Treatments Of Cyanobacteria On Mariculture Sponges In Jambiani, Tanzania, Sally Thornton-White Oct 2022

Treatments Of Cyanobacteria On Mariculture Sponges In Jambiani, Tanzania, Sally Thornton-White

Independent Study Project (ISP) Collection

Since 2009, Marine Cultures, an NGO, has explored sponge farming in Jambiani to develop secure and sustainable livelihoods for the community. While sponge farming provides economic opportunity for an industry that functions within ecological boundaries, it faces unique issues that threaten its success. As climate change increases global water temperatures, cyanobacteria are causing increased death rates among mariculture sponges. Mitigating these negative effects with sustainable and reliable solutions can help Marine Cultures grow their positive impact. Alternative methods for mitigating cyanobacteria growth were tested during three study phases. Phase 1 tested how sponge health and algae growth responds to being …


Aman Iman: Resilient Customs, Community Water Management, And Dry Futures In Anounizme, Morocco, Haley Kirtland Oct 2022

Aman Iman: Resilient Customs, Community Water Management, And Dry Futures In Anounizme, Morocco, Haley Kirtland

Independent Study Project (ISP) Collection

This project explores how Anounizme, a village in southeastern Morocco, interacts with water. I was particularly curious about how traditional community management systems operate in the context of drought. I argue that the customary management system exhibits resiliency like it has in the face of Arabization, colonization, exploitative industry, and land privatization. It is capable of adapting to drought because it is more than a management system; it is a part of culture engrained as custom. Customs have porous boundaries, allowing a space for old aspects of culture to interact with both emerging aspects of culture and external pressures. I …


Creating Sustainable Biofuels Using Essential Oil Distillery Leaf Waste Near Vohimana Reserve, Ashley Cohen Oct 2022

Creating Sustainable Biofuels Using Essential Oil Distillery Leaf Waste Near Vohimana Reserve, Ashley Cohen

Independent Study Project (ISP) Collection

Like most of Madagasacar’s population, people around Vohimana Reserve rely on traditional fuels like firewood and charcoal for cooking and heating. As a result, the region is facing deforestation, which poses a threat to biodiversity and the livelihoods of local populations. A local essential oil distillery was created by the NGO L’Homme et L’Environnement as a sustainable income generator to combat deforestation and protect biodiversity. The distillery produces leaf biomass that can be mixed with binding agent(s) and transformed into biofuel as a sustainable alternative to traditional fuels. 14 biofuels were created by combining distillery leaf biomass and various percent …


The Role Of Frugivorous Birds As Seed Dispersers: Feeding Selection And Preference Of Madagascar’S Avian Frugivores In Analamazaotra Forest, Thaddeus Bashaw Oct 2022

The Role Of Frugivorous Birds As Seed Dispersers: Feeding Selection And Preference Of Madagascar’S Avian Frugivores In Analamazaotra Forest, Thaddeus Bashaw

Independent Study Project (ISP) Collection

Madagascar is a country rich in floral and faunal diversity. However, anthropogenic habitat destruction and climate change increasingly threaten its biodiversity. Endozoochorous plants that dependent on frugivory for seed dispersal are under threat due to increasing rates of localized extinctions of frugivorous lemurs, the primary seed dispersers of the island. While lemurs are the islands most abundant frugivores, other frugivorous vertebrates like birds and bats likely play a significant role in seed dispersal, although this role is still poorly understood. This study, conducted in Analamazaotra forest, compares the rates of visitation and consumption of six endemic fruiting tree species by …


A Quantitative Study Of Orchids And Their Proximate Environments Over An Elevational Gradient On The Northern Slope Of Montagne D’Ambre, Hazel Schrader Apr 2022

A Quantitative Study Of Orchids And Their Proximate Environments Over An Elevational Gradient On The Northern Slope Of Montagne D’Ambre, Hazel Schrader

Independent Study Project (ISP) Collection

This research investigated change in orchid populations and their proximate environments on the Northern slope of Montagne d’Ambre, a subhumid forest in Northern Madagascar. Orchid density, way of life (epiphyte or terrestrial), phenology, and associations were recorded over 100m elevation gradients and between forest types (primary, secondary, dry, and humid forests at the same altitude). Additionally, orchid preferences for certain heights in the forest and DBH of host trees were analyzed. The establishment of 50X20m plots in 100m elevation gradients combined with ground survey yielded significant results demonstrating change along with elevation as well as forest types. Orchid density increased …


The Battle For The Sea: Tourism Development And Public Ocean Access In Jambiani, Zanzibar, Sophie Beauchesne Apr 2022

The Battle For The Sea: Tourism Development And Public Ocean Access In Jambiani, Zanzibar, Sophie Beauchesne

Independent Study Project (ISP) Collection

The battle for coastal access is a prevalent and controversial issue in both the Global North and the Global South (Mongeau, 2001; Ojo, 2013). Due to investment in coastal land, vulnerable communities around the world are losing their access to the sea (Ojo, 2013; Bennett, Govan & Satterfield, 2015). Battles for ocean access in the Global North tend to focus on recreational activities, but what is to be said about ocean access in the Global South, where access to the sea is needed for the survival of entire communities? (Mongeau, 2001;). Using geographical mapping, environmental condition assessments and open-ended interviews …


Assessing The Threat Of Coral Decline On Fish Diversity In Response To Temperature, Ryland Talmadge Apr 2022

Assessing The Threat Of Coral Decline On Fish Diversity In Response To Temperature, Ryland Talmadge

Independent Study Project (ISP) Collection

Misali, a PECCA-protected island off the east coast of Pemba, Tanzania, is considered to be a marine biodiversity hotspot with a protected Non-Extractive Zone (NEZ) and remaining Extractive Zone (EZ). Upon protection, the island’s fringe reefs faced severe coral bleaching during the 1998 bleaching event, estimated to kill up to 70% of corals. Since the event, several others have occurred in addition to restructuring the management plan in 2006 to expand the region to 1000km. While the damage from the most recent coral bleaching event in 2020 has yet to be surveyed, this study investigates the current reef health in …
