Indirect biotic effects arising from multispecies interactions can alter the structure and function of ecological communities--often in surprising ways that can vary in direction and magnitude. On Pacific coral reefs, predation by the crown-of-thorns sea star, Acanthaster planci, is associated with broad-scale losses of coral cover and increases of macroalgal cover. Macroalgal blooms increase c...

The piriform cortex (PC), like other cortical regions, normally operates in a state of dynamic equilibrium between excitation and inhibition. Here we examined the roles played by pre- and postsynaptic GABAB receptors in maintaining this equilibrium in the PC. Using whole-cell recordings in brain slices from the anterior PC of mice, we found that synaptic activation of postsynaptic GABAB recepto...

Family and Gang as Agents of Socialization The family, conceived primarily as a child-rearing agency, and the gang, defined in some detail in the last chapter, were both prevalent forms of associational units in Midcity. It is important to repeat at this point that the term “family” as used in the present work refers to that kinship-based associational unit which bears primary responsibility fo...

Gonadal hormones are known to broadly influence cortical information processing. Findings from this study in rats suggest that for androgens, this influence may include stimulation of underlying corticocortical connections. First, immunoreactivity for intracellular androgen receptors, while present in all regions and layers examined, was found to be particularly abundant in sensory and motor re...

social capital has received considerable attention in all branches of social sciences, and has recently been the focus in the field to explain about procreator elements. trust is one of the social capital elements and plays an important role in specifying consequences incidental to social capital. nearly two decades ago, robert putnam proposed an explanation of trust relying on associational li...
