Sandpipers Select Red Brine Shrimps Rich in Both Carotenoids and Parasites
Trophically transmitted parasites often manipulate the behaviour of their intermediate host, which is assumed to increase the vulnerability to predation by the final host (for a review, see Moore 2002). However, the adaptive value of behavioural changes associated with infections is difficult to demonstrate. Increased predation by the final host is the main criterion supporting adaptive manipul...
متن کاملWhen Parasites Are Good for Health: Cestode Parasitism Increases Resistance to Arsenic in Brine Shrimps.
Parasites and pollutants can both affect any living organism, and their interactions can be very important. To date, repeated studies have found that parasites and heavy metals or metalloids both have important negative effects on the health of animals, often in a synergistic manner. Here, we show for the first time that parasites can increase host resistance to metalloid arsenic, focusing on a...
متن کاملAerobic methanotrophic communities at the Red Sea brine-seawater interface
The central rift of the Red Sea contains 25 brine pools with different physicochemical conditions, dictating the diversity and abundance of the microbial community. Three of these pools, the Atlantis II, Kebrit and Discovery Deeps, are uniquely characterized by a high concentration of hydrocarbons. The brine-seawater interface, described as an anoxic-oxic (brine-seawater) boundary, is character...
متن کاملAvian cestodes affect the behaviour of their intermediate host Artemia parthenogenetica: an experimental study.
The brine shrimp Artemia parthenogenetica (Crustacea, Branchiopoda) is intermediate host for several cestode species whose final hosts are waterbirds. Previous field studies have shown that brine shrimps infected with cestodes have a bright red colour and are spatially segregated in the water column. However, the ethological mechanisms explaining such field observations are unknown. Changes in ...
متن کاملIsolation and characterization of a heavy metal-resistant, thermophilic esterase from a Red Sea brine pool.
The Red Sea Atlantis II brine pool is an extreme environment that displays multiple harsh conditions such as high temperature, high salinity and high concentrations of multiple, toxic heavy metals. The survival of microbes in such an environment by utilizing resistant enzymes makes them an excellent source of extremophilic enzymes. We constructed a fosmid metagenomic library using DNA isolated ...
