Typical fern spores are less than one tenth of a millimeter in diameter and are readily carried to far off places by the wind. Having such small propagules certainly contributes to the disproportionate diversity of these plants on oceanic islands. Although ferns and lycophytes (collectively pteridophytes) only account for about 4 canada goose kensington parka uk percent of the world’s vascular plant species, they can easily represent 20 percent of the species on islands. Generally speaking, the more isolated the island, the more disproportionate the contribution of pteridophytes.

Canada Goose Outlet Located in the southern Pacific, about 5000 km from North America and more than 7000 km from Australia, the Marquesas Islands are farther from a continental land mass than any other archipelago. The constituent islands are well separated from the rest of French Polynesia and about 1400 km from Tahiti and the rest of the Society Islands. The 12 major Marquesas Islands are nearly all volcanic in origin, ranging in age from about 1 to 6 million years old. In total, the archipelago accounts for about 1050 km2 of land area, goose outlet canada which is roughly the same as the city of Los Angeles or the island of Tahiti and less than the Hawaiian island of Kaua’i. Three of the islands reach an elevation exceeding 1200 m. Canada Goose Outlet

Canada Goose Jackets A comprehensive flora of the Marquesas Islands has yet to be published. However, researchers based at the National canada goose outlet authentic Tropical Botanical Garden (led by David Lorence), the Smithsonian Institution (led by Warren Wagner), and the Institut de Recherche pour le Dveloppement (led by Jacques Florence) have been studying the plants inhabiting this archipelago for more than three decades. Much of their progress has been tracked on the Flora of the Marquesas website and this information is currently being developed into a two canada goose jacket outlet sale volume Flora of the Marquesas Islands to be published in late 2018. At present, 329 native vascular plant species are listed. Remarkably, ferns and lycophytes account for 99 (30 percent) of these. canada goose outlet in vancouver There are very few islands or archipelagos with proportions that are more skewed toward pteridophytes.

Canada Goose Parka As a first step toward understanding the origins of this incredible pteridophyte diversity, I recently traveled to the Marquesas Islands, with funding from the Global Genome Initiative canada goose outlet eu and the National Science Foundation, to collect herbarium specimens and silica dried material for DNA extraction. I was joined by Ken Wood (National Tropical Botanical Garden) and Jean Franois Butaud (Consultant in Forestry and Polynesian Botany). Canada Goose Parka

uk canada goose Discovery of a new species of grass was reported for Turkey by Research Associate Robert Soreng (Smithsonian Institution) and colleagues Evren Cabi (Namik Kemal University), Lynn Gillespie (Canadian Museum of Nature), and Ekaterina Boudko (Tweed Inc.). The species is described in a recent issue of Turkish Journal of Botany (41: 189 199; 2017). In 2014, Soreng, Cabi, and Burin ngay (Nezahat Gkyiit Botanic Garden) were on a collecting trip in south central Turkey when they came canada goose outlet uk fake across an unusual, mat forming grass of the genus Alopecurus (foxtail) growing canada goose outlet buffalo alongside their new Bellardiochloa species (see Plant Press 18: 9; 2015). Boudko had just completed her master’s degree on relationships within and among Alopecurus and its allies in 2014. The debate of “is this new or just an odd form of an already known species” began. Like the best of modern detectives, they conducted DNA analysis on this mysterious grass to get more information for their hypothesis. The DNA results came in: this was new. The botanists took their specimens out for re analysis, and hit the herbaria to examine dried plants of similar taxa. They searched the published floras of Turkey, Greece, Europe, the Orient, Syria, Palestine, Sinai, Iraq, Iran, and the Soviet Union their specimens’ characteristics were not matched in any of these. It appeared they really did have a plant on their hands that was previously undescribed by the scientific community. uk canada goose

cheap Canada Goose Alopecurus goekyigitiana Cabi Soreng is named for Ali Nihat Gkyiit, an individual important for his contributions to the Illustrated Flora of Turkey and to Turkish botany. It is a pale, greyish green grass that canada goose outlet online reviews forms large mats and has long, slender steams with a short, dense, spherical inflorescence that is golden yellow in color. It was found in the Taurus Mountains, on canada goose outlet real steep, craggy, mixed sedimentary rock terrain, covered in canada goose outlet winnipeg address arid high steppe to low subalpine vegetation. The researchers believe this new grass has a small range of not more than 100 km2. Due to Alopecurus goekyigitiana limited range and the fact that it grows in a heavily grazed area, the researchers classed A. goekyingitiana as Endangered (EN) although they do hope canada goose outlet online uk that its remote and rugged environment will offer some protection. cheap Canada Goose

canada goose coats on sale A new tree species, Melicope stonei (Rutaceae), endemic to the Hawaiian island of Kaua is assessed as Critically Endangered according to IUCN criteria. The newly described Melicope is apparently restricted to unique old growth forest featuring a combination of tree species that are only found on Kauai. canada goose coats on sale

canada goose uk outlet Hard to capture on their own because they live among a unique combination of other tree species, representatives of the canada goose outlet vancouver new tree species, Melicope stonei, are around 5 to12 m tall with trunks measuring up to 25 cm in diameter.

canada goose The volcanic island of Kauai is the oldest of the high Hawaiian Islands featuring deeply eroded drainages, well defined canyons, and stunning tall coastal seacliffs. It is also the most floristically rich of the Hawaiian Islands with Melicope stonei becoming the 249th endemic plant species known from only Kauai and nowhere else on earth. canada goose

Perhaps the most striking characters of Melicope stonei are the beautiful soft pubescence on the underside of its large leaves and its ramiflorous inflorescences, meaning that the flowers spring directly from the branches below the leaves. canada goose uk black friday

Canada Goose online Interestingly, canada goose outlet in usa the new species was first collected and documented as early as 1988. Since then 94 individuals have been mapped by local botanists in regions featuring unique high canopy mesic forest. Canada Goose online

In their paper, Ken Wood (National Tropical Botanical Garden), Marc Appelhans (University of Gttingen, Germany), and Warren Wagner (Smithsonian Institution) also raise concerns on canada goose outlet online store the conservation status of this unique tree which is severely limited to a 1.5 km2 area of occupancy on Kauai. “Unfortunately, in Hawaii alone canada goose outlet store calgary there are 424 federally threatened and endangered plant taxa with very few research biologists and limited funding available to adequately monitor and protect them,” explains the team of scientists. “We are hoping for a renaissance in the natural sciences whereby society values the perpetuation of species diversity with as much enthusiasm as perhaps sports and canada goose outlet shop entertainment.” canada goose clearance sale

canada goose black friday sale “With respect to previous research scientists, we are pleased to name Melicope stonei in honor of Benjamin Clemens Masterman Stone, British American botanist who had contributed over 300 publications to science during his career along with many keen insights into Hawaiian Melicope.” canada goose black friday sale

The Smithsonian’s Marine Global Earth Observatory (MarineGEO) hosted a two week bioblitz in Kaneohe canada goose outlet parka Bay, Oahu, Hawaii, at the end of May. This was a large scale inventory including researchers, students, and volunteers working to collect and observe all canada goose outlet trillium parka black algae, micro and macro fauna, fish and samples from Autonomous Reef Monitoring Structures (ARMS). During the bioblitz all participants lived and worked on Coconut Island, a 28 acre island in the bay, a quarter mile off the windward side of Oahu.
