Adaptive behavior (ecology) In behavioral ecology, adaptive behavior is any behavior that contributes directly or indirectly to an individual's reproductive success, and is thus subject to the forces of natural selection. [1] Examples include favoring kin in altruistic behaviors, sexual selection of the most fit mate, and defending a territory ...
Tinbergen's four questions. Tinbergen's four questions, named after 20th century biologist Nikolaas Tinbergen, are complementary categories of explanations for animal behaviour. These are also commonly referred to as levels of analysis. [1] It suggests that an integrative understanding of behaviour must include ultimate (evolutionary ...
Behavioral ecology, also spelled behavioural ecology, is the study of the evolutionary basis for animal behavior due to ecological pressures. Behavioral ecology emerged from ethology after Niko Tinbergen outlined four questions to address when studying animal behaviors: What are the proximate causes, ontogeny, survival value, and phylogeny of a behavior?
Shoaling and schooling. These powder blue tangs are shoaling. They are swimming somewhat independently, but in such a way that they stay connected, forming a social group. These bluestripe snapper are schooling. They are all swimming in the same direction in a coordinated way. In biology, any group of fish that stay together for social reasons ...
Fish locomotion. Fish locomotion is the various types of animal locomotion used by fish, principally by swimming. This is achieved in different groups of fish by a variety of mechanisms of propulsion, most often by wave-like lateral flexions of the fish's body and tail in the water, and in various specialised fish by motions of the fins.
Fish intelligence. Fish intelligence is "the resultant of the process of acquiring, storing in memory, retrieving, combining, comparing, and using in new contexts information and conceptual skills" [1] as it applies to fish. Due to a common perception amongst researchers that Teleost fish are "primitive" compared to mammals and birds, there has ...
Adaptation is the evolutionary process whereby an organism becomes better able to live in its habitat or habitats. [25][26][27] 2. Adaptedness is the state of being adapted: the degree to which an organism is able to live and reproduce in a given set of habitats. [28]
Adaptation through learning. One way in which Australian animals have adjusted to the presence of the cane toad is through learned behavioural adaptations. [5][7][8] These phenotypically plastic behavioural modifications are usually induced by conditioned taste aversion.
