Identifying and modeling patterns of tetrapod vertebrate mortality rates in the Gulf of Mexico oil spill [PDF]
Aquatic Toxicology Volume 105, Issues 1-2, September 2011, Pages
177-179, 2011 The accidental oil spill in the Gulf of Mexico in 2010 has caused perceptible damage to marine and freshwater ecosystems. The large quantity of oil leaking at a constant rate and the long duration of the event caused an exponentially increasing mortality

Trends 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 ...

Veterinary 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.

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 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.

Evidence of strong stabilizing effects on the evolution of boreoeutherian (Mammalia) dental proportions. [PDF]
, 2019 The dentition is an extremely important organ in mammals with variation in timing and sequence of eruption, crown morphology, and tooth size enabling a range of behavioral, dietary, and functional adaptations across the class.
