Parasites of the eyes of fresh and brackish water fishes in Iran
In the present investigation a total of six parasite species, some eye-specific and others non-organ specific parasites were found in the eyes of 48 examined fish species, collected from fresh and brackish waters of Iran during 2004-2006. Ichthyophthirius multifiliis was isolated from the external surface of the eyes of Oncorhynchus mykiss, Gyrodactylus stankovici from Cyprinus carpio and Lern...
متن کاملLeaf-inhabiting genera of the Gnomoniaceae, Diaporthales
The Gnomoniaceae are characterised by ascomata that are generally immersed, solitary, without a stroma, or aggregated with a rudimentary stroma, in herbaceous plant material especially in leaves, twigs or stems, but also in bark or wood. The ascomata are black, soft-textured, thin-walled, and pseudoparenchymatous with one or more central or eccentric necks. The asci usually have a distinct apic...
متن کاملRegulation of water and some ions in Gammarids (Amphipods). I. Gammarus duebeni Lilljeborg from brackish water and fresh water.
Previous work on Gammarus duebeni from brackish and fresh waters established that a correlation exists between certain features of sodium regulation and the sodium concentration of the particular habitat occupied by a population. In populations from fresh water sodium losses in the urine are reduced and the transporting system at the body surface has a higher affinity for sodium ions (Sutcliffe...
متن کاملThe Energetics of Osmotic Regulation in Brackish- and Fresh-water Animals
INTRODUCTION The classical work of Griffiths (1891) and Fredericq (1901) more than half a century ago showed that fresh-water animals are hypertonic to the media in which they live. If the body wall of a fresh-water animal is permeable to water the animal will suffer from an osmotic inflow of water. Overton (1904) first suggested that the excretory organ of a fresh-water animal helped to balanc...
متن کاملTemperature and salinity constraints on the life cycle of two brackish - water nematode species
The present study investigates the influence of salinity and temperature on the life history of two estuarine bacterivorous nematode species, Pellioditis marina and Diplolaimelloides meyli, isolated from the mesohaline zone of the Westerschelde Estuary, SW Netherlands. Gravid females and adult males were inoculated in petri dishes containing agar layers of nine (for P. marina) or five (for D. m...
