Conservation of Small Populations02:04

Conservation of Small Populations

16.7K
Small population sizes put a species at extreme risk of extinction due to a lack of variation, and a consequent decrease in adaptability. This weakens the chances of survival under pressures such as climate change, competition from other species, or new diseases. Large populations are more likely to survive pressures such as these, as such populations are more likely to harbor individuals that have genetic variants that are adaptive under new stresses. Small populations are much less...

What is Population Genetics?

64.6K
A population is composed of members of the same species that simultaneously live and interact in the same area. When individuals in a population breed, they pass down their genes to their offspring. Many of these genes are polymorphic, meaning that they occur in multiple variants. Such variations of a gene are referred to as alleles. The collective set of all the alleles within a population is known as the gene pool.

Population Growth

28.2K
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.

Structures of Solids

17.6K
Solids in which the atoms, ions, or molecules are arranged in a definite repeating pattern are known as crystalline solids. Metals and ionic compounds typically form ordered, crystalline solids. A crystalline solid has a precise melting temperature because each atom or molecule of the same type is held in place with the same forces or energy. Amorphous solids or non-crystalline solids (or, sometimes, glasses) which lack an ordered internal structure and are randomly arranged. Substances that...

Structural Isomerism

Isomerism in Complexes
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can...

Summary
This summary is machine-generated.

Witchcraft accusations in China created social divisions. Labeled "zhu" households avoided cooperation with outsiders, instead forming exclusive internal networks, impacting community cohesion.

Area of Science:

  • Social Anthropology
  • Cultural Sociology
  • Behavioral Economics

Background:

  • Anthropological theories debate witchcraft accusations' impact on social cohesion, with some suggesting cooperation and others distrust.
  • Empirical evidence quantifying witchcraft labels' role in structuring cooperation within communities is scarce.

Purpose of the Study:

  • To empirically demonstrate how witchcraft labels influence cooperation and social structure in a Chinese farming community.
  • To investigate the social and reproductive consequences of being labeled 'zhu'.

Main Methods:

  • Qualitative and quantitative analysis of social interactions within a Chinese farming community.
  • Examination of gift-giving, farm help, and reproductive partnerships based on 'zhu' household status.

Main Results:

  • Households labeled 'zhu' exhibited reduced cooperation (gifts, farm help) with non-'zhu' households.
  • 'Zhu' households preferentially cooperated and reproduced amongst themselves.
  • Assortment was not based on perceived cooperativeness or individual quality, suggesting other drivers.

Conclusions:

  • The 'zhu' label significantly structures social and reproductive behavior, creating in-group/out-group dynamics.
  • Stigmatization may have originated as a mechanism to disadvantage female competitors.
  • Fear of trait transmissibility could explain the persistence of this cultural belief.
