سه گونه ماهی گل خورک periophthalmus waltoni، boleophthalmus dussumieri و scartelaos tenuis متعلق به خانواده گاوماهیان می باشند که در سواحل گلی جزر و مدی زندگی می کنند. با توجه به اینکه مطالعات کمی در خصوص زیست شناسی گونه های مذکور در ایران صورت نگرفته، بنابراین اهداف اصلی این پژوهش بررسی زیست شناسی تولیدمثل، رژیم و عادات غذایی و پویایی شناسی جمعیت این سه گونه ماهی می باشد. بدین منظور نمونه برد...

The usage of invasive tagging methods to assess lizard populations has often been criticised, due to the potential negative effects of marking, which possibly cause increased mortality or altered behaviour. The development of safe, less invasive techniques is essential for improved ecological study and conservation of lizard populations. In this study, we describe a photographic capture-recaptu...

length-weight relationships were estimated for three gobiid species of iran. significant length-weight relationships with high correlation coefficient were found for all species from eight localities. the value of the parameter b varied between 2.196-2.498 for boleophthalmus dussumieri (valenciennes, 1837); 2.554 to 3.460 for periophthalmus waltoni (koumans, 1955) and 2.316 to 2.920 for scartel...

By combining the spatio-temporal distribution of fish abundance and their size structure, and a detailed lifetime Sr/Ca ratio analysis in their otoliths, this study delineates the estuarine use and the movement patterns of seven sympatrical occurring adult mullets in the Tatu Creek estuary, central western Taiwan. In the estuaryMugil cephalus are the most dominant species, whereas Liza subvirid...

Alguns novos derivados de pirazol-5-carbonitrila 8,9 e pirazol-5-carboxamida 13 foram sintetizados pela reação de cicloadição de nitriliminas 3,4 a α-cianocinamonitrilas 5a-f e α-cianocinamamida 12a,b, respectivamente. Por outro lado, a adição de 3,4 a α-cianocinamato de etila 14a-f leva à produção de derivados de 2-pyrazoline-5-carboxilato de etila, 15, 16. Também, a cicloadição de 3,4 à 3-cia...

In the present study concentrations of 12 trace elements (TEs): As, Cd, Co, Cr, Cu, Fe, Hg, Mn, Ni, Pb, Se, and Zn were quantified in muscle and, where possible, liver tissues, six commercially important marine species including fish (Euryglossa orientalis, Sardinella longiceps, Carcharhinus dussumieri), crustacean (Portunus armatus, Thenus orientalis) mollusc (Sepia pharanois) collected from N...

Four new species of Ceratomyxa Thélohan, 1892 are described from the gall bladders of fishes collected off Lizard Island, Australia. These species are characterised using a combination of morphometric and molecular data. Ceratomyxa bartholomewae sp. n. is described from Hyporhamphus dussumieri (Valenciennes) (family Hemirhamphidae); C. koieae sp. n. is described from Sphyraena forsteri Cuvier (...

DNA barcoding is an effective method for identifying species by analyzing one or a few short standardized DNA sequences. In this study, we examined the utility of mitochondrial cytochrome oxidase subunit I (COI) sequences as a DNA barcode for the identification of six species belonging to the genus Thryssa: T. dussumieri, T. hamiltonii, T. kammalensis, T. mystax, T. setirostris, and T. vitriros...

Luring the snakes to climb the ropes by placing a dark cosy refuge at the top, Byrnes and Jayne filmed the animals’ ascents while measuring the tension on the rope as the animals coiled and uncoiled their grip. ‘All the climbing velocities were extremely slow,’ the duo says, ranging from 0.5 to 1 cm s–1 and the snakes only reached their top speeds on the thickest and tensest ropes. All of the s...
