New Phytologist, Volume 248, Issue 2, Page 1002-1020, October 2025.Summary AP1/FUL‐clade transcription factors (TFs) are essential for the initiation and regulation of flowering and have clearly separated functions in Arabidopsis. However, how these functions have diverged across eudicots remains unclear. Here, we performed a detailed analysis to unravel the distinct and overlapping functions of the tomato AP1 ...

Thresholds for spring freeze: measuring risk to improve predictions in a warming world
New Phytologist, Volume 248, Issue 2, Page 563-575, October 2025.Summary Plant distribution and productivity are shaped by environmental stressors, particularly freezing events in extra‐tropical regions. In early spring, a progressive loss of cold hardiness with phenological development leaves emerging tissues vulnerable to freezing events.

Biología reproductiva de la uchuva
Acta Agronómica, 2008 Los objetivos del trabajo fueron determinar la época de maduración del polen y del estigma y establecer el tipo de polinización de la uchuva en condiciones de invernadero con cinco genotipos de uchuva.

Journal of Ecology, Volume 113, Issue 8, Page 2187-2198, August 2025.Individuals who engage in multiple mutualisms often have to pay indirect costs because of the interference of one mutualism on another. We found that protective ants had a low but variable impact on pollination, especially on the flower visitation by bees and when EFNs are close to inflorescences.

Spatiotemporal Dynamics of Non‐Ecological Speciation in Rubyspot Damselflies (Hetaerina spp.)
Molecular Ecology, Volume 34, Issue 12, June 2025.ABSTRACT Non‐ecological speciation is a common mode of speciation, which occurs when allopatric lineages diverge in the absence of pronounced ecological differences. Yet, relative to other speciation mechanisms, non‐ecological speciation remains understudied.
