Dollabarat
The Dollabarat Reef is a shoal situated 5 km (3 nautical miles) south-southeast of the Formigas Islets on the Formigas Bank in the Azores archipelago. History The reef is named after Pierre Dollabarats, Basque captain of the ship ''Maria de Sebourre'', who accidentally discovered the reef when his small boat wrecked on it on 7 March 1788. Since 16 June 2008, Dollabarat Reef and the neighboring Formigas Islets have been recognized as a Ramsar Convention wetland under the name ''Ilhéus das Formigas e Recife Dollabarat'' (reference number 1804). Geography The Dollabarat Reef is part of the Formigas Islets Nature Reserve which covers .Tomaz Dentinho, João Lima & Ana Tavares (2000), p.2 Around the Formigas Reserve, including the Dollabarat, sea cliffs fall rapidly between , although gently to the north and south. The gradient around the Dollabarat is less accentuated. The highest point is below sea level. Dollabarat Reef is one of the higher parts of the Formigas Ban ...

Formigas Islets
The Formigas Islets ( pt, Ilhéus das Formigas ; literally, ''Islets of the Ants''), sometimes referred to as the Formigas Bank, are a group of uninhabited rocky outcroppings in the eastern group of the Azores archipelago, an autonomous region of Portugal. The bank is located northeast of Santa Maria and southeast of São Miguel, covering a surface area of approximately . In the same area is the submerged Dollabarat Reef. The only structure on the islets is a lighthouse located on Formigão (''Big Ant''), the largest islet. History The Formigas were discovered by Portuguese explorers Diogo de Silves and Gonçalo Velho Cabral in 1431 during their journey to Madeira. The islets were neglected due to the contemporaneous discovery of the neighboring inhabitable islands of Santa Maria and São Miguel. In the 16th century, Portuguese chronicler Gaspar Frutuoso reported on the Formigas' rich marine life. The Formigas served as both an aid and hindrance to navigation from their di ...

Islands Of The Azores
An island or isle is a piece of subcontinental land completely surrounded by water. Very small islands such as emergent land features on atolls can be called islets, skerries, cays or keys. An island in a river or a lake island may be called an eyot or ait, and a small island off the coast may be called a holm. Sedimentary islands in the Ganges Delta are called chars. A grouping of geographically or geologically related islands, such as the Philippines, is referred to as an archipelago. There are two main types of islands in the sea: continental islands and oceanic islands. There are also artificial islands (man-made islands). There are about 900,000 official islands in the world. This number consists of all the officially-reported islands of each country. The total number of islands in the world is unknown. There may be hundreds of thousands of tiny islands that are unknown and uncounted. The number of sea islands in the world is estimated to be more than 200,000. The t ...

Ponta Delgada
Ponta Delgada (; ) is the largest municipality (''concelho'') and economic capital of the Autonomous Region of the Azores in Portugal. It is located on São Miguel Island, the largest and most populous in the archipelago. As of 2021, it has 67,287 inhabitants, in an area of . There are 17,629 residents in the three central civil parishes that comprise the historical city: São Pedro, São Sebastião, and São José.

University Of The Azores
The University of the Azores (Portuguese: ''Universidade dos Açores''), or commonly abbreviated as ''UAc'', is the only public university in the Autonomous Region of the Azores. It was founded on January 9, 1976, two years after the Carnation Revolution that ended several decades of dictatorship in Portugal, but before the Portuguese Third Republic was institutionalized, along with the Region's Autonomy. The university is a public institution dependent on the Ministry of Science, Technology and Higher Education and was established in order to advance sustainable development and higher education in the Azores. History The establishment of the University of the Azores developed from a period of autonomous politics related to separatist movements that developed in the second half of 1975. Although not completely responsible, the events following the Carnation Revolution provided the conditions necessary for the creation of the university. Due to a level of academic disorder on the ...

Laminaria
''Laminaria'' is a genus of brown seaweed in the order Laminariales (kelp), comprising 31 species native to the north Atlantic and northern Pacific Oceans. This economically important genus is characterized by long, leathery laminae and relatively large size. Some species are called Devil's apron, due to their shape, or sea colander, due to the perforations present on the lamina. Others are referred to as ''tangle''. ''Laminaria'' form a habitat for many fish and invertebrates. The life cycle of ''Laminaria'' has heteromorphic alternation of generations which differs from '' Fucus''. At meiosis the male and female zoospores are produced separately, then germinate into male and female gametophytes. The female egg matures in the oogonium until the male sperm fertilizes it. Life-Cycle: The most apparent form of ''Laminaria'' is its sporophyte phase, a structure composed of the holdfast, the stipe, and the blades. While it spends its time predominately in the sporophyte pha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cystoseira
''Cystoseira'' is a genus of brown algae in the order Fucales. Description ''Cystoseira'' is characterized by highly differentiated basal and apical regions and the presence of catenate pneumatocysts (air-vesicles). In ''Cystoseira'' old plants have an elongated main axis, and in time the primary laterals become proportionally elongated. Their lower parts are strongly flattened into ‘foliar expansions’ or basal leaves. Fertile regions which bear conceptacles are known as receptacles. These are normally found at the tips of the branches. Their basal and apical regions are highly differentiated. They have catenate pnuematocysts (air vesicles). The aerocyst or air vesicles keep the organism erect, by causing it to float in strong currents. Distribution ''Cystoseira'' is one of the most widely distributed genera of the Fucales order and provides an essential habitat for many epiphytes, invertebrates, and fish. ''Cystoseira'' is found mostly in temperate regions of the Northern He ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Seaweed
Seaweed, or macroalgae, refers to thousands of species of macroscopic, multicellular, marine algae. The term includes some types of ''Rhodophyta'' (red), ''Phaeophyta'' (brown) and ''Chlorophyta'' (green) macroalgae. Seaweed species such as kelps provide essential nursery habitat for fisheries and other marine species and thus protect food sources; other species, such as planktonic algae, play a vital role in capturing carbon, producing at least 50% of Earth's oxygen. Natural seaweed ecosystems are sometimes under threat from human activity. For example, mechanical dredging of kelp destroys the resource and dependent fisheries. Other forces also threaten some seaweed ecosystems; a wasting disease in predators of purple urchins has led to a urchin population surge which destroyed large kelp forest regions off the coast of California. Humans have a long history of cultivating seaweeds for their uses. In recent years, seaweed farming has become a global agricultural practice, p ...

Dolphin
A dolphin is an aquatic mammal within the infraorder Cetacea. Dolphin species belong to the families Delphinidae (the oceanic dolphins), Platanistidae (the Indian river dolphins), Iniidae (the New World river dolphins), Pontoporiidae (the brackish dolphins), and the extinct Lipotidae (baiji or Chinese river dolphin). There are 40 extant species named as dolphins. Dolphins range in size from the and Maui's dolphin to the and orca. Various species of dolphins exhibit sexual dimorphism where the males are larger than females. They have streamlined bodies and two limbs that are modified into flippers. Though not quite as flexible as seals, some dolphins can briefly travel at speeds of per hour or leap about . Dolphins use their conical teeth to capture fast-moving prey. They have well-developed hearing which is adapted for both air and water. It is so well developed that some can survive even if they are blind. Some species are well adapted for diving to great de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
