Surveys for greater prairie-chickens (Tympanuchus cupido pinnatus) were conducted during April and May of 2010. We located 152 booming grounds where males gather for breeding displays, and we counted 1,499 male prairie-chickens, including birds of unknown sex.

In late summer and fall 1997, Aedes albopictus mosquitoes were found in Peoria, Illinois, a long recognized focus of La Crosse virus transmission. Larvae were found in tires and other artificial containers, biting adults were recovered, and eggs were collected in oviposition traps within a 25-ha area. One chipmunk trapped < 0.25 km from the infested area tested positive for neutralizing antibod...

BACKGROUND Climacteric skin aging affects certain biophysical characteristics of facial skin. The purpose of the present study was to assess the symmetric involvement of the cheeks in this stage of the aging process. METHODS Skin viscoelasticity was compared on both cheeks in premenopausal and post-menopausal women with indoor occupational activities somewhat limiting the influence of chronic...

CITATION: Excessive self grooming in mice has been used as a model for obsessive compulsive disorder. The fact that the prairie voles do this as consoling behaviour does suggest grooming is comforting. But it also seems that in some strains of mice, but not all, barbering is thought to be a sign of dominance and/or aggression. How can you differentiate between a potentially comforting behaviour...

Dogs are graced with large upper labial and buccal surfaces which facilitate closure of moderate sized defects. Cats, with their more refined facial conformation, lack the fullness and elasticity of the canine lips and cheeks. While dogs generally present with the greater number of wounds and oral neoplasms of the lips and cheeks, the following techniques employed by the author are equally appl...

By use of simplified technique and constant environmental conditions, I have demonstrated the existence in the chipmunk of a yearly clock. In a blinded chipmunk the clock manifested itself by remarkably consistent changes in running activity, food and water intake, and body weight over 6 1/2 yr. Studies on freshly trapped chipmunks kept in the same laboratory environment but with alternating li...
