The Evolution of Sex Determination and the DMRT1 Gene in the Japanese Gecko (Gekko japonicus)
… was observed during embryonic development in geckos with a TSD mechanism. To do this, I observed the rate of transcription of the <em>Dmrt1</em> gene in the Gecko species <em>Gekko japonicus</em>. Pregnant geckos were caught around Nanjing, China. Once the females laid their eggs, the eggs …

Comparative approaches to otoacoustic emissions : towards and understanding of why the ear emits sound
… in humans and an array of non-mammals (chickens, geckos and frogs) who lack these mammalian features and exhibit a diverse range of morphologies.

Structure and social significance of vocalization by Anolis grahami grahami (Sauria: Iguanidae)
… the lizard suborder, only the sounds of geckos (Gekkonidae) have been closely studied. The purposes of this study were to describe the physical structure, social significance, and means of sound production by Anolis g. grahami, one of the 13 anoline species known to vocalize. Recordings …

Biologically inspired attitude control of robotic systems using center of gravity reallocation
… forces for their orientation control. Lizards, geckos and arboreal animals effectively use their inertial appendages to control their attitude dynamics. On the other hand, flying species such as biological bats employ their relatively heavier wings to produce inertial forces during their flight. …

Biomimetic adhesion for transfer printing via microstructured surfaces
… adhesion techniques employed by animals such as geckos and insects has inspired a field of research into the use of dispersive intermolecular forces as an engineering solution for limitations of nanofabrication and assembly. In the following chapters I will describe our own group’s design, …

A Model of the Production of Spontaneous Otoacoustic Emissions in the Tokay Gecko
… of amplitudes and frequencies into the ears of geckos we have observed novel behaviors previously predicted by our model. We conclude that interactions along the basilar papilla, mediated by elastic elements, play an important role in the formation of spontaneous otoacoustic emissions.</p>

An experimental study on adhesive or antiadhesiveand strong bio-inspired nanomaterials
… 150 years. However, certain phenomena about geckos are still not completely understood and nowadays these still represent the main challenge of several scientific discussions which aim to better understand the gecko’s adhesive ability. This thesis deals first with the influence of surface …

Nocturnal Flights of TRIATOMA (Hemiptera: Reduviidae) in Sabino Canyon, Arizona
… on sticky traps. Desert tortoises. banded geckos and scorpions were found in Neotoma lodges.</p> <p>Triatoma rubida uhleri bugs overwinter as 5th instar nymphs. As soon as average temperatures warm up to 23° to 25°C, the 5th instar nymphs begin molting to adults. This produces large numbers …
