The fine structure of pit plugs was examined in 63 species of red algae representing 34
families. The number of plug cap layers was found to be a taxonomically reliable character …

This paper presents results from the first comprehensive study of hexactinellid tissue
organization by electron microscopy. It is confirmed that the trabecular tissue of …

Acting as titans in global control of the biosphere and colonizing virtually all corners of the
earth, algae, extremely diverse and numerous oxygenic, photosynthetic organisms, can be …

Publisher Summary This chapter discusses the morphological and cytological aspects of
algal calcification. The deposition of calcium salts may occur either extra, inter, or …

Ultraviolet radiation (UVR) affects macroalgae in many important ways, including reduced
growth rate, reduction of primary productivity and changes in cell biology and ultrastructure …

The effects of ultraviolet radiation-B (UVBR) in apical segments of the red macroalgae
Gracilaria domingensis (Kützing) Sonder ex Dickie were examined in vitro. Over a period of …

The combined effects of ultraviolet radiation (UVR) and nutrients on the red macroalga
Gracilariopsis longissima were analyzed for 14 days in a 2× 2 factorial experiment design …

During the normal course of infection, nuclei are transferred via secondary pit connections
from the parasitic marine red alga Choreocolax to its red algal host Polysiphonia. These …

The fine structure of pit plugs in 90 species of red algae was examined, bringing the total
number of species in the continuing survey to 153. The organization of plug caps was …

Abstract The Gymnocodiaceae and fossil Udoteaceae (erect) are similar to each other both
in growth form and in vegetative structure. They differ in that the Gymnocodiaceae contain …
