🐺 Wolves and other large carnivore species are making a comeback in Europe.
Yet current conservation policies are still geared toward protecting species on the brink of extinction. This no longer reflects reality, argue researchers in a new commentary. www.stockholmresilience.org/5.1a496cd119...

Great paper! I really enjoyed it.

Hot from the @consletters.bsky.social press: "Now What? The Conundrum of Successful Recovery of Wolves and Other Species for European Conservation", where Erica Von Essen and I discuss future trajectories of species recovery and management in Europe.

Fundraising insight: highlight your global impact. Results suggest non-use values (not local reciprocity) drive giving, especially in internationally connected cities

Key results:
Probability of donating rises with scale: Local ~74% → UK ~80% → Global ~84% (difference significant).
Donation amounts given were similar across scales (avg ≈ £13). It’s the likelihood to give that shifts with scale, not how much.

We tested this with a revised dictator game + real payments: 600 London residents could give part of a potential £50 prize to charities working locally, nationally, or globally. Donation amounts were similar across scales.

New paper: Londoners are more likely to donate to national & global environmental causes than local. Our findings suggest environmental giving isn’t as parochial as human-directed altruism #EnvEcon #Climate #Philanthropy

🌾📉 New research published in @natureecoevo.bsky.social shows that intensifying existing farmland can sometimes harm local biodiversity more than expanding agricultural land.

The intensification of existing farmland can sometimes be more harmful to local #biodiversity than expanding the area covered by agricultural land, finds a new study led by Dr @silviaceausu.bsky.social with Prof @tnewbold31.bsky.social @uclcber.bsky.social @ucllifesciences.bsky.social #LandUse

Hi Maksym, thank you for replying! The very sharp transitions are due to how we define tropical and non-tropical areas - based on latitude. In reality, the transitions would be more gradual but the effects of yield increases are strongly differentiated for tropical and non-tropical areas.

No one-size-fits-all. Depending on landscape and crop, either expansion or intensification can better safeguard species richness, abundance, or community uniqueness.

In the tropics, raising yields can favour wide-ranging, generalist species—especially in areas with a higher percentage of natural vegetation—echoing past shifts seen in temperate zones.

Boosting yields isn’t a free lunch either! Closing yield gaps is associated with a median species loss of 9% and median abundance loss of 11%. Additionally, almost 40% of global agricultural landscapes, predominantly in the tropics, are likely to lose community uniqueness.

Agricultural conversion hits biodiversity hard: -11 % species loss in primary vegetation in modified landscapes; -25 % / −40 % in cropland within natural/modified landscapes. Land conversion also reduces abundance and community uniqueness,with impacts depending on landscape type
