Cycads Evolved To Grow In Groves With Seed Dispersal By Large Frugivores
2013-08-21 06:22:43

April Flowers for redOrbit.com - Your Universe Online Before the age of dinosaurs, the ancient cycad lineage existed. Cycads also co-existed more recently with large herbivorous mammals, such as the Ice Age megafauna that only went extinct a few tens of thousands of years ago. Modern cycads have large, heavy seeds with a fleshy outer coat, suggesting they rely on large bodied fruit-eating animals to disperse their seeds. However, little evidence has been found that modern larger-bodied...

Trichomes Save Insect From Beetle Predation
2013-02-06 13:07:00

University of Guam Everyone needs to eat. But it's a dog-eat-dog world, and with the exception of the top predators, everyone also gets eaten. To cope with this vicious reality, a tiny insect that eats plants has learned to employ the plant's hairs for physical protection from its beetle predator. The pest is called the cycad aulacaspis scale, and its invasion into numerous countries in recent years has caused immeasurable loss of biodiversity. Cycads belong to an ancient lineage of...

Conservation efforts need empirical studies The beautiful, endemic and endangered cycad, Cycas micronesica was once a dominant forest tree on the island of Guam, but recent plant mortality predicts extirpation from Guam habitats by 2019. This dire prediction by scientists at the Western Pacific Tropical Research Center (WPTRC), University of Guam is validated by the research of Thomas E. Marler and John H. Lawrence, which has concluded that Cycas micronesica is the only native host for the...

The palms that Vietnamese villagers weave into hats, many varieties of lichens that depend on the pristine environment of the Great Smoky Mountains, and small, shrub-like trees that are threatened by development and deforestation in Brazil were among the scores of plant and fungus species that scientists at The New York Botanical Garden discovered and described in the course of one year. As part of their effort to catalog all plant life on Earth, Botanical Garden scientists named 81 new...

From southern Africa's pineapple lily to Western Australia's swamp bottlebrush, flowering plants are everywhere.  Also called angiosperms, they make up 90 percent of all land-based, plant life. New research published this week in the Proceedings of the National Academy of Sciences provides new insights into their genetic origin, an evolutionary innovation that quickly gave rise to many diverse flowering plants more than 130 million years ago. Moreover, a flower with genetic programming...

Genetic analysis of Guam's cycads shows promising genetic diversity Cycads, "living fossil" descendents of the first plants that colonized land and reproduced with seeds, are rapidly going extinct because of invasive pests and habitat loss, especially those species endemic to islands. But new research on Cycas micronesica published recently as the cover article in Molecular Ecology calls into question the characterization of these plants as relicts (leftovers of formerly abundant organisms),...

Researchers look for small control organism "The small size of an alien insect that feeds on a native tree from the western Pacific island of Guam allows it to hide in cracks and other locations that are out of reach for its only local natural enemy," said UOG entomologist Aubrey Moore. Moore has teamed up with UOG ecologist Thomas Marler to study the relationship between the native cycad tree, known as "fadang" in the Chamorro language, and a minute alien insect pest called cycad aulacaspis...

Moth also triggers the plants into increased frequency of reproduction When a plant endemic to several islands in the Western Pacific Ocean taps the services of a helpful insect, a double-dose of benefits comes its way. The plant is a member of a unique group of plants known as cycads, which produce their seeds in cones rather than within fruits. The insect is a tiny moth currently known to exist only on the islands of Guam and Rota. The insect's primary role is to ensure seed production...

For the first time scientists have put a figure on how much it would cost to learn about the conservation status of millions of species, some of which have yet to be identified. The price tag is US$60 million, according to a team of scientists, including those from IUCN and Conservation International, who presented their case in this week's Science magazine in an article called "The Barometer of Life." "Our knowledge about species and extinction rates remains very poor, and this has negative...

Thomas Marler recently published the results of his research that reveal some of the attributes of the long-lived leaves of Guam's Cycas micronesica plants. "These leaves are relatively large and are constructed of tough tissues," said Marler. "Both of these factors indicate the construction costs of this leaf form are substantial."Green leaves must pay back their own construction costs, but each leaf is also required to supply the energy needed to maintain its live tissues throughout its...

Macrozamia communis is a type of Australian cycad plant. The species is located on the coast of New South Wales. It is commonly known as the Burrawang. Its common name is derived from the Daruk Australian Aboriginal Language. This name is often applied to other species of Macrozamia. M. communis normally has an un-branched trunk, cycad plants branch very rarely. The species has dark green colored leaves which become dull with age. This plant has separate male and female specimens that are...

Encephalartos villosus is a South African cycad, or Palm-like plant. Commonly named, poor man's cycad. The species is a member of the Zamiaceae family. It’s a common cycad between the East London vicinity and the northern border of Swaziland. The plants can be found growing several hundred miles inland. Very little of the plant is visible. E. villosus has a largely underground trunk. This has led it to be improperly categorized as a dwarf species. The crown of the plant is made up of...
