First Description of a Satellite DNA in Manatees’ Centromeric Regions

Frontiers in Genetics, 2021
Trichechus manatus and Trichechus inunguis are the two Sirenia species that occur in the Americas. Despite their increasing extinction risk, many aspects of their biology remain understudied, including the repetitive DNA fraction of their genomes.

First Report of Marinomyxa spp. (Rhizaria: Endomyxa: Phytomyxea) Infection in Seagrasses Halophila beccarii and Halophila decipiens: Supporting Evidence for a Long‐Standing Symbiosis

Plant Pathology, Volume 75, Issue 3, May–June 2026.
A survey of phytomyxid parasites in seagrasses of the genus Halophila reveals previously unrecognised diversity and a widespread presence of Marinomyxa within Halophila meadows, supporting a tight co‐evolutionary relationship between the two genera. ABSTRACT Marinomyxa is a genus of obligate intracellular parasitic protists known to infect tropical ...

Cognition as a Conservation Tool: A Case Study of Florida Manatees and Boat Strikes

Marine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT Boat strikes injure and kill large numbers of Florida manatees (Trichechus manatus latirostris) each year. Management actions taken to mitigate this threat can be potentially enhanced by consideration of manatee cognitive processes. The role of cognition in marine mammal conservation has received little consideration in the literature.

Distilling food web dynamics: top–down and bottom–up drivers of extinction and trophic cascades

Oikos, Volume 2026, Issue 3, March 2026.
Quantifying population dynamics is a fundamental challenge in ecology and evolutionary biology, particularly for species that are cryptic, microscopic, or extinct. Traditional approaches rely on continuous representations of population size, but in many cases, the precise number of individuals is unknowable.

Jaw anatomy of Potamogale velox (Tenrecidae, Afrotheria) with a focus on cranial arteries and the coronoid canal in mammals [PDF]

PeerJ, 2016
Afrotheria is a strongly supported clade within placental mammals, but morphological synapomorphies for the entire group have only recently come to light.

Validation of aerial photogrammetry methods to measure body size, condition and mass in small cetaceans

The Journal of Physiology, Volume 604, Issue 5, Page 1788-1808, 1 March 2026.
Abstract figure legend Unoccupied aerial vehicle (UAV)‐based photogrammetry provides measurements equivalent to traditional hand measurements in bottlenose dolphins. Mass estimates derived from UAV measurements closely match the true body mass of live individuals.

Marine mammal bycatch in gillnet and other entangling net fisheries, 1990 to 2011

Endangered Species Research, 2013
Since the 1970s the role of fishery bycatch as a factor reducing, or limiting the recovery of, marine mammal populations has been increasingly recognized.

Drivers of Habitat Selection by the Endangered Greater Caribbean Manatee in Coastal‐Marine Ecosystems

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 1, January 2026.
ABSTRACT Habitat selection is a fundamental aspect of animal movement and behaviour, involving strategies that influence population regulation, species interactions, community structure and the generation and preservation of biodiversity. The Greater Caribbean Manatee is a megaherbivorous aquatic mammal with high environmental plasticity, found in a ...
