Abundance Of Ammonia-Oxidizing Archaea And Bacteria Along An Estuarine Salinity Gradient In Relationship To Potential Nitrification Rates, Anne E. Bernhard, Zachary C. Landry, Alison Blevins, José R. De La Torre, Anne E. Giblin, David A. Stahl

Biology Faculty Publications

Abundance of ammonia-oxidizing Archaea (AOA) was found to be always greater than that of ammonia-oxidizing Bacteria along an estuarine salinity gradient, and AOA abundance was highest at intermediate salinity. However, AOA abundance did not correlate with potential nitrification rates. This lack of correlation may be due to methodological limitations or alternative energy sources.

Assessing The Effectiveness Of The Roaring Branch Bmp Retrofit Using Macroinvertebrate Bioassessment, James L. Banning

USF Tampa Graduate Theses and Dissertations

Using benthic macroinvertebrates to measure stream health has been widely used and accepted around the world. Macroinvertebrates are resident monitors of chronic impairment in a stream since they are relatively sessile and most commonly respond to disturbance by drift but can recolonize a restored stream reach very quickly. This study tested the effectiveness of macroinvertebrate metrics developed through the Rapid Bioassessment Protocol (RBP) to detect changes in stream integrity as the result of placement of a best management practice (BMP), installed on a tributary of Roaring Branch, located in Columbus, Georgia. The BMP was designed to attenuate flow to reduce …

Estimation Of Vertical Groundwater Fluxes Into A Streambed Through Continuous Temperature Profile Monitoring And The Relationship Of Groundwater Fluxes To Coaster Brook Trout Spawning Habitat , Matthew Van Grinsven

Dissertations, Master's Theses and Master's Reports - Open

We hypothesized that the spatial distribution of groundwater inflows through river bottom sediments is a critical factor associated with the selection of coaster brook trout (a life history variant of Salvelinus fontinalis,) spawning sites. An 80-m reach of the Salmon Trout River, in the Huron Mountains of the upper peninsula of Michigan, was selected to test the hypothesis based on long-term documentation of coaster brook trout spawning at this site. Throughout this site, the river is relatively similar along its length with regard to stream channel and substrate features. A monitoring well system consisting of an array of 27 …

Highly Variable Acquisition Rates Of Ixodes Scapularis (Acari: Ixodidae) By Birds On An Atlantic Barrier Island, S. S. Mitra, P. A. Buckley, F. G. Buckley, Howard S. Ginsberg

Natural Resources Science Faculty Publications

Acquisition of ticks by bird hosts is a central process in the transmission cycles of many tick-borne zoonoses, but tick recruitment by birds has received little direct study. We documented acquisition of Ixodes scapularis Say on birds at Fire Island, NY, by removing ticks from mist-netted birds, and recording the number of ticks on birds recaptured within 4 d of release. Eight bird species acquired at least 0.8 ticks bird⁻¹ day⁻¹ during the seasonal peak for at least one age class of I. scapularis. Gray Catbirds, Eastern Towhees, Common Yellowthroats, and Northern Waterthrushes collectively accounted for 83% …

Vitamin D3, Aryeh Grossman

The Science Journal of the Lander College of Arts and Sciences

The following is the introduction of this article: Vitamin D is the only vitamin that is free. It can be easily obtained from exposure to sunlight and yet more than 60% of Americans are Vitamin D deficient (Ginde et al., 2009; Bones, Vitamin D, and Calcium, n.d). The significance of Vitamin D can’t be emphasized enough and is often overlooked. Some its profound effects are apparent in the prevention of various diseases such as cancer, multiple sclerosis, and cardiovascular disease et cetera. Many lives can be spared each year just by taking Vitamin D. From cancer alone, 23,000 deaths can …

Family Change And Poverty In Appalachia, Daniel Lichter, Lisa Cimbulak

University of Kentucky Center for Poverty Research Discussion Paper Series

The current economic and political climate provides a vivid contrast with the circumstances of the 1990s, when the passage of the 1996 Personal Responsibility and Work Opportunity Reconciliation Act (PRWORA) ushered in welfare reform during a period of unprecedented economic expansion and job growth (Blank 2002; Ziliak 2009). This legislation sought to “end the dependence of needy parents on government benefits by promoting job preparation, work, and marriage.” Among PRWORA’s goals were to reduce out-of-wedlock births and encourage the formation of two-parent families. For most states, much of the initial emphasis on self-sufficiency was placed on “work first” programs (i.e., …

Predator Effects In Predator-Free Space: The Remote Effects Of Predators On Prey, John L. Orrock, Lawerence M. Dill, Andrew Sih, Johnathan H. Grabowski, Scott D. Peacor, Barbara L. Peckarsky, Evan L. Preisser, James R. Vonesh, Earl E. Werner

Biological Sciences Faculty Publications

Predators can have remote effects on prey populations that are connected by migration (i.e. prey metapopulations) because predator-mediated changes in prey behavior and abundance effectively transmit the impact of predators into predator-free prey populations. Behavioral changes in prey that might give rise to remote effects are altered rates of migration or activity in the presence of predation risk (called non-consumptive effects, fear- or μ-driven effects, and risk effects). Changes in prey abundance that may result in remote effects arise from changes in prey density due to direct predation (i.e. consumptive effects, also called N-driven effects and predation effects). Remote effects …

Ecological Boundary Detection Using Bayesian Areal Wombling, Matthew C. Fitzpatrick, Evan L. Preisser, Adam Porter, Joseph Elkinton, Lance A. Waller, Bradley P. Carlin, Aaron M. Ellison

Biological Sciences Faculty Publications

The study of ecological boundaries and their dynamics is of fundamental importance to much of ecology, biogeography, and evolution. Over the past two decades, boundary analysis (of which wombling is a subfield) has received considerable research attention, resulting in multiple approaches for the quantification of ecological boundaries. Nonetheless, few methods have been developed that can simultaneously (1) analyze spatially homogenized data sets (i.e., areal data in the form of polygons rather than point‐reference data); (2) account for spatial structure in these data and uncertainty associated with them; and (3) objectively assign probabilities to boundaries once detected. Here we describe the …

Interspecific Variation In Palatability Suggests Cospecialization Of Antipredator Defenses In Sea Hares, Kimberly K. Takagi, Nadia N. Ono, William G. Wright

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Prey species often deploy different kinds of antipredator defenses, which can interact with each other in ways that are not yet completely understood. Much research into these interactions has utilized gastropod mollusks, usually focusing (in part) on the protective utility of the gastropod shell. This makes the evolutionary reduction of the shell in the opisthobranch gastropods (marine slugs) particularly interesting. This loss of protective function of the shell is associated with the evolution of alternative defenses. Particularly well studied are chemical defenses, especially those using secondary metabolites derived from food resources. As a first step toward understanding interspecific variation in …

A Second Dimension To The Leaf Economics Spectrum Predicts Edaphic Habitat Association In A Tropical Forest, Jennifer L. Baltzer, Sean C. Thomas

Biology Faculty Publications

Background: Strong patterns of habitat association are frequent among tropical forest trees and contribute to the maintenance of biodiversity. The relation of edaphic differentiation to tradeoffs among leaf functional traits is less clear, but may provide insights into mechanisms of habitat partitioning in these species rich assemblages.

Methodology/Principal Findings: We quantify the leaf economics spectrum (LES) for 16 tree species within a Bornean forest characterized by highly pronounced habitat specialization. Our findings suggest that the primary axis of trait variation in light-limited, lowland tropical forests was identical to the LES and corresponds with the shade tolerance continuum. There was no …

What Is The Taxonomic Identity Of Minnesota Wolves?, L. David Mech

United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

The taxonomic identity of the historical and current wolf (Canis lupus L., 1758 or Canis lycaon Schreber, 1775 or their hybrids) population in Minnesota (MN) and the Great Lakes region has been, and continues to be, controversial. So too does its legal status under the U.S. Endangered Species Act. This review summarizes the morphological and genetic information about that population and concludes that historically the MN population consisted of a gray wolf (C. lupus) in the west and an eastern type (Canis lupus lycaon or C. lycaon) in the east with intergrades or hybrids between …

Liana Host Preference And Implications For Deciduous Forest Regeneration, Laura M. Ladwig, Scott J. Meiners

Faculty Research & Creative Activity

Lianas have the potential to shape forest communities and alter forest regeneration. However, impacts of lianas on forest regeneration, particularly in temperate forests, are largely unstudied. To understand potential liana impacts on the community we need to first know the location and intensity of liana burdens on host trees. We examined liana-tree host references within a series of young regenerating deciduous forests in the Piedmont region of New Jersey, USA. Established trees ($ 5 cm dbh) and the lianas associated with each tree were surveyed in 2008. The five most abundant liana species were Celastrus orbiculatus, Lonicera japonica, Parthenocissus quinquefolia, …

Post-­Fire Alterations In Mechanical Strength Of Leaves In Heteromeles Arbutifolia, Andrew Hair, Madeline Dilascia, Nick Novella, Taylor Wurdeman

Featured Research

Wildfires in the Santa Monica mountains in Southern California burn down a decent percentage of the local vegetation. However, some plants like Heteromeles Arbutifolia, are considered to be resprouters because they return a mere two years after being burnt down. It is hypothesized that the artificially browsed resprout leaves will have a lower tensile strength than both the young and adult leaves because they use a lower amount of carbohydrates per unit-leaf-area. Data showed that although there was a slight different between the young leaves and the adult leaves of the Heteromeles, there was no statistically significant difference between the …
