Mixing regimes in tropical high‐mountain Andean lakes

Limnology and Oceanography, Volume 70, Issue 10, Page 2872-2892, October 2025.
Abstract Lowland tropical lakes deeper than 15 m are typically warm monomictic, but whether the regime may switch to polymixis at high elevations remains uncertain. Using a year‐long high‐frequency dataset from thermistor chains from 10 deep lakes and occasional temperature profiles from 202 lakes in Ecuador's Cajas Massif, this study examines the ...

Microbial drivers of root plasticity

New Phytologist, Volume 248, Issue 1, Page 52-67, October 2025.
Summary Soils are highly heterogeneous and dynamic systems, experiencing a constant flow of plant root exudates and moisture fluctuations that affect nutrient distribution, soil physicochemical properties, and microbial metabolisms. Plant roots adjust their development within the soil matrix (growth, branching, root angle, and anatomical features) by ...
