Recent work on captive flying squirrels has demonstrated a novel degree of flexibility in the use of different orientation cues. In the present study, we examine to what extent this flexibility is present in a free-ranging population of another tree squirrel species, the fox squirrel. We trained squirrels to a rewarded location within a square array of four(More)
Fox squirrels have an impressive ability to remember the location of stored food. In doing so, they combine information from landmarks of different types. We define a Bayesian model that indicates how an ideal observer would optimally integrate landmark cues, and fit this model to the decisions made by squirrels in a spatial memory task. The resulting model(More)
Pretreatment with 1 nM 1,25-dihydroxyvitamin D(3) (1,25), or non-hypercalcemic Vitamin D analogs, upregulated the response of creatine kinase (CK) to 17beta-estradiol (30 nM E(2)), raloxifene (3000 nM RAL) or dihydrotestosterone (300 nM DHT) in primary human bone cells. Previously, we reported that these osteoblast-like cells responded to gonadal steroids(More)
