Does the timing of attainment of maturity influence sexual size dimorphism and adult sex ratio in turtles?
Jeffrey E. Lovich, J. Whitfield Gibbons, Mickey Agha
2014, Biological Journal of the Linnean Society (112) 142-149
The attainment of sexual maturity has been shown to affect measures of sexual size dimorphism (SSD) and adult sex ratios in several groups of vertebrates. Using data for turtles, we tested the model that sex ratios are expected to be male-biased when females are larger than males and female-biased when...

Animal reintroductions: an innovative assessment of survival
Erin L. Muths, Larissa L. Bailey, Mary Kay Watry
2014, Biological Conservation (172) 200-208
Quantitative evaluations of reintroductions are infrequent and assessments of milestones reached before a project is completed, or abandoned due to lack of funding, are rare. However, such assessments, which are promoted in adaptive management frameworks, are critical. Quantification can provide defensible estimates of biological success, such as the number of...
Population declines lead to replicate patterns of internal range structure at the tips of the distribution of the California red-legged frog (Rana draytonii)
Jonathan Q. Richmond, Adam R. Backlin, Patricia J. Tatarian, Ben G. Solvesky, Robert N. Fisher
2014, Biological Conservation (172) 128-137
Demographic declines and increased isolation of peripheral populations of the threatened California red-legged frog (Rana draytonii) have led to the formation of internal range boundaries at opposite ends of the species’ distribution. While the population genetics of the southern internal boundary has been studied in some detail, similar information is...

Preliminary interpretation of pre-2014 landslide deposits in the vicinity of Oso, Washington
Ralph A. Haugerud
2014, Open-File Report 2014-1065
High-resolution topographic surveys allow fairly precise mapping of landslide deposits and their relative ages. Relative ages are determined by cross-cutting relations and the amount of smoothing—more smoothed slide deposits are older—of these deposits. The Tulalip Tribes, in partnership with the Puget Sound Lidar Consortium, acquired a high-resolution lidar (light detection...
