TAXONOMIC STATUS OF THE GENUSSOTALIA: SPECIES LEVEL RANKING FOR “TUCUXI” (SOTALIA FLUVIATILIS) AND “COSTERO” (SOTALIA GUIANENSIS) DOLPHINS [PDF]

Marine Mammal Science, 2007
AbstractDolphins of the genusSotaliaare found along the Caribbean and Atlantic coasts of Central and South America and in the Amazon River and most of its tributaries. At present, the taxonomy of these dolphins remains unresolved. Although five species were described in the late 1800s, only one species is recognized currently (Sotalia fluviatilis) with

Reproductive morphology of female Guiana dolphins (Sotalia guianensis) [PDF]

Anais da Academia Brasileira de Ciências, 2015
The reproductive morphology of cetaceans is poorly studied and, despite the large number of strandings, reports on this subject are scarce due to access to carcasses mostly in an advanced state of decomposition.

Initial description of Major Histocompatibility Complex variation at two Class II loci (DQA-DQB) in Sotalia fluviatilis and Sotalia guianensis [PDF]

Latin American Journal of Aquatic Mammals, 2010
ABTRACT: Los genes del complejo mayor de histocompatibilidad (MHC) desempeñan un papel clave en el inicio de la respuesta inmune en los vertebrados con mandíbula. La variación en los loci del MHC se puede utilizar como un indicador de la "salud" genética de las poblaciones naturales y ofrece información sobre la posible susceptibilidad a la epizootia ...

Population Structure of Riverine and Coastal Dolphins Sotalia fluviatilis and Sotalia guianensis: Patterns of Nuclear and Mitochondrial Diversity and Implications for Conservation

Journal of Heredity, 2018
Coastal and freshwater cetaceans are particularly vulnerable due to their proximity to human activity, localized distributions, and small home ranges. These species include Sotalia guianensis, found in the Atlantic and Caribbean coastal areas of central and South America, and Sotalia fluviatilis, distributed in the Amazon River and tributaries.

Herpesviral infection in a Guiana dolphin ( Sotalia guianensis ) from the northern coast of Brazil

Journal of Veterinary Diagnostic Investigation, 2017
We describe herein herpesvirus-associated genital lesions in a Guiana dolphin ( Sotalia guianensis) from the northern Brazilian coast. Papillary lesions on the vulva, with epithelial hyperplasia, swollen keratinocytes, and intranuclear inclusions, were positive for a herpesvirus ( Gammaherpesvirinae subfamily).

Molecular sexing of tucuxi dolphins (Sotalia guianensis and Sotalia fluviatilis) using samples from biopsy darting and decomposed carcasses [PDF]

Genetics and Molecular Biology, 2007
We tested the zinc-finger sex chromosome-linked genes Zfx/Zfy and the sex-determining region Y (Sry) genes for gender determination of biopsy samples from marine and riverine tucuxi dolphins (Sotalia guianensis and S. fluviatilis).
