The phylogenetic position of hexaploid Elymus repens within the tribe Triticeae (Poaceae) was examined using cloned sequences from the low-copy nuclear genes encoding phosphoenolpyruvate carboxylase (pepC) and beta-amylase. A previous analysis of E. repens using data from the nuclear granule-bound starch synthase I (GBSSI) gene had yielded five phylogenetically distinct gene copies, two more th...

An experiment was performed to study the effect of feeding by the larvae of Tipula paludosa (Meig.) on the plant biomass of two contrasting plant species and on the soil microbial community, under controlled conditions. Agrostis capillaris (L.) (bentgrass) and Trifolium repens (L.) (white clover), were grown in pots, in monoculture and as mixtures, containing soil from an upland grassland site ...

Abundances and interactions among biological control insects and their effects on target invasive plants were monitored within the flower heads and roots of diffuse knapweed, Centaurea diffusa, and in spotted knapweed, Centaurea stoebe, along the Colorado Front Range. Flower weevils, (Larinus species) and root-feeders (Cyphocleonus achates and Sphenoptera jugoslavica) were released on knapweed ...
