Evidence for distinct coastal and offshore communities of bottlenose dolphins in the north east Atlantic. [PDF]

, 2015
Bottlenose dolphin stock structure in the northeast Atlantic remains poorly understood. However, fine scale photo-id data have shown that populations can comprise multiple overlapping social communities.

Resumption of traditional drive hunting of dolphins in the Solomon Islands in 2013 [PDF]

Royal Society Open Science, 2015
The ‘drive hunting’ of dolphins has a long history in the Solomon Islands, specifically at the island of Malaita. In 2010, the most active village, Fanalei, suspended hunting in exchange for financial compensation from an international non-governmental ...

The hydrodynamics of dolphin drafting [PDF]

Journal of Biology, 2004
Drafting in cetaceans is defined as the transfer of forces between individuals without actual physical contact between them. This behavior has long been surmised to explain how young dolphin calves keep up with their rapidly moving mothers. It has recently been observed that a significant number of calves become permanently separated from their mothers

Biodegradable Sodium Alginate Films Incorporated With Microcapsules of Amazonian Buriti Fruit Oil (Mauritia flexuosa L.)

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT Pollution caused by plastic polymers is a growing concern as it compromises biodiversity and human health. As a sustainable solution, developing biodegradable films, such as sodium alginate, is promising due to its low vapor permeability, flexibility, gloss, and cost‐effectiveness.

Nocturnal Vocal Activity in Captive Bottlenose Dolphins (Tursiops truncatus): Could Dolphins have Presleep Choruses? [PDF]

Animal Behavior and Cognition, 2014
Nocturnal vocal activity in dolphins is often thought to be associated with feeding activity. However, when no food resources are available dolphins spend their time for the most part resting/sleeping.

The riddle of the river dolphins [PDF]

Current Biology, 2001
River dolphins are some of the world's least-known and endangered species of mammals. Although better-known marine dolphins are found in estuaries, river dolphins represent four distinct genera each inhabiting different river basins such as the Amazon, Ganges, Indus and Yangtze. But their relationship to each other and other cetaceans has been puzzling

Predicting ecology and hearing sensitivities in Parapontoporia—An extinct long‐snouted dolphin

The Anatomical Record, EarlyView.
Abstract Analyses of the cetacean (whale and dolphin) inner ear provide glimpses into the ecology and evolution of extinct and extant groups. The paleoecology of the long‐snouted odontocete (toothed whale) group, Parapontoporia, is primarily marine with its depositional context also suggesting freshwater tolerance.
