Feeding mode drives mandibular shape in extant Delphinidae

Journal of Zoology, Volume 324, Issue 3, Page 187-200, November 2024.
Delphinidae exhibit fascinating morphological adaptations linked to their feeding strategy, biosonar mode and habitat. This study integrates phylogenetic and 2D geometric morphometric analyses to investigate the adaptive significance of mandible morphological variation in response to ecological pressures in Delphinidae.

Placentation in dolphins from the Amazon River Basin: the Boto, Inia geoffrensis, and the Tucuxi, Sotalia fluviatilis [PDF]

, 2007
A recent reassessment of the phylogenetic affinities of cetaceans makes it timely to compare their placentation with that of the artiodactyls. We studied the placentae of two sympatric species of dolphin from the Amazon River Basin, representing two ...

Mitochondrial DNA diversity, differentiation and phylogeography of the South American riverine and coastal dolphins Sotalia fluviatilis and Sotalia guianensis.

Latin American Journal of Aquatic Mammals, 2010
Here we consider the phylogeography and population structure of the South American coastal and riverine dolphins, Sotalia guianensis and Sotalia fluviatilis, based on samples (n = 76) collected across more than 9000km of the species distribution.Phylogenetic reconstruction of 31 distinct haplotypes based on a combined analysis of two mitochondrial gene

Pyrethroid insecticides along the Southwestern Atlantic coast: Guiana dolphin (Sotalia guianensis) as a bioindicator

Science of The Total Environment, 2020
The presence of pyrethroid compounds in hepatic tissue of Guiana dolphins (Sotalia guianensis) is reported for the first time. Twelve pyrethroids were determined in 50 animals from eight locations of the Brazilian coast. The highest average concentration of total pyrethroids (∑PYR) was 1166 ng.g-1 lw, with values ranging from 148 to 5918 ng.g-1 lw, in ...

Molecular Identification of Delphinids and Finless Porpoise (Cetacea) from the Arabian Sea and Bay of Bengal [PDF]

, 2008
The exact number of extant delphinid species from seas around India is still debated and the lack of adequate field keys and reliable inventory has resulted in misidentification of several species. As a part of a project to develop a molecular taxonomy
