Range-restricted species generally have specific niche requirements and may often have unique evolutionary histories. Unfortunately, many of these species severely lack basic research, resulting in poor conservation strategies. The phylogenetic relationship of the Critically Endangered Forest Owlet Heteroglaux blewitti has been the subject of a century-old debate. The current classifications based on non-phylogenetic comparisons of morphology place the small owls of Asia into three genera, namely, Athene, Glaucidium, and Heteroglaux. Based on morphological and anatomical data, H. blewitti has been alternatively hypothesized to belong within Athene, Glaucidium, or its own monotypic genus Heteroglaux. …

Climatic warming will likely have idiosyncratic impacts on infectious diseases, causing some to increase while others decrease or shift geographically. A mechanistic framework could better predict these different temperature-disease outcomes. However, such a framework remains challenging to develop, due to the nonlinear and (sometimes) opposing thermal responses of different host and parasite traits and due to the difficulty of validating model predictions with observations and experiments. We address these challenges in a zooplanktonfungus (Daphnia dentifera–Metschnikowia bicuspidata) system. We test the hypothesis that warmer temperatures promote disease spread and produce larger epidemics. In lakes, epidemics that start earlier and warmer in …

The increasing demand for healthy edible oil has generated the need to identify promising oil crops. Tree peony (Paeonia section Moutan DC.) is a woody oil crop with α-linolenic acid contributing for 45% of the total fatty acid (FA) content in seeds. Molecular and genetic differences that contribute to varied FA content and composition among the wild peony species are however, poorly understood. Analyses of FA content and composition during seed development in three tree peony species (P. rockii, P. potaninii, and P. lutea) showed varied FA content in the three species with highest in P. rockii, followed by P. …
Digging Out The Devils: Molecular Examination Of Amoeba-Like Cells From Cranial Tissue Of The Endangered Rio Grande Silvery Minnow, 2018 Old Dominion University
Digging Out The Devils: Molecular Examination Of Amoeba-Like Cells From Cranial Tissue Of The Endangered Rio Grande Silvery Minnow, Brandon Hamel
Undergraduate Research Symposium
The Rio Grande Silvery Minnow (Hybognathus amarus) is a critically endangered species native to the southwestern United States. Since the 1990s its population has declined dramatically due to extensive human alteration of the Rio Grande for agriculture and civil development. This has resulted in habitat degradation and impedance to proper migration, resulting in the minnow now occupying only 5% of its historical range. An active restocking and recovery program is underway through the US Fish and Wildlife Service involving breeding programs at three New Mexico sites. In the summer of 2012, aquaculture specimens began exhibiting an unusual spinning …

Eight-Legged Encounters—Arachnids, Volunteers, And Art Help To Bridge The Gap Between Informal And Formal Science Learning, 2018 University of Nebraska - Lincoln
Eight-Legged Encounters—Arachnids, Volunteers, And Art Help To Bridge The Gap Between Informal And Formal Science Learning, Eileen Hebets, Melissa Welch-Lazoritz, Pawl Tisdale, Patricia Wonch Hill
Eileen Hebets Publications
Increased integration and synergy between formal and informal learning environments is proposed to provide multiple benefits to science learners. In an effort to better bridge these two learning contexts, we developed an educational model that employs the charismatic nature of arachnids to engage the public of all ages in science learning; learning that aligns with the Next Generation Science Standards (NGSS Disciplinary Core Ideas associated with Biodiversity and Evolution). We created, implemented, and evaluated a family-focused, interactive science event—Eight-Legged Encounters (ELE)—which encompasses more than twenty modular activities. Volunteers facilitated participant involvement at each activity station and original …

Industries burn fossil fuels to create goods which releases carbon dioxide into the atmosphere. CO2 contributes to 20% of the world's greenhouse effect, and the level of it in the atmosphere has increased to over 400 ppm when before the French Revolution it fluctuated between 180-280 ppm (NASA, 2016). The coal industry is a big contributor as it contributes to 35% of the total U.S. energy related CO2 emissions (EIA, 2017). This all leads to global warming, which causes rising sea levels, longer plant growing seasons, and an increase in forest fires (NASA).

India is urbanizing very rapidly due to the movement of people from rural areas to urban cities for better opportunities. India does not have the resources or money to back this rapid urbanization of the population in general. This urbanization has created many environmental problems with air and water pollution.

Due to a lack of education among their population, many Brazilians turn to agriculture as a way to provide for themselves and their families. Additionally, low labor costs draw in large commercial companies that establish business in these developing worlds. However, to obtain farmland in the first place, deforestation has become a common practice, where thousands of miles of lush jungles are cleared away for agricultural practices. According to NASA imaging, 224,000 square miles of rainforest have been cleared in the Amazon. If left unchecked, the drastic consequences could harm not only the countries practicing deforestation, but the entire earth.

Biology Publications
Cold-acclimated insects defend ion and water transport function during cold exposure. We hypothesized that this is achieved via enhanced active transport. The Malpighian tubules and rectum are likely targets for such transport modifications, and recent transcriptomic studies indicate shifts in Na+-K+ ATPase (NKA) and V-ATPase expression in these tissues following cold acclimation. Here we quantify the effect of cold acclimation (one week at 12 °C) on active transport in the ionoregulatory organs of adult Gryllus pennsylvanicus field crickets. We compared primary urine production of warm- and cold-acclimated crickets in excised Malpighian tubules via Ramsay assay at a range of temperatures …
Acinetobacter Bacteriophage Discovery In Soil, 2018 Rose-Hulman Institute of Technology
Acinetobacter Bacteriophage Discovery In Soil, Michael Plaskett
Rose-Hulman Undergraduate Research Publications
The Acinetobacter genus is home to a wide range of bacteria that are gram-negative, aerobic, non-motile, oxidase-negative, catalase positive, and coccobacilli with a G+C content of 39 to 47% (Bergogne-Berezin, 1996). These bacteria are universal as they reside in the soil, water, sewage, various surfaces; and are also able to infect humans; however, a majority of the infections are caused by the species Acinetobacter baumannii. This bacterium is the most prevalent etiological cause of the Acinetobacter infections due to it being a nosocomial infection or one that is acquired in a health care setting. The infections that occur in a …
Investigating The Response Of Magnetotactic Bacteria To Varying Field Strength And Developing Autonomous Analysis Of Spatial Dispersal, 2018 Rose-Hulman Institute of Technology
Investigating The Response Of Magnetotactic Bacteria To Varying Field Strength And Developing Autonomous Analysis Of Spatial Dispersal, Madeleine D. Pasco
Rose-Hulman Undergraduate Research Publications
Magnetotactic bacteria (MTB) are single-celled organisms which contain organelles called “magnetosomes,” membrane-bound ferrous nanocrystals. These organelles allow for magnetotaxis, which is movement guided by magnetic fields. MTB are generally found in the top layers of sediment of aqueous environments, and magnetotaxis is thought to help guide these microbes to ideal oxygen concentrations in the water after they may have been displaced by turbulent waters. In this we study the effect of the strength of a magnetic field on magnetotaxis.
