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).
Damage to the brain from a brain injury can result in physical, emotional, psychological and practical problems. Suddenly, one's whole life expectations may change.Career prospects, relationships with family and friends, personal goals and ambitions may change in an instant. brain injury or 'Traumatic Brain Injury' can be defined as 'damage to living brain tissue that is initially caused by external mechanical forces'. This contrasts with brain injury caused by internal events such as blood vessels bursting (strokes), growth of tumours, viruses or development of diseases.
