In general, tinamous prefer running to flying and only take off when pressed for it After the challenge both species of tinamous appeared unequivocally exhausted and displayed fast gular fluttering, but not Red Junglefowl or bantam chickens. The aerobic challenge test was used in three procedures carried out separately: 1 blood lactate determination, 2 oxygen consumption measurements and 3 body temperature monitoring. Blood lactate was measured before and immediately after the challenge test taking a small blood sample from an ulnar vein punction.
The blood sample was processed for immediate determination of lactate concentration using a portable analyser Lactate-Pro, Arkray Inc, Kyoto, Japan. The lactate analyser has been previously validated for use with bird blood Oxygen consumption was measured by open respirometry in a push-mode configuration before and immediately after the aerobic challenge test previously described. To account for the effect of circadian rhythms all measurements were carried out between All results are presented as average with standard deviations s.
Statistical analysis was carried out using general linear models followed by posthoc Tukey tests Minitab v. Permutation tests are adequate and more robust than parametric tests to compare differences between groups Power regression analysis on cardiac growth for the different species was carried out after double logarithm transformation and Model II regression analysis orthogonal regression in Minitab v. Model II regression was preferred over Model I regression because both variables body mass and ventricular mass are obtained experimentally and include random measurement error Publisher's note: Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations.

Discussion The tinamou heart can generate pressure but not flow Our results confirm that the heart of tinamous is the smallest among all extant bird species 11 , The cardiac morphology and physiology of the tinamous limits aerobic performance Ventricular size and its flow-limited capability have no effect on resting metabolism in thermoneutral conditions.

Heart Morphometry Animals were killed by gunshot or euthanized by decapitation. Hematology 0. Statistical Analysis All results are presented as average with standard deviations s.

Invasive Termites. Back Matter Pages About this book Introduction Biology of Termites, a Modern Synthesis brings together the major advances in termite biology, phylogenetics, social evolution and biogeography made in the decade since Abe et al Termites: Evolution, Sociality, Symbioses, Ecology became the standard modern reference work on termite science.
Very strong evolutionary and developmental themes run through the individual chapters, fed by new data streams from molecular sequencing, and for the first time it is possible to compare the social organisation of termites with that of the social Hymenoptera, focusing on caste determination, population genetics, cooperative behaviour, nest hygiene and symbioses with microorganisms. New chapters have been added on termite pheromones, termites as pests of agriculture and on destructive invasive species, and new molecular and cladistic frameworks are presented for clarifying taxonomy, especially in the higher termites which dominate many tropical ecosystems.
Applied entomologists, developmental and evolutionary biologists, microbial ecologists, sociobiologists and tropical agriculture specialists will all benefit from the new insights provided by this work. Caste differentiation Eusociality Microbial symbioses Pest status Termites.
