Summary

Fragmentation and loss of natural habitat have important consequences for wild populations and can negatively affect long-term viability and resilience to environmental change. Salt marsh obligate species, such as those that occupy the San Francisco Bay Estuary in western North America, occupy already impaired habitats as result of human development and modifications and are highly susceptible to increased habitat loss and fragmentation due to global climate change. We examined the genetic variation of the California Ridgway’s rail ( Rallus obsoletus obsoletus), a state and federally endangered species that occurs within the fragmented salt marsh of the San Francisco Bay Estuary. We genotyped 107 rails across 11 microsatellite loci [...]

Purpose

We sampled a representative number of California rail populations throughout the San Francisco Bay region and combined microsatellite genotyping analyses to: (1) assess the occurrence of genetic differentiation among saltmarsh fragments currently occupied by the California rail, and (2) measure demographic connectivity by inferring patterns of historical and contemporary gene flow.
