Contraction of the ROS Scavenging Enzyme Glutathione S-Transferase Gene Family in Cetaceans

G3: Genes, Genomes, Genetics, 2019
Cetaceans are a group of marine mammals whose ancestors were adaptated for life on land. Life in an aquatic environment poses many challenges for air-breathing mammals. Diving marine mammals have adapted to rapid reoxygenation and reactive oxygen species

An Oligocene (Orellan) Sirenian Fron the Bucatunna Formation of Alabama [PDF]

, 2017
Tertiary sirenians from the New World have been recently reviewed by Reinhart (1976) and Savage (1976). The earliest New World sirenians are known from the presence of pachyostose ribs in Eocene strata of the southeastern United States and from an Eocene

Amazonian manatee critical habitat revealed by artificial intelligence‐based passive acoustic techniques

Remote Sensing in Ecology and Conservation
For many species at risk, monitoring challenges related to low visual detectability and elusive behavior limit the use of traditional visual surveys to collect critical information, hindering the development of sound conservation strategies.

Agonistic interactions initiated by adult bottlenose dolphins on Antillean manatee calves in the Caribbean Sea.

PLoS ONE
The dynamics and drivers of inter-species interactions in the wild are poorly understood, particularly those involving social animal species. Inter-species interactions between cetaceans and sirenians have rarely been documented and investigated.

Sexing Sirenians: Validation of Visual and Molecular Sex Determination in both Wild Dugongs (Dugong dugon) and Florida Manatees (Trichechus manatus latirostris).

, 2009
Sexing wild marine mammals that show little to no sexual dimorphism is challenging. For sirenians that are difficult to catch or approach closely, molecular sexing from tissue biopsies offers an alternative method to visual discrimination.

Charting the course for management: a global analysis of effects of vessels on marine megafauna

npj Ocean Sustainability
Vessel traffic represents one of the most pervasive and escalating sources of disturbance in marine environments, affecting organisms through noise, physical presence, habitat degradation, collisions, and pollution.
