Edith's Checkerspot
Edith's checkerspot (''Euphydryas editha'') is a species of butterfly in the family Nymphalidae. It is a resident species of western North America and among the subspecies, entomologists have long been intrigued by their many phenotypic variations in coloration, wing length, and overall body size. Most populations are monophagous and rely on plants including ''Plantago erecta'' and '' Orthocarpus densiflorus'' as its host species in developing from eggs through to larvae, pupae, and mature butterflies. Males exhibit polygyny whereas females rarely mate more than once. Males devote most of their attention to mate acquisition, and such mate locating strategies such as hilltopping behavior has developed. Climate change and habitat destruction has impacted certain subspecies. Two subspecies in particular, ''Euphydryas editha quino'' and '' Euphydryas editha bayensis'', are currently under protection via the Endangered Species Act. Description The Edith's checkerspot can be identifie ...

Olympic National Park
Olympic National Park is a United States national park located in the State of Washington, on the Olympic Peninsula. The park has four regions: the Pacific coastline, alpine areas, the west-side temperate rainforest, and the forests of the drier east side. Within the park there are three distinct ecosystems, including subalpine forest and wildflower meadow, temperate forest, and the rugged Pacific coast. President Theodore Roosevelt originally designated the park as Mount Olympus National Monument on March 2, 1909. The monument was re-designated a national park by Congress and President Franklin D. Roosevelt on June 29, 1938. In 1976, Olympic National Park was designated by UNESCO as an International Biosphere Reserve, and in 1981 as a World Heritage Site. In 1988, Congress designated 95 percent of the park () as the Olympic Wilderness, which was renamed Daniel J. Evans Wilderness in honor of Governor and U.S. Senator Daniel J. Evans in 2017. During his tenure in the Senate, Eva ...

Pedicularis
''Pedicularis'' is a genus of perennial green root parasite plants currently placed in the family Orobanchaceae (the genus previously having been placed in Scrophulariaceae ''sensu lato''). Description Between 350 and 600 species are accepted by different authorities, mostly from the wetter northern temperate zones, as well as from South America. The highest diversity is in eastern Asia, with 352 species accepted in China alone. Taxonomy The common name lousewort, applied to several species, derives from an old belief that these plants, when ingested, were responsible for lice infestations in livestock.

Insolation
Solar irradiance is the power per unit area (surface power density) received from the Sun in the form of electromagnetic radiation in the wavelength range of the measuring instrument. Solar irradiance is measured in watts per square metre (W/m2) in SI units. Solar irradiance is often integrated over a given time period in order to report the radiant energy emitted into the surrounding environment (joule per square metre, J/m2) during that time period. This integrated solar irradiance is called solar irradiation, solar exposure, solar insolation, or insolation. Irradiance may be measured in space or at the Earth's surface after atmospheric absorption and scattering. Irradiance in space is a function of distance from the Sun, the solar cycle, and cross-cycle changes.Michael Boxwell, ''Solar Electricity Handbook: A Simple, Practical Guide to Solar Energy'' (2012), p. 41–42. Irradiance on the Earth's surface additionally depends on the tilt of the measuring surface, the height ...

Oikos (journal)
''Oikos'' is a monthly peer-reviewed scientific journal covering research in the field of ecology. It is published by Wiley-Blackwell on behalf of the Nordic Foundation Oikos. Since 2011, the editor-in-chief has been Dries Bonte of Ghent University. History The journal was established in 1949 as ''Oikos: Acta Oecologica Scandinavica'', together with the Nordic Foundation Oikos, to provide a vehicle for publishing in the growing field of ecology. The journal content would have no preference with regard to taxonomic group. In the 1970s the scope was narrowed to studies with relevance to the progress of theory in ecology. From 1949 to 1977, the journal appeared in one volume of three issues per year. From 1977 to 1987, two volumes per year were produced, and three volumes from 1987. In addition, from 1949–1975, a number of supplements were published at irregular intervals. Since 2007, the ''Oikos'' subject editors make nominations for the annual Per Brinck Oikos Award given to a ...

Instar
An instar (, from the Latin '' īnstar'', "form", "likeness") is a developmental stage of arthropods, such as insects, between each moult (''ecdysis''), until sexual maturity is reached. Arthropods must shed the exoskeleton in order to grow or assume a new form. Differences between instars can often be seen in altered body proportions, colors, patterns, changes in the number of body segments or head width. After shedding their exoskeleton (moulting), the juvenile arthropods continue in their life cycle until they either pupate or moult again. The instar period of growth is fixed; however, in some insects, like the salvinia stem-borer moth, the number of instars depends on early larval nutrition. Some arthropods can continue to moult after sexual maturity, but the stages between these subsequent moults are generally not called instars. For most insect species, an ''instar'' is the developmental stage of the larval forms of holometabolous (complete metamorphism) or nymphal forms o ...

Diapause
In animal dormancy, diapause is the delay in development in response to regular and recurring periods of adverse environmental conditions.Tauber, M.J., Tauber, C.A., Masaki, S. (1986) ''Seasonal Adaptations of Insects''. Oxford University Press It is a physiological state with very specific initiating and inhibiting conditions. The mechanism is a means of surviving predictable, unfavorable environmental conditions, such as temperature extremes, drought, or reduced food availability. Diapause is observed in all the life stages of arthropods, especially insects. Embryonic diapause, a somewhat similar phenomenon, occurs in over 130 species of mammals, possibly even in humans, and in the embryos of many of the oviparous species of fish in the order Cyprinodontiformes. Activity levels of diapausing stages can vary considerably among species. Diapause may occur in a completely immobile stage, such as the pupae and eggs, or it may occur in very active stages that undergo extensive migrat ...

Orthocarpus Densiflorus
''Orthocarpus'', or owl's-clover, is a genus of flowering plants in the family Orobanchaceae (broomrapes). They are native to North America. A number of species formerly included in ''Orthocarpus'' have been transferred to the genus ''Castilleja'', which includes the plants commonly known as Indian paintbrush. Plants of the genus are generally less than in height. Like their close relatives in genus ''Castilleja'', ''Orthocarpus'' are root hemiparasites, capable of photosynthesis but extracting water and mineral nutrients through attachment to the roots of host plants. Some animal species such as the Edith's checkerspot butterfly use these plants as hosts during ovipositing. Species , Plants of the World Online accepted the following species: *''Orthocarpus barbatus'' J.S.Cotton *''Orthocarpus bracteosus'' Benth. *''Orthocarpus cuspidatus'' Greene *''Orthocarpus holmgreniorum'' (T.I. Chuang & Heckard) L. M. Shultz & F. J. Smith *''Orthocarpus imbricatus'' Torr. ex S.Wats ...

Monophagous
A generalist species is able to thrive in a wide variety of environmental conditions and can make use of a variety of different resources (for example, a heterotroph with a varied diet). A specialist species can thrive only in a narrow range of environmental conditions or has a limited diet. Most organisms do not all fit neatly into either group, however. Some species are highly specialized (the most extreme case being monophagous, eating one specific type of food), others less so, and some can tolerate many different environments. In other words, there is a continuum from highly specialized to broadly generalist species. Description Omnivores are usually generalists. Herbivores are often specialists, but those that eat a variety of plants may be considered generalists. A well-known example of a specialist animal is the monophagous koala, which subsists almost entirely on eucalyptus leaves. The raccoon is a generalist, because it has a natural range that includes most of North ...
