  Biological interaction - Wikipedia, the free encyclopedia
Biological interactions result from the fact that organisms in an ecosystem interact with each other, in the natural world, no organism is an autonomous entity isolated from its surroundings.
An organism's interactions with its environment are fundamental to the survival of that organism and the functioning of the ecosystem as a whole.
In ecology, biological interactions are the relationships between two species in an ecosystem.

Biological evolution is gene-based (i.e., genes are the primary replicators).
Because this second gene does not interact in the relevant sense with its environment, it is not part of the cause of this increase in frequency.
Replication and variation in the absence of environmental interaction results in drift, and as important as drift may be in the evolutionary process, it is not a consequence of selection (Donoghue 1990).

Biological interaction is the interaction between fish stocks, and within fish stocks, caused by predation and food competition.
When the interaction parameters are positive (c1 > 0 and c2 > 0) we can interpret the two-species model as a predator/prey system since the interaction term c1*f2 produces a higher yield of the prey species when effort on the predator is increased, i.e.

In contrast to biological sequence databases, for which uses and applications are well established, the development of databases and associated tools for organizing, mining and analyzing molecular systems has begun relatively recently.
Investigations of biologically directed questions, such as finding transcription factors putatively linked downstream of known receptor proteins, could be used in generating hypotheses regarding new molecular functions or modes of gene regulation [8,18,19].
The integration of interaction data from various data sources is critical for improving the accuracy of these data [38-42].

Following the discovery that degree distribution in biological networks is typically well approximated by scale free distribution, researchers started to look for other network measurements that would be more powerful in discriminating between various types of networks.
In fact, biological motifs as basic and ubiquitous as futile cycles have been shown not only to be capable of exhibiting characteristic behaviors qualitatively different from those expected classically (under CCK) at high molecular counts, but possibly of offering new functional modalities to any biological network they are imbedded in (4).

This is especially useful for revealing temporal variations in high frequency variance and the physical/biological interactions that occur at these frequencies.
It is apparent that the onset, and ongoing development, of water-column stratification initiates an evolution from a regime dominated by horizontal advection, within which phytoplankton act as a passive tracer, to one where physical processes impact the biology on spatial and temporal scales which are consonant with phytoplankton physiology.
The observed interactions include: 1) transport of distinct bio-optical properties within advected mesoscale features; 2) significant phytoplankton patchiness associated with the regional evolution of the spring bloom and; 3) high frequency bio-optical variability associated with the interaction of the deep chlorophyll maximum with internal wave motions.

To understand these biological effects, we have been studying the interaction of low frequency EM fields with cells at both the cellular and molecular levels.
We have also investigated the mechanism of EM field interactions at the molecular level through effects on three reactions, electron transfer in cytochrome oxidase, ATP hydrolysis by the Na,K-ATPase, and the Belousov-Zhabotinski (BZ) reaction (the catalyzed oxidation of malonic acid).
These properties are consistent with the idea that EM fields affect many biological systems by interacting with electrons moving during redox reactions and also within DNA.

Large-scale studies have revealed networks of various biological interaction types, such as protein-protein interaction, genetic interaction, transcriptional regulation, sequence homology, and expression correlation.
Recurring patterns of interconnection, or 'network motifs', have revealed biological insights for networks containing either one or two types of interaction.
To study more complex relationships involving multiple biological interaction types, we assembled an integrated Saccharomyces cerevisiae network in which nodes represent genes (or their protein products) and differently colored links represent the aforementioned five biological interaction types.
