Vegetation patterns and plant reproductive processes in the succulent Karoo
… thesis focuses on vegetation patterns and plant reproductive processes at the Tierberg Karoo Research Centre (33°1 0'S, 22°17'E) in the semi-arid southern Succulent Karoo, South Africa. It begins with an investigation into the roles of soil properties and competition in explaining variation in …

Reconstructive and reproductive processes in children's recall for prose structure and content
… explored the interaction of reconstructive and reproductive memory processes in children’s recall for stories. Specifically, kindergartners, second-graders, and fourth-graders were compared on accuracy measures of both recall structure and content as a function of the form of the presented story …

Sublethal effects of cadmium and diazinon on reproduction and larval behavior in zebrafish (Brachydanio rerio)
… reproduce. Thus, environmental perturbation of reproductive processes could have significant ecological impacts. Fish are often exposed to lethal and sublethal contaminant concentrations. At sublethal concentrations, there is still a concern that contaminant exposure may influence life history …

Design and Synthesis of Novel Core Scaffolds for the Development of Subtype Selective Estrogen Receptor Ligands
… in bone maintenance, cardiovascular function and reproductive processes in both men and women. Although the two subtypes of ER---ERalpha and ERbeta---share 96% homology in their DNA-binding domains, their ligand-binding domains share only 59% homology, allowing for the design of subtype-specific …

Endocrine control of fat body composition and effects of the insect growth regulators methoprene and pyriproxyfen on the development and reproduction of the Argentinian cockroach, Blaptica dubia Serville (Blattaria: Blaberidae)
… of adult females are closely related with the reproductive processes of ovarian growth, ootheca formation, ootheca deposition, and hatching of the nymphs. The biochemical composition of the fat body was analyzed and revealed the storage lipids as main constituents, followed by glycogen, …

Elucidating the Function of Krüppel Homolog 1 (Kr-h1) Associated Proteins (KAPs) in Aedes aegypti Reproduction Through RNA Interference-Mediated Downregulation
… Krüppel homolog 1 (Kr-h1) is crucial in multiple reproductive processes of Aedes aegypti mosquitoes, including previtellogenesis, vitellogenesis, and oogenesis. This study explores the interaction between Kr-h1 and its potential associated proteins (KAPs), with a specific focus on the dimerization …

Investigation of differential TNFα-induced interleukin-6 gene regulation by synthesis progestins medroxyprogesterone acetate (MPA) and norethindrone acetate (NET-A) in human endocervical epithelial cells and the role of the unliganded glucocorticoid receptor
The endocervical mucosae of the female reproductive tract (FRT) not only serve as a physical barrier against microbial infection, but they also express a wide variety of immune mediators. The endocervical epithelial cells express a distinct profile of immune-regulators, which is higher than vaginal …

Ecotoxicology and ecophysiology of mysids, with special reference to copper toxicity in Praunus flexuosus
… of 7.9µg g<sup>-1</sup> dry weight day per day. Reproductive processes were severely disrupted at any copper treatment. Production of juveniles was reduced to zero, because of the high abortion rate, reduction on brood survival and damage to fertilisation processes.

Function and evolution of seminal fluid components in Drosophila
… fluid proteins (SFPs) secreted by the male reproductive tract are transferred to females during mating and induce profound female post-mating behavioral and physiological shifts. Many SFPs work in concert with female-derived molecules to promote fertility. However, reproductive fluids are a …

Effects of prenatal androgenization on hormones of growth and reproduction in cattle
… of hormones that regulate growth and reproductive processes in cattle. In Experiment 1, the efficacy of Synovex$\sp\circler$H as an agent for prenatal androgenization was evaluated in 15 pregnant beef heifers. Fifteen additional heifers were used as controls. During the 84-day blood …

Physiological and transcriptomic responses of soybean reproductive development to global climate change
… effects on crop yield have focused on leaf-level processes, while less effort has been placed on understanding the response of reproductive organs to abiotic stress. Therefore, the aim of this thesis research was to examine the physiological and genomic responses of reproductive tissues to …

Physiological consequences of exposure to heat stress and the mycotoxin zearalenone
… such, it can reduce productivity by disrupting reproductive processes. Although these topics are disparate, the overarching goal of this work is to improve agricultural animal productivity during periods of heat stress. Overall, the three objectives of this thesis were to: 1) isolate the …

Characterization and Role of Secretogranin-II/Secretoneurin in Zebrafish Reproduction
… that have been implicated in the control of reproductive processes. I also observed that secretogranin-II knockout disrupts normal morphology of the pectoral fins by reducing the number of breeding tubercule rows, breeding tubercule width and breeding tubercule cluster length which could …

Reproduction and larval biology of North Atlantic asteroids related to the invasion of the deep sea
… are observed in nature. With few exceptions, the reproductive mechanisms and patterns found in deep-water echinoderms are entirely similar to those found in shallow-water species. The aims of this study were 1) to examine the reproductive biology of the many deep-sea asteroids found on the …
