Estimating the spatial and temporal distribution of species richness within Sequoia and Kings Canyon National Parks. [PDF]
, 2014 Evidence for significant losses of species richness or biodiversity, even within protected natural areas, is mounting. Managers are increasingly being asked to monitor biodiversity, yet estimating biodiversity is often prohibitively expensive.

A hierarchical distance sampling model to estimate spatially explicit sea otter density
Ecosphere, 2021 Wildlife managers often rely on analyses conducted prior to the widespread adoption of hierarchical models which can lead to questions about the accuracy of previous inferences.

Intrapopulation differences in polar bear movement and step selection patterns
Movement Ecology, 2022 Background The spatial ecology of individuals often varies within a population or species. Identifying how individuals in different classes interact with their environment can lead to a better understanding of population responses to human activities 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 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.

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.
