Botanical Terms -Adaxial oriented toward the axis of a surface  Botanical Terms -adaptive value (fitness, fitness, and selective value according to Darwin)8/8/2024 Botanical Terms -adaptive value (fitness, fitness, and selective value according to Darwin) The ratio of genetic benefits to drawbacks that establishes a species' (or *genotype's) propensity to endure and procreate in a certain habitat. Which people are most suited to accomplish this depends on their surroundings and the competition or fight for survival they face; the "fittest" individual (or genotype) is the one who generates the greatest number of offspring that eventually reach reproductive maturity. The "survival of the fittest" has been used to characterize this type of natural selection.  Botanical Terms -adaptive radiation 1. A sudden explosion of *evolution that led to the exploitation of a variety of *habitats and swift divergence from a single ancestral form. The word appears at several taxonomic ranks. 2. A term that several authors use as a synonym for *cladogenesis.  Botanical Terms -adaptive peaks and valleys The Darwinian fitness or *adaptive value of genotypic combinations will be represented symbolically on a contour map. Typically show adaptive peaks and valleys, which happen at the strong and weak regions of fitness, respectively. As a result, the distribution of the adaptive peaks and the *population of a particular *species will coincide.  Botanical Terms - adaptive pathway a sequence of tiny adaptive steps as opposed to one big one that allows one to pass an environmental and adaptive threshold and enter a new adaptive zone. Small adjustments add up over time to make the organism essentially pre-adapted to the new environment  Botanical Terms - adaptive breakthrough A shift in the course of evolution brought about by the adoption of a unique adaptation that allows a population or taxon to shift from one compatible zone to another. Such movements could, at their most extreme, be from air to land or from sea to land.  Botanical Terms -adaptation that which an organism can use to its full potential in a particular environmental zone while also fitting it generally.  Botanical Terms -Michel Adanson (1727–1806) a French collector and botanist who served as a clerk on a commercial mission in Senegal and made numerous previously unidentified plant discoveries. He brought back a sizable collection of plants and seeds to France in the 1750s. Despite later discoveries that specimens of the baobab were more widely dispersed, he was the first European to describe the plant, which he had seen in West Africa. He calculated that the tree he observed was roughly 5000 years old; nevertheless, radiocarbon dating has verified that some specimens are 1000 years old, while less accurate techniques have calculated older ages for other specimens. In his honor, the baobab genus (*Adansonia) was named. Adansonia is a genus of trees in the family *Bombacaceae, some species of which are pollinated by ants living inside of modified spines. The baobab (A. digitata) is well-known for its enormously enlarged trunk, which may grow to a height of 35 m and a circumference of 15 m. Some species swell, although not as much. Baobab offers food and medications for both humans and animals. There are nine species, which can be found in Madagascar, northwestern Australia, and the seasonal tropics of Africa.  Botanical Terms -aculeate The word is prickly and sharp, and comes from the Latin aculeatus, which means sting, from the word acus, needle.shrewd tapering off somewhat  |
