Blackbrush (Coleogyne ramosissima) is a spinescent shrub occurring in nearly monospecific stands in the southwestern United States. Winter browsing by domestic goats stimulates spring twig production by blackbrush plants. Current season's twigs produced by older branches growing on the outer edges of the plant canopy (terminal branches) contained 2.37 times more tannins than did older twigs. Within blackbrush plants, current season's twigs on terminal branches contained 1.34 times more tannins than did current season's twigs on sprouts and younger branches (basal branches). When analysed separately, current season's terminal twigs contained 1.47 times more tannins than did leaves, while current season's basal twigs...

plant defense,
Data on intraguild predation of arthropods on the tarweed Hemizonia congesta. Arthropod counts (predators, herbivores, etc) and counts of entrapped arthropod corpses on focal plants in an experiment manipulating arthropod carrion amount and plant damage. Quantifications of plant damage and reproduction are presented. A duplicate digital object identifier (DOI) (https://doi.org/10.5066/F7M044NW) was accidentally published for this resource. The correct DOI for referencing this product is https://doi.org/10.5066/P9PD6HUW.
A pollen addition experiment was conducted on the leaves of Croton setiger, a Californian forb. Pollen was added to leaves of randomly selected plants, and control plants had no pollen added. Over 2013 and 2014 the number of predatory and herbivorous insects were counted on each plant, and the number of damaged leaves and plant size were measured.

Data were collected from an experimental greenhouse study in which Lepidium draba plants were grown from root cuttings to create plants at different ontogenic stages. Plants were arranged in mixed-age and single-age stands and exposed to the Lepidopteran herbivore, diamondback moth caterpillars. The success (biomass gain and surivival) of herbivores, the amount of feeding, and the growth of plants were recorded as responses to ontogenic stage. In addition, glucosinolates (a group of secondary metabolites known to act as defenses against herbivores) were quantified on plants of differing ontogenic stage.
