Buffering role of the intertidal anemone Anthopleura aureoradiata in cercarial transmission from snails to crabs

Covering behavior in two intertidal anemones, Anthopleura elegantissima and Anthopleura xanthogrammica: Is it inducible in the lab?

Parasitism can influence the intertidal zonation of non-host organisms

Zonation of organisms in soft-bottom intertidal habitats is mainly a consequence of the tidal sorting of the substrate and how benthic organisms respond to it, with predation and competition also playing a role. Although parasites are ubiquitous in these habitats and known agents of community structure, their impact on zonation is rarely considered. Here, using observational and experimental da...

The intertidal distribution of two algal symbionts hosted by Anthopleura xanthogrammica (Brandt 1835).

This paper quantifies the spatial distribution of zooxanthellae (ZX) and zoochlorellae (ZC), two algal symbionts common to the temperate anemone, Anthopleura xanthogrammica, in relation to shore height. Anemones in tidepools and crevices had varying algal proportions: >0.90 ZC (green anemones), 0.10 to 0.90 ZX (mixed), and >0.90 ZX (brown). Brown anemones are primarily found in the high interti...

Diversity and distribution of True Crabs (Brachyura) from intertidal rocky shores of Qeshm Island, Persian Gulf

Rocky shores are one of the most important habitats of marine environment in coastal areas. This study was done in 2010-2011 to investigate the diversity of true crabs in intertidal rocky shores of Qeshm island. Samples were collected from intertidal zones during the low-tide at 5 stations. The specimens were fixed in 70% Etanol and transferred to laboratory for identification. Altogether, 15 c...

Parasites and global warming: net effects of temperature on an intertidal host–parasite system

Climate changes, particularly global warming, are likely to impact host–parasite interactions. However, our understanding of the effects of environmental factors on marine host–parasite systems is limited. We conducted a series of laboratory experiments on the effects of temperature on all transmission steps of the intertidal trematode Maritrema novaezealandensis from its first intermediate sna...
