Inventory Of Rare And Endangered Plants
The ''CNPS Inventory of Rare and Endangered Plants of California'' is a botanical online database providing information on rare, threatened, and endangered California native plants. It is sponsored by the California Native Plant Society (CNPS). Description All plant taxa that the State of California or U.S. Fish and Wildlife Service list as being threatened species, endangered species, or rare species in California, are included in the lists.The Jepson Manual, Vascular Plants of California, 2nd ed., 2012 They are continually updated with additions, changes, and deletions. In 2014 the CNPS Rare Plant Program began including Lichens of Conservation Concern. The Inventory is published every three to five years and is used by the State and Federal government for conservation planning. It is used for scientific research, conservation and preservation, and enforcement of environmental laws in California. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Delphinium Bakeri 5
''Delphinium'' is a genus of about 300 species of annual and perennial flowering plants in the family (biology), family Ranunculaceae, native plant, native throughout the Northern Hemisphere and also on the high mountains of tropical Africa. The genus was erected by Carl Linnaeus. All members of the genus ''Delphinium'' are toxic to humans and livestock. The common name larkspur is shared between perennial ''Delphinium'' species and annual species of the genus ''Consolida''. Molecular data show that ''Consolida'', as well as another segregate genus, ''Aconitella'', are both embedded in ''Delphinium''. The genus name ''Delphinium'' derives from the Ancient Greek word () which means "dolphin", a name used in ''De Materia Medica'' for some kind of larkspur. Pedanius Dioscorides said the plant got its name because of its dolphin-shaped flowers. Habitat Species with short stems and few flowers such as ''Delphinium nuttallianum'' and ''Delphinium bicolor'' appear in habitats like p ...

Endangered Species
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are considered when assessing the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Books About California
A book is a medium for recording information in the form of writing or images, typically composed of many pages (made of papyrus, parchment, vellum, or paper) bound together and protected by a cover. The technical term for this physical arrangement is ''codex'' (plural, ''codices''). In the history of hand-held physical supports for extended written compositions or records, the codex replaces its predecessor, the scroll. A single sheet in a codex is a leaf and each side of a leaf is a page. As an intellectual object, a book is prototypically a composition of such great length that it takes a considerable investment of time to compose and still considered as an investment of time to read. In a restricted sense, a book is a self-sufficient section or part of a longer composition, a usage reflecting that, in antiquity, long works had to be written on several scrolls and each scroll had to be identified by the book it contained. Each part of Aristotle's ''Physics'' is called a bo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Online Botany Databases
In computer technology and telecommunications, online indicates a state of connectivity and offline indicates a disconnected state. In modern terminology, this usually refers to an Internet connection, but (especially when expressed "on line" or "on the line") could refer to any piece of equipment or functional unit that is connected to a larger system. Being online means that the equipment or subsystem is connected, or that it is ready for use. "Online" has come to describe activities performed on and data available on the Internet, for example: "online identity", "online predator", "online gambling", "online game", "online shopping", "online banking", and "online learning". Similar meaning is also given by the prefixes "cyber" and "e", as in the words "cyberspace", "cybercrime", "email", and "ecommerce". In contrast, "offline" can refer to either computing activities performed while disconnected from the Internet, or alternatives to Internet activities (such as shopping in bri ...

Flora Of California By Conservation Status
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is ''funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora''. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was first made by Jules Thurma ...

University Of California, Riverside Herbarium
The UCR Herbarium is a clearinghouse for information regarding plant species distribution in the Western hemisphere. The collection houses over 110,000 dried specimens, approximately 80,000 of which are from the United States, and 32,000 from Mexico. The collection is especially strong in the flora of Southern California and the Baja California peninsula. The Herbarium maintains an online-assessable Filemaker database of every specimen in the stacks, which is constantly updated. The Herbarium's staff makes between 5-10 thousand identifications a year for visitors who bring in plant samples, approximately 1/4 of which have been made into new specimens. In addition, the Herbarium's active collection program generates thousands of additional specimens a year. Current field projects include the flora of the San Bernardino Mountains and western Riverside County, as well as an investigation of the Curú Biological Reserve on the Nicoya Peninsula in Costa Rica. The Herbarium is an act ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Conservation Biology
Conservation biology is the study of the conservation of nature and of Earth's biodiversity with the aim of protecting species, their habitats, and ecosystems from excessive rates of extinction and the erosion of biotic interactions. It is an interdisciplinary subject drawing on natural and social sciences, and the practice of natural resource management. The conservation ethic is based on the findings of conservation biology. Origins The term conservation biology and its conception as a new field originated with the convening of "The First International Conference on Research in Conservation Biology" held at the University of California, San Diego in La Jolla, California, in 1978 led by American biologists Bruce A. Wilcox and Michael E. Soulé with a group of leading university and zoo researchers and conservationists including Kurt Benirschke, Sir Otto Frankel, Thomas Lovejoy, and Jared Diamond. The meeting was prompted due to concern over tropical deforestation, disappearin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Threatened Species
Threatened species are any species (including animals, plants and fungi) which are vulnerable to endangerment in the near future. Species that are threatened are sometimes characterised by the population dynamics measure of ''critical depensation'', a mathematical measure of biomass related to population growth rate. This quantitative metric is one method of evaluating the degree of endangerment. IUCN definition The International Union for Conservation of Nature (IUCN) is the foremost authority on threatened species, and treats threatened species not as a single category, but as a group of three categories, depending on the degree to which they are threatened: *Vulnerable species *Endangered species * Critically endangered species Less-than-threatened categories are near threatened, least concern, and the no longer assigned category of conservation dependent. Species which have not been evaluated (NE), or do not have sufficient data ( data deficient) also are not considered ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
