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 types and degrees of disability that follow a stroke will depend upon which area of the brain is damaged. Stroke damage in the brain can affect the entire body, resulting in mild to severe disabilities. Specific effects of a stroke can include: Weakness (hemiparesis) or paralysis (hemiplegia) on one side of the body that may affect the whole side or just the arm or leg. The weakness or paralysis is on the side of the body opposite the side of the brain that was affected by the stroke. Spasticity, stiffness in muscles, painful muscle spasms.
