The One

A new athecate hydroid and its young medusa are described, the hydranths of which are commonly found embedded in colonies of the planktonic blue-green alga Trichodesmium thiebautii Gomont in the tropical and subtropical Atlantic. The hydroid and its medusa, named Pelagiana trichodesmiae n.gen., n.sp., are placed tentatively in the family Pandeidae (order Anthomedusae/Athecatae) because of the structure of the medusa and the one circle of filiform tentacles on the hydroid. The medusa is known only from one specimen which was 0.3 mm wide and 0.4 mm high immediately after release. It is deep bell shaped with a stomach one-third of the subumbrella and two marginal tentacles with large triangular marginal bulbs.

Agmenellum Quadruplicatum

Agmenellum quadruplicatum is a unicellular, non-nitrogen-fixing, marine cyanobacterium (blue-green alga). The ultrastructure of this organism, when grown in the laboratory with all necessary nutrients, has been characterized thoroughly. In contrast, little is known of its ultrastructure in the specific nutrient-limiting conditions typical of its natural habitat. Iron is one of the nutrients likely to limit this organism in such natural environments. It is also of great importance metabolically, being required for both photosynthesis and assimilation of nitrate. The purpose of this study was to assess the effects (if any) of iron limitation on the ultrastructure of A. quadruplicatum. It was part of a broader endeavor to elucidate the ultrastructure of cyanobacteria in natural systemsActively growing cells were placed in a growth medium containing 1% of its usual iron. The cultures were then sampled periodically for 10 days and prepared for thin sectioning TEM to assess the effects of iron limitation.
