Signature: ………………………………………………. Abstract The Appalachian Trail is the world’s longest hiking-only trail, covering roughly 2,200 miles of forest, mountains, ridges and plains. Each year a few thousand people set out to hike the entire length of the trail, estimated to take between five and seven months to complete. Numerous species of autonomous animals – wildlife – dwell on and around the trail, and it is the encounters that happen between these human and nonhuman animals that are the focus of this thesis. The research presented here is based wholly around narratives posted online as blogs by 166 Appalachian Trail hikers during the years 2015 and 2016. These narratives provide an insight into how hikers related to the self-directed animals that they temporarily shared a home with. Several recurring themes emerged to form the basis of the thesis chapters: many hikers viewed their trek as akin to a pilgrimage, which informed their perception of the animals that they encountered; American Black Bears (Ursus americanus), viewed as emblematic of the trail wilderness, made dwelling on the trail satisfyingly risky; hikers experienced strong feelings about some animals as being cute, and about others as being disgusting; along a densely wooded trail, experience of animals was often primarily auditory; the longer that they spent on the trail, the more hikers themselves experienced a sense of becoming wild. Through an analysis of these themes, it became clear that hikers thought about trail animals as meaning, or representing, something, in the context of their own narrative journey. Yet at the same time, the autonomous animals on the trail were experienced in complex, multifaceted, and sometimes even contradictory ways that succeeded in making them interesting to hikers in ways that they may never have anticipated. 2 TABLE OF CONTENTS INTRODUCTION pp. 7 My introduction to the Appalachian Trail pp. 13 The trail pp. 15 Why hike the AT? pp. 17 A wild life and wildlife on the trail pp. 20 Studies centred around the AT pp. 22 The Trek blogosphere pp. 23 Method pp. 26 Telling stories: Doing narrative research pp. 29 Am I cheating?

Blog post arcs: examples pp. 307 REFERENCES pp. 316 6 Introduction For people who live in contemporary Western societies, engagement with autonomous nonhuman animals can be limited or close to non-existent (see Berger, 1980; Bulbeck, 2005; Bulliet, 2005; Malamud, 1998; Turner 1996). Consequently, ideas about “wild” animals are formed primarily from cultural sources (which, from bedtime stories to nature documentaries, can only ever offer a pale representation of the “real” animal) or from zoos or organised “wildlife encounters” during which human and animal interactions are heavily managed (see Anderson, 1998; Berger, 1980; Bulbeck, 2005; Curtin, 2005; Franklin, 1999; Keul, 2013; Malamud, 1998; McNamara and Prideaux, 2011; Rothfels, 2002; Schänzel and Mcintosh, 2000). For most of us, our experience of autonomous animals is shaped almost entirely by cultural artefacts: plush toys, Disney films, wildlife documentaries, animal tattoos, 30-second comedy clips posted on social media platforms, charity appeals, taxidermy museum exhibits and breakfast cereal packaging. The notion that our media culture controls and shapes perceptions of wild animals has been extensively argued (see Baker, 2001; Berger, 1980; Bulliet, 2005; Franklin, 1999). Ingold questions whether unmediated perception of the animal is even possible for us. Do animals exist for us as meaningful entities only insofar as each may be thought to manifest or exemplify an ideal type constituted within the set of symbolic values making up the “folk taxonomy” specific to our culture? Or do we perceive animals directly, by virtue of their immersion in an environment that is largely ours as well, regardless of the images that we may hold of them, or of whether we hold such images at all? (1994: 12) For many people, there is such little opportunity to perceive (wild) animals directly, that the folk taxonomy that Ingold refers to is really all they have to go on when 7 thinking about certain animals, and the question, with regard to autonomous animals at least, goes unanswered. Over recent years there has been an increasing sense of impoverishment associated with our lack of contact with self-willed animals (see Bulbeck, 2005; Turner, 1996). This has been accompanied by a rise in modes of tourism focused on the immersion of the tourist in “natural” settings (nature tourism), the experience of nature with a conservation element (ecotourism) and tourist encounters with wild animals (wildlife tourism). These modes of tourism often overlap each other, but all are ultimately concerned with giving the tourist an encounter with “authentic wildness” (see Bulbeck, 2005; Cater, 2006; Curtin, 2005; Dearden, 1990; Fullagar, 2000; Hill et al., 2014; Keul, 2013; Kubo and Shoji, 2016; McNamara and Prideaux, 2011; Orams, 2000 and 2002; Reynolds and Braithwaite, 2001; Schänzel and Mcintosh, 2000; West and Carrier, 2004). The engagement with wild animals that this type of tourism offers is often tightly managed, featuring boundaries, fences, boardwalks, site maps, viewing times, feeding times, guides, rangers, crowds of other visitors, educational lectures, as well as strict regulations about what the tourist can do with her body, frequently including rules such as no stopping, no lingering, no approaching the animals, no reaching out towards the animals, no touching, no feeding, no prolonged eye contact.

  • About Pigs [PDF]
    May 2015 About Pigs Pigs are highly intelligent, social animals, displaying elaborate maternal, communicative, and affiliative behavior. Wild and feral pigs inhabit wide tracts of the southern and mid-western United States, where they thrive in a variety of habitats. They form matriarchal social groups, sleep in communal nests, and maintain close family bonds into adulthood. Science has helped shed light on the depths of the remarkable cognitive abilities of pigs, and fosters a greater appreciation for these often maligned and misunderstood animals. Background Pigs—also called swine or hogs—belong to the Suidae family1 and along with cattle, sheep, goats, camels, deer, giraffes, and hippopotamuses, are part of the order Artiodactyla, or even-toed ungulates.2 Domesticated pigs are descendants of the wild boar (Sus scrofa),3,4 which originally ranged through North Africa, Asia and Europe.5 Pigs were first domesticated approximately 9,000 years ago.6 The wild boar became extinct in Britain in the 17th century as a result of hunting and habitat destruction, but they have since been reintroduced.7,8 Feral pigs (domesticated animals who have returned to a wild state) are now found worldwide in temperate and tropical regions such as Australia, New Zealand, and Indonesia and on island nations, 9 such as Hawaii.10 True wild pigs are not native to the New World.11 When Christopher Columbus landed in Cuba in 1493, he brought the first domestic pigs—pigs who subsequently spread throughout the Spanish West Indies (Caribbean).12 In 1539, Spanish explorers brought pigs to the mainland when they settled in Florida.

  • Place Attachment, Place Identity and the Development of the Child's Self-Identity
    Place Attachment, Place Identity and the Development of the Child’s Self-identity: Searching the literature to develop an hypothesis Researching Primary Geography (2004) Chapter 6 in Researching Primary Geography edited by Simon Catling & Fran Martin 2004 ISBN 0-9538154-3-9 Place Attachment, Place Identity and the Development of the Child’s Self-identity: Searching the literature to develop an hypothesis Christopher Spencer Introduction In this chapter, I would like to use a specific argument about place and identity (encapsulated in the title) to offer a generalizable example of how to use published literature to develop and formulate one’s research hypothesis. When starting off, one may either feel that one’s new idea will have no predecessors, and thus ignore ‘standing on the shoulders’ of other thinkers; or alternatively, one may be awed by the amount of research which exists, and wrongly presume that there will not be room for one’s own contribution. For practically any area that you might think of, if you search the literature, you will probably find already existing research which is relevant; but it is also likely that you will not find exactly the thoughts that you are pursuing, or the application that interests you. So there is, indeed, a need for your research to take its place alongside the existing work, and to fill in one further part of the wall of knowledge. How to start? Do not assume that you can search the library or use a web search engine with just your terms of reference in mind. Think what synonyms and associated terms might lead you to fellow researchers’ work; free associate around the initial idea.

  • Place Attachment, Feeling of Belonging and Collective Identity in Socio-Ecological Systems: Study Case of Pegalajar (Andalusia-Spain)
    sustainability Article Place Attachment, Feeling of Belonging and Collective Identity in Socio-Ecological Systems: Study Case of Pegalajar (Andalusia-Spain) Javier Escalera-Reyes Department of Social Anthropology, Psychology and Public Health, Universidad Pablo de Olavide, 41013 Sevilla, Spain; [email protected] Received: 10 March 2020; Accepted: 18 April 2020; Published: 21 April 2020 Abstract: Shared feelings of belonging and attachment held by people in relation to the place they live, and the development of collective identities that such feelings can promote, should be taken into account when seeking to understand the configuration and operation of socio-ecological systems (SES), in general, and the impact these factors have on SES adaptability, transformability and resilience, in particular. However, these topics have not been examined in enough depth in prior research. To address the effects of people’s feelings of place attachment and belonging in specific SES and the impacts they have on the aforementioned properties, in addition to theoretical instruments appropriate to the emotional and cognitive nature of this kind of phenomena, in-depth empirical qualitative studies are required to enhance understanding of the cultural and symbolic dimensions of the SES of which they are part. In this regard, the analysis of people–place connections, feelings of belonging and territorial identifications (territoriality) is strategic to understanding how the biophysical and the socio-cultural are interconnected and structured within SES. This article is based on a case study implemented through long-standing ethnographic research conducted in Pegalajar (Andalusia-Spain), which examined the struggle of the local population to recover the water system on which the landscape, as well as the ways of life that sustain their identity as a town, has been built.

Humans construct humanity and personhood partially via interactions with other-than-human persons, such as animals, plants, and objects. I examine ritualized interactions between humans and others-than-human in a southeastern Indigenous "natureculture," exploring the intersections of ontology, personhood, and performance practice. Pvlvcekolv, an animistic Florida-based tribal town with a ceremonial Fire that pre-dates European Contact, maintains a centuries-old ritual tradition, the busk. Sometimes known as "Green Corn Ceremonialism," many Native communities share this tradition, including ii Cherokee, Chickasaw, Seminole, Yuchi, and other Creek peoples historically and in the present day. Performing the songs, dances, and ritual actions of the busk places participants into dialogue with other-than-human persons.

  • And the Naked Mole-Rat (Heterocephalus Glaber)
    ASPECTS OF OLFACTORY COMMUNICATION IN THE DWARF HAMSTER (PHODOPUS SUNGORUS) AND THE NAKED MOLE-RAT (HETEROCEPHALUS GLABER) A Dissertation Presented to the Faculty of the Graduate School of Cornell University In Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy by Frank Robert Castelli December 2017 © 2017 Frank Robert Castelli ASPECTS OF OLFACTORY COMMUNICATION IN THE DWARF HAMSTER (PHODOPUS SUNGORUS) AND THE NAKED MOLE-RAT (HETEROCEPHALUS GLABER) Frank Robert Castelli, Ph. D. Cornell University 2017 Olfactory communication is an understudied phenomenon, likely due to human bias against this modality of communication. I expanded our knowledge of olfactory communication by testing the following hypotheses: self-grooming is a form of olfactory communication in the dwarf hamster Phodopus sungorus; naked mole-rats (Heterocephalus glaber) are capable of social-dominance-based discrimination of odor; and rolling behaviors of naked mole-rats function as a form of scent-marking. Self-grooming is ubiquitous among mammals, yet our knowledge of the functions of this behavior beyond cleaning the body surface is limited. Dwarf hamsters were exposed to cotton nesting material scented by same-sex and opposite-sex conspecifics, as well as an unscented control. As predicted, subjects self-groomed more in response to conspecific odor than unscented controls, an important first step in demonstrating communication. Furthermore, self-grooming in response to opposite- sex odor was higher than same-sex odor and unscented controls, which did not differ from each other, suggesting that its communicative function is to attract a mate. Naked mole-rats live in underground eusocial colonies in which social dominance plays important roles in their reproductive division of labor, cooperation, mate choice, and access to food.

    MCPB Item No. Date: 11/30/17 November 23, 2017 MEMORANDUM TO: Montgomery County Planning Board VIA: Michael F. Riley, Director Mitra Pedoeem, Deputy Director Michael Ma, Chief, Park Development Division (PDD) Patricia McManus, Design Sec on Supervisor, (PDD) FROM: Aaron Feldman, Landscape Architect (PDD), 301-650-2887 SUBJECT: Amendment to the Facility Plan for the North Branch Hiker Biker Trail STAFF RECOMMENDATION Approve modifi ca ons to the 2013 Facility Plan for the North Branch Hiker-Biker Trail, specifi cally: 1) Relocate the proposed trailhead and parking lot from Muncaster Mill Road to Meadowside Lane. 2) Relocate the proposed bridge from near the Meadowside Nature Center to just south of the Intercounty Connector (ICC). PROJECT SUMMARY In March of 2017, during the detailed design phase of the project, the Norbeck Manor Homeowners Associa on contacted staff with concerns about the proposed loca on of a trailhead and parking lot intended to serve the North Branch Trail. Staff a ended a Homeowners Associa on mee ng, reviewed the concerns, studied alterna ves and presented them at a subsequent public mee ng for feedback. In light of strong community support for reloca ng the trailhead and parking lot from the loca on shown in the approved 2013 Facility Plan, staff is returning to the Planning Board for approval of the new loca on and other minor modifi ca ons to the overall plan. ExisƟ ng CondiƟ ons Located within both Rock Creek Regional Park and the North Branch Stream Valley Park, the North Branch Hiker-Biker Trail is a 2.2 mile-long segment of a con nuous regional trail system that will eventually extend from the District of Columbia northward to Olney.
