Habitat modeling of Irrawaddy dolphins (Orcaella brevirostris) in the Eastern Gulf of Thailand. [PDF]

Ecol Evol, 2020
We investigated the habitat of a previously unstudied group of endangered Irrawaddy dolphins (Orcaella brevirostris) in the eastern Gulf of Thailand. Depth and temperature emerged as the most important predictors of dolphin presence and group size. Using our results, we generated a map of dolphin high‐use areas that can be used to inform conservation ...

Identifying the current and future status of freshwater connectivity corridors in the Amazon Basin

Conservation Science and Practice, Volume 5, Issue 1, January 2023., 2023
Freshwater connectivity corridors of the Amazon Basin are critical to maintain river services and biodiversity. Among rivers >500 km in length, there are currently 93 freshwater connectivity corridors (FCCs) that are either free‐flowing or of good connectivity status; one‐fifth of these FCCs would lose their free‐flowing status with buildout of ...

By‐catch risk for toothed whales in global small‐scale fisheries

Fish and Fisheries, Volume 22, Issue 6, Page 1155-1159, November 2021., 2021
Abstract Fisheries by‐catch poses the single greatest threat to cetacean (whales, dolphins and porpoises) populations. Despite this, by‐catch of cetaceans does not receive proportionate levels of research or management effort. The contribution of small‐scale fisheries to cetacean by‐catch is generally overlooked because of the extreme data paucity in ...

Combined effects of life‐history traits and human impact on extinction risk of freshwater megafauna

Conservation Biology, Volume 35, Issue 2, Page 643-653, April 2021., 2021
Abstract Megafauna species are intrinsically vulnerable to human impact. Freshwater megafauna (i.e., freshwater animals ≥30 kg, including fishes, mammals, reptiles, and amphibians) are subject to intensive and increasing threats. Thirty‐four species are listed as critically endangered on the International Union for Conservation of Nature (IUCN).
