Determining taphonomic controls and rates of decay in cave environments using microcosms
(Society for Sedimentary Geology, 2018-04-03)
Caves are important sites of fossil preservation, especially for Quaternary vertebrates. Taphonomic processes operating in caves are not well understood and have never been experimentally examined. This study focuses on ...
Effects of legacy metabolites from previous ecosystems on the environmental metabolomics of the brine of Lake Vida, East Antarctica
Lake Vida, located in a closed basin in the McMurdo Dry Valleys, East Antarctica, permanently encapsulates an interstitial anoxic, aphotic, cold (−13 °C), brine ecosystem within 27+ m of ice. Metabolically active, but ...
Evidence for trait-based dominance in occupancy among fossil taxa and the decoupling of macroecological and macroevolutionary success
(University of Chicago Press, 2018-03-21)
Biological systems provide examples of differential success among taxa, from ecosystems with a few dominant species (ecological success) to clades that possess far more species than sister-clades (macroevolutionary success). ...
The greatest hits of all time: the histories of dominant genera in the fossil record
(Paleontological Society, 2018-08-01)
Certain taxa are noticeably common within collections, widely distributed, and frequently long-lived. We have examined these dominant genera as compared to rarer genera, with a focus on their temporal histories. Using ...
Using Satellite Observations to Assess the Spatial Representativeness of the GLNPO Water Quality Monitoring Program
The U.S. EPA’s Great Lakes National Program Office (GLNPO) annual water quality survey (WQS) collects data at a relatively small number of stations in each lake. The survey was designed to measure conditions in the ...
Estimation of the width of the nearshore zone in Lake Michigan using eleven years of MODIS satellite imagery
The nearshore zone, that region of water directly influenced by its proximity to the coast, has received increasing attention in recent years. The extent of the nearshore zone has been defined by some constant descriptive ...
