Characterisation of Non-recognized Maternal Lines of the Croatian Lipizzan Horse Using Mitochondrial DNA

Under the assumption that some of the unrecognized Lipizzan lines originate from one of the classical female lines, the main goal of this studies was to prove that stud book data was not kept adequately. Since in the framework of LIF the conducted INCO Copernicus project „Biotechnical methods in the maintenance of genetic diversity of the Lipizzan horse breed“ comprised the research of the genetic structure of the entire studfarm Lipizzan horse population in European national stud farms, it was possible to compare its results to the results of this research and confirm or disprove set hypothesis. Analysed mares in the stud books of the Stud Farm of Ðakovo are introduced as representatives of five families: Beba – Elza, Cura – Lela, Lenica – Lasta, Liza – Cica and Liza – Pliva. Characterising of mitochondrial genome has confirmed negligent record keeping of origin in private breeding. Some non-recognised families are descendants of recognised Lipizzan families. Haplotype Allegra is found in the family of Liza-Cica-Pliva, and haplotype Capriola in the family of Cura-Lela. Both haplotypes are very common in the Lipizzaner breed and inherent to classic Lipizzan families

IZVANKURIKULARNE SPORTSKE AKTIVNOSTI DJECE PREDŠKOLSKE DOBI: UTJECAJ NA MOTORIČKA POSTIGNUĆA I TJELESNU PISMENOST

The aim of the research was to determine the influence of an extracurricular sports program on motor abilities and physical literacy of preschool children aged from 4 to 6 years. For this purpose, the battery of six motor tests of known metric characteristics was used to measure the following motor abilities: coordination, strength, flexibility and balance. The data were calculated by descriptive statistics. The differences in motor abilities between two time points (initial and final), as well as the interactional effect of a single variable on the global results of motor abilities in repeated measurement with regard to the point of measurement and gender, were calculated by multivariate analysis of variance. The obtained results have confirmed the previous findings describing the benefits of continuous physical activity for the development of preschool children motor abilities and physical literacy. The results are also consistent with the previous research showing that boys have better achievements in explosive strength and coordination, whereas girls have better achievements in dynamic strength, flexibility and balance.Istraživanje je provedeno u svrhu utvrđivanja utjecaja izvankurikularnog sportskog programa na motorička postignuća i tjelesnu pismenost djece u dobi od 4 do 6 godina. U tu svrhu primjenjena je baterija od šest motoričkih testova poznatih metrijskih karakteristika namijenjenih procjeni koordinacije, tjelesne snage, gibljivosti i ravnoteže. Na rezultatima su izračunati parametri osnovne deskriptivne statistike, multivarijatnom analizom varijance izračunate su promjene u motoričkim sposobnostima između dva mjerenja (početno i završno) te interakcijski efekt pojedine varijable u ponovljenom mjerenju na globalne rezultate motoričkih sposobnosti u odnosu na točku mjerenja i u odnosu na spol. Rezultati su potvrdili dosadašnje spoznaje koje se odnose na pozitivan utjecaj redovitog tjelesnog vježbanja na razvoj motoričkih sposobnosti i međupovezno tjelesne pismenosti predškolaca. Osim toga sukladno rezultatima prethodnih istraživanja utvrđene su statistički značajne razlike u motoričkim postignućima između djevojčica i dječaka, dominacija dječaka u rezultatima motoričkih testova namijenjenih procjeni eksplozivne snage i koordinacije, a djevojčica u testovima dinamičke snage, gibljivosti i ravnoteže

Vertical distribution of periphytic diatoms in the karstic Zrmanja River (Croatia)

The small karstic Zrmanja River (69 km long) discharges into the central-eastern Adriatic Sea. High oxygen saturation and water transparency, as well as low nutrient concentrations, indicated the oligotrophic character of the river.We present the taxonomic composition and vertical distribution of diatoms attached on an artificial substrate (Plexiglass) in the lower reach of the Zrmanja River, in July 2000. Thirty attached diatoms were determined on Plexiglass throughout the 2.5 m deep water column, and Achnanthes sp. and Fragilaria sp.were found to be the most frequent (> 89%) and abundant (> 105 cells cm–2) diatoms. The highest abundance of attached diatoms (1.2 x 106 and 7.5 x 105 cells cm–2) was found at the depth of 0.5 m. The maximum number of diatom taxa was also found below the surface
