Connecting with Country in Mungo National Park,Australia: a case study to measure the emotional dimension of experience and place attachment

Connecting people with nature improves well-being, but how people connect with natural places is not well documented. We asked 43 people (19 Aboriginal Australians, 24 non-Aboriginal people) about the messages they received from Country during an interactive experience in the remote Mungo National Park, Australia, and analysed the physical senses, emotions and cognitive processes they mentioned. The physical senses mentioned by most respondents were sight, hearing and motion (particularly walking). These senses helped people receive messages from Country and connect with place. We used the primary-process emotional systems of Panksepp [2010. Dialogues in Clinical Neuroscience, 12 (4), 533–545] as a framework to capture the emotional dimension of experience. Most people reported positive emotions; they spoke about being nurtured by the group and the land (CARE), and the intense joy (PLAY) of being part of the community, being on Country and being accompanied by Aboriginal people. However, our results indicate the framework does not capture the breadth of positive emotions, particularly those associated with connection to place and spiritual experiences. Both groups mentioned cognitive processes reflecting their beliefs, existing knowledge, or sharing and acquiring new knowledge. Our results indicate that the emotional dimension of experience has the potential to measure connection to place, and provide a subjective measure of well-being. More research is needed to document this dimension of experience, and how it changes with context. Our case study provides further insight for those who manage protected areas and seek to enrich the experience of visitors.     

The effects of variable predation risk on foraging and growth: less risk is not necessarily better

There is strong evidence that the way prey respond to predation risk can be fundamentally important to the structuring and functioning of natural ecosystems. The majority of work on such nonconsumptive predator effects (NCEs) has examined prey responses under constant risk or constant safety. Hence, the importance of temporal variation in predation risk, which is ubiquitous in natural systems, has received limited empirical attention. In addition, tests of theory (e.g., the risk allocation hypothesis) on how prey allocate risk have relied almost exclusively on the behavioral responses of prey to variation in risk. In this study, we examined how temporal variation in predation risk affected NCEs on prey foraging and growth. We found that high risk, when predictable, was just as energetically favorable to prey as safe environments that are occasionally pulsed by risk. This pattern emerged because even episodic pulses of risk in otherwise safe environments led to strong NCEs on both foraging and growth. However, NCEs more strongly affected growth than foraging, and we suggest that such effects on growth are most important to how prey ultimately allocate risk. Hence, exclusive focus on behavioral responses to risk will likely provide an incomplete understanding of how NCEs shape individual fitness and the dynamics of ecological communities.     

Sustainable Development: The Need for a New Paradigm

At present, the term sustainable development is misleading because we actually live in a markedly unsustainable world and conditions will become even more unsustainable in the 21st century. Indeed, the 21st century will be the defining period in man's occupation of this planet. Either we take very positive steps to ameliorate our environmental excesses now or we face the prospect of major environmental catastrophes in the future. It is a fact that advanced civilizations have collapsed twice within the last 5000 years in Europe and we must face up to the fact that a third collapse, this time on a global scale, is not beyond the realms of possibility. It is therefore up to us to begin using our considerable ingenuity to prepare for the future in a more rational manner than is presently the case. This article demonstrates clearly the dilemma that we now face.     

From disaster management to adaptive governance? Governance challenges to achieving resilient food systems in Australia

Building resilient food systems in the context of climate change and increased natural disasters depends on governance being more ‘adaptive’. Through a case study of events surrounding the extensive flooding that occurred in Queensland, Australia, in 2011, this paper examines how governance settings and processes affected food system actors’ engagement with three aspects of adaptive governance – responsibility, participation and collaboration – as those actors sought to ensure food availability and access during the crisis. We found that, despite the existence of formal governance instruments committed to disaster management, food security and resilience at local, state and national levels, responsibilities for ensuring food supply during a disaster were not clearly articulated. Responsibility was largely assumed by supermarkets, who in turn increased the influence of retailer–government coalitions. The participation of non-supermarket food system actors in governance was low, and there was limited collaboration between local, and other, levels of governance. The policy challenge is to ensure that responsibility, participation and collaboration become a stronger foci for adaptive governance during and after a disaster such as flooding.     

The role of size and aggression in intrasexual male competition in a social lizard species, Egernia whitii

Competition between males is a key component of the agonistic intrasexual interactions that influence resource acquisition, social system dynamics, and ultimately reproductive success. Sexual selection theory predicts that traits that enhance success in intrasexual competition (particularly male–male competition) should be favored. In vertebrates, this often includes body size and aggression, with larger and/or more aggressive males outcompeting smaller or less aggressive conspecifics. The majority of studies consider aggression as a flexible trait which responds to local social or environmental conditions. However, aggression frequently shows considerable within-individual consistency (i.e., individuals have identifiable aggressive behavioral types). Little is known about how such consistency in aggression may influence competition outcomes. We integrated a detailed field study with a laboratory experiment to examine how a male’s aggressive phenotype and his size influence competitive interactions in Egernia whitii, a social lizard species which exhibits strong competition over resources (limited permanent shelter sites and basking sites). Individual aggression and size did not predict competition outcome in the laboratory nor did they predict home range size, overlap, or reproductive success in the field. However, winners of laboratory trial contests maintained consistent aggressive phenotypes while consistency in aggression was lost in losers. We suggest that aggression may be important in other functional contexts, such as parental care, and that alternative traits, such as fighting experience, may be important in determining competition outcome in this species.
