Ampelisca lusitanica (Crustacea: Amphipoda): new species for the Atlantic coast of Morocco
Background
This study reports for the first time the presence of the Lusitanian ampeliscid amphipod Ampelisca lusitanica Bellan-Santini & Marques, 1986 in the northwestern Atlantic coast of Morocco.
Methods
Specimens were collected in January 2015 from intertidal rock pools along the El Jadida shoreline associated with the brown algae Bifurcaria bifurcata and Sargassum muticum.
Results
Systematic description of the species is presented, as well as a discussion of its ecological and geographical distribution.
Conclusion
This new finding extends the geographical distribution from the Lusitanian (Europe) to the Mauritanian (Africa) region and increases knowledge of the ecology and the global distribution of A. lusitanica found, previously, only on Portuguese and Spanish coasts.info:eu-repo/semantics/publishedVersio
A first AFLP-based genetic linkage map for brine shrimp Artemia franciscana and its application in mapping the sex locus
We report on the construction of sex-specific linkage maps, the identification of sex-linked markers and the genome size estimation for the brine shrimp Artemia franciscana. Overall, from the analysis of 433 AFLP markers segregating in a 112 full-sib family we identified 21 male and 22 female linkage groups (2n = 42), covering 1,041 and 1,313 cM respectively. Fifteen putatively homologous linkage groups, including the sex linkage groups, were identified between the female and male linkage map. Eight sex-linked AFLP marker alleles were inherited from the female parent, supporting the hypothesis of a WZ-ZZ sex-determining system. The haploid Artemia genome size was estimated to 0.93 Gb by flow cytometry. The produced Artemia linkage maps provide the basis for further fine mapping and exploring of the sex-determining region and are a possible marker resource for mapping genomic loci underlying phenotypic differences among Artemia species
Social-pedagogical Aspects Resocialization of Pupils of the Centers Social-psychological Rehabilitation of Children
The article substantiates the notion of pedagogical support of resocialization of pupils of centers of social-psychological rehabilitation of children as a complex of pedagogical means, mechanisms and forms of their realization. This support favors the activation of own experience and potential of pupils. It also widens possibilities of the learning-upbringing system of centers of social-psychological rehabilitation of children for increasing the effectiveness of the process of pupils' resocialization. There were characterized the components of the pedagogical support of the process of resocialization of pupils of centers (aim, principles, content, directions, mechanisms and forms of their realization). The aim of the pedagogical support of the process of resocialization of pupils of centers is to favor the overcoming of obstacles or lag in the process of children's socialization using the complex of correcting-rehabilitating forms of the social-pedagogical work. There were determined the principles of the pedagogical support of resocialization of pupils of centers: the principle of purposefulness, reflexivity, partnership, subjectivity, synergy, unity of the learning, upbringing and correcting work at realizing resocialization tasks. There were separated the content directions of the pedagogical support:– formation and assimilation of democratic culture skills;– realization of civic duties;– taking of responsibility (for oneself, family, society);– formation of integral worldview;– mastering of social skills;– conscious choice of life strategies;– realization of rights, possibilities and motivation of the future social and professional development;– development of communication skills, communication culture;– development of self-cognition, self-appraisal, self-determination.There were determined the mechanisms of introduction of the pedagogical support of the process of resocialization of pupils of centers of social-psychological rehabilitation of children: – mechanism of favoring pupils' participation in the process of resocialization;– mechanism of activation of the work of social teachers and psychologists of centers;– mechanism of involving, parents, persons, who replace them and tutors of pupils of centers to the cooperation in the direction of resocialization.The effectiveness of the elaborated pedagogical support of the process of recosialization of pupils of centers and forms of the social-pedagogical work with them was proved. There were presented the complex program of resocialization of pupils of centers “You are able to more!”, forms of the social-pedagogical work with parents (persons, who replace them) of pupils and specialists of centers of social-psychological rehabilitation of children (lecture, pedagogical seminar
