The use of cotyledon proteins to assess the genetic diversity in sweet holm oak
Journal of Forest Science, 2009 Sweet holm oak (Quercus ilex ssp. ballota Desf. Samp.) is an important broad-leaved tree spread in the Mediterranean basin. In Spain, few studies on the genetic variability of this species have been displayed.

The effect of temperature and humidity on the germination of holm oak and cork oak acorns
Forest Systems, 1992 Trials have been carried out with Holm oak and Cork oak acorns, in the same edafoclimatic conditions in land in Extremadura, in order to establish germination losses by growth temperatures and loss of humidity. The results show that temperature does not affect germination until it rises above 55º C, therefore it does not have a negative effect ...

Invasive goldfish trigger a regime shift in experimental lake ecosystems of varying trophic state
Journal of Animal Ecology, EarlyView.The pet trade distributes exotic animals around the globe that enrich human lives. However, some pets become pests when released into the wild. This study provides experimental evidence that goldfish will negatively affect native freshwater organisms and ecosystems.

Comparative leaf decomposition within the holm oak complex [PDF]
European Journal of Soil Biology, 2000 The decomposition of holm oak leaves was compared using material embracing the genetical range of the holm oak complex. Collection sites were located in Morocco (Quercus rotundifolia), in the French Provence (Q. ilex), and in the French Languedocian coast (Q. ilex x rotundifolia). Leaves (living and senescent) were taken directly on the tree and in the
