Hydrological Processes, Volume 40, Issue 5, May 2026.Isotopes data help to understand the GW‐SW connectivity, the recharge elevations, and evaporation in a volcanic lake basin. ABSTRACT Understanding groundwater (GW) to surface water (SW) connectivity (i.e., the exchange of water and solutes between aquifers and surface bodies) is increasingly important under changing climate conditions, where ...

Journal of Applied Ecology, Volume 63, Issue 5, May 2026.These case studies suggest that both seed‐based and seedling‐based approaches can restore pairwise species interactions to a similar extent. The seedling‐based method, although more expensive, provides immediate visual impact by directly introducing canopy‐forming species into the system.

Journal of Vegetation Science, Volume 37, Issue 3, May/June 2026.Spanish juniper woodlands are expanding across central Spain as farmland is abandoned. By combining 34 years of land‐cover data with high‐resolution photogrammetry and field measurements, we show that juniper growth depends on topography, solar exposure and competition with shrubs. High irradiance increases biomass in older stands but limits young ones,

Palaeontology, Volume 69, Issue 3, May/June 2026.Abstract Lauraceae are a tropical–subtropical angiosperm family that exhibit significant diversity and a rich fossil record, primarily of leaves found worldwide from the Cretaceous to the present. However, the taxonomic placement of many fossil leaves remains uncertain because of morphological convergence and limited variation in leaf characters among ...
