The common kestrel Falco tinnunculus Linnaeus, 1758, is a widespread raptor, native in Europe, Asia and Africa, and vagrant in the Americas. In the current work, 27 fecal samples were collected from common kestrels kept in the Lisbon Center for Wild Animal Recovery, located at Monsanto Forest Park, Lisbon, Portugal. Five (19%) of them were found to be passing an undescribed species of Caryospor...

A captive specimen of Meller's chameleon, Trioceros melleri (Gray), originally from Tanzania and housed at the Oklahoma City Zoological Park Herpetarium, Oklahoma County, Oklahoma, was found to be passing an undescribed species of Choleoeimeria in its feces. Oocysts of Choleoeimeria steveuptoni n. sp. were cylindroidal, 38.5 × 17.8 (36-42 × 17-19) µm with a bilayered wall and a shape index (len...

Two of 17 (12%) crevice bats, Tomopeas ravus (Chiroptera: Vespertilionidae), from Peru had coccidian oocysts in their feces when examined. Sporulated oocysts of Eimeria tomopea n. sp. are ellipsoid to subspheroid, 30.6 X 24.6 (26-34 X 20-28) micron with ovoid sporocysts 13.9 X 9.0 (12-15 X 8-10) micron. A micropyle and substieda body are absent, but polar bodies, oocyst and sporocyst residua, a...

Eimeria jirkamoraveci sp. n. is described from faeces of two specimens of the toad-headed, side-necked turtle Batrachemys heliostemma collected at Iquitos in Peru. Oocysts are ovoid to almost spherical, 10.6 (8-12) x 8.9 (7-10) microm, without micropyle, polar granule and oocyst residuum. One conically stretched end and three blunt conical tubercles at the opposite end of oocyst give it mitra-l...

Calcium in the flagellum controls sperm navigation. In sperm of marine invertebrates and mammals, Ca(2+) signalling has been intensely studied, whereas for fish little is known. In sea urchin sperm, a cyclic nucleotide-gated K(+) channel (CNGK) mediates a cGMP-induced hyperpolarization that evokes Ca(2+) influx. Here, we identify in sperm of the freshwater fish Danio rerio a novel CNGK family m...
