Abstract 1. 1. The respiratory rate of isolated brains from 36 different species of insects, belonging to 6 separate orders, was determined in order to ascertain whether or not poikilotherms exhibit an inverse relationship between respiratory rate and weight of the organ or whole body. 2. 2. Index of cephalization, i.e. the ratio between brain and body weight, was found to decrease with increasing body size. Specific metabolic rate (SMR) (oxygen consumption/mg dry weight/hr) of the brain… Expand
The Allometry of Brain Miniaturization in Ants
TLDR
The comparative and intraspecific studies show the extent to which nervous systems can be miniaturized in taxa exhibiting behavior that is apparently comparable to that of larger species or individuals. Expand
On Being Small: Brain Allometry in Ants
TLDR
It is shown that ants have considerably smaller brains than any ant-sized vertebrate would have, and that this result holds even if the relatively higher exoskeleton weights of ants (as compared to endoskeleton weight of mammals) are taken into account. Expand
The allometry of the central nervous system during the postembryonic development of the spider Eratigena atrica.
TLDR
In postembryonic development, the share of the subesophageal ganglion and neuropil in the total volume of the CNS increased, whereas that of the brain and cortex decreased, which is similar to that observed in other arthropods. Expand
Endothermy of organisms and subcellular mechanisms of thermogenesis
It is generally known that mammals and birds are warm-blooded, and they are able to maintain such a state is not only in comfort, but in low and high temperature conditions. These circumstances, inExpand
Utilization of glucose and proline in the brain of adult insects
TLDR
It is found that 14CO2 production from labelled glucose and proline in brains of insects seems to be correlated with the metabolic rate of these organs. Expand
Worker senescence and the sociobiology of aging in ants
TLDR
It is concluded that an innovative fusion of sociobiology, senescence theory, and mechanistic studies of aging can improve the understanding of the adaptive nature of worker life span in ants. Expand
Brain Aging in Insects
TLDR
In insects the crucial role of the CNS in developmental processes is well established; however, it is an open question whether the brain also governs the aging processes. Expand
The Natural Science Underlying Big History

TLDR
No new science is needed to describe cosmic evolution's major milestones at a deep and empirical level; Quantitative models and experimental tests imply that a remarkable simplicity underlies the emergence and growth of complexity for a wide spectrum of known and diverse systems. Expand
A Singular Universe of Many Singularities: Cultural Evolution in a Cosmic Context
Nature’s myriad complex systems—whether physical, biological or cultural—are mere islands of organization within increasingly disordered seas of surrounding chaos. Energy is a principal driver of theExpand
Energy-Efficient Coding with Discrete Stochastic Events
TLDR
It is concluded that when energy use is a significant constraint, trade-offs between information transfer and energy can strongly influence the number of signaling molecules and synapses used by neurons and the manner in which these mechanisms represent information. Expand

OXYGEN CONSUMPTION OF MOTHS DURING REST, PRE-FLIGHT WARM-UP, AND FLIGHT IN RELATION TO BODY SIZE AND WING MORPHOLOGY
TLDR
The sphingids had higher wing loading, aspect ratio, and wing beat frequency during flight than the saturniids, and the scaling of oxygen consumption during flight in the moths is almost identical to that of bats and birds. Expand
Metabolic rates related to muscle activity in bumblebees.
TLDR
Oxygen consumption, thoracic temperature, and action potentials from the fibrillar muscles were concurrently recorded in queens and workers of Bombus vosnesenskii and the results are compared with those from other insects and their adaptive significance is discussed. Expand

TLDR
The absolute level of Q O 2 in the new media (which apart from glucose contain pyruvate, fumarate and L-glutamate) was higher than the values reported in the literature for saline media and of the same order as the highest values recorded for serum. Expand
ENERGY METABOLISM OF DRAGONFLIES (ODONATA: ANISOPTERA) AT REST AND DURING ENDOTHERMIC WARM-UP
1. 1. Energy metabolism at rest and during pre-flight warm-up was measured in a variety of anisopterous dragonflies. 2. 2. Resting oxygen consumption was similar in its relation to body temperatureExpand

TLDR
This study shows that the 0.75 interspecific mass exponent in Kleiber's equation is a statistical artifact and suggests that the data from literature are consistent with the theory of biological similitude of Lambert and Teissier. Expand
Respiration in Drosophila. II. Respiration in relation to age by wild, inbred and hybrid Drosophila melanogaster imagos.
TLDR
When the data relating to the three populations studied are pooled together there exist no relation between the mean respiration rates and the other quantitative traits measured and particularly between the decreases in respiration rate and fecundity with age. Expand
Carbohydrate and fat metabolism in adult lepidoptera.
TLDR
The biological importance of the specialisation of carbohydrate metabolism in adult Lepidoptera is evident, as fat is used partly to form the egg-yolk, and therefore carbohydrate nutrition is directly connected with fertility. Expand
Respiration of Phormia regina in relation to temperature and oxygen
TLDR
Respiratory rates of larvae, pupae, and adults of Phormia regina in general follow a sigmoid curve with respect to temperatures from 0 to 45°C, but there is an unexplained plateau between 10 and 15° in the curve for intact larvae. Expand
The influence of age and diet on respiration in adult male and female blowflies, Phormia regina.
TLDR
Female Phormia regina were found to utilize more oxygen than males especially after approximately the sixth day of adulthood on both a μl/specimen andμl/mg basis. Expand
