Key role and diversity of EcR/USP and other nuclear receptors in selected Arthropoda species
… sequencing projects that are carried out for Arthropoda is rapidly increasing. This gave us the opportunity to investigate the NRs in a number of other arthropods and compare the sets of NRs between some of these groups. We chose three species, the hemimetabolic pea aphid Acyrthosiphon pisum, …

A cause for consilience: Utilizing multiple genomic data types to resolve problematic nodes within Arthropoda and Ecdysozoa
… Priapulida, Tardigrada, Onychophora and Arthropoda). Ecdysozoa is the most specious clade of animals to ever exist and the relationships among its eight phyla are still heatedly debated. Similarly also the relationships among the three sub-phyla (Chelicerata, Pancrustacea and Myriapoda) …

A molecular phylogeny of the families and orders of Collembola (Arthropoda: Hexapoda) using the 18S rDNA gene
In this study I investigate the phylogenetic relationships of the families and orders of Collembola, with special reference to six groups that traditionally have been problematic, or that have become problematic with the implementation of the cladistic philosophy to the systematics of the group. …

Characterization of C-Gmp Dependent Kinases Within the Circadian Molecular Clockworks: Structural, Phylogenetic, and Functional Analyses
… metazoans actually occurred before the Arthropoda split from the Chordata lineage and that the Prkg2 gene is the ancestral gene of the cGK family. Homology based structural models of the functional domains of the cGK family indicate impressive conservation within the cyclic nucleotide …

The taxonomy of a Pentastomid parasite from an Indian Calotes versicolor
… Class Pentastomida is ranked under the Phylum Arthropoda by most authors, but its position is questionable in view of its unusual body structure, and probably the group should be regarded as occupying an isolated place among the invertebrates. The members of the Class Pentastomida are …

Reproductive biology, morphology and diet of Raja straeleni (spotted skate) in South Africa
… were recorded. In terms of %frequency they were Arthropoda (17%), Chordata, (8.2%), Mollusca (4.5%), Echinodermata (1.9%), Annelida (1.9%), and Nemertea (1.9%). The trophic level of R. straeleni was 3.98 ±0.05 SE. The trophic level was previously calculated as 3.74 (n = 421) (Ebert and Bazzarro …

Multi-Modal Effects of the Repellent Deet Across Protostomia
… neurons required for DEET-sensitivity outside of Arthropoda, we turned to the nematode C. elegans. Here, we demonstrated that DEET affects chemotaxis to some odors but not others. We used this behavior as the basis for a forward genetic screen, and identified two genes as candidates required for …

Biodiversity and systematics of parasitic Crustacea infesting southern African freshwater fishes
Crustaceans (Arthropoda: Crustacea) are regarded as the most morphologically diverse group in the phylum Arthropoda, and they have the greatest diversity of parasitic forms. Parasitic crustaceans have adapted several morphological and physiological characteristics that enable them to thrive in an …

Die antennalen Sensillen von Dipterenlarven und Larven verwandter Insektenordnungen
Sensillen sind „Kleinsinnesorgane“ der Arthropoda, die die Wahrnehmung einer Vielzahl unterschiedlicher Reize ermöglichen. Trotz großen Interesses an diesen Sinnesorganen ist die Frage nach den Homologieverhältnissen und der Evolution von Sensillen weitgehend ungeklärt. In der vorliegenden Arbeit …

Influence of living and non-living habitat complexity on arthropods in strip-tilled cabbage fields
Vegetational (living) and structural (non-living) complexity can influence arthropods in agricultural systems. In this thesis, both forms of complexity were manipulated in cabbage fields. In 2010 and 2011, a field experiment was conducted examining the effects of herbicide intensity and oat kill …
