The Sense of Self: Reflected Self-Appraisal and Social Comparison02:57

The Sense of Self: Reflected Self-Appraisal and Social Comparison

56.9K
According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...

Population Growth

29.6K
Population size is dynamic, increasing with birth rates and immigration, and decreasing with death rates and emigration. In ideal conditions with unlimited resources, populations can increase exponentially, which plots as a J-shaped growth rate curve of population size against time. This type of curve is characteristic of newly-introduced invasive species, or populations that have suffered catastrophic declines and are rebounding.

The Colonization of Land02:22

The Colonization of Land

38.8K
Changes in the environment of the early Earth drove the evolution of organisms. As prokaryotic organisms in the oceans began to photosynthesize, they produced oxygen. Eventually, oxygen saturated the oceans and entered the air, resulting in an increase in atmospheric oxygen concentration, known as the oxygen revolution approximately 2.3 billion years ago. Therefore, organisms that could use oxygen for cellular respiration had an advantage. More than 1.5 years ago, eukaryotic cells and...

Social Traps01:41

Social Traps

27.1K
Social traps are negative situations where people get caught in a direction or relationship that later proves to be unpleasant, with no easy way to back out of or avoid. The concept was orignally introduced by John Platt who applied psychology to Garrett Hardin's "Tragedy of the Commons", where in New England herd owners could let their cattle graze in the common ground. This situation seems like a good idea, but an individual could have an advantage. If they owned...

Levels of Use of a GIS01:29

Levels of Use of a GIS

470
Geographic Information Systems (GIS) operate across three levels of application, each representing an increasing degree of complexity: data management, analysis, and prediction. These levels reflect the expanding functionality and versatility of GIS technology in handling spatial data for diverse purposes.Data ManagementAt its foundational level, GIS serves as a tool for data management, enabling the input, storage, retrieval, and organization of spatial data. This level is often employed in...

Data Collection by Observations01:08

Data Collection by Observations

15.7K
Data collection refers to a systematic way of obtaining, observing, measuring, and analyzing accurate information. Observational studies are one of the most widely used methods of data collection. It involves collecting data by observing the behavior and physical characteristics of a sample without making any modifications to the sample.
An astronomer viewing the motion and brightness of stars in the sky and recording the data is an example of observational data collection. A botanist recording...

Summary

Colonial animals use social information from group members to make better decisions about survival and reproduction. This information sharing is crucial for the evolution, formation, and maintenance of animal colonies.

Area of Science:

  • Ecology
  • Evolutionary Biology
  • Animal Behavior

Background:

  • Colonial living in animals is common, but the underlying ecological and evolutionary drivers are not fully understood.
  • Recent research highlights the role of social information within animal groups.
  • Social information influences critical decisions related to survival and reproduction.

Purpose of the Study:

  • To review the types of social information available in colonial animals.
  • To examine how social information enhances decision-making within colonies.
  • To discuss the role of information in the evolution, formation, and maintenance of colonies.

Main Methods:

  • Literature review of studies on social information in colonial animals.
  • Analysis of decision-making processes enhanced by social information.
  • Synthesis of information use across various aspects of colonial life.

Main Results:

  • Colonial animals provide and utilize diverse types of social information.
  • Social information improves decisions regarding predator avoidance, resource acquisition, and reproduction.
  • Information use is integral to the development and persistence of colonies.

Conclusions:

  • Social information is a key factor in understanding coloniality.
  • The exchange of information shapes the evolution and maintenance of social groups.
  • Information use is a pervasive element in all facets of colonial animal life.
