We investigated rhodoliths (coralline red algae) from a subtropical ocality in the Gulf of California (Lithotharnniurn crassiusculurn) and a subarctic locality in Newfoundland (Lithotharnniurn glaciale) for their potential as paleoenvironmental rchives using microanalytical geochemical techniques tomeasure variations in ;5•80, Mg, and Ca. Rhodoliths are potentially well suited as recorders of s...

Rising atmospheric CO2 concentrations could cause a calcium carbonate subsaturation of Arctic surface waters in the next 20 yr, making these waters corrosive for calcareous organisms. It is presently unknown what effects this will have on Arctic calcifying organisms and the ecosystems of which they are integral components. So far, acidification effects on crustose coralline red algae (CCA) have...

In this study we present a comparative quantification of CaCO3 production rates by rhodolith-forming coralline red algal communities situated in high polar latitudes and assess which environmental parameters control these production rates. The present rhodoliths act as ecosystem engineers, and their carbonate skeletons provide an important ecological niche to a variety of benthic organisms. The...

The ability of benthic macrofauna to disperse and colonize new habitats throughout their life may contribute substantially to small-scale patchiness in abundances in different habitats. Microgastropods in coralline turf on rocky shores in Australia are very patchy in abundance at different spatio-temporal scales. They therefore represent an ideal assemblage for testing hypotheses about processe...

The present study was conducted to investigate the effect of the diet containing Laurencia caspica (red algae) on blood parameters and digestive enzymes activity of goldfish after 90-day period. Goldfish (weight 6.10±0.1 gr) were divided to four experimental groups (30 individuals in each replication) including experimental treatment of the control group (without using red algae) and three trea...

Coralline algae are important components in a large variety of ecosystems. Among them, rhodoliths group free-living coralline red that cover extensive coastal areas, from tropical to polar regions. In contrast other ecosystem engineers, limited research efforts preclude our understanding their physiology, underlying mechanisms, drivers and potential differences related species under varying env...
