Effect of food deprivation upon electrically elicited predation in the cat
(Elsevier, 1977-01)
The present experiment examined the effects of food deprivation upon predatory attack elicited by electrical stimulation of lateral hypothalamic sites in the cat. Latencies for attack initiation and for object contact were ...
Immunochemical studies on the metabolism of nitrosamines by ethanol-inducible cytochrome P-450
(Elsevier, 1985-04-30)
The ethanol-induced rabbit liver microsomal cytochrome P-450, P-450LM3a, has been shown previously to efficiently catalyze the demethylation of N-nitrosodimethylamine (NDMA) with a Km of 2.9 mM. Since the predominant Km ...
Predator Effects On An Assemblage Of Consumers Through Induced Changes In Consumer Foraging Behavior
(Wiley Periodicals, Inc.Ecological Society of America, 2000-07)
Multivariate statistical analysis of net diatom species distributions in the Southwestern Atlantic and Indian Ocean
(Springer-Verlag; Springer-Verlag GmbH & Co. KG, 1985-12)
Vertical net haul diatom assemblages from near South Georgia, and from between Africa and Antarctica, were examined and compared. Variation among South Georgia stations was examined by principal component, cluster and ...
Biodiversity simultaneously enhances the production and stability of community biomass, but the effects are independent
(Wiley Periodicals, Inc.Ecological Society of America, 2013-08)
Germinal development in the sporocysts and rediae of the digenetic trematodes
(Elsevier, 1954-03)
Integrative measures of consumption rates in salmon: expansion and application of a trace element approach
(Blackwell Science Ltd, 2004-10)
1. Establishing reliable estimates of consumption is necessary for understanding the physiology, bioenergetics and trophic relationships of organisms. For fish, the inability to measure consumption directly prevents a ...
‘Floral’ scent production by Puccinia rust fungi that mimic flowers
(Blackwell Science Ltd, 1998-09)
Thermal adjustments in cardiac and skeletal muscles of lizards
(Springer-Verlag, 1969-03)
1. Isometric twitch tension development was measured over a wide range of temperatures in skeletal and cardiac (ventricular) muscles from diverse Australian lizards representing several families and including both diurnal ...
Appetitive determinants of self-stimulation
(Elsevier, 1978-08)
Previous reports have pointed to a biologically meaningful relationship between brain-stimulated reward and appetitive motivation such as feeding. The present experiments further examined this relationship in chronically ...
