Mate Choice

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.

Communication

Communication

Communication between two animals occurs when one animal transmits an information signal that causes a change in the animal that receives the information. Organisms communicate with one another in a host of different ways. Signals can be auditory, chemical, visual, tactile, or a combination of these. Communication is a critical behavioral adaptation that promotes survival, growth, and reproduction.

Convergent Evolution

Convergent Evolution

Evolution shapes the features of organisms over time, ensuring that they are suited for the environments in which they live. Sometimes, selection pressure leads to the rise of similar but unrelated adaptations in organisms with no recent common ancestors, a process known as convergent evolution.The structures that arise from convergent evolution are called analogous structures. They are similar in function even if they are dissimilar in structure. Further, structures can be analogous while also...

Natural Selection and Mating Preferences

Natural Selection and Mating Preferences

The principle of natural selection posits that organisms better adapted to their environment are more likely to survive and reproduce. This principle is closely intertwined with mating preferences, a key aspect of sexual selection, which evolutionary psychologists believe is driven by instincts to propagate one's genes. Such instincts significantly influence mating behaviors and preferences between genders.
Females, due to their biological roles in conception, pregnancy, and nursing, inherently...

Frequency-dependent Selection

Frequency-dependent Selection

When the fitness of a trait is influenced by how common it is (i.e., its frequency) relative to different traits within a population, this is referred to as frequency-dependent selection. Frequency-dependent selection may occur between species or within a single species. This type of selection can either be positive—with more common phenotypes having higher fitness—or negative, with rarer phenotypes conferring increased fitness.Positive Frequency-Dependent SelectionIn positive...

Understanding Species and Reproductive Barriers

Understanding Species and Reproductive Barriers

A species is a group of organisms that interbreed and produce fertile offspring. Typically, individuals of the same species appear similar and share common characteristics due to their highly similar genomes. However, not all organisms that look alike are members of the same species. Various mechanisms keep most species discrete. While some mechanisms prevent reproductive behavior and fertilization (pre-zygotic isolation), others prevent the production of fertile offspring after mating has...

Area of Science:

Animal behavior
Evolutionary biology
Bioacoustics

Background:

Male field crickets produce advertisement and courtship calls for mating.
The function of courtship calls in signaling male quality is not well understood.

Purpose of the Study:

To investigate if the courtship call of Teleogryllus commodus signals male quality.
To examine the effects of inbreeding on cricket courtship calls and life history traits.

Main Methods:

Compared courtship calls and life history traits of inbred and outbred male crickets.
Assessed changes in fine-scale call structure and multivariate attractiveness.

Main Results:

Inbreeding reduced nymph survival but did not significantly affect weight or development time.
Inbreeding caused minor changes in two of six measured courtship call parameters.
No significant difference was found in the multivariate attractiveness of inbred versus outbred male calls.

Conclusions:

The courtship call of Teleogryllus commodus does not reliably signal male quality aspects affected by inbreeding.
Courtship calls may signal fitness components unaffected by changes in heterozygosity.
