The case of cats and conservation

Tanja and I explored another conservation conflict on our Medium blog.

When a potential response to an urgent situation is either unlikely to work at all or unlikely to address the bulk of the problem, under what conditions should we try it anyway?

In this exploration, we wanted to share perspectives on the controversial case of cats in Australia, also by some called the ‘war against cats’. In 2015, the Australian Government launched the threatened species strategy to kill 2 Mio cats in Australia by 2020 with the aim to protect endemic wildlife. Four years after the strategy was launched, Australian researchers in Conservation Letters questioned the motives (conservation or politically driven) and the science behind the decision.

Just how much of a sensitive topic this particular case study is, we noticed by how difficult it was for us to find contributors. Luckily we found two experts from Moral Philosophy that shared their insight with us:

Carlos Gray Santana is an Assistant Professor in Philosophy at the University of Utah. Dr Santana’s uses ethics to shed light on complicated issues such as the environment and human cognition. William S. Lynn is a Research Scientist in the George Perkins Marsh Institute at Clark University. The focus of Bill’s work is the ethics and politics of animal protection and sustainability.

For optional guidance, we asked the experts the following questions:

  • Why is the matter of cats and wildlife so controversial?
  • Why do you think politicians focus on culling cats rather than on habitat loss (as suggested in Doherty et al. 2019) and could open discussions be fostered to move beyond culling?
  • How do you think the public would respond when culling of cats turns out not to be effective in halting endemic species decline?

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.
