Sicily (Italy) hosts a "relict", endemic population of the birds Alectoris graeca whitakeri commonly known as Sicilian Rock Partridge. In last decades, due to risk restocking with other European and Asiatic species for hunting purpose, study was carried out investigate potential hybridisation. The mtDNA control-region nuclear microsatellites were genotyped. Due importance species, samples mainl...

The study included 144 fishes in Lake of 16 Tishreen Dam for detecting the infection with parasitic Protozoans, and determine distribution rate. Fishes were collected randomly once a month, during period from 22/12/2011 until 22/12/2012. Collected samples belonged to following species: Cyprinus carpio L., Varicorhinus damascinus, Garra rufa, Tilapia zillii, Liza abu. T. zillii was most prevalen...

Double-nesting behaviour, a rare breeding system in which females lay in two nests, one incubated by herself and the other one by her mate, could be considered an intermediate stage in the evolutionary trend from biparental to uniparental care of single clutches. We examined the occurrence and success of double-nesting behaviour in Red-legged Partridges Alectoris rufa in Central Spain. Clutch s...

Seafood mislabeling distorts the true abundance of fish in the sea, defrauds consumers, and can also cause unwanted exposure to harmful pollutants. By combining genetic data with analyses of total mercury content, we have investigated how species substitutions and fishery-stock substitutions obscure mercury contamination in Patagonian toothfish (Dissostichus eleginoides), also known as "Chilean...

Trichoderma (Ascomycetes, Hypocreales) strains that have warted conidia are traditionally identified as T. viride, the type species of Trichoderma. However, two morphologically distinct types of conidial warts (I and II) have been found. Because each type corresponds to a unique mitochondrial DNA pattern, it has been questioned whether T. viride comprises more than one species. Combined molecul...

Relative weights of heart, spleen, pancreas, and liver and the relative lengths of the small intestine and the cecum were taken from 40 farm-bred and 43 wild juvenile red-legged partridges (Alectoris rufa Linnaeus) in central Spain. Expressed as a ratio to head and body length, farm-bred partridges had lighter hearts (17% lighter), spleens (78%), and livers (29%) and shorter small intestines (1...

A new test system for the detection of plant growth regulating activities was successfully employed. In a screening for inhibitors of the gibberellic acid controlled synthesis of hydrolytic enzymes in embryoless wheat seeds (Triticum aestivum) 160 cultures of ascomycetes and basi­ diomycetes were tested. In the extracts of two cultures inhibitory activities were detected. From fermentations of ...

The Iranian cave barb (Iranocypris typhlops Bruun & Kaiser, 1944) is a rare and endemic species of the family Cyprinidae known from a single locality in the Zagros Mountains, western Iran. This species is "Vulnerable" according to the IUCN Red List and is one of the top four threatened freshwater fish species in Iran. Yet, the taxonomic position of I. typhlops is uncertain. We examined phylogen...
