Cahokia's origins: Religion, complexity and ridge-top mortuaries in the Mississippi River Valley
… of the city of Cahokia through an exploration of ridge-top mortuary practices across the three precincts of Cahokia, East St. Louis and St. Louis ca. AD 1050-1200. Through the theoretical lens of relational ontology and ‘New Animism’ I investigate how Cahokia’s emergence was intrinsically tied to …

Population genetics of wood frogs (Lithobates sylvaticus) in a forested ridge-top wetland ecosystem
… how land-use changes impact biodiversity. Ridge-top wetlands are unique habitat for pond-breeding amphibians and the Daniel Boone National Forest (DBNF) contains natural forested ridge-top wetlands in close proximity to constructed wetlands intermixed across the same landscape. Genetic data …

Amphibian Community Composition And Disease Susceptibility In Ridge-Top Wetlands Of The Daniel Boone National Forest
… wetlands are a natural feature of the ridge-top ecosystem in the Daniel Boone National Forest (DBNF) in eastern Kentucky, and support a diverse amphibian assemblage characterized by species with short larval periods. However, hundreds of hydrologically permanent ponds have been …

Interactions between Eastern Newts and Wood Frogs in an anthropogenically altered wetland system in eastern Kentucky
<p>A key characteristic of the ridge-top ecosystem in eastern Kentucky is the presence of ephemeral wetlands. Ephemeral wetlands of the ridge-top ecosystem support an amphibian community assemblage characterized by species with short larval periods (e.g., Wood Frogs [<em>Lithobates sylvaticus<em>] …

An environmental history : William Cameron Park, Waco, Texas.
… of this project suggest first that the park's ridge-top was completely cleared for grazing during the late 1800s and early 1900s and secondly that release of the pastures led to differential regeneration of forest cover, first in Juniperus species and then with deciduous species. This release …

Efficacy Of Constructed Wetlands Of Various Depths For Natural Amphibian Community Conservation
… whether or not constructed wetlands located on ridge tops in eastern Kentucky in the Daniel Boone National Forest (DBNF) had amphibian communities comparable to natural ephemeral wetlands, 2) to examine amphibian predator-prey relationships within the constructed wetlands, and 3) to determine …

Revisiting Aldo Leopold's "Perfect" Land Health: Conservation and Development in Mexico's Rio Gavilan
… erosion, service sector economics, and (at some ridge-top sites) forest density are the land health indicators in worst condition. Land health restoration projects are feasible.

Validation Of Kentucky Wetlands Rapid Assessment Method (ky-Wram) Metrics Using Macroinvertebrate Communities Of Forested Depressional Wetlands
… scores. Nineteen naturally forested, isolated, ridge-top, ephemeral wetlands were selected in the Daniel Boone National Forest for study. Macroinvertebrates were collected conducting 1-meter sweeps with a D-frame dipnet every 5 meters in the emergent vegetation zone around the perimeter of the …

Amphibian and plant communities of natural and constructed upland-embedded wetlands in the Daniel Boone National Forest
… (DBNF), numerous UEWs have been constructed on ridge-tops to benefit game and bat species. Previous studies have shown that many of these constructed wetlands have permanent hydroperiods and different amphibian communities than co-occurring natural ephemeral wetlands. Wood frog and marbled …
