Eating Some Invasive Species Could Help To Mitigate The Impacts Of Climate Change-Related Invasions, And May Increase Future Food Security, Jesse Bull Saffeir
Eating Some Invasive Species Could Help To Mitigate The Impacts Of Climate Change-Related Invasions, And May Increase Future Food Security, Jesse Bull Saffeir
Independent Study Project (ISP) Collection
Climate change is predicted to increase the spread and abundance of invasive species and to erode global food security. I hypothesized that by incorporating edible invasive species into local food sheds, these two problems could help to mitigate each other. I set out to answer two questions: could eating invasive species reduce their spread and abundance? And could eating invasive species minimize the impacts of climate-change related food shocks? To answer these questions, I surveyed the existing literature on human consumption of invasive species, created a list of criteria that make an invasive species suitable for management through human consumption, …
Shrimp Aquaculture In Aguadulce: Impacts On Mangrove Forest Health And Shrimp Larvae Populations In Two Sites On The Salado Coastline, Nick Jickling
Shrimp Aquaculture In Aguadulce: Impacts On Mangrove Forest Health And Shrimp Larvae Populations In Two Sites On The Salado Coastline, Nick Jickling
Independent Study Project (ISP) Collection
Shrimp aquaculture is an important industry in Republic of Panama, providing jobs and infrastructure, while supplying the country with seafood and export income. Aquaculture is accompanied by many negative impacts on mangrove ecosystems, and subsequently offshore marine stocks. The abundance and diversity of gastropods and shrimp were sampled in the Salado coastline of Aguadulce, Panama to evaluate the impacts of aquaculture disturbance on mangrove forests. Gastropods were sampled at 3 sites on 9, 100m transects in a “pristine” and disturbed forest. Shrimp were sampled using a push net in 24 sites in tide pools and abandoned shrimp ponds of the …
Nutrient Cycling In The Amazon: A Comparison Of Soil Characteristics, Insects, Root Types And Decomposition Rates Between Varzea And Terra Firme Habitats In The Ecuadorian Amazon, Mira Ensley-Field
Independent Study Project (ISP) Collection
Decomposition and nutrient cycling form the basis of every ecosystem. Nutrient availability in the soil affects plant species composition, richness, and productivity. The Amazon rainforest is known for its unusually fast nutrient cycle, but many aspects lack detailed study and analysis. This comparative study carried out in the Ecuadorian Amazon had four primary objectives related to understanding the nutrient cycle in the Amazon; 1.) analyze soil characteristics, 2.) assess insect diversity in the leaf litter layer, 3.) examine root characteristics, and 4.) measure the decomposition rate between Varzea and Terra Firme habitats alongside the Rio Napo. Forty 0.25 x 0.25m …
Effect Of Varied Disturbance Types On Dorylus (Anomma) Molestus Defensive Behavior In The West Usumbara Mountains, Tanzania., Ryan Mahar
Independent Study Project (ISP) Collection
The purpose of this study was to observe novel nest characteristics of Dorylus molestus (Siafu), as well as their defensive behavior in response to varied disturbance methods. The number of defensive soldiers at a specific section of a column was counted before and after each agitation. Varied agitation methods were used on columns without larvae presence to test how soldiers responded to different disturbance types. Disturbances on columns with larvae presence were compared to those on columns without larvae. Nest distribution, behavior, composition, and size were observed objectively. Mechanical disturbance was found to incite the greatest increase in defensive soldier …
Seagrass Community Change At Three High Risk Ports In The Great Barrier Reef World Heritage Area From 2005 To 2014, Celeste Venolia
Seagrass Community Change At Three High Risk Ports In The Great Barrier Reef World Heritage Area From 2005 To 2014, Celeste Venolia
Independent Study Project (ISP) Collection
Seagrass meadows are extremely valuable and dynamic ecosystems currently facing pressure from anthropogenic disturbances. Seagrass ecosystems are declining globally because of direct and indirect threats that shift environmental conditions controlling seagrass distribution. Seagrass species responses to disturbances vary based on a number of factors including life history strategy. The goal of this study was to map and analyze patterns of dominant seagrass species change at Cairns and Gladstone from 2005-2014 and Townsville from 2007-2014. This compilation data set was symbolized according to the life history strategy of the species. The major disturbances during this time period were physical damage from …
Comparing Avian Diversity And Anthropogenic Disturbance At Sendero Los Quetzales Cerro Punta, Panamá, Sloane Merdinger
Comparing Avian Diversity And Anthropogenic Disturbance At Sendero Los Quetzales Cerro Punta, Panamá, Sloane Merdinger
Independent Study Project (ISP) Collection
This report summarizes the survey of land and avian diversity along a transect that runs from the exterior to the interior of the Los Quetzales Trail of Parque Nacional Volcán Barú in Cerro Punta, Chiriquí, Panamá. The region of Cerro Punta is Panamá’s primary producer of produce and also home to one of the most biodiverse land reserves in the world. Despite protection efforts the area is continuously threatened by human development. The study juxtaposes calculated Shannon-Wiener Biodiversity Indices across graduated levels of anthropogenic disturbance to determine if there is a significant difference in biodiversity between areas with low, intermediate, …
