Girls, Cats, and Problems With Peer Reviews

Last week saw International Day of Women and Girls in Science. It’s an important day, recognising the importance of a strong female presence in the scientific community, and how far all scientific disciplines have to go to achieve gender equality.

So naturally the journal Biological Conservations decided to release a paper entitled Where There Are Girls, There Are Cats*. It’s an ill-informed, ill-conceived paper that essentially blames women for free-ranging cat populations. It is insulting to women, and quite frankly insulting to any scientist who has had a paper rejected in the last year (yes, I’m bitter). It’s also kind of hilarious in all the wrong ways. As such, there was justifiable mockery and jaw-droppage on Twitter. Yet as with the recent #PruittGate debacle, most of the community has veered away from directly attacking the researchers. They’ve been focussing on the real problem here – in this case the peer review system.

Killing 2 Million Cats: When Broad Targets Aren’t Enough

Conservation or politics? Australia’s target to kill 2 million cats (2019) Doherty et al., Conservation Letters, https://doi.org/10.1111/conl.12633

The Crux

We’ve talked a lot lately about competition between causes on Ecology for the Masses. Often when extra attention is given to one cause over another equally valid cause, it’s a product of social trends coinciding at the right time, sudden events capturing the public interest (think the Notre Dame fire) or a particularly effective marketing campaign. But sometimes a cause or a conservation target can be used to deliberately distract the public from another cause, and it’s a potential example of this that we’re looking at today.

Australia has long had an issue with cats. They’ve decimated populations of native species, playing a large hand in the extinction of many species found nowhere else. So it makes sense that part of Australia’s first Threatened Species Strategy would be to minimise the impact of cat populations on local wildlife. The strategy included a target of 2 million cats being killed between 2015 and 2020. Whilst this might sound like a reasonable goal, this paper argues that the actual scientific evidence supporting the target is pretty weak, and goes into some alternatives and motives.

Whom to Blame – Cats or Rats?

Feral cats are responsible for the decline of many endemic species worldwide. But will removing them boost rat populations, causing more potential harm?

The Crux

For centuries, rats have been portrayed as carriers of diseases and death; whereas our feline friends, worshipped by the ancient Egyptians, will definitely make your YouTube video go viral (a quick Google search of “cat video” shows 1 310 000 000 results). Both have been introduced, either accidentally or deliberately, to islands where endemic species have evolved and adapted to an environment without these generalist predators. So how do you know if eradicating one of them will make things better for the native wildlife?

Before taking radical conservation actions, it may be a good idea to understand how feral cats (the apex predator), rats (the mesopredator) and their common prey are affecting each other. Namely, if you kill all the cats, will there be more rats to prey on seabirds? On the other hand, will killing all the rats really reduce the predation by cats on seabirds?
