An overview of commercial fishers’ attitudes towards marine protected areas

Marine protected areas (MPAs) are attracting widespread attention worldwide as a tool for fishery management and marine ecosystem conservation. The establishment of MPAs has increased greatly in recent years mostly due to international commitments to the establishment of a global network of MPAs by 2012. MPAs have the potential to strongly affect the fishing industry, and their success depends, at least partly, on fishers’ attitudes towards this management measure. However, research on MPAs tends to focus on the ecological and conservation aspects of this management approach and not on its human dimensions. Studies in attitudes, perceptions, beliefs and preferences related to MPA issues have been identified as priority social science topics in need of research. We present a ‘rapid review’, conducted systematically, of the literature published up to September 2009 and aimed at identifying the most investigated topics related to commercial fishers’ attitudes towards MPAs, describing the main findings from these studies, and analysing the implications for management. Most published work focuses on fishers’ attitudes towards issues of governance, conservation of biodiversity and the environment, and the impact of MPAs on fishing activity. Despite the recent increase in the literature on the human dimensions of MPAs, the present review reveals that little of this literature originates from empirical studies. Hence, given the forthcoming increase in the implementation of MPAs in the near future, research on fishers’ attitudes towards these management measures is critically needed.     

Wildlife value orientations and demographics in The Netherlands

This article identified the Dutch publics’ value orientations toward wildlife and examined differences in value orientations among four demographic characteristics: age, sex, current residence, and education. The two wildlife value orientations—domination and mutualism—were based on prior theorizing and research in the USA. People with a domination value orientation believe wildlife should be managed for human benefit and are more likely to prioritize human well-being over wildlife in their attitudes and behaviors. Individuals with a mutualism orientation view wildlife as part of an extended family, deserving of rights and care. Data were obtained from a mailed survey (n = 353) sent to randomly selected individuals in the Dutch population. K-means cluster analysis was used to segment respondents into three groups based on their responses to the 19 items used to measure their wildlife value orientations. As predicted by the literature, those with a domination wildlife value orientation were statistically older (M = 55.2) than mutualism oriented individuals (M = 51.5). Females (61%) and those living in an urban area (48%) tended to be more mutualism-oriented. There were no significant differences among the clusters in education level. Overall, this article provides information about wildlife value orientations and public demographic characteristics that can help wildlife managers to (1) understand the diversity of value orientations that exist and (2) gauge support for or opposition to management policies.     

Collective Titling and the Process of Institution Building: The New Common Property Regime in the Colombian Pacific

This research is an empirical examination of institutional developments in Afro-Colombian communities that have occurred since the change in the property rights regime in 1991. I surveyed 82 local leaders of 42 communities to understand whether these communities have succeeded in designing and implementing rules to manage their collective land and its resources. I found that the new property regime has not replaced individuals’ informal land holdings, which are still managed as de facto individual private property and are traded in the informal land market. However, the process of collective titling has changed local environmental governance by creating local rules and legal tools to guard against encroachment by intruders. Beyond the establishment of formal property rights, the process of community and authority building based on the expectation of collective titling has begun to formalize the management of the territory. Communities with and without collective titles have promoted new rules and procedures to manage their resources. However, monitoring and enforcement of the rules are weaker than expected.     

Sexual selection and physical attractiveness

Sexual selection processes have received much attention in recent years, attention reflected in interest in human mate preferences. Among these mate preferences are preferences for physical attractiveness. Preferences in and of themselves, however, do not fully explain the nature of the relationships that individuals attain. A tacit negotiation process underlies relationship formation and maintenance. The notion that preferences for physical attractiveness evolved under parasite-driven “good genes” sexual selection leads to predictions about the nature of trade-offs that individuals make between mates’ physical attractiveness and investment potential. These predictions and relevant data are explored, with a primary emphasis on women’s preferences for men’s qualities. In addition, further implications of trade-offs are examined, most notably (a) the impact of environmental variations on the nature of mating and (b) some effects of trade-offs on infidelity and male attempts to control women. The ideas in this paper were substantially influenced by discussions with Kim Hill and Hilly Kaplan following a preliminary presentation of work contained herein at a UNM Human Evolutionary Ecology Program colloquium. Steven W. Gangestad is an associate professor of psychology at the University of New Mexico. His recent research includes work focused on sexual selection in humans and its implications for general relationship phenomena. His other recent research concerns the impact of developmental instability on functional asymmetries, interpersonal orientations, and individual differences in the control of emotional expression.     

Things We Like: Human Preferences among Similar Organisms and Implications for Conservation

Human preferences will increasingly determine many species’ prospects for survival. However, aside from a small number of survey-based studies of preference among disparate taxa, human species preferences have received little attention. I determined human aesthetic preferences among a relatively homogenous group, the penguins, from representation in all recently published, comprehensive, popular books of photographs of penguins (n = 4 books; 304 photographs). Representation of visually distinguishable types of penguins, measured by total photograph area, was highly skewed and rankings were highly concordant across books, suggesting large and commonly held differences in aesthetic appeal. Multiple regression analysis indicated that amount of warm color was the only significant determinant of representation, and warm color was highly correlated (r ² = 0.96) with mean representation of the penguin types. Body size and neotenic form, traits found to influence human preferences among other animals, were not significant, suggesting that the bases of human species preferences differ by species type. The results of this study indicate that human aesthetic preferences discriminate finely among species and may be based on minor features. Conservationists must be vigilant to the potential for aesthetic responses to influence conservation efforts.     

Exploring the Relationships among Epistemological Beliefs, Nature of Science, and Conceptual Change in the Learning of Evolutionary Theory

We explored the relationship between epistemological beliefs and nature of science in a college biology course. One hundred thirty-three college students participated in the research. Exploratory factor analysis with 29 Nature of Science (NOS) items yielded three aspects of NOS: empirical, tentative, and sociocultural nature of scientific knowledge. Pearson r correlations suggested that students who have immature epistemological beliefs are more likely to also have immature beliefs of nature of science. In addition, students’ epistemological beliefs significantly correlate with their conceptual change but their beliefs about nature of science did not. The research is significant in that it provides empirical evidence explaining the relationship between students’ epistemological beliefs and nature of science as well as the relationships between epistemological beliefs and conceptual change in evolution theory.     

Minimizing the Livelihood Trade-Offs of Natural Resource Management in the Eastern African Highlands: Policy Implications of a Project in “Creative Governance”

The highlands of Eastern Africa are characterized by high population densities and tightly coupled interactions between adjacent landscape units and users. Effective formal or informal natural resource governance is necessary to mitigate the potential negative social and environmental effects of individuals’ behavior. Yet many natural resource management and development problems that require or benefit from collective solutions remain unresolved (German et al. Environ Dev Sustain 8: 535–552, 2006a; German et al. 2006b; German et al. Q J Int Agr 47(3): 191–216, 2008). We argue that many of the more intractable problems in improving governance stem from the trade-offs that underlie them, which may include a loss of livelihood options for at least some households, leading to governance break down. Following a brief introduction to natural resource management and governance in Eastern Africa, we analyze the results of participatory by-law deliberations by distilling the restrictions proposed governance reforms pose to certain local stakeholders. We recommend that future policy for improved landscape governance couple institutional reforms with livelihood alternatives that reduce the burden of good governance on households.     

Attitudes and perceptions of patients towards methods of establishing a DNA biobank

Background This study aimed to assess patient attitudes as part of the planning process for a large-scale effort to collect genetic samples for research from excess clinical blood specimens (‘DNA Databank’ project). Method A pre-tested, 38-item questionnaire was mailed to a random sample of 5,000 inpatients, outpatients, and emergency department patients. Results Approximately 20% of patients responded (n = 1003). Most were comfortable with anonymized genetic information being used for research (89.3%) and supported the potential benefits (98.7%). A binary logistic regression on the level of comfort with the DNA program shows that the variability in respondents’ feelings about the program can best be explained by beliefs, age, and health status. Respondents were attitudinally segmented into 5 distinct categories. Conclusions These data indicate general acceptance among respondents, but a subset of the population would be opposed to the program. This reinforces the need to broadly and continuously communicate with patients about the program and the ability to exclude a given sample. The effects of prior beliefs would benefit from further exploration.     

Animal Preferences and Acceptability of Wildlife Management Actions around Serengeti National Park, Tanzania

Wildlife management policies are often based on expert perceptions of the ecological importance of certain species and poorly informed perceptions of how public attitudes toward management are formed. Little is known about why preferences vary greatly and how this affects support for management actions. This paper explores preferences for a range of wildlife species among a sample of the rural population adjacent to Serengeti National Park in Tanzania. We also examine the degree of acceptance for alternative management interventions when potentially dangerous animals pose different levels of problems to human beings, and the extent to which these attitudes are related to species preferences. Gender has a significant effect on species preferences. Men like most species better than women. Age has no significant effect, but level of education affects preference level for some species. Species preferences have a positive effect on support for management intervention when dangerous animals cause small or moderate problems to humans, i.e. there is a higher degree of acceptance of problems caused by animals that are well liked. In situations where human life is threatened, species preferences have no effect on preferred management actions. Appreciation of animals is a combination of functional, consumptive and cultural dimensions, and there is no simple link between species preferences and attitudes toward management actions. The local context and concrete experience with wildlife encounters is more important for shaping normative beliefs like attitudes towards management actions than global wildlife attitudes.     

Analysis of callouts made in relation to wild urban marmosets (Callithrix penicillata) and their implications for urban species management

In this study, we investigated what problems urban marmosets (Callithrix penicillata) face in a city environment through the analysis of responses to callouts (N = 348) made by the environmental police of Belo Horizonte, Minas Gerais, Brazil, in the period from 2002 to 2007. Our objective was to characterise the problems faced by the marmosets and human city dwellers. The environmental police responded to two types of callouts: (1) solicitation whereby a person called them to report a problem (N = 218); and (2) the report of a hurt or injured animal (N = 127). On average, one callout per week was made in relation to urban marmosets. We found no time of year effects in relation to callouts, or any effect of gender or age of the person making the callout (P > 0.05). Furthermore, we found no environmental (e.g. percentage of “green area”) or socioeconomical variables (e.g. salary levels) of the city’s administrative regions associated with callouts (P > 0.05). The majority of callouts resulted in the attempt to capture marmosets (N = 345), and usually, only one animal was captured (N = 309). Many of these animals were released into city forest fragments (N = 146). Some sick animals were sent to veterinary clinics (N = 25) whereas others or confiscated animals were sent to the government’s wildlife processing centre (N = 143). From this data, we were able to make a series of recommendation about how the management of urban marmosets could be improved.     

Ecoethics: Now Central to All Ethics

A few years ago, I wrote on the need for expansion of the environmental areas of bioethics, and covered some of the topics touched on here. Sadly, although it is possible to find some notable exceptions, bioethics does not provide much of an ethical base for considering human-nature relationships. Here I’m not going to deal with these philosophical issues or others about the nature of ethical decision-making. The rapid worsening of the human predicament means that applied ethical issues with a significant environmental connection (what I call “ecoethics”), must be dealt with without waiting for the more interesting theoretical issues to be resolved. I define ecoethics very broadly to deal with dilemmas over a vast range of scales, and believe they now should penetrate virtually all areas of human activities. Ecoethics must struggle with issues of intra-generational (and interperson/group/nation) equity and the dilemmas of discounting by distance (valuing distant persons/events/costs/benefits less than those closer to the observer in physical or mental distance). Ecoethics also deals with the difficult dilemma of inter-generational equity—of discounting the future. That is especially troublesome when actions today can have significant environmental consequences 50 or more generations from now. Here I would like to highlight the ubiquity of those questions and the importance of seeking answers.     

Ecology of the North Sea: Problems,successes, failures,future needs

After defining ‘ecology’, outlining the basic categories of ecological research and listing examples of modern ecological investigations, this introductory paper focusses on basic considerations; it is, in essence, a programmatic contribution. Research details on the ecology of the North Sea are the subject of the following papers. Theproblems of ecological North Sea research are formidable. Hydrological and biological fluctuations and variabilities are pronounced. Exchange patterns with the Atlantic are complex, and the inputs of rivers and rain defy exact measurement and prediction. Season, weather, climate—and as yet insufficiently known and controlled human-caused impacts—further complicate the situation. All this results in an unusually high degree of uncertainty. New questions and problems arise before the old ones can be answered or solved. Nevertheless, ecological North Sea research has achieved manysuccesses. The North Sea is the most intensively investigated sea area on our planet. Generations of zoologists, botanists and hydrographers — and more recently microbiologists, meteorologists, climatologists, chemists, pathologists and toxicologists — have produced an impressive body of knowledge. Slowly we are beginning to understand the forces that govern energy budgets and balances, material fluxes, and the factors that control and direct ecosystem dynamics. Essential driving forces of ecosystem dynamics result from microbial, especially bacterial, activities. Ecological modelling has paved the way for new theories and insights, and holds promise for progress towards a predictive ecology.Failures and shortcomings include insufficient long-term research, inadequately designed experiments, and misconceptions in environmental protection. Net changes in ecological processes of an heterogeneous and intensely varying environment such as the North Sea can only be comprehended adequately against the background of sustained measurements over decades.Future needs include: more long-term research; and new patterns of management, institutional organization and financial support. Essential breakthroughs in field-work demand more teamwork, in-situ experimentation and surveys from space. Studies on the health status of organisms and ecosystems should receive more attention. Finally, there is need for changes in human behaviour: we must use our insight and willpower to meet the deadly consequences of our self-made scientific-technological evolution by an equally self-made ethical evolution aimed at achieving a re-harmonization with nature.     

Estimating economic values of vegetation restoration with choice experiments: a case study of an endangered species in Lake Kasumigaura, Japan

As the pace of ecosystem restoration increases, more attention has been directed towards understanding public preferences for ecosystem restoration projects. This paper utilizes a choice experiments technique to evaluate the restoration project of an endangered species, Nymphoides peltata (known locally as asaza) in Lake Kasumigaura, Japan. The restoration project evaluated in this paper consists of two attributes: an extinction risk and a lakeshore ecosystem. First, we observe a positive willingness-to-pay for the vegetation restoration project: the mean willingness-to-pay for restoring the endangered specie and avoiding extinction was about JPY6,800 and the mean willingness-to-pay for restoring the covering area to the ideal condition that the species originally inhabited in 1996 was about JPY1,600. Second, we clarify what kinds of individual characteristics affect preferences for restoration projects compared with preferences for the status quo. The results show that respondents who have strong environmental attitudes, visit experience, high income, and are female are more likely to prefer restoration projects to the status quo. Third, we investigate whether knowledge and comprehension of ecological information have any influence on respondents’ value formations. We find that respondents’ comprehension of ecological information is positively related to their willingness-to-pay for the avoidable level of extinction risk attribute, while respondents’ knowledge of ecological terms has no effect. Overall, our findings suggest that the public strongly desires the avoidance of extinction of endangered species, and indicates that researchers should be careful about how ecological information is given.

Links between ecology and ecophilosophy,ethics and the requirements of environmental management

Abstract This paper concerns the ways that our philosophical attitudes to the environment can influence the appropriateness of methodologies for solving environmental problems. Sometimes a public perception is expressed that science takes scant regard of the concerns of the people affected. Is it possible for scientists and managers to respond to such concerns and still fulfil the logical and methodological rigour that their discipline demands? I believe we have to address fundamental issues of definitions and meaning before useful debate can occur among parties interested in environmental decision-making. Delving into the ideas behind our everyday practices of environmental management should promote re-evaluation of our beliefs, attitudes and concerns about nature. I examine environmental science from both ethical and managerial perspectives. I explore how our assumptions and attitudes might influence ecology, in particular issues raised by environmental impacts and conservation. The major points argued here are:

• 1 Any legal requirements of environmental investigations must be met, but perhaps we should act more in line with the spirit of legislation.
• 2 The managerial imperatives of environmental investigations need to be examined closely because of widely perceived problems with the use of science in impact assessment. We must change either our methods of assessment or the regulations and administration of environmental impact assessment (EIA).
• 3 Science is not paramount in the processes of environmental decision-making. We need to be aware of how psychosocial factors affect the ultimately political decisions about environmental problems.
• 4 Philosophy and ethics offer a range of perspectives that may benefit ecology. Scientists need to be aware of these just as they should be of their own leanings about how we treat nature.
• 5 Scientists need to translate social concerns or demands about the environment into properly defined scientific questions, and then study them as a matter of urgency.
• 6 Ecology needs to guide ecophilosophers and environmental ethicists as to how nature works, why we expect variability in ecosystems, what is naturalness, and other issues where a scientific understanding of nature has progressed beyond the point where these observers of ecology have so far taken inspiration.

     

Xylan degradation: a glimpse at microbial diversity

The key to taking the measure of biodiversity lies in a downward adjustment of scale. . .Most of the Earth’s largest species—mammals, birds, and trees—have been seen and documented. But microwildernesses exist in a handful of soil or aqueous silt collected almost anywhere in the world. . .Bacteria, protistans, nematodes, mites and other minute creatures swarm all around us, an animate matrix that binds the Earth’s surface.

Conservation implications of competition between generalist and specialist rodents in Mediterranean afforested landscape

Density dependent habitat selection at the community level is regarded as a major determinant of biodiversity at the local scale, and data on these processes and how they are affected by human activities is highly applicable to conservation. By studying the competitive relationships between a specialist and a generalist we can acquire valuable insights about how different environmental elements determine species abundance and distribution and consequently biodiversity. Here we describe a study of density dependent processes that determine the community structure of two rodents: a specialist—the broad toothed mouse (Apodemus mystacinus), and a generalist—the common spiny mouse (Acomys cahirinus) in a Mediterranean maqui habitat, and how this structure is impacted by anthropogenic planting of pine stands. We carried out two field experiments: The first, based on open field trapping, looking at how rodent communities change with habitat structure. The second experiment was an enclosure study aimed at validating the habitat preferences and competitive relationship between the specialist and the generalist. We identified asymmetric competition relationships in which the specialist was dominant over the generalist. Competition intensity was lower in maqui with >10% oak cover, although both species abundances were high. Competition was found only during the limiting season (summer). Based on these findings we produced management recommendations to keep indigenous small mammals’ biodiversity high. Density dependent habitat selection processes play a central role in determining biodiversity, and understanding the mechanisms motivating these processes is needed if alterations in biodiversity in response to human disturbance are to be understood.     

Living a Fast Life

The current research applied a mid-level evolutionary theory that has been successfully employed across numerous animal species—life history theory—in an attempt to understand the Dark Triad personality trait cluster (narcissism, psychopathy, and Machiavellianism). In Study 1 (N = 246), a measure of life history strategy was correlated with psychopathy, but unexpectedly with neither Machiavellianism nor narcissism. Study 2 (N = 321) replicated this overall pattern of results using longer, traditional measures of the Dark Triad traits and alternative, future-discounting indicators of life history strategy (a smaller-sooner, larger-later monetary dilemma and self-reported risk-taking behaviors). Additional findings suggested two sources of shared variance across the Dark Triad traits: confidence in predicting future outcomes and openness to short-term mating.     

A proposal for re-defining the way the aetiology of schizophrenia and bipolar human psychiatric diseases is investigated

“The two big problems — the nature of development and the nature of the mind — are being subdued. I don’t know whether there will be beautiful, general theories to come out of this — something really nice like Watson and Crick’s double helix — or whether there will be an accumulation of more and more details. I’ll confess to a secret hope for the former” (Crow 2000).     

Common names of species, the curious case of Capra pyrenaica and the concomitant steps towards the ‘wild-to-domestic’ transformation of a flagship species and its vernacular names

Common names (CN) add to linguistic richness and ultimately derive from how a majority of people refer to a species. CN have a biological and–above all—practical importance given that they are essential for connecting specialists and lay people. To illustrate the diversity of CN between and within species, we made an overview of common name in Caprinae species—flagship species in mountain ecosystems. Then, using Capra pyrenaica as a study case, we highlighted that the choice of CN is inextricably linked to current debates and trends in wildlife management that should never be ignored, given their importance in the fields of ethics, zoology, systematics, conservation and current management. We underline the need to investigate further the probable relationships linking common names, human perception and wildlife management. Researchers, citizens and policy-makers will have to be watchful that clumsy common names, such as ‘wild-to-domestic’ transformed ones, will not hamper the conservation of wild species as a ‘Common Heritage’.     

Technological biology? Things and kinds in synthetic biology

Social scientific and humanistic research on synthetic biology has focused quite narrowly on questions of epistemology and ELSI. I suggest that to understand this discipline in its full scope, researchers must turn to the objects of the field—synthetic biological artifacts—and study them as the objects in the making of a science yet to be made. I consider one fundamentally important question: how should we understand the material products of synthetic biology? Practitioners in the field, employing a consistent technological optic in the study and construction of biological systems, routinely employ the mantra ‘biology is technology’. I explore this categorization. By employing an established definition of technological artifects drawn from the philosophy of technology, I explore the appropriateness of attributing to synthetic biological artifacts the four criteria of materiality, intentional design, functionality, and normativity. I then explore a variety of accounts of natural kinds. I demonstrate that synthetic biological artifacts fit each kind imperfectly, and display a concomitant ontological ‘messiness’. I argue that this classificatory ambivalence is a product of the field’s own nascence, and posit that further work on kinds might help synthetic biology evaluate its existing commitments and practices.
