Cladtertia Collaboinventa
''Cladtertia'' is a genus of placozoan discovered in 2022. The genus contains a single described species, ''Cladtertia collaboinventa'', although several other undescribed lineages are known. Its closest described relative is '' Hoilungia hongkongensis'', with whom it forms the order Hoilungea. ''Cladtertia'' is similar in morphology to most other placozoans, but genetically distinct from them. It has been found in warm tropical waters with low seasonal changes, ranging from 26°N to 25°S, where it occupies a distinct ecological niche compared to other placozoan lineages. Sexual reproduction through cross-fertilization has been observed in a strain of ''Cladtertia''. Etymology The genus name comes from Ancient Greek ''kládos'' (clade) and Latin ''tertius'' (the third), referring to its specimens previously being assigned to placozoan Clade III in literature. Biology ''Cladtertia'' is morphologically indistinguishable under light microscopy from other placozoans in the cla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Placozoan
Placozoa ( ; ) is a phylum of free-living (non-parasitic) marine invertebrates. They are blob-like animals composed of aggregations of cells. Moving in water by ciliary motion, eating food by Phagocytosis, engulfment, reproducing by Fission (biology), fission or budding, placozoans are described as "the simplest animals on Earth." Structural and molecular analyses have supported them as among the most basal animals, thus, constituting a primitive metazoan phylum. The first known placozoan, ''Trichoplax adhaerens'', was discovered in 1883 by the German zoologist Franz Eilhard Schulze (1840–1921).F. E. Schulze "''Trichoplax adhaerens'' n. g., n. s.", ''Zoologischer Anzeiger'' (Elsevier, Amsterdam and Jena) 6 (1883), p. 92. Describing the uniqueness, another German, Karl Gottlieb Grell (1912–1994), erected a new phylum, Placozoa, for it in 1971. Remaining a monotypic phylum for over a century, new species began to be added since 2018. So far, three other extant species have been ...

Mitochondrial Genome
Mitochondrial DNA (mtDNA and mDNA) is the DNA located in the mitochondria organelles in a eukaryotic cell that converts chemical energy from food into adenosine triphosphate (ATP). Mitochondrial DNA is a small portion of the DNA contained in a eukaryotic cell; most of the DNA is in the cell nucleus, and, in plants and algae, the DNA also is found in plastids, such as chloroplasts. Mitochondrial DNA is responsible for coding of 13 essential subunits of the complex oxidative phosphorylation (OXPHOS) system which has a role in cellular energy conversion. Human mitochondrial DNA was the first significant part of the human genome to be sequenced. This sequencing revealed that human mtDNA has 16,569 base pairs and encodes 13 proteins. As in other vertebrates, the human mitochondrial genetic code differs slightly from nuclear DNA. Since animal mtDNA evolves faster than nuclear genetic markers, it represents a mainstay of phylogenetics and evolutionary biology. It also permits traci ...

Panama
Panama, officially the Republic of Panama, is a country in Latin America at the southern end of Central America, bordering South America. It is bordered by Costa Rica to the west, Colombia to the southeast, the Caribbean Sea to the north, and the Pacific Ocean to the south. Its capital and largest city is Panama City, whose metropolitan area is home to nearly half of the country's over million inhabitants. Before the arrival of Spanish Empire, Spanish colonists in the 16th century, Panama was inhabited by a number of different Indigenous peoples of Panama, indigenous tribes. It Independence Act of Panama, broke away from Spain in 1821 and joined the Republic of Gran Colombia, a union of Viceroyalty of New Granada, Nueva Granada, Ecuador, and Venezuela. After Gran Colombia dissolved in 1831, Panama and Nueva Granada eventually became the Republic of Colombia. With the backing of the United States, Panama seceded from Colombia in 1903, allowing the construction of the Panama Ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Isla Iguana Wildlife Refuge
The Isla Iguana Wildlife Refuge is a 53-hectare wildlife reserve located 5 kilometers off the Los Santos Province on the Azuero Peninsula in Panama. The island has 13 hectares with a dry tropical rain forest and there are 40 more hectares of coral. Coral reefs that surround the island have over 17 species of corals and 347 species of fish. It is also possible to see octopus, moray eels and dolphins. Humpback whales come to the island and the shores of Panama's Pacific coast during the months of June or July through October to give birth and teach their calves to swim in the warm waters. Whale watching tours are popular during this season. The island also serves as a place where five species of sea turtles come to lay eggs during the months of April and September. Tours to Isla Iguana depart from Arenal Beach in Pedasi or from Mariabe, the town before Pedasi, which offers a shorter crossing time. History During World War II, the United States Army used the Isla Iguana Wildlife ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhodopidae
Rhodopidae is a family of sea slugs. Rhodopids are small, meiofaunal organisms with worm-like body plans that differ considerably from a typical gastropod body plan, to the point that ''Rhodope'' was at one point classified as a flatworm. They have no shell. Two genera are currently recognized within the family, ''Rhodope'' and '' Helminthope''. ''Helminthope'' has been described as the most worm-like gastropod. Etymology ''Rhodope'', the type genus of the family, is named for Rhodope, a figure in Greek mythology. Description Rhodopids have worm-like bodies with no appendages. They often have red, orange, or purple bands, in varying pattern depending on the species, though some species are entirely white. The species range in length from 1.5 to 8 mm, although they are capable of considerably contracting themselves. The length-to-width ratios of the body while extended to crawl is around 9 in ''Rhodope'' and 25 in ''Helminthope''. Their bodies contain spicules below the epidermi ...

Kewalo Marine Laboratory
Kewalo Basin is a commercial boat harbor that serves as home to some of Honolulu's commercial fishing fleet, and charter and excursion vessels that serve the Hawaii tourist market. Pre-European contact, the area was historically used for human sacrifice. The land was given to Ihu by Kamehameha I and inherited by his daughter Kamakeʻe and her husband Jonah Piikoi. On the ocean side of the harbor is a small beach park on the Honolulu waterfront, located adjacent to the larger Ala Moana Beach Park. This park is good for swimming, picnicking and sightseeing. It can be accessed from the corners of Ala Moana Boulevard and Ward Avenue.

Water Table
The water table is the upper surface of the phreatic zone or zone of saturation. The zone of saturation is where the pores and fractures of the ground are saturated with groundwater, which may be fresh, saline, or brackish, depending on the locality. It can also be simply explained as the depth below which the ground is saturated. The portion above the water table is the vadose zone. It may be visualized as the "surface" of the subsurface materials that are saturated with groundwater in a given vicinity. In coarse soils, the water table settles at the surface where the water Hydraulic head, pressure head is equal to the atmospheric pressure (where gauge pressure = 0). In soils where capillary action is strong, the water table is pulled upward, forming a capillary fringe. The groundwater may be from precipitation or from more distant groundwater flowing into the aquifer. In areas with sufficient precipitation, water infiltrates through pore spaces in the soil, passing through t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
