Determining the dietary preferences and population genetics of an endangered bumble bee, Bombus affinis, by maximizing the use of museum specimens

Bombus affinis, the rusty patched bumble bee, was federally listed as an endangered species in 2017 and has been identified as one of the top priority species for recovery nationally. Shortly after listing the species, partnering researchers and FWS prioritized the research needed to prevent the extinction of B. affinis. Some of the top research needs that were identified...

Conservation Genetics and Genomics of the Narrowly Endemic Island Marble Butterfly Euchloe ausonides insulanus

The island marble butterfly (Euchloe ausonides insulanus) was first discovered on Vancouver Island, Canada in 1861.  Based on morphological characteristics, it has been described as a subspecies of Euchloe ausonides.  After a collection was made in 1908 on Gabriola Island, Canada, the island marble was not seen again until 1998 on San Juan Island, Washington, USA. Recent...

Genetic characterization of the clubshell species complex (Pleurobema clava and P. oviforme) for enhanced conservation

The diversity of freshwater mussels (family Unionidae) in the United States is unmatched in the rest of the world, yet this biodiversity is highly vulnerable, with more than 70% of recognized species considered to be either endangered, threatened, or of special concern.  Most species inhabit limited ranges and have small (and/or often unknown) dispersal abilities due to reliance on specific...

Development of Next Generation Techniques of fecal samples collected from nestling cactus wren

Coastal cactus wren populations have declined in southern California over the last three decades. In San Diego County, this decline has been especially noticeable in the Otay area, which in 2014 supported 14 territories on conserved lands. In the past, there were 25-53 active territories reported for this same area, with the highest estimate in 1992. There is also concern the number of active...

Developing and testing eDNA markers for the Federally endangered dwarf wedgemussel, Alasmidonta heterodon and other key freshwater mussel species

Dwarf wedgemussel is a federally endangered freshwater mussel with a historic range spanning the Atlantic coast. However, populations have dramatically declines over the last 30 years.  Therefore, knowledge of current population distribution and abundance is critical to resource managers in order to monitor the species over time and to guide recovery actions. Manual survey efforts (snorkel or...

Quantitative Framework to Model Risk of Collisions between Marine Wildlife and Boats

Collisons between wildlife and vehicles threaten many species, and can lead to human loss of life, injuries, and loss of property. USGS is developing models to help evaluate the effectiveness of wildlife protection zones and optimize the design of these protected areas.
