Patterns of Speciation Inferred from Mitochondrial DNA in North American Chthamalus (Cirripedia: Balanomorpha: Chthamaloidea)

Spatially heterogeneous, synchronous settlement of Chthamalus spp. larvae in northern Baja California

“…comm.). The northern limit of C. panamensis, another species of Chthamalus that could be present in the region, is located much further south, at 12°N on the Pacific coast of Mexico (see Table 1 in Wares 2001). Although most of the settlement probably corresponded to C. fissus, we submit that identifying settlers to the species level was not crucial for the purposes of our study, as larvae were used as a biological indicator of transport.…”

Stage-specific distribution of barnacle larvae in nearshore waters: potential for limited dispersal and high mortality rates

“…Chthamalus fissus is found from San Francisco to Baja California (Newman & Abbott 1980), and dominates the high to upper middle intertidal at La Jolla. Its latitudinal distribution, however, occasionally overlaps with that of C. dalli, a northern species found from Alaska to a southern limit that oscillates between Point Conception (Wares 2001) and San Diego (Newman & Abbott 1980). Although adult C. fissus and C. dalli can be identified by dissection and microscopic examination (Newman & Abbott 1980), their larvae are morphologically identical (Miller et al 1989).…”

Molecular phylogeny and phylogeography of free-living Bryozoa (Cupuladriidae) from both sides of the Isthmus of Panama

“…Comparisons in which less than 5% of 10,100 random reshufflings produced larger values are indicated with asterisks. K2P + C), 0.65%/my (two sets of geminate clades of grapsid crabs; Schubart et al, 1998;K2P), and 0.67%/ my (mangrove-associated chthamaloid barnacles; Wares, 2001; GTR + C). Although not obtained from transisthmian calibrations, similar rates have been observed for molluscs: 0.54-0.96 %/my (Mytilus; Rawson and Hilbish, 1995) and 0.57%/my (zebra mussels; Stepien et al, 1999;K2P).…”
