Environmental conditions and marine heatwaves influence blue whale foraging and reproductive effort. [PDF]

Ecol Evol, 2023
Our work links animal behavior and oceanography to provide insights into species life history and investigate the impacts of environmental change. We examine environmental correlates of blue whale vocalization patterns in Aotearoa New Zealand. Our results demonstrate the vulnerability of marine predator populations to marine heatwaves due to the links ...

Inversion of Rayleigh Wave Dispersion Curves via Long Short-Term Memory Combined with Particle Swarm Optimization. [PDF]

Comput Intell Neurosci, 2022
An essential step in surface wave exploration is the inversion of dispersion curves. By inverting dispersion curves, we can effectively establish the shear‐wave velocity model and obtain reliable subsurface stratigraphic information. The inversion of dispersion curves is an inversion problem with multiple parameters and multiple poles, and obtaining a ...

Vascularization of the gastrointestinal tract of the bottlenose dolphin (Tursiops truncatus, Montagu 1821). [PDF]

J Anat
Representative scheme of the gastrointestinal blood supply of the bottlenose dolphin. The duodenum is supplied by multiple duodenal arteries, the pacreaticoduodenal arteries do not supply the pancreas, and the caudal mesenteric artery can originate both from the cranial mesenteric artery or the aorta.

Histochemical indications for a chemically complex signal produced by the cervical gill slit gland of the pygmy sperm whale (Kogia breviceps). [PDF]

Anat Rec (Hoboken)
Abstract The pygmy sperm whale (Kogia breviceps) possesses an exocrine gland associated with its false gill slit pigmentation pattern. The cervical gill slit gland is a compound tubuloalveolar gland that produces a holocrine secretion and displays maturational changes in size and secretory histology. While the morphology of the cervical gill slit gland

Osteometric and Morphologic Study of Appendicular Skeletons of Female Simien Sheep in Wogera District, Northwest Ethiopia. [PDF]

Vet Med Sci
ABSTRACT Simien sheep are the predominant fat‐tailed sheep breeds found in Northwest Ethiopia, playing a significant role in the livelihood of resource‐poor farmers. This study provides the morphometric and morphological descriptions of the appendicular skeletons of Ethiopia's indigenous female Simien sheep.

Color pattern complexity in dwarf minke whales (Balaenoptera acutorostrata) of the northern Great Barrier Reef of Australia

Marine Mammal Science, Volume 39, Issue 3, Page 780-793, July 2023., 2023
Abstract Complex color patterning is a characteristic feature of dwarf minke whales (DMWs; Balaenoptera acutorostrata) which has been used to photographically identify (photo‐ID) individuals and to research an aggregation on Australia's Great Barrier Reef (GBR).

Evaluation of physiological stress in free‐ranging bears: current knowledge and future directions

Biological Reviews, Volume 98, Issue 1, Page 168-190, February 2023., 2023
ABSTRACT Stress responses, which are mediated by the neurogenic system (NS) and hypothalamic–pituitary–adrenal (HPA) axis help vertebrates maintain physiological homeostasis. Fight‐or‐flight responses are activated by the NS, which releases norepinephrine/noradrenaline and epinephrine/adrenaline in response to immediate stressors, whilst the HPA axis ...

Ionizing radiation and melanism in Chornobyl tree frogs

Evolutionary Applications, Volume 15, Issue 9, Page 1469-1479, September 2022., 2022
Abstract Human actions are altering ecosystems worldwide. Among human‐released pollutants, ionizing radiation arises as a rare but potentially devastating threat to natural systems. The Chornobyl accident (1986) represents the largest release of radioactive material to the environment. Our aim was to examine how exposure to radiation from the Chornobyl
