nucleus (Bivalvia: Pectinidae), a functional hermaphrodite species with extremely low population density and self-fertilization: Effect of null alleles. [PDF]

Ecol Evol, 2020
The microsatellite markers exhibited high levels of genetic diversity in the Argopecten nucleus population of Neguanje Bay (Santa Marta, Colombia), but also indicated a high homozygosity, suggesting the occurrence of the self‐fertilization associated with the low‐population densities reported for the species. Abstract Argopecten nucleus is a functional

Linking extinction risk to the economic and nutritional value of sharks in small-scale fisheries. [PDF]

Conserv Biol
Abstract To achieve sustainable shark fisheries, it is key to understand not only the biological drivers and environmental consequences of overfishing, but also the social and economic drivers of fisher behavior. The extinction risk of sharks is highest in coastal tropical waters, where small‐scale fisheries are most prevalent.

Red‐list status and extinction risk of the world's whales, dolphins, and porpoises

Conservation Biology, Volume 37, Issue 5, October 2023., 2023
Abstract To understand the scope and scale of the loss of biodiversity, tools are required that can be applied in a standardized manner to all species globally, spanning realms from land to the open ocean. We used data from the International Union for the Conservation of Nature Red List to provide a synthesis of the conservation status and extinction ...

Effects of forest cover on richness of threatened fish species in Japan

Conservation Biology, Volume 36, Issue 3, June 2022., 2022
Abstract Estuaries––one of the most vulnerable ecosystems globally––face anthropogenic threats, including biodiversity loss and the collapse of sustainable fisheries. Determining the factors contributing to the maintenance of estuarine biodiversity, especially that of fish, is vital for promoting estuarine conservation and sustainability.

Prioritizing forest management actions to benefit marine habitats in data‐poor regions

Conservation Biology, Volume 36, Issue 2, April 2022., 2022
Abstract Land‐use change is considered one of the greatest human threats to marine ecosystems globally. Given limited resources for conservation, we adapted and scaled up a spatially explicit, linked land–sea decision support tool using open access global geospatial data sets and software to inform the prioritization of future forest management ...
