The Mammals of Angola [PDF]

open access: yes, 2019
Scientific investigations on the mammals of Angola started over 150 years ago, but information remains scarce and scattered, with only one recent published account. Here we provide a synthesis of the mammals of Angola based on a thorough survey of primary and grey literature, as well as recent unpublished records.

Coloration in Mammals

open access: yesTrends in Ecology & Evolution, 2020
Mammalian colors and color patterns are some of the most diverse and conspicuous traits found in nature and have been widely studied from genetic/developmental and evolutionary perspectives. In this review we first discuss the proximate causes underlying variation in pigment type (i.e., color) and pigment distribution (i.e., color pattern) and ...

The influence of anaesthesia with isoflurane on the pulmonary and aortic blood flow of Racing Pigeons (Columba livia f. domestica) measured by pulsed wave Doppler echocardiography [PDF]

open access: yesOpen Veterinary Journal, 2019
Doppler echocardiographic examinations are an important technique for evaluating the blood flow also in avian cardiology. The influence of anaesthesia on the blood flow in the heart is in detail unknown for most avian species.

Hunting by the Stroke: How Foraging Drives Diving Behavior and Locomotion of East-Greenland Narwhals (Monodon monoceros)

open access: yesFrontiers in Marine Science, 2021
Deep diving air-breathing species by necessity must balance submergence time and level of exercise during breath-holding: a low activity level preserves oxygen stores and allows longer duration submergence whereas high activity levels consume oxygen ...

Color Flow Doppler Echocardiography in Healthy Racing Pigeons (Columba livia f. domestica) and the Evidence of Physiological Blood Flow Vortex Formations

open access: yesVeterinary Sciences, 2020
In avian medicine, Doppler sonographic techniques are used to visualize and estimate blood flow in the heart. In the literature there is a lack of standardized studies of the use of color Doppler flow on healthy avian species.

Application of Felid Hair for Non-Invasive Tracking of Animal Reproductive Status and Adrenal Activity

open access: yesAnimals, 2022
Hair can be a useful matrix to examine the hormonal status of an animal, although it is difficult to correlate the results to a specific time point. The aim of this study was to evaluate seasonal changes in cortisol and testosterone levels in the hair of

Age‐associated variation in the gut microbiota of chinstrap penguins (Pygoscelis antarctica) reveals differences in food metabolism

open access: yesMicrobiologyOpen, 2021
Age is known to affect the gut microbiota in various animals; however, this relationship is poorly understood in seabirds. We investigated the temporal succession of gut microbiota in captive chinstrap penguins of different ages using high‐throughput ...
