We describe a statistically significant correlation between two well-characterized responses to dioxin-like compounds in birds; induction of 7-ethoxyresorufin-O-deethylase (EROD) activity in cultured hepatocytes, and embryo mortality. Data were obtained from a review of the literature. EROD EC50 values for 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) and 6 polychlorinated biphenyls (PCBs) were st...

Two species of the genus Baruscapillaria Moravec, 1982 are known to parasitise the small intestine of the common cormorant, Phalacrocorax carbo (L.): Baruscapillaria carbonis (Dubinin et Dubinina, 1940) and B. rudolphii Moravec, Scholz et Nasincová, 1994.

Haemoglobin is the iron-containing oxygen-transport metalloprotein that is present in the red blood cells of all vertebrates. In recent decades, there has been substantial interest in attempting to understand the structural basis and functional diversity of avian haemoglobins. Towards this end, purification, crystallization, preliminary X-ray diffraction and molecular-replacement studies have b...

In his influential essay “The Translator as the Creator of Canon,” Jerzy Jarniewicz outlines characteristics what he identifies “but two most interesting species” translator, ambassador and legislator. Building off Jarniewicz’s framework (while also being indebted to Sasha Colby’s concept a “poetics excavation”), in this I propose hybrid offspring legislator—the excavator—through example Americ...
