Functional Morphology and Evolu Tion of Xiphosurids
Func tional morphol ogy and evolu tion of xiphosurids JAN BERGSTROM Bergstrom, J. 1 975 07 15: Functional morphology and evolution of xiphosurids. Fossils and Strata, No. 4, pp. 291-305, Pl. 1. Oslo. ISSN 0300-9491. ISBN 82-00-04963-9. Aspects of the morphology, evolution and systematics of the Xiphosurida are treated. The ancestrai forms lacked specialization for ploughing, and their chilaria were evidently developed as prosomal walking legs. The cor responding tergite (of the pregenital segment) was probably separate from the main prosomal shield in the early xiphosurids as well as in the eurypter ids. From this stem two main groups seem to have evolved. One consists of the synziphosurids, large-eyed eurypterid-like hunters with stri king opistho somal tagmosis. The other consists of the burrowing and ploughing xipho surids, in which the opisthosomal tergites were subject to progressive fusion ending with a single opisthothoracic tergal shield in the Late Palaeo zoic. The last prosomal appendages evolved into the chilaria, if this did not happen earlier, and the corresponding free tergite disappeared. Probably in Carboniferous time the limulines came into existence through a sudden displacement of the prosomal/opisthosomal boundary. Jan Bergstram, Department of His torical Geology and Palaeontology, Un iversity of Lund, Solvegatan 13, S-223 62 Lund, 1st August 1973. The Xiphosura may be considered to constitute a subdass or dass of chelicerate arthropods. The delimitation has been diseussed in the past, but no general agreement seems to exist. Generally, the xiphosurids are induded with the aglaspidids and eurypterids in the Merostorna ta. However, as generally understood, this taxon probably represents an evolutionary grade rather than a phylogenetic unit. -
Key to Common Indoor Spiders Found in Utah
KEY TO COMMON INDOOR SPIDERS FOUND IN UTAH Alan H. Roe Insect Diagnostician Utah Plant Pest Diagnostic Lab November 2005 This key is intended as an identification aid for spider specimens commonly collected from indoor situations in Utah. It is not all-inclusive and will not correctly identify all spiders. However, the key does include groups that comprise about 90% of the specimens that are submitted from household situations in Utah, and about 80% of spiders submitted from all situations. This simplified key is designed for use by persons with a minimal knowledge of spider anatomy. Anatomical characteristics utilized by the key include eye arrangements, the number of claws on the tarsi, the presence or lack of claw tufts, the appearance of the spinnerets, and the arrangement of teeth (if any) on the rear margin of the cheliceral fang furrow. Actual photographs of spider anatomy are utilized to illustrate the various characteristics described in the key. A dissecting microscope (20X minimum power) is recommended to observe the necessary characteristics. One or two pairs of fine forceps and a dissecting pin are useful for manipulating specimens. A silicone-filled dissecting dish and insect pins may also be useful for holding specimens in the required viewing positions. Ethyl alcohol (70%) is recommended for preserving spider specimens. Specimens can be viewed submerged under alcohol or dry, but dry specimens are prone to breakage. Spiders included in this key are identified to the family, genus, or species level. A list of these spiders and their classification level is given in the table below. The actual key follows the table. -

Difficult to see without a microscope, most microarthropods are between a 0.1 and 2 mm in length. Though they exist much deeper, microarthropods are most abundant in first 5 centimeters of soil where they can reach 70,000 per square meter in early successional alder stages and a million per square meter in mature white spruce stands. These arthropods occupy at least the first couple meters in unfrozen boreal soil decreasing in numbers with depth. We are studying the development of microarthropod communities in three forest stand types along the Tanana River floodplain: early- succession alder, mid-succesion balsam poplar, and late- succession white spruce. -
Investigation of Hox Gene Expression in the Brazilian Whiteknee Tarantula Acanthoscurria Geniculata
Investigation of Hox gene expression in the Brazilian Whiteknee tarantula Acanthoscurria geniculata Dan Strömbäck Degree project in biology, Bachelor of science, 2020 Examensarbete i biologi 15 hp till kandidatexamen, 2020 Biology Education Centre and Institutionen för biologisk grundutbildning vid Uppsala universitet, Uppsala University Supervisor: Ralf Janssen Abstract Acanthoscurria geniculata, the Brazilian whiteknee tarantula, is part of the group Mygalomorphae (mygalomorph spiders). Mygalomorphae and Araneomorphae (true spiders) and Mesothelae (segmented spiders) make up Araneae (all spiders). All spiders have a prosoma with a pair of chelicerae, pedipalps and four pairs of legs, and an opisthosoma with two pairs of book lungs or one pair of book lungs and one pair of trachea (in opisthosomal segments O2 and O3) and one or two pairs of spinnerets (in segments O4 and O5). The mygalomorphs have retained two pairs of book lungs, an ancestral trait evident from looking at Mesothelae, the ancestral sister group of both Araneomorphae and Mygalomorphae. The spinnerets differ greatly between the groups, but this study focuses on comparing Mygalomorphae and Araneomorphae. Mygalomorphae also have reduced anterior spinnerets, but instead enormous posterior spinnerets. Araneomorphae possess all four, but none particularly big. The genetic basis of these differences between the set of opisthosomal appendages in tarantulas and true spiders is unclear. One group of genes that could be involved in the development of these differences could be the famous Hox genes. Hox genes have homeotic functions. If they are expressed differently between these two groups, the resulting morphology could change. This study focuses on the posterior Hox genes in A. geniculata, i.e. -
