Lizard threat display handicaps endurance.
Honest-signalling theory asserts that threat displays reliably advertise attributes that influence fighting success. Endurance, as measured by treadmill performance, predicts the outcome of agonistic interactions among lizards. If threat displays in lizards function to advertise endurance capacity then variation in threat displays should correlate with endurance. I tested this prediction for th...
متن کاملThermal dependence of endurance and locomotory energetics in a lizard.
The thermal dependencies of endurance and the rates of oxygen cnsumption (VO2) and carbon dioxide production (VCO2) were determined for the lizard Dipsosaurus dorsalis walking on a treadmill. The thermal dependencies of endurance and maximal VO2 (VO2 max) are nerly identical. The maximal sustainable speed and the speed at which VO2 max is attained at each experimental body temperature are the s...
متن کاملPhage display for detection of biological threat agents.
The essential element of any immuno-based detector device is the probe that binds analyte and, as a part of the analytical platform, generates a measurable signal. The present review summarizes the state of the art in development of the probes for detection of the biological threat agents: toxins, bacteria, spores and viruses. Traditionally, the probes are antibodies, which are isolated from se...
متن کاملAssociated Handicaps in Cerebral Palsy
Cerebral palsy (CP) is one of the most common disabilities affecting children. Most of the children suffering from cerebral palsy have associated abnormalities, which have a direct effect upon rehabilitation management, functional outcome and prognosis. Two hundred diagnosed cases of CP in the age group of two years and above were assessed and various associated handicaps were identified. In th...
متن کاملLaboratory endurance capacity predicts variation in field locomotor behaviour among lizard species.
I measured locomotor endurance capacities of lizards on a motorized treadmill in the laboratory and compared average values for different species with quantitative measures of their movement in the field (percentage of time moving, N=15 species; moves/min, N=13; daily movement distance, N=11). I hypothesized that endurance would be positively related to all three movement indices. Relationships...
