Laura Snell: Studying the wild horses of northeastern California

On the Robustness of the Snell Envelope

We analyze the robustness properties of the Snell envelope backward evolution equation for the discrete time optimal stopping problem. We consider a series of approximation schemes, including cut-off type approximations, Euler discretization schemes, interpolation models, quantization tree models, and the Stochastic Mesh method of Broadie-Glasserman. In each situation, we provide non asymptotic...

Abundances of Small Mammals in Fir Forests in Northeastern California

We compared abundances of seven species of forest rodents among three types of fir (Abies concolor and A. magnifica) forest: unlogged old-growth, unlogged mature, and shelterwood-logged old-growth. Small mammals were livetrapped during summers 1991 and 1992 in four grids within each type of forest; grids were located in the Lassen National Forest in northeastern California. Shelterwood-logged f...

The Current Status of Wild Animal Rabies in California

Laura Carruth

LH: Tell me more about your work with teachers. LC: I run a week-long professional development workshop for K–12 teachers called “Why They Do What They Do at the Zoo: Animal Behavior and the Brain.” Also, I facilitate a summer neuroscience-themed camp for middle school-aged children. Both are sponsored by the Center for Behavioral Neuroscience. These projects have also received support from the...

Characterisation of phenolic compounds in wild fruits from Northeastern Portugal.

This study aimed to analyse the phenolic composition of wild fruits of Arbutus unedo (strawberry-tree), Prunus spinosa (blackthorn), Rosa canina and Rosa micrantha (wild roses). Analyses were performed by HPLC-DAD-ESI/MS. P spinosa fruits presented the highest concentration in phenolic acids (29.78 mg/100 g dry weight), being 3-O-caffeoylquinic acid the most abundant one, and flavone/ols (57.48...
