Variation Of Carbon Stock Of Boca Del Drago Mangrove Forests Based On Salinity And Seaward Proximity, Fiona Wyrtzen
Independent Study Project (ISP) Collection
Mangrove forests, at the intersection of land and sea, are considered one of the most important marine environments for their variety of ecosystem services and their ability to sequester large amounts of carbon in their biomass and adjacent soils. With a changing climate, many of the abiotic and biotic factors influencing mangroves will begin to shift, potentially impacting resilience, growth capacity, and distribution of mangroves worldwide. This study aimed to examine the influence of changing salinity on the carbon stock capacity for Rhizophora mangle and Laguncularia racemosa forests, and the distribution of biomass in each species relative to salinity in …
Representations And Realities: Misali Island's Biodiversity In Hybrid Narratives, Justin Ross Whitney
Representations And Realities: Misali Island's Biodiversity In Hybrid Narratives, Justin Ross Whitney
Independent Study Project (ISP) Collection
Marine Protected Areas (MPAs) are complex organisms that ebb and flow between strict and unyielding conservation doctrines often at the cost of community engagement. Misali Island is different. Conceived and advocated for by community members, this organism has navigated a tumultuous tenure of environmental degradation, periods of high and low funding, and a looming tourism presence. On top of these challenges has been a growing fishing community attempting to share in the bounty of this shockingly biodiverse setting. This study sorts through the grey space of Misali Island by applying a hybrid narrative that interfaces the marine context of the …

Introduction: Coastal estuarine wetlands provide important habitats for a variety of endemic flora and fauna but are particularly vulnerable to biological invasions. Regular monitoring of changes in these vulnerable wetlands has become increasingly important for effective management, especially considering threats from climate change effects and human disturbance. Historical analyzes of plant invasions may guide targeted management strategies to eradicate harmful species. Estimating the distribution of invasive species has never been more accessible with the improved availability of high-resolution data and innovations in remote sensing, estimating the distribution of invasive species has never been more accessible.
Methods: We assessed the spread …

Bura Ura, Kendu Waiyo (Rain Falls, Water Rises): The Tyranny Of Water Insecurity And An Agenda For Abolition In Kodi (Sumba Island, Indonesia), Cynthia Twyford Fowler
Faculty Scholarship
This article explores the dynamic links between transformations in freshwater ecosystems and social changes in the Kodi region of Sumba (Indonesia). Insights into the politics surrounding changing hydrosocial systems are generated by using a feminist anthropology approach together with critical development studies and intersectionality theory. In aligning with fellow feminists whose advocacy sometimes takes the form of scholarship, I lay out a five-prong strategy for collecting empirical evidence from persons who are vulnerable when hydrological systems change and offer eight principles for future development interventions. The argument related to the five-prong toolkit is that by conducting intensive, extensive, opportunistic, and …
Real-Time Mapping With Global Positioning Systems Devices In A Mixed Methods Toolkit For Studying Social And Environmental Change, Cynthia Twyford Fowler
Real-Time Mapping With Global Positioning Systems Devices In A Mixed Methods Toolkit For Studying Social And Environmental Change, Cynthia Twyford Fowler
Faculty Scholarship
To explore the process through which people develop knowledge about socioecological change, this article describes a mixed-methods toolkit containing a technique for making maps in real time while moving through landscapes. The quantitative component of the toolkit is grounded in ethnobiologists’ embeddedness in place-based communities and harnesses the power of global positioning systems (GPS). As GPS-wielding ethnobiologists engage in participatory mapping by moving through landscapes with their research collaborators, we can use handheld devices and simultaneously communicate with satellites in outer space to produce maps in real time. Within the existing, large inventory of ethnobiological methods, using handheld GPS devices …
Understory Epiphyte Hydrology: Analyzing Water Storage Capacity Of Epiphytes Along An Elevational Gradient In Western Ecuadorian Cloud Forest, Angelina Dodge
Understory Epiphyte Hydrology: Analyzing Water Storage Capacity Of Epiphytes Along An Elevational Gradient In Western Ecuadorian Cloud Forest, Angelina Dodge
Independent Study Project (ISP) Collection
Epiphytes are defined as plants that grow on a host, often another plant, and acquire their nutrients and water from the atmosphere. As such is true, epiphyte composition is largely dependent upon atmospheric and thus climactic conditions. Due to high levels of atmospheric water availability that results from the frequent presence of mist, clouds, and high humidity, epiphytic plants grow and thus store water within the above ground region of the Andean cloud forest at levels higher than in any other ecosystem found in Ecuador. This study was done in hopes of revealing any trends of epiphytic water storage capacity …

The dynamics of marine systems at decadal scales are notoriously hard to predict-hence references to this timescale as the "grey zone" for ocean prediction. Nevertheless, decadal-scale prediction is a rapidly developing field with an increasing number of applications to help guide ocean stewardship and sustainable use of marine environments. Such predictions can provide industry and managers with information more suited to support planning and management over strategic timeframes, as compared to seasonal forecasts or long-term (century-scale) predictions. The most significant advances in capability for decadal-scale prediction over recent years have been for ocean physics and biogeochemistry, with some notable advances …

Artistic Engagement With Monadnock: A Hermeneutic Phenomenological Study, Jonathan W. Coffin
Artistic Engagement With Monadnock: A Hermeneutic Phenomenological Study, Jonathan W. Coffin
Antioch University Dissertations & Theses
This hermeneutic phenomenological study discloses the lived experience of creating art in association with New Hampshire’s Mount Monadnock. This study reveals the potential for artistic invention in association with place gradually to undermine an established sense of separation from environment and to prompt conscious awareness of continuity with environment. A series of interviews with four artists who create art of or in the presence of Monadnock revealed in the lived experience of creating Monadnock art a process that consists of five phases: first encounter, abstract appreciation, existential understanding, sustained attention, and continuity. A hermeneutic circular method of interpretation based upon …
Orb-Weaver Diversity And Niche Partitioning In Ecuador’S Amazonian Foothills: What Spiders Can Reveal About Tree Fall Gaps, Streams, And Cultivated Areas, Riley Endries
Independent Study Project (ISP) Collection
As abundant predators at the top of arthropod food chains, spiders are excellent bioindicators. Araneae is a megadiverse and extremely understudied order, especially in the tropics. This study aims to investigate the diversity of orb-weaver spiders across a disturbance gradient and variety of habitat types as well as their microhabitat preferences and potential niche partitioning. Spider collection was performed on spiders of the families Araneidae, Tetragnathidae, and Theridiosomatidae in Sumak Kawsay in Situ biological reserve in the lower elevation cloud forest of Ecuador’s Andean foothills. Spiders and webs were observed and analyzed from primary and secondary forest tree fall gaps, …

Estimating Fish Diet In Lake Turkana, Kenya, Julia G. Sharapi
Estimating Fish Diet In Lake Turkana, Kenya, Julia G. Sharapi
Student Publications
Lake Turkana, located in northern Kenya on the Ethiopian border, is the world’s largest permanent desert lake. Over 90% of its flow originates from the Omo River in Ethiopia, which causes the lake to have seasonal rises and falls in water level. The Omo River has been subject to the construction of five dams (the Gilgel Gibe dams) and several irrigation projects. These developments will impact the amount of water entering the lake, with implications for lake chemistry and productivity, littoral habitat availability, and the breeding biology of the lake’s fishes. Though ongoing upstream changes are likely to have serious …
The Relationship Between Substrate Composition, Community Structure And Feeding Preferences Of Parrot Fishes (Scaridae) In Anmardub, Guna Yala Coastal Reefs, Caitlin Amman
Independent Study Project (ISP) Collection
Coral reefs are important marine ecosystems, as they support biodiversity and generate buffer zones, yet their abundance is incredibly limited globally. One of the main threats that coral reefs face is excessive macroalgal coverage, which limits sunlight from reaching corals, and thus, limits the energy that can reach them. Parrot fish (Scaridae) are keystone herbivores, as they consume macroalgae growing on corals, which aids in reef survivability. While there is previous research on the abundances, sizes, and feeding habits of Scaridae species in the Caribbean, there is no published research on how community structure and feeding preferences of parrot fishes …
S5e11: Why Might Maine Lose Two Species Of Songbirds?, Ron Lisnet, Katherine Ruskin, Brian Olsen
S5e11: Why Might Maine Lose Two Species Of Songbirds?, Ron Lisnet, Katherine Ruskin, Brian Olsen
The Maine Question
Maine may lose two tidal marsh songbird species in the next few decades. Saltmarsh sparrows face extinction, while Acadian Nelson’s sparrows are threatened with extirpation — localized eradication with the possibility of survival elsewhere. Their populations along the Eastern Seaboard have been declining as sea level rise destroys their habitats and, according to a new University of Maine-led study, mercury exposure inhibits their reproduction.
In the final episode of Season 5 of “The Maine Question,” Kate Ruskin, a lecturer in ecology and environmental science at UMaine who spearheaded the recent mercury exposure study, and Brian Olsen, who is now an …

A Ladder Of Endemicity: A Pioneering Study Of Anuran Communities Along An Elevational Gradient In The Eastern Andean Cloud Forests, Ecuador, Ella Halbert
Independent Study Project (ISP) Collection
Per unit of area, Ecuador is home to the most herpetofauna of any region on Earth, yet many ecosystems are under researched. Positioned between the Eastern Andes and the Amazon rainforest, the Río Pastaza Basin of Ecuador has been the recent focus of anuran biodiversity surveys and is home to many endemic species. This study aimed to determine how the anuran community composition of a vertical transect in the Llanganates National Park varied between elevations. A 7-day expedition was conducted along a new trail up Abitagua Range spanning 1,050 m in elevation. Each night, visual encounter surveys were employed to …
Otoliths Of South-Western Australian Fish: A Photographic Catalogue, Chris Dowling, Kim Smith, Elain Lek, Joshua Brown
Otoliths Of South-Western Australian Fish: A Photographic Catalogue, Chris Dowling, Kim Smith, Elain Lek, Joshua Brown
Fisheries research reports
Due to the species-specific nature of otoliths and given they are often the only part of the fish preserved when fish die, otolith catalogues can be used in numerous applications, such as diet studies in fish eating animals, including pinnipeds, fish and sea birds; archaeological purposes such as reconstructing indigenous people’s diets from otoliths found in middens or evolutionary history of fish species by comparing fossilized otoliths. Given the unique mixture of subtropical and temperate fish, including many endemic species that occur off the southwest corner of WA having a catalogue for this area is extremely important for people working …

Representation Justice As A Research Agenda For Socio-Hydrology And Water Governance, Melissa Haeffner, Dana E. Hellman, Alida Cantor, Idowu Ajibade, Vinka Oyanedel-Craver, Maura Kelly, Laura Schifman, Lisa Weasel
Environmental Science and Management Faculty Publications and Presentations
We propose representation justice as a theoretical lens for socio-hydrology and water governance studies. An exploratory survey of 496 water sector employees in the United States revealed that self-identifying females felt more strongly discriminated against due to their gender and other social factors, compared to self-identifying males. Responses unveiled how macro- and microaggressions impede career pathways to leadership positions and, therefore, representation. We identify ways in which socio-hydrology can benefit from a representation justice lens by considering the following: (1) how power and politics shape the composition of the water sector and decision-making processes; (2) how available quantitative data do …

A Fused Radar–Optical Approach For Mapping Wetlands And Deepwaters Of The Mid–Atlantic And Gulf Coast Regions Of The United States, Brian T. Lamb, Maria A. Tzortziou, Kyle C. Mcdonald
Publications and Research
Tidal wetlands are critically important ecosystems that provide ecosystem services including carbon sequestration, storm surge mitigation, water filtration, and wildlife habitat provision while supporting high levels of biodiversity. Despite their importance, monitoring these systems over large scales remains challenging due to difficulties in obtaining extensive up-to-date ground surveys and the need for high spatial and temporal resolution satellite imagery for effective space-borne monitoring. In this study, we developed methodologies to advance the monitoring of tidal marshes and adjacent deepwaters in the Mid-Atlantic and Gulf Coast United States. We combined Sentinel-1 SAR and Landsat 8 optical imagery to classify marshes and …

Independent Study Project (ISP) Collection
Mangroves make up one of the most effective natural remedies at combating climate change today. They represent great commercial interest worldwide and yet, are being degraded at an unsustainable rate. If successful mangrove conservation plans are to be implemented for our posterity, mangrove ecosystems need to be better understood at the community level. Mangrove crabs make up the most diverse and populace mangrove inhabitants. They are classified as ecosystem engineers and their potential for being used as bioindicators makes them integral to assessing mangrove health. Yet, their diversity and distribution patterns are not well understood. The aim of this study …

Undocumented historical losses of sea turtle nesting beaches worldwide could overestimate the successes of conservation measures and misrepresent the actual status of the sea turtle population. In addition, the suitability of many sea turtle nesting sites continues to decline even without in-depth scientific studies of the extent of losses and impacts to the population. In this study, multidecadal changes in the outlines and area of Jana and Karan islands, major sea turtle nesting sites in the Arabian Gulf, were compared using available Kodak aerographic images, USGS EROS Declassified satellite imagery, and ESRI satellite images. A decrease of 5.1% and 1.7% …

Heterospecific breeding associations may benefit individuals by mitigating predation risk but may also create costs if they increase competition for resources or are more easily detectable by predators. Our understanding of the interactions among hetero- and conspecifics is often lacking in mixed species colonies. Here, we test how the presence of hetero- and conspecifics influence nest and chick survival for two listed (under the U.S. Endangered Species Act) migratory species breeding on the Missouri River, USA. We monitored 2507 piping plover Charadrius melodus nests and 3245 chicks as well as 1060 least tern Sternula antillarum nests and 1374 chicks on …

A Survey Of Dairy-Goat Keeping In Zanzibar, Tiffanie Stone, Charles A. Francis, L. O. Eik
Department of Agronomy and Horticulture: Faculty Publications
Dairy goats with improved genetics for milk production were recently introduced onto small-scale farms in Zanzibar through governmental and non-governmental projects. These projects were meant to support small-scale farmers by improving both income and household nutrition through milk production. No follow up had been conducted to understand what effects dairy goat keeping had on these small-scale farms, or how they could be improved. A survey of 193 dairy goat farmers in Zanzibar was conducted, including 30% and 60% of all dairy goat farmers on Unguja and Pemba, the two largest islands, respectively. The objective was to understand the impact keeping …

Vegetation is an important ecological component of offshore islands in the Arabian Gulf (AG), which maintains long-term resilience of these islands. This is achieved by influencing sediment retention and moisture acquisition via condensation during periods of high humidity and by providing a variety of microhabitats for island fauna. The resilience of offshore islands’ ecosystems in the Saudi waters is important because they host the largest number of nesting hawksbill and green turtles in the AG. This study defines the characteristics and the long-term trends in vegetation cover of the offshore islands used by sea turtles as nesting grounds in the …
