Silver-studded Blue
The silver-studded blue (''Plebejus argus'') is a butterfly in the family Lycaenidae. It has bright blue wings rimmed in black with white edges and silver spots on its hindwings, lending it the name of the silver-studded blue. ''P. argus'' can be found across Europe and east across the Palearctic, but it is most often studied in the United Kingdom where the species has experienced a severe decline in population due to habitat loss and fragmentation. ''P. argus'' engages in mutualism with ants that contribute to the butterflies' reproductive fitness by providing protection from predation and parasitism from the point of egg laying to their emergence as adults. ''P. argus'' adults emerge at the end of June and beginning of July and engage in flight until the beginning of August. The butterfly is adaptable to different habitats and is found in heathland, mossland, and limestone grassland. Tending towards a sedentary lifestyle and typically flying less than a day, ''P. argus'' main ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ericaceae
The Ericaceae () are a Family (biology), family of flowering plants, commonly known as the heath or heather family, found most commonly in acidic and infertile growing conditions. The family is large, with about 4,250 known species spread across 124 genera, making it the 14th most species-rich family of flowering plants. The many well known and economically important members of the Ericaceae include the cranberry, blueberry, huckleberry, rhododendron (including azaleas), and various common heaths and heathers (''Erica (plant), Erica'', ''Cassiope'', ''Daboecia'', and ''Calluna'' for example). Description The Ericaceae contain a morphologically diverse range of taxa, including Herbaceous plant, herbs, chamaephyte, dwarf shrubs, shrubs, and trees. Their leaves are usually evergreen, alternate or whorled, simple and without stipules. Their flowers are Plant sexuality#Individual plant sexuality, hermaphrodite and show considerable variability. The petals are often fused (sympetalous ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bracken
Bracken (''Pteridium'') is a genus of large, coarse ferns in the family (biology), family Dennstaedtiaceae. Ferns (Pteridophyta) are vascular plants that undergo alternation of generations, having both large plants that produce spores and small plants that produce gamete, sex cells (eggs and sperm) in its life cycle. Brackens are noted for their large, highly divided leaves. They are found on all continents except Antarctica and in all environments except deserts, though their typical habitat is moorland. The genus probably has the widest distribution of any fern in the world. The word ''bracken'' is of Old Norse origin, related to Swedish ''bräken'' and Danish ''bregne'', both meaning fern. In the past, the genus was commonly treated as having only one species, ''Pteridium aquilinum'', but the recent trend is to subdivide it into about ten species. Like other ferns, brackens do not have seeds or fruit, but reproduce by spores. The immature fronds, known as ''fiddleheads'', ar ...

Ulex Europaeus
''Ulex europaeus'', commonly known as gorse, common gorse, furze or whin, is a species of flowering plant native to Western Europe. Description Growing to tall, it is an evergreen shrub. The young stems are green, with the shoots and leaves modified into green spines, long. Young seedlings produce normal leaves for the first few months; these are trifoliate, resembling a small clover leaf. The solitary flowers are yellow, long, with the pea-flower structure typical of the Fabaceae; they are produced throughout the year, but mainly over a long period in spring. They are coconut-scented. The fruit is a legume (pod) long, dark purplish-brown, partly enclosed by the pale brown remnants of the flower; the pod contains 2–3 small blackish, shiny, hard seeds, which are ejected when the pod splits open in hot weather. Seeds remain viable for 30 years. Like many species of gorse, it is often a fire-climax plant, which readily catches fire but re-grows from the roots after the f ...

Erica Cinerea
''Erica cinerea'', the bell heather, is a species of flowering plant in the heath family Ericaceae, native to western and central Europe. Description It is a low, spreading shrub growing to tall, with fine needle-like leaves long arranged in whorls of three. The flowers are bell-shaped, purple (rarely white), long, produced in mid- to late summer. The flowers are dry, similar in texture to the strawflower. Etymology The Latin specific epithet ''cinerea'' means "ash coloured". Distribution and habitat ''E. cinerea'' is native to the west of Europe, where it is most abundant in Britain and Ireland, France, northern Spain and southern Norway. It also occurs in the Faroe Islands, Belgium, Germany, north-western Italy, and the Netherlands. It mostly occurs on moors and heathland with relatively dry, acidic, nutrient poor soils. It occurs in coastal dune heath and dune slack and occasionally in woodland. Ecology The plant provides a great deal of nectar for pollinators. It w ...

Calluna
''Calluna vulgaris'', common heather, ling, or simply heather, is the sole species in the genus ''Calluna'' in the flowering plant family Ericaceae. It is a low-growing evergreen shrub growing to tall, or rarely to and taller, and is found widely in Europe and Asia Minor on acidic soils in open sunny situations and in moderate shade. It is the dominant plant in most heathland and moorland in Europe, and in some bog vegetation and acidic pine and oak woodland. It is tolerant of grazing and regenerates following occasional burning, and is often managed in nature reserves and grouse moors by sheep or cattle grazing, and also by light burning. Description ''Calluna'' can reach in height. It has small-scale leaves (less than 2–3 mm long) borne in opposite and decussate pairs, whereas those of '' Erica'' are generally larger and in whorls of 3–4, sometimes 5.

Erica Tetralix
''Erica tetralix'', the cross-leaved heath, is a species of flowering plant in the family Ericaceae, native to western Europe. Description It is a perennial subshrub with glandular leaves in whorls of four (whence the name). Appearing in summer and autumn, small pink bell-shaped flowers droop in compact clusters at the ends of the shoots. Similar species Related species '' E. cinerea'' has glabrous leaves in whorls of three. ''Calluna vulgaris'' has much smaller and scale-like leaves in opposite and decussate pairs. Taxonomy The sticky, adhesive glands on leaves, sepals and other parts of the plant prompted Charles Darwin to suggest that this species might be a protocarnivorous plant, but little, if any, research has been done on this. Distribution and habitat ''E. tetralix'' is native to western Europe from southern Portugal to central Norway, as well as a number of boggy regions further from the coast in Central Europe such as Austria and Switzerland. It has also ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Metapopulation
A metapopulation consists of a group of spatially separated populations of the same species which interact at some level. The term metapopulation was coined by Richard Levins in 1969 to describe a model of population dynamics of insect pests in agricultural fields, but the idea has been most broadly applied to species in naturally or artificially fragmented habitats. In Levins' own words, it consists of "a population of populations". A metapopulation is generally considered to consist of several distinct populations together with areas of suitable habitat which are currently unoccupied. In classical metapopulation theory, each population cycles in relative independence of the other populations and eventually goes extinct as a consequence of demographic stochasticity (fluctuations in population size due to random demographic events); the smaller the population, the more chances of inbreeding depression and prone to extinction. Although individual populations have finite life-span ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
