Abstract Migratory animals follow seasonal cycles comprising linked phases often with different habitat requirements and demographic processes.Conservation of migratory species therefore must consider the full seasonal cycle to identify points limiting population viability.For western monarch butterflies, which have experienced significant declines
Abstract Ambulation with existing prostheses is extremely difficult for individuals with bilateral above-knee amputations.Commonly prescribed prostheses are passive devices that cannot replace the biomechanical functions of the missing biological legs.As a result, most individuals with bilateral above-knee amputations can only walk for short distan
