Rapidly Changing Tachyarrhythmia in Acute Stroke

Introduction: we report a 56-year-olds female with supraventricular arrhythmia due acute ischemic stroke without structural heart disease. Case Description: A patient presented with sudden onset of lethargy, right hemiplegia, and global aphasia. There was previous history of stroke 1 year ago presented with left hemiplegia that recovered completely during 10 days. There was no history of comorb...

The role of life history traits in mammalian invasion success

Why some organisms become invasive when introduced into novel regions while others fail to even establish is a fundamental question in ecology. Barriers to success are expected to filter species at each stage along the invasion pathway. No study to date, however, has investigated how species traits associate with success from introduction to spread at a large spatial scale in any group. Using t...

Plant fitness in a rapidly changing world.

Modern reliance on fossil fuels has ushered in extreme temperatures globally and abnormal precipitation patterns in many regions. Although the climate is changing rapidly, other agents of natural selection such as photoperiod remain constant. This decoupling of previously reliable environmental cues shifts adaptive landscapes, favors novel suites of traits and likely increases the extinction ri...
