Decreased Reproductive Investment Of Female Threespine Stickleback Gasterosteus Aculeatus Infected With The Cestode Schistocephalus Solidus: Parasite Adaptation, Host Adaptation, Or Side Effect?, Eric T. Schultz, Michelle Topper, David C. Heins

EEB Articles

Parasitic infections may cause alterations in host life history, including changes in reproductive investment (absolute amount of energy allocated to reproduction) and reproductive effort (proportion of available energy allocated to reproduction). Such changes in host life history may reflect: 1) a parasite tactic: the parasite adaptively manipulates energy flow within the host so that the host is induced to make a reduction in reproductive effort and reproductive investment, making more energy available to the parasite; 2) no tactic: there is no change in host reproductive effort and reproductive investment simply decreases as a side effect of the parasite depleting host …

Prevalence And Serovars Of Salmonella In The Feces Of Free-Ranging White-Tailed Deer (Odocoileus Virginianus) In Nebraska, David G. Renter, David P. Gnad, Jan M. Sargeant, Scott E. Hygnstrom

School of Natural Resources: Faculty Publications

To determine the prevalence and serovars of Salmonella in free-ranging deer, we cultured feces from white-tailed deer (Odocoileus virginianus) harvested by hunters during a regular firearm season in southeastern Nebraska (USA). We recovered Salmonella from 5 (1%; 95% confidence interval: 0.37– 2.20%) of 500 samples and identified four different Salmonella enterica serovars [Litchfield (1), Dessau (1), Infantis (2), and Enteritidis (1)]. Although the prevalence of Salmonella in free-ranging deer appears to be low, the serovars recovered are known to be pathogenic to humans and animals.

“Nuisance” Wildlife Control Trapping: Another Perspective, Brad Gates, John Hadidian, Laura Simon

Wildlife Population Management Collection

Urban wildlife control is a rapidly growing profession in which many practitioners apparently still come from a recreational or commercial trapping background. Perhaps for that reason, much of the “control” in resolving human-wildlife conflicts in cities and suburbs seems to revolve around the use of lethal traps to eliminate “problem” animals. Although some states allow relocation and most apparently allow for nuisance animals to be released on site, the extent to which these practices occur is little known. Further, the biological impacts of continual trapping cycles on urban wildlife populations remain little known as well. An alternative approach to trapping …

Behaviour Development: A Cephalopod Perspective, Jennifer A. Mather

Interactive Behavior Collection

This paper evaluates the development of behaviour from the viewpoint of the intelligent and learningdependent cephalopod mollusks as a contrast to that of mammals. They have a short lifespan, commonly one to two years, and most are semelparous, reproducing only near the end of their lifespan. In the first two months of life, Sepia officinalis cuttlefish show drastic limitation on learning of prey choice and capture, gradually acquiring first short-term and then long-term learning over 60 days. This is paralleled by development of the vertical lobe of the brain which processes visually learned information. In the long nonreproductive adulthood, Octopus …

Invasion Of Exotic Earthworms Into Ecosystems Inhabited By Native Earthworms, P. F. Hendrix, G. H. Baker, M. A. Callaham Jr., G. A. Damoff, C. Fragoso, G. Gonzalez, S. W. James, S. L. Lachnicht, T. Winsome, X. Zou

Faculty Publications

The most conspicuous biological invasions in terrestrial ecosystems have been by exotic plants, insects and vertebrates. Invasions by exotic earthworms, although not as well studied, may be increasing with global commerce in agriculture, waste management and bioremediation. A number of cases has documented where invasive earthworms have caused significant changes in soil profiles, nutrient and organic matter dynamics, other soil organisms or plant communities. Most of these cases are in areas that have been disturbed (e.g., agricultural systems) or were previously devoid of earthworms (e.g., north of Pleistocene glacial margins). It is not clear that such effects are common in …

Social Play In Kakapo (Strigops Habroptilus) With Comparisons To Kea (Nestor Notabilis) And Kaka (Nestor Meridionalis), Judy Diamond, Daryl Eason, Clio Reid, Alan B. Bond

Papers in Behavior in Biological Sciences

The play behavior of the critically endangered kakapo (Strigops habroptilus; Aves: Psittaciformes: Psittacidae) is here compared to that of its closest relatives, the kea (Nestor notabilis) and the kaka (Nestor meridionalis). Contrasting kakapos, which are relatively solitary, with the more social Nestor parrots provides an attractive test of the relative contributions of phylogeny and sociality to the evolution of play. Overlapping cluster analysis of play sequences using a hypergeometric similarity metric indicated that kakapo play is generally less complex, lacking the intensity, duration, structure, and reciprocity of play in the Nestor parrots. Kakapos have …

Acorn Use As Food, David A. Bainbridge

David A Bainbridge

The acorns from oaks (Quercus) and tan oaks (Lithocarpus) have been used as food for many thousands of years. They occur in the archaeological record of the early town sites in the Zagros Mountains, at Catal Hüyük (6000 BC), and oak trees were carefully inventoried by the Assyrians during the reign of Sargon II. In Europe, Asia, North Africa, the Mid-East, and North America, acorns were once a staple food. They are still a commercial food crop in several countries. Acorns are still harvested and used in several areas of the United States, most notably Southern Arizona and California. There …

Comparative Efficiency Of Six Stable Fly Traps., David B. Taylor, Dennis R. Berkebile

David B Taylor

Five adhesive traps and the Nzi cloth-target trap were compared to determine their trapping efficiency and biases for stable flies, Stomoxys calcitrans (L.) (Diptera: Muscidae). Two confgurations of the BiteFree prototype trap, constructed of polyethylene terephthalate, were most efficient for trapping stable flies, whereas the EZ trap was least efficient. The two Alsynite traps, Broce and Olson, were intermediate to the BiteFree prototype and EZ traps. All adhesive traps collected a ratio of approximately two males for each female. Approximately 50% of the flies collected on the adhesive traps, both male and female, were blood fed, and 20% were vitellogenic. …

On The Robustness Of Robustness Checks Of The Environmental Kuznets Curve, Marzio Galeotti, Matteo Manera, Alessandro Lanza

Matteo Manera

Since its first inception in the debate on the relationship between environment and growth in 1992, the Environmental Kuznets Curve has been subject of continuous and intense scrutiny. The literature can be roughly divided in two historical phases. Initially, after the seminal contributions, additional work aimed to extend the investigation to new pollutants and to verify the existence of an inverted-U shape as well as assessing the value of the turning point. The following phase focused instead on the robustness of the empirical relationship, particularly with respect to the omission of relevant explanatory variables other than GDP, alternative datasets, functional …

Our Places To Tell Stories: Making Connections With Our Audiences, Public Lands Institute

Our Places to Tell Stories

The idea for an annual Our Places Tell Stories conference was prompted by discussions that took place within a unique partnership of federal, state, university, and public organizations in southern Nevada. Members identified the need to share and learn from successful educational and interpretive strategies. Our increasingly urban surroundings and rapidly changing populations hinder personal connections between people and their natural environment. However, the right tools and techniques will help us inspire children and adults to understand, value, and take care of our shared natural places.

This first conference supports professionals in creating and evaluating effective educational programs and interpretive …

The Breeding Ecology And Natural History Of Ambystomatid Salamanders In An Ephemeral Wetland In Mason County, West Virginia, S. Douglas Kaylor

Theses, Dissertations and Capstones

A forested ephemeral wetland in Mason County, WV, documented to contain 4 of 5 Ambystoma species found in the state, was studied to learn about population sizes, breeding cycles, and habitat use. Minnow traps were placed along three drift fences with additional traps placed throughout the study area. From February 5 to March 27, 2005, 85 captured adults were identified to species, marked by elastomer injection for mark-recapture analysis, and measured for morphometrics. Larval salamanders were identified, staged, measured, and returned. Egg clutches were mapped and counted. Mark-recapture analysis suggests the A. texanum population size is between 635 and 735 …
