Living under the scope: behavior affects survival in a heavily harvested and long‐lived ungulate

open access: yesWildlife Biology, EarlyView.
The spatiotemporal behavior of game species may play a critical role in their survival throughout the hunting season. Where humans are the most dominant predators, avoidance of landscape features that allow hunter access to hunting grounds can be key to increasing survival.

Assessing the utility of autonomous recording units and spring point counts for monitoring abundance of ruffed grouse Bonasa umbellus

open access: yesWildlife Biology, EarlyView.
The ruffed grouse Bonasa umbellus is a species of conservation concern that has declined across most of its range. At the southeastern trailing edge of the range in Georgia, grouse are restricted to elevations 600 m a.s.l. and abundance is relatively low.

Complex centers of polynomial differential equations

open access: yesElectronic Journal of Differential Equations, 2007
We present some results on the existence and nonexistence of centers for polynomial first order ordinary differential equations with complex coefficients.

Estimating red deer Cervus elaphus population density using drones in a steep and rugged terrain

open access: yesWildlife Biology, EarlyView.
Precise and accurate information about population density, crucial for wildlife management, is difficult to obtain for elusive species living in dense forests or steep and inaccessible terrain. Using unmanned aerial vehicles (UAVs), we developed a method for obtaining absolute population estimates of ungulates living in steep, rugged, and partly ...

Heating up parasitoid–host interactions: High temperature increased mortality of late‐instar braconid larvae and reduced ladybird recovery rate

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract With ongoing climate change, temperature‐dependent outcomes of host–parasitoid interactions can affect ecosystem functioning and key ecosystem services such as biological control. However, most studies addressing the impacts of temperature on host–parasitoid systems are

Seasonal body mass dynamics mediate life‐history trade‐offs in a hibernating mammal

open access: yesJournal of Animal Ecology, EarlyView.
We tested a suite of ecological hypotheses to explain variation in seasonal body mass dynamics of a fat‐storing mammalian hibernator. We further demonstrated that pre‐hibernation mass gain in ground squirrels mediates an annual allocation trade‐off between current and future reproduction as the squirrels forage and rear young under predation risk ...

A matrix generalization of a theorem of Fine

open access: yes, 2018
In 1947 Nathan Fine gave a beautiful product for the number of binomial coefficients $\binom{n}{m}$, for $m$ in the range $0 \leq m \leq n$, that are not divisible by $p$.

Monogenic Polynomials of Four Variables with Binomial Expansion [PDF]

open access: yes, 2014
In the recent past one of the main concern of research in the field of Hypercomplex Function Theory in Clifford Algebras was the development of a variety of new tools for a deeper understanding about its true elementary roots in the Function Theory of one Complex Variable.
