Barbara Kus
Biography
Dr. Barbara Kus designs and conducts original field research on avian ecology and conservation to support science-based natural resource management in national and international contexts. Dr. Kus interacts closely with federal, state, and local resource managers and regulatory agencies to prioritize research needs, and design and conduct investigations to meet those needs. As a scientist broadly trained in ecology and evolutionary biology, she focuses her research on integrating management, which is typically short-term and threats-driven, with an evolutionary perspective that seeks longer-term sustainability of species and ecosystems through maintenance of evolutionary processes required for persistence. A theme of her research is that it is strategically long-term, yielding unique datasets that incorporate spatial and temporal patterns of response to environmental variability needed for this evolutionary perspective.

Population Structure and Demography of the Least Bell’s Vireo and Southwestern Willow Flycatcher and Use of Restored Riparian Habitat
Riparian woodlands are highly productive ecosystems that support a disproportionately high fraction of regional biodiversity. They are also one of the most endangered terrestrial systems in temperate North America, and have been reduced to just 5% of their former extent in California and throughout the American southwest. These losses have been accompanied by steep declines in numerous plant...
Distribution, Population Genetic Structure and Demography of Coastal Cactus Wrens in Southern California
Dr. Barbara Kus studies the demography and genetic structure of remaining populations of the coastal Cactus Wren to help managers develop strategies to increase the stability of wren populations.
Distribution, Occupancy and Population Genetic Structure of California Gnatcatchers in Southern California
The coastal California Gnatcatcher (Polioptila californica californica), a federally threatened species, is considered a flagship species for southern California conservation planning. Dr. Barbara Kus collaborates with Dr. Amy Vandergast and local agencies to provide information to managers that can be used to conserve this species and its habitat.
Monitoring Avian Productivity and Survivorship (MAPS)
Dr. Barbara Kus is a partner in an international bird-monitoring program to provide long-term data throughout North America. MAPS or “Monitoring Avian Productivity and Survivorship”, uses capture and banding data to compile basic demographic parameters of migratory species, many of which are imperiled regionally and even globally. Age- and sex-specific data on annual survival, reproduction,...

Lynn, Suellen; Madden, Melanie C.; Kus, Barbara E. Female-biased sex ratio, polygyny, and persistence in the endangered Southwestern Willow Flycatcher (Empidonax traillii extimus)
Demographic changes in populations, such as skewed sex ratios, are of concern to conservationists, especially in small populations in which stochastic and other events can produce declines leading to extirpation. We documented a decline in one of the few remaining populations of Southwestern Willow Flycatcher (Empidonax traillii extimus) in...
Kus, Barbara E.; Howell, Scarlett; Wood, Dustin A. Conservation genomics reveals multiple evolutionary units within Bell’s Vireo (Vireo bellii).
The Bell’s Vireo (Vireo bellii) is a widespread North American species of bird that has declined since the mid-1960s primarily due to habitat modification. Throughout its range, Bell’s Vireo populations are regulated under varying degrees of protection; however, the species has never been characterized genetically. Therefore, the...
Klicka, Luke B.; Kus, Barbara E.; Title, Pascal O.; Burns, Kevin J. Habitat fragmentation in coastal southern California disrupts genetic connectivity in the cactus wren (Campylorhynchus brunneicapillus)
Achieving long-term persistence of species in urbanized landscapes requires characterizing population genetic structure to understand and manage the effects of anthropogenic disturbance on connectivity. Urbanization over the past century in coastal southern California has caused both precipitous loss of coastal sage scrub habitat and declines in...
