Gymnoxanthella radiolariae gen. et sp. nov. (Dinophyceae), a dinoflagellate symbiont from solitary polycystine radiolarians
TLDR
The results suggest that at least two dinoflagellate symbiont species, peridinioid Zooxanthella nutricula and gymnod inioid G. radiolariae, exist in radiolarians, and that they may have been mixed and reported as “Z.nutricula” since the 19th century. Expand
Molecular delineation of species in the coral holobiont.
TLDR
An integrative approach to the delineation of species using both molecular genetics in combination with phenetic characters is advocated and an a priori set of criteria be developed for each taxonomic group as no one species concept or accompanying set of guidelines is appropriate for delineating all members of the coral holobiont.

Endosymbiotic bacteria associated with the intracellular green algae ofHydra viridis
TLDR
The presence of large numbers of bacteria in gastrodermal cells of three stains of freshwater green hydras has implications for interpretations of metabolic exchange between host and algal symbionts and for extrapolation of metabolic data from strain to strain of H. viridis. Expand
Relationship between sediment characteristics and size of the acoel turbellarian Convoluta roscoffensis graff
Samples of the acoel turbellarian Convoluta roscoffensis and of sediment were taken from several beaches on the Channel Islands. A positive relationship between the mean length of the animals andExpand
Eat and run? The hunger/satiation hypothesis in vertical migration: history, evidence and consequences
  • S. Pearre
  • Biology, Medicine
  • Biological reviews of the Cambridge Philosophical Society
  • 2003
TLDR
This review examines evidence for individual vertical movements gathered from ‘tracers ‘, mainly gut contents, and reviews the evidence for the hypothesis that such movements are in fact driven by hunger and satiation. Expand
SCRIPPSIELLA VELELLAE SP. NOV. (PERIDINIALES) AND GLOEOKINIUM VISCUM SP. NOV. (PHYTODINIALES), DINOFLAGELLATE SYMBIONTS OF TWO HYDROZOANS (CNIDIARIA) 1, 2
TLDR
These are the first descriptions of symbiotic dinoflagellate belonging to the orders Peridiniales and Phytodiniates, and the evidence currently points to seven genera in four orders of dinof lagellates having representatives that have entered a symbiotic mode of existence. Expand
NOMENCLATURE OF ENDOSYMBIOTIC DINOFLAGELLATES
TLDR
The nomenclature of symbiotic dinoflagellates harboured by animal hosts is reviewed with regard to its history and employment and it is proposed to reject Zooxanthella as a confusing name widely applied to taxa not including its type. Expand
Algal Symbiosis and Its Recognition in the Fossil Record
TLDR
In extreme cases of symbiosis, the reproductive systems of the partners are linked, so that continuation of the symbiosis is almost automatic; in these cases there are strong analogies with the meiotic sexual cycle. Expand
