Inbreeding depression, or the reduced fitness of offspring of related parents, can cause the rapid decline and extinction of threatened populations in the wild. Gene flow can counteract drift and inbreeding by introducing genetic variation, but its effects depend on differences (demographic, ecological, and/or genetic) between source and recipient populations. As habitat fragmentation and population decline accelerate, it is critical that we understand how inbreeding and gene flow interact in nature to shape fitness and, ultimately, evolutionary outcomes. I will present preliminary results exploring the consequences of immigration to inbreeding (runs of homozygosity), levels of deleterious genetic load, and fitness in a pedigreed wild population of Florida Scrub-Jays (Aphelocoma coerulescens).
