Seed collection for plant propagation is an opportunity to reverse the trends of genetic degradation and species loss. Nurseries have a key role in conserving the gene pool of native plants. budworm choristoneura fumiferana: Topics by WorldWideScience… Dispersal can play an important role in the population dynamics of forest insects, but the role of long-distance immigration and emigration remains unclear due to the difficulty of quantifying dispersal distance and direction.

Beware those blackjacks | Farmer's Weekly The typical ‘blackjacks’ that attach themselves to passing animals and people radiate outwards as 1cm-long seeds crowned by two or three sharp awns. After fruiting, the plant dries out completely – even the roots become brittle. This is a mechanism to promote ‘zoochory’ – the dispersal of seeds through animal or human movement.
