The effects of mate switching tacticon reproductive performance of the severum cichlid, Herosseverus
This study investigated the effects of mate switching on the reproductive performance of the severum cichlid, Herosseverus, by advancing the egg and larval production in hatcheries. Two reproductive tactic treatments of “monogamous pair” and “mate switching” were used for evaluating 4 reproductive traits of egg production, hatching rate, spawning intervals, and starvation tolerance of the larva...

Sarta longhorned beetle, Aeolesthes sarta, is one of the most destructive wood borer pests of fruit and shade trees in Iran. In this research, the reproductive parameters were studied under laboratory conditions. Fifteen pairs of newly developed adults (1-2 days after emergence from overwintering sites) were caged separately on 15 logs of Ulmus carpinifolia and fertility table was made using th...
this study investigated the potential role of age in inductive and deductive grammar learning among iranian foreign language learners. the experimental population consisted of our randomly selected samples including two groups of children (with age of exposure to english within 8-13), and two groups of adults (with age of exposure to english within 11-13). thus, the comparison was between ch...
Reproductive tactics of some insects are affected by photoperiod because daylength is a reliable cue indicating seasonal change in environmental suitability. We tested the hypothesis that late-season (short-day) photoperiod affects the length of the oviposition cycle of the eastern lubber grasshopper, which is from a subtropical area with a winter dry season.We predicted that oviposition wouldo...
The current study was carried out to evaluate the effect of phytogenic feed additive (PFA) on egg production performance in Hy-Line brown layer birds. A flock size 14190 birds selected commercial poultry farm which maintained with standard management practices at Spain. baseline data (T1) recorded for 20 days, thereafter, were fed PFA (500 g/ton) (T2) supplemented 11 days. parameters viz. numbe...
Influence of Smoking Time and Number of Cigarettes Smoked per Day in Oral Characteristics of Smokers
The aim of this study was to identify the optimal storage duration of incubated eggs of Dandarawi hens on embryonic mortality, hatchability, one-day chick weight and viability of chicks at 14 days of age. Eggs were collected 4 times daily for 15 consecutive days and stored at 16°C and 70% RH until sorted into treatments and then were incubated for 21 d under standard incubation conditions. The ...
