The Economic Impacts Of Blackbird (Icteridae) Damage To Sunflower In The Usa, Karina Ernst, Julie Elser, George Linz, Hans Kandel, Jason Holderieath, Samantha Degroot, Steven Shwiff, Stephanie Shwiff

Jason Holderieath

BACKGROUND: Blackbird (Icteridae) damage to ripening sunflower (Helianthus annuus L.) has been a persistent economic issue in the USA for the last five decades. To quantify losses, we surveyed blackbird damage from 2001 to 2013 (excluding 2004) to physiologically mature sunflower in eight states: North Dakota, South Dakota, Texas, Nebraska, Minnesota, Colorado, Kansas, and Vermont.

RESULTS:We pooled data gathered during the most recent 5 years (2009 to 2013) of the survey and found losses averaged $US2.5 million and $US11.3 million for confectionery and oilseed hybrids, respectively. Three states, North Dakota, South Dakota, and Nebraska, had sufficient acreage and bird damage …

Outdoor Cats: An Animal Welfare And Protection Perspective, John Hadidian, Inga Gibson, Susan Hagood, Nancy Peterson, Bernard Unti, Betsy Mcfarland, Katie Lisnik, Heather Bialy, Inga Fricke, Kathleen Schatzmann, Jennifer Fearing, Pam Runquist, Andrew N. Rowan (Ed.)

Andrew N. Rowan, DPhil

First raised as a serious conservation issue more than 100 years ago, the impact of free-roaming cats on wildlife has been a subject of debate, controversy, and conflict since then. Cats have been tied directly to the extinction of sensitive species in island environments and implicated as major threats to certain wildlife populations elsewhere. Yet the study of free-roaming cats and the problems attributed to them lags behind the standards of research typical with more traditional vertebrate “pest” species. Alternative management approaches, ranging from traditional practices such as removal and depopulation to emerging concepts such as Trap- Neuter-Return (TNR), have …

Dc Birdscape: A Program For Monitoring Neotropical Migratory Birds In Washington, Dc, John Sauer, John Hadidian, Sam Droege, Paul Handly, Carolyn Williams, Christopher Swarth, George Didden, Jane Huff

John Hadidian, PhD

Urban and suburban habitats often contain a variety of Neotropical migratory birds, but are poorly sampled by programs such as the North American Breeding Bird Survey. DC Birdscape was developed to inventory and monitor birds in Washington, DC. Birds were surveyed using a systematic sample of point counts during 1993-1995. Results indicate that species richness of Neotropical migratory birds varied among land-use categories, and that maximum species richness occurred in parkland habitats. Although DC Birdscape has provided relevant information on bird distribution and species richness, it is unclear whether the information is of sufficient management interest to support its continuation …

What Is A Humane Wildlife Control Service?, John Griffin, Lori Thiele, Pamela Lough, Janet Snyder, Maggie Brasted, John Hadidian

John Hadidian, PhD

In May 2007, The Humane Society of the United States launched a for-fee business called Humane Wildlife Servicessm to engage in wildlife control jobs in the Washington, D.C. metro area. We had several purposes in launching this service. First, we felt it necessary to offer a service to customers in our home base area that allowed them to choose a wildlife removal company that did not trap and relocate, or trap and kill, animals. Second, we wished to directly experience and test the operational and conceptual challenges associated with this sort of service. Third, we wished to develop a model …

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

John Hadidian, PhD

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 …

The “Nuisance” Wildlife Control Industry: Animal Welfare Concerns, John Hadidian, Laura J. Simon, Michele R. Childs

John Hadidian, PhD

The recent and rapid growth of the private “nuisance” wildlife control industry follows the unparalleled current period of urban and suburban expansion. Nuisance wildlife control businesses range from simple home-based services to sophisticated franchised businesses. The nuisance wildlife control operator may hold an advanced degree in the wildlife sciences, or simply be an entrepreneur without formal education or even background experience in wildlife. State and federal agencies may participate directly or indirectly in nuisance wildlife control, in activities ranging from dissemination of advice or information to actual participation in programs that may lead to removal of animals. Naturally, all of …

Protecting Biodiversity In British Columbia: Recommendations For Developing Species At Risk Legislation, Alana R. Westwood, Sarah P. Otto, Arne Mooers, Chris Darimont, Karen E. Hodges, Chris Johnson, Brian M. Starzomski, Cole Burton, Kai M. A. Chan, Marco Festa-Bianchet, Shaun Fluker, Sumeet Gulati, Aerin L. Jacob, Dan Kraus, Tara G. Martin, Wendy J. Palen, John D. Reynolds, Jeannette Whitton

Chris Darimont, PhD

British Columbia has the greatest biological diversity of any province or territory in Canada. Yet increasing numbers of species in British Columbia are threatened with extinction. The current patchwork of provincial laws and regulations has not effectively prevented species declines. Recently, the Provincial Government has committed to enacting an endangered species law. Drawing upon our scientific and legal expertise, we offer recommendations for key features of endangered species legislation that build upon strengths and avoid weaknesses observed elsewhere. We recommend striking an independent Oversight Committee to provide recommendations about listing species, organize Recovery Teams, and monitor the efficacy of actions …

A Moral Panic Over Cats, William S. Lynn, Francisco J. Santiago-Ávila, Joann Lindenmayer, John Hadidian, Arian D. Wallach, Barbara J. King

John Hadidian, PhD

Some conservationists believe that free-ranging cats pose an enormous risk to biodiversity and public health and therefore should be eliminated from the landscape by any means necessary. They further claim that those who question the science or ethics behind their arguments are science deniers (merchants of doubt) seeking to mislead the public. As much as we share a commitment to conservation of biodiversity and wild nature, we believe these ideas are wrong and fuel an unwarranted moral panic over cats. Those who question the ecological or epidemiological status of cats are not science deniers, and it is a false analogy …

Just Preservation, A. Treves, F. J. Santiago-Ávila, W. S. Lynn

William S. Lynn, PhD

We are failing to protect the biosphere. Novel views of conservation, preservation, and sustainability are surfacing in the wake of consensus about our failures to prevent extinction or slow climate change. We argue that the interests and well-being of non-humans, youth, and future generations of both human and non-human beings (futurity) have too long been ignored in consensus-based, anthropocentric conservation. Consensus-based stakeholder-driven processes disadvantage those absent or without a voice and allow current adult humans and narrow, exploitative interests to dominate decisions about the use of nature over its preservation for futurity of all life. We propose that authentically non-anthropocentric …

Reproductive Success Of Eastern Bluebirds (Siala Sialis) On Suburban Golf Courses, Kerri L. Cornell, Caitlin R. Kight, Ryan B. Burdge, Alex R. Gunderson, Joanna K. Hubbard, Allyson K. Jackson, Joshua E. Leclerc, Marie L. Pitts, John P. Swaddle, Daniel A. Cristol

Daniel Cristol

Understanding the role of green space in urban—suburban landscapes is becoming critical for bird conservation because of rampant habitat loss and conversion. Although not natural habitat, golf courses could play a role in bird conservation if they support breeding populations of some native species, yet scientists remain skeptical. In 2003–2009, we measured reproduction of Eastern Bluebirds (Siala sialis) in Virginia on golf courses and surrounding reference habitats, of the type that would have been present had golf courses not been developed on these sites (e.g., recreational parks, cemeteries, agriculture land, and college campus). We monitored >650 nest boxes …

The International Whaling Commission—Beyond Whaling, Andrew J. Wright, Mark P. Simmonds, Barbara Galletti Vernazzani

Mark P. Simmonds, OBE

Since its establishment in 1946 as the international body intended to manage whaling, the International Whaling Commission (IWC) has expanded its areas of interest to ensure the wider conservation of whales. Several key conservation topics have been taken forward under its auspices including climate change, chemical and noise pollution, marine debris and whale watching. Work on each of these topics at the IWC has grown substantially since the 1990s and remains ongoing. Important developments were the establishment of the Standing Working Group on Environmental Concerns in 1996 and the IWC’s Conservation Committee in 2003. Trying to address this diverse set …

Grizzly Bear Monitoring By The Heiltsuk People As A Crucible For First Nation Conservation Practice, William G. Housty, Anna Noson, Gerald W. Scoville, John Boulanger, Richard M. Jeo, Chris T. Darimont, Christopher E. Filardi

Chris Darimont, PhD

Guided by deeply held cultural values, First Nations in Canada are rapidly regaining legal authority to manage natural resources. We present a research collaboration among academics, tribal government, provincial and federal government, resource managers, conservation practitioners, and community leaders supporting First Nation resource authority and stewardship. First, we present results from a molecular genetics study of grizzly bears inhabiting an important conservation area within the territory of the Heiltsuk First Nation in coastal British Columbia. Noninvasive hair sampling occurred between 2006 and 2009 in the Koeye watershed, a stronghold for grizzly bears, salmon, and Heiltsuk people. Molecular demographic analyses revealed …

Population Genetic Structure Of Gray Wolves (Canis Lupus) In A Marine Archipelago Suggests Island-Mainland Differentiation Consistent With Dietary Niche, Astrid V. Stronen, Erin L. Navid, Michael S. Quinn, Paul C. Paquet, Heather M. Bryan, Chris T. Darimont

Chris Darimont, PhD

Background: Emerging evidence suggests that ecological heterogeneity across space can influence the genetic structure of populations, including that of long-distance dispersers such as large carnivores. On the central coast of British Columbia, Canada, wolf (Canis lupus L., 1758) dietary niche and parasite prevalence data indicate strong ecological divergence between marine-oriented wolves inhabiting islands and individuals on the coastal mainland that interact primarily with terrestrial prey. Local holders of traditional ecological knowledge, who distinguish between mainland and island wolf forms, also informed our hypothesis that genetic differentiation might occur between wolves from these adjacent environments.

Results: We used microsatellite genetic markers …

Intrapopulation Diversity In Isotopic Niche Over Landscapes: Spatial Patterns Inform Conservation Of Bear–Salmon Systems, Megan S. Adams, Christina N. Service, Andrew Bateman, Mathieu Bourbonnais, Kyle A. Artelle, Trisalyn Nelson, Paul C. Paquet, Taal Levi, Chris T. Darimont

Chris Darimont, PhD

Intrapopulation variability in resource acquisition (i.e., niche variation) influences population dynamics, with important implications for conservation planning. Spatial analyses of niche variation within and among populations can provide relevant information about ecological associations and their subsequent management. We used stable isotope analysis and kernel-weighted regression to examine spatial patterns in a keystone consumer–resource interaction: salmon (Oncorhynchus spp.) consumption by grizzly and black bears (Ursus arctos horribilis, n = 886; and Ursus americanus, n = 557) from 1995 to 2014 in British Columbia (BC), Canada. In a region on the central coast of BC (22,000 km² ), grizzly bears consumed …

Mismeasured Mortality: Correcting Estimates Of Wolf Poaching In The United States, Adrian Treves, Kyle A. Artelle, Chris T. Darimont, David R. Parsons

Chris Darimont, PhD

Measuring rates and causes of mortalities is important in animal ecology and management. Observing the fates of known individuals is a common method of estimating life history variables, including mortality patterns. It has long been assumed that data lost when known animals disappear were unbiased. We test and reject this assumption under conditions common to most, if not all, studies using marked animals. We illustrate the bias for 4 endangered wolf populations in the United States by reanalyzing data and assumptions about the known and unknown fates of marked wolves to calculate the degree to which risks of different causes …

Indigenous Knowledge And Science Unite To Reveal Spatial And Temporal Dimensions Of Distributional Shift In Wildlife Of Conservation Concern, Christina N. Service, Megan S. Adams, Kyle A. Artelle, Paul C. Paquet, Laura V. Grant, Chris T. Darimont

Chris Darimont, PhD

Range shifts among wildlife can occur rapidly and impose cascading ecological, economic, and cultural consequences. However, occurrence data used to define distributional limits derived from scientific approaches are often outdated for wide ranging and elusive species, especially in remote environments. Accordingly, our aim was to amalgamate indigenous and western scientific evidence of grizzly bear (Ursus arctos horribilis) records and detail a potential range shift on the central coast of British Columbia, Canada. In addition, we test the hypothesis that data from each method yield similar results, as well as illustrate the complementary nature of this coupled approach. Combining information from …

Explaining China’S Wildlife Crisis: Cultural Tradition Or Politics Of Development, Peter J. Li

Peter J. Li, PhD

This chapter is about China’s wildlife crisis. As the following sections attempt to demonstrate, abuse of and assault on wildlife in captivity and in the wild have reached an unprecedented level on the Chinese mainland in the reform era (1978–present). Shocking brutality against wildlife animals has been frequently exposed by Chinese and international media. To readers outside East Asia, they ask if the Chinese are culturally indifferent to animal suffering. Indeed, does the Chinese culture sanction cruelty to animals? Or is it the contemporary politics of economic development that is more directly responsible for the crisis?

Canis Lupus Cosmopolis: Wolves In A Cosmopolitan Worldview, William S. Lynn

William S. Lynn, PhD

The subject of wolf recovery in North America sparks heated controversy, both for and against. This paper explores how this subject is informed by cosmopolitan worldviews. These worldviews pull nature and culture into a common orbit of ethical meaning, with implications for the normative relationships that ought to pertain in landscapes shared by people and wolves. This theoretical outlook is illustrated using the controversy over wolves in the northeastern region of the United States. I conclude with a set of reflections on theorizing the cosmopolis, the interpretation of cosmopolitan landscapes, and living with cosmopolitan wolves.

The Ethics Of Wildlife Control In Humanized Landscapes, John Hadidian, Camilla H. Fox, William S. Lynn

William S. Lynn, PhD

The 21st century is witness to an unprecedented and rapid growth of human settlements, from urban centers to wilderness vacation resorts. Concurrent with this has been the growing tolerance and acceptance of many wild animals and humans for one another. This has created an expanding ‘zone’ of human-animal contacts, some number of which invariably result in conflicts. While the vast majority of our interactions with wild animals are undoubtedly benign, it is the conflict between wildlife and people that draws particularly close attention from the public. Animals viewed as vertebrate “pests” range from the small to the large, the timid …
