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

Dinàmica orientacional i estructura local en liquids moleculars sobrerefredats
The aim of this thesis is to study, by means of molecular dynamics simulations, the behaviour of two molecular models at different temperatures, approaching the glass transition. One of them mimics methanol molecules, whereas the other differs from the former only in the ability of forming hydrogen bonds.

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.

Dung beetles suppressed cumulative methane flux from cattle dung by 85% and reduced total greenhouse gas emissions by 18%. Beetle activity accelerated initial CO2 release but did not alter total cumulative flux. N2O and NH3 fluxes were transient and not consistently driven by beetle presence.

Evidence for regulation of transpiration in nonstomatal plants: insights from bryophyte gametophytes
Kinetics of cell wall water vapor potential (Ψcw) and resistance of cell wall and plasmatic membrane to water flux in response to cytoplasmic water potential (Ψcyt) during dehydration. Ψcyt was calculated from the WC at any moment of the dehydration curve by using the relationship between −1/Ψw and WC of pressure volume curves and assuming Ψw = Ψcyt ...
