1. Comparisons were made between castrated male Scottish Blackface sheep and red deer (Cervus elaphus) of voluntary forage intake (VFI), digestibility and the mean retention time (MRT) of a particulate-phase marker (103Ru-phenanthroline) in the alimentary tract, when a range of forages: dried-grass pellets, chopped dried grass, fresh-frozen Agrostis-Festuca spp. and heather (Calluna vulgaris, L...

A major benefit of supplementing non-ruminant feedstuffs with exogenous enzymes is presumed to be the degradation of plant cell-wall polysaccharides to metabolizable monosaccharide residues. In the present study, metabolic fates of (U-14C-labelled, 10 mM) glucose, galactose, mannose, xylose and arabinose were compared in the fowl, by measuring recoveries of 14C radioactivity in exhaled carbon d...

Antimicrobial activity of the acetone-, methanoland aqueousextracts of the lichens Lecanora atra, L. muralis, Parmelia saxatilis, P. sulcata and Parmeliopsis ambigua was explored in vitro against to six species of bacteria and 10 species of fungi, by the disc-diffusion method and determination of the minimal inhibitory concentration (MIC) by the Broth tube Dilution method. The aqueous extracts ...

The occurrence of Festuca trichophylla subsp. trichophylla in the flora of Croatia is confirmed. In June 1999 a small population was found on the edge of ^epi} polje, near the village of [u{njevica (Istria) growing on a relatively moist calcareous meadow belonging to the order Scorzoneretalia. The soil is weakly basiphillous with high amount of CaCO3. According to the present state of knowledge...

Insect herbivores can shift the composition of a plant community, but the mechanism underlying such shifts remains largely unexplored. A possibility is that insects alter the competitive symmetry between plant species. The effect of herbivory on competition likely depends on whether the plants are subjected to aboveground or belowground herbivory or both, and also depends on soil nitrogen level...

The introduction to [2] (and references contained therein) contains a comprehensive exposition of terminology and notations relative to this conjecture. Since we use the same terminology and notations, we do not reproduce them here. The introduction to [2] also contains an exposition of results on this conjecture obtained before the article [3] came out. In this article we prove the following t...

Weed infestation has been known to cause considerable reductions in crop yields, thereby hindering sustainable agriculture. Many plants in genus Euphorbia affect neighboring plants and other organisms by releasing chemicals into the environment. In view of the serious threat of weeds to agriculture, the allelochemicals of Euphorbia himalayensis and their allelopathic effects were investigated. ...
