investigations on the direct seeding of Sitka spruce (Picea sitchensis) on upland restock sites, and monitored native woodlands, such as willow (Salix spp.), oak (Quercus robur, Q. petraea), holly (Ilex aquifolium

To understand the role of leaf-level plasticity and variability in species invasiveness, foliar characteristics were studied in relation to seasonal average integrated quantum flux density (Qint) in the understorey evergreen species Rhododendron ponticum and Ilex aquifolium at two sites. A native relict population of R. ponticum was sampled in southern ...

European Holly (Ilex aquifolium L.) was used to study the impact of one short (28 day) ozone fumigation episode on leaf production, leaf loss and stomatal conductance (g(s)), in order to explore potential longer term effects over 3 growing seasons. Young I. aquifolium plants received an episode of either charcoal-filtered air or ...

We investigated the role of seed predation by rodents in the recruitment of the fleshy-fruited trees Taxus baccata, Ilex aquifolium and Crataegus monogyna in temperate secondary forests in NW Spain. We measured the densities of dispersed seeds, early emerged seedlings, established recruits and adults, at four sites over a period of 2 years. Seed predation ...

Shade tolerance, plastic phenotypic response to light and sensitivity to photoinhibition were studied in holly (Ilex aquifolium L.) seedlings transported from the field to a greenhouse and in adult trees in the field. All plants were growing in, or originated from, continental Mediterranean sites in central Spain. Seedlings tolerated moderate but not deep ...

In the years 2003 and 2004 we have observed an about 70 hectare large area in the D�sseltal, the eastern part of the Neandertal in North Rhine-Westphalia. There we collected on trees, bushes and herbs and found about 150 microfungi of which some are new for Germany or the entire world. E.g.: Pseudocercospora populigena N. ALE-AGHA, U. BRAUN & G.B. FEIGE on Populus berolinensis; Vialaea ...

Seed dispersal patterns were studied in a north-western Spain temperate forest community to assess the performances of alternative dispersal kernels during two years with ecologically contrasting scenarios; a non-mast year, and a mast year of the dominant canopy species, beech Fagus sylvatica. Dispersal kernels were fitted under a Bayesian modeling framework. Both simple and mixture kernels were ...

Forty-eight extracts from 16 common Belgian trees from the Walloon Region forest were evaluated for in vitro growth inhibitory activity against the human LoVo colon cancer, PC3 prostate cancer, and U373 glioblastoma cell lines. Our study was performed with the aim of selecting plant candidates in order to later isolate new anticancer compounds from an easily affordable tree material. Extracts from ...

Long chain (C 16 -C 18 ) hydroxy fatty acids are obtained among the nonlignin-derived reaction products from the CuO oxidation of a variety of geochemical samples. In order to investigate the origin of these acids, the CuO reaction products of isolated cuticles and whole leaves were investigated. The reaction products from the CuO oxidation of purified apple ( Malus pumila ) cuticle include ...

Habitat fragmentation increases seed dispersal limitation across the landscape and may also affect subsequent demographic stages such as seedling establishment. Thus, the development of adequate plans for forest restoration requires an understanding of mechanisms by which fragmentation hampers seed delivery to deforested areas and knowledge of how fragmentation affects the relationship between ...

The water permeability of the leaves of three deciduous plants (Acer campestre, Fagus sylvatica, Quercus petraea) and two evergreen plants (Hedera helix, Ilex aquifolium) was analysed in order to assess its role as a mechanism of drought resistance. Cuticular permeances were determined by measurement of the water loss through adaxial, astomatous leaf ...

Bark of ten woody species, known to be rejected as a food source by the pine weevil, Hylobius abietis, were sequentially extracted by a Soxhlet apparatus with pentane followed by methanol. Species were alder (Alnus glutinosa), aspen (Populus tremula), beech (Fagus sylvatica), guelder rose (Viburnum opulus), holly (Ilex aquifolium), horse chestnut (Aesculus ...

The uptake kinetics and storage of PCBs by isolated cuticles and cuticular waxes from Hedera helix, Prunus laurocerasus, and Ilex aquifolium were studied. Small chambers were used, allowing variation in plant uptake parameters to be studied by having the same air boundary layer in each chamber. During the 64 day study tri- and tetrachlorinated biphenyls ...

In several studies of oak decline in Europe, a semi-papillate homothallic Phytophthora taxon was consistently isolated, together with other Phytophthora species, from rhizosphere soil samples. It was also found associated with necrotic fine roots and stem necroses of Fagus sylvatica and Alnus glutinosa. Due to morphological and physiological similarities, the semi-papillate isolates were ...
