Fish introductions are considered one of the most widespread anthropogenic threats to aquatic ecosystems. Their negative impact on native amphibian communities has received increasing attention in recent years. We investigated the relationship between the introduced fish, emergent vegetation cover and native amphibians in man-made ponds generated by(More)
Traditional haymaking has created exceptionally high levels of plant species diversity in semi-natural grasslands of the Carpathian Mountains (Romania), the maintenance of which is jeopardized by recent abandonment and subsequent vegetation succession. We tested the hypothesis that the different life history strategies of dominant grasses cause different(More)
High biocultural diversity is often found in landscapes where farming practices have preserved diverse habitats and many ‘traditional’ cultural features. We assessed what impacts conservation and agri-environmental regulations had and have on the maintenance of some elements in traditional hay meadow management in two such cultural landscapes(More)
We modelled the effect of habitat heterogeneity on the abundance of the submediterranean Saponaria bellidifolia, a red list species in Romania. The study was designed at two scales: 100 and 0.5 m2. At larger scale, generalized additive models and canonical correspondence analysis were used to model the density of ramets, whereas at microscale, binomial(More)
"Left to itself, under the influence of chance, matter tends to group itself into as large molecules as possible. And experientially, life stands as the natural and normal continuation of this "moleculization" process. In the same conditions, and once it has emerged from the inorganic, life continues naturally, and in a combined twofold movement, to become(More)
