Nematanthus is a genus of flowering plants in the family Gesneriaceae. All of its species are endemic to Brazil. [1] Compared to other gesneriads, Nematanthus has leaves that are small, succulent, and hard-surfaced. The plant has a trailing, branching, and spreading habit; it is generally an epiphyte in
The project raises the saltwater fish species red drum alongside salt-loving halophyte plants, sea purslane and saltwort.. The plants are on a 2 month harvest cycle, and sold via local farmers’ markets. The fish production is on a 9-12 months harvest cycle. They are distributed through Florida-based wholesalers.
The plants use nitrogen and phosphorus produced from fish waste as fertilizer, while simultaneously cleaning the water as it grows. The water can then be reused by the aquaculture farmers, and the duckweed, which has a 35-42% protein content, can be harvested as a source of sustainable plant-based protein .
Most oceanic species (78 per cent, or 44 per cent of all fish species), live near the shoreline. These coastal fish live on or above the relatively shallow continental shelf. Only 13 per cent of all fish species live in the open ocean, off the shelf. Of these, 1 per cent are epipelagic, 5 per cent are pelagic, and 7 per cent are deep water. [16]
In 1995, salmon had a FIFO ratio of 7.5 (meaning 7.5 kilograms of wild fish feed were required to produce one kilogram of salmon); by 2006 the ratio had fallen to 4.9. [102] Additionally, a growing share of fish oil and fishmeal come from residues (byproducts of fish processing), rather than dedicated whole fish. [ 103 ]
The Caño Cristales river in Colombia is famous for the bright red Rhyncholacis clavigera (syn. Macarenia clavigera), a species only found in Serranía de la Macarena [10] The Podostemaceae are related to the families Clusiaceae , Hypericaceae (the St. John's wort family, which is sometimes treated as a subfamily of Clusiaceae), and Bonnetiaceae .
Botany, also called plant science or phytology, is the branch of natural science and biology studying plants, especially their anatomy, taxonomy, and ecology. [1] A botanist , plant scientist or phytologist is a scientist who specialises in this field.
Some species-focused databases attempt to compile comprehensive data about particular species , while others focus on particular species attributes, such as checklists of species in a given area (FEOW) or the conservation status of species (CITES or IUCN Red List). Nomenclators act as summaries of taxonomic revisions and set a key between ...
