Ontogeny of fear: Influence of corticosterone.
(2005)
A strong attachment to the caregiver is critical for survival in altricial species, including humans. While some behavioral aspects of attachment have been characterized, its neurobiology has only recently received attention. ...
Olfactory bulb coding and odor discrimination.
(2005)
Olfactory system second-order neurons, mitral-tufted cells, have odorant receptive fields (ORFs) (molecular receptive ranges in odorant space for carbon chain length in organic odorant molecules). This study quantified ...
Endocrine mediation of alternative mating tactics in toads: A proximate perspective on ecological patterns and sexual selection.
(2005)
Male Great Plains toads (Bufo cognatus) and Woodhouse's toads (Bufo woodhousii) alternate between one of two mating tactics; they may either vocalize to attract mates or they may adopt a non-calling "satellite" tactic. ...
Cambrian [Marjuman] trilobites (Arthropoda) of the Cow Head, western Newfoundland.
(2005)
Conglomerates consisting of shelf-derived limestone boulders in debris flows form the fossiliferous strata of the Cow Head Group on the west coast of Newfoundland. These conglomerates have yielded in excess of 20,000 ...
Cottonmouth (Agkistrodon piscivorus) spatial ecology.
(2005)
Radio-telemetry was used to study spatial ecology of a Cottonmouth (Agkistrodon piscivorus) population in eastern Texas. I examined effects of sex, reproductive state, and body size on spatial use within a riparian habitat. ...
Effects of fish density, identity, and species richness on stream ecosystems.
(2005)
Stream ecosystem properties and functions are important because they provide services such as water purification, oxygen production, and carbon fixation that help sustain life. Aquatic organisms can affect these properties ...
