Ring-necked Pheasant brood habitat selection and movements in an intensive agricultural landscape
Alixandra Godar, Adela Piernicky, David A. Haukos, Jeff Prendergast
2023, Prairie Naturalist (55) 107-123
Management of row crops can greatly influence wildlife populations in an agriculturally intensive landscape. Many upland gamebird populations, including Phasianus colchicus L. (Ringnecked Pheasant; hereafter pheasant) are experiencing contemporary population declines in such landscapes throughout the Midwest United States. Reduced availability of quality brood habitat may be a factor in these declines....

2023, Herpetological Review (54) 648-649
Nest site selection is an important determinant of clutch success and hatchling sex ratios in Gopherus agassizii, Mojave Desert tortoises (Spotila et al. 1994. Herpetol. Monogr. 8:103-116). G. agassizii lay eggs in or near the entrance of their burrows (Ennen et al. 2012. Copeia 2012:222-228) and females of both G....
Leveraging angler effort to inform fisheries management: Using harvest and harvest rate to estimate abundance of White Sturgeon
Marta Ulaski, Joshua McCormick, Michael Quist, Zachary Jackson
2023, Journal of Fish and Wildlife Management (14) 324-336
Traditional methods for estimating abundance of fish populations are not feasible in some systems due to complex population structure and constraints on sampling effort. Lincoln’s estimator provides a technique that uses harvest and harvest rate to estimate abundance. Using angler catch data allows assumptions of the estimator to be addressed...
Evidence of a load-lightening helper effect in Florida Scrub-Jays: Implications for translocation
Alexis Cardas, Erin Hewett Ragheb, Karl E. Miller, Abby Powell
2023, Article
The Florida Scrub-Jay (Aphelocoma coerulescens) is an imperiled cooperatively breeding species endemic to Florida scrub habitats. Translocation of non-reproductive helpers has been proposed as a conservation tool to increase population size and connectivity. However, the potential consequences of helper removal on the source population remain unclear because the benefits provided...

An inventory of three-dimensional geologic models—U.S. Geological Survey, 2004–22
Donald S. Sweetkind, Kristine L. Zellman
2023, Data Report 1183
A database of spatial footprints and characteristics of three-dimensional geological models that were constructed by the U.S. Geological Survey between 2004 and 2022 was compiled as part of ongoing development of subsurface geologic information by the USGS National Cooperative Geologic Mapping Program. This initial inventory resulted in the compilation of...

This chapter provides an introduction to crater-size frequency distribution (CSFD) measurements and presents a review of the work performed on dating lunar geological units using CSFDs since the last New Views of the Moon volume (2006), including various volcanic and tectonic features, as well as individual impact craters. At the...
Hidden system identification: Basin modeling as a tool for examining sedimentary geothermal resource potential
Rand Gardner, Justin E. Birdwell
2023, Conference Paper, Using the Earth to save the Earth
Three-dimensional (3D) geologic and temperature models have been developed for the onshore U.S. Gulf Coast. The results from these models identify areas of moderate- to high-temperature (90°-150°C and >150°C; respectively) geothermal resources at depths <6 km. This modeling study addresses the fundamental challenge of predicting where opportune temperature and lithology...
