The return of the ‘beast’?

We (Tanja and I) just published a new conservation conflict exploration on our Medium blog!

We asked three experts from the fields of Human Dimensions, Wildlife Research and Moral Philosophy to share their perspectives with us on a particular case study:

Germany relaxes rules on shooting wolves

“After a emotional debate pitting environmental against farming concerns, the government decided that wolves can now be shot if they cause “serious damage” to livestock farmers.

In cases of repeated attacks against sheep flocks or cattle herds, individuals can be hunted down even if it is unclear which animal in a pack was responsible.”

We asked the experts:

  1. Why do people struggle so much with the return of wolves?
  2. Should killing of wolves in Germany be allowed/legal?
  3. What would be the best first step(s) to address this conflict in Germany or other countries in similar situations?

Culling hyenas to save horses

We (Tanja and I) just published our very first conservation conflict exploration on our Medium blog!

We asked three experts from the fields of Human Dimensions, Wildlife Research and Moral Philosophy to share their perspectives with us on a particular case study:

Namibia starts controversial hyena cull to save its wild horses

“Shooting hyenas to save wild horses raises heated debate about whether conservation authorities should intervene between endemic wildlife and ‘feral’ animals.”

We asked the experts:

  1. What approach would you recommend decision-makers to take to best address this conflict?
  2. Why this approach (e.g. which processes, perspectives or values should be prioritized in your view)?
  3. What should be the first step?

Exploring Conservation Conflicts

“The art and science of asking questions is the source of all knowledge” – Thomas Berger –

Tanja Straka and I like asking questions. Even more so, we like animals, nature and people. Unfortunately, these three do not always mix well and we want to learn why.

Coming from our respective backgrounds in social sciences and animal sciences, we want to learn about the ins and outs of wildlife conservation conflicts by exploring different perspectives. Because we are convinced that understanding the diverse aspects of conservation conflicts could also open our minds to a diversity of (new) ways to address them.

With that in mind, we are keen to explore Conservation Biology and Animal Behaviour (Ethology), Moral Philosophy (Ethics) and the Human Dimensions of Wildlife (Social Sciences) and their perspectives on real-life conservation conflict situations.

In a blog on Medium (and on Twitter), we would like to share the different viewpoints we encounter in our daily lives and work and to invite people to share their perspectives.

Connect to us and let’s explore together!

New publication: Systematic reviews and maps as tools for applying behavioral ecology to management and policy

Yeah! Our recent open access paper on systematic maps and reviews in behavioural ecology is now available in, how appropriate, Behavioral Ecology. It is the first concrete output of a group of behavioral ecologists, passionate to effectively contribute to wildlife conservation. This is just the beginning! Many thanks to Oded Berger-Tal, Alison Greggor and Dan Blumstein for bringing us all together.

Paper_head

Summary of the paper:

Although examples of successful applications of behavioral ecology research to policy and management exist, knowledge generated from such research is in many cases under-utilized by managers and policy makers. On their own, empirical studies and traditional reviews do not offer the robust syntheses that managers and policy makers require to make evidence-based decisions and evidence-informed policy.

Similar to the evidence-based revolution in medicine, the application of formal systematic review processes has the potential to invigorate the field of behavioral ecology and accelerate the uptake of behavioral evidence in policy and management. Systematic reviews differ from traditional reviews and meta-analyses in that their methods are peer reviewed and prepublished for maximum transparency, the evidence base is widened to cover work published outside of academic journals, and review findings are formally communicated with stakeholders. This approach can be valuable even when the systematic literature search fails to yield sufficient evidence for a full review or meta-analysis; preparing systematic maps of the existing evidence can highlight deficiencies in the evidence base, thereby directing future research efforts.

To standardize the use of systematic evidence syntheses in the field of environmental science, the Collaboration for Environmental Evidence (CEE) created a workflow process to certify the comprehensiveness and repeatability of systematic reviews and maps, and to maximize their objectivity. We argue that the application of CEE guidelines to reviews of applied behavioral interventions will make robust behavioral evidence easily accessible to managers and policy makers to support their decision-making, as well as improve the quality of basic research in behavioral ecology.

Key words: applied animal behavior, conservation behavior, evidence-based management, literature review, meta-analysis, policy impact, systematic maps.

Conservation behaviour

How can a behavioural ecologist contribute to conservation? It is a question I often ask myself. Therefore I am very happy to have become part of a team of behavioural ecologists that asks the same question. Together we followed a workshop by Mistra EviEM on how to conduct a systematic map or review and are now answering questions about the effectiveness of conservation interventions. In our case, behavioural interventions.

It is not an easy challenge, to gather and review all the literature that is out there on a given intervention, academic and grey. But, without a good overview of the best evidence available, how are we going to stop ourselves from doing the same thing over and over again? Are certain interventions effective, also on the long-term, or not at all? Are there certain conditions to be met for them to be of use?

I set out to answer these questions for an intervention in a very urgent and increasingly bigger conservation challenge: Human-Wildlife-Conflict (HWC). More specifically, I will map and review studies on the effectiveness of conditioning-interventions in reducing HWC with vertebrate carnivores. In other words Can carnivores be taught to stay away?

It will be a long, challenging, but useful task and I am very keen to work on it!

New publication: Linking animal social network theory to conservation

Available for free until September 7, 2017Click this link

Last week, June 22, a for me very important paper was published online in the scientific journal Trends in Ecology and Evolution. With this Opinion paper, me and my co-authors hope to stimulate a closer collaboration between animal social network scientists and conservation practitioners. You can read more about it in our press release below. If you are interested in reading the complete scientific article, but do not have access, please send me a message/email. 

As with humans, most animals prefer to associate with some individuals and not with others. The social structure can influence how a population responds to changes in its environment. Examining social networks is a promising technique for understanding, predicting and – if for the better – manipulating this structure. However, whereas the contribution of behavioural biology to conservation is already well recognized, the usefulness of animal social network analysis as a conservation tool has not yet been addressed. A group of behavioural ecologists led by Lysanne Snijders from the Leibniz-Institute of Freshwater Ecology and Inland Fisheries (IGB) outlines how the understanding of relationships between animals could be applied by wildlife managers and conservationists to support their work in disease management, breeding programs, reintroductions or relocations, or for controlling problem behaviours – to name just a few.

Animal social network studies examine how the individuals of a population are socially connected, how they interact and associate. Knowledge of the social structure can help to identify the flow of information or the spread of disease, and has potential to be used as an indicator of upcoming population changes. Information of that kind would be less – or not at all – noticeable using methods purely based on population size or the observation of single individuals.

Dr Lysanne Snijders, Post Doctoral Researcher at the Department of Biology and Ecology of Fishes at IGB, describes this approach with the help of Aristotle: “The whole is greater than the sum of its parts. Combined effects of social interactions in wildlife populations do not only have important theoretical but also practical implications. Linking animal social network theory to practice can therefore stimulate the design of new practical conservation tools and generate novel insights into how animal social networks change over time.”

An example from real wildlife

For many species, it is not just diseases that can spread rapidly. Social information can also be transmitted via various routes within a group, for instance, innovative ways to search for food. In the case of the California sea lion, novel foraging strategies have led to conflict with a fishery conservation scheme. The sea lions had discovered that salmonids migrating upriver became more concentrated at a dam, making them easy prey. Unfortunately, those salmonids were endangered species. A recent study [1] showed that knowledge of the network structure could have helped wildlife managers to detect that at first it was only a few successful individuals who “recruited” the others, and that the selective removal of these information spreaders could have contained the problem. In this case social network analysis could therefore have assisted in protecting the endangered salmonids while culling fewer sea lions.

Snijders also suggests a possible example for how animal social network analysis could be used in conservation work in Europe: “In cases of recently reintroduced group living animals, such as the European bison, social network analyses could give insights into how a population’s long-term persistence might vary with particular behavioural processes within the group. But also into how group and individual movements might be effectively manipulated to avoid human-wildlife conflicts such as entering restricted areas like farm land.”

Perspectives for implementation

In a field in which funds and time are limited, any newly suggested approach should have a distinct added value. Not every conservation challenge that is linked to a species’ social behaviour will require a social network approach to address it. The scientists also acknowledge that their proposal has to overcome another important hurdle first: before applying the knowledge of social relationships to management practices, it should become feasible and cost-effective to collect the required data in the first place. But with technological options becoming more common and affordable, an animal social network analysis approach could increasingly become an option.

There are several methods out there that have been successfully applied to map wildlife social networks, ranging from sampling individuals at fixed locations, to walking transects, to automatically spatially tracking the animals. Rapid advancements in technology, like proximity loggers and GPS tags, allow for ever smaller animal species to be tracked, while at the same time becoming more affordable. In addition, collaborations between research institutes and conservationists might provide opportunities for sharing the costs or the technology.
