The evolution of plant ecosystems during the Cenophytic was complex and influenced by
both abiotic and biotic factors. Among abiotic forces were tectonics, the distribution of …

One of the most challenging fauna to study in situ is the obligate cave fauna because of the
difficulty of sampling. Cave-limited species display patchy and restricted distributions, but it …

Subglacial landscapes, revealed in regions of recent ice-sheet retreat, provide a window
into ice-sheet dynamics and interactions with evolving subglacial topography. Here, we …

Louisiana, USA, is among the most vulnerable areas globally to coastal natural hazards,
with risk vulnerability likely increasing. The risks associated with non-tropical-cyclone …

The Gray Fossil Site, northeastern Tennessee, is formed by multiple karst sub-basins filled
with lacustrine sediments. The oldest sediments found were recently dated as Paleo-Eocene …

Abstract Late Neogene floras of North America are mainly represented by sites located
along the east coast Piedmont and the Great Plains. To date, there are only two upper …

Screen-washing of unconsolidated fossiliferous sediments from the late Neogene Pipe
Creek Sinkhole (Grant County, Indiana) yielded two coprolites. Maximum preserved …

Paleoclimate reconstructions can provide a window into the environmental conditions in
Earth history when atmospheric carbon dioxide concentrations were higher than today. In …

Sinkholes (or dolines) are an often-overlooked environmental hazard. The processes that
lead to their formation are slow and insidious, which encourage a lack of awareness or …

The soils in the unglaciated part of Wisconsin have a loess cover over sedimentary rock,
mostly dolostone of Ordovician age. The dolostone has weathered and produced layers of …
