The complete larval development of the crab Cyrtograpsus affinis (Brachyura, Varunidae) was obtained by culture in the laboratory. Five zoeal stages, the megalopa and the first crab are described and illustrated. Larval development from hatching to first

ABSTRACT Of the three types of cytoskeleton known in animals—actin, microtubules, and intermediate filaments—only actin and microtubules exist in plants. Both play important roles in cellular shaping, organelle movement, organization of the endomembrane system, and cell signaling.

Making Two out of One: Kinesin Motors Driving Plant Cell Division
ABSTRACT The Kinesin superfamily of microtubule dependent motors is present in all eukaryotes. Not all of the subfamilies are represented in all kingdoms, and the ones that are do not always show conserved functions. Tight control of the cytoskeleton is essential for proper progression and completion of mitosis and cytokinesis, and key functions are ...

Effects of different diets on the molt of Ucides cordatus (LINNAEUS, 1763) (Decapoda: Ocypodidae) [PDF]
Crustacean larvae of certain species are lecithotrophic completing their development without feeding. However, feeding seems to be essential to complete the entire molting process in larvae of Ucides cordatus (LINNAEUS, 1763).

Dungeness crab research program; Report for the year 1977 [PDF]
All 1977 year class larval stages, except fifth zoeae, occurred in the study area. California Cooperative Oceanic Fisheries Investigations (CalCOFI) plankton samples of February 1950, taken 67 and 111 miles off San Francisco, contained fifth stage ...

The aim of our study was to assess the combined impact of UVR (280–400 nm) and temperature on the first larval stage (Zoea I) of three crab species from the Patagonian coast: Cyrtograpsus altimanus, C. angulatus, and Leucippa pentagona. We determined the

The addition of Na2CO3 or K2CO3 to sewage sludge prior to combustion leads to the production of ashes containing phosphate in the form of buchwaldite‐like phases (Ca(Na/K)PO4). Compared to conventional sewage sludge mono‐ashes, such Na‐ or K‐ashes show greatly increased P‐solubilities and proved to be potent P‐fertiliser materials in greenhouse ...

Food habits and dietary variability of pelagic nekton off Oregon and Washington, 1979-1984 [PDF]
The food habits of 20 species of pelagic nekton were investigated from collections made with small-mesh purse seines from 1979-84 off Washington and Oregon. Four species (spiny dogfish, Squalus acanthias; soupfin shark, Galeorhinus zyopterus; blue shark,
