Macroinvertebrate Community And Temperature Changes In A Michigan Stream, Nyika Campbell
Macroinvertebrate Community And Temperature Changes In A Michigan Stream, Nyika Campbell
Independent Study Project (ISP) Collection
As the climate warms, global biodiversity is plummeting and extinction rates are rising (Jenkins, 2003). Freshwater ecosystems specifically are experiencing huge losses in diversity (Jenkins, 2003; Ormerod et al., 2010; Collier et al., 2016). Conservation of invertebrates is particularly urgent because they are foundational to the trophic systems in streams and lakes, comprising 95% of all species on earth (Titley et al., 2017), and over 60% of biodiversity in freshwater ecosystems (Collier et al., 2016). Through analysis of both my own field measurements and historical data I seek to gain a preliminary understanding of temperature and macroinvertebrate community changes that …
Conservation Efforts Concerning Native Bee Species Of Michigan, Thomas Hellman
Conservation Efforts Concerning Native Bee Species Of Michigan, Thomas Hellman
Independent Study Project (ISP) Collection
Bee species all over the world are declining at concerning rates. However, it is good to see the public rallying behind the “save the bees!” movement even though most efforts from this movement have been on the conservation of the European honeybees. This is because most people often associate the honeybee, which is only one of 20,000 known bee species in the world, to all other bees. Therefore, conservation efforts should be broadened and aimed towards the many native bee species that can be found locally in North America. In the state of Michigan, there are over 450 species, and …
Crude Intentions: Evaluating The Growing Risks Of Arctic Alaskan Oil Production, Eliot Stein
Crude Intentions: Evaluating The Growing Risks Of Arctic Alaskan Oil Production, Eliot Stein
Independent Study Project (ISP) Collection
The discovery of oil on Alaska’s North Slope in the 1920s began a century of fossil fuel exploration, development, and production in the Arctic region. Alaska became integral to the nation’s growing energy dominance. However, since 1988, oil production on the North Slope has been in steady decline. In 2015, Shell, followed by several other oil majors, terminated their Arctic Alaska operations. This past year, BP made waves by ending six decades of operations in Alaska. Most recently, five of the six major U.S. banks announced they would no longer finance Arctic oil and gas projects. This paper analyzes these …

Understanding processes and ecological threats occurring at the watershed level scale composes a critical piece of water resource conservation and management. This proves doubly true in areas such as the Ecuadorian highlands where water resources depend heavily on the hydrologic regulation capacities of páramo soils. This study examined watershed condition of the Rio Tomebamba watershed and existing habitat for Metallura baroni and Chibchanomys orcesi, two highly endemic species, within its boundaries. Watershed condition was determined based on a simple index that considered nine indicators of watershed health—converted land, impacted riparian zones, impermeable surfaces, water quality, fluvial habitat condition, riparian vegetation …
The Influence Of Location, Positioning, And Seasonality On Feeding Behavior Of The Sydney Oyster (Saccostrea Glomerata) In New South Wales, Australia, Nathaniel Hess
Independent Study Project (ISP) Collection
Oysters are hard shelled bivalves that aggregate over time to create structures in estuarine systems, known as oyster reefs. These reefs are important for the promotion of estuarine biodiversity by supporting many species of fish, invertebrates, and plants. They also act as a key contributor to water health by using active suspension feeding mechanisms and selective feeding to remove nutrients and water borne pollutants from estuarine systems. They have been touted as possible bio-remediators. They also effect rates of sedimentation in estuaries.
Oyster reefs have historically been threatened by anthropogenic influences such as overharvesting, destructive fishing practices, water pollution, CO2 …

We defined habitat types defined by two variables: type of forest and proximity to water. The aim of the study was to determine what effect each variable has on anuran community composition. We compared the effectiveness of the two survey methods as well. High anuran community dissimilarity was found between each habitat type surveyed, indicating that both forest type and proximity to water are important factors that shape species richness …
36 Years After The Species' Mass-Mortality: Diadema Antillarum Test Sizes, Population Densities, And Substrate Preferences In Three Guna Yala Reefs Near Wichub Wala Island, Bimini Horstmann
Independent Study Project (ISP) Collection
In January 1983, a waterborne pathogen beginning near the Atlantic Panama Canal entrance caused history's largest recorded marine animal die-off, wiping out 95-99% of Diadema antillarum populations throughout the Caribbean. D. antillarum, the long-spined sea urchin, is a keystone herbivore in coral reefs and its decreased densities have caused many reefs to suffer macroalgal phase shifts. Modest recovery of this species has been documented in some Caribbean locations, but reefs in Guna Yala, Panama continued to experience population decline. This study investigates density, test size, and substrate preferences of D. antillarum in three shallow coral reef areas to update the …

Sea turtles rely on unspoiled beaches with particular physical characteristics for laying their eggs. One of the …
Avian Upsloping In The Tropics: Myioborus Miniatus And Myioborus Torquatus Abundance In Different Altitudinal Ranges In Boquete, Chiriquí, Panama, Julie Yoon
Independent Study Project (ISP) Collection
Direct and indirect effects of warming global temperatures due to climate change are known to cause upwards shifts of the altitudinal ranges of some avian species. Most susceptible to this trend and at risk of riding the “escalator to extinction” are endemic species in tropical montane cloud forests, such as Myioborus torquatus. There are abiotic factors, like temperature, and biotic interactions, such as the presence of its altitudinal neighbor Myioborus miniatus, that limit the altitudinal range of this bird species in the Neotropics. This study measured abundance of M. miniatus and M. torquatus populations at different altitudinal ranges by point …
