Zbog svog jakog otrova spada među najotrovnije pauke. Detaljan opis različitih staništa i populacija za područje mediteranske Hrvatske do sada nije rađen. U ovom istraživanju se uz pomoć novijih znanstvenih metoda, npr. primjenom data loggera za mjerenje mikroklimatskih uvjeta u staništu, te analizom prehrambenih navika želi doznati više o načinu života ove vrste na različitim staništima u Hrvatskoj. Istraživanjem se provjeravaju svi literaturni nalazi u svrhu njihove potvrde te utvrđuju nova staništa na kojima je zabilježena, kao i određeni ekološki čimbenici prezimljavanja adultnih ženki. Kao zasebni segment ovog doktorskog rada, na temelju analize mitohondrijskog DNA biljega, istražuje se genetska raznolikost i filogeografska struktura vrste na području cijelog hrvatskog priobalja i nekih otoka.- Mediterranean Black widow Latrodectus tredecimguttatus inhabits the southern part of Europe and Asia. In Croatia it is present in Istria, Primorje region, some islands and Dalmatia. Because of its strong venom black widow is one of the most poisonous spiders. Description has not been researched of the various habitats and populations in the Croatian coast. The aim of this study is to learn more about the life of species in different habitats using new scientific methods such as data loggers for measuring microclimate conditions in habitat and analysis of dietary habits. The study checks previous literature as well as it determines new habitats on witch the subject was noted. It also defines specific ecological factors about wintering of adult females. Based on mitochondrial genetic marker, genetic diversity and phylogeographic structure of the species will be estimated throughout its distribution area along the eastern Adriatic coast and some of the islands.- All metadata published by Europeana are available free of restriction under the Creative Commons CC0 1.0 Universal Public Domain Dedication.

Provider: - Institution: - Data provided by Europeana Collections- Filogenetska i filogeografska analiza bialelnih i mikrosatelitnih biljega kromosoma Y u visokoj rezoluciji provedena je na uzorcima ...720 ispitanika iz četiri kontinentalne i osam otočnih subpopulacija Hrvatske. Dobiveni rezultati su zatim stavljeni u širi europski kontekst usporedbom sa bazama podataka iz drugih europskih populacija. U ukupnom je uzorku utvrđen visok stupanj genetičke raznolikosti i prisutnost svih tipičnih europskih haplogroupa s uobičajenim obrascima širenja za ovo područje. No na razini pojedinih subpopulacija su zamijećene razlike u frekvenciji određenih haplogrupa zbog utjecaja evolucijskih sila. Tri najčešće haplogrupe su bile u središtu interesa ove studije. Analize dominantne i autohtone I2a2-M423 linije (>30%) potvrđuju pretpostavku o postojanju Balkanskog refugijuma u vrijeme paleolitika na ovom području, linija R1a1a1c*-M558 (19%) predstavlja signal iz područja Europe čije stanovništvo govori slavenskim jezicima u populaciji Hrvatske, a filogeografija E1b1b1a2-V13 haplogrupe (9%) upućuje na obrazac kulturalne difuzije zemljoradnje u Europi.- A high-resolution phylogenetic and phylogeographic analysis of SNPs and STRs on the Y chromosome was performed on 720 samples from four continental and eight insular Croatian subpopulations. The obtained results were then placed in a wider European context by comparing them with a large dataset from other European populations. A high diversity of haplogroups was observed in the overall sample, and all typical European Y chromosome haplogroups with corresponding clinal patterns were observed. However, the frequencies of certain haplogroups differed significantly across some subpopulations due to the effect of evolutionary forces. Three major Y chromosome haplogroups were in the focus of this study. The analyses of the dominant and autochtonous I2a2-M423 lineage (>30%) suggest the existence of the Balkan refugium in the Paleolithic, the R1a1a1c*-M558 lineage (19%) represents a signal from present day Slavic populations from nothern/central Europe in the Croatian population and the phylogeography of the E1b1b1a2-V13 clade (9%) implies cultural diffusion of agriculture into Europe.- All metadata published by Europeana are available free of restriction under the Creative Commons CC0 1.0 Universal Public Domain Dedication.
