Distribution of Daphnia resting eggs: Invasive vs native and their effects
(Oklahoma State University, 2019-04-27)
Daphnia lumholtzi is an example of a successful aquatic invasive species. When conditions are less favorable, D. lumholtzi switch from producing female eggs to the production of diapausing eggs (called ephippia) that are ...
Determining the role of Gɑ3, Gɑ8, and PakF in Dictyostelium signaling
(Oklahoma State University, 2019-04-27)
Dictyostelium discoideum is a free-living amoeba found in the soil. Dictyostelium (commonly referred to as "slime mold") exists as a unicellular amoeba in optimal environmental conditions. In suboptimal conditions (specifically ...
Evaluating the core microbiome of Manduca sexta
(Oklahoma State University, 2019-04-27)
Microbiomes are complex communities of microorganisms that colonize many surfaces of an animal's body, especially those niches lined with carbohydrate-rich mucosal layers such as the eyes, male and female reproductive ...
Feeding behavior of Acheta domesticus infected with Paragordius varius
(Oklahoma State University, 2019-04-27)
There has not been a lot of research on the phylum nematomorpha, hairworms. There is a large gap in the knowledge of hairworms in their host-parasite relationship, especially on their dietary habits. Our study observed the ...
Single step polyfluoroarylation of amides
(Oklahoma State University, 2019-04-27)
Per- and polyfluoroarenes are important synthetic chemistry targets because they are active components in many pharmaceuticals, agrichemicals, and industrial manufacturing products. Many of the current methods of synthesizing ...
Examining the role of MekA and YakA in Dictyostelium signaling
(Oklahoma State University, 2019-04-27)
A series of trials were conducted to determine how each protein or kinase plays a role in the signaling of a cell. Among the factors tested were response time, extent of response, and the response under varying stimuli ...
Predator-prey interactions with Physa acuta
(Oklahoma State University, 2019-04-27)
Freshwater communities can be complex with the predatory strategies that take place within them. Gastropods are an example of a typical prey that is found within these freshwater communities. Their predators give off a ...
Interacting effects of soil microbes and spiders on plant growth
(Oklahoma State University, 2019-04-27)
Biotic factors contribute greatly to the success of nutrient cycling, this is done by recycling and translocating nutrients microbe. Research has shown that high densities of predators affect the amount of nutrients deposited ...
Cellular senescence in cultured human brainstem astrocytes: Effect of oxidative stress
(Oklahoma State University, 2019-04-27)
Cardiovascular diseases are one of the leading causes of mortality in the elderly. A central role in the contraction of cardiovascular diseases by means of aging could be played by cellular senescence. Senescent cells ...
Dying light: Detecting tree mortality risk with chlorophyll fluorescence
(Oklahoma State University, 2019-04-27)
Increased greenhouse emissions have altered Earth's climate, resulting in rapid climate change which has brought warm droughts-especially in semi-arid regions-leading to forest die-off and dieback. Physiological stresses ...
