Erik Leonard Ekman
Erik Leonard Ekman was a Swedish botanist and explorer. Biography Erik Leonard Ekman was born into a low-income household with five children on October 14, 1883. Due to economic difficulties, the family moved to the central-Swedish town of Jönköping when he was eleven and a half. Here, while at school, his passion for botanical collecting started. He was awarded a bachelor's degree in 1907 at Lund University in southern Sweden and was offered free passage on a ship to Argentina with a Swedish shipping company. He spent three months in Misiones collecting plants, aided greatly by the local Swedish colony. While there, he was offered a position as the Regnellian amanuensis at the Swedish Museum of Natural History in Stockholm, which he gladly accepted. He started his service at the museum in 1908. Thanks to financial support from the Regnell fund, he was able to travel widely through Europe and study with many of the prominent botanists of the time. Ekman presented his doctora ...

Rupununi
The Rupununi is a region in the south-west of Guyana, bordering the Brazilian Amazon. The Rupununi river, also known by the local indigenous peoples as ''Raponani'', flows through the Rupununi region. The name Rupununi originates from the word ''rapon'' in the Makushi language, in which it means the black-bellied whistling duck found along the river. Geography The Rupununi River is one of the main tributaries of the Essequibo River and is located in southern Guyana. The river originates in the Kanuku Mountains, which are located in the Upper Takutu-Essequibo region. The Rupununi River flows near the Guyana-Brazil border, and eventually leads into the Essequibo River. Throughout the flood season, the river shares a watershed with the Amazon. During the rainy season it is connected to the Takutu River by the flooded Pirara Creek, draining the vast swamps of the Parima or Amaku Lake. The region surrounding the Rupununi river is composed of mainly savannah, wetlands, forest, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Poaceae Genera
Poaceae () or Gramineae () is a large and nearly ubiquitous family of monocotyledonous flowering plants commonly known as grasses. It includes the cereal grasses, bamboos and the grasses of natural grassland and species cultivated in lawns and pasture. The latter are commonly referred to collectively as grass. With around 780 genera and around 12,000 species, the Poaceae is the fifth-largest plant family, following the Asteraceae, Orchidaceae, Fabaceae and Rubiaceae. The Poaceae are the most economically important plant family, providing staple foods from domesticated cereal crops such as maize, wheat, rice, barley, and millet as well as feed for meat-producing animals. They provide, through direct human consumption, just over one-half (51%) of all dietary energy; rice provides 20%, wheat supplies 20%, maize (corn) 5.5%, and other grains 6%. Some members of the Poaceae are used as building materials (bamboo, thatch, and straw); others can provide a source of biofuel, primaril ...

Chloridoideae
Chloridoideae is one of the largest subfamilies of grasses, with roughly 150 genera and 1,600 species, mainly found in arid tropical or subtropical grasslands. Within the PACMAD clade, their sister group are the Danthonioideae. The subfamily includes widespread weeds such as Bermuda grass (''Cynodon dactylon'') or goosegrass (''Eleusine indica''), but also millet species grown in some tropical regions, namely finger millet (''Eleusine coracana'') and teff (''Eragrostis tef''). With the exception of some species in ''Ellisochloa'' and Eleusine indica, most of the subfamily's species use the C4 photosynthetic pathway. The first evolutionary transition from C3 to C4 photosynthesis in the grasses probably occurred in this subfamily, around 32 to 25 million years ago in the Oligocene. Phylogeny Relationships of tribes in the Chloridoideae according to a 2017 phylogenetic classification, also showing the Danthonioideae as sister group: The following genera have not been assigned t ...
