Upon entering a residential drug and alcohol treatment, typically clients are directed to complete a risk assessment form. Risk assessment forms are anonymous, self-reported questionnaires that inquire about demographics, health, sexual behaviors, as well as drug and alcohol use. The YES house is a youth treatment facility in Corvallis Oregon...
Most animals are active either during the day, night, or twilight, and transition periods between these times exhibit interesting behavior. Actions may be related to avoiding predators, seeking shelter, defending territory, feeding, or other interests. Herbivorous fishes on coral reefs, such as parrotfishes, forage constantly throughout daylight periods due to...
Sea stars are well known on the Pacific coast as being keystone species. Pisaster ochraceus plays a major role in controlling the lower limits of the high zone mussel beds, normally preying on medium to large-sized species. Leptasterias hexactis is often found feeding on smaller prey. According to the competitive...
Saccharina sessilis, lettuce kelp, is a macroalgae that contributes to the primary production in the intertidal zone off of the Oregon Coast. Macroalgae can serve as a bioindicator of increased nutrient input, water quality, and shifts in the intertidal environment. Competition for light exists between macroalgae species and with other...
Pollination is a critical ecosystem function for sustaining biodiversity. However, pollinators and the services they provide are threatened by landscape-altering anthropogenic activities across the globe. Habitat loss and fragmentation, introduction of invasive species, chemical use, and urbanization have been shown to impact pollination. Pollinator foraging behavior is thought to be...
Approximately 37.6% of Fiji’s population is comprised of individuals that have Indian descent (2007 census). This is primarily due to the recruitment of Indian indentured servants to work on the sugar plantations of Fiji during British colonial rule in the 1880s. Many descendants of these servants have since moved to...
Ocean acidification has led to many issues regarding the decline of calcifying organisms, such as
coralline algae. Acidified sea water inhibits precipitation of CaCO3 that affects the structure and
growth of coralline algae. Therefore, non-calcifying algae may outcompete calcifying algae in the
intertidal systems with future acidic ocean condition. Variety...
Coral reefs have become extremely vulnerable to rising ocean temperatures, with mass bleaching events increasing in frequency and severity. If bleaching events persist annually, models predict that more than 90% of reef species will face long-term degradation. However, recent evidence has shown that corals may be able to thermally acclimate...
Symbioses are intimate interactions between two different organisms. In a pathogenic interaction, one organism benefits and the other is generally harmed; whereas in a mutualistic interaction, the members reciprocally benefit. Rhodococcus is a genus of Gram-positive bacteria that persist in a variety of terrestrial and aquatic ecosystems. Although better known...
The symbiotic relationship between cnidarians and algae is important to the marine ecosystem due to the photosynthesis produced by the algae and the coral reefs that cnidarians provide. Corals provide their algal partner with a safe home and the algae supply the cnidarians with inorganic materials as a food source....
The rocky shores of the US West Coast are home to diverse ecological communities made up of species that are uniquely adapted for survival at the harsh boundary between land and sea. Even so, physical or environmental stressors regularly kill swaths of animals on the rocks. This is called disturbance....
Presented via Zoom at the OSU Religious Studies 2021 Spring Conference.
This paper takes an analytical look at the 2014 Supreme Court Case Burwell v Hobby Lobbly. This case is an example of the intersection of religion with capitalism, healthcare, feminism, and public policy. This case looks to answer the...
Nutrients play a large role in sustaining the symbiotic relationship between the algae and host sea anemone. The endosymbiotic algae provides the host with fixed nitrogen, sugars, and inorganic food sources, while the host provides the algae with shelter and nitrogenous waste. If the anemone does not receive the proper...
Giardia and Cryptosporidium protozoans are resilient, zoonotic waterborne pathogens that can bypass water treatment and kill millions of people and animals annually. Giardia and Cryptosporidium cysts and oocysts, respectively, can spread through feces; poor sanitation and poverty can increase the risk for giardiasis and cryptosporidiosis diarrheal diseases. We are currently...
