A long-awaited book about fossil arachnids Book review: Dunlop JA, Penney D (2012) Fossil Arachnids. Monograph Series Volume 2. Siri Scientific Press, Manchester, 192 pp.
For a long time palaeoarthropodology has been ticking over in the background with publications mainly restricted to taxonomic papers in scientific journals. The deficit of more general overview works as a resource of background information for neontologists as well as palaeontologists was recently addressed for insects (Rasnitsyn and Quicke 2002; Grimaldi and Engel 2005). Now, for the first tim...
متن کاملArachnid envenomation.
This article focuses on the medically relevant arachnid species found in North America and selected other arachnids from around the world. While it is largely still true that the geographic location of the envenomation assists in determining the species responsible, the booming trade in arachnids as exotic pets should prompt the clinician to inquire into this possibility. Expert advice should b...
متن کاملDiversity of Tropical Spiders - Ground-dwelling Species of Brazilian Savannas
Spiders are one of the biggest and most diverse groups of arthropods. There are around 40000 described species of spiders, belonging to more than 100 families and 3600 genera. However, 170000 species of these arachnids are estimated to exist in the world, which reflects the scantiness of studies about this group. The distribution and diversity of spiders in macro and micro-scale in the tropics ...
متن کاملParallel evolution of truncated transfer RNA genes in arachnid mitochondrial genomes.
The cloverleaf secondary structure of transfer RNA (tRNA) is highly conserved across all forms of life. Here, we provide sequence data and inferred secondary structures for all tRNA genes from 8 new arachnid mitochondrial genomes, including representatives from 6 orders. These data show remarkable reductions in tRNA gene sequences, indicating that T-arms are missing from many of the 22 tRNAs in...
متن کاملAn Analysis of the Secondary Structure of the Mitochondrial Large Subunit rRNA Gene (16S) in Spiders and Its Implications for Phylogenetic Reconstruction
We investigated the pattern of molecular variation with respect to secondary structure in the 16S ribosomal RNA gene and its phylogenetic implications for arachnids with a focus on spiders. Based on a model by Gutell et al. (1996), secondary structures were proposed for the 39 half of 16S in the mygalomorph spider Aptostichus atomarius. Models were also constructed for a hypervariable length of...
