Evolution of the vaquita/totoaba socio‐ecological system in the Upper Gulf of California, Mexico

Ecosphere
The Upper Gulf of California (UGC) hosts a rich marine biodiversity. Complex climatic processes generate high biological productivity enabling the use of resources in a complex socio‐ecological processes (SEPs). Through a literature review, evolution and

Harbor porpoise losing its edge: Genetic time series suggests a rapid population decline in Iberian waters over the last 30 years. [PDF]

Ecol Evol, 2023
The Iberian harbor porpoises form a small and semi‐isolated population belonging to a distinctive ecotype adapted to the upwelling system in the southern European Atlantic waters. Here, we analyzed the mitochondrial genetic variation for a sampling spanning over the past 30 years and reported a dramatic decline in diversity.

Whole Genome Analyses of the Endangered Northern Abalone (<i>Haliotis kamtschatkana</i>) Reveal Population Differentiation and a Genomic Signature of a Dramatic Population Decline. [PDF]

Evol Appl
ABSTRACT Despite widespread declines of many wildlife species, the effects of population decline on the genome and the recovery potential of affected species are still poorly understood, especially beyond a few charismatic species. The Northern abalone (or Pinto abalone; Haliotis kamtschatkana) is a marine gastropod mollusk of social, cultural and ...

Leveraging Synteny to Generate Reference Genomes for Conservation: Assembling the Genomes of Hector's and Māui Dolphins. [PDF]

Mol Ecol Resour
ABSTRACT Escalating concern regarding the impacts of reduced genetic diversity on the conservation of endangered species has spurred efforts to obtain chromosome‐level genomes through consortia such as the Vertebrate Genomes Project. However, assembling reference genomes for many threatened species remains challenging due to difficulties obtaining ...

Vaquitas and gillnets: Mexico’s ultimate cetacean conservation challenge

Endangered Species Research, 2013
There is a high risk that incidental mortality (bycatch) in gillnets will lead to extinction of the vaquita Phocoena sinus, a small porpoise endemic to Mexico’s northern Gulf of California. A zoned Biosphere Reserve established in 1993 proved ineffective

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 ...

Valoración económica para la protección socioambiental de la vaquita marina, una especie endémica

Región y Sociedad, 2017
The impact of irrational human practices on the environment makes it indispensable to implement measures, such as the Upper Gulf of California and Colorado River Delta Biosphere Reserve, in order to preserve the natural environment and habitats, and thus

Can the Vaquita Be Saved From Extinction?

Human-Wildlife Interactions, 2018
The vaquita (Phocoena sinus) is considered the world’s most endangered marine mammal. It is the smallest member of the porpoise family endemic to the upper part of the Gulf of California.

An Online Survey of Public Knowledge, Attitudes, and Perceptions Toward Whales and Dolphins, and Their Conservation

Frontiers in Marine Science, 2018
In 2015, an online survey was conducted to investigate public attitudes and perceptions toward key cetacean (whale, dolphin, and porpoise) conservation and “hot topic” issues such as legislative protection and whaling (n = 858).
