Intraspecific variation in tracheal volume in the American locust, Schistocerca americana, measured by a new inert gas method
SUMMARY The volume of a tracheal system influences breath-holding capacity and provides an index of an insect's investment in its respiratory system. Here, we describe a new, generally applicableExpand

Lipid content of terrestrial arthropods in relation to body size, phylogeny, ontogeny and sex
Energy storage in arthropods has important implications for survival and reproduction. The lipid content of 276 species of adult arthropods with wet mass in the range 0.2–6.13 g is determined toExpand

Exoskeletal chitin scales isometrically with body size in terrestrial insects
The skeletal system of animals provides the support for a variety of activities and functions. For animals such as mammals, which have endoskeletons, research has shown that skeletal investmentExpand

Body size is not critical for critical PO2 in scarabaeid and tenebrionid beetles
SUMMARY Constraints on oxygen delivery potentially limit animal body size. Because diffusion rates are highly distance dependent, and because tracheal length increases with size, gas exchange wasExpand

A tale of two species: Extirpation and range expansion during the late Quaternary in an extreme environment
Abstract Death Valley, California is today the hottest hyperarid area in the western Hemisphere with temperatures of 57 °C (134 °F) recorded. During the late Quaternary, pluvial Lake Manly coveredExpand

Structural changes in gills of Lost River suckers exposed to elevated pH and ammonia concentrations.
The Lost River sucker (Deltistes luxatus) is a federally listed, endangered fish that occurs primarily in Upper Klamath Lake-a hypereutrophic lake in southern Oregon, USA. A decline of the suckerExpand

The use of tunable diode laser absorption spectroscopy for rapid measurements of the delta13C of animal breath for physiological and ecological studies.
In this study we introduce the use of tunable diode laser absorption spectroscopy (TDLAS) as a technique for making measurements of the delta13C of animal 'breath' in near real time. The carbonExpand

Survival of Lost River Suckers (Deltistes luxatus) Challenged with Flavobacterium columnare During Exposure to Sublethal Ammonia Concentrations at pH 9.5
The Lost River sucker (Deltistes luxatus) is a federally listed, endangered species inhabiting the hypereutrophic waters of Upper Klamath Lake in southern Oregon, USA. High pH (≥10) and elevatedExpand

Life in an extreme environment: a historical perspective on the influence of temperature on the ecology and evolution of woodrats
Abstract The heterogeneous topography of the Great Basin province leads to one of the most climatically variable regions in the Northern Hemisphere. Along the southwestern edge lies Death Valley, anExpand
