A Bayesian integrated population dynamics model to analyze data for protected species [PDF]

Animal Biodiversity and Conservation, 2004
Managing wildlife-human interactions demands reliable information about the likely consequences of management actions. This requirement is a general one, whatever the taxonomic group.

Avistamientos del delfín manchado, Stenella attenuata (Cetacea: Delphinidae) en Bahía Culebra, Costa Rica, 1999-2000

Revista de Biología Tropical, 2004
Paralelo a un estudio de zooplancton (1999-2000), se hicieron observaciones a bordo de un bote inflable, sobre la presencia o ausencia de delfines a lo largo de un transecto (~8 km long) en la parte central de Bahía Culebra (24 km² ), Golfo de Papagayo ...

Morphology of the Tympano-Periotic Complex in Stranded Odontocetes in Northeast Brazil. [PDF]

J Morphol
This study presents the morphological and morphometric characterization of the tympano‐periotic complex (TPC) in six odontocete species stranded along the northeastern coast of Brazil. A total of 57 TPCs were analyzed, revealing interspecific differences in key anatomical features and supporting taxonomic differentiation.

How is the third jaw joint in whales different? Diverse modes of articulation between the jaws of whales. [PDF]

J Anat
This study conducts the first comprehensive morphological investigation of the mandibular symphysis in whales. Using gross anatomical observation and CT cross‐sectional data, we describe diverse joint morphologies across 74 extant and fossil cetacean taxa. Toothed whales exhibit unfused, partially fused, or fully fused symphyses.

Trophic relationships and habitat preferences of delphinids from the southeastern Brazilian coast determined by carbon and nitrogen stable isotope composition. [PDF]

PLoS ONE, 2013
To investigate the foraging habitats of delphinids in southeastern Brazil, we analyzed stable carbon (δ(13)C) and nitrogen (δ(15)N) isotopes in muscle samples of the following 10 delphinid species: Sotalia guianensis, Stenella frontalis, Tursiops ...

Back to Water: Signature of Adaptive Evolution in Cetacean Mitochondrial tRNAs [PDF]

, 2016
The mitochondrion is the power plant of the eukaryotic cell, and tRNAs are the fundamental components of its translational machinery. In the present paper, the evolution of mitochondrial tRNAs was investigated in the Cetacea, a clade of Cetartiodactyla ...

Heart development in the spotted dolphin (Stenella attenuata) [PDF]

The Anatomical Record Part A: Discoveries in Molecular, Cellular, and Evolutionary Biology, 2003
AbstractMarine mammals show many deviations from typical mammalian characteristics due to their high degree of specialization to the aquatic environment. In Cetaceans, some of the features of limbs and dentition resemble very ancestral patterns. In some species, hearts with a clearly bifid apex (a feature normally present during mammalian embryogenesis

Ecological Niche Modeling of Three Species of Stenella Dolphins in the Caribbean Basin, With Application to the Seaflower Biosphere Reserve

Frontiers in Marine Science, 2019
Dolphins of the genus Stenella occur in pelagic waters of both tropical and warm-temperate oceans. Three species, the Atlantic spotted dolphin (Stenella frontalis), the pantropical spotted dolphin (S. attenuata), and the spinner dolphin (S. longirostris)
