Escalation of threats to marine turtles [PDF]
Oryx, 1992 Many, if not all, marine turtle populations world-wide have become seriously depleted by the impact of numerous factors over the years. Populations of marine turtles are now classified as endangered or threatened. National and international legislation designed to protect sea turtles has been unsuccessful and, despite evergrowing interest, there is ...

Nasal soft‐tissue anatomy of Triceratops and other horned dinosaurs
The 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 ...

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

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

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

Clade‐wide morphological and functional variation of the sauropsid columella
The Anatomical Record, EarlyView.Abstract The columella (=stapes) is the middle ear bone of reptiles that transmits vibrations from the environment to the inner ear. It has been shown to exhibit extensive interspecific morphological disparity in several clades; however, its morphological variation and associated functional consequences remain poorly described.
