The scavenger spyglass: how recruiting hunters to watch carrion boosts wildlife research

Hunters support scavengers with seasonal pulses of carrion. If those hunters also deploy remote cameras at kill sites, they could simultaneously contribute data to wildlife research while gaining first-hand knowledge of scavenger ecology. In 2018–2020, we recruited hunters to monitor carcasses and offal with remote cameras across western Montana, USA. We increased our sampling effort by also setting up cameras following successful elk (Cervus canadensis) hunts at a private ranch. Cameras recorded 19 scavenger species. Golden eagles (Aquila chrysaetos) appeared at 55% of sites, and 3 individuals wore auxiliary markers, demonstrating how hunters can augment efforts to detect tagged wildlife. Cameras also documented elusive predators (e.g., wolves [Canis lupus]) and a seasonality of scavenging among American black bears (Ursus americanus). At 42% of the sites, ≥1 cervid investigated the carrion within 1 m, a behavior that may transmit the prions associated with chronic wasting disease. Hunters are willing and competent citizen scientists that can help generate wildlife observations at a broad spatial scale.     

Human genome research and the public interest: progress notes from an American science policy experiment.

This essay reviews the efforts of the U.S. Human Genome Project to anticipate and address the ethical, legal, and social implications of new advances in human genetics. Since 1990, approximately $10 million has been awarded by the National Institutes of Health and the Department of Energy, in support of 65 research, education, and public discussion projects. These projects address four major areas of need: (1) the need for both client-centered assessments of new genetic services and for improved knowledge of the psychosocial and ethnocultural factors that shape clients' clinical genetic experiences; (2) the need for clear professional policies regarding human-subject research, clinical practice standards, and public health goals in human genetics; (3) the need for social policy protection against unfair access to and use of personal genetic information; and (4) the need for improved public and professional understanding and discussion of these issues. The Human Genome Project's goal is to have defined, by 1995, policy options and programs capable of addressing these needs.     

Use of Bait to Increase Archery Deer Harvest in an Urban–Suburban Landscape

Abstract: Hunting is the primary tool for managing white-tailed deer (Odocoileus virginianus) populations. Effectiveness of hunting in suburban areas may be reduced due to limited hunter access to small properties, firearms-discharge laws, and public safety concerns. In Connecticut, USA, hunting over bait on private land was recently legalized to increase harvest opportunities. Our objective was to assess bow-hunter willingness to use bait and effects of bait type, hunter disturbance, time spent hunting, and property size on deer-harvest potential in a suburban landscape. We mailed a prebaiting survey in February 2002 and a postbaiting survey in February 2004 to the same group of hunters. Hunters using bait were more successful and harvested more deer than hunters using no bait. Hunters using bait on small properties observed similar numbers of deer within shooting range as hunters using bait on larger properties. Hunters using bait met their venison needs, whereas hunters using no bait did not meet their needs. Resource managers should implement strategies that increase hunter success when developing urban deer-management programs for communities.     

Habitat preferences of ptarmigan hunters in Norway

Hunting for willow ptarmigan (Lagopus lagopus) is a popular recreational activity in Norway, but studies of the hunters are limited. While large game management in Norway is based on sound models and research, management of small game hunters and hunting have not been subject to the same rigour. Compared to the extensive body of knowledge about ptarmigan behaviour and habitat preferences, the knowledge base on ptarmigan hunters is very limited. We surveyed the habitat preferences of 3,056 hunters to identify preferred landscape categories using pictures covering a range of landscape types. We also examined to which extent residence types and forms of hunting were related to habitat preferences. Through factor analysis, we identified three categories of hunting habitat; mountain forest, low alpine and high alpine. Mode of hunting is more important than residence status in terms of preferred habitat. Hunters using dogs preferred mountain forest and low alpine habitats more than hunters without dogs. Hunters without dogs had a higher preference than dog hunters for high alpine habitats. Hunters with mixed modes of hunting have wider habitat preferences. Residence status only affects the perception of the mountain forest habitat. The results may have implications for management as land use and place-based meanings are currently changing in many natural and rural landscapes, and hunting needs to be integrated with other recreational uses.     

Observation, objectivity, and the conflict of ideas

The first two terms of this title are clear, representing, respectively, the guiding motto of the Society, and the common thread that unites members with very diverse interests and approaches to the understanding of behavior. Then, the last part of the title is elaborated: the conflict of ideas. This aspect is important both in terms of social values, and in terms of the interests of a scientific society operating in the modern world. Within science, there are forces that weaken genuine scientific discussion, and these need at least to be explicated so that their deleterious effects can be minimized. Finally, it is suggested that although the Society has done well in facilitating oral discussion, there is room for improvement in its readiness to engage in written intellectual conflict.     

Breaking the Social–Non‐social Dichotomy: A Role for Reptiles in Vertebrate Social Behavior Research?

Although social behavior in vertebrates spans a continuum from solitary to highly social, taxa are often dichotomized as either ‘social’ or ‘non‐social’. We argue that this social dichotomy is overly simplistic, neglects the diversity of vertebrate social systems, impedes our understanding of the evolution of social behavior, and perpetuates the erroneous belief that one group—the reptiles—is primarily ‘non‐social’. This perspective essay highlights the diversity and complexity of reptile social systems, briefly reviews reasons for their historical neglect in research, and indicates how reptiles can contribute to our understanding of the evolution of vertebrate social behavior. Although a robust review of social behavior across vertebrates is lacking, the repeated evolution of social systems in multiple independent lineages enables investigation of the factors that promote shifts in vertebrate social behavior and the paraphyly of reptiles reinforces the need to understand reptile social behavior.     

Jean Rouch's ethnographic path

This article considers the multiple influences that have shaped Jean Rouch's ethnographic gaze upon the Songhay people of Niger. Marcel Griaule, Rouch's mentor, undoubtedly influenced his student's ethnographic approach to Songhay. But Rouch was equally influenced, I am convinced, by his direct and unforgettable confrontation with the mysteries of the Songhay world. After a discussion of the methodological and theoretical orientations of the Griaule school, I analyze Rouch's major ethnographic work, La Religion et la magie Songhay, focusing upon how Griaulian epistemology and Songhay realities molded the textual presentation. I then discuss several of Rouch's major films—Les Magiciens de Wanzerbé, The Lion Hunters, Les Maîtres Fous, and Tourou et Bitti, placing them within an ethnographic and epistemological context. This analysis leads to a consideration of Rouch's unrecognized contribution to anthropology.     

The imagination of ‘society’ in measurements of immigrant integration

Abstract

My aim in this contribution is to clarify in which way social scientific measurements of immigrant integration operate as a form of ‘social imagination’, that is, of the routinized and professionalized visualization of social life. Through such measurements, images of ‘society’ are produced that feed into larger social imaginaries. My discussion takes as an example Dutch discourse and research on integration. Crucial to the constitution of society in the Netherlands and many other Western European countries is what I call a culturist discourse that has many similarities to racism. This discourse demarcates the boundaries of society by rendering objectively observable the non-integrated who are considered to reside ‘outside society’. The image of society thereby produced is that of a morally cleansed realm: social problems are relegated to the domain ‘outside society’, consisting of persons in need of integration.     

Prolegomena to a dynamics of ideologies

The paper outlines a possible further development of the suggestion made by the author in his recent book. Ideology is defined here as a verbalized, or at least verbalizable, behavior pattern which may be adopted by society. After a brief discussion of possible classifications of ideologies, a study is made of those ideologies which refer to the question of social and ethical interrelations. Different kinds of ideologies may be represented bybehavior matrices, introduced in the author's book. A uniparametric representation of all such matrices is suggested and discussed. Next the previous results on social imitation are extended to the case ofn different behaviors, each of which is determined by a particular value of a continuously varying parameter. It is shown that, depending on some other social parameters, changes from one ideology to another may proceed either quasicontinuously or definitely discontinuously. The paper concludes with some general speculations on the possibility of applying the above results to a mathematical interpretation of history.     

Collective Factors Reinforce Individual Contributions to Human-Wildlife Coexistence

Conserving large carnivores while keeping people safe depends on finding means for peaceful coexistence. Although large carnivore populations are generally declining globally, some populations are increasing, causing greater overlap with humans and increasing potential for conflict. One method of reducing conflict with large carnivores is to secure attractants like garbage and livestock. This method is effective when implemented; however, implementation requires a change in human behavior. Human-wildlife interaction is a public good collective action problem where solutions require contributions from many and individual actions have effects on others. We used the collective interest model to investigate how individual and collective factors work in concert to influence landowner attractant securing behavior in Montana, USA, in black (Ursus americanus) and grizzly bear (U. arctos) range. We used data from a mail-back survey to develop logistic regression models testing the relative effects of collective and individual factors on landowners' attractant securing behaviors. The most important factor was whether individuals had spoken to a wildlife professional, a reflection of social coordination and pressure. Other collective factors (e.g., social norms [i.e., expectations and behaviors of peers] and the existence of discussion networks [i.e., how much social influence an individual has]) were equally important as individual factors (e.g., beliefs, age, gender) for influencing attractant securing behavior among Montana landowners. This research suggests pathways for wildlife managers and outreach coordinators to increase attractant securing behavior by emphasizing collective factors, such as social norms, rather than appealing exclusively to individual factors, such as risk perception of large carnivores. Furthermore, wildlife agencies would be justified in increasing their efforts to connect with landowners in person and to connect with members of the public who play an important role in discussion networks. This research demonstrates that, even on private lands, collective interests may be a missing and important piece of the puzzle for encouraging voluntary attractant securing behavior and improving wildlife-human coexistence. © 2021 The Wildlife Society.     

Behavioral flexibility in rats and mice: contributions of distinct frontocortical regions

Research examining the contribution of genetics to behavior is increasingly focused on higher order behavioral and cognitive processes including the ability to modify behaviors when environmental demands change. The frontal cortices of mammals, including rodents, subserve a diverse set of behavioral and cognitive functions including motor planning, social behavior, evaluation of expected outcomes and working memory, which may be particularly sensitive to genetic factors and interactions with experience (e.g. stress). Behavioral flexibility is a core attribute of these functions. This review orients readers to the current landscape of the literature on the frontocortical bases of behavioral flexibility in rodent laboratory experiments. Studies are divided into three broad categories: reversal learning, inhibitory learning and set‐shifting. Functional dissociations within the broader scope of behavioral flexibility are reviewed, followed by discussion of the associations between specific components of frontal cortex and specific aspects of relevant behavioral processes. Finally, the authors identify open questions that need to be addressed to better establish the constituents of frontal cortex underlying behavioral flexibility.     

The neurobiology of mammalian parenting and the biosocial context of human caregiving

This article is part of a Special Issue “Parental Care”. Research on the neurobiology of attachment, pioneered by scholars in the generation that followed the discovery of social bonding, examined the biological basis of mammalian parenting through systematic experiments in animal models and their application to theories on human attachment. This paper argues for the need to construct a theory on the neurobiology of human attachment that integrates findings in animal models with human neuroscience research to formulate concepts based on experimental, not only extrapolative data. Rosenblatt's (2003) three characteristics of mammalian parenting – rapid formation of attachment, behavioral synchrony, and mother-offspring attachment as basis of social organization – are used to guide discussion on mammalian-general versus human-specific attributes of parental care. These highlight specific components of attachment in rodents, primates, and humans that chart the evolution from promiscuous, nest-bound, olfactory-based bonds to exclusive, multi-sensory, and representation-based attachments. Following, three continua are outlined in parental behavior, hormones, and brain, each detailing the evolution from rodents to humans. Parental behavior is defined as a process of trophallaxis – the reciprocal multisensory exchange that supports approach orientation and enables collaboration in social species – and includes human-specific features that enable behavioral synchrony independent of tactile contact. The oxytocin system incorporates conserved and human-specific components and is marked by pulsatile activity and dendritic release that reorganize neural networks on the basis of species-specific attachment experiences. Finally, the subcortical limbic circuit underpinning mammalian mothering extends in humans to include multiple cortical networks implicated in empathy, mentalizing, and emotion regulation that enable flexible, goal-directed caregiving. I conclude by presenting a philosophical continuum from Hobbes to Lorenz, which illustrates how research on the neurobiology of attachment can put in the forefront the social-collaborative elements in human nature and afford a new perspective on the mind-brain polarity.     

Big game hunting in New Zealand: per capita effort,harvest and expenditure in 2011–2012

Recreational big game hunters make a significant contribution to conservation through kills of deer, pigs, chamois and tahr. New opportunities for managing recreational hunting through the proposed Game Animal Council underscore the need to understand the implications of potential changes in recreational hunting participation and harvests. Based on a survey of hunters' recall over a year, hunters averaged 15.63 (SEM = 0.58) big game hunts per year, spending 30.53 (SEM = 0.85) days hunting and killing 8.92 (SEM = 0.69) big game animals. Hunters commonly targeted several species on a single hunt, with highly skewed distributions for hunter effort and kills. Mean monthly expenditure on big game hunting items was $296.78 (SEM = $8.95). Results demonstrate that big game hunting is a significant activity in New Zealand, but this varies considerably among hunters with a small number responsible for the vast majority of kills. These are important considerations for future big game hunting management.     

Note on the effect of imitation in social behavior

The discussion given by N. Rashevsky (1949) on the effect of imitation in the mathematical biology of social behavior is generalized by assuming the distributions involved to be normal rather than Laplace distributions, and also by showing how most of the results can be derived without assuming any specific form for the distributions. In particular, it is demonstrated that it is possible, in a sufficiently large population, to have a stable behavior pattern which is quite independent of the desires of the population or of their inherent pattern of response.     

Linking social complexity and vocal complexity: a parid perspective

The Paridae family (chickadees, tits and titmice) is an interesting avian group in that species vary in important aspects of their social structure and many species have large and complex vocal repertoires. For this reason, parids represent an important set of species for testing the social complexity hypothesis for vocal communication--the notion that as groups increase in social complexity, there is a need for increased vocal complexity. Here, we describe the hypothesis and some of the early evidence that supported the hypothesis. Next, we review literature on social complexity and on vocal complexity in parids, and describe some of the studies that have made explicit tests of the social complexity hypothesis in one parid--Carolina chickadees, Poecile carolinensis. We conclude with a discussion, primarily from a parid perspective, of the benefits and costs of grouping and of physiological factors that might mediate the relationship between social complexity and changes in signalling behaviour.     

Promoting hunting tourism in north Sweden: opinions of local hunters

Hunting tourism can help to diversify local economies in rural areas. In northern Sweden, hunting tourism has the potential to counteract outmigration and unemployment, but may entail ecological and social risks. I used a mail survey of 2,110 hunters in rural northern Sweden to assess attitudes toward hunting tourism. Respondents emphasized the importance of hunting to maintain economical, social, and cultural values in the rural areas. Most hunters estimated that game contributed equal or larger amount of meat to their household than meat bought commercially. Few respondents had first hand experience of hunting tourism and they were divided on their attitude towards promoting hunting tourism. Many (46%) were uncertain about their attitude towards hunting tourism; 36% were positive and 18% were negative. Ethical values on using wildlife in hunting tourism and the attitude towards new hunters coming to hunt influenced attitudes on development of hunting tourism. Hunters that were positive to hunting tourism believed that it would create new jobs. Because hunting in Sweden is highly organized and collective, there are no models of hunting tourism adapted to the hunting culture in northern Sweden. The uncertainty of the potential local benefits from a development of hunting tourism should be placed within a research framework, especially in the northernmost parts where governmental undertakings are large and the state can influence land use.     

Application of paternity discrimination by DNA polymorphism to the analysis of the social behavior of primates

Paternity in many primate species cannot be established reliably on behavioral grounds. For instance, Japanese macaques (Macaca fuscata) have a multi-male group structure and promiscuous mating patterns. On the other hand, accurate evaluation of male reproductive success is needed to analyze primate behavior. DNA finger-printing techniques were applied to 2 captive groups of Japanese macaques in the Primate Research Institute of Kyoto University for identification of paternity. Also, mating behavior of a captive group was observed in order to compare the reproductive success of each male with that expected on the basis of his observed mating activity. The number of offspring of full adult males was not related to their social rank although the number of copulations with ejaculation was highly correlated with their social rank. Monitoring of the female sexual cycles from the plasma profiles of gonadotropins and ovarian hormones suggested that males could not choose females at days of ovulation. The results of two-free-ranging wild troops, like those of the captive groups, indicated that high-ranking males could not monopolize the paternity of offspring. The results of paternity discrimination in Japanese macaques were compared with results from patas monkeys (Erythrocebus patas) in a discussion of social structure and male reproductive success. Some aspects of polymorphism detection techniques are also discussed.     

Social influences on foraging in vertebrates: causal mechanisms and adaptive functions

We summarize 20 years of empirical and theoretical research on causes and functions of social influences on foraging by animals. We consider separately studies of social influence on when, where, what and how to eat. Implicit in discussion of the majority of studies is our assumption that social influences on foraging reflect a biasing of individual learning processes by social stimuli rather than action of independent social-learning mechanisms. Our review of theoretical approaches suggests that the majority of formally derived hypotheses concerning functions of social influence on foraging have not yet been tested adequately and many models are in need of further refinement. We also consider the importance to the future of the field of integrating 'top-down' and 'bottom-up' approaches to the study of social learning.

Treatment implications of comorbid psychopathology in American Indians and Alaska Natives

This paper discusses treatment implications of comorbid psychopathology in the context of American Indian and Alaska Native culture and in the context of the Indian Health Service's Mental Health and Alcohol and Substance Abuse Program Branches. Treatment of comorbidity in this population is a particularly difficult problem due to numerous barriers to treatment and a poorly defined treatment system. As in other clinical populations, these patients are high utilizers of the limited treatment services available, but may not receive the type of treatment they need. After describing the extent of comorbidity in this population, we present an historical perspective of mental illness that provides an Indian's view of why we are where we are today in treating these problems. Next, we discuss Western and traditional treatment implications for comorbidity among adults and adolescents. Finally, we suggest directions for future research in this area.
