Flock members experience gas pressures higher than lone individuals
Biosystems. 2024 Mar 16:105192. doi: 10.1016/j.biosystems.2024.105192. Online ahead of print.ABSTRACTLocal interactions between flock members in absence of centralized control generate collective dynamics characterized by coherent large-scale patterns. We investigate whether aggregates of individuals like birds, swarms and fishes behaving in concert with their neighbors may modify the physical properties of the fluid medium in which they are embedded. Using the K-Nearest Neighbours algorithm to simulate collective animal behavior, we showed that the occurrence of collective dynamics can modify the physical parameters of th...

The epoch-making importance of Ervin Bauer's theoretical biology
Biosystems. 2024 Mar 14:105179. doi: 10.1016/j.biosystems.2024.105179. Online ahead of print.ABSTRACTErvin Bauer was the only biologist who recognized that the best way to develop theoretical biology on an equal footing with theoretical physics was to follow the method that has ensured the great successes of modern theoretical physics: the general method of science. Following this method, he succeeded to find the universal principle of biology. From this principle he managed to derive all the basic equations of biology, that of metabolism, reproduction, growth, responsiveness and successfully explained all the fundamental ...

Unraveling power-law scaling through exponential cell division dynamics
Biosystems. 2024 Mar 14:105190. doi: 10.1016/j.biosystems.2024.105190. Online ahead of print.ABSTRACTA primary objective of biology is the development of universal laws that define how organic form develops and how it evolves as a function of size, both ontogenetically and across evolutionary time. Scaling theory has been essential in reaching this goal by giving a complete perspective point, particularly in illuminating the fundamental biological features produced within scaling exponents defining families of equations. Nonetheless, the theoretical basis of the allometric equation within scaling theory are inadequately ex...

Embodied essentialism in the reconstruction of the animal sign in robot animal design
Biosystems. 2024 Mar 13:105178. doi: 10.1016/j.biosystems.2024.105178. Online ahead of print.ABSTRACTRobot animals are important for the interpretation of the biological world. In this paper, I show that specific design solutions for robot animal signs usually privilege the overall perception of biological systems (and animal signs in general) as machinic entities, which ignores the role of identity self-generation and sustainability, the hallmark of biological signs. Animal signs are semiotic systems that operate roughly on three subsystems: affordance mapping (related with niche construction and embeddedness), essence ca...

The pseudoentropy of allele frequency trajectories, the persistence of variation, and the effective population size
Biosystems. 2024 Mar 11:105176. doi: 10.1016/j.biosystems.2024.105176. Online ahead of print.ABSTRACTTo concisely describe how genetic variation, at individual loci or across whole genomes, changes over time, and to follow transitory allelic changes, we introduce a quantity related to entropy, that we term pseudoentropy. This quantity emerges in a diffusion analysis of the mean time a mutation segregates in a population. For a neutral locus with an arbitrary number of alleles, the mean time of segregation is generally proportional to the pseudoentropy of initial allele frequencies. After the initial time point, pseudoentro...

Online ahead of print.ABSTRACTA frequently debated topic related to the origin of life centers around the question of how complex forms of life on today's Earth may have evolved over time from simpler predecessors. For example, the question of how proton concentration gradients across cellular membranes developed in ancestral protocells remains unanswered. This process, which is indispensable for the generation of chemical energy in modern organisms, is driven by energy derived from redox processes in the respiratory chain. Since it is highly unlike...
