Callicera Spinolae
''Callicera spinolae'', also known as the ivy hoverfly or golden hoverfly, is a species of syrphid fly within the genus '' Callicera'' and family Syrphidae. It was first described by Italian entomologist Camillo Rondani in 1844. Like most species within the family Syrphidae, ''C. spinolae'' are mimics of stinging wasps and bees. This mimicry has evolved in order to fool predators as the species mimicked are associated with an unpleasant taste and nasty sting. This specific kind of mimicry is also known as Batesian mimicry. It has been placed onto the UK Biodiversity Action Plan list of priority species. Description ''Callicera spinolae'' have bronze coloured bodies, with an abdomen covered in golden hairs. The golden hairs form stripes down the abdomen, which causes ''C. spinolae'' to resemble wasps and bees. They also possess compound eyes and black antennae with white tips. ''Callicera spinolae'' is known to be one of the largest hoverfly species native to the United Kingdo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
IUCN
The International Union for Conservation of Nature (IUCN) is an international organization working in the field of nature conservation and sustainable use of natural resources.

Fagus Sylvatica
''Fagus sylvatica'', the European beech or common beech, is a large, graceful deciduous tree in the Fagaceae, beech family with smooth silvery-gray bark, large leaf area, and a short trunk with low branches. Description ''Fagus sylvatica'' is a large tree, capable of reaching heights of up to tall and trunk diameter, though more typically tall and up to trunk diameter. A 10-year-old sapling will stand about tall. Undisturbed, the European beech has a lifespan of 300 years; one tree at the Valle Cervara site was more than 500 years old—the oldest known in the northern hemisphere. In cultivated forest stands trees are normally harvested at 80–120 years of age. 30 years are needed to attain full maturity (as compared to 40 for Fagus grandifolia, American beech). Like most trees, its form depends on the location: in forest areas, ''F. sylvatica'' grows to over , with branches being high up on the trunk. In open locations, it will become much shorter (typically ) and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Brown Long-eared Bat
The brown long-eared bat or common long-eared bat (''Plecotus auritus'') is a small Eurasian insectivorous bat. It has distinctive ears, long and with a distinctive fold. It is extremely similar to the much rarer grey long-eared bat which was only validated as a distinct species in the 1960s. An adult brown long-eared bat has a body length of 4.5–4.8 cm, a tail of 4.1–4.6 cm, and a forearm length of 4–4.2 cm. The ears are 3.3–3.9 cm in length, and readily distinguish the long-eared bats from most other bat species. They are relatively slow flyers compared to other bat species. Habitat The brown long-eared bat is found throughout Europe, with the exception of Greece, southern Italy and southern Spain. It is found to the east up to the Urals and Caucasus. The UK distribution can be found on the National Biodiversity Network website and can be seehere Brown long-eared bats regularly utilise buildings roosting in undisturbed roof spaces either singl ...

Tawny Owl
The tawny owl (''Strix aluco''), also called the brown owl, is a stocky, medium-sized owl in the family Strigidae. It is commonly found in woodlands across Europe, as well as western Siberia, and has seven recognized subspecies. The tawny owl's underparts are pale with dark streaks, whilst its upper body may be either brown or grey (in several subspecies, individuals may be of both colours). The tawny owl typically makes its Bird nest, nest in a tree hollow, tree hole where it can protect its eggs and young against potential predators. It is bird migration, non-migratory and highly territorial: as a result, when young birds grow up and leave the parental nest, if they cannot find a vacant territory to claim as their own, they will often starve. The tawny owl is a nocturnal bird of prey. It is able to hunt successfully at night because of its vision, hearing adaptations and its ability to fly silently. It usually hunts by dropping suddenly from a perch and seizing its prey, whic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hedera Helix
''Hedera helix'', the common ivy, European ivy, King's Choice ivy, or just ivy, is a species of flowering plant in the family Araliaceae. It is native to most of Europe and parts of western Asia. Ivy is a clinging evergreen vine that grows on tree trunks, walls, and fences in gardens, waste spaces, and wild habitats. Ivy is popular as an ornamental plant, but escaped plants have become naturalised outside its native range. Ivy has considerable cultural significance and symbolism. Synonyms include ''Hedera acuta'', ''Hedera arborea'' ('tree ivy'), ''Hedera baccifera'', and ''Hedera grandifolia.'' Other common names are bindwood and lovestone. Description ''Hedera helix'' is an evergreen climbing plant, growing to high where suitable surfaces (trees, cliffs, walls) are available, and also growing as groundcover where no vertical surfaces occur. It climbs by means of aerial rootlets with matted pads which cling strongly to the substrate. The ability to climb on surfaces varies w ...

Bioindicator
A bioindicator is any species (an indicator species) or group of species whose function, population, or status can reveal the qualitative status of the environment. The most common indicator species are animals. For example, copepods and other small water crustaceans that are present in many water bodies can be monitored for changes (biochemical, physiological, or behavioural) that may indicate a problem within their ecosystem. Bioindicators can tell us about the cumulative effects of different pollutants in the ecosystem and about how long a problem may have been present, which physical and chemical testing cannot. A biological monitor or biomonitor is an organism that provides quantitative information on the quality of the environment around it. Therefore, a good biomonitor will indicate the presence of the pollutant and can also be used in an attempt to provide additional information about the amount and intensity of the exposure. A biological indicator is also the name gi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pollarding
Pollarding is a pruning system involving the removal of the upper branches of a tree, which promotes the growth of a dense head of foliage and branches. In ancient Rome, Propertius mentioned pollarding during the 1st century BCE. The practice has occurred commonly in Europe since medieval times, and takes place today in urban areas worldwide, primarily to maintain trees at a determined height or to place new shoots out of the reach of grazing animals. Traditionally, people pollarded trees for one of two reasons: for fodder to feed livestock or for wood. Fodder pollards produced "pollard hay" for livestock feed; they were pruned at intervals of two to six years so their leafy material would be most abundant. Wood pollards were pruned at longer intervals of eight to fifteen years, a pruning cycle tending to produce upright poles favored for fencing and boat construction. Supple young willow or hazel branches may be harvested as material for weaving baskets, fences, and garden cons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
