Introduced species and their missing parasites
TLDR
This poster presents a probabilistic procedure to estimate the planktonic distribution of infectious coronavirus in the North Pacific Ocean using avessels as a model for the response of these animals to infectious disease.
Energy limitation as a selective pressure on the evolution of sensory systems
TLDR
Assessing evidence from a wide range of vertebrate and invertebrate examples, it is shown that reducing energy expenditure can account for many of the morphological features of sensory systems and has played a key role in their evolution.
Why Do Axons Differ in Caliber?
TLDR
Information rate may be the main variable that sets axon caliber, with axons constrained to deliver information at the lowest acceptable rate, given constraints on space and energy.
Action Potential Energy Efficiency Varies Among Neuron Types in Vertebrates and Invertebrates
TLDR
In the single compartment models studied here, AP energy consumption varies greatly among vertebrate and invertebrate neurons, with several mammalian neuron models using close to the capacitive minimum of energy needed.
Are Bigger Brains Better?
Conserved Regulation of Cardiac Calcium Uptake by Peptides Encoded in Small Open Reading Frames
TLDR
Two smORF-encoded peptides of less than 30 amino acids regulating calcium transport and, hence, regular heart contraction, in the fruit fly Drosophila heart are described, suggesting that the mechanisms for heart regulation are ancient and that smORFs may be a fundamental genome component that should be studied systematically.
Fly Photoreceptors Demonstrate Energy-Information Trade-Offs in Neural Coding
TLDR
The fixed cost, the total cost of signalling, and the unit cost all increase with a photoreceptor's highest information rate to make information more expensive in higher performance cells, promoting the evolution of economical structures by severely penalising overcapacity.
Do insect metabolic rates at rest and during flight scale with body mass?
TLDR
It is argued that low FMR in small insects suggests these insects may be making considerable energy savings during flight, which could be extremely important for the physiology and evolution of insect flight.
Balanced Excitatory and Inhibitory Synaptic Currents Promote Efficient Coding and Metabolic Efficiency
TLDR
By producing fewer, more informative spikes approximately balanced synaptic currents in cortical neurons can promote both coding efficiency and energy efficiency, and also be more energy efficient than other synaptic regimes.
