The notion that phenotypic traits emerging from environmental experiences are heritable remains under debate. However, the recent report of nonmendelian transgenerational epigenetic inheritance, i.e., inheritance not determined by DNA sequence, might make such a phenomenon plausible. In our study, carrying out common garden experiments, we could provide clear evidences that, on exposure to nonlethal heat shocks, parental population parthenogenetic (all female) Artemia (originating one single...
Abstract The brine shrimp Artemia is a highly required, convenient and cost‐effective live food used in fish shellfish larviculture. Its cysts, originating from limited number of inland salt lakes, are traded worldwide. Over the past decades, pond production solar saltworks, integrated with production, has emerged as an alternative to cope possible cyst shortages high prices on international market tool fulfill local biomass demands associated regional aquaculture developments. This article...
Encysted embryos (cysts) of the brine shrimp Artemia undergo diapause, a state profound dormancy and enhanced stress tolerance. Upon exposure to appropriate physical stimulus diapause terminates resume development. The regulation termination post-diapause development is poorly understood at molecular level, prompting this study on capacity hydrogen peroxide (H(2)O(2)) nitric oxide (NO) control these processes. Exposure H(2)O(2) NO, latter generated by use three NO generators, promoted cyst...
Abstract Bacterioplankton is an important component of marine as well fresh waters and accounts for a large fraction the production particulate matter in those ecosystems. The concept bacteria providers essential nutrients aquatic food webs has been raised most recently relation to utilization source aquaculture chains. This article represents comprehensive review on potential role direct organisms. After studying shortly analytical tools that can be applied determine uptake assimilation by...
Field surveys were conducted in order to collect information on the occurrence of wild Artemia populations hypersaline environments such as salt lakes, lagoons and salty rivers. The mating behaviour presence or absence males carefully recorded. Sampling involved use plankton nets. Collected cysts characterized basis their diameter chorion thickness, while nauplii (instar-I) total length. found at 17 different geographical locations scattered over 12 Iranian provinces. All are parthenogenetic...
Abstract Thus far, only one gene from the heat shock protein 70 ( HSP70 ) family has been identified in Artemia franciscana . Here, we used draft transcriptome database to search for other genes family. Four novel were and designated cognate HSC70 ), kDa 5 HSC70-5 Immunoglobulin heavy-chain binding (BIP) , hypoxia up-regulated 1 HYOU1 ). For each of these genes, obtained nucleotide deduced amino acid sequences, reconstructed a phylogenetic tree. Expression analysis revealed that juvenile...
Brine shrimp Artemia have an unequalled ability to endure extreme salinity and complete anoxia. This study aims elucidate its strategies cope with these stressors.
Abstract Decapsulated cysts of the brine shrimp Artemia franciscana were assessed as a factitious food for rearing anthocorid predator Orius laevigatus. Developmental and reproductive traits O. laevigatus reared single generation on A. from three geographical locations or gamma-irradiated eggs Mediterranean flour moth Ephestia kuehniella compared. There was no effect diet nymphal survival but period E. (12.2 days) 0.7–1.6 days shorter than diets. The developed 0.5–1 day faster San Francisco...
Abstract We studied the Artemia populations existing in Lake Urmia (north‐western Iran), one of largest habitats world, order to settle long‐standing controversy over sexual status endemic populations. Experiments were carried out laboratory and field. Cysts, collected from different sites lake peripheral lagoons, hatched cultured adults laboratory. Adult parthenogenetic animals isolated newly nauplii them maturity salinities, ranging 15–80 ppt. Survival levels percentage attaining adulthood...
We report on the construction of sex-specific linkage maps, identification sex-linked markers and genome size estimation for brine shrimp Artemia franciscana. Overall, from analysis 433 AFLP segregating in a 112 full-sib family we identified 21 male 22 female groups (2n = 42), covering 1,041 1,313 cM respectively. Fifteen putatively homologous groups, including sex were between map. Eight marker alleles inherited parent, supporting hypothesis WZ–ZZ sex-determining system. The haploid was...
Abstract The suitability of cysts the brine shrimp Artemia sp. as a factitious food for predator Macrolophus pygmaeus Rambur was investigated. influence decapsulation time and hydration on performance were studied in absence plant material. A longer had positive development predator. Hydration significant impact nymphal survival when where non‐decapsulated or poorly decapsulated. An experiment which nymphs switched from diet hydrated to non‐hydrated showed that material relative importance...
