Alternative stable states: Evidence from natural ecosystems and implications for ecological restoration

open access: yesEcological Solutions and Evidence, Volume 7, Issue 2, April/June 2026.
Ecosystems can occupy alternative stable states, maintained by positive feedbacks and critical thresholds. Recovery is often nonlinear, making simple driver reversal insufficient. Effective restoration should target critical thresholds, disrupt degradation‐reinforcing feedbacks and strengthen recovery‐promoting feedbacks.

Response of Tipping Elements to Different Strategies of Stratospheric Aerosol Injection

open access: yesEarth's Future
Stratospheric aerosol injection (SAI) has been proposed as a complementary option to mitigate anthropogenic climate change risks. Using Community Earth System Model ensemble simulations, we assess the response of climate metrics relevant to a set of ...

Rarity of monodominance in hyperdiverse Amazonian forests. [PDF]

open access: yes, 2019
Tropical forests are known for their high diversity. Yet, forest patches do occur in the tropics where a single tree species is dominant. Such "monodominant" forests are known from all of the main tropical regions. For Amazonia, we sampled the occurrence

Deconstructing the moral circle: Obligations as the driver of moral expansion

open access: yesBritish Journal of Social Psychology, Volume 65, Issue 2, April 2026.
Abstract Who do we believe deserves rights, and when do we feel personally obligated to protect them? Expanding the moral circle has been seen as a hallmark of moral progress, yet existing research has rarely examined how different kinds of moral judgements, recognizing rights versus endorsing obligations, shape this process.

Golden Gate Bridge, as Always? Eliciting Prototypical Places From Autoregressive Large Language Models via Category Production

open access: yesTransactions in GIS, Volume 30, Issue 2, April 2026.
ABSTRACT Among the various theories of categorization, Eleanor Rosch's prototype theory stands out as both influential and contested. In contrast to the classical theory of concepts, prototype theory posits that humans conceptualize the world using category structures where exemplars vary in their degree of membership.

Passive Gauze‐Based eDNA Sampler Proves Efficient and Cost‐Effective in the Marine Environment

open access: yesEnvironmental DNA, Volume 8, Issue 2, March/April 2026.
Here, we present the first empirical comparison of the metaprobe 2.0, a low‐cost, passive eDNA sampler, against an industry standard Sterivex filtration method using dip‐collected 1‐L water samples (“water bottles”). Across 14 joint deployments, we assessed detection and quantification of eDNA of two elasmobranch and two teleost species. While Sterivex
