Microgrid Technology And The Arctic: Green Renewable Technology Does Relate To The Land, Gerry Dell Aug 2019

Microgrid Technology And The Arctic: Green Renewable Technology Does Relate To The Land, Gerry Dell

Head and Heart Posters 2019

Microgrids can take power from other energy sources and share their loads meaning there is a less reliance on diesel power generation. Wind mill power generators, solar power (for the summer) and battery storage are fantastic elements for providing consistent power in the Arctic. These power systems have been tried and proven, in all conditions, over many years. Geothermal is another green efficient way to heat homes and businesses in the Arctic. When I worked for Dome Petroleum in McKinley Bay NWT, I was fortunate to work in the most extreme winter weather the Arctic can produce. With global warming …


Is Grassfed Meat And Dairy Better For Human And Environmental Health?, Frederick D. Provenza, Scott L. Kronberg, Pablo Gregorini Mar 2019

Is Grassfed Meat And Dairy Better For Human And Environmental Health?, Frederick D. Provenza, Scott L. Kronberg, Pablo Gregorini

Wildland Resources Faculty Publications

The health of livestock, humans, and environments is tied to plant diversity—and associated phytochemical richness—across landscapes. Health is enhanced when livestock forage on phytochemically rich landscapes, is reduced when livestock forage on simple mixture or monoculture pastures or consume high-grain rations in feedlots, and is greatly reduced for people who eat highly processed diets. Circumstantial evidence supports the hypothesis that phytochemical richness of herbivore diets enhances biochemical richness of meat and dairy, which is linked with human and environmental health. Among many roles they play in health, phytochemicals in herbivore diets protect meat and dairy from protein oxidation and lipid …


A Multi-Scale Analysis Of Jaguar (Panthera Onca) And Puma (Puma Concolor) Habitat Selection And Conservation In The Narrowest Section Of Panama., Kimberly A. Craighead Jan 2019

A Multi-Scale Analysis Of Jaguar (Panthera Onca) And Puma (Puma Concolor) Habitat Selection And Conservation In The Narrowest Section Of Panama., Kimberly A. Craighead

Antioch University Dissertations & Theses

Over the past two centuries, large terrestrial carnivores have suffered extreme population declines and range contractions resulting from the synergistic anthropogenic threats of land-use change and indirect effects of climate change. In Panama, rapid land use conversion coupled with climate change is predicted to negatively impact jaguar (Panthera onca) and puma (Puma concolor). This dissertation examined the environmental variables and scales influencing jaguar and puma habitat selection by season (annual, wet, and dry), using multi-scale optimized habitat suitability models and a machine-learning algorithm (Random Forests), in the narrowest section of Panama. The models derived from the data of an intensive …


Alpine Plant Communities Of The White Mountains Of New Hampshire: Aboveground Plant Diversity And Abundance Correlated To Belowground Factors, Timothy Maddalena-Lucey Jan 2019

Alpine Plant Communities Of The White Mountains Of New Hampshire: Aboveground Plant Diversity And Abundance Correlated To Belowground Factors, Timothy Maddalena-Lucey

Antioch University Dissertations & Theses

Alpine plant communities are fragile complex systems that may be threatened by climate change. Patterns of climate-driven soil warming are shown to have lasting effects on ecosystem nutrient cycles, alpine plant phenology, and belowground soil biotic activity. There are concerns in the alpine mycorrhizal research community as to how belowground fungal biomass will react to climate-driven soil warming. To address these concerns I asked in this study what are the correlations between belowground factors such as collective ectomycorrhizal (EcM) and ericoid mycorrhizal (ErM) percent colonization, pH, and soil depth to bedrock and aboveground plant diversity and richness. In 2018, on …
