New preprint: Don’t forget about your friends

Remember those friends you never saw anymore after they got hitched? Not in geese.

In our recently published preprint we show that barnacle geese keep hanging out with there favourite early-life social companions also after they pair up. Females show a break during the breeding season but display their social preferences again in the following winter. Males keep their prefered companions throughout the breeding and wintering season and these companionships were predicted by familiarity and genetic relatedness.

We also show that especially males were aggressive during the breeding season towards both males and females and this possibly hampered their female partners to hang out with their own ‘friends’ during breeding but not winter.

In summary, our study reveals the robustness of social bonds formed early in life, carrying over across pair formation, even after extended temporal disruptions. Our findings thus highlight how the early-life social environment can have life-long consequences on individuals’ social life, even in monogamous species.

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?

New publication: Repeatability of signalling traits in the avian dawn chorus

Our newest open access paper on repeatability of avian signalling (song)  traits just came online in the journal Frontiers in Zoology.

Repeatability, consistent individual differences, in signalling behaviour is interesting because it means that those receiving the signal (i.e. listening to the song) could reliably learn something about how the individual singer compares to other singers/competitors.

We repeatedly recorded the dawn song of great tit males throughout the breeding season and show that start time of dawn song and repertoire size are individually repeatable both before and during the egg-laying stage of the mate (when she is fertile). Surprisingly the time a male started singing appeared to be more repeatable (consistent) than repertoire size, despite that the start time was also influenced by variable overnight temperatures. Start time was also more repeatable before than during egg-laying and we suggest that this is related to the behaviour of the (assumingly) intended receivers of the song, the females.

For a subset of the singers, we also explored a potential link between the absolute song trait values, the repeatability of these values and personality. We did not find a link but follow-up studies with a larger sample size, and including additional song traits, will be needed to confirm the true absence of such a link.

New publication: Effectiveness of animal conditioning interventions

Our systematic map protocol, outlining the background and methods of our approach to map and review the effectiveness of animal conditioning interventions in reducing human-wildlife conflict, is now online.

SysMap_print

This map is part of a special initiative of a team of behavioural ecologists, who all committed to systematically map and/or review a topic in conservation behaviour. Read more about our plans and the protocols of the other team members here.

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.”

Please follow this link for more details.

Namib desert horses (Equus ferus caballus)

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!
