An Evaluation Of Soils On Sólheimajökull Glacier Foreland: Using Invertebrates And Decomposition As Bio-Indicators Of Soil Quality, Carolyn Weisman
An Evaluation Of Soils On Sólheimajökull Glacier Foreland: Using Invertebrates And Decomposition As Bio-Indicators Of Soil Quality, Carolyn Weisman
Independent Study Project (ISP) Collection
Anthropogenic climate change has led to the retreat of glaciers globally. As glaciers melt, they expose the underlying land- termed the glacier foreland. These forelands provide a natural laboratory for studying ecological succession after a massive disturbance, which is in this case glaciation. In this study, soil invertebrates and decomposition are used as bio-indicators of the soil quality in the foreland of Sólheimajökull Outlet Glacier. Soil cores were collected from five sites (A-E) located 300m apart moving away from the glacier terminus. The abundance of each observed invertebrate taxa and the dissolved oxygen (DO) levels were taken for 30 soil …
Incubation Under Climatewarming Affects Behavioral Lateralisation In Port Jackson Sharks, Catarina Vila Pouca, Connor Gervais, Joshua Reed, Culum Brown
Incubation Under Climatewarming Affects Behavioral Lateralisation In Port Jackson Sharks, Catarina Vila Pouca, Connor Gervais, Joshua Reed, Culum Brown
Culum Brown, PhD
Climate change is warming the world’s oceans at an unprecedented rate. Under predicted end-of-century temperatures, many teleosts show impaired development and altered critical behaviors, including behavioral lateralisation. Since laterality is an expression of brain functional asymmetries, changes in the strength and direction of lateralisation suggest that rapid climate warming might impact brain development and function. However, despite the implications for cognitive functions, the potential effects of elevated temperature in lateralisation of elasmobranch fishes are unknown. We incubated and reared Port Jackson sharks at current and projected end-of-century temperatures and measured preferential detour responses to left or right. Sharks incubated at …
Negative Impacts Of The Beef Industry: Lab-Grown Meat, Stephanie Grass
Negative Impacts Of The Beef Industry: Lab-Grown Meat, Stephanie Grass
WRIT: Journal of First-Year Writing
The beef industry is harmful to the environment and human health and alternative solutions must be implemented in order to mitigate the effects of climate change. Water and grain are used in agriculture in abundance despite the negative environmental effects it causes. Cattle are the biggest contributors to greenhouse gas emissions in the sector, also contributing to climate change. Antibiotics are used in large quantities without regard to potential future consequences. One potential solution for this problem is lab-grown beef, which demands very little from the consumer and would take pressure off the environmental issues the beef industry creates. Lab-grown …
Managing Urban Crow Populations In Japan, Tsuyoshi Yoda
Managing Urban Crow Populations In Japan, Tsuyoshi Yoda
Human–Wildlife Interactions
Crow (Corvus spp.) populations are increasing globally. This is cause for concern because overabundant crow populations can damage agricultural crops, harm native wildlife, and become a nuisance in urban areas. In Japan, the carrion (C. corone) and large-billed crow (C. macrorhynchos) can cause damage to crops and livestock. This damage is predicted to increase in Japan with climate change, especially when precipitation increases, inducing landscape changes that may favor crow populations and activities. In Japan, the primary control method used to manage crow damage is the destruction of nests by a crow control officer who …
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
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 Full-Text 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 …
