Rare And Endemic Species: Why Are They Prone To Extinction?, Kani̇ Işik
Rare And Endemic Species: Why Are They Prone To Extinction?, Kani̇ Işik
Turkish Journal of Botany
A species is considered to be "rare" if it exhibits any one of the following attributes: (1) naturally occurs in a narrow geographical area, (2) occupies only one or a few specialised habitats, (3) forms only small population(s) in its range. An "endemic" species, however, grows naturally in a single geographical area, the size of which could be either narrow or relatively large. Not all endemic species are rare, just as not all rare species must necessarily be endemic. Many rare and/or endemic species exhibit one or more of the following attributes which make them especially prone to extinction: (1) …

Morphological And Ultrastructural Changes In Tissues Of Intermediate And Definitive Hosts Infected By Protostrongylidae, Abdurakhim Ergashevich Kuchboev, Eric P. Hoberg
Turkish Journal of Zoology
Cellular and subcellular mechanisms involved in tissue responses to larval and adult lungworms (Protostrongylidae) were respectively explored through experimental and natural infections in molluscan intermediate (Xeropicta candacharica) and ruminant definitive hosts (Ovis aries). Reaction to developing larval stages in the gastropod is manifested as cellular infiltration involving lymphocytes and macrophages into the infected tissue, which restricts damage and may result in destruction and elimination of parasites from the intermediate host. Variations in the patterns of localization for infective third-stage larvae in the foot tissue of the intermediate host are described. In the definitive host, evaluation of lung tissue by histology …
