Johann Friedrich Von Brandt
Johann Friedrich von Brandt (25 May 1802 – 15 July 1879) was a German-Russian natural history, naturalist, who worked mostly in Russia. Brandt was born in Jüterbog and educated at a Gymnasium (school), gymnasium in Wittenberg and the Humboldt University of Berlin, University of Berlin. In 1831 he emigrated to Russia, and soon was appointed director of the Zoological Museum of the St Petersburg Academy of Sciences. Brandt encouraged the collection of native animals, many of which were not represented in the museum. Many specimens began to arrive from the expeditions of Nikolai Alekseevich Severtzov, Severtzov, Nikolai Przhevalsky, Przhevalsky, Aleksandr Fyodorovich Middendorf, Middendorff, Leopold von Schrenck, Schrenck and Gustav Radde. He described several birds collected by Russian explorers off the Pacific Coast of North America, including Brandt's cormorant, red-legged kittiwake and spectacled eider. As a paleontologist, Brandt ranks among the best. He was also an entomo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea Cucumber
Sea cucumbers are echinoderms from the class Holothuroidea (). They are marine animals with a leathery skin and an elongated body containing a single, branched gonad. Sea cucumbers are found on the sea floor worldwide. The number of holothurian () species worldwide is about 1,717, with the greatest number being in the Asia-Pacific region. Many of these are gathered for human consumption and some species are cultivated in aquaculture systems. The harvested product is variously referred to as '' trepang'', ''namako'', ''bêche-de-mer'', or ''balate''. Sea cucumbers serve a useful role in the marine ecosystem as they help recycle nutrients, breaking down detritus and other organic matter, after which bacteria can continue the decomposition process. Like all echinoderms, sea cucumbers have an endoskeleton just below the skin, calcified structures that are usually reduced to isolated microscopic ossicles (or sclerietes) joined by connective tissue. In some species these can sometim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monterey Bay
Monterey Bay is a bay of the Pacific Ocean located on the coast of the U.S. state of California, south of the San Francisco Bay Area and its major city at the south of the bay, San Jose. San Francisco itself is further north along the coast, by about 75 miles, accessible via Highway 1 and Highway 280. Santa Cruz is located at the north end of the bay, and Monterey is on the Monterey Peninsula at the south end. The "Monterey Bay Area" is a local colloquialism sometimes used to describe the whole of the Central Coast communities of Santa Cruz and Monterey counties. Toponymy The first European to discover Monterey Bay was Juan Rodríguez Cabrillo on November 16, 1542, while sailing northward along the coast on a Spanish naval expedition. He named the bay ''Bahía de los Pinos'', probably because of the forest of pine trees first encountered while rounding the peninsula at the southern end of the bay. Cabrillo's name for the bay was lost, but the westernmost point of the penin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Point Arena-Stornetta Public Lands
The California Coastal National Monument is located along the entire coastline of the U.S. state of California. This monument ensures the protection of all islets, reefs and rock outcroppings along the coast of California within of shore along the entire long coastline. Conservative estimates are for at least 20,000 such outcroppings. The monument was created by Bill Clinton via Presidential proclamation on January 11, 2000, with the authority in section two of the Antiquities Act of 1906. , the monument has expanded to . The U.S. Bureau of Land Management, an agency of the U.S. Department of the Interior that manages the monument, has developed gateways in cooperation with other agencies along the California coast to introduce the monument to the public. These include the Trinidad, Point Arena, Fort Bragg-Mendocino, Pigeon Point Lighthouse, Piedras Blancas State Marine Reserve and Marine Conservation Area, and the Palos Verdes Peninsula.

Alga
Algae (; singular alga ) is an informal term for a large and diverse group of photosynthetic eukaryotic organisms. It is a polyphyletic grouping that includes species from multiple distinct clades. Included organisms range from unicellular microalgae, such as ''Chlorella,'' ''Prototheca'' and the diatoms, to multicellular forms, such as the giant kelp, a large brown alga which may grow up to in length. Most are aquatic and autotrophic (they generate food internally) and lack many of the distinct cell and tissue types, such as stomata, xylem and phloem that are found in land plants. The largest and most complex marine algae are called seaweeds, while the most complex freshwater forms are the ''Charophyta'', a division of green algae which includes, for example, ''Spirogyra'' and stoneworts. No definition of algae is generally accepted. One definition is that algae "have chlorophyll ''a'' as their primary photosynthetic pigment and lack a sterile covering of cells around t ...

Intertidal
The intertidal zone, also known as the foreshore, is the area above water level at low tide and underwater at high tide (in other words, the area within the tidal range). This area can include several types of Marine habitat, habitats with various species of Marine life, life, such as seastars, Sea urchin, sea urchins, and many species of coral with regional differences in biodiversity. Sometimes it is referred to as the ''littoral zone'' or ''shore, seashore'', although those can be defined as a wider region. The well-known area also includes steep rocky Cliff, cliffs, sandy Beach, beaches, Bog, bogs or wetlands (e.g., vast Mudflat, mudflats). The area can be a narrow strip, as in Pacific island, Pacific islands that have only a narrow tidal range, or can include many meters of shoreline where shallow beach slopes interact with high tidal excursion. The peritidal zone is similar but somewhat wider, extending from above the highest tide level to below the lowest. Organisms in t ...

INaturalist
iNaturalist is a social network of naturalists, citizen scientists, and biologists built on the concept of mapping and sharing observations of biodiversity across the globe. iNaturalist may be accessed via its website or from its mobile applications. , iNaturalist users had contributed approximately 115,651,000 observations of plants, animals, fungi, and other organisms worldwide, and around 245,700 users were active in the previous 30 days. iNaturalist describes itself as "an online social network of people sharing biodiversity information to help each other learn about nature", with its primary goal being to connect people to nature. Although it is not a science project itself, iNaturalist is a ''platform'' for science and conservation efforts, providing valuable open data to research projects, land managers, other organizations, and the public. It is the primary application for crowd-sourced biodiversity data in places such as Mexico, southern Africa, and Australia, and the ...

Dendrochirotida
Dendrochirotida are an order of sea cucumbers. Members of this order have branched tentacles and are suspension feeders. Examples include '' Thyonella'' and '' Cucumaria''. Characteristics Holothurians in this order are characterised by ten to thirty much branched tentacles which are sometimes digitate. They also have ring structures composed of ten calcareous plates circling the pharynx. They have both retractor and introvert muscles which means they can retract the tentacles into the mouth when not feeding. The body wall is either firm with large ossicles or of a soft consistency with few ossicles. In some genera the animals attach themselves to hard surfaces but in others they burrow into soft sediments. Prey is captured by the sticky tentacles and transferred to the mouth. The larvae are lecithotrophic, not feeding on plankton but surviving only on materials already present in the eggs until they settle and become juveniles. Taxonomy Order: Dendrochirotida * family Cucumariida ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
