Pimpinella saxifraga is maintained in road verges by mosaic management

Pimpinella Saxifraga Is Maintained in Road

17 Road verges have been proposed as refuges for vulnerable grassland species in the 18 modern, changing landscape, but little comparative knowledge exists on how 19 management regimes affect population dynamics of such species. We compared the 20 effects of various management regimes on population dynamics of Pimpinella saxifraga 21 in road verges and pastures, using elasticities and LTRE-anal...

The Compositions of the Essential Root Oils from Pimpinella saxifraga s.l. and Chemotaxonomic Implications

The essential root oils of the Pimpinella saxifraga subspecies eusaxifraga, alpestris and nigra were investigated by means of capillary GC and spectroscopic methods. A total of 48 components was identified. Characteristic constituents of all oils are pseudoisoeugenol derivatives, sesquiterpenoids and trinor-sesquiterpene hydrocarbons, but the qualitative and quantitative patterns of the individ...

Seed Spillage from Grain Trailers on Road Verges during Oilseed Rape Harvest: An Experimental Survey

CONTEXT Anthropogenic vectors enhance the natural dispersal capacity of plant seeds significantly in terms of quantity and distance. Human-mediated seed dispersal (i.e. anthropochory) greatly increases the dispersal of crop species across agroecosystems. In the case of oilseed rape (OSR), spillage of seeds from grain trailers during harvest has never been quantified. METHODS Our experimental ...

Unpaved road verges as hotspots of fleshy-fruited shrub recruitment and establishment

Neural integrity is maintained by dystrophin in C. elegans

The dystrophin protein complex (DPC), composed of dystrophin and associated proteins, is essential for maintaining muscle membrane integrity. The link between mutations in dystrophin and the devastating muscle failure of Duchenne's muscular dystrophy (DMD) has been well established. Less well appreciated are the accompanying cognitive impairment and neuropsychiatric disorders also presented in ...
