NEW JOB with @RSPBScience in #ornithology to analyze citizen science data of common #birds in #Britain: buff.ly/vr8iphE

These two studies do not contradict each other but reinforce the desperate need to get strongly regulated and strictly enforced MPAs in place - not just boxes on a map with little effect

Steffen Oppel @steffopp.bsky.social · Jul 28

How is that possible? Quite simple - the second paper only looks at a small subset of strictly regulated MPAs. They have good enforcement, and may never had any fishing in the first place - so very little occurs there now

Steffen Oppel @steffopp.bsky.social · Jul 28

The second paper finds very little industrial fishing in the highly regulated and strictly protected MPAs: buff.ly/HYHfwwh

Steffen Oppel @steffopp.bsky.social · Jul 28

The first paper finds a lot of industrial fishing in all coastal MPAs, which is alarming because there does not seem to be much protection at all: buff.ly/S9IIg0t

NEW PAPERS in #conservation that seem to contradict each other about whether marine protected areas (MPAs) effectively reduce industrial fishing

NEW JOB in #ornithology and #conservation managing two major restoration projects for #islands important for #seabirds: buff.ly/yfl1Vo2

The mice were introduced by people, so this is a human-caused problem. Because mice have no natural predators on this island, the mouse population depletes it's food supply forcing mice to eventually explore alternative food sources like seabirds

NEW PAPER in #ornithology shows that #seabirds on Marion #island continue to be assaulted by invasive mice now killing adult #albatrosses: buff.ly/ITtVrwN

NEW PAPER collates #telemetry data of >100 marine vertebrate species including #seabirds and finds that protecting only 30% of the global ocean is not enough - because marine animals live everywhere: buff.ly/mYrtoAN
