Evolutionary Timeline Of Cold Weather Adaptation In Plants
2013-12-23 04:00:05

redOrbit Staff & Wire Reports - Your Universe Online A team of researchers have compiled the largest-ever dated evolutionary tree of angiosperms, and their efforts have led to new insights into how these flowering plants changed in order to withstand winter weather. The study, which currently appears online in the journal Nature, features evolutionary information on more than 32,000 angiosperm species, including leaf and stem data. They combined that information with freezing...

Genome Sequence Insight Evolution Flowering Plants
2013-12-20 09:12:33

redOrbit Staff & Wire Reports - Your Universe Online The newly-sequenced genome of the Amborella plant is shedding new light on the origin of the more than 300,000 flowering plants on the Earth today, including all major food crop species. Amborella trichopoda, a small understory tree found only on the main island of New Caledonia in the South Pacific, is unique as the sole survivor of an ancient evolutionary lineage that traces back to the last common ancestor of all flowering...

Climate Change Alters Timing Of Spring Growth In Forests
2013-10-30 09:05:58

Technische Universitaet Muenchen In the temperate zones, vegetation follows the change of the seasons. After a winter pause, plants put out new growth in spring. Research has now brought a new correlation to light: The colder the winter, the earlier native plants begin to grow again. Since warmer winters can be expected as the climate changes, the spring development phase for typical forest trees might start later and later – giving an advantage to shrubs and invasive trees that don't...

Trees Might Store More Carbon Than Thought
2013-10-03 07:03:41

DOE/Pacific Northwest National Laboratory Examining a long-lived forest, researchers have found that Black Spruce trees, which dominate the northern forests of North America, succumb about five years after being weakened by environmental stresses. Without rejuvenating fire, the dead trees aren't being replaced by new ones. The result will help researchers better understand how climate change affects the health of forests, and how forests affect the severity of climate change. The study...

Mammal Diversity Faltered When Flowering Plants Arrived
2013-10-02 16:02:24

Brett Smith for redOrbit.com - Your Universe Online As mammals were trying to emerge from the shadows of dinosaurs 100 million years ago, there was a dramatic proliferation of flowering plant species. However, instead of early mammals benefiting from new food and shelter opportunities that would have been provided by the plants, they experienced a decline during the mid-Cretaceous. Using a morphological analysis, two researchers were able to provide these new insights about mammalian...

Flowering Plants Evolved 100 Million Years Earlier Than Believed
2013-10-02 07:55:56

[ Watch the Video: Flowering Plants Arose In The Early Triassic ] redOrbit Staff & Wire Reports - Your Universe Online Researchers from the University of Zurich in Switzerland have uncovered evidence suggesting flowering plants evolved 100 million years earlier than previously believed, according to new research appearing in the open-access journal Frontiers in Plant Science. Flowering plants evolved from extinct plants related to conifers, cycads, ginkgos and seed ferns, and the...

Understanding the impact of environmental change on plant traits is an important issue in evolutionary biology. As the only direct evidence of past life, fossils provide important information on the interactions between plants and environmental change. After ten years' survey, Professor Zhou Zhekun's group from Kunming Institute of Botany has discovered more than ten well preserved Neogene plant fossil sites in southwestern China which are important to understand past climate and response of...

Flower garden
2013-08-21 08:27:49

Flower gardens, used for beautification purposes, contain various flowering plants providing blooms all year long and can be elaborate or simple. Flower gardens come in all shapes, sizes, and colors. Formal flower gardens are planned out and serve as a multi-function garden, such as growing herbs around the border of a flower garden with edible blooms. Shrubs are also used in creating flower gardens suitable for plants requiring shade. A haphazard flower garden is one that is allowed to...

Perennial Plant
2013-04-27 08:01:21

Perennial plants live for two years or more. Perennials differ from annuals and biennials with annuals replanted every year and biennials every other year. Perennial’s that bloom during spring and summer will die back in autumn, rest during the winter, then re-grow the following spring from the existing root-stock; these are also known as deciduous perennials. If the climate is continually warm, a perennial will continually grow and produce flowers and or fruit. A perennial relocated from...

Biennial Plant
2013-04-27 07:50:37

Biennial plants have a two year life cycle; roots, stems and leaves in the first year with flowers following the next year after a cold winter dormant period. Biennials will produce seed and fruit before dying. There are not as many biennial plants as there are perennials or annuals. Biennial plants, when exposed to extreme climate conditions, may have a shortened life cycle of a few months especially if the plants were exposed to colder than normal temperatures. Most biennials can be...

Annual Plant
2013-04-27 07:44:51

Annuals are plants that flower and/or set fruit in one growing season. Most vegetables are annuals as well as domesticated grains. Vegetables such as carrot and celery are biennials grown as an annual whereas tomato and bell pepper are perennials and grown as an annual. Annuals grow well mixed in with perennials and biennials. There are also ornamental flowers that are perennials in one region and an annual in another. An annual can produce seeds that continue the life cycle in as little...

attercop
  • A spider.
  • Figuratively, a peevish, testy, ill-natured person.
'Attercop' comes from the Old English 'atorcoppe,' where 'atter' means 'poison, venom' and‎ 'cop' means 'spider.' 'Coppa' is a derivative of 'cop,' top, summit, round head, or 'copp,' cup, vessel, which refers to 'the supposed venomous properties of spiders,' says the OED. 'Copp' is still found in the word 'cobweb.'
