Uggleviken
Uggleviken ( sv, (the) Owl Bay) is a former bay and lake in Norra Djurgården, a semi-rural area in north-eastern central Stockholm, Sweden, forming part of the Royal National City Park. Together with Lillsjön, Laduviken and Storängsbotten, Uggleviken used to be part of a bay forking across Norra Djurgården. Today it is reduced to a marsh or a wet alder forest with patches of reeds in its centre. It is regarded as of great natural value and have been mentioned as one of the most interesting botanical and ornithological areas in Stockholm.Uggleviken History The spring of the lake first appears in historical records in the end of the 18th century and during the 19th century and early 20th century it became a popular Trinity spring to which Stockholmers in huge numbers would go on Trinity Sunday to drink at a ceremony. A pavilion constructed in 1902 is still reminding of the era.Ugglevikskällan Catchment area The marsh's catchment area, considered as one of the most impo ...

Lillsjön, Djurgården
Lillsjön ( sv, Small Lake) is a small, former lake in Norra Djurgården, a semi-rural area in north-eastern central Stockholm, Sweden, forming part of the Royal National City Park. Today transformed into a wetland, it is often mentioned as one of the six lakes in the area, the other being: Laduviken, Uggleviken, Isbladskärret, Lappkärret, and Spegeldammen. Lillsjön used to be connected to other lakes in the area through narrow straits. Through a project sponsored by the World Wide Fund for Nature, water was pumped into the small basin reinforced by new embankments. Reed was also burnt away, and the former lake thus transformed into a shore meadow attracting many birds, starting with northern lapwings in March, followed by common snipes later in spring. In autumn, many birds rest here on their way south, such as wood sandpipers, common redshanks, greenshanks, and ruffs. Upptäck A striking feature at Lillsjön are the Highland cattle residing there from May to October. N ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Laduviken
Laduviken ( sv, Barn Bay) is a lake in Norra Djurgården, a semi-rural area in north-eastern Stockholm, Sweden, forming part of the Royal National City Park. It is one of six lakes in Djurgården, the others being: Lillsjön, Uggleviken, Isbladskärret, Lappkärret, and Spegeldammen. Catchment area Most of the catchment area is composed of open grassland with scattered oaks and other hardwood. West of the lake, the buildings of the Stockholm University take up some 20 per cent of the surface and a few roads, a traffic route, the suburban railway Roslagsbanan, and the subterranean metro passes through the area. East of the lake are some minor one-family houses and commercial buildings. The terrain north of the lake is flat while the southern shore is steep and, as the area west of the lake is drained by a ditch dug through a filled-up wetland, most of the catchment area is located there and most of the inflow comes from an ooze and oil separator treating water from human-mad ...

Stormwater
Stormwater, also spelled storm water, is water that originates from precipitation (storm), including heavy rain and meltwater from hail and snow. Stormwater can soak into the soil ( infiltrate) and become groundwater, be stored on depressed land surface in ponds and puddles, evaporate back into the atmosphere, or contribute to surface runoff. Most runoff is conveyed directly as surface water to nearby streams, rivers or other large water bodies (wetlands, lakes and oceans) without treatment. In natural landscapes, such as forests, soil absorbs much of the stormwater. Plants also reduce stormwater by improving infiltration, intercepting precipitation as it falls, and by taking up water through their roots. In developed environments, such as cities, unmanaged stormwater can create two major issues: one related to the volume and timing of runoff (flooding) and the other related to potential contaminants the water is carrying (water pollution). In addition to the pollutants carr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Institute Of Technology
The KTH Royal Institute of Technology ( sv, Kungliga Tekniska högskolan, lit=Royal Institute of Technology), abbreviated KTH, is a public research university in Stockholm, Sweden. KTH conducts research and education in engineering and technology and is Sweden's largest technical university. Currently, KTH consists of five schools with four campuses in and around Stockholm. KTH was established in 1827 as the ''Teknologiska institutet (Institute of Technology)'' and had its roots in the ''Mekaniska skolan (School of Mechanics)'' that was established in 1798 in Stockholm. But the origin of KTH dates back to the predecessor of the ''Mekaniska skolan'', the ''Laboratorium mechanicum'', which was established in 1697 by the Swedish scientist and innovator Christopher Polhem. The Laboratorium mechanicum combined education technology, a laboratory, and an exhibition space for innovations. In 1877 KTH received its current name, Kungliga Tekniska högskolan (KTH Royal Institute of Technol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gastropoda
The gastropods (), commonly known as snails and slugs, belong to a large taxonomic class of invertebrates within the phylum Mollusca called Gastropoda (). This class comprises snails and slugs from saltwater, from freshwater, and from land. There are many thousands of species of sea snails and slugs, as well as freshwater snails, freshwater limpets, and land snails and slugs. The class Gastropoda contains a vast total of named species, second only to the insects in overall number. The fossil history of this class goes back to the Late Cambrian. , 721 families of gastropods are known, of which 245 are extinct and appear only in the fossil record, while 476 are currently extant with or without a fossil record. Gastropoda (previously known as univalves and sometimes spelled "Gasteropoda") are a major part of the phylum Mollusca, and are the most highly diversified class in the phylum, with 65,000 to 80,000 living snail and slug species.

Oligochaeta
Oligochaeta () is a subclass of animals in the phylum Annelida, which is made up of many types of aquatic and terrestrial worms, including all of the various earthworms. Specifically, oligochaetes comprise the terrestrial megadrile earthworms (some of which are semiaquatic or fully aquatic), and freshwater or semiterrestrial microdrile forms, including the tubificids, pot worms and ice worms ( Enchytraeidae), blackworms ( Lumbriculidae) and several interstitial marine worms. With around 10,000 known species, the Oligochaeta make up about half of the phylum Annelida. These worms usually have few setae (chaetae) or "bristles" on their outer body surfaces, and lack parapodia, unlike polychaeta. Diversity Oligochaetes are well-segmented worms and most have a spacious body cavity (coelom) used as a hydroskeleton. They range in length from less than up to in the 'giant' species such as the giant Gippsland earthworm (''Megascolides australis'') and the Mekong worm (''Amynth ...
