Roles of transport and mixing processes in kelp forest ecology.
Fluid-dynamic transport and mixing processes affect birth, death, immigration and emigration rates in kelp forests, and can modulate broader community interactions. In the most highly studied canopy-forming kelp, Macrocystis pyrifera (the giant kelp), models of hydrodynamic and oceanographic phenomena influencing spore movement provide bounds on reproduction, quantify patterns of local and regi...
متن کاملHistorical ecology and the conservation of large, hermaphroditic fishes in Pacific Coast kelp forest ecosystems
The intensive commercial exploitation of California sheephead (Semicossyphus pulcher) has become a complex, multimillion-dollar industry. The fishery is of concern because of high harvest levels and potential indirect impacts of sheephead removals on the structure and function of kelp forest ecosystems. California sheephead are protogynous hermaphrodites that, as predators of sea urchins and ot...
متن کاملPopulation ecology of the invasive kelp Undaria pinnatifida in California: environmental and biological controls on demography
We combined field monitoring and laboratory experiments to examine the population ecology of both the microscopic and macroscopic stages of a new invasion of Undaria pinnatifida in California. Over the course of 1 yr, we observed 2 distinct recruitment pulses of individuals in the Santa Barbara harbor; the appearance of these pulses was strongly correlated with a 4°C drop in ocean temperature a...
متن کاملBehavioral ecology of young-of-the-year kelp rockfish, Sebastes atrovirens Jordan and Gilbert (Pisces: Scorpaenidae).
Young-of-the-year (YOY) kelp rockfish, Sebastes atrovirens, recruit initially to the canopy of the giant kelp, Macrocystis pyrifera (L.), along the coast of central California. During the summer of 1991, I observed major fluctuations in YOY kelp rockfish abundance in the canopy before the onset of a vertical migration downward to the Macrocystis holdfasts. Within the Macrocystis canopy, YOY kel...
متن کاملKelp surprise
Coral reefs are considered one of the most important tropical marine habitats. They are hotspots of biodiversity and productivity, so their vulnerability to environmental change has prompted efforts around the world to help manage and conserve threatened reefs. But, according to new work, another tropical environment also provides crucial support to organisms and has been somewhat overlooked be...
