In botany, a diaspore is a plant dispersal unit consisting of a seed or spore plus any additional tissues that assist dispersal. In some flowering plants, the diaspore is a seed and fruit together, or a seed and elaiosome. In a few plants, the diaspore is most or all of the plant, and is known as a tumbleweed.
The Turkish diaspora (Turkish: Türk diasporası or Türk gurbetçiler) refers to ethnic Turkish people who have migrated from, or are the descendants of migrants from, the Republic of Turkey, Northern Cyprus or other modern nation-states that were once part of the former Ottoman Empire.
The flora of Turkey consists of more than 11,000 species of plants, as well as a poorly known number of fungi and algae. Around a third of Turkey 's vascular plants are found only in the country. One reason there are so many of these endemics is because Anatolia is both mountainous and quite fragmented.
A plant which completes its life cycle (i.e. germinates, reproduces, and dies) within two years or growing seasons. Biennial plants usually form a basal rosette of leaves in the first year and then flower and fruit in the second year. bifid Forked; cut in two for about half its length. Compare trifid. bifoliate
Albanian diaspora – 2.8 million live in Albania, with an estimated 8.5 million world total (the largest populations being in Italy, Greece, Turkey, the United States, Canada and Australia). The largest concentration of Albanians outside the country is in neighbouring Kosovo .
An example of the use of landscape genetics as a means to study seed dispersal, for example, involves studying the effects of traffic using motorway tunnels between inner cities and suburban area. [35] Genome wide SNP dataset and species distribution modelling are examples of computational methods used to examine different dispersal modes. [34]

In most such species, the tumbleweed is in effect the entire plant apart from the root system, but in other plants, a hollow fruit or inflorescence might detach instead. [1] Xerophyte tumbleweed species occur most commonly in steppe and arid ecosystems , where frequent wind and the open environment permit rolling without prohibitive obstruction.
