Sorbus Aucuparia
''Sorbus aucuparia'', commonly called rowan (UK: /ˈrəʊən/, US: /ˈroʊən/) and mountain-ash, is a species of deciduous tree or shrub in the rose family. It is a highly variable species, and botanists have used different Circumscription (taxonomy), definitions of the species to include or exclude trees native to certain areas; a recent definition includes trees native to most of Europe and parts of Asia, as well as northern Africa. The range extends from Madeira, the British Isles and Iceland to Russia and northern China. Unlike many plants with similar distributions, it is not native to Japan. The tree has a slender trunk with smooth bark, a loose and roundish crown, and its leaves are pinnate in pairs of leaflets on a central vein with a terminal leaflet. It blossoms from May to June in dense corymbs of small yellowish white flowers and develops small red pomes as fruit that ripen from August to October and are eaten by many bird species. The plant is undemanding and frost h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Osmia
Mason bee is a name now commonly used for species of bees in the genus ''Osmia'', of the family Megachilidae. Mason bees are named for their habit of using mud or other "masonry" products in constructing their nests, which are made in naturally occurring gaps such as between cracks in stones or other small dark cavities. When available, some species preferentially use hollow stems or holes in wood made by wood-boring insects. Species of the genus include the orchard mason bee '' O. lignaria'', the blueberry bee '' O. ribifloris'', the hornfaced bee '' O. cornifrons'', and the red mason bee '' O. bicornis''. The former two are native to the Americas, the third to eastern Asia, and the latter to the European continent, although ''O. lignaria'' and ''O. cornifrons'' have been moved from their native ranges for commercial purposes. Over 300 species are found across the Northern Hemisphere. Most occur in temperate habitats within the Palearctic and Nearctic zones, and are active from ...

Hymenoptera Of Europe
Hymenoptera is a large order of insects, comprising the sawflies, wasps, bees, and ants. Over 150,000 living species of Hymenoptera have been described, in addition to over 2,000 extinct ones. Many of the species are parasitic. Females typically have a special ovipositor for inserting eggs into hosts or places that are otherwise inaccessible. This ovipositor is often modified into a stinger. The young develop through holometabolism (complete metamorphosis)—that is, they have a wormlike larval stage and an inactive pupal stage before they mature. Etymology The name Hymenoptera refers to the wings of the insects, but the original derivation is ambiguous. All references agree that the derivation involves the Ancient Greek πτερόν (''pteron'') for wing. The Ancient Greek ὑμήν (''hymen'') for membrane provides a plausible etymology for the term because species in this order have membranous wings. However, a key characteristic of this order is that the hindwings are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Arachnological Society
The British Arachnological Society (BAS) is the UK’s first body devoted exclusively to the study of arachnids. The primary objectives of the Society are to encourage interest in arachnology in people of all ages and to generate, promote and disseminate arachnological knowledge and understanding by all suitable means. In particular, it works to foster co-operation between amateur and professional arachnologists. Actively involved in scientific aspects of arachnid conservation, it provides impartial information and expert advice on the ecology and biology of British arachnids to policy and decision makers in Government and non-governmental organisations (NGOs), as well as to conservation practitioners, private interests and the public. The Society oversees national recording schemes for spiders, harvestmen and pseudoscorpions. Founded in 1958, it is one of the oldest societies specializing in this animal group, publishing a journal (''Arachnology'') and a Newsletter three times ...

Clubiona Subsultans
''Clubiona subsultans'', the Caledonian sac spider, is a spider from the family Clubionidae with a Palearctic distribution. Description The body length of female ''Clubiona subsultans'' varies from 5–7 mm, that of males from 5–9 mm. The tibial apophysis is pointed and has 2 barbs. The prosoma is golden-brown, the chelicerae are brownish and the legs yellow. The abdomen is reddish brown with yellow spots and a black median band with white arc-lines. Habitat and ecology ''Clubiona subsultans'' is normally found under stones and bark and in moss and litter, mostly in coniferous forests. In Britain it is called Caledonian sac-spider because the native Scots pine forest is the normal habitat. ''Clubiona subsultans'' is associated with Caledonian pine woods, where it has been found under bark, on branches, in pine litter, among young pines, and on juniper growing as an under-storey within a pine wood. Recently it was found to have been the commonest spider caught in arti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anthropogenic Climate Change
In common usage, climate change describes global warming—the ongoing increase in global average temperature—and its effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global average temperature is more rapid than previous changes, and is primarily caused by humans burning fossil fuels. Fossil fuel use, deforestation, and some agricultural and industrial practices increase greenhouse gases, notably carbon dioxide and methane. Greenhouse gases absorb some of the heat that the Earth radiates after it warms from sunlight. Larger amounts of these gases trap more heat in Earth's lower atmosphere, causing global warming. Due to climate change, deserts are expanding, while heat waves and wildfires are becoming more common. Increased warming in the Arctic has contributed to melting permafrost, glacial retreat and sea ice loss. Higher temperatures are also causing more ...

Osmia Inermis
''Osmia inermis'', the mountain mason bee , is a species of mason bee from the family Megachilidae which has a Holarctic distribution. Description A small matt black bee, the females are 10mm long and show some pale hairs on the body while the males are slightly smaller and have an entirely black pubescence over their body. Biology ''Osmia inermis'' uses preexisting cavities as nest sites up to 200 brood cells are attached to the underside of stones, to the walls of small cavities in rocks and stones or in an exceptional case to the underside of a discarded heat shield from a vehicle catalytic converter. This species will also accept overturned terracotta saucers which are left out as artificial nesting sites. Cells are entirely built of leaf mastic, a wall of sand is often constructed to seal the nest stones towards the ground. Frequently, a group of females will communally build their brood cells under the same stone. Inside the cells the broods take at least two years to matu ...

Parasitoid
In evolutionary ecology, a parasitoid is an organism that lives in close association with its host (biology), host at the host's expense, eventually resulting in the death of the host. Parasitoidism is one of six major evolutionarily stable strategy, evolutionary strategies within parasitism, distinguished by the fatal prognosis for the host, which makes the strategy close to predation. Among parasitoids, strategies range from living inside the host (''endoparasitism''), allowing it to continue growing before emerging as an adult, to Paralysis, paralysing the host and living outside it (''ectoparasitism''). Hosts can include other parasitoids, resulting in hyperparasitism; in the case of oak galls, up to five levels of parasitism are possible. Some parasitoids Behavior-altering parasite, influence their host's behaviour in ways that favour the propagation of the parasitoid. Parasitoids are found in a variety of Taxon, taxa across the insect superorder Endopterygota, whose compl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chrysura Hirsuta
''Chrysura hirsuta'', also known as the Northern Osmia ruby-tailed wasp, is a species of parasitic cuckoo wasp within the family Chrysididae. Description ''Chrysura hirsuta'' can range in length from 7 - 11 mm long. The head and mesosoma of the wasp are blue or dark green in colour, with a possible presence of golden green reflection. The metasoma of the wasp however is golden red or in rare circumstances golden green in colour. The mandibles possess a sizeable subapical tooth and the scutellum of the metathorax is flat. The flight period of ''C. hirsuta'' is between April to July. This species is believed to reproduce via thelytokous parthenogenesis, due to a higher female to male sex ratio. Distribution ''Chrysura hirsuta'' can be found within the Trans-Palearctic region from Western Europe through to East Asia. The species has been recorded in the countries and territories of: Albania, Austria, Belarus, Belgium, Czech Republic, Corsica, China, Estonia, Finland, France, Ge ...

Chrysidea
''Chrysidea'' is a genus of cuckoo wasp Commonly known as cuckoo wasps or emerald wasps, the hymenopteran family Chrysididae is a very large cosmopolitan group (over 3000 described species) of parasitoid or kleptoparasitic wasps, often highly sculptured, with brilliant metallic colors ...s (insect belonging to the family Chrysididae). Taxonomy ''Chrysidea'' and '' Trichrysis'' are closely related and probably they should be considered the same genus. For example, some authors consider the species '' Chrysidea pumila'' as a synonym of '' Trichrysis pumilionis'' Linsenmaier, 1987.
