The effect of biologging systems on reproduction, growth and survival of adult sea turtles

open access: yesMovement Ecology, 2019
Background Telemetry and biologging systems, ‘tracking’ hereafter, have been instrumental in meeting the challenges associated with studying the ecology and behaviour of cryptic, wide-ranging marine mega-vertebrates.

A long-term decline in the abundance of endangered leatherback turtles, Dermochelys coriacea, at a foraging ground in the California Current Ecosystem

open access: yesGlobal Ecology and Conservation, 2020
Pacific leatherback turtles (Dermochelys coriacea) are critically endangered, and declines have been documented at multiple nesting sites throughout the Pacific. The western Pacific leatherback forages in temperate and tropical waters of the Indo-Pacific

The effects of vessel speed and size on the lethality of strikes of large whales in U.S. waters

open access: yesFrontiers in Marine Science
Vessel strikes are a substantial source of mortality for large whales worldwide and may pose conservation threats for small populations. Model-based estimates of mortality rates, which inform management strategies to reduce vessel strike mortality ...

Change of perspective: using aerial surveys to identify human-turtle interactions in the Ningaloo Marine Park [PDF]

open access: yes, 2009
Shore-based turtle tourism is emerging as a popular activity for independent travellers during the summer months in the Ningaloo Marine Park, yet little is known about the spatial extent of human-turtle interactions and their impact on nesting marine ...

Nasal soft‐tissue anatomy of Triceratops and other horned dinosaurs

open access: yesThe Anatomical Record, EarlyView.
Abstract Although ceratopsid dinosaurs possess a characteristically hypertrophied narial region, soft‐tissue anatomy associated with such a skeletal structure and their biological significance remain poorly understood. The present study provides the first comprehensive hypothesis on the soft‐tissue anatomy in the ceratopsid rostrum based on the Extant ...

Killer whales in the Gulf of Mexico and North Atlantic off the Southeastern United States

open access: yesFrontiers in Marine Science
Killer whales occur in the Gulf of Mexico (GoMex) and the North Atlantic, including off the southeastern United States (SEUS). Data from cetacean surveys during 1990 – 2021 and other sources were combined to assess killer whale biology, including spatial

Marine mammals and sea turtles listed under the U.S. Endangered Species Act are recovering.

open access: yesPLoS ONE, 2019
The U.S. Endangered Species Act (ESA) is a powerful environmental law protecting imperiled plants and animals, and a growing number of marine species have been protected under this law as extinction risk in the oceans has increased.

Effects of Variability in Ship Traffic and Whale Distributions on the Risk of Ships Striking Whales

open access: yesFrontiers in Marine Science, 2020
Assessments of ship-strike risk for large whales typically use a single year of ship traffic data and averaged predictions of species distributions. Consequently, they do not account for variability in ship traffic or species distributions.
