A New Species Of Vaejovis From The Patagonia Mountains, Southern Arizona (Scorpiones: Vaejovidae), Richard F. Ayrey 2018 Marshall University

A New Species Of Vaejovis From The Patagonia Mountains, Southern Arizona (Scorpiones: Vaejovidae), Richard F. Ayrey

Euscorpius

A new scorpion species, Vaejovis patagonia sp. nov. is described and placed in the “vorhiesi” group. This small, dark brown species is found near Patagonia, Arizona. It is geographically closest to V. troupi Ayrey & Soleglad, V. grahami Ayrey & Soleglad and V. vorhiesi Stahnke. Those three species are found in a triangle surrounding the Patagonia Mountains, the locality of Vaejovis patagonia. The pedipalp fixed finger has 5 ID denticles and the movable finger has 6, like most, but not all, of the other southern Arizona Vaejovis. Carapace of female is shorter than metasomal segment V.

Revised diagnoses are provided for the genus Butheolus, and for the species B. thalassinus Simon, 1882, and B. villosus Hendrixson, 2006, a ...


A Quantitative Analysis Of The Effects Of Urbanization, Mesophication And Prescribed Burns On Oak Woodlands In The Chicago Metropolitan Area, Chad Populorum 2018 Augustana College, Rock Island Illinois

A Quantitative Analysis Of The Effects Of Urbanization, Mesophication And Prescribed Burns On Oak Woodlands In The Chicago Metropolitan Area, Chad Populorum

Celebration of Learning

Urban expansion has had devastating impacts on forest ecosystems, especially within the past century. Human attempts to dominate nature have diminished natural disturbance regimes, which have maintained the biodiversity and historic composition of these ecosystems. Fires have been a prominent force in maintaining the structure of oak, hickory and other heliophytic (sun loving and fire-adapted) forest systems. Human induced fire suppression has led to mesophication across North America. Mesophication is the transition from drier conditions with open canopies to wetter conditions with closed canopies. These new conditions decrease the survival rates of these important species and begin to favor mesophytic ...


Radical Social Ecology As Deep Pragmatism: A Call To The Abolition Of Systemic Dissonance And The Minimization Of Entropic Chaos, Arielle Brender 2018 Fordham University

Radical Social Ecology As Deep Pragmatism: A Call To The Abolition Of Systemic Dissonance And The Minimization Of Entropic Chaos, Arielle Brender

Student Theses 2015-Present

This paper aims to shed light on the dissonance caused by the superimposition of Dominant Human Systems on Natural Systems. I highlight the synthetic nature of Dominant Human Systems as egoic and linguistic phenomenon manufactured by a mere portion of the human population, which renders them inherently oppressive unto peoples and landscapes whose wisdom were barred from the design process. In pursuing a radical pragmatic approach to mending the simultaneous oppression and destruction of the human being and the earth, I highlight the necessity of minimizing entropic chaos caused by excess energy expenditure, an essential feature of systems that aim ...


Secrets Of A Rare Bird: Breeding Behavior Of The Gray-Breasted Flycatcher (Lathrotriccus Griseipectus) In Ecuador, William Harris Kirkpatrick 2018 University of Tennessee, Knoxville

Secrets Of A Rare Bird: Breeding Behavior Of The Gray-Breasted Flycatcher (Lathrotriccus Griseipectus) In Ecuador, William Harris Kirkpatrick

EURēCA: Exhibition of Undergraduate Research and Creative Achievement

The Tumbesian region of southwestern Ecuador and northwestern Peru is home to a large number of endemic bird species. Many of these species are threatened with extinction, and little is known about their basic biology. Thus, information regarding natural history of species in the region is needed to guide conservation management. We studied the reproductive biology of the Gray-breasted Flycatcher, Lathrotriccus griseipectus, a small Tyrannid that lives in the Tumbesian region. Due to habitat destruction, the range size of L. griseipectus has dwindled and the species is now listed as Vulnerable on the IUCN Red List. We used a mounted ...


Reproductive Effort And Lipid Dynamics Of The Emerald Shiner (Notropis Atherinoides) In The Upper Niagara River, New York, Christopher A. Osborne 2018 State University of New York College at Buffalo - Buffalo State College

Reproductive Effort And Lipid Dynamics Of The Emerald Shiner (Notropis Atherinoides) In The Upper Niagara River, New York, Christopher A. Osborne

Biology Theses

Life history theory predicts that reproductive characteristics of organisms will be shaped by biotic and abiotic factors to maximize their overall fitness. In this study, I investigated how growth, reproductive effort, and lipid dynamics vary ontogenetically and seasonally for emerald shiners (Notropis atherinoides) in the upper Niagara River. Growth rates were highest in age 2 shiners and lower in age 1 and age 3 individuals. Evidence of reproduction was found beginning at age 1, and reproductive investment as measured by ovarian lipid content was lowest in age 1 and age 2 individuals and greatest in age 3 fish. All age ...

Gulls, Martin S. Lowney, Scott F. Beckerman, Scott C. Barras, Thomas W. Seamans 2018 USDA, Wildlife Services

Gulls, Martin S. Lowney, Scott F. Beckerman, Scott C. Barras, Thomas W. Seamans

Wildlife Damage Management Technical Series

Abundant gull (Figure 1) populations in North America have led to a variety of conflicts with people. Gulls cause damage at aquaculture facilities and other properties, and often collide with aircraft. Their use of structures on and near water results in excessive amounts of bird droppings on boats and docks. Their presence near outdoor dining establishments, swimming beaches, and recreational sites can lead to negative interactions with people. Large amounts of gull fecal material pollutes water and beaches resulting in drinking water contamination and swim bans. A combination of dispersal techniques, exclusion and limited lethal control may reduce damage to ...

Modeling Culex Tarsalis Habitat Suitability In The Great Plains Of Montana, Teal Bullick 2018 Carroll College

Modeling Culex Tarsalis Habitat Suitability In The Great Plains Of Montana, Teal Bullick

Carroll College Student Undergraduate Research Festival

As the leading cause of arbovirus encephalitis in the United States, West Nile Virus (WNV) poses a public health risk in the state of Montana where infection rates in mosquitoes can be as high as 15%. Spatial modeling can serve as a tool for predicting outbreaks and directing prevention measures. Models for the entire state of Montana currently exist that predict WNV risk and habitat suitability of the predominant vector species Culex tarsalis. After collecting additional mosquito vector samples in the summer of 2017, I used niche modeling techniques with historic and new presence-only data to build a Cx. tarsalis ...


Land Cover Association Of Culex Tarsalis In Western Montana, Harold McNally 2018 Carroll College

Land Cover Association Of Culex Tarsalis In Western Montana, Harold Mcnally

Carroll College Student Undergraduate Research Festival

Cx. tarsalis is the major vector of West Nile Virus (WNV) in Montana, so a higher concentration of Cx. tarsalis would most likely correspond to an area of high WNV incidence. Previous studies performed in the U.S. found that wetland land cover had a positive influence on Cx. tarsalis, while the studies on Normalized Difference Vegetation Index (NDVI) presented conflicting results. In this experiment I attempted to answer the question: Does land cover type and NDVI affect Culex tarsalis distribution in Western Montana? It was hypothesized that both land cover type and a high NDVI value would have a ...

Interactions And Pathogen Transmission Between Carnivores In Madagascar, Fidisoa Rasambainarivo 2018 University of Missouri, St. Louis

Interactions And Pathogen Transmission Between Carnivores In Madagascar, Fidisoa Rasambainarivo

Dissertations

Introduced carnivores exert considerable pressure on native predators through predation, competition and disease transmission. Improved understanding of determinant factors of interactions and pathogen transmission between introduced and endemic wildlife may help to predict disease emergence, avoid pathogen spillover and help control outbreaks. Using non-invasive camera traps, I identified areas where transmission of pathogens might happen through records of shared space-use within a protected area in Eastern Madagascar. I showed that indirect interactions between animals were more likely to occur near the research station which may constitute a disease transmission hotspot for carnivores in the landscape. Secondly, I investigated the associations ...


Can Omnivores Mediate The Effects Of Degradation?, Hannah Moore 2018 Murray State University

Can Omnivores Mediate The Effects Of Degradation?, Hannah Moore

Scholars Week

Omnivores feed at multiple trophic levels and have large effects on community structuring and stability. The magnitude and direction of such effects, whether omnivores stabilize or destabilize communities, remains unresolved. Shifts in omnivore diet and trophic position may be of particular importance to community stability in degraded habitats, where resources are sparse. For example, omnivores may reduce the severity and duration of community responses to degradationby dampening the effects of any disturbance-mediated trophic cascade. The relatively simple food webs of freshwater systems are ideal for studying trophic ecology, and in the western U.S., streams are heavily degraded by overgrazing ...

Wildlife In A Premier African Protected Area Do Not Perceive Ecotourists As Predators, Badru Mugerwa 2018 The University of Western Ontario

Wildlife In A Premier African Protected Area Do Not Perceive Ecotourists As Predators, Badru Mugerwa

Electronic Thesis and Dissertation Repository

Researchers have reported that the presence of ecotourists may displace or disturb wildlife with potentially adverse effects, and may be a more serious problem if wildlife perceive ecotourists as predators. I used a playback experiment to test if wildlife at Bwindi Impenetrable National Park, Uganda, perceive ecotourists as predators. I contrasted wildlife behavioural responses to vocalizations that simulate those of ecotourists to those of local predators (positive controls; dogs and the extirpated native apex predator, leopard) and a non-predator (negative control; insects). Using responses from 14 mammal species, I show that wildlife do not perceive ecotourists as predators, responding no ...
