Evaluation of ALBA device for upper extremity motor function in adults with subacute and chronic acquired brain injury: a randomised controlled trial protocol in a tertiary clinic of the metropolitan region of Chile.

Introduction: Stroke is a significant worldwide cause of death and a prevalent contributor to long-term disability among adults. Survivors commonly encounter a wide array of motor, sensory and cognitive impairments. Rehabilitation interventions, mainly targeting the upper extremities, include a wide array of components, although the evidence indicates that the intensity of practice and task-specific training play crucial roles in facilitating effective results.

Correlates of bird collisions with buildings across three North American countries.

Collisions with buildings cause up to 1 billion bird fatalities annually in the United States and Canada. However, efforts to reduce collisions would benefit from studies conducted at large spatial scales across multiple study sites with standardized methods and consideration of species- and life-history-related variation and correlates of collisions. We addressed these research needs through coordinated collection of data on bird collisions with buildings at sites in the United States (35), Canada (3), and Mexico (2).

Determinants of seed removal distance by scatter-hoarding rodents in deciduous forests.

Scatter-hoarding rodents should space food caches to maximize cache recovery rate (to minimize loss to pilferers) relative to the energetic cost of carrying food items greater distances. Optimization models of cache spacing make two predictions. First, spacing of caches should be greater for food items with greater energy content.
