Vegetación arbórea de selvas bajas caducifolias en suelos litosoles y regosoles eutricos degradados

open access: yesTerra Latinoamericana, 2020
En México, las selvas bajas caducifolias (SBC) son perturbadas por actividades agrícolas. Su regeneración origina el restablecimiento de vegetación arbórea secundaria que, con menor cobertura vegetal y arraigo, produce suelos termófilos e hidrófobos ...

Radial oxygen loss, rhizospheric methane oxidation and methane emissions from rice roots

open access: yesNew Phytologist, Volume 252, Issue 3, Page 1035-1049, November 2026.
Longitudinal variation in rice (Oryza sativa) root traits affecting the bidirectional diffusion of O2 and CH4. Summary Methane (CH4) produced in flooded paddy soils is emitted by passive diffusion, by ebullition and by diffusion through the rice (Oryza sativa) plant.

HORIZONTAL MERGERS FOR BUYER POWER [PDF]

open access: yes
Salant et al. (1983) showed in a Cournot setting that horizontal mergers are unprofitable because outsiders react by increasing their output. We show that this negative effect may be compensated by the positive effect that horizontal mergers have on the ...

FvGI–FvCO–FvFT1 pathway activates FvTFL1 in long days to repress flowering in woodland strawberry (Fragaria vesca)

open access: yesNew Phytologist, Volume 252, Issue 3, Page 1269-1282, November 2026.
Natural variation of flowering time correlates with FvFT1 and FvTFL1 expression in European Fragaria vesca accessions. Summary Photoperiod is a stable seasonal signal. Although photoperiodic flowering is well understood in short‐day (SD) and long‐day (LD) annual plants, the regulatory mechanisms in perennials remain elusive.
