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).
Emotional and behavioral changes are a common effect of stroke. Not only can stroke impact one's mood and outlook, but the area of the brain injury and chemical changes may have significant effects on the brain. The brain is an extremely complex organ that controls various body functions. If a stroke occurs and blood flow can't reach the region that controls a particular body function, that part of the body won't work as it should. If the stroke occurs toward the back of the brain, for instance, it's likely that some disability involving vision will result.
