Surveys of Gene Families Using Polymerase Chain Reaction: PCR Selection and PCR Drift
with the potential to be phylogenetically informative (e.g., sequence variation, vari? ation within gene clusters, and number of gene clusters [Koop et al., 1989; Bartels et al., 1993; Cartwright et
Intertidal Bryozoa (Cheilostomata) of Ketchikan, Alaska
TLDR
The number of species per site was within the range of values previously observed in a more extensive study at Kodiak, Alaska, suggesting both similar intertidal species richness at the two localities, and that sampling of other interTidal sites at Ketchikan would detect additional species.
Neogene Cupuladriidae of Tropical America. II: Taxonomy of Recent Discoporella from Opposite Sides of the Isthmus of Panama
TLDR
Up to 30 morphological characters were used to discriminate and describe species of the genus Discoporella based on complete colony specimens collected from both coasts of the Isthmus of Panama, reflecting a similar pattern recently described for the genus Cupuladria from the same region.
Diversity and taxonomy of intertidal Bryozoa (Cheilostomata) at Akkeshi Bay, Hokkaido, Japan
TLDR
The overall species richness of intertidal cheilostomes was two‐thirds that documented intertidally in a comparable study at Kodiak, Alaska, a locality 15° higher in latitude, and the lower richness at Akkeshi to differences in the nearshore marine environment between the two localities is attributed.
NEOGENE CUPULADRIIDAE OF TROPICAL AMERICA. I: TAXONOMY OF RECENT CUPULADRIA FROM OPPOSITE SIDES OF THE ISTHMUS OF PANAMA
TLDR
Up to 28 morphological characters were used to discriminate and describe species of the genus Cupuladria based on entire colony specimens collected from both coasts of the Isthmus of Panama, agreeing well with previously described patterns from other cheilostome genera based on similar analyses.
Homeoboxes in cnidarians.
TLDR
The first homeoboxes from cnidarians, a phylum of diploblastic organisms thought to occupy a near-basal position in metazoan phylogeny, are reported here.
Epibionts of the Tanner Crab Chionoecetes Bairdi in the Region of Kodiak Island, Alaska
TLDR
Epibionts are likely to be of limited use as a management tool, because of difficulties in accurately assessing the age composition of commercial samples and the likelihood of temporal and geographic variation in recruitment of epibiont organisms, but are probably a significant factor in the population dynamics of C. bairdi and worthy of further investigation.
Over one-half billion years of head conservation? Expression of an ems class gene in Hydractinia symbiolongicarpus (Cnidaria: Hydrozoa).
TLDR
Findings establish that the association of ems-class genes with head structures preceded the evolution of bilateral symmetry.
Two Kinorhynch Species (Cyclorhagida, Echinoderidae, Echinoderes) Show Different Distribution Patterns Across Tsugaru Strait, Northern Japan
TLDR
Investigating the geographic population structures of two intertidal kinorhynch species in the vicinity of Tsugaru Strait between Honshu and Hokkaido Islands, Japan, to examine whether the distribution or connectivity of populations of either species has been constrained by the strait finds differences in these species' distributions and apparent connectivity.
