Reproductive traits are among the most important biological characteristics that facilitate or impede establishment of non-native fish into new environments. In several tributaries Lower River Danube (Bulgaria), round goby (Neogobius melanostomus Pallas, 1814) is a recent invader. Specimens from edge invasion front were collected monthly (March 2017 to May 2018) each river. The pioneer individu...

Background: The quality and quantity of the diet has undeniable effects on the reproduction of organisms. We examined the effects of two diets (with and without mineral supplementation-Vitamins) on super-ovulation in two strains of mice (B6D2F1 and NMRI) in Royan Institute, Tehran. Materials and Methods: For this purpose, 40 female mice (21 days) from each strain were divided into four experime...

Twenty-one pregnant ewe lambs (nine superovulated and 12 non-superovulated) were used to study the effects of superovulation (injecting 700 IU PMSG at the end of diestrus) on maternal serum progesterone concentrations, uterine and fetal weights at weeks 7 and 15 of pregnancy. In the ewes sacrificed at week 7 of pregnancy, superovulation increased the mean number of corpora lutea (P<0.01), fetus...

23 24 Beside biotic interactions, habitat preference and dispersal ability of species play a prominent 25 role in the building of animal species assemblages. However, these traits are usually very poorly 26 documented for soil organisms. A soil transfer experiment was designed to study habitat preference 27 (including land-use and soil preference) and dispersal ability of soil springtail specie...

35 The cortical potentials evoked by cutaneous application of a laser stimulus (laser evoked 36 potentials, LEP) often include potentials in the primary somatic sensory cortex (S1), which may 37 be located within the subdivisions of S1 including Brodmann areas 3A, 3B, 1 and 2. The precise 38 location of the LEP generator may clarify the pattern of nociceptive activation of human S1 by 39 painfu...
