Endangered mutualisms: the conservation of plant-pollinator interactions

Article Abstract:

Pollination systems are increasingly under threat from anthropogenic sources. Threats include nonnative plants and animals, fragmented habitats, land use changes, and modern agricultural practices, especially use of pesticides and herbicides. The pollination crisis may be helped by cultivation of a diverse group of crop pollinators and by changes in habitat use. More ecological research into plant-pollinator interactions is needed. Pollination of flowering plants by animals is a critical ecosystem service of much value to humanity in monetary terms and in other ways and need for active conservation of pollination interactions is beginning to be appreciated.

Mechanisms of maintenance of species diversity

Article Abstract:

Two primary means of maintaining biodiversity within an ecosystem are considered, stabilizing processes and equalizing processes. Stabilizing mechanisms take the form of frequency-dependent predation and resource partitioning, while equalizing mechanisms decrease large inequalities in average fitness that might negate stabilizing mechanisms.

The evolution of predator-prey interactions: theory and evidence

Article Abstract:

The use of geographically structured populations is advanced as an additional theoretical tool to analyze predator-prey relationships and their individual evolutionary processes. Topics discussed include stability and equilibrium.
