Stereological Determination of Tracheal Volume and Diffusing Capacity of the Tracheal Walls in the Stick Insect Carausius morosus (Phasmatodea, Lonchodidae)
First instars of Carausius morosus provide a good model for morphometric evaluation of the diffusing capacity between the tracheal system and hemolymph: air sacs are lacking, tracheoles do notExpand

Evolution of air breathing: oxygen homeostasis and the transitions from water to land and sky.
Life originated in anoxia, but many organisms came to depend upon oxygen for survival, independently evolving diverse respiratory systems for acquiring oxygen from the environment. Ambient oxygenExpand

Physiological and psychological performance of Taekwondo Athletes is more affected by rapid than by gradual weight reduction
Background The results of previous studies regarding the impact of different forms of weight reduction on performance capacity are not consistent. Therefore, the purpose of this study was theExpand

The analysis of the mechanosensory origin of the infrared sensilla in Melanophila acuminata (Coeloptera; Buprestidae) adduces new insight into the transduction mechanism.
The thoracic infrared (IR) sensilla of the pyrophilous jewel beetle Melanophila acuminata most likely have evolved from hair mechanoreceptors (sensilla trichodea). To further elucidate the sensoryExpand

Respiratory system of arachnids I: morphology of the respiratory system of Salticus scenicus and Euophrys lanigera (Arachnida, Araneae, Salticidae).
The book-lungs and the tracheal systems of two species of jumping spider, Salticus scenicus and Euophrys lanigera, were investigated using gross anatomical, light and electron microscopic methods.Expand

Coping with cyclic oxygen availability: evolutionary aspects.
Both the gradual rise in atmospheric oxygen over the Proterozoic Eon as well as episodic fluctuations in oxygen over several million-year time spans during the Phanerozoic Era, have arguably exertedExpand

Bimodal breathing in jumping spiders: morphometric partitioning of the lungs and tracheae in Salticus scenicus (Arachnida, Araneae, Salticidae).
In jumping spiders, both the book lungs and the tracheal system are well-developed. The tracheal system consists of four thick primary tracheae that branch into small secondary tracheae, some of themExpand

Morphology of a thermosensitive multipolar neuron in the infrared organ of Merimna atrata (Coleoptera, Buprestidae).
Two pairs of infrared (IR) organs are situated ventrolaterally on the second and third abdominal sternites of the Australian fire beetle Merimna atrata (Buprestidae). In ventral view, each IR organExpand

Hypoxic tolerance in air-breathing invertebrates
Terrestrial invertebrates experience hypoxia in many habitats and under a variety of physiological conditions. Some groups (at least insects) are much more capable of recovery from anoxia than mostExpand
