2021, Conference Paper, From the Eastern Piedmont to the Coastal Plain: a cross section through the Richmond Area Fall Zone: Guidebook for 2021 Virginia Geologic Field Conference
Introduction Although the Petersburg Granite had long been in practical use as a building stone since the 1830s (Watson, 1906; 1907; 1910; Darton, 1911; Steidtmann, 1945), it was first formally defined as a geologic unit by Anna Jonas on the 1928 geologic map of Virginia. Anna Jonas defined this unit...

A statistical framework to track temporal dependence of chlorophyll–nutrient relationships with implications for lake eutrophication management
Qianlinglin Qiu, Zhongyao Liang, Yaoyang Xu, Shin-Ichiro S. Matsuzaki, Kazuhiro Komatsu, Tyler Wagner
2021, Journal of Hydrology (603)
A reliable chlorophyll–nutrient relationship (CNR) is essential for lake eutrophication management. Although the spatial variability of CNRs has been extensively explored, temporal variations of CNRs at the individual lake scale has rarely been discussed. The paucity of information about temporal dependence in CNRs may in part be due to the...

Ontogenetic shifts from social to experiential learning drive avian migration timing
Briana Abrahms, Claire S. Teitelbaum, Thomas Mueller, Sarah J. Converse
2021, Nature Communications (12)
Migrating animals may benefit from social or experiential learning, yet whether and how these learning processes interact or change over time to produce observed migration patterns remains unexplored. Using 16 years of satellite-tracking data from 105 reintroduced whooping cranes, we reveal an interplay between social and experiential learning in migration...
