A Northward Range Extension Of The Hispid Cotton Rat (Sigmodon Hispidus) In Missouri, Cody W. Thompson, Elmer J. Finck Dec 2013

A Northward Range Extension Of The Hispid Cotton Rat (Sigmodon Hispidus) In Missouri, Cody W. Thompson, Elmer J. Finck

The Prairie Naturalist

The hispid cotton rat (Sigmodon hispidus) is a widely distributed rodent with a geographic range extending from north-central Mexico to southern Nebraska and central Virginia and from southeastern Arizona east to Florida (Carleton et al. 1999, Peppers and Bradley 2000, Wilson and Reeder 2005) with isolated populations in Arizona (Bradley et al. 2012) and California (Clark 1972). Range expansions for the species have been well documented (Clark 1972, Farney 1975, Benedict et al. 2000, Wright et al. 2010, Wills et al. 2011). The majority of these range expansions have occurred across the Central Plains during the 20th century …


The Envenoming Pandemic And The Misguided Views Of Snakes: Developing Sustainable Relationships Between Native Poisonous Snakes Of India And The Citizens Of Maharashtra Through The Use Of The Irula Model., Destiny Villanueva Nov 2013

The Envenoming Pandemic And The Misguided Views Of Snakes: Developing Sustainable Relationships Between Native Poisonous Snakes Of India And The Citizens Of Maharashtra Through The Use Of The Irula Model., Destiny Villanueva

Animal Science

Due to its vast population and general negative consensus regarding snakes, India is notorious for having more snakebite incidents than any other country. Snakes are simultaneously revered and feared in Indian religion and culture. This stigma is perpetuated through propaganda, family beliefs, and innate fears of snakes.These stigmas are more pronounced within rural areas, such as the region of Mahad within the state of Maharshtra. Envenoming is endemic in these areas, and others like them. The World Health Organization identified envenoming as one of the most neglected tropical diseases of the 21st century (Nature India, 2013). Additionally, both nonvenomous and …

Energy-Saving Hypothermia Reduces Flight Ability In Mourning Doves, Jennie M. Carr, Steven L. Lima May 2012

Energy-Saving Hypothermia Reduces Flight Ability In Mourning Doves, Jennie M. Carr, Steven L. Lima

Symposium 2012

Overwintering birds are frequently exposed to thermal challenges that can quickly decrease energy reserves, thus leading to an increase in the risk of starvation. During these periods of energetic hardship, many avian species use nocturnal hypothermia to conserve energy that would otherwise be lost remaining warm throughout the night (McKechnie & Lovegrove 2002). However, a cool body temperature (Tb) may limit a bird’s ability to monitor the environment and may slow their response to a potential threat. Thus, birds likely trade-off between the benefits of energy-saving hypothermia and the potential costs of reduced behavioral responsiveness to predators (Welton et al. …

Global And Specific Controls Of Protein Synthesis In Hibernators, Peipei Pan Dec 2011

Global And Specific Controls Of Protein Synthesis In Hibernators, Peipei Pan

UNLV Theses, Dissertations, Professional Papers, and Capstones

Mammalian hibernation is a highly dynamic physiological process that is composed of a series of torpor bouts, wherein hibernators oscillate between periods of torpor and interbout arousal. Although normally vital to homeostasis, many energetically consumptive processes such as translation or protein synthesis are virtually ceased during hibernation. Earlier studies indicated that protein synthesis had fallen to almost negligible levels. Cap-dependent initiation of translation is well regulated by eukaryotic translation initiation factor 4E (eIF4E) and its binding partner eIF4E-binding protein 1 (4E-BP1) when hibernators cycle in and out the torpor state. Herein, I investigated well-characterized regulatory mechanisms of global and specific …

Is Orthoptera Abundance And Distribution Across A Small Grassland Area Affected By Plant Biomass, Plant Species Richness, And Plant Quality?, Caitlin Falcone Dec 2010

Is Orthoptera Abundance And Distribution Across A Small Grassland Area Affected By Plant Biomass, Plant Species Richness, And Plant Quality?, Caitlin Falcone

Department of Environmental Studies: Undergraduate Student Theses

The choice of a specific microhabitat represents a compromise among a number of different factors organisms use to monitor habitat suitability. Grassland vegetation structure can vary widely along environmental gradients over a relatively small area. This vegetation structure can have a large influence on habitat selection by grasshoppers (Orthoptera). However, it is not clear which vegetation characteristics are most important in determining grasshopper abundance. We found that plant biomass, plant species richness, and plant quality all have an effect on grasshopper abundance and distribution. We observe that these affects vary both within and among the two years of data collection. …

Amphibians And Reptiles In A Mixed-Grass Prairie In Northwestern North Dakota, Robert K. Murphy, Robert F. Danley, Patricia K. Moore Dec 2006

Amphibians And Reptiles In A Mixed-Grass Prairie In Northwestern North Dakota, Robert K. Murphy, Robert F. Danley, Patricia K. Moore

The Prairie Naturalist

There have been almost no surveys of herpetofauna at 109 km2 Lostwood National Wildlife Refuge (LNWR) or surrounding counties in northwestern North Dakota, an area possibly undergoing significant environmental change from fossil fuel extraction and use. We used 30 m drift fences to survey amphibian and reptile species in prairie-wetland transition zones at LNWR during mid-May to early-July in 1985 to 1987, and again in 1999 and 2000. We captured only four amphibian and two reptilian species and noted one other reptilian species incidental to our survey. Several species expected to occur in the area were not detected.
