Mixed genes appear to drive hybrid birds to select more difficult routes than their parent species, according to new research from University of British Columbia zoologists.
Serendipity leads University of Kansas scientists to the discovery and description of Rhipidocyrtus muiri - a 107 year old, lost in collections specimen, which turned out to represent a new genus and species.
In regards to recent discussion, leaders of the Entomological Society of America's SysEB Section support museum collections that house biological specimens, and encourage future collecting
The annual Twilight Seminars at Norway Gardens are presented every Tuesday evening in June.
The supposedly widespread and variable Australasian liverwort species Radula buccinifera is nothing of the kind. The species was described in 1844, and reported for New Zealand in 1855.
Dramatic shifts in the planet's climate and geography over millions of years changed the course of evolutionary history for conifer trees.
In a major effort to speed up the process of officially recognizing new plant species, botanists will no longer be required to provide Latin descriptions of new species, and publication in online academic journals and books will be considered as valid as print publication.
Important changes that will affect the publication of new names in algae, fungi, and plants accepted by the XVIII International Botanical Congress are detailed in a paper that is being published simultaneously or will be published soon in a total of sixteen leading academic journals.
The Nomenclature Section of the 18th International Botanical Congress in Melbourne, in July 2011, proposed and approved sweeping changes to the way scientists name new plants, algae, and fungi.
Dryinus grimaldii is an extinct species of wasp that is classified within the Dryinidae family and was once found in Hispaniola. This species was first discovered encased in amber on the island of Hispaniola and is known from five female individuals. Both the holotype, the original specimen used to describe the species, and the paratype, the individual studied to further describe the species, are encased in orange amber and stored at the American Museum of Natural History in New York City....
Cultigen is a plant that is the result of human selection by primarily turning a wild plant into a cultivated plant (anthropogenic plant) with minor changes. Cultigens can either be grown as a cultivated plant or planted in the wild and left to multiply on their own. Specifically selected plants are grafted with other plant material to produce mixed tissue used to create hybrids. The naming of cultigens is derived from the International Code of Botanical Nomenclature. The Cultivated Plant...
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 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...
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...
