Exploring Secondary Metabolite Profiles Of Sloth Algae, Valerie Quach, Paige Smith
Exploring Secondary Metabolite Profiles Of Sloth Algae, Valerie Quach, Paige Smith
Honors Theses
In this experiment, we investigated the composition of the secondary metabolites in sloth algal cultures. Additionally, we investigated the effects of secondary metabolites in sloth algal cultures on insects. The three outlets of investigation include insect avoidance tests, sending samples to the Natural Center for Natural Products Research, and analyzing sequencing data with AntiSMASH to identify secondary metabolite biosynthetic gene clusters. While our data from the Drosophila fly tests were inconclusive, we found that our samples contain many different gene clusters for terpenes, NRPS, PKS, RiPPs, which are volatile compounds with a wide array of biosynthetic functions. This research can …
Responses Of The Carnivorous Pink Spoonleaf Sundew (Drosera Capillaris) To Nitrogen Addition, Phosphorus Addition, And Simulated Fire, Karina Rodriguez Castillo
Responses Of The Carnivorous Pink Spoonleaf Sundew (Drosera Capillaris) To Nitrogen Addition, Phosphorus Addition, And Simulated Fire, Karina Rodriguez Castillo
Honors Theses
This study investigated how the carnivorous plant, Drosera capillaris(pink sundew), responded to changes in the resources of its habitat, the fire-prone, nutrient-poor wet savannas. It is of interest to determine what soil nutrient(s), nitrogen or phosphorus, limits the survival and growth of pink sundew, and to what extent, if any, does fire affect the survival and growth of this carnivorous plant. My field experiments had twenty plots with two replicate groups consisting of four pink sundews in each plot. From the fall of 2017 to the fall of 2019, only half of the plots were clipped annually, and there …
The Importance Of A Multidisciplinary Approach To Public Health: Addressing Food Insecurity Through A Biological And Sociological Lens, Chloe Grant
Honors Theses
Plants can sense the change of 1 oC in their growth environment and thus global climate change has a great impact on plant growth and development. The phenomenon that warm non-stress temperatures promote stem and petiole elongation, as well as leaf hyponastic growth, is collectively known as thermomorphogenesis. While it is known that the basic helix-loop-helix (bHLH) transcription factor PIF4 is highly inducible by temperature elevations and controls thermomorphogenesis in dicots (e.g., Arabidopsis thaliana), the molecular mechanism underlying thermomorphogenetic growth in monocots is not clear. In this study, I identify PIF4 orthologs in several economically important monocotyledonous species and …
A Baseline Documentation Report For The Delta Wind Birds Sky Lake Nature Reserve, James Dubberly
A Baseline Documentation Report For The Delta Wind Birds Sky Lake Nature Reserve, James Dubberly
Honors Theses
The purpose of this baseline documentation is to conduct a report on our subject property and discuss the findings. A conservation easement is established by upholding a certain standard of a property’s current condition which makes a baseline documentation necessary for an easement to be enacted. Baseline documentation reports are used as a resource to monitor and enforce the legal agreements of the conservation easement. The subject property is currently owned by the Delta Wind Birds organization. In our scenario, this documentation report will serve to aid in the conversion of our subject property into a conservation easement in which …
Transcriptional Activation Of Phytochrome-Interacting Factor 4 Is A Conserved Mechanism Of Thermomorphogenesis In Dicotyledenous Plants, Caroline Clutton
Transcriptional Activation Of Phytochrome-Interacting Factor 4 Is A Conserved Mechanism Of Thermomorphogenesis In Dicotyledenous Plants, Caroline Clutton
Honors Theses
In the model dicotyledonous plant Arabidopsis thaliana, the basic helix-loop-helix (bHLH) transcription factor Phytochrome-Interacting Factor 4 (AtPIF4) plays a central role in regulating the ambient temperature-regulated hypocotyl growth response. Warm temperatures induce AtPIF4 transcription and the accumulated AtPIF4 promotes thermomorphogenesis by enhancing the expression of a group of growth-related genes. However, whether this thermo-induced growth response is universal, and more importantly, whether there is a conserved thermomorphogenetic mechanism shared in dicots is largely unknown. Here we show that higher ambient temperatures promote the hypocotyl growth in four other dicotyledonous plants, including Brassica rapa, Camelina sativa, Nicotiana benthamiana …

Survey Of The Native And Nonnative Vascular Plant Species Of Three Islands In Lake Winnipesaukee, New Hampshire, Mark Gardner Winkler
Survey Of The Native And Nonnative Vascular Plant Species Of Three Islands In Lake Winnipesaukee, New Hampshire, Mark Gardner Winkler
Electronic Theses and Dissertations
This study examined the long-term patterns in vascular plant composition on three islands in Lake Winnipesaukee, NH. It also tested the role of island biogeography in ecology as it analyzed the effectiveness of a land use plan implemented on the islands. Samplings were made on the islands in the summer of 2011 and were compared to earlier samplings in 1978, 1991, and 2001. The flora was observed and measured in 25 permanent plots that were established on the three islands in 1978. The understory flora was measured by presence and percent cover and the overstory was measured by frequency and …
Science Based Authentication Of Dietary Supplements: Studies On The Chemical Constituents, Analytical Method And Biological Activities Of Scutellaria Spp And Pfaffia Paniculata, Jing Li
Electronic Theses and Dissertations
During the last decade, the use of herbal medicine has expanded globally and gained popularity. With the tremendous expansion in the use of herbal medicine worldwide, safety and efficacy as well as quality control of herbal medicines have become more and more issues of concern for both health authorities and the public. Although herbal medicine has been in use for hundreds to thousands years, very limited science-based data exist to explicit its chemical constituents, pharmacological activities and toxicity. Therefore, lack of scientific evidence for herbal medicine usage elicits the need for systematic studies of herbal medicine, including phytochemical, analytical, and …
