Squirrel Chase - Geograph
Squirrels are members of the family Sciuridae, a family that includes small or medium-size rodents. The squirrel family includes tree squirrels, ground squirrels (including chipmunks and prairie dogs, among others), and flying squirrels. Squirrels are indigenous to the Americas, Eurasia, and Africa, and were introduced by humans to Australia. The earliest known fossilized squirrels date from the Eocene epoch, and among other living rodent families, the squirrels are most closely related to the mountain beaver and to the dormice. Etymology The word ''squirrel'', first attested in 1327, comes from the Anglo-Norman which is from the Old French , the reflex of a Latin word , which was taken from the Ancient Greek word (; from ) 'shadow-tailed', referring to the long bushy tail which many of its members have. The native Old English word for the squirrel, , survived only into Middle English (as ) before being replaced. The Old English word is of Common Germanic ori ...

Gunnera Tinctoria Liberec 2
''Gunnera'' is the sole genus of herbaceous flowering plants in the family Gunneraceae, which contains 63 species. Some species in this genus, namely those in the subgenus ''Panke'', have extremely large leaves. Species in the genus are variously native to Latin America, Australia, New Zealand, Papuasia, Hawaii, insular Southeast Asia, Africa, and Madagascar. The stalks of many species are edible. Taxonomy ''Gunnera'' is the only genus in the family Gunneraceae. The APG II system, of 2003, also recognizes this family and assigns it to the order Gunnerales in the clade core eudicots. The family then consisted of one or two genera, ''Gunnera'' and, optionally, '' Myrothamnus'', the latter optionally segregated as a separate family, Myrothamnaceae. This represents a change from the APG system, of 1998, which firmly recognized two separate families, unplaced as to order. The APG III system and APG IV system recognizes the family Gunneraceae and places ''Myrothamnus'' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chinese Sleeper
The Chinese sleeper (''Perccottus glenii''), also known as the Amur sleeper, is a species of freshwater sleeper native to Amur River basin in eastern Asia with introduced populations in other regions of Eurasia. It is currently the only known member of its genus. Description The Chinese sleeper, known as rotan in Russia, resembles a perch, ruffe or sculpin. The eyes are placed high on the head which has a rounded snout and projecting lower jaw. There is little or no gap between the two dorsal fins, the front one of which has six to eight spines and the back one nine to eleven soft rays. The anal fin has one to three spines and seven to ten soft rays. The pelvic fins are not fused together which helps to distinguish this fish from the gobies. The second dorsal and the anal fins are both more rounded and shorter than the gobies and the caudal fin is also more rounded. The general colour is brownish with a checker-board pattern of darker marks or dark barring. There are dark lin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asian Hornet
The Asian hornet (''Vespa velutina''), also known as the yellow-legged hornet or Asian predatory wasp, is a species of hornet Indigenous (ecology), indigenous to Southeast Asia. It is of concern as an invasive species in some other countries. Appearance ''Vespa velutina'' is slightly smaller than the European hornet. Typically, queens are 30 mm (1.2 in) in length, and males about 24 mm (0.95 in). Workers measure about 20 mm (0.80 in) in length. The species has distinctive yellow Arthropod leg, tarsi (legs). The thorax is a velvety brown or black with a brown abdomen. Each abdominal segment has a narrow posterior yellow border, except for the fourth segment, which is orange. The head is black and the face yellow. Regional forms vary sufficiently in color to cause difficulties in classification, and several subspecies have been variously identified and ultimately rejected; while a history of recognizing subspecies within many of the ''Vespa'' spec ...

Myriophyllum Aquaticum - Victoriahuset, Bergianska Trädgården - Stockholm, Sweden - DSC00258
''Myriophyllum'' (water milfoil) is a genus of about 69 species of freshwater aquatic plants, with a cosmopolitan distribution. The center of diversity for ''Myriophyllum'' is Australia with 43 recognized species (37 endemic). These submersed aquatic plants are perhaps most commonly recognized for having elongate stems with air canals and whorled leaves that are finely, pinnately divided, but there are many exceptions. For example, the North American species ''M''. ''tenellum'' has alternately arranged scale like leaves, while many Australian species have small alternate or opposite leaves that lack dissection. The plants are usually heterophyllous, leaves above the water are often stiffer and smaller than the submerged leaves on the same plant and can lack dissection. Species can be monoecious or dioecious. In monoecious species plants are hermaphrodite, in dioecious species plants are either male or female, the flowers are small, 4(2)-parted and usually borne in emergent leaf ...

Myriophyllum Aquaticum
''Myriophyllum aquaticum'' is a flowering plant, a Vascular tissue, vascular Dicotyledon, dicot, commonly called parrot's-feather and parrot feather watermilfoil. Morphology and reproduction Parrot feather is a perennial plant. Parrot feather gets its name from its feather-like leaves that are arranged around the stem in whorls of four to six. The emergent stems and leaves are the most distinctive trait of parrot feather, as they can grow up to a foot above the water surface and look almost like small fir trees. The woody emergent stems grow over 5 feet long and will extend to the bank and shore. Attached to the Parrot feather are pinkish-white flowers that extend approximately 1/16 inches long. As the water warms in the spring, parrot feather begins to flourish. Most plants flower in the spring; however, some also flower in the fall. Almost all plants of this species are female, in fact there are no male plants found outside of South America. Seeds are not produced in any North A ...

Elodea Nuttallii
''Elodea nuttallii'' is a species of waterweed known by the common name western waterweed or Nuttall's waterweed. This is a perennial aquatic plant which is native to North America where it grows submersed in lakes, rivers, and other shallow water bodies. It is also found in Eurasia, where it is commonly weedy; it is not known as a weed species in its native range. It is sometimes used as an aquarium plant. Description It is similar to its relative, '' Elodea canadensis''. However, the leaves taper to an acute point. It has a thin branching stem with whorls of flat leaves at intervals. Some leaves are recurved and twisted, with minute teeth. It bears tiny flowers, the staminate ones abscissing from their stalks and floating away from the plant. It flowers from May until October. In Europe nearly all individuals are female, only some places with male plants are known. Distribution This species is native to temperate North America. It has been naturalised in Europe since 1939 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Impatiens Glandulifera
''Impatiens glandulifera'', Himalayan balsam, is a large annual plant native to the Himalayas. Via human introduction it is now present across much of the Northern Hemisphere and is considered an invasive species in many areas. Uprooting or cutting the plants is an effective means of control. In Europe, Himalayan balsam has been included since 2017 in the list of Invasive Alien Species of Union concern (the Union list). This implies that the species cannot be imported, cultivated, transported, commercialized, planted, or intentionally released into the environment in the whole of the European Union. Etymology The common names Himalayan balsam and kiss-me-on-the-mountain refer to the plant's native Himalayan mountains. Ornamental jewelweed refers to its cultivation as an ornamental plant. The specific epithet ''glandulifera'' is a compound word from ''glándula'' meaning 'small gland', and ''ferre'' meaning 'to bear'. Description It typically grows to high, with a soft gree ...

Heracleum Mantegazzianum
''Heracleum mantegazzianum'', commonly known as giant hogweed, is a monocarpic perennial herbaceous plant in the carrot family Apiaceae. ''H. mantegazzianum'' is also known as cartwheel-flower, giant cow parsley, giant cow parsnip, or hogsbane. In New Zealand, it is also sometimes called wild parsnip (not to be confused with ''Pastinaca sativa'') or wild rhubarb. Giant hogweed is native to the western Caucasus region of Eurasia. It was introduced to Britain as an ornamental plant in the 19th century, and has also spread to other areas in Western Europe, the United States, and Canada. Its close relatives, Sosnowsky's hogweed and Persian hogweed, have similarly spread to other parts of Europe. The sap of giant hogweed is phototoxic and causes phytophotodermatitis in humans, resulting in blisters and scars. These serious reactions are due to the furanocoumarin derivatives in the leaves, roots, stems, flowers, and seeds of the plant. Consequently, it is considered to be a ...
