Phylogenetic relationships and the timing of evolutionary events are essential for understanding evolution on longer time scales. Cheilostome bryozoans a group ubiquitous, species-rich, marine colonial organisms with an excellent fossil record but lack phylogenetic inferred from molecular data. We present genome-skimmed data 395 cheilostomes combine these 315 published sequences to infer key among c. 500 cheilostome species. find that named genera species phylogenetically coherent, rendering...
We present a novel approach to investigating sibling relationships and reconstructing parental genotypes from progeny array. The Bayesian method we have employed is flexible may be applicable variety of situations in addition the one presented here. While mutation rates breeding population allele frequencies can taken into account, model requires relatively few loci makes assumptions. Paternity 270 veined squid (Loligo forbesi) hatchlings three egg strings collected location was assigned...
Summary We estimated fusion frequency with respect to coancestry in the bryozoan Celleporella hyalina , whose briefly planktonic sexually produced larvae settle on algal substrata and proceed form encrusting colonies by iterative budding. Frequency of between paired growing an artificial substratum was positively correlated coefficient relatedness, allorecognition ability increasing during early stages colonial growth after larval settlement. Parents repressed F 1 progeny which they had...
Prolific polyembryony is reported in few major taxa, but its occurrence has generated theoretical debate on potential conflict between sexual and asexual reproduction. It is, therefore, important to genetically confirm a widely cited inference, based microscopy, that characterizes marine bryozoans of the order Cyclostomata. Microsatellite genotyping brooded embryos maternal colonies conclusively demonstrated polyembryony, while genetic variation among broods within indicated outcrossing via...

Molecular and morphological evidence indicates that the widespread North Pacific species Diaulula sandiegensis is a complex of two pseudocryptic species. One ranges from Sea Japan to northern California, whereas other found California Baja California. The name applies southern odonoghuei Steinberg, 1963 species; neotype designated for latter. have consistent differences in colour pattern were overlooked previous studies.

Summary In a double‐blind study the therapeutic effect of 4% disodium cromoglycate (DSCG) nasal solution was evaluated in thirty‐nine patients with acute symptoms ragweed hay fever. Patients were randomly assigned to DSCG or placebo group as they presented allergic rhinitis. Overall, not more effective than controlling rhinitis decreasing need for concomitant antihistamines corticosteroids. Among highest pretreatment serum ragweed‐specific IgE (RW IgE) levels, drug‐treated had some reduction...
Abstract Cyclostomata bryozoa are thought to reproduce via polyembryony, a clonal replication of fertilized egg. To test this hypothesis and assess the impact their reproductive strategy on structure populations, we isolated microsatellite markers in Crisia denticulata (Cyclostomata, Stenolemata), using an initial enrichment step with random amplified polymorphic DNA (RAPD) primers. A total nine microsatellites, one tetra‐ eight dinucleotides repeats were isolated; seven found be sample 30...
Seven species of the cheilostome bryozoan genus Microporella were identified across 15 rocky intertidal sites spanning 940 km California coast, from Mill Creek in Montereyan Pacific Transition Region north to Point Saint George Mendocinian Region. Colonies found encrusting boulders and mollusc shells. Among these species, three are new science, namely dentata Chowdhury & Di Martino sp. nov., M. pauciperforata nov. rota Three other californica, setiformis, umbonata have previously been...
