The creation of nature reserves is the primary means used by conservation biologists protect biodiversity. However, unless key ecological processes are protected within the reserves, it may be difficult to maintain biodiversity over the long-term.Consumption of woody vegetation by large herbivores such as moose and deer is one such key ecological process.he striking effects of moose browsing activity on Viburnum alnifolium and Abies balsamea has led to greater interest in the effect of this herbivore on community dynamics. Two additional grant proposals have been submitted (one funded, one not funded) that have built upon this critical ecological process.
Behavior and social problems also can be an indirect result of a brain injury. DifÂ­ficulties in paying attention, staying on task, and predicting the consequences of actions may be associated with behavior problems when caregivers expect preinjury levels of performance (Ylvisaker et al., 1998).
The behavioral effects of alcohol are produced through its actions on the central nervous system (CNS) and, in particular, the brain. Synaptic transmissionâthe process by which neurons in the CNS communicate with one anotherâis a particular target for alcohol actions that alter behavior.eurons are the cells within the brain that are responsible for rapid communication of information. Although similar to other cells in the body, neurons are specialized in ways that set them apart from other cells and endow them with the properties that allow them to carry out their unique role in the nervous system.
