Food Habits Of The Hoary Bat In An Agricultural Landscape, Mathew K. Perlik, Brock R. Mcmillan, John D. Krenz

Journal of the Minnesota Academy of Science

Information on diets is fundamental to ecological studies. Prey use by the solitary, tree-roosting hoary bat (Lasiurus cinereus) in agricultural landscapes is not known. We examined the stomach contents and fecal material from carcasses of hoary bats collected during a mortality study at wind turbine sites in southwestern Minnesota. We compared diet of hoary bats to availability of prey to determine whether bats were opportunistic or selective. Food of the hoary bats primarily consisted of lepidopterans (moths; 49-50 %) and coleopterans (beetles; 28-40 %). The abundance of insects in the diet of hoary bats was not proportional to the estimated …

Spread Of White-Nose Syndrome On A Network Regulated By Geography And Climate, Sean P. Maher, Andrew M. Kramer, J. Tomlin Pulliam, Marcus A. Zokan, Sarah E. Bowden, Heather D. Barton, Krisztian Magori, John M. Drake

College of Natural and Applied Sciences

Wildlife and plant diseases can reduce biodiversity, disrupt ecosystem services and threaten human health. Emerging pathogens have displayed a variety of spatial spread patterns due to differences in host ecology, including diffusive spread from an epicentre (West Nile virus), jump dispersal on a network (foot-and-mouth disease), or a combination of these (Sudden oak death). White-nose syndrome is a highly pathogenic infectious disease of bats currently spreading across North America. Understanding how bat ecology influences this spread is crucial to management of infected and vulnerable populations. Here we show that white-nose syndrome spread is not diffusive but rather mediated by patchily …

Interspecific Variation In Temperature Effects On Embryonic Metabolism And Development In Turtles, Day B. Ligon, M. B. Lovern

College of Natural and Applied Sciences

We measured temperature-induced differences in metabolic rates and growth by embryos of three turtle species, Macrochelys temminckii, Trachemys scripta, and Apalone spinifera, at different, constant, temperatures. Oxygen consumption rate (VO2) was measured during development and used to characterize changes in metabolism and calculate total O2 consumption. Results from eggs incubated at different temperatures were used to calculate Q10s at different stages of development and to look for evidence of metabolic compensation. Total O2 consumption over the course of incubation was lowest at high incubation temperatures, and late-term metabolic rate Q10s were <2 in all three species. Both results were consistent with positive metabolic compensation. However, incubation temperature effects on egg mass-corrected hatchling size varied among species. Apalone spinifera hatchling mass was unaffected by temperature, whereas T. scripta mass was greatest at high temperatures and M. temminckii mass was lowest at high temperatures. Hatchling mass : length relationships tended to correlate negatively with temperature in all three species. Although we cannot reject positive metabolic compensation as a contributor to the observed VO2 patterns, there is precedence for drawing the more parsimonious conclusion that differences in yolk-free size alone produced the observed incubation temperature differences without energetic canalization by temperature acclimation during incubation.

Dendrimers Bind Antioxidant Polyphenols And Cis-Platin Drug, Amine Abderrezak, Philippe Bourassa, Jean-Sebastian Mandeville, Reza Sedaghat-Herati, Heidar-Ali Tajmir-Riahi

College of Natural and Applied Sciences

Synthetic polymers of a specific shape and size play major role in drug delivery systems. Dendrimers are unique synthetic macromolecules of nanometer dimensions with a highly branched structure and globular shape with potential applications in gene and drug delivery. We examine the interaction of several dendrimers of different compositions mPEG-PAMAM (G3), mPEG-PAMAM (G4) and PAMAM (G4) with hydrophilic and hydrophobic drugs cisplatin, resveratrol, genistein and curcumin at physiological conditions. FTIR and UV-visible spectroscopic methods as well as molecular modeling were used to analyse drug binding mode, the binding constant and the effects of drug complexation on dendrimer stability and conformation. …

Moss Cell Walls: Structure And Biosynthesis, Alison W. Roberts, Eric M. Roberts, Candace H. Haigler

Biological Sciences Faculty Publications

The genome sequence of the moss Physcomitrella patens has stimulated new research examining the cell wall polysaccharides of mosses and the glycosyl transferases that synthesize them as a means to understand fundamental processes of cell wall biosynthesis and plant cell wall evolution. The cell walls of mosses and vascular plants are composed of the same classes of polysaccharides, but with differences in side chain composition and structure. Similarly, the genomes of P. patens and angiosperms encode the same families of cell wall glycosyl transferases, yet, in many cases these families have diversified independently in each lineage. Our understanding of land …

Status Of Reintroduced American Marten In The Manistee National Forest Within Michigan’S Northern Lower Peninsula, Julie M. Watkins

McNair Scholars Journal

American martens (Martes americana) were extirpated from the Lower Peninsula of Michigan as a result of overharvest for fur and habitat loss in the early 1900s. More sustainable logging practices, forest regeneration, and improved understanding of wildlife habitat requirements, subsequently led to suitable marten habitat restoration within the Lower Peninsula. In the mid- 1980s in an attempt to re-establish a viable population in the Northern Lower Peninsula, 36 martens were reintroduced into the Manistee National Forest (MNF). In the 2011 summer field season we conducted a pilot study investigating the genetic structure of populations in Ward Hills and Caberfae in …

Individual Contexts Versus Group Contexts, Thomas Ewing

McNair Scholars Journal

Our research is aimed at better understanding when and why people gravitate toward groups and whether people act differently in groups versus being alone. Past research has shown that groups provide people with a sense of anonymity and diffusion of responsibility (Hirsh, Galinsky, & Zhong, 2011). For instance, when people are in groups, they feel they are less identifiable and when part of a group, people feel less personally accountable when actions go awry. Because people feel less accountable, and because groups are less likely to be targeted than individuals, groups also provide a sense of psychological safety (Park & …

History Of Emotional And Physical Abuse And Parenting, Mayra Sanchez

McNair Scholars Journal

Childhood abuse is a social problem that is associated with many negative outcomes later in life such as an increased risk for suicide attempts, depression, and problems with communication skills. Because physical and emotional abuse is significantly correlated, it is often difficult to determine the impact of the physical versus emotional aspects of the maltreatment. Thus, this study explored the extent to which physical and emotional abuse is each associated with parenting attitudes, disciplinary choices, and risk for later abusive parenting. This study also assessed the extent to which deficits in parental empathy that may result from having had a …

Casuarina Root Exudates Alter The Physiology, Surface Properties, And Plant Infectivity Of Frankia Sp. Strain Cci3, Nicholas J. Beauchemin, Teal Furnholm, Julien Lavenus, Sergio Svistoonoff, Patrick Doumas, Didier Bogusz, Laurent Laplaze, Louis S. Tisa

Molecular, Cellular & Biomedical Sciences

The actinomycete genus Frankia forms nitrogen-fixing symbioses with 8 different families of actinorhizal plants, representing more than 200 different species. Very little is known about the initial molecular interactions between Frankia and host plants in the rhizosphere. Root exudates are important in Rhizobium-legume symbiosis, especially for initiating Nod factor synthesis. We measured differences in Frankia physiology after exposure to host aqueous root exudates to assess their effects on actinorhizal symbioses. Casuarina cunninghamiana root exudates were collected from plants under nitrogen-sufficient and -deficient conditions and tested on Frankia sp. strain CcI3. Root exudates increased the growth yield of Frankia in the …

Revisiting Maine’S Lobster Commons: Rescaling Political Subjects, Jennifer F. Brewer

Geography

Calls for cross-scalar theoretical and methodological approaches are not new to commons scholarship. Such efforts might be hastened by channelling poststructuralist and critical theory perspectives through the geographic subfield of political ecology, including attention to political scales and subjects. Toward this end, this paper reconsiders Maine’s lobster fishery. This case has provided rich material for watershed commons scholarship, demonstrating the ability of social groups to conserve resources independent of government or markets, and it continues to offer new findings. Recent fieldwork shows that as lobster boat captains advance collective interests through state-supported co-management governance arrangements, concerns of crew and non-fishing …

Is It Time To Forget Science? Reflections On Singular Science And Its History, Jan V. Golinski

History

The name history of science refl ects a set of assumptions about what science is. Among them is the claim that science is a singular thing, a potentially unifi ed group of disciplines that share a common identity. Long promoted by scientists and philosophers on the basis of a supposedly universal scientifi c method, this claim now looks very embattled. I trace its development from the early nineteenth century and the growth of the positivist movement to its various manifestations in the twentieth century. Recently, some historians have called for the term science to be relinquished, and for adoption of …
