Conservation Biology (2007)
The recent likely extinction of the baiji (Chinese river dolphin [Lipotes vexillifer]) (Turvey et al. 2007) makes the vaquita (Gulf of California porpoise [Phocoena sinus]) the most endangered cetacean. The…
Genetic drift vs. natural selection in a long-term small isolated population: major histocompatibility complex class II variation in the Gulf of California endemic porpoise (Phocoena sinus)
MUNGUIA-VEGA, ADRIAN; ESQUER-GARRIGOS, YARELI; ROJAS-BRACHO, LORENZO; VAZQUEZ-JUAREZ, RICARDO; CASTRO-PRIETO, AINES; FLORES-RAMIREZ, SERGIO
Molecular Ecology (2007)
Although many studies confirm long-term small isolated populations (e.g. island endemics) commonly sustain low neutral genetic variation as a result of genetic drift, it is less clear how selection on…
The phylogenetic relationships and biogeography of true porpoises (Mammalia: Phocoenidae) based on morphological data
Fajardo-Mellor, Liliana; Berta, Annalisa; Brownell, Robert L.; Boy, Claudia C.; Goodall, R. Natalie P.
Marine Mammal Sci (2006)
Prior studies of phylogenetic relationships among phocoenids based on morphology and molecular sequence data conflict and yield unresolved relationships among species. This study evaluates a comprehensive set of cranial, postcranial,…

LORENZO ROJAS-BRACHO; RANDALL R. REEVES; ARMANDO JARAMILLO-LEGORRETA
Mammal Review (2006)
The vaquita Phocoena sinus is a small porpoise that is endemic to the northern Gulf of California, Mexico. It is the most critically endangered marine small cetacean in the world.…
A review of acoustic surveys and conservations actions for the vaquita
JARAMILLO-LEGORRETA, A.; ROJAS-BRACHO, L.; URBAN, J.
Scientific Committee Meeting Documents (2005)
In the first part of this report we present our results, so far, derived from the application of passive acoustic techniques to study the habitat use of vaquita. In the…
Review of small cetaceans: Distribution, behaviour, migration and threats
Culik, Boris
(2004)
This report summarises the available knowledge on odontocete (toothed whale) distribution, behaviour, migration and threats and was compiled for the Bonn Secretariat of CMS.
Vaquita bycatch in Mexico’s artisanal gillnet fisheries: Driving a small population to extinction
D'agrosa, Caterina; Lennert-Cody, Cleridy E.; Vidal, Omar
Conservation Biology (2000)
The world's most endangered marine cetacean, the vaquita (Phocoena sinus), continues to be caught in small-mesh gillnet fisheries throughout much of its range. We monitored fishing effort and incidental vaquita…
Polydactyly and other features of the manus of the vaquita, Phocoena sinus
Ortega-Ortiz, Joel G.; Villa-Ramirez, Bernardo; Gersenowies, Jorge R.
Marine Mammal Sci (2000)
The vaquita (Phocoena sinus) manus was examined in 16 individuals. The carpus has a proximal row of three bones and a cartilaginous accessory carpal element distocaudal to the ulna. Five…
Examining the risk of inbreeding depression in a naturally rare cetacean, the vaquita (Phocoena sinus)
Taylor, Barbara L.; Rojas-Bracho, Lorenzo
Marine Mammal Sci (1999)
Uncertainty about the magnitude of various risks facing endangered species can paralyze conservation action. The vaquita is a naturally rare porpoise that has declined to the low hundreds of individuals…
A new abundance estimate for vaquitas: First step for recovery
Jaramillo-Legorreta, Armando M.; Rojas-Bracho, Lorenzo; Gerrodette, Tim
Marine Mammal Sci (1999)
A line-transect survey specifically designed to estimate vaquita (Phocoena sinus) abundance over its entire range was carried out by three boats in the summer of 1997. There was a total…
