From the Vagile to the Sedentary: Disease Implications and New Host Relationships on Islands

摘要: How species come to be established on islands and their consequent adaptations evolution are subjects that lie at the heart of much ecology evolutionary conservation biology. On islands, small populations, limited gene diversity flow, simpler ecosystems facilitate our understanding how arrive then adapt evolve in new locations. One component this is transition from arrival establishment may affect parasites diseases. Colonizing without full burdens weighing source allowing them reduce energetic investments immune defenses. However, reduced genetic also populations through inbreeding depression or diminish capacity evolve. Loss genes adaptation novel environments over time insular deal with old ones “catch up.” With increasing anthropogenic introduction biotas, including parasites, biodiversity becomes increasingly challenging, which turn reduces ability study understand both
