The theory integrates aspects of biology, ecology, and physiology to provide a comprehensive model for understanding growth, reproduction, and aging in organisms. ### Key Features of DEB Theory: 1. **Energy Allocation**: DEB theory posits that an organism allocates its energy to various life processes, including maintenance, growth, reproduction, and storage.
Dynamical neuroscience is a subfield of neuroscience that focuses on understanding the complex, dynamic behaviors of neural systems over time. It combines principles from various disciplines, including neuroscience, physics, mathematics, and engineering, to study how biological networks of neurons, synapses, and other components interact and evolve in response to internal and external stimuli.
The term "ecosystem model" refers to a representation of the complex interactions and relationships within an ecosystem. These models can be used to simulate, analyze, and predict how ecosystems function, respond to various stresses, and change over time. Ecosystem models can vary in complexity, scope, and purpose, and they often incorporate various elements such as: 1. **Biotic Components**: These are the living organisms within an ecosystem, including plants, animals, fungi, and microorganisms.
The elasticity coefficient is a measure used in economics to quantify the responsiveness of one variable to changes in another variable. It indicates how much one variable will change when a corresponding change occurs in another variable. There are several types of elasticity coefficients, but they are often used in the context of price elasticity of demand and supply. Here are some common forms: 1. **Price Elasticity of Demand (PED)**: This measures how much the quantity demanded of a good responds to a change in its price.
Elementary modes are a concept from systems biology and metabolic engineering, particularly related to the analysis of metabolic networks. They provide a way to understand the possible metabolic behaviors of a system under given constraints. In more detail, an elementary mode is defined as a feasible pathway through a metabolic network that operates under certain conditions, typically consisting of a set of enzymes that can generate a specific product while satisfying the network's stoichiometric constraints.
The Fixation Index, commonly referred to as FST, is a measure used in population genetics to quantify the degree of genetic differentiation between populations. Specifically, it reflects the proportion of genetic variance that can be attributed to differences between populations compared to the total genetic variance within and among those populations. FST values range from 0 to 1: - An FST of 0 indicates that there is no genetic differentiation between populations, suggesting that they are genetically identical or very similar.
FlowJo is a software application used for the analysis of flow cytometry data. Flow cytometry is a technique that allows for the measurement of physical and chemical characteristics of cells or particles in suspension.

Folding@home is a distributed computing project aimed at understanding protein folding, misfolding, and related diseases, such as Alzheimer's, Parkinson's, and various cancers. Launched in October 2000 by Stanford University, the project allows volunteers to contribute their computer's processing power to help simulate the physical movements of atoms in proteins. Participants can download software that runs simulations on their own computers, and the collected data is used to model how proteins fold and misfold.
The Free Energy Principle (FEP) is a theoretical framework that seeks to explain how biological systems maintain their organization and functionality in the face of an uncertain and changing environment. It is rooted in principles from thermodynamics, information theory, and neuroscience. The core idea of the FEP is that living systems strive to minimize their free energy, which can be understood as a measure of surprise or uncertainty. At its most basic level, the FEP posits that organisms engage in a form of active inference.
GeneMark is a software tool used for gene prediction in prokaryotic and eukaryotic genomes. Developed by the bioinformatics researcher Mark Borodovsky and his colleagues, GeneMark utilizes statistical models to identify potential genes based on sequences in the genome. The software employs methods such as Hidden Markov Models (HMMs) and language-like models to differentiate coding regions (genes) from non-coding regions based on sequence characteristics.
Gene prediction refers to the process of identifying the locations of genes within a genome. This involves determining the sequences of DNA that correspond to functional genes, as well as predicting their structures, including coding regions (exons), non-coding regions (introns), regulatory sequences, and other features that are essential for gene function and expression.
Haldane's dilemma is a concept in evolutionary biology proposed by the British geneticist J.B.S. Haldane in the early 20th century. It addresses the genetic implications of natural selection, specifically regarding the limits of adaptation in populations. The key idea behind Haldane's dilemma is that for a population to evolve beneficial traits through natural selection, there are finite limits to how quickly these traits can spread through the population based on genetic changes.
Hypercyclic morphogenesis is a concept in the field of developmental biology that pertains to the processes and mechanisms through which complex structures and forms develop in biological organisms. The term "hypercyclic" often refers to the idea of cycles of growth and differentiation that can occur at multiple scales, potentially leading to intricate patterns and forms seen in living organisms. In a broader sense, morphogenesis itself is the biological process that causes an organism to develop its shape.
The Infinite Alleles Model (IAM) is a concept in population genetics that describes the genetic variation within a population. It assumes that a gene locus can have an infinite number of possible alleles. According to this model, every mutation creates a new allele that has never been seen before in the population, thus leading to an ever-expanding pool of genetic diversity.
The Infinite Sites Model is a concept used in population genetics, particularly in the context of genetic mutation and variation. In this model, it is assumed that there are an infinite number of possible genetic loci (sites) that can mutate. Each locus can mutate independently, and each mutation is considered to create a new, unique genetic variant. This means that over time, as mutations accumulate, the genetic diversity in a population can increase without limit, due to the assumption of infinite sites.
Integrodifference equations are a type of mathematical equation used to model discrete-time processes where dynamics are influenced by both local and non-local (or distant) interactions. These equations are particularly useful in various fields such as population dynamics, ecology, and spatial modeling where the future state of a system depends not only on its current state but also on the states of neighboring systems or regions.
