Militarization Of Conservation, Daniel Ryan Michel 2018 The Graduate Center, City University of New York

Militarization Of Conservation, Daniel Ryan Michel

All Dissertations, Theses, and Capstone Projects

The world is facing biological diversity extinction of its wildlife solely caused by humans. One of the leading causes of the extinction crisis is attributed to poaching and the illegal trade of wildlife products. In search of finding suitable methods to curb the crisis, a dichotomy of overarching solutions has arisen: those who have advocated for community-based natural resource management and those who support militarized conservation. The focus of this paper is to delineate which method is, if any, the most appropriate when combatting poaching and the illegal wildlife trade. Concentrating on elephants (both African and Asian) and the rhinoceros ...


Utilizing Gis To Locate Endangered Gravel Hill Prairies Of The Wabash River Valley, Ryan W.R. Schroeder 2018 Purdue University

Utilizing Gis To Locate Endangered Gravel Hill Prairies Of The Wabash River Valley, Ryan W.R. Schroeder

Engagement & Service-Learning Summit: Partnerships for Purpose; March 1, 2017

The Gravel Hill Prairies (GHP’s) of the Wabash River Valley are an endangered ecosystem in the state of Indiana and provide optimal growing conditions for a number of state endangered plants. Currently only four remnants are known to exist near Lafayette, IN, found by a previous study conducted in 1980 by Post, Bacone, and Aldrich (Proceedings of the Indiana Academy of Science, 1984, vol. 94: 457-464). These unique ecosystems have been found to occur almost exclusively on soils classified as Rodman Gravelly Loams and Strawn-Rodman complexes which occur predominantly along the outwash terraces of the Wabash River and its ...


Muskrats, James E. Miller 2018 Mississippi State University

Muskrats, James E. Miller

Wildlife Damage Management Technical Series

The muskrat (Ondatra zibethicus) is a common, semi-aquatic rodent native to the United States (Figure 1). It spends its life in aquatic habitats and is well adapted for swimming.

Although muskrats are an important part of native ecosystems, their burrowing and foraging activities can damage agricultural crops, native marshes and water control systems, such as aquaculture and farm ponds and levees. Such damage can significantly impact agricultural crops like rice that rely on consistent water levels for growth.

Muskrats also cause damage by eating agricultural crops, other vegetation, and crayfish, mussels and other aquaculture products. Loss of vegetation from muskrat ...


Potential For Climate Induced Methane Hydrate Dissociation, Graham MacWilliams 2018 Pomona College

Potential For Climate Induced Methane Hydrate Dissociation, Graham Macwilliams

Pomona Senior Theses

Methane hydrates are frozen deposits of methane and water found in high pressure or low temperature sediments. When these deposits destabilize, large quantities of methane can be emitted into the atmosphere. This is significant to climate change because methane has 25 times more greenhouse gas potential than Carbon Dioxide. Worldwide, it is estimated there are between 2500 and 10000 gigatons of methane stored in hydrate deposits. This represents more carbon than all fossil fuels on Earth. It is estimated that between 200 and 2000 gigatons of methane are stored in hydrates in Arctic waters acutely vulnerable to greenhouse warming. Over ...


Brown Treesnakes: Methods And Approaches For Control, Larry Clark, Craig Clark, Shane R. Siers 2017 APHIS

Brown Treesnakes: Methods And Approaches For Control, Larry Clark, Craig Clark, Shane R. Siers

Larry Clark

This chapter summarizes the existing and emerging tools and strategies for the control of the invasive brown tree snake (Boiga irregularis, or BTS) on Guam and the prevention of its accidental transport to, and subsequent establishment on, other snake-free Pacic islands. The brown tree snake has long served as an example of the ecological economic damages that can be wrought by a single generalist vertebrate predator upon introduction to ecosystems that evolved in isolation and without native predators (Fritts and Rodda 1998; Wiles et al. 2003; Rodda and Savidge 2007). Our attempt to summarize the state of the art for ...


Use Of An Alternative Natural Weed Suppressant: Effects Of Parboiled Rice Hill Mulch On The Growth Of Container Weeds, Amy R. Fields-Taylor, Vanessa Slinger-Friedman 2017 Kennesaw State University

Use Of An Alternative Natural Weed Suppressant: Effects Of Parboiled Rice Hill Mulch On The Growth Of Container Weeds, Amy R. Fields-Taylor, Vanessa Slinger-Friedman

The Kennesaw Journal of Undergraduate Research

The Chattahoochee Nature Center (CNC) is one of the leading educational centers in Georgia about the ecology of the Chattahoochee River. Due to lack of man power, keeping down the weeds in the CNC plant nursery is one of those tasks that often gets left undone. The nursery becomes overgrown with invasive weed species. Understandably, they must sometimes resort to the use of herbicides, such as Roundup®, to keep the hundreds of native and endangered species of plants housed at CNC from being choked out by invasive weeds. This study tests the ability to suppress weed growth by use of ...


Large Birds Of Prey, Policies That Alter Food Availability And Air Traffic: A Risky Mix For Human Safety, Rubén Moreno-Opo, Antoni Margalida 2017 Ministry of Agriculture, Food and Environment. Spain

Large Birds Of Prey, Policies That Alter Food Availability And Air Traffic: A Risky Mix For Human Safety, Rubén Moreno-Opo, Antoni Margalida

Human–Wildlife Interactions

Raptors are considered to pose one of the greatest aviation bird strike risk. We investigated raptor bird strikes reported at the largest Spanish airport (Adolfo Suárez Madrid Barajas; AS-MB) from 2009 to 2016 to determine the factors contributing to the increased incidences and develop recommendations to mitigate the risks. We hypothesized that increased raptor bird strikes resulted from changes in foraging and dispersal patterns of Iberian Peninsula vultures (Aegypius spp. and Gyps spp.) after 2004-2005. We used information on raptor bird strikes obtained from official databases and published studies, reported incidences of raptor bird strikes and their characteristics (i.e ...


Illegal Wildlife Hunting And Trade In Southern Belize: An Assessment Of Impacts And Drivers, Blakely Rice 2017 SIT Graduate Institute

Illegal Wildlife Hunting And Trade In Southern Belize: An Assessment Of Impacts And Drivers, Blakely Rice

Capstone Collection

The use of wildlife as a resource is a common practice in all countries around the world, however, illegal activities are contributing to various environmental and social altercations amongst the involved communities and individuals, both directly and indirectly. This has led to the generalized global narrative on illegal wildlife hunting and trade as a “good vs. bad” convention. Although legal frameworks are in place to manage hunting and trade sustainably, governments and organizations often find themselves struggling to protect wildlife from illegal hunters, often facing dangerous situations thus the establishment of militarized conservation units. To date, most of the focus ...


Daphnia: A Possible Way To Combat A Deadly Amphibian Pathogen, Taylor Thomas 2017 University of San Diego

Daphnia: A Possible Way To Combat A Deadly Amphibian Pathogen, Taylor Thomas

Undergraduate Honors Theses

Globally there is a biodiversity crisis, with many groups of species threatened with extinction due to changes in the environment and human impacts. Amphibians are one such group and according to the IUCN, over 30% of amphibians are threatened by extinction. There are many factors have that can explain the decline of amphibians including pollution, habitat loss, climate change and disease. One factor is chytridiomycosis, an emerging infectious disease caused by the chytrid Batrachochytrium dendrobatidis. The chytrid enters the keratinized skin of the amphibian and asexually reproduces, where it disrupts host functions, often leading to host death.

Due to the ...

El Problema De La Lobesia Botrana. Un Caso Práctico Para Analizar El Dilema Entre La Urgencia Sanitaria Y El Derecho Humano A Un Medio Ambiente Sano - Informe Xumex 2017, Luis Gabriel Escobar Blanco

Luis Gabriel Escobar Blanco

El problema de la Lobesia Botrana, más allá de las consideraciones fitosanitarias y las consecuencias sobre la vitivinicultura cuyana, se constituye en un caso de estudio que permite analizar la actividad antrópica desde el principio y su impacto en el ambiente. Puede comenzarse desde la introducción de una especie invasora, sin predadores naturales, en un ecosistema culturalmente equilibrado que constituye una cadena productiva de alto valor agregado, hasta el análisis de las medidas tomadas para controlar su propagación e intentar erradicarla. The problem of Lobesia Botrana, beyond the phytosanitary considerations and the consequences in the viticulture of Cuyo, is a ...

A Place-Based Learning Community: Klamath Connection At Humboldt State University, Matt Johnson, Amy Sprowles, Katlin Overeem, Angela Rich

Learning Communities Research and Practice

A place-based learning community called Klamath Connection was designed to improve the academic performance of freshman in Science, Technology, Engineering, and Math (STEM) majors at Humboldt State University, a midsize public institution in a location geographically and culturally unfamiliar to the majority of its students. The program interweaves four high impact practices demonstrated to improve the success of students in STEM: a summer immersion, freshman year seminar, modified gateway courses, and peer mentoring. Each component is linked by an interdisciplinary theme unique to our geographic location and central to the communities that live within it, the Klamath River basin. This ...

A New Island Species Of Centruroides Marx, 1890 (Scorpiones: Buthidae) From The Southwestern Caribbean, Rolando Teruel, Brandon Myers 2017 Museo de Historia Natural “Tomás Romay”

A New Island Species Of Centruroides Marx, 1890 (Scorpiones: Buthidae) From The Southwestern Caribbean, Rolando Teruel, Brandon Myers

Euscorpius

Herein we describe a new species of the Buthidae scorpion genus Centruroides Marx, 1890. It occurs at least in two small offshore islands of the southwestern Caribbean: Cozumel in Mexico and Guanaja in Honduras, based upon type specimens from the former and photographic evidence from the latter. It belongs in the "gracilis" species-group and is most closely related to both Centruroides gracilis (Latreille, 1805) and Centruroides nigrescens (Pocock, 1898).

Electronic Theses and Dissertations

ESTIMATING WILDLIFE BIODIVERSITY OF PINE PLANTATION EDGES OF CONTRASTING ROTATIONAL STAGES: A CASE STUDY

By: Joshua Harris, Dr. Daniel Scognamillo, Dr. Gary Kronrad, and Dr. Jeremy Stovall

Abstract

Wildlife biodiversity was estimated amongst three loblolly pine (Pinus taeda) intra-plantation edge types of contrasting rotational phases in a two-year case study. Three structurally varied rotational phases that occur throughout plantation rotations combine to make three different edges: A= pre-thinned - post-thinned, B= pre-thinned - pre-clearcut, and C= post-thinned - pre-clearcut. For two summer seasons (May-August 2015-2016), invertebrates, birds, medium mammals, and small mammals were sampled in each edge type. Richness, extrapolated richness, two indices ...


Characterizing Mekk1: Candidate Behavioural Isolation Gene, Caryn Dooner 2017 The University of Western Ontario

Characterizing Mekk1: Candidate Behavioural Isolation Gene, Caryn Dooner

Electronic Thesis and Dissertation Repository

Behavioural isolation can occur due to divergence in aspects of courtship and mating, and can contribute to reproductive isolation. The purpose of this study is to determine how a gene, Mekk1, contributes to female rejection behaviour between D. melanogaster and D. simulans. Unique polymorphisms were identified within D. simulans Mekk1 that could contribute to behaviour, most of which are non-coding. Both transcripts of Mekk1 appear to be expressed at similar levels in D. simulans and D. melanogaster. These data also indicate that Mekk1 may be expressed in a specific region of the brain called the mushroom body, which has previously ...


Linking Taxonomic Diversity And Trophic Function: A Graph-Based Theoretical Approach, Marcella M. Jurotich, Kaitlyn Dougherty, Barbara Hayford, Sally Clark 2017 Wayne State College

Linking Taxonomic Diversity And Trophic Function: A Graph-Based Theoretical Approach, Marcella M. Jurotich, Kaitlyn Dougherty, Barbara Hayford, Sally Clark

Transactions of the Nebraska Academy of Sciences and Affiliated Societies

The purpose of this study is to develop a novel, visual method in analyzing complex functional trait data in freshwater ecology. We focus on macroinvertebrates in stream ecosystems under a gradient of habitat degradation and employ a combination of taxonomic and functional trait diversity analyses. Then we use graph theory to link changes in functional trait diversity to taxonomic richness and habitat degradation. We test the hypotheses that: 1) taxonomic diversity and trophic functional trait diversity both decrease with increased habitat degradation; 2) loss of taxa leads to a decrease in trophic function as visualized using a bipartite graph; and ...
