Amiloride appeared to be weakly inductive to larvae of the hydroid
Hydractinia echinata: a 600 [micro]mol [l.
Studies on southwestern Atlantic intertidal hydroid
communities are rare, but include distributional inferences for the Brazilian tropical-subtropical coast (Rosso & Marques, 1997), and ecological assessments of seasonal richness, abundance, zonation and substrata for southern temperate waters (Genzano, 1994; Genzano & Rodriguez, 1998).
Doto form A is the most common Doto in the southern California bight and is commonly observed subtidally on campanularid hydroids
growing on kelp and other macroalgae.
Clearly, the hydroid
habitat offers a form of shelter and protection from abrasion and grazers.
Kongsberg's REMUS family of AUVs built by its subsidiary Hydroid
can also perform visual pipeline inspections and pipeline surveys when equipped with high-frequency sidescan sonar, a multi-beam and camera.
The Norwegian company entered the contract via its subsidiary Hydroid
The bottle brush hydroid
occurs in these chalk reefs.
In January 2002, various species of algae, sponge, hydroid
and tunicate colonies were scraped from the south jetty during an extremely low tide.
In the summer and fall, the shallow, well-lit portion of the jetty is dominated by brown seaweeds like Sargassum, Padina, and Dictyota, whereas the deeper portions are dominated by colonial invertebrates, including the scleractinian coral Oculina arbuscula, the upright bryozoan Bugula neritina, the hydroid
Eudendrium carneum, several species of tunicates, and a few sponges.
Katrina was searching the tidepools for a hydroid
that she had discovered several years ago: Samuraia tabuarasa.
Evolutionary genetics of allorecognition in the colonial hydroid
This dichotomy between the palatability of larval and adult extracts was not apparent for the hydroid
Eudendrium or the sponges Calyx or Ectyoplasia, for which extracts from both adults and larvae strongly deterred feeding (P [less than] 0.
