Pedicularis lanata is a species of flowering plant in the family Orobanchaceae. It is native to Canada and Alaska. [2] Its common names include woolly lousewort and bumble-bee flower. [1]
The plant has a wooly stem 5–25 centimetres (2.0–9.8 in) tall which grows from a bright yellow taproot. The narrow leaves are lobed or compound, the lower on long petioles. The woolly, many-flowered inflorescence is dense when new, elongating with maturity. The corolla is up to 2 centimeters long and is usually dark pink, but sometimes white. It is surrounded by toothed sepals. The fruit is a flat, beaked capsule 8–13 millimetres (0.31–0.51 in) long. The seeds have a honeycomb-patterned surface. [3] P. lanata is dependend on insect in order to set seeds. [4] [5]
P. lanata has a breeding system with high capacity for outcrossing in West Greenland (Disko) and also show great morphological variation, compared to P. flammea, P. hirsuta and P. lapponica . [6]
P. lanata is native to Canada and Alaska, and is also found in Russia and Svalbard. [7]
The Lapland longspur, also known as the Lapland bunting, is a passerine bird in the longspur family Calcariidae, a group separated by most modern authors from the Fringillidae.
The tree line is the edge of the habitat at which trees are capable of growing. It is found at high elevations and high latitudes. Beyond the tree line, trees cannot tolerate the environmental conditions. The tree line is sometimes distinguished from a lower timberline, which is the line below which trees form a forest with a closed canopy.
Verbascum thapsus, the great mullein, greater mullein or common mullein is a species of mullein native to Europe, northern Africa, and Asia, and introduced in the Americas and Australia.
Orobanchaceae, the broomrapes, is a family of mostly parasitic plants of the order Lamiales, with about 90 genera and more than 2000 species. Many of these genera were formerly included in the family Scrophulariaceae sensu lato. With its new circumscription, Orobanchaceae forms a distinct, monophyletic family. From a phylogenetic perspective, it is defined as the largest crown clade containing Orobanche major and relatives, but neither Paulownia tomentosa nor Phryma leptostachya nor Mazus japonicus.
Silene acaulis, known as moss campion or cushion pink, is a small mountain-dwelling wildflower that is common all over the high arctic and tundra and in high mountains of Eurasia and North America. It is an evergreen perennial flowering plant in the carnation family Caryophyllaceae.
Saxifraga oppositifolia, the purple saxifrage or purple mountain saxifrage, is a species of plant that is very common in the high Arctic and also some high mountainous areas further south, including northern Britain, the Alps and the Rocky Mountains.
Snow algae are a group of freshwater micro-algae which grow in the alpine and polar regions of the earth. These algae have been observed to come in a variety of colors associated with both the individual species, stage of life or topography/geography. This variation is associated with both albedo differences of the snowy habitat and the presence of micro-invertebrates. Snow algae play a critical role in the trophic organization as primary producers who in turn are consumed primarily by tardigrades and rotifers. Snow algae have also been found to travel great distances being carried by winds.
Pedicularis is a genus of perennial green root parasite plants currently placed in the family Orobanchaceae.
Douglas Barton Osborne Savile was an Irish-born Canadian mycologist, plant pathologist and evolutionary biologist. He is particularly renowned for his unique work on the coevolution of host plants and their rust fungi.
Bombus polaris is a common Arctic bumblebee species. B. polaris is one of two bumblebees that live above the Arctic Circle. The other is its social parasite Bombus hyperboreus. B. polaris is a social bee that can survive at near freezing temperatures. It has developed multiple adaptations to live in such cold temperatures. B. polaris has a thicker coat of hair than most bees, utilizes thermoregulation, and makes insulated nests.
Pedicularis contorta is a species of flowering plant in the family Orobanchaceae known by the common names coiled lousewort and curved-beak lousewort. It is native to western North America, including southwestern Canada and the northwestern United States, where it grows in moist mountainous habitat, such as bogs, shady forests, and meadows. It is a perennial herb producing one or more stems up to 40 centimetres (16 in) tall from a caudex. The leaves are up to 18 centimetres (7.1 in) long, lance-shaped to oblong, and divided into many linear lobes which may be toothed or smooth-edged. The inflorescence is a raceme of flowers occupying the top of the stem. Each flower is a centimeter long or slightly longer, white to yellowish in color, and divided into a coiled or curved beak-like upper lip and a flat, three-lobed lower lip. The fruit is a capsule up to a centimeter long containing seeds with netted surfaces.
Pedicularis howellii is an uncommon species of flowering plant in the family Orobanchaceae known by the common name Howell's lousewort. It is endemic to the Siskiyou Mountains of the Klamath Range in southern Oregon and northern California, where it grows on the edges of coniferous forests. This is a perennial herb producing one or more stems up to 45 centimetres (18 in) tall from a long caudex. The leaves are up to 20 centimetres (8 in) long, lance-shaped, and divided into many toothed oval lobes; those higher on the stem may be unlobed. The basal leaves fall away early. The inflorescence is a small raceme of flowers occupying the top of the stem. Each white to light purple flower is up to one centimetre long and is sickle-shaped, with a curved beak-like upper lip and a three-lobed lower lip which may be tucked into the hairy mass of sepals. The plant is pollinated by bumblebees including Bombus mixtus. Between the flowers are hairy to woolly triangular bracts. The fruit is a capsule just under a centimeter long containing seeds with netted surfaces.
Carex bigelowii is a species of sedge known by the common names Bigelow's sedge, Gwanmo sedge, and stiff sedge. It has an Arctic–alpine distribution in Eurasia and North America, and grows up to 50 centimetres (20 in) tall in a variety of habitats.
Salix brachycarpa is a species of flowering plant in the willow family known by the common names barren-ground willow, small-fruit willow and shortfruit willow.
Salix glauca is a species of flowering plant in the willow family known by the common names gray willow, grayleaf willow, white willow, and glaucous willow. It is native to North America, where it occurs throughout much of Alaska, northern and western Canada, and the contiguous United States south through the Rocky Mountains to northern New Mexico. It can also be found in Greenland, northwestern Europe, and Siberia.
Salix hastata is a species of flowering plant in the willow family, known by the common name halberd willow. It has an almost circumpolar distribution, occurring throughout the northern latitudes of the Northern Hemisphere, most frequently found near the coast of the Arctic Ocean. In Alaska, it occurs in the north and in the central mountains. It also occurs in northwestern Canada, and in Norway and Russia, as well as various alpine or mountainous areas of Eurasia.
Aciphylla aurea is a species of Aciphylla, commonly known as golden speargrass or golden Spaniard. Individual plants may be up to 100 cm (39 in) tall, and consist of sharp spiky yellowish-green leaves. A. aurea is found throughout the South Island of New Zealand, usually in mountainous areas but also lower altitude dry well drained grassland sites. It is found at altitudes of 300 to 1,500 m.
A compilospecies is a genetically aggressive species which acquires the heredities of a closely related sympatric species by means of hybridisation and comprehensive introgression. The target species may be incorporated to the point of despeciation, rendering it extinct. This type of genetic aggression is associated with species in newly disturbed habitats, weed species and domestication. They can be diploid or polyploid, as well as sexual or primarily asexual. The term compilospecies derives from the Latin word compilo, which means to seize, to collect, to rob or to plunder. A proposed explanation for the existence of such a species with weak reproductive barriers and frequent introgression is that it allows for genetic variation. An increase in the gene pool through viable hybrids can facilitate new phenotypes and the colonisation of novel habitats. The concept of compilospecies is not frequent in scientific literature and may not be fully regarded by the biological community as a true evolutionary concept, especially due to low supporting evidence.
