Often, two or more species co-adapt and co-evolve as they develop adaptations that interlock with those of the other species, such as with flowering plants and pollinating insects. In mimicry , species evolve to resemble other species; in mimicry this is a mutually beneficial co-evolution as each of a group of strongly defended species (such as ...
The data provided from these studies can, however, support and enrich the understanding of a species' ecomorphological adaptations. [3] For instance, the relationship between the organization of the jaw lever-arm system, mouth size, and jaw muscle force generation and the feeding behaviour of sunfish has been investigated. [10]
An ecotype refers to organisms which belong to the same species but have different phenotypical characteristics as a result of their adaptations to different habitats. [6] Differences between these two groups is attributed to phenotypic plasticity and are too few for them to be termed as wholly different species. [ 7 ]
This indicates that incipient air breathing was developed, as well as modification of the hyoid arch towards stapes development. [5] These characteristics account for why osteichthyans are accepted as the sister group of tetrapods. [2] The elpistostegalid fish are considered the most apomorphic of fish in comparison to tetrapods. [2]
Sexual dimorphism is a morphological, phenotypic difference between males and females of the same species. [20] A common example of sexual dimorphism is difference in body size. [20] Sexual dimorphism can specifically be seen in the fish species, Lamprologus callipterus. [21]
In evolutionary biology, adaptive radiation is a process in which organisms diversify rapidly from an ancestral species into a multitude of new forms, particularly when a change in the environment makes new resources available, alters biotic interactions or opens new environmental niches.
The best known representatives of taxa that exhibit some kind of the ontogenetic niche shift are fish (e.g. migration of so-called diadromous fish between saltwater and freshwater for purpose of breeding [2]), insects (e.g. metamorphosis between different life stages; such as larva, pupa and imago [2]) and amphibians (e.g. metamorphosis from ...
Local adaptation is a mechanism in evolutionary biology whereby a population of organisms evolves to be more well-suited to its local environment than other members of the same species that live elsewhere. Local adaptation requires that different populations of the same species experience different natural selection. For example, if a species ...
