Invasive species or species of conservation concern are embedded in ecological networks of interactions. Single species management actions directly affect the target species, and can also have direct off-target effects on co-occurring species (e.g. pesticide spray drift or soil disturbance). Changes in abundance of the target species due to management also have the potential to affect other species which interact with the target, these are termed indirect effects of management. We are interested in assessing the risks of indirect effects of management through analysis of food-webs and the management levers available. We are working on how to allocate resources to management which will maximise our conservation objectives but minimise undesirable indirect effects. We are also working on prediction of how changes in target species abundance affect network properties. We are currently working with case-study systems of trophic interactions in Christmas Island, Anarctica, sub-Antarctic islands and plant pollinator networks in the UK.

My research revolves around decision theory and decision science. While I am interested in all forms of environmental decision-making my recent work falls into two key areas – monitoring and adaptive management and the management of multiple interacting species (see below for more details). As a NERP researcher I am keen on infusing a structured and explicit approach to decision-making into environmental problems. NERP colleagues and I run workshops on structured decision-making, and I also facilitate the decision process for individual problems within SEWPAC. Email me to discuss getting assistance with a particular decisions problem, or you are interested in my work on monitoring, adaptive management or the management of multiple species and threats.

Dr Justine Shaw

Web page

Justine Shaw is a postdoctoral fellow researching conservation decision making in the terrestrial Antarctica and sub-Antarctic, with a particular focus on non-native species. Her position is a collaborative one between EDG, the University of Queensland and the Australian Antarctic Division. Justine is currently examining the risks posed by non-native species to Antarctic protected areas, examining the interactions between indigenous and non-native species, and investigating how invasive species influence ecosystem function. Justine is interested in the role of invasive vertebrates as drivers of invasive plant distribution and abundance, and how these change over time, space and management regimes. She is interested in ways of dealing with uncertainty in large scale eradication attempts.

Ayesha is a conservation biologist interested in monitoring and management of threats to biodiversity. She integrates disciplinary perspectives (economic, social, political and environmental) to evaluate approaches for prioritising conservation investments in multiple stakeholder landscapes. Ayesha has a particular interest in invasive and mobile predators, network theory, return on investment, migratory species and bird ecology.

Ayesha is currently working on tools and approaches for prioritising investment in management and monitoring of multiple species and threats, with a focus on applying decision-making software for systematic conservation planning and cost-effectiveness analysis to choose between actions for species recovery, and incorporating uncertainty in management outcomes and risk aversion into ...
