Bremen
Bremen (Low German also: ''Breem'' or ''Bräm''), officially the City Municipality of Bremen (german: Stadtgemeinde Bremen, ), is the capital of the German state Free Hanseatic City of Bremen (''Freie Hansestadt Bremen''), a two-city-state consisting of the cities of Bremen and Bremerhaven. With about 570,000 inhabitants, the Hanseatic city is the 11th largest city of Germany and the second largest city in Northern Germany after Hamburg. Bremen is the largest city on the River Weser, the longest river flowing entirely in Germany, lying some upstream from its mouth into the North Sea, and is surrounded by the state of Lower Saxony. A commercial and industrial city, Bremen is, together with Oldenburg and Bremerhaven, part of the Bremen/Oldenburg Metropolitan Region, with 2.5 million people. Bremen is contiguous with the Lower Saxon towns of Delmenhorst, Stuhr, Achim, Weyhe, Schwanewede and Lilienthal. There is an exclave of Bremen in Bremerhaven, the "Citybremian Overseas Port ...

Blockland, Bremen
red = Blockland in the territory of Bremen Cityreddish grey = other parts of the Western district Blockland is a landscape and nowadays a borough of Bremen, Germany. It is part of the Western municipal district and covers an area of 30.3 km2. Geography The Blockland is part of the marshes of the Hamme, a tributary of the Weser River, and the Wümme (its main source), both of which are tidal rivers. The average elevation is 1 meter above sea level. Without the dikes along the Hamme and the Wümme, it would be flooded twice a day. Since its cultivation in the 12th century, the Blockland is drained by a network of parallel trenches which cut the area into blocks, giving the area its name. Population and landuse The density of population is quite low, 14 inhabitants per square kilometre. The settlements are concentrated along the dike. Most of the land use is Greenland economy of pastures and meadows. For the inhabitants of Bremen, the Blockland is an important leisure reso ...

Dragonflies
A dragonfly is a flying insect belonging to the infraorder Anisoptera below the order Odonata. About 3,000 extant species of true dragonfly are known. Most are tropical, with fewer species in temperate regions. Loss of wetland habitat threatens dragonfly populations around the world. Adult dragonflies are characterized by a pair of large, multifaceted compound eyes, two pairs of strong, transparent wings, sometimes with coloured patches, and an elongated body. Many dragonflies have brilliant iridescent or metallic colours produced by structural colouration, making them conspicuous in flight. An adult dragonfly's compound eyes have nearly 24,000 ommatidia each. Dragonflies can be mistaken for the closely related damselflies, which make up the other odonatan infraorder ( Zygoptera) and are similar in body plan though usually lighter in build; however, the wings of most dragonflies are held flat and away from the body, while damselflies hold their wings folded at rest, along ...

Amphibians
Amphibians are four-limbed and ectothermic vertebrates of the class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this. The young generally undergo metamorphosis from larva with gills to an adult air-breathing form with lungs. Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to reptiles like lizards but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed. With their complex reproductive needs and permeable skins, amphibians are often ecological indicators; in recent decades there has been a dramatic decli ...

Great Crested Grebe
The great crested grebe (''Podiceps cristatus'') is a member of the grebe family of water birds noted for its elaborate mating display. Taxonomy The great crested grebe was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae'' under the binomial name ''Colymbus cristatus''. The great crested grebe is now the type species of the genus ''Podiceps'' that was erected by the English naturalist John Latham in 1787. The type locality is Sweden. The scientific name comes from Latin: the genus name ''Podiceps'' is from , "vent" and , "foot", and is a reference to the placement of a grebe's legs towards the rear of its body; the species name, ''cristatus'', means "crested". Three subspecies are recognised: * ''P. c. cristatus'' (Linnaeus, 1758) – Eurasia * ''P. c. infuscatus'' Salvadori, 1884 – Africa * ''P. c. australis'' Gould, 1844 – Australia, Tasmania, South Island of New Zealand Description The great creste ...
