Biological Control. 51:140-146
The expected outcome of weed control in natural systems is that the decline of a dominant weed will result in an increase in diversity of the plant community but this has seldom been tested. Here we evaluate the response of the plant community follow

Breeding populations of grassland birds are declining across North America. Alteration of wintering-ground habitat in Mexico may be a significant causal component in these declines, considering the rapid changes in land use occurring there. We invest

Invasive alien plants frequently possess greater seed banks than native species in disturbed areas, but native disturbance-adapted species may also possess large seed banks. We analyzed seed banks of ten sites with varying grazing histories in a shru

Bird composition of habitat fragments in urban areas is expected to be associated with adjacent landscape and with smaller-scale factors within fragments. This study investigated the bird assemblage of coastal oak (Quercus garryana) fragments in Brit

One-hundred and sixty-three seeds from 38 shrubs of antelope bitterbrush (Purshia tridentata) from four different sites were individually analyzed for N and Mg content. Seed nutrient content has previously been shown to affect seedling growth, compet

The flowers of the arctic poppy (Papaver radicatum L.) track the sun, and the petals of the flowers reflect light towards the ovary. This study investigated the importance of petals to reproductive success in this species. We measured light intensity

Two components of the floral display of Viburnum opulus L. were manipulated to determine their effect on fruit initiation and maturation. We altered the size of the floral display by planting individual shrubs in groups of 1, 5, or 10 in 1985 and in

Reproductive output in plants can be affected by a number of factors that can have lasting fitness consequences. Factors influencing seed weight in herbaceous plants have been thoroughly explored, but are relatively unknown in woody plants. This stud

Seedling and juvenile size, growth, and survivorship in Solidago flexicaulis L. were compared among three sites in southern Ontario in an attempt to evaluate environmental versus population effects on phenotype. In 1983, seedlings at the Eden Mills s
