Exploring The Neuropeptides, Neuropeptide Receptors And Neurotransmitter Receptors In The Synganglia Of Part-Fed Females Of Ornithodoros Turicata (Argasidae) And Ixodes Scapularis (Ixodidae) With Insights Into Their Roles In Contrasting Biology, Noble I. Egekwu
Theses and Dissertations in Biomedical Sciences
The neurobiology of the synganglion (central nervous system) of the Lyme disease tick, Ixodes scapularis and the soft tick Ornithodoros turicata was evaluated using Illumina GAII high throughput sequencing which generated high coverage cDNA libraries (transcriptomes). These ticks exhibit different biological patterns of feeding, blood meal water, and salt elimination, cuticle plasticity versus cuticle synthesis, development and reproduction. RNA sequencing of I. scapularis, and Ornithodoros turicata yielded a total of 117,900,476 raw reads which were assembled to 30,838 contigs and a total of 63,528,102 also assembled to 132,258 contigs, respectively. Comparison of Gene Ontology (GO) mapping success for genes …

Biological Sciences Theses & Dissertations
Reproductive skew, the degree to which reproduction is shared among same-sex individuals in a social group, is a pattern affected by ecological conditions, sociality, cooperation, and the inter- and intrasexual behavior of individuals in complex animal societies. Transactional and compromise skew models assume that high skew is the product of dominance hierarchies among cobreeders, yet this has rarely been tested. Both model types fail to incorporate the decisions of more than two individuals, generally overlooking the effect of female behavior on male reproductive success in multi-male groups, and are ineffective at predicting skew in larger groups characterized by more than …
