The underappreciated roles of fog and dew on vegetation and biocrusts

New Phytologist, Volume 251, Issue 1, Page 46-63, July 2026.
Summary Fog and dew represent minor components of ecosystem water budgets in most ecosystems. However, fog and dew can play an essential role in ecosystem dynamics and are particularly important for water‐limited systems. In addition to serving as direct water inputs, fog and dew can influence microclimate and water redistribution, thereby promoting ...

Greeffiella bellula n. sp. (Nematoda: Desmoscolecida): The First Desmoscolecid Nematode Species to Be Described From New Zealand

New Zealand Journal of Marine and Freshwater Research, Volume 60, Issue 2, June 2026.
The mostly marine nematode order Desmoscolecida is globally distributed with over 270 species known to date. Here, we describe Greeffiella bellula n. sp., the first desmoscolecid species to be described from New Zealand waters, from deep‐sea sediments. The new species is most similar to G. japonica, described from coastal sediments in the Sea of Japan,

Atmospheric dust is a global nutrient source for plants via foliar uptake

New Phytologist, Volume 250, Issue 5, Page 2867-2883, June 2026.
Summary Atmospheric mineral dust is a critical nutrient supplier to marine ecosystems, but its role in terrestrial plant nutrition remains underexplored due to the assumption that nutrients are acquired solely from soils via roots. Here, we demonstrate that plants directly acquire nutrients from dust through leaves, revealing an unrecognized ...
