Estimating divergence times from molecular data on phylogenetic and population genetic timescales. (1996). (1985). biodiversity loss than terrestrial ones, due to marine species' high dispersal Do urban structures influence local abundances and diversity of subtldal eplblota? (2005). (2008). Field experiments and observations in the Gulf of California suggested that the small, solid-walled species, Chthamalus anisopoma, competitively exlcudes the larger, tubiferous Tetraclita stalactifera confinis on the lower part of the shore. In: Advances. The old, inferior type had an elevated rate of extinction matched by an increased speciation rate of the superior type. In: Genetics and evolution of aquatic organisms. The balanoids have an advanced feeding mechanism, but the most important adaptive breakthrough leading to their competitive success was probably the origin of a tubiferous wall structure, which affords rapid skeletal growth for the efficient monopolization of free space and for the destruction of chthama- loids. Population and evolutionary genetics: a primer. Marine biodiverslty of the Mediterranean Sea: situation, problems and prospects for future research. Our case that the balanoids have competitively displaced the more primitive chthamaloids is based on several facts: (1) the Chthamaloidea have dwindled during the Cenozoic Era, so that most have relict or refugial distributions, whereas the Balanoidea have undergone a remarkable adaptive radiation; (2) balanoid species are known to defeat chthamaloid species in competition for space; (3) the competitive success of the balanoids can be attributed to an inherent biological feature—a tubiferous skeleton, which fosters rapid growth; (4) the peak diversity of living balanoids coincides precisely with the bathymetric gap in the chthamaloids’ distribution. Progression and dispersal of an introduced alga: Codium fragile ssp. Barnacle growth (or barnacle age) is dependent on the availability of food and the delivery rate of food , , , . The Bubbles of Pearl vs Sea Grapes vs Acorn Barnacle. Nei. (1990). (1991). Press question mark to learn the rest of the keyboard shortcuts. Other sea stars also use this species as prey, and dog whelks can drill into the shells. (2001). (1992). Landscape location affects genetic variation of Canada lynx (Lynx canadensis). test the hypothesis that marginal and peripheral populations tend to be less The subfamily Turrinae, INFLUENCE OF INTERSPECIFIC COMPETITION AND OTHER FACTORS ON DISTRIBUTION OF BARNACLE CHTHAMALUS STELLATUS, Structure and evolution of Antillean Cretaceous rudist frameworks. In this context the genetic pattern of the European barnacle Chthamalus (1990). Barnacles preference is to colonize PLS and the external parts of the shoes. Sea grapes wiggle back and forth a bit more. (1987). (1994). One hypothesis is that present distributions and patterns of evolutionary diversification and decline among acorn barnacles reflect the competitive exclusion and replacement of solid-walled forms by those with tubiferous skeletal structure. an integrated software package for population genetics data analysis. A phylogenetic study of chthamaloids (Cirripedia; Thoracica; Chthamaloidae) based on 16S rDNA and COl sequence analysis. The range of larval dispersal estimated for barnacles (Strathmann, (1984).

Another specialized group, the Trigoniacea, expanded dramatically in the Mesozoic through the evolution of somewhat unusual adaptations for efficient burrowing (Stanley, in preparation).
