Notes on marine algae in the International Biosphere Reserve Seaflower, Caribbean Colombian I: new records of macroalgal epiphytes on the seagrass Thalassia testudinum

Range extension of Mesophyllum engelhartii (Foslie) W.H. Adey (Corallinales; Rhodophyta) to the Gulf of California: Morphology, anatomy and reproduction

Abstract We report for the first time a range extension of Mesophyllum engelhartii to the eastern Pacific Ocean. We focus on the Gulf of California, where samples were collected in Punta Perico at a depth of 30 m. Tetrasporangial and gametangial materials were found. The material clearly ha ... mehr

Substrate-dependent differences between the structures of epiphytic and epilithic diatom assemblages off the southwestern coast of the Gulf of California

Abstract To test the postulate that diatom assemblage structures differ between those growing on macroalgae and those on rocks used as substratum by macroalgae, we analyzed 29 samples of macroalgae and 15 of rocky substrata from localities in Bahía de La Paz, México. Assemblage structure wa ... mehr

Environmental requirements and habitat preferences of phytoplankton: chance and certainty in species selection

Abstract This paper is written in honour of the influential career of Professor T.J. Smayda. It celebrates the brief, but productive, period in which we collaborated on the formulation of the principles and mechanisms of community assembly in plankton. The topics considered then provide the ... mehr
