Este libro es destinado para el uso por biólogos del campo y otras personas, incluso biólogos de campo en el futuro que podrían estar en un curso de la universidad y trabajando en estudios y conservación de animales. Nuestro objetivo es que los biólogos usen este libro como (haciendo apología a nuestro colega Evan Cooch) una “introducción suave” al campo de la ecología cuantitativa. Esperamos convencer a los lectores que los métodos y aproximaciones del libro no son solo para los matemáticos, estadísticos y programadores de computadoras, sino que de hecho son herramientas esenciales para practicar la conservación en el …
When An Invasive Plant Fails To Invade, 2015 University of Nebraska - Lincoln
When An Invasive Plant Fails To Invade, Stephen L. Young
West Central Research and Extension Center, North Platte
In 2012, much of the US Midwest was gripped in one of the most severe droughts on record. While conducting experimental fieldwork at a site in Nebraska during June of that year, I noticed a single musk thistle (Carduus nutans; Figure 1) that appeared to be in the bolt or early flowering stage, which is typical for the species at that time. Here, however, two things were unusual: this plant was less than 1 meter tall (with adequate moisture and light, musk thistle typically grows to heights of 1–2.5 meters before flowering), and was only 3 months old (the bolt …

Rodríguez-Almaráz, Iris Banda-Villanueva, Lissette A. Sepúlveda-Hernández, Lilia Vela-Valladares, Andrea Cantú-Garza, Mauricio De La Maza-Benignos
Occasional Papers
We report rediscovery of the Chihuahuan Dwarf Crayfish Cambarellus chihuahuae at the desert spring Ojo Solo in Ejido Rancho Nuevo in Chihuahua, México. This species was reported to be extinct. Morphological evaluation of 12 voucher specimens confirmed the population as C. chihuahuae. Crayfish were abundant upon rediscovery in September 2012 and remained so throughout bimonthly monitoring from February 2014 to April 2015. Despite abundance at Ojo Solo, the species is critically imperiled, with four of its five native habitats dry and the remaining one in decline; however, a population was established at Ojo Caliente, a nearby natural refuge habitat we …

Is Your Learning Style Paranoid?, Kirby Farrell
kirby farrell
We learn—and grow—by engaging with anomalies: new things that don't fit our familiar categories. It's a gut process, not just a philosophical choice. Anxiety can make us paranoid about what's new and strange. Knowing that can spur fascination and help us to adapt.

Using Choice Experiment Valuation Methods To Measure Public Preference For A New National Park In Maine, 2015 Colby College
Using Choice Experiment Valuation Methods To Measure Public Preference For A New National Park In Maine, Alexander G. Wilsterman
Journal of Environmental and Resource Economics at Colby
With global population increasing faster than ever, the need to protect land from development is at an all-time high. This paper seeks the measure the public preference for a new national park located in northern Maine. A national park will both protect the land and inject a much-needed economic stimulus to the surrounding communities. The study uses the choice experiment valuation method to quantify its results. Through this revealed preference we can quantify which characteristics are most important to the public so that these characteristics may be considered if the project is ever approved.
Golf Courses In Maine: Land Type Valuation Versus A Hedonic Pricing Analysis, 2015 Colby College
Golf Courses In Maine: Land Type Valuation Versus A Hedonic Pricing Analysis, Gregory Ladd, Jason Buco
Journal of Environmental and Resource Economics at Colby
Many studies have been conducted analyzing the economic impact of golf courses on the local communities. These studies examine economic impacts of tournaments, endorsements, and vacation expenses of the major golf courses in the United States. However, there is little research conducted on the environmental impact of Golf courses, specifically in Maine. This paper performs a hedonic pricing analysis using housing prices in proximity to golf courses and compares it to the valuation of various land types in Maine. Housing prices were collected in the towns of Auburn, and North Yarmouth both near and distant from the local golf course. …
Cost Benefit Analysis Of Café Standards Compared To The Alternative Fuel/Carbon Tax, 2015 Colby College
Cost Benefit Analysis Of Café Standards Compared To The Alternative Fuel/Carbon Tax, Brian Levinson
Journal of Environmental and Resource Economics at Colby
The Cafe Standards were introduced in 1975 following the Oil Embargo. The goals of this program were simple. To reduce co2 emissions in vehicles by increasing a mandatory average mpg level for car manufacturers in the United States. Recently, in 2012, the Obama Administration set new Cafe Standard requirements for car manufacturers. By 2025, all new cars on the road in the United States must average 54.5 miles per gallon, which would double the current 27 mpg average in place right now. While the intentions of this policy are to reduce co2 emissions while at the same time increasing savings …
The Economics Of The Audubon Society's Sanctuary Program For Golf Courses, 2015 Colby College
The Economics Of The Audubon Society's Sanctuary Program For Golf Courses, Dan Hyszczak
Journal of Environmental and Resource Economics at Colby
Millions of people play golf every year, and in 2011 Golf Courses gained $22 billion dollars in revenue. This statistic combined with golf’s inherent place in the natural environment lead to questions of value and development for golf course owners. In 1991, The Audubon Society created their Cooperative Sanctuary Program for Golf Courses (ACSP) to promote environmentally sustainable practices for golf courses and to recognize the courses that are the most environmentally in both the United States and around the world.
This paper builds off of prior research that connects golf course beauty with revenue by examining the effects of …
Preferences For Coral Reef And Fishery Management In Okinawa, Japan, 2015 Colby College
Preferences For Coral Reef And Fishery Management In Okinawa, Japan, Nils Carlson
Journal of Environmental and Resource Economics at Colby
This study is an example of how a nonmarket valuation method – a choice experiment – can be used to influence and guide ecosystem conservation efforts. Using a choice experiment survey, this study estimates the willingness to pay (WTP) for certain hypothetical attributes of a restored and conserved coral reef in Okinawa, Japan. I find that an increase in the amount of fish available to catch in ten years as well as an increase in the extent and health of the coral reefs and the number of marine biodiversity found in the Okinawan waters after ten-years, both positively affect respondent’s …

A Survey On Climate Change: How Beliefs Shape Responsibility, 2015 Colby College
A Survey On Climate Change: How Beliefs Shape Responsibility, Connor P. Clancy, Sarah Beth Solomon
Journal of Environmental and Resource Economics at Colby
This paper examines the lack of awareness and feelings of personal responsibility for climate change. Previous literature suggests that while part of the United States population may be aware of climate change, they do not feel personally responsible for causing it despite feeling climate change’s effects just like everyone else. Furthermore, studies suggest that individuals also do not believe climate change will affect them now, but rather it is an issue for future generations. Using a survey, we examine which demographics and personal factors are most important in eliciting awareness for climate change, and furthermore, personal responsibility for its effects. …

Doctoral Dissertations
The objective of this study is to assess the potential of two amphibians species, Eastern Red-backed Salamander (Plethodon cinereus (Green)) and Eastern Red-spotted Newt (Notopthalmus viridescens viridescens Rafinesque), as indicator species of forest disturbances at Harvard Forest, located in Petersham, Massachusetts, United States. Specifically, I 1) assess the impacts of these focal species to decline of hemlock forests in Harvard Forest; 2) calibrate abundance indices of P. cinereus based on artificial and natural objects surveys with a population size estimator based on depletion sampling; and 3) assess the potential of these salamanders as indicator species by developing an …
Protecting Ecosystems, Culture, And Human Rights In Chile Through Indigenous And Community-Conserved Territories And Areas, 2015 SIT Graduate Institute
Protecting Ecosystems, Culture, And Human Rights In Chile Through Indigenous And Community-Conserved Territories And Areas, William G. Crowley
Capstone Collection
In environmental conservation circles around the world, the contributions of indigenous peoples and local communities to the sustainable maintenance of ecosystems and natural resources are being given increased attention. Whether for cultural, spiritual, economic, or other purposes, the use of traditional and local knowledge of habitat and resource management is slowly making its way into the modern environmental movement, and is being incorporated into the dominant conservation paradigms. These managed areas, known as Indigenous and Community-Conserved Territories and Areas, or ICCAs, are defined by the International Union for Conservation of Nature as “natural and/or modified ecosystems containing significant biodiversity …
The Enhancement Of Wild Bees (Hymenoptera: Apoidea) For Pollination Security, 2015 University of Maine
The Enhancement Of Wild Bees (Hymenoptera: Apoidea) For Pollination Security, Eric M. Venturini
Electronic Theses and Dissertations
The acreage of pollinator-dependent crops continues to expand across the globe. Simultaneously, honey bee hives – an annually rented commodity that growers rely on – are more expensive every year and in some cases, scarce. In response, pollinator-dependent growers seek alternative pollinators. One approach is installing bee pasture on farms, a strategy that enables systems-based farmers to become in-situ farm-scale habitat managers. This thesis first presents a review of the literature on bee pasture plantings and provides a brief overview of some methods for assessing their impacts on the pollinator community. There are three major gaps in current bee pasture …
Conservation Planning In A Changing World, 2015 University of Tennessee - Knoxville
Conservation Planning In A Changing World, Austin Walker Milt
Doctoral Dissertations
As a science and practice dedicated to preventing, stopping, and reversing negative effects on nature, conservation is constantly faced with new challenges. Combine this fact with the rise of large, freely available datasets and computational power, and the result is a need to advance the methods and conceptual approach to conservation planning. In my dissertation I present novel methods and address research questions that aim to keep conservation science and practice relevant and effective in a changing world. This picture of continual change is illustrated in Chapter 1, in which I explore how the ongoing collection of observations of rare …
Evolution And Phylogeny Of The Parasitoid Subfamily Phasiinae (Diptera: Tachinidae), 2015 University of Tennessee - Knoxville
Evolution And Phylogeny Of The Parasitoid Subfamily Phasiinae (Diptera: Tachinidae), Jeremy Daniel Blaschke
Doctoral Dissertations
The first molecular phylogenetic analysis of the agriculturally important parasitoid subfamily Phasiinae (Diptera: Tachinidae) is presented, estimated from 128 worldwide taxa (80 genera) and approximately 7.6 kilobases of nuclear data. Special emphasis is placed on taxa with controversial taxonomic placement. The resultant phylogenetic tree is used to reconstruct ancestral character states, trace the evolution of significant adaptive traits within the Tachinidae, and test hypotheses about the classification of Phasiinae. Subfamily placements of the taxa Eutherini, Epigrimyiini, Litophasia, Strongygastrini, and Parerigonini are confidently resolved, the former three within Dexiinae and the latter two within Phasiinae. Due to sparse molecular evidence, …
