The Relationship Of Stomatal Conductnace To Mechanical Strength In Leaves Of Santa Monica Plants, Russell P. Mott, Steven R. Fleming, John R. Macbeth

Featured Research

The Santa Monica Mountains ecosystem has a high diversity of plants with different lifestyles that produce different physiological characteristics individual to all plants. Studies in Australia, another Mediterranean ecosystem, have shown that mechanical strength of leaves is relatable to soil stress. This experiment seeks to determine whether mechanical strengths of leaves correlate to stomatal conductance of leaves across different species in the Santa Monica Mountains. Four species of plants are tested for their stomatal conductance in the field, and the leaves are tested for tensile strength using Young’s Modulus for comparison across leaves. These data show that there was no …

Stomatal Conductance Trends Of The Jade Plant (Crassula Ovata) In Relation To Circadian Rhythm Entrainability, Katie Cahoon, Martin Garcia, Matthew Pierga

Featured Research

The effect of an inverse light cycle on a Crassulacean acid metabolism (CAM) plant was observed in the study. CAM plants are unique in that they open their stomata at night in order to conserve water, an evolution that has come about because these plants primarily exist in very arid climates. By placing a plant in a chamber in which the lights could be programmed to turn on when it was dark out, and to turn off during normal daylight hours, the stomatal conductance of the leaves of a jade plant (Crassula ovata) were recorded several times a day over …

The Effect Of Dirt On Inhibition Of Light Absorption In Musa Leaves, Lorelle Knight, Alexis Carrington, Angela French, Roxanne Barker

Featured Research

Dirt can be transported by wind, human activity and many other factors. It was hypothesized that dirt particles collected on leaves will decrease leaf reflectance and thus make the leaf less healthy. The rationale for this is that the more dirt present on the leaf, the more inhibited photons will be in reaching leaf pigments. The leaf will therefore be less healthy as it will be less able to perform photosynthesis. To test this hypothesis, eight leaf samples with varying amounts of dirt present, were collected from the plant, Musa. A Unispec spectrophotometer was used to test the reflectance of …

The Effect Of Riparian And Arid Environments On Stomatal Conductance In Baccharis Salicifolia And Heteromeles Arbutifolia, Danalit Rangel, Vicki Mac, Ariel Lan

Featured Research

A riparian environment is characterized by higher moisture levels than an arid environment; therefore they have different species of plants that can adapt to their natural habitats. It is critical that we explore the characteristics plants have in relation to their native environments. We propose to test the hypothesis that Baccharis salicifolia would have a higher stomatal conductance rate to water vapor loss compared to Heteromeles arbutifolia because Baccharis salicifolia thrives in a riparian environment in which water abundance would increase stomatal opening thereby contributing to the greater conductance. Using the LI-6400, we measured the conductance rate, photosynthetic rate, CO2 …

A Comparison Of Brittlebush (Encelia Farinosa) Productivity And Health During Drought And Post Rainfall, Gabi Diciolli, Karre Lawson, Anders Reimer

Featured Research

Encelia farinosa is well adapted for drought tolerance as its leaves transform color based on water availability. We were puzzled by a question that any desert botanist must consider. How does the photosynthetic efficiency of E. farinosa fluctuate as it transitions from a state of drought to a state of soil saturation within a 72 hour period? In this experiment we looked at the effects of irrigation on the health and quantum yield of the brittlebush by looking at photosynthetic rates using the portable photosynthesis system LI-COR 6400 when applied to two leaves on a given plant and water potential …

Troublesome Concepts And Information Literacy: Investigating Threshold Concepts For Il Instruction, Amy R. Hofer, Lori Townsend, Korey Brunetti

Library Faculty and Staff Publications and Presentations

Librarians regularly encounter students who struggle to understand and apply information literacy concepts. A qualitative survey administered to information literacy practitioners asked about troublesome content and analyzed results using the threshold concepts pedagogical framework first described by Jan Meyer and Ray Land. A threshold concept transforms the learner’s view of content and helps integrate previously learned material; threshold concepts are portals that, once traversed, bring insight into how to think and act like a practitioner within a discipline. This project uses the data collected to propose seven threshold concepts for information literacy.

The Quantitative Soil Pit Method For Measuring Belowground Carbon And Nitrogen Stocks, Matthew A. Vadeboncoeur, Steven P. Hamburg, Joel D. Blum, Michael J. Pennino, Ruth D. Yanai, Chris E. Johnson

All Materials

Many important questions in ecosystem science require estimates of stocks of soil C and nutrients. Quantitative soil pits provide direct measurements of total soil mass and elemental content in depth-based samples representative of large volumes, bypassing potential errors associated with independently measuring soil bulk density, rock volume, and elemental concentrations. The method also allows relatively unbiased sampling of other belowground C and nutrient stocks, including roots, coarse organic fragments, and rocks. We present a comprehensive methodology for sampling these pools with quantitative pits and assess their accuracy, precision, effort, and sampling intensity as compared to other methods. At 14 forested …

Light And Vision In The Deep-Sea Benthos: I. Bioluminescence At 500-1000 M Depth In The Bahamian Islands, Sönke Johnsen, Tamara M. Frank, Steven H.D. Haddock, Edith A. Widder, Charles G. Messing

Marine & Environmental Sciences Faculty Articles

Bioluminescence is common and well studied in mesopelagic species. However, the extent of bioluminescence in benthic sites of similar depths is far less studied, although the relatively large eyes of benthic fish, crustaceans and cephalopods at bathyal depths suggest the presence of significant biogenic light. Using the Johnson-Sea-Link submersible, we collected numerous species of cnidarians, echinoderms, crustaceans, cephalopods and sponges, as well as one annelid from three sites in the northern Bahamas (500–1000 m depth). Using mechanical and chemical stimulation, we tested the collected species for light emission, and photographed and measured the spectra of the emitted light. In addition, …

Development And Characterization Of 11 Novel Microsatellite Loci For The Roundscale Spearfish Tetrapturus Georgii And Their Cross-Species Amplification Among Other Istiophorid Species, Andrea M. Bernard, Kevin A. Feldheim, Mahmood S. Shivji

Marine & Environmental Sciences Faculty Articles

Eleven novel polymorphic microsatellite loci were developed and characterized for the recently validated roundscale spearfish Tetrapturus georgii. Characterization of these markers, based on 35 roundscale spearfish from the western North Atlantic, revealed two to 21 alleles per locus with an average expected heterozygosity (HE) of 0·09–0·94, and all loci conformed to Hardy–Weinberg expectations. Cross-amplification of these 11 loci against all other eight known istiophorid species indicates promising prospects for the utility of these markers for istiophorids in general.

Exploratory Modeling Indicates Red-Backed Salamander Detections Are Sensitive To Soil Ph At C. F. Phelps Wildlife Management Area, Virginia, Jay D. Mcghee, Michael D. Killian

Virginia Journal of Science

Red-backed salamanders represent an important component of Virginia ecosystems, but there are few habitat models that can reliably predict the presence/absence of this species. We surveyed the habitats of red-backed salamanders at one site in the Piedmont region of Virginia and collected data on an array of habitat variables with which this species is normally associated. We used logistic regression to develop a model predicting the presence or absence of the species at a given 50m-transect. Our final model incorporated soil organic layer pH variability and mineral layer average pH, and accounted for 30% of the variation in our data. …

Chronic Child Neglect: Cys Staff Perspectives On Repeat Clients, Erin M. Murphy

Capstone Collection

Since the late 1960‘s, child protection agencies have acted under federal mandate to intervene in cases of child abuse and neglect. In accordance with state child protection laws, these agencies provide monitoring and support services to "at-risk" families. Despite these efforts, studies have shown that a record number of parents who receive services are re-reported to the agency for additional offenses within a short period of time. The available literature attributes recidivism to delayed or mismanaged interventions and adverse socio-economic conditions among parents, but research that considers employee perspectives on chronic neglect is scant. This paper explores inter and extra-agency …

Seeking Liberty’S Refuge: Analyzing Legislative Purpose Under Casey’S Undue Burden Standard, Lucy E. Hill

Fordham Law Review

   In the 1992 decision Planned Parenthood of Southeastern Pennsylvania v. Casey, the U.S. Supreme Court crafted the “undue burden” standard for evaluating the constitutionality of abortion laws. Under that standard, a state is free to regulate abortion, as long as the regulation does not impose an undue burden on a woman’s right to an abortion. Although the standard is disjunctive, the Casey opinion focuses on the “effect” prong of the test, with little guidance as to what a “purpose” prong inquiry would look like. Subsequent Supreme Court abortion jurisprudence has served only to obscure the issue. Circuit courts, therefore, …

Cdk Inhibitors (P16/P19/P21) Induce Senescence And Autophagy In Cancer-Associated Fibroblasts, "Fueling" Tumor Growth Via Paracrine Interactions, Without An Increase In Neo-Angiogenesis., Claudia Capparelli, Barbara Chiavarina, Diana Whitaker-Menezes, Timothy G Pestell, Richard Pestell, James Hulit, Sebastiano Andò, Anthony Howell, Ubaldo E. Martinez-Outshoorn, Federica Sotgia, Michael P. Lisanti

Here, we investigated the compartment-specific role of cell cycle arrest and senescence in breast cancer tumor growth. For this purpose, we generated a number of hTERT-immortalized senescent fibroblast cell lines overexpressing CDK inhibitors, such as p16(INK4A), p19(ARF) or p21(WAF1/CIP1). Interestingly, all these senescent fibroblast cell lines showed evidence of increased susceptibility toward the induction of autophagy (either at baseline or after starvation), as well as significant mitochondrial dysfunction. Most importantly, these senescent fibroblasts also dramatically promoted tumor growth (up to ~2-fold), without any comparable increases in tumor angiogenesis. Conversely, we generated human breast cancer cells (MDA-MB-231 cells) overexpressing CDK inhibitors, …
