Seed predation due to the yucca moth symbiosis Seed predation due to the yucca moth symbiosis
All species of Yucca (Agavaceae) require the pollinator services of a species of moth in the genus Tegeticula (Lepidoptera: Incurvariidae). These moths oviposit in the ovary of the plants and the larvae are entirely dependent upon Yucca seeds for food. The extent and distribution of larval seed predation was examined in nine Yucca species in the southwestern United States. The proportion...

Post-fire recovery of California coastal sage scrub Post-fire recovery of California coastal sage scrub
Postfire regeneration of the shrub and herb vegetation on eight coastal slopes of California coastal sage scrub was studied in the first two growing seasons after fire. All shrub species resprouted with the exception of the suffrutescent Lotus scoparius, though it is not known if this species was alive prior to the fire. It was estimated that 70% of the prefire shrub populations...

Crassulacean acid metabolism in submerged aquatic plants Crassulacean acid metabolism in submerged aquatic plants
CO2-fixation in the dark is known to occur in various organs of many plants. However, only in species possessing crassulacean acid metabolism (CAM) does dark CO2-fixation contribute substantially to the carbon economy of the plant. Until very recently CAM was known only from terrestrial species, largely drought adapted succulents. The discovery of CAM in the submerged aquatic fern ally...
