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.

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.

Vulnerability of marine megafauna to global at‐sea anthropogenic threats

Conservation Biology, Volume 40, Issue 1, February 2026.
Abstract Marine megafauna species are affected by a wide range of anthropogenic threats. To evaluate the risk of such threats, species’ vulnerability to each threat must first be determined. We build on the existing threats classification scheme and ranking system of the International Union for Conservation of Nature (IUCN) Red List of Threatened ...

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 ...

Exploring Marine Mammal Cognition as a Conservation Tool

Marine Mammal Science, Volume 42, Issue 1, January 2026.
ABSTRACT Cognition is an animal's real‐time adaptation system for responding to change. Rapid environmental change, often anthropogenic, is expanding the range and severity of challenges confronting wild animals. Effective conservation requires a multifaceted approach that includes animals' capacities.

Interaction Between Traditional Fishers and the Neotropical Otter Lontra longicaudis (Olfers, 1818) in a Brazilian Amazon Estuary

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 12, December 2025.
ABSTRACT The neotropical otter Lontra longicaudis (Olfers, 1818) is a semi‐aquatic carnivore from the Mustelidae family with a piscivorous habit that interacts with riverine populations because of fishing resources, and this relationship is often negative, especially in the Amazon where fishing represents an important activity for several communities ...

Morphology and function of pinniped necks: The long and short of it

The Anatomical Record, Volume 308, Issue 12, Page 3175-3185, December 2025.
Abstract Terrestrial vertebrates from at least 30 distinct lineages in both extinct and extant clades have returned to aquatic environments. With these transitions came numerous morphological adaptations to accommodate life in water. Relatively little attention has been paid to the cervical region when tracking this transition.

Fossil axial skeletal walrus material from the North Sea and the estuary of the Schelde, and a fossil Sirenian rib (Mammalia, Carnivora; Sirenia) [PDF]

, 1999
Ten fossil odobenid remains, and a fossil sirenian rib, encountered by us in a public and in a private collection since the publication of some earlier papers, are described and discussed. All fossils belong, anatomically, to the axial skeleton.
