Study Of The Visual Adaptation Mechanism In Marine Species With The Change Of Habitation Depth., Demid Osipov, Daniil Moshnikov Jun 2018

Study Of The Visual Adaptation Mechanism In Marine Species With The Change Of Habitation Depth., Demid Osipov, Daniil Moshnikov

The International Student Science Fair 2018

The goal of our work was to determine the principal mechanisms that provide the difference in visual perception of two marine species that live on different depths: T. Pacificus and O. Vulgaris. In nature, visual perception of species that live deeper is shifted towards the blue region. This is related to the fact that red, orange and yellow light is absorbed more strongly by water than the blue light. On the other hand, the visual perception spectrum of an animal is determined by the absorption spectrum of the "light sensor" located in rods and cones of its eye retina. These …


Effects Of Water Contaminants On The Immune System Of The Fathead Minnow, Jacob B. Walling, Marina Cetkovic-Cvlje Apr 2018

Effects Of Water Contaminants On The Immune System Of The Fathead Minnow, Jacob B. Walling, Marina Cetkovic-Cvlje

Award for "Best Undergraduate Oral Presentation".

Abstract

Contaminants of emerging concern (CECs), including personal care products, pharmaceuticals, industrial agents and agricultural runoff, have shown adverse effects on aquatic survival species. Numerous CECs have potentially harmful effects, but have not been well studied. One of the most alarming studies was the treatment of an entire lake with a synthetic estrogen, found in birth control pills, which showed a near extinction of the fathead minnow population. My study looks at the potential effects of CECs on the immune system of fathead minnow. This study does not only show the potentially hazardous effects …

Award for "Runner-Up Graduate Oral Presentation".

Abstract

Contaminants of emerging concern (CECs) have shown adverse effects on aquatic survival species, but little research has been done on the potentially harmful impact of CECs individually or combined. Anecdotal evidence and newspaper articles have reported mass extinctions of fish due to CECs in the water. This study looks at the potential effects of CECs on the immune system of fathead minnow. This study does not only show the potentially hazardous effects CECs have on one aquatic species, but may give an insight on how some of these chemicals may affect other species, …

Rising sea surface temperatures (SSTs) in the Pacific Northwest lead to food resource reductions for surface-feeding seabirds, and have been correlated with several marked behavioral changes. Namely, higher SSTs are associated with increased egg cannibalism and egg-laying synchrony in the colony. We study the long-term effects of climate change on population dynamics and survival by considering a simplified, cross-season model that incorporates both of these behaviors in addition to density-dependent and environmental effects. We show that cannibalism can lead to backward bifurcations and strong Allee effects, allowing the population to survive at lower resource levels than would be possible otherwise.
