background: contagion of aquatic ecosystems to heavy metals especially mercury (hg) has risen concerns about healthiness of marine organisms. organic mercury compounds are highly toxic for animals, and its detection in various samples is frequently needed. in present study we have described a new method for measurement of organic mercury and total mercury concentration in great cormorants (phal...

The asymmetric unit of the title compound, [Co(NCS)2(C6H6NS)4]·CH3OH, consists of one cobalt(II) cation, two thio-cyanate anions, four pyridine-4-carbo-thio-amide ligands and one methanol mol-ecule that are located in general positions. The CoII cations are coordinated by two terminal N-bonding thio-cyanate anions and four N-bonding pyridine-4-carbo-thio-amide ligands, resulting in discrete and...

Dioxins including 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) induce various toxic effects through the aryl hydrocarbon receptor (AhR) signaling pathway. Here, we investigated the structural and functional characteristics and molecular evolution of multiple AhRs in black-footed albatross (Phoebastria nigripes) and common cormorant (Phalacrocorax carbo). We report the complementary DNA sequences ...

BACKGROUND Great cormorants (Phalacrocorax carbo L.) show the highest known foraging yield for a marine predator and they are often perceived to be in conflict with human economic interests. They are generally regarded as visually-guided, pursuit-dive foragers, so it would be expected that cormorants have excellent vision much like aerial predators, such as hawks which detect and pursue prey fr...
