Factors Influencing The Current And Historical Invasion Trends In The Connecticut College Arboretum, Lillian Fayerweather
Factors Influencing The Current And Historical Invasion Trends In The Connecticut College Arboretum, Lillian Fayerweather
Botany Honors Papers
Invasive species present a growing risk to native ecosystems. It would be impossible to eliminate them, but by learning where they are more likely to occur it may be possible to concentrate resources on removal and management in the most at risk areas. A number of site characteristics may influence invasive species presence and invasion trends. In order to determine what factors affect species presence and historical invasion trends, I utilized data from decennial surveys conducted in the Bolleswood Natural Area of the Connecticut College Arboretum in New London, Connecticut. In 1952, 4 transects were established across the area, composed …

La producción de semilla artesanal de sorgo es un complemento en la producción y uso de semilla certificada y tiene como objetivo el de atender a los agricultores que por diversas razones no acceden a la semilla certificada, pero son sujetos potenciales de producción y desarrollo del cultivo de sorgo. En términos generales son los agricultores de menos recursos, que representan la mayoría de productores de sorgo en América Central, los que se ven limitados a la utilización de las variedades mejoradas. Debemos de meditar sobre la utilización de las variedades mejoradas de polinización libre y probablemente el poco acceso …

Theses, Dissertations and Capstones
With the increasing influence in climate change and human activity, more and more people have begun to recognize the benefits of wetlands. However, there was a continuous annual net loss in the wetlands area since 1980s. Many programs have been implemented to monitor the status and trend of wetlands recently. In West Virginia, the wetlands area is a small portion of the State’s land, but it plays a key role in the whole ecosystem. This research aimed to detect the land cover and vegetation changes focusing on Canaan Valley area, which represents the greatest wetlands area of West Virginia. Remote …

Beech Bark Disease Distribution And Resistance In Michigan And Fungal Endophyte Ecology Of Resistant And Susceptible Beech (Fagus Grandifolia Ehrh.), Rachel E. Griesmer-Zakhar
Beech Bark Disease Distribution And Resistance In Michigan And Fungal Endophyte Ecology Of Resistant And Susceptible Beech (Fagus Grandifolia Ehrh.), Rachel E. Griesmer-Zakhar
Dissertations, Master's Theses and Master's Reports - Open
Beech bark disease (BBD), a non-native association of the fungal pathogen Neonectria faginata and the beech scale insect Cryptococcus fagisuga, has dramatically affected American beech within North American forests. To monitor the spread and effects of BBD in Michigan, a network of forest health monitoring plots was established in 2001 following the disease discovery in Ludington State Park (Mason County). Forest health canopy condition and basic forestry measurements including basal area were reassessed on beech trees in these plots in 2011 and 2012. The influence of bark-inhabiting fungal endophytes on BBD resistance was investigated by collecting cambium tissue from …

Synergistic Effects Of The Invasive Chinese Tallow (Triadica Sebifera) And Climate Change On Aquatic Amphibian Survival, Daniel Saenz, Erin M. Fucik, Matthew Kwiatkowski
Synergistic Effects Of The Invasive Chinese Tallow (Triadica Sebifera) And Climate Change On Aquatic Amphibian Survival, Daniel Saenz, Erin M. Fucik, Matthew Kwiatkowski
Faculty Publications
Changes in climate and the introduction of invasive species are two major stressors to amphibians, although little is known about the interaction between these two factors with regard to impacts on amphibians. We focused our study on an invasive tree species, the Chinese tallow (Triadica sebifera), that annually sheds its leaves and produces leaf litter that is known to negatively impact aquatic amphibian survival. The purpose of our research was to determine whether the timing of leaf fall from Chinese tallow and the timing of amphibian breeding (determined by weather) influence survival of amphibian larvae. We simulated a …

MicroRNAs (miRNAs) are 20–24 nt noncoding RNAs that play important regulatory roles in a broad range of eukaryotes by pairing with mRNAs to direct post-transcriptional repression. The mechanistic details of miRNA-mediated post-transcriptional regulation have been well documented in multicellular model organisms. However, this process remains poorly studied in algae such as Chlamydomonas reinhardtii, and specific features of miRNA biogenesis, target mRNA recognition and subsequent silencing are not well understood. In this study, we report on the characterization of a Chlamydomonas miRNA, cre-miR1174.2, , which is processed from a near-perfect hairpin RNA. Using Gaussia luciferase (gluc) reporter genes, …

Comparative Analyses Of Two Geraniaceae Transcriptomes Using Next-Generation Sequencing, Jinxin Zhang, Tracey A. Ruhlman, Jeffrey P. Mower, Robert K. Jansen
Center for Plant Science Innovation: Faculty Publications
Background: Organelle genomes of Geraniaceae exhibit several unusual evolutionary phenomena compared to other angiosperm families including accelerated nucleotide substitution rates, widespread gene loss, reduced RNA editing, and extensive genomic rearrangements. Since most organelle-encoded proteins function in multi-subunit complexes that also contain nuclear-encoded proteins, it is likely that the atypical organellar phenomena affect the evolution of nuclear genes encoding organellar proteins. To begin to unravel the complex co-evolutionary interplay between organellar and nuclear genomes in this family, we sequenced nuclear transcriptomes of two species, Geranium maderense and Pelargonium x hortorum.
Results: Normalized cDNA libraries of G. maderense and …

Mutational Analyses Of A Fork Head Associated Domain Protein, Dawdle, In Arabidopsis Thaliana, Lakshmi Ayiloor Narayanan, Dipaloke Mukherjee, Shuxin Zhang, Bin Yu, David Chevalier
Center for Plant Science Innovation: Faculty Publications
DAWDLE (DDL) gene encodes a protein that contains an N-terminal arginine-rich domain and a C-terminal Fork Head Associated (FHA) domain in Arabidopsis thaliana. DDL protein is believed to function in microRNA biogenesis by mediating the recruitment of pri-microRNA to DICER-LIKE 1 and also stabilizing the microRNA. The aim of this study was to conduct a structure-function analysis to identify the regions in DDL that are of functional significance. Targeted Induced Local Lesions in Genome screen was performed in the Columbia erecta-105 background of Arabidopsis resulting in the identification of eight point mutations spanning DDL. The mutants were characterized by …

Cdc5, A Dna Binding Protein, Positively Regulates Posttranscriptional Processing And/Or Transcription Of Primary Microrna Transcripts, Shuxin Zhang, Meng Xie, Guodong Ren, Bin Yu
Center for Plant Science Innovation: Faculty Publications
CDC5 is a MYB-related protein that exists in plants, animals, and fungi. In Arabidopsis, CDC5 regulates both growth and immunity through unknown mechanisms. Here, we show that CDC5 from Arabidopsis positively regulates the accumulation of microRNAs (miRNAs), which control many biological processes including development and adaptations to environments in plants. CDC5 interacts with both the promoters of genes encoding miRNAs (MIR) and the DNA-dependent RNA polymerase II. As a consequence, lack of CDC5 reduces the occupancy of polymerase II at MIR promoters, as well as MIR promoter activities. In addition, CDC5 is associated with the DICER–LIKE1 complex, …

Grassland habitat is declining in the northeastern United States, leading to a decline in associated native species. Consequently, there is considerable interest by land managers in conserving and restoring grassland habitats in the Northeast. However, unlike the Great Plains and Europe, quantitative monitoring of restoration sites is uncommon, making it difficult to improve new restoration projects. Here we evaluate a grassland restoration in Waterford, Connecticut to determine if mechanical clearing of woody vegetation combined with sowing 23 native grasses and forbs led to successful establishment of these species. We also compared cover, diversity, and colonization by exotic and woody species …

Crop-Friendly Bacteria Tapped To Battle Fungal Marauders, Patricia Okubara, Jan Suszkiw
Agricultural Research Magazine
Soil-dwelling bacteria that depend on wheat and barley roots for their “room and board” could soon make good on their debt. Researchers are investigating the microbes’ potential to biologically control root-rot fungi that cause crop yield losses of 10-30 percent annually in the U.S. Pacific Northwest and other parts of the world.
The bacteria are members of the genus Pseudomonas and include 11 strains that stymie the growth of Pythium and Rhizoctonia fungi, which are responsible for dampingoff and root-rot diseases of wheat and barley. The pathogens thrive in cool, moist soils and can reach especially high levels in crop …

A 2-yr study utilizing 120 mature, crossbred (Angus × Herford) cows/year, evaluated the influence of cow BCS and dried distillers grains with solubles (DDGS) supplementation during late gestation on cow performance and productivity of subsequent offspring. Treatments were arranged as a 2 × 2 factorial in a randomized complete block design with 2 BCS and with or without DDGS supplementation. Cows were nutritionally managed to enter the last trimester of gestation with a BCS of approximately 4 (LBCS) or 6 (HBCS) and were thereafter managed in a single herd (initial BCS were 4.4 and 5.7 for LBCS and HBCS treatments, …
