Valley Elderberry Longhorn Beetle
The valley elderberry longhorn beetle (''Desmocerus californicus dimorphus'') is a subspecies of longhorn beetle native to the riparian forests of the Central Valley (California), Central Valley of California from Redding, California, Redding to Bakersfield, California, Bakersfield. It is listed as a federally threatened species; a proposal to delist the insect was withdrawn in 2014. Description Valley elderberry longhorn beetles are stout-bodied. Males range in length from about 1.25–2.5 cm (½–1 in; measured from the front of the head to the end of the abdomen) with antenna (biology), antennae about as long as their bodies. Females are slightly more robust than males, measuring about 1.9–2.5 cm (¾–1 in), with somewhat shorter antennae. Adult males have red-orange elytron, elytra (wing covers) with four elongate spots and margins. The red-orange fades to yellow on some museum specimens. Adult females have dark-colored elytra with reddish margins. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pupa
A pupa ( la, pupa, "doll"; plural: ''pupae'') is the life stage of some insects undergoing transformation between immature and mature stages. Insects that go through a pupal stage are holometabolous: they go through four distinct stages in their life cycle, the stages thereof being egg, larva, pupa, and imago. The processes of entering and completing the pupal stage are controlled by the insect's hormones, especially juvenile hormone, prothoracicotropic hormone, and ecdysone. The act of becoming a pupa is called pupation, and the act of emerging from the pupal case is called eclosion or emergence. The pupae of different groups of insects have different names such as ''chrysalis'' for the pupae of butterflies and ''tumbler'' for those of the mosquito family. Pupae may further be enclosed in other structures such as cocoons, nests, or shells. Position in life cycle The pupal stage follows the larval stage and precedes adulthood (''imago'') in insects with complete metamorphosi ...

Lepturinae
Lepturinae, the lepturine beetles, is a subfamily of the longhorn beetle family (Cerambycidae), containing about 150 genera worldwide. This lineage is most diverse in the Northern Hemisphere. Until recently the subfamily Necydalinae was included within the lepturines, but this has been recently recognized as a separate subfamily. Nine tribes are usually recognized today, with a tenth, Caraphiini, created in 2016. A few genera are of uncertain placement within the subfamily. Usually among the smaller members of their family, these beetles are of a slender shape – particularly the thorax is markedly less wide than the wings, while the elytra tips are often pointed. They differ from most other longhorn beetles in that the antennae are not directly adjacent to the compound eyes. Hence, the latter are generally oval in outline, rather than having an indentation where the antennae originate, or even being divided by them. In addition, sexual dichromatism is not infrequently see ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Herbicide
Herbicides (, ), also commonly known as weedkillers, are substances used to control undesired plants, also known as weeds.EPA. February 201Pesticides Industry. Sales and Usage 2006 and 2007: Market Estimates. Summary in press releasMain page for EPA reports on pesticide use ihere Selective herbicides control specific weed species, while leaving the desired crop relatively unharmed, while non-selective herbicides (sometimes called total weedkillers in commercial products) can be used to clear waste ground, industrial and construction sites, railways and railway embankments as they kill all plant material with which they come into contact. Apart from selective/non-selective, other important distinctions include ''persistence'' (also known as ''residual action'': how long the product stays in place and remains active), ''means of uptake'' (whether it is absorbed by above-ground foliage only, through the roots, or by other means), and ''mechanism of action'' (how it works).

Insecticide
Insecticides are substances used to kill insects. They include ovicides and larvicides used against insect eggs and larvae, respectively. Insecticides are used in agriculture, medicine, industry and by consumers. Insecticides are claimed to be a major factor behind the increase in the 20th-century's agricultural productivity. Nearly all insecticides have the potential to significantly alter ecosystems; many are toxic to humans and/or animals; some become concentrated as they spread along the food chain. Insecticides can be classified into two major groups: systemic insecticides, which have residual or long term activity; and contact insecticides, which have no residual activity. The mode of action describes how the pesticide kills or inactivates a pest. It provides another way of classifying insecticides. Mode of action can be important in understanding whether an insecticide will be toxic to unrelated species, such as fish, birds and mammals. Insecticides may be repellent ...

Argentine Ant
The Argentine ant (''Linepithema humile''), formerly ''Iridomyrmex humilis'', is an ant native to northern Argentina, Uruguay, Paraguay, Bolivia and southern Brazil. It is an invasive species that has been established in many Mediterranean climate areas, inadvertently introduced by humans to many places, including South Africa, New Zealand, Japan, Easter Island, Australia, Europe, Hawaii, and the continental United States. Description The worker ants are long and can easily squeeze through cracks and holes as small as in size. Queens are long, much smaller than other species of ants. These ants will set up quarters in the ground, in cracks in concrete walls, in spaces between boards and timbers, even among belongings in human dwellings. In natural areas, they generally nest shallowly in loose leaf litter or beneath small stones, due to their poor ability to dig deeper nests. However, if a deeper nesting ant species abandons their nest, Argentine ant colonies will readily ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat Fragmentation
Habitat fragmentation describes the emergence of discontinuities (fragmentation) in an organism's preferred environment (habitat), causing population fragmentation and ecosystem decay. Causes of habitat fragmentation include geological processes that slowly alter the layout of the physical environment (suspected of being one of the major causes of speciation), and human activity such as land conversion, which can alter the environment much faster and causes the extinction of many species. More specifically, habitat fragmentation is a process by which large and contiguous habitats get divided into smaller, isolated patches of habitats. Definition The term habitat fragmentation includes five discrete phenomena: * Reduction in the total area of the habitat * Decrease of the interior: edge ratio * Isolation of one habitat fragment from other areas of habitat * Breaking up of one patch of habitat into several smaller patches * Decrease in the average size of each patch of habitat ...

Folsom Lake
Folsom Lake is a reservoir on the American River in the Sierra Nevada foothills of California, United States. It is located within Placer, El Dorado, and Sacramento Counties. It is about northeast of Sacramento. The lake surface area is , its elevation is , and it has of undulated shoreline. Folsom Lake with its surrounding Folsom Lake State Recreation Area is one of the most visited parks in the California park system. The California Office of Environmental Health Hazard Assessment has developed a safe eatinadvisoryfor Folsom Lake based on levels of mercury found in fish caught here. History The Folsom Lake reservoir is formed by Folsom Dam, built in 1955 to control and retain the American River. The dam and reservoir are part of the Folsom Project, which also includes the Nimbus afterbay reservoir and dam facilities. The Folsom Project, operated by the United States Bureau of Reclamation, is part of the Central Valley Project, a multipurpose project that provides flood co ...

Cosumnes River
The Cosumnes River is a river in northern California in the United States. It rises on the western slope of the Sierra Nevada and flows approximately into the Central Valley, emptying into the Mokelumne River in the Sacramento-San Joaquin Delta. The Cosumnes is one of very few rivers in the western Sierra without major dams. The Nature Conservancy's Cosumnes River Preserve is located just upstream from the Delta. Towns and cities along the Cosumnes River include Plymouth, Rancho Murieta, Sloughhouse, Wilton, Elk Grove, and Galt. The California Office of Environmental Health Hazard Assessment has issued aadvisoryregarding fish caught from the body of water. Name The Cosumnes River is thought to have been named as the Mokelumne and Tuolumne rivers were, using the "-umne" suffix meaning "people of". The prefix is derived from the Miwok word "kosum" meaning "salmon". Chinook Salmon runs are rarely, if ever, seen above Rancho Murieta as a result of diversions in the area. M ...

Elderberry
''Sambucus'' is a genus of flowering plants in the family Adoxaceae. The various species are commonly called elder or elderberry. The genus was formerly placed in the honeysuckle family, Caprifoliaceae, but was reclassified as Adoxaceae due to genetic and morphological comparisons to plants in the genus ''Adoxa''. Description The oppositely arranged leaves are pinnate with 5–9 leaflets (or, rarely, 3 or 11). Each leaf is long, and the leaflets have serrated margins. They bear large clusters of small white or cream-colored flowers in late spring; these are followed by clusters of small black, blue-black, or red berries (rarely yellow or white). Color Sambucus fruit is rich in anthocyanidinsColors Derived from Agricultural Products |
Imago
In biology, the imago (Latin for "image") is the last stage an insect attains during its metamorphosis, its process of growth and development; it is also called the imaginal stage, the stage in which the insect attains maturity. It follows the final ecdysis of the immature instars.Carpenter, Geo. H., The Life-Story of Insects. Cambridge University Press 1913. May be downloaded from: https://www.gutenberg.org/ebooks/16410 or https://archive.org/details/thelifestoryofin16410gut In a member of the Ametabola or Hemimetabola, in which metamorphosis is "incomplete", the final ecdysis follows the last immature or '' nymphal'' stage. In members of the Holometabola, in which there is a pupal stage, the final ecdysis follows emergence from the pupa, after which the metamorphosis is complete, although there is a prolonged period of maturation in some species. The imago is the only stage during which the insect is sexually mature and, if it is a winged species, has functional wings. The i ...

Larva
A larva (; plural larvae ) is a distinct juvenile form many animals undergo before metamorphosis into adults. Animals with indirect development such as insects, amphibians, or cnidarians typically have a larval phase of their life cycle. The larva's appearance is generally very different from the adult form (''e.g.'' caterpillars and butterflies) including different unique structures and organs that do not occur in the adult form. Their diet may also be considerably different. Larvae are frequently adapted to different environments than adults. For example, some larvae such as tadpoles live almost exclusively in aquatic environments, but can live outside water as adult frogs. By living in a distinct environment, larvae may be given shelter from predators and reduce competition for resources with the adult population. Animals in the larval stage will consume food to fuel their transition into the adult form. In some organisms like polychaetes and barnacles, adults are immobil ...
