Fitchburg, MA, United States

Fitchburg State University, also called Fitchburg State, is a four-year public institution of higher learning with a compact urban campus, in the city of Fitchburg, Massachusetts, United States. Fitchburg State University has over 3,500 undergraduate and over 1650 graduate/continuing education students, for a total student body enrollment over 5200. The College offers postgraduate certificates, bachelor's degrees, and master's degrees in more than 25 academic disciplines. The main campus, the McKay Campus School, and athletic fields occupy 79 acres in the city of Fitchburg; the biological study fields occupy 120 acres in the neighboring towns of Lancaster, Leominster, and Lunenburg.

Aquatic herbicides are applied to control nuisance vegetation in lakes and ponds, and are often re-applied over many years. This study compared the abundance of 5 frog species in treated and untreated lakes in Ashburnham, MA. At each lake, I assessed the density of human housing and lake area to determine their relationship with frog abundance. I employed a standard calling index to estimate the abundance of each frog species and the sum of calling indices from all species served as a measure of total frog abundance at each survey site. The sum of calling indices declined with increasing density of human housing; herbicide treatment was not an important main effect. However, there was marginal interaction between herbicides and housing density: lakes with moderate-high housing densities seemed to have lower frog abundance with herbicide treatments. Although the data set was limited, my results suggest that frogs may benefit from permanently untreated refuge zones on lakes. When I assessed frog species individually, only Rana clamitans (Green Frog) was less common as housing density increased. None of the 5 frog species were less abundant in herbicide-treated lakes. In my study, long-term use of aquatic herbicides did not generally reduce abundance of adult frogs, but more studies may be needed to determine whether some herbicides may impair frog populations that are already stressed by housing development.

In today's template-driven environment of website design it is a challenge to teach students the concept of metaphor production for visual interfaces and inspire them to explore the inherent creative potential of screen-based media. This poster showcases student work from an introductory web design course project created to encourage students to think of a web space, interface, and typography in terms of metaphor. To this end, students produced small websites using text from Italo Calvino's Invisible Cities in efforts to form visual metaphors of the text's content based on their own novel subjective interpretations. The value of this assignment is in its alternative approach to teaching introductory web and interface design. © 2016 Copyright held by the owner/author(s). Source

Plant responses to insects and wounding involve substantial transcriptional reprogramming that integrates hormonal, metabolic, and physiological events. The ability to respond differentially to various stresses, including wounding, generally involves hormone signaling and trans-acting regulatory factors. Evidence of the importance of transcription factors (TFs) in responses to insects is also accumulating. However, the relationships among hormone signaling, TF activity, and ability to respond specifically to different insects are uncertain. We examined transcriptional and hormonal changes in Arabidopsis thaliana after herbivory by larvae of two lepidopteran species, Spodoptera exigua (Hübner) and Pieris rapae L. over a 24-h time course. Transcriptional responses to the two insects differed and were frequently weaker or absent in response to the specialist P. rapae. Using microarray analysis and qRT-PCR, we found 141 TFs, including many AP2/ERFs (Ethylene Response Factors) and selected defense-related genes, to be differentially regulated in response to the two insect species or wounding. Jasmonic Acid (JA), JA-isoleucine (JA-IL), and ethylene production by Arabidopsis plants increased after attack by both insect species. However, the amounts and timing of ethylene production differed between the two herbivory treatments. Our results support the hypothesis that the different responses to these two insects involve modifications of JA-signaling events and activation of different subsets of ERF TFs, resulting in different degrees of divergence from responses to wounding alone. © 2014 Rehrig, Appel, Jones and Schultz.

Cell Death and Differentiation | Year: 2011

In most multicellular organisms, the decision to undergo programmed cell death in response to cellular damage or developmental cues is typically transmitted through mitochondria. It has been suggested that an exception is the apoptotic pathway of Drosophila melanogaster, in which the role of mitochondria remains unclear. Although IAP antagonists in Drosophila such as Reaper, Hid and Grim may induce cell death without mitochondrial membrane permeabilization, it is surprising that all three localize to mitochondria. Moreover, induction of Reaper and Hid appears to result in mitochondrial fragmentation during Drosophila cell death. Most importantly, disruption of mitochondrial fission can inhibit Reaper and Hid-induced cell death, suggesting that alterations in mitochondrial dynamics can modulate cell death in fly cells. We report here that Drosophila Reaper can induce mitochondrial fragmentation by binding to and inhibiting the pro-fusion protein MFN2 and its Drosophila counterpart dMFN/Marf. Our in vitro and in vivo analyses reveal that dMFN overexpression can inhibit cell death induced by Reaper or γ-irradiation. In addition, knockdown of dMFN causes a striking loss of adult wing tissue and significant apoptosis in the developing wing discs. Our findings are consistent with a growing body of work describing a role for mitochondrial fission and fusion machinery in the decision of cells to die. © 2011 Macmillan Publishers Limited All rights reserved.

Understanding group activities is an essential step towards studying complex crowd behaviours in video. However, such research is often hampered by the lack of a formal definition of a group, as well as a dearth of datasets that concentrate specifically on Atomic Group Actions. 1 In this paper, we provide a quantitative definition of a group based on the Group Transition Ratio (Gtr); the Gtr helps determine when individuals transition to becoming a group (where the individuals can still be tracked) or a crowd (where tracking of individuals is lost). In addition, we introduce the Atomic Group Actions Dataset, a set of 200 videos that concentrate on the atomic group actions of objects in video, namely the group-group actions of formation, dispersal, and movement of a group, as well as the group-person actions of person joining and person leaving a group. We further incorporate a structured, end-to-end analysis methodology, based on workflows, to easily and automatically allow for standardized testing of new group action models against this dataset. We demonstrate the efficacy of the Gtr on the Atomic Group Actions Dataset and make the full dataset (the videos, along with their associated tracks and ground truth, and the exported workflows) publicly available to the research community for free use and extension at at http://research. sethi.org/ricky/datasets/. © 2015 IEEE.
