The last stage of the moss lifecycle is shown, where the sporophytes are visible before dispersion of their spores: the calyptra (1) is still attached to the capsule (3). The tops of the gametophytes (2) can be discerned as well. Inset shows the surrounding, black poplars growing on sandy loam on the bank of a kolk, with the detail area marked.
In most species, the sporophytes are relatively large, the setae are rigid, and the calyptrae are hairy. [1] Most species have nematodontous peristomes with 32–64 teeth in their sporangium ; [ 2 ] some early-diverging genera instead have a stopper mechanism, which consists of the apical section of the columella , that seals the mouth of the ...
Adaptation affects all aspects of the life of an organism. [24] The following definitions are given by the evolutionary biologist Theodosius Dobzhansky: 1. Adaptation is the evolutionary process whereby an organism becomes better able to live in its habitat or habitats. [25] [26] [27] 2.
The capital was the city of Trikala. According to the 17th-century geographer Hajji Khalifa , the province encompassed nine kaza s (districts): Tirhala itself, Palatmina ( Platamonas ), Yenişehir i-Fenari ( Larissa ), Golo ( Volos ), Çatalca ( Farsala ), Velestin ( Velestino ), Alasonya ( Elassona ), Döminek ( Domeniko ), and Fenarbekir.
Every aspect of an organism that has a function has a history. Now, an adaptation must have a functional history: therefore we expect it must have undergone selection caused by relative survival in its habitat. It would be quite wrong to use the word adaptation about a trait which arose as a by-product. [16] [17] [verification needed]
Fruiting bodies have a short stalk from which arises a spore-bearing structure (the receptaculum) of 5–8 arched arms. These arms, initially joined at the top, disconnect and curve irregularly to expose the inner surface of each arm, which is covered with green spore-containing gleba. Spores are 3–4 × 1–1.5 μm.

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 ...
