Life histories of Mediterranean pines
The life history of Spanish pines and their relation to fire as the main disturbance factor in their ecosystems was analysed. The primary ecological attributes studied were the canopy seed bank… Expand
Detection of hybrids in nature: application to oaks (Quercus suber and Q. ilex)
Powerful and accurate detection of first-generation (F1) hybrids and backcrosses in nature is needed to achieve a better understanding of the function and dynamics of introgression. To document the… Expand

- Environmental Science, Medicine
This study characterized and mapped the spatial variability patterns of seven topsoil heavy metals (Cr, Ni, Pb, Cu, Zn, Hg and Cd) within the Ebro river basin (9.3 million ha) by Multivariate… Expand
Genetic variation and migration pathways of maritime pine (Pinus pinaster Ait) in the Iberian peninsula
Abstract The genetic variability and migration pathways of Pinus pinaster after glaciation in the Iberian peninsula was studied by means of 18 loci from 12 natural populations of the species. The… Expand
Patterns of pollen dispersal in a small population of Pinus sylvestris L. revealed by total-exclusion paternity analysis
Patterns of pollen dispersal were investigated in a small, isolated, relict population of Pinus sylvestris L., consisting of 36 trees. A total-exclusion battery comprising four chloroplast and two… Expand
Effects of the interaction between drought and shade on water relations, gas exchange and morphological traits in cork oak (Quercus suber L.) seedlings
Abstract The combined effect of drought and light on different physiological and biochemical traits was assessed in cork oak (Quercus suber L.) seedlings grown under two levels of light availability… Expand
Increased selfing and correlated paternity in a small population of a predominantly outcrossing conifer, Pinus sylvestris
Outcrossing rate, the rates of ovule and seed abortion, and levels of correlated paternity were estimated in a small population of Pinus sylvestris, a predominantly outcrossing conifer, and were… Expand
Canopy seed banks in Mediterranean pines of south-eastern Spain: a comparison between Pinus halepensis Mill., P. pinaster Ait., P. nigra Arn. and P. pinea L.
Summary 1 Canopy seed banks were analysed in post-fire stands of Pinus halepensis, P. pinaster, P. nigra, and P. pinea. We determined age when flowering begins, age of first cone bearing,… Expand
Moonlight and shelter cause differential seed selection and removal by rodents
Various environmental factors may influence the foraging behaviour of seed dispersers which could ultimately affect the seed dispersal process. We examined whether moonlight levels and the presence… Expand
Leftovers in seed dispersal: ecological implications of partial seed consumption for oak regeneration
Summary 1. Successful seed dispersal by animals is assumed to occur when undamaged seeds arrive at a favourable microsite. Most seed removal and dispersal studies consider only two possible seed… Expand
