Blooming Mountains Of Biodiversity: An Investigation Of Angiosperms On Cerro Mayordomo, Tungurahua, Ecuador, Ella Matsuda Apr 2018

Blooming Mountains Of Biodiversity: An Investigation Of Angiosperms On Cerro Mayordomo, Tungurahua, Ecuador, Ella Matsuda

Independent Study Project (ISP) Collection

Ecuador is one of the most biodiverse places on the planet, and many of the species in the region are found nowhere else in the world. The cloud forest is particularly diverse because the mountainous terrain isolates populations and changes in elevation create a wide variety of habitats. Cerro Mayordomo is a relatively unexplored mountain in the cloud forest of Tungurahua, Ecuador. It is known to have very high levels of endemism and several new species have been discovered there, but the biodiversity of angiosperms on the mountain has never been quantified. In this study, 5x5 m quadrants were established …

Ecological Succession On Neotropical Landslides: Comparing Successional Patterns Of Four Different Aged Landslides In The Cerro Candelaria Reserve, Nace Keifer Oct 2017

Ecological Succession On Neotropical Landslides: Comparing Successional Patterns Of Four Different Aged Landslides In The Cerro Candelaria Reserve, Nace Keifer

Independent Study Project (ISP) Collection

Abstract In an area that is vulnerable to frequent landslides due to steep montane slopes and heavy rain falls it is important to understand how the ecosystem regenerates after it has been disturbed. This study examined ecological succession patterns by comparing the vegetation on four different aged landslides and the unharmed forest within the Cerro Candelaria Reserve, located in a cloud forest ecosystem in central Ecuador. One meter soil profiles and 5x5 meter vegetation quadrats were used to observe and characterize the habitats on the four individual landslides and unharmed forest. At each location, soil color, texture, and structure were …

Carbon Sequestration In The Cloud Forest: A Comparative Evaluation Of Aboveground Biomass Carbon Stock Potential In The Río Guajalito Reserve, Elli Mapstone Oct 2017

Carbon Sequestration In The Cloud Forest: A Comparative Evaluation Of Aboveground Biomass Carbon Stock Potential In The Río Guajalito Reserve, Elli Mapstone

Independent Study Project (ISP) Collection

As carbon dioxide levels in the atmosphere continue to rise at a rapid rate, it is necessary to understand how forests can both contribute to CO2 levels but also stop them from rising. Carbon sequestration levels in tropical montane cloud forests are a relatively understudied topic. Gathering carbon stock levels is the first step necessary to start a REDD+ project. Carbon stock levels can be studied on a global, regional or local level. This study used the University of Oxford/ Global Ecosystems Monitoring Network (GEM) methodology to examine carbon sequestration levels of aboveground biomass, specifically ground litter, large branches …

Herpetoplogical Survey Across Three Distinct Habitats In Ankarana National Park: Long-Term Effects Of Past Land Use On Species Composition In And Around The Park, Julia Park Apr 2017

Herpetoplogical Survey Across Three Distinct Habitats In Ankarana National Park: Long-Term Effects Of Past Land Use On Species Composition In And Around The Park, Julia Park

Independent Study Project (ISP) Collection

Ankarana National Park is home to a diverse population of herpetofauna. In this study, three distinct habitats in and around Ankarana National Park were surveyed for herpetological diversity. These habitats were defined as the deciduous forest located within the “tsingy” limestone karst canyons, the dry deciduous forest outside of the canyons, within the borders of the park, and the anthropogenically affected forest outside of the park’s borders, which is subject to logging and fruit tree harvesting. A total of 27 species of herpetofauna – six amphibian and 21 reptile species were found over the course of twelve days of surveying …

The Importance Of Rivers In Protected Areas: Macroinvertebrate Sampling Reveals The Impact Of Humans And Highways On Water Quality, Marie-Claire Harrison Oct 2016

The Importance Of Rivers In Protected Areas: Macroinvertebrate Sampling Reveals The Impact Of Humans And Highways On Water Quality, Marie-Claire Harrison

Independent Study Project (ISP) Collection

The water quality and level of contamination of two rivers in a cloud forest ecosystem in the Mejía region of Ecuador, the Tupí River and the Pilatón River were assessed through benthic macroinvertebrate sampling at various sites along the rivers. Many different biological indices were then used to assess water quality at each site. Pollution in the form of grey water, black water, and petroleum negatively impacted the water quality of the both rivers as they pass through the town of La Esperie. Differences in river structure and size also played a role in determining the prevalence of certain benthic …

The Optimal Foraging Of Equus Burchelli At Enashiva Nature Refuge, Edward Haubenreiser Oct 2014

The Optimal Foraging Of Equus Burchelli At Enashiva Nature Refuge, Edward Haubenreiser

Independent Study Project (ISP) Collection

Within the country of Tanzania lies a vast ecosystem known as the Serengeti. This unique landscape, primarily of grasslands and woodlands, shapes the seasonal feeding habits of the abundant wildlife that call the area home. While these feeding habits on a large spatial scale are well understood, such behavior within a specie’s specific environment remains of interest. With the theory of optimal foraging in mind, which considers how animals should look for and select food (Green, 1990), I studied the foraging habits of resident Burchell’s zebra (Equus burchelli) by observing if they move and forage among distinct resource …

Going Green And Staying Sustainable: Community Based Tree-Planting Projects In Mongolia, Rachel Klassen Apr 2013

Going Green And Staying Sustainable: Community Based Tree-Planting Projects In Mongolia, Rachel Klassen

Independent Study Project (ISP) Collection

Community based tree planting projects are abundant in Mongolia and have become a popular form of social movement towards promoting a healthy environment. With so many different varieties of tree planting projects in Mongolia, it is necessary to evaluate how well the different forms of Community-based tree planting projects function. The first research question created to access said Community projects is, are Community based tree planting projects environmentally sustainable? And the second, are Community-based tree planting projects in Mongolia sustainable from an organizational standpoint? To answer these questions interviews, surveys and case studies were given in the three …

Agroforestry And Smallholder Farmers: Climate Change Adaptation Through Sustainable Land Use, Colin Mccabe Jan 2013

Agroforestry And Smallholder Farmers: Climate Change Adaptation Through Sustainable Land Use, Colin Mccabe

Capstone Collection

Agriculture in the developing world will be extremely hard hit by climate change, and smallholder farmers in Least Developed Countries (LDCs) are among the most vulnerable to its impacts. There is a range of agricultural adaptations to climate change, and each context demands a unique appraisal of impacts and adaptations based on specific geography, local climate variability and expected change, and social conditions. The term “climate-smart agriculture” (CSA) has come to embody a set of practices in crop and livestock cultivation that 1) reduce greenhouse gas emissions (climate change mitigation), 2) build resilience to the impacts of climate change for …
