Hi. Today in “One day, one paper”,restoration of oligotrophic peatlands via ditch filling and tree harvesting induces non-linear vegetation shifts.Sedges respond quickly; Sphagnum mosses recover more slowly. Similarity to undrained peatlands increases, highlighting the need for long-term monitoring🌎

Restoration induced long‐term vegetation change in oligotrophic peatlands

Here we show that restoration increases the resemblance to undrained peatlands, with little differences between the tree harvesting methods. We suggest that Sphagnum moss cover could be used in monit....

Good morning everyone. Today in "One day, one paper", in the Atlantic Forest, bird-excavated cavities are rarely reused. Why? Not scarcity, but low suitability. Multi-state models show they often shift from occupied to empty rather than being reused 🌎

Resource suitability drives low use of avian‐excavated tree cavities: A multi‐state occupancy dynamics approach

Birds that nest in tree cavities are sometimes dependent on a few cavity-excavating bird species to make nesting sites available. Such interdependency, however, does not always materialize because ex...

Great point! The study shows that when it comes to taking action, policy design is key. Public support increases if wealthy countries pay more, if nature (in its intrinsic value) is prioritized over the economy, and if financing schemes don’t rely on a general tax increase.
