Macroplea pubipennis (Reuter, 1875) | |
Macroplea pubipennis is a species of leaf beetle of the subfamily Donaciinae that is endemic to Finland.
The species are 6–7 millimetres (0.24–0.28 in) in length and are straw-coloured. They also have long legs and antennae. The only differences between this species and Macroplea mutica is the shape of the elytral apex and male genitalia. They are underwater species, and live at depths of 25–50 centimetres (10–20 in). [1]
The species could be found in the Baltic Sea and from Gulf of Finland to the Bothnian Bay. So far, only two places where the species were found are known: Gulf of Finland and Archipelago Sea. Outside of Finland the species are not common. [1]
The species usually feed on aquatic plants, such as Myriophyllum , Potamogeton and Zannichellia . [1]
The species are considered to be under VU status in Finland and is currently under protection of Nature Conservation Decree. They are threatened due to the construction and dredging, disturbances that are caused by boats. Also, by invasion of reeds that are unwelcome to such species, they are losing their taste for vegetation. [1]
The Baltic Sea is an arm of the Atlantic Ocean that is enclosed by Denmark, Estonia, Finland, Germany, Latvia, Lithuania, Poland, Russia, Sweden, and the North and Central European Plain.
The Caribbean Sea is a sea of the Atlantic Ocean in the tropics of the Western Hemisphere. It is bounded by Mexico and Central America to the west and southwest, to the north by the Greater Antilles starting with Cuba, to the east by the Lesser Antilles, and to the south by the northern coast of South America. The Gulf of Mexico lies to the northwest.
Finland, officially the Republic of Finland, is a Nordic country in Northern Europe. It borders Sweden to the northwest, Norway to the north, and Russia to the east, with the Gulf of Bothnia to the west and the Gulf of Finland to the south, opposite Estonia. Finland covers an area of 338,145 square kilometres (130,559 sq mi) and has a population of 5.6 million. Helsinki is the capital and largest city. The vast majority of the population are ethnic Finns. The official languages are Finnish and Swedish, of which 84.9 percent and 5.1 percent of the population speak the first as their mother tongue. Finland's climate varies from humid continental in the south to boreal in the north. The land cover is predominantly boreal forest biome, with more than 180,000 recorded lakes.
The geography of Finland is characterized by its northern position, its ubiquitous landscapes of intermingled boreal forests and lakes, and its low population density. Finland can be divided into three areas: archipelagoes and coastal lowlands, a slightly higher central lake plateau and uplands to north and northeast. Bordering the Baltic Sea, Gulf of Bothnia, and Gulf of Finland, as well as Sweden, Norway, and Russia, Finland is the northernmost country in the European Union. Most of the population and agricultural resources are concentrated in the south. Northern and eastern Finland are sparsely populated containing vast wilderness areas. Taiga forest is the dominant vegetation type.
The Gulf of Finland is the easternmost arm of the Baltic Sea. It extends between Finland to the north and Estonia to the south, to Saint Petersburg in Russia to the east, where the river Neva drains into it. Other major cities around the gulf include Helsinki and Tallinn. The eastern parts of the Gulf of Finland belong to Russia, and some of Russia's most important oil harbors are located farthest in, near Saint Petersburg. As the seaway to Saint Petersburg, the Gulf of Finland has been and continues to be of considerable strategic importance to Russia. Some of the environmental problems affecting the Baltic Sea are at their most pronounced in the shallow gulf. Proposals for a tunnel through the gulf have been made.
The Persian Gulf, sometimes called the Arabian Gulf, is a mediterranean sea in West Asia. The body of water is an extension of the Indian Ocean located between Iran and the Arabian Peninsula. It is connected to the Gulf of Oman in the east by the Strait of Hormuz. The Shatt al-Arab river delta forms the northwest shoreline.
The Scandinavian Peninsula is located in Northern Europe, and roughly comprises the mainlands of Sweden, Norway and the northwestern area of Finland.
The White Sea is a southern inlet of the Barents Sea located on the northwest coast of Russia. It is surrounded by Karelia to the west, the Kola Peninsula to the north, and the Kanin Peninsula to the northeast. The whole of the White Sea is under Russian sovereignty and considered to be part of the internal waters of Russia. Administratively, it is divided between the Arkhangelsk and Murmansk oblasts and the Republic of Karelia.
The Gulf of Bothnia is divided into the Bothnian Bay and Bothnian Sea, and it is the northernmost arm of the Baltic Sea, between Finland's west coast and the northern part of Sweden's east coast. In the south of the gulf lies Åland, between the Sea of Åland and the Archipelago Sea.
Atlantic herring is a herring in the family Clupeidae. It is one of the most abundant fish species in the world. Atlantic herrings can be found on both sides of the Atlantic Ocean, congregating in large schools. They can grow up to 45 centimetres (18 in) in length and weigh up to 1.1 kilograms (2.4 lb). They feed on copepods, krill and small fish, while their natural predators are seals, whales, cod and other larger fish.
Southwest Finland, calqued as Finland Proper, is a region in the southwest of Finland. It borders the regions of Satakunta, Pirkanmaa, Tavastia Proper (Kanta-Häme), Uusimaa, and Åland. The region's capital and most populous city is Turku, which was the capital city of Finland before Helsinki.
The Gulf of Mannar is a large shallow bay forming part of the Laccadive Sea in the Indian Ocean with an average depth of 5.8 m (19 ft). It lies between the southeastern tip of India and the west coast of Sri Lanka, in the Coromandel Coast region. The chain of low islands and reefs known as Adam’s Bridge or Rama Setu, which includes Mannar Island, separates the Gulf of Mannar from Palk Bay, which lies to the north between India and Sri Lanka. The estuaries of Thamirabarani River and Vaippar River of South India and the Malvathu Oya of Sri Lanka drain into the Gulf. The dugong is found here.
Kvarken is the narrow region of the Gulf of Bothnia separating the Bothnian Bay from the Bothnian Sea. The distance from the Swedish mainland to the Finnish mainland is around 80 km (50 mi), while the distance between the outermost islands is only 25 km (16 mi). The water depth in the Kvarken region is only around 25 metres (82 ft). The region also has an unusual rate of land rising at almost 10 mm a year.
The Archipelago Sea is a part of the Baltic Sea between the Gulf of Bothnia, the Gulf of Finland and the Sea of Åland, within Finnish territorial waters. By some definitions it contains the largest archipelago in the world by the number of islands, although many of the islands are very small and tightly clustered.
Kemp's ridley sea turtle, also called the Atlantic ridley sea turtle, is the rarest species of sea turtle and is the world's most endangered species of sea turtle. It is one of two living species in the genus Lepidochelys. The species primarily occupies habitat around the Gulf of Mexico though their migrations into the Atlantic are being affected by rising temperatures. Kemp's ridley sea turtles are currently listed as endangered under the Endangered Species Act (ESA), and current conservation efforts attempt to rebuild population numbers. Human activity, including but not limited to habitat destruction, climate change, and oil spills, threaten populations.
The Baltic Ice Lake is a name given by geologists to a freshwater lake that evolved in the Baltic Sea basin as glaciers retreated from that region at the end of the last ice age. The lake existed between 12,600 and 10,300 years Before Present (BP).
The Bothnian Bay or Bay of Bothnia is the northernmost part of the Gulf of Bothnia, which is in turn the northern part of the Baltic Sea. The land holding the bay is still rising after the weight of ice-age glaciers has been removed, and within 2,000 years the bay will be a large freshwater lake since its link to the south Kvarken is mostly less than 20 metres (66 ft) deep. The bay today is fed by several large rivers, and is relatively unaffected by tides, so has low salinity. It freezes over each year for up to six months. Compared to other parts of the Baltic, it has little plant or animal life.
The Donaciinae are a subfamily of the leaf beetles, or Chrysomelidae, characterised by distinctly long antennae. They are found in mainly the Northern Hemisphere, with some species found in the Southern Hemisphere.
Macroplea mutica is a species of leaf beetles of the subfamily Donaciinae. It considered to be a Palearctic species, but can be found in Central Europe and Turkey.
Located in the Scandinavian Peninsula, Sweden is a mountainous country dominated by lakes and forests. Its habitats include mountain heath, montane forests, tundra, taiga, beech forests, rivers, lakes, bogs, brackish, marine coasts, and cultivated land. The climate of Sweden is mild for a country at this latitude, largely owing to the significant maritime influence.
