Accumulation of Heavy Metals in Franciscanas from Buenos Aires Province, Argentina [PDF]
, 2002 Marine mammals accumulate heavy metals in their tissues at different concentrations according to trophic levels and environmental conditions. The franciscana (Pontoporia blainvillei) is a small coastal species inhabiting the marine and estuarine areas of

Broadening the semiaquatic scene: Quantification of long bone microanatomy across pinnipeds
The Anatomical Record, EarlyView.Abstract Investigations of bone microanatomy are commonly used to explore lifestyle strategies in vertebrates. While distinct microanatomical limb bone features have been established for exclusively aquatic and terrestrial lifestyles, identifying clear patterns for the semiaquatic lifestyle remains more challenging.

Summing the strokes: energy economy in northern elephant seals during large-scale foraging migrations. [PDF]
, 2015 BackgroundThe energy requirements of free-ranging marine mammals are challenging to measure due to cryptic and far-ranging feeding habits, but are important to quantify given the potential impacts of high-level predators on ecosystems.

The Anatomical Record, EarlyView.Abstract Scientists have been captivated by the ability to regenerate, focusing on uncovering the mechanisms of epimorphic regeneration and applying them to human medicine. The axolotl (Ambystoma mexicanum) has become the most intensively studied model in tetrapod regeneration research, particularly concerning limb regeneration.

Ecology and Evolution, 2020 It is widely accepted that obligate aquatic mammals, specifically toothed whales, rely relatively little on olfaction. There is less agreement about the importance of smell among aquatic mammals with residual ties to land, such as pinnipeds and sea ...

Energetics of locomotion by the Australian Water Rat (Hydromys Chrysogaster): A comparison of swimming and running in a semi-aquatic mammal [PDF]
, 1999 © The Company of BiologistsSemi-aquatic mammals occupy a precarious evolutionary position, having to function in both aquatic and terrestrial environments without specializing in locomotor performance in either environment.

The Anatomical Record, EarlyView.Abstract The study of morphological evolution is fundamentally tied to ontogeny, yet studies of these heterochronic processes in the fossil record are rare. Fossils belonging to an ontogenetic series are difficult to assign to an ontogenetic stage due to inconsistent proxies for skeletal ages, challenging to taxonomically assign due to morphological ...

Abstract Marine mammals include species that depend on the ocean for all or part of their life needs: mysticetes (baleen whales), odontocetes (toothed whales, dolphins, and porpoises), pinnipeds (seals, sea lions, fur seals, and walruses), sirenians (manatees and dugongs), and the marine carnivores (sea otters and polar bears).
