A sexually dimorphic circuit switch in higher olfactory centres
A sexually dimorphic circuit switch in higher olfactory centres In Drosophila the male sex pheromone cis-vaccenyl acetate (cVA) elicits different behaviours in males and females: while males are repelled by cVA, it stimulates female receptivity. However, olfactory receptor neurons and their …

Sexually Dimorphic Developmental Patterns of Chemosensory Behaviors in African Elephants (Loxodonta Africana)
Like many polygynous mammals, African elephants exhibit social dimorphism in which females reside in matriarchal groups while males often travel alone or in bachelor groups. Males search for receptive mates who may advertise their condition through chemical and other signals. The difference in …

Control of Sexually Dimorphic Brain Pathway Development in Cultured Zebra Finch Brain Slices
In zebra finches (Taeniopygia guttata), males sing but not females. Previous studies showed singing requires the formation of a male-specific projection from nucleus HVC (higher vocal center, in the neostriatum) to nucleus RA (robust nucleus of the archistriatum). Fibers from HVC first enter the …

The genetics of the sexually dimorphic deaths of the C. elegans CEM neutrons
The cells of metazoan organisms possess the capability to commit a form of cellular suicide known as programmed cell death or apoptosis. The proper control of this endogenous death program is essential to animal development and to the prevention of disease. To better understand how individual cells …

The impact of NOX4 deficiency on sexually dimorphic lipid handling in HFD-challenged mice
Dietary excess promotes metabolic dysfunction through nutrient overload. If sustained, it can impair physiological metabolic processes necessary for the proper handling of nutrients. Proper handling of nutrients depends on the capacity of an organism to properly sense, regulate, respond, and adapt …

MET-2 and SET-25 have sexually dimorphic effects on chromosome structure in Caenorhabditis elegans
Meiosis is a highly conserved cellular division, which allows for the formation of haploid gametes. During meiosis chromosomes undergo two successive segregation events. Homologous chromosomes segregate in meiosis I and the sister chromatids subsequently segregate in meiosis II, leading to the …

Comparative analysis of gene expression in two sexually dimorphic crustacean species Euphilomedes carcharodonta and Euphilomedes morini
… important in the development and function of the sexually dimorphic lateral eye. E. carcharodonta and E. morini show similar gene expression patterns suggesting that these patterns have been conserved over evolutionary time to produce the observed dimorphic morphology.</p>

Investigating the role of neuroendocrine signaling in the regulation of sexually dimorphic behavior of C. elegans
… for more subtle differences in the regulation of sexually dimorphic behaviors. Chapter One of this thesis discusses sexual dimorphisms in the nervous systems and behaviors of several species, with particular focus on work in the nematode, Caenorhabditis elegans. In Chapter Two, we show that sexual …

A phylogeny of the genus Gasteracantha Sundevall, 1833 (Araneae, Araneidae) with an examination of sexually dimorphic characters in the subfamily Gasteracanthinae
… with an examination of the evolution of several sexually dimorphic characters. Finally, taxonomic changes are proposed, suggestions around improving molecular and morphological work along with future areas of ecological study are made, and a novel approach to gathering images for future …

Effects of Gestational and Lactational Exposure to 2,3,7,8-Tetrachlorodibenzo-P-Dioxin or Coplanar PCBs on Reproductive Development and Sexually Dimorphic Behaviors in Rats
In contrast sexually dimorphic non-reproductive behaviors were affected in TCDD and coplanar PCB exposed rats. In the initial study, the play behavior in TCDD exposed rats was suppressed. However in the follow-up study, when play behavior was tested with a different protocol than in the initial …

Investigating the neurobiological basis underlying the sex-specific production of courtship song in Drosophila: the roles of sex determination genes fruitless and doublesex
… However, the critical differences underlying the sexually dimorphic production of courtship song are unknown; moreover, the relative contributions of fru and dsx to the generation of these differences are not known. The central aim of this thesis was to investigate the neurobiological basis for …

Evolution of a Novel Neuronal Sex-Specifically Spliced Gene in Mosquitoes
… the mechanisms that generate these important sexually dimorphic behaviors in mosquitoes is a crucial step towards developing strategies to combat vector borne disease spread. In this work, we investigate the molecular mechanisms of sexually dimorphic behaviors in mosquitoes by characterizing a …

Variation in Non-Metric Traits of the Pelvis Between Whites, Blacks, and Hispanics

However, it has been suggested that the male pelvis may exhibit more variation then the female pelvis and that sexually dimorphic nonmetric traits change …

Impacts of Placental Growth Factor Deficiency and of Preeclampsia on Brain Development and Function
