Prebiotics, such as digestion-resistant fibers, influence the composition of gut microbiota, and can contribute to the improvement of host health. The red seaweed Chondrus crispus is rich in dietary fiber and oligosaccharides, however its prebiotic potential has not been stud...

Hydrochorous dispersal through agricultural channels plays a role in structuring plant communities across landscapes. To date, research on seed retention vegetated areas has mainly focused vegetation types with simple architecture (often cylinders), which consequently do not represent real features. Here, we test the hypothesis that cover estimated at water surface best explains floating open c...

Abstract Climatic niche shifts occur when species occupy different climates in the introduced range than their native range. are known to across a of taxa, however we do not currently understand whether climatic can consistently be predicted multiple ranges. Using three congeneric weed species, investigate one consistent other ranges where has been introduced. We compared conditions occupied by...

Alfalfa is one of the most important perennial fodder crops, and it also economical. provides first class that suitable for feeding all livestock, especially ruminants. Grass broadleaf weeds are a serious threat to quality viability alfalfa stands. Weeds can reduce nutritional value crop cause significant reductions in yield, as they compete aggressively water, nutrients, sunlight, space. In th...
