Morphometric and Paleobiological Insights Into Pleistocene Sicilian Wolf Populations

open access: yesActa Zoologica, EarlyView.
ABSTRACT The Pleistocene wolves (Canis lupus) from Sicily represent one of the few known insular populations of this species from that time period. Despite their potential relevance for understanding carnivore adaptations in insular contexts, no dedicated study has previously investigated their morphology and evolutionary significance.

Bubble blasts! An adaptation for buoyancy regulation in shallow foraging gray whales

open access: yesEcology and Evolution
Foraging efficiency is key to animal fitness. Consequently, animals evolved a variety of kinematic, morphological, physiological, and behavioral adaptations for efficient locomotion to reduce energy expenditure while moving to find, capture, and consume ...

Satellite tracking of juvenile whale sharks in the Sulu and Bohol Seas, Philippines [PDF]

open access: yesPeerJ, 2018
The whale shark Rhincodon typus was uplisted to ‘Endangered’ in the 2016 IUCN Red List due to >50% population decline, largely caused by continued exploitation in the Indo-Pacific. Though the Philippines protected the whale shark in 1998, concerns remain

Lessons learned from screening potential other effective area‐based conservation measures

open access: yesConservation Biology, EarlyView.
Abstract Other effective area‐based conservation measures (OECMs) are sites that deliver effective biodiversity outcomes irrespective of their management objectives. These areas are widely expected to play an important role in efforts to protect 30% of Earth by 2030.

Effects of vessel traffic and ocean noise on gray whale stress hormones

open access: yesScientific Reports, 2022
Human use of marinescapes is rapidly increasing, especially in populated nearshore regions where recreational vessel traffic can be dense. Marine animals can have a physiological response to such elevated human activity that can impact individual health ...

Wanted Dead or Alive? The Relative Value of Reef Sharks as a Fishery and an Ecotourism Asset in Palau [PDF]

open access: yes, 2011
Over the last 20 years, ecotourism to view and interact with marine megafauna has become increasingly popular (Higham and Lück 2008). Examples of this type of tourism include turtle and whale watching, snorkelling with seals and shark diving (Jacobson ...

Threats to and management of Natura 2000 protected areas relative to agricultural practices

open access: yesConservation Biology, EarlyView.
Abstract The Natura 2000 (N2K) network combines biodiversity protection and socioeconomic targets. Human activities, such as agricultural practices, can affect biodiversity in N2K sites in diverse ways. Limiting activities with negative impacts while enforcing land management that supports biodiversity is crucial for effective conservation.
