EUCHROMA GIGANTEA PDF

Freely accessible to everyone, over half a million people every month, from over countries, used Arkive to learn and discover the wonders of the natural world. Since Wildscreen was unable to raise sufficient funds from trusts, foundations, corporates and individual donors to support the year-round costs of keeping Arkive online. Therefore, the charity had been using its reserves to keep the project online and was unable to fund any dedicated staff to maintain Arkive, let alone future-proof it, for over half a decade. Despite appeals for support, just 85 of our 5. As a small conservation charity, Wildscreen eventually reached the point where it could no longer financially sustain the ongoing costs of keeping Arkive free and online or invest in its much needed development.

Chromosome Res. Epub Mar 9. Insights into the karyotype evolution and speciation of the beetle Euchroma gigantea Coleoptera: Buprestidae. To better understand the complex karyotypic evolution of E. Herein, we used FISH with histone genes as well as sequencing of the COI to determine differential distribution of markers and relationships among populations.

The analyses revealed new karyotypes, with variability for chromosome number and morphology of multiple sex chromosome mechanisms, occurrence of B chromosome variants punctiform and large ones , and high dispersion of histone genes in different karyotypes.

These data indicate that chromosomal polymorphism in E. The COI phylogenetic and haplotype analyses highlighted the formation of three groups with chromosomally polymorphic individuals.

Finally, we compared the different karyotypes and proposed a model for the chromosomal evolution of this species. The species E. Moreover, in each of these lineages, different chromosomal rearrangements have been fixed. Dispersion of repetitive sequences may have favored the high frequency of these rearrangements, which could be related to both adaptation of the species to different habitats and the speciation process.
