Biology definition:Pioneer speciesis the first ones to colonize a bare substrate in primary succession while first to colonize a destroyed habitat in secondary succession.Examples:(1) a pioneer species of lyme grass (Leymus arenarius) on a barren land of sand, (2) pioneer species ofplants(e.g...
Pioneer species are the species that move into barren environments and change them to support additional species. They are the first step in a process called succession, though there are primary and secondary types of succession depending on the conditions of the environment when pioneer species arri...
Learn the pioneer species definition, how pioneer species in primary succession change the ecosystem and why lichens are successful pioneers. Pioneer species examples will be given and the question, "Why are pioneer species important?" will be answered. Related...
It is noticeable that the composition and the quantities of species in each month are not similar and there is a definite relation satisfying the law of geometrical progression between the number of seed-grains and the rank of species (Fig. 6). Here we discuss the buried-seed population ...
Tropical forest disturbances lead to the establishment of secondary successional plant communities constituted by light demanding species with high relative growth rate that conduct to rapid canopy closure. Two main strategies for N nutrition are: (a) mineral N acquisition in the form of NH4 and NO3...
Primers used for the qPCR analysis are indicated in Table 1. percent of the neonates had detectable levels of Lactobacillus GII (Fig. 1; Table 3), which includes Lactobacillus species such as L. crispatus, L. gasseri, L. jensenii, and L. acidophilus (21). In this study, it was ...

species isolated in N-free media from bulk mine tailings as well as the rhizosphere, roots, and aerial parts of pioneer plants.S. liquefaciensstrains proved to be a meta-population with high intraspecific genetic diversity and a potential to respond to these extreme conditions. The phenotypic ...
These species are mainly tetraploid, with 32 chromosomes, although diploid forms are known. Alfalfa is a herbaceous perennial legume characterized by a deep tap root showing varying degrees of branching. Erect or semi-erect stems, bearing an abundance of leaves, grow to a height of 2-3 feet....
