What is a Species?01:17

What is a Species?

Overview
Mate Choice01:20

Mate Choice

Mate choice—the decision about whom to mate with—is a type of natural selection, since animals must reproduce to pass down their genes. Mate choice is also called intersexual selection because the behavior occurs between the sexes.
Hybrid Zones02:29

Hybrid Zones

Hybrid zones are narrow regions where two closely related species interact, mate, and produce hybrids. Relative to either parent species, hybrids may possess distinct phenotypic or genetic differences that impact their survival and reproductive success. The genetic variances introduced by hybridization influence species diversity and speciation processes within the hybrid zone.
Hardy-Weinberg Principle01:49

Hardy-Weinberg Principle

Diploid organisms have two alleles of each gene, one from each parent, in their somatic cells. Therefore, each individual contributes two alleles to the gene pool of the population. The gene pool of a population is the sum of every allele of all genes within that population and has some degree of variation. Genetic variation is typically expressed as a relative frequency, which is the percentage of the total population that has a given allele, genotype or phenotype.
Energy Budgets00:51

Energy Budgets

Organisms must balance energy intake with the energy required for growth, maintenance and reproduction. These trade-offs result in a variety of survivorship and reproductive strategies, including semelparity and iteroparity. Semelparous species, like annual plants, have only one reproductive episode in their lifetimes and consequently have short lifespans. Iteroparous species, by contrast, have many reproductive events during their lifetimes but have relatively few offspring. These two...
Testing a Claim about Population Proportion01:24

Testing a Claim about Population Proportion

A complete procedure for testing a claim about a population proportion is provided here.
There are two methods of testing a claim about a population proportion: (1) Using the sample proportion from the data where a binomial distribution is approximated to the normal distribution and (2) Using the binomial probabilities calculated from the data.
The first method uses normal distribution as an approximation to the binomial distribution. The requirements are as follows: sample size is large...

Summary

Bateman's principle, applied to hermaphrodites, yields contradictory predictions regarding reproductive success and sexual conflict. Alternative models focusing on variance reduction and gamete trading better explain hermaphroditic mating systems.

Area of Science:

  • Evolutionary Biology
  • Sexual Selection
  • Reproductive Strategies

Background:

  • Bateman's principle posits differential reproductive success limits for males and females.
  • Its application to hermaphroditism generates predictions on advantages and sexual conflict.
  • Empirical data are used to test these predictions.

Purpose of the Study:

  • To evaluate the validity of Bateman's principle in explaining hermaphroditism.
  • To assess Charnov's predictions regarding hermaphroditism and Bateman's principle.
  • To explore alternative explanations for hermaphroditic mating systems.

Main Methods:

  • Comparative analysis of predictions derived from Bateman's principle and Charnov's work against empirical data.
  • Examination of reproductive variance and fixed cost hypotheses.
  • Evaluation of gamete trading and energy trading models.

Main Results:

  • Charnov's prediction on hermaphroditism occurring when Bateman's principle doesn't apply is largely supported.
  • Predictions linking hermaphroditism to low fixed costs are inconsistent with data.
  • The preferred sexual role in hermaphrodites varies, contradicting Bateman's principle.
  • Gamete trading models are more consistent with data than energy trading models.

Conclusions:

  • Bateman's principle provides a poor framework for understanding hermaphroditism and sexual selection.
  • Reducing variance in reproductive success may be a key advantage of hermaphroditism.
  • Gamete trading, not energy trading, better explains role preference in hermaphroditic systems.
