How to estimate age of old bottlenose dolphins (Tursiops truncatus); by tooth or pectoral flipper?

open access: yesFrontiers in Marine Science, 2023
Multiple techniques have been used for estimating age in bottlenose dolphins (Tursiops truncatus). The longest established technique is via counts of growth later groups (GLGs) in the longitudinal section of an extracted mandibular tooth.

Tracking arctic marine mammal resilience in an era of rapid ecosystem alteration

open access: yesPLoS Biology, 2018
Global warming is significantly altering arctic marine ecosystems. Specifically, the precipitous loss of sea ice is creating a dichotomy between ice-dependent polar bears and pinnipeds that are losing habitat and some cetaceans that are gaining habitat ...

People - Marine Mammal Interactions [PDF]

open access: yes, 2017
Our relationships with marine mammals are complex. We have used them as resources, and in some places this remains the case; viewed them as competitors and culled them (again ongoing in some localities); been so captivated and intrigued by them that we have taken them into captivity for our entertainment; and developed a lucrative eco-tourism activity ...

Phospholipid Levels Predict the Tissue Distribution of Poly- and Perfluoroalkyl Substances in a Marine Mammal.

open access: yesEnvironmental Science and Technology Letters, 2019
Exposure to poly- and perfluoroalkyl substances (PFASs) has been linked to many negative health impacts in humans and wildlife. Unlike neutral hydrophobic organic pollutants, many PFASs are ionic and have been hypothesized to accumulate in both ...

Linkages between human health and ocean health: a participatory climate change vulnerability assessment for marine mammal harvesters [PDF]

open access: yesInternational Journal of Circumpolar Health, 2013
Background. Indigenous residents of Alaska’s Bering Strait Region depend, both culturally and nutritionally, on ice seal and walrus harvests. Currently, climate change and resultant increases in marine industrial development threaten these species

Estimates of Marine Mammal, Sea Turtle, and Seabird Mortality in the California Drift Gillnet Fishery for Swordfish and Thresher Shark, 1996–2002 [PDF]

open access: yes, 2004
Estimates of incidental marine mammal, sea turtle, and seabird mortality in the California drift gillnet fishery for broadbill swordfish, Xiphias gladius, and common thresher shark, Alopias vulpinus, are summarized for the 7-year period, 1996 to 2002 ...

A Universal Biomimetic Approach for Making Artificial Antigen‐Presenting Cells for T Cell Activation

open access: yesAdvanced Functional Materials, EarlyView.
This study shows a biomimetic silica microcapsule (SMC) fabrication method under mild conditions for making artificial antigen‐presenting cells (aAPCs). Inspired by marine biomineralization, peptide‐mediated biosilicification enables silica shell formation on emulsion templates. The resulting SMCs possess a core–shell structure, controlled fluorescence

Capturing foraging and resting behavior using nested multivariate Markov models in an air-breathing marine vertebrate

open access: yesMovement Ecology, 2018
Background Matching animal movement with the behaviors that shape life history requires a rigorous connection between the observed patterns of space use and inferred behavioral states. As animal-borne dataloggers capture a greater diversity and frequency

Rescue, rehabilitation, and release of marine mammals: An analysis of current views and practices. [PDF]

open access: yes, 1996
Stranded marine mammals have long attracted public attention. Those that wash up dead are, for all their value to science, seldom seen by the public as more than curiosities.
