Summary
Animal signals can be advantageous even when information is public, not private. Signalling can increase information transmission efficiency, benefiting both signalers and receivers.
Area of Science:
- Evolutionary biology
- Animal communication
- Behavioral ecology
Background:
- Animal signals are often assumed to convey private or cryptic information.
- This study challenges the assumption that signals must be private to be advantageous.
Purpose of the Study:
- To propose and formalize a scenario where signalling public information provides an advantage.
- To investigate the conditions under which signalling of public information is favored by natural selection.
Main Methods:
- A game-theoretic model was developed to simulate parent-offspring interactions.
- The model analyzed a parent's decision to invest in one of two offspring based on signals and public cues.
- Offspring signal their condition to influence parental investment.
Main Results:
- Signalling can be favored when it transmits information about offspring quality more efficiently than public cues.
- This occurs even if the information is not private, as signalling enhances transmission efficiency.
- Low-cost signalling can be favored by selection under these conditions.
Conclusions:
- The functional role of animal signals may be broader than previously understood.
- Efficiency benefits can explain the evolution of signalling in various biological and economic contexts.
- Public information signalling can be an evolutionarily stable strategy.

Types of Signaling Molecules
13.8K
In multicellular organisms, many molecules transmit signals between cells to pass information. These signals vary in complexity and include small peptides, nucleotides, steroids, fatty acid derivatives, and dissolved gases such as nitric oxide. Some signaling molecules diffuse through the plasma membrane to act locally between neighboring cells or travel long distances. Others remain attached to the cell surface, transmitting information to other cells only when they make contact. In some...

Sympathetic Signaling
2.7K
Sympathetic signaling, a vital part of the autonomic nervous system, plays a crucial role in mobilizing the body's resources in response to stress or emergencies. It involves the transmission of nerve impulses from sympathetic preganglionic fibers to postganglionic fibers. This results in the release of specific neurotransmitters and activation of adrenergic receptors.
Sympathetic preganglionic fibers release the neurotransmitter acetylcholine (ACh) onto the ganglionic neurons in the...

Bacterial Signaling
42.4K
Bacterial signaling can occur within bacteria (intracellular) or between bacteria (intercellular). At times, a group of bacteria behaves like a community. To achieve this, they engage in quorum sensing, the perception of higher cell density that causes changes in gene expression. Quorum sensing involves both extracellular and intracellular signaling. The signaling cascade starts with a molecule called an autoinducer (AI). Individual bacteria produce AIs that move out of the bacterial cell...

What is Cell Signaling?
131.9K
Despite the protective membrane that separates a cell from the environment, cells need the ability to detect and respond to environmental changes. Additionally, cells often need to communicate with one another. Unicellular and multicellular organisms use a variety of cell signaling mechanisms to communicate to respond to the environment.

Hedgehog Signaling Pathway
10.3K
The Hedgehog gene (Hh) was first discovered due to its control of the growth of disorganized, hair-like bristles phenotype in Drosophila, much like hedgehog spines. Hh plays a crucial role in the development of organs and the maintenance of homeostasis in both invertebrates and vertebrates. However, while Drosophila has only one Hh protein, mammals have multiple functional Hedgehog proteins - Sonic (Shh), Desert (Dhh), and Indian Hedgehog (Ihh). All of these homologous proteins have adapted to...

Interactions Between Signaling Pathways
7.6K
Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...
