Hippopotamuses In Colombia
Hippopotamuses are an introduced species in Colombia. Four hippopotamuses were kept by Pablo Escobar in the late 1970s, and upon his death in 1993 they were allowed to wander his unattended estate. By 2019 their population had grown to approximately one hundred individuals, causing concerns they may harm the native flora and fauna in the area; as well as posing significant threat to human population in the area. History In the late 1970s, Colombian drug lord Pablo Escobar kept four hippopotamuses in a private menagerie at his residence in Hacienda Nápoles, east of Medellín, Colombia. They were deemed too difficult to seize and move after Escobar's death, and hence left on the untended estate. By 2007, the animals had multiplied to 16 and had taken to roaming the area for food in the nearby Magdalena River. In early 2014, there were reported to be 40 hippopotamuses in Puerto Triunfo, Antioquia. The estimated population in December 2019 was around 90–120, with their range cov ...

West Indian Manatee
The West Indian manatee (''Trichechus manatus''), also known as the North American manatee, is a large, aquatic mammal native to warm coastal areas of the Caribbean, from the eastern US to northern Brazil. Living alone or in herds, it feeds on underwater plants and uses its whiskers to navigate. It is divided into two endangered subspecies, the Florida manatee (''T. m. latirostris'') in the US and the Antillean manatee (''T. m. manatus'') in the Caribbean, both of which face pressure from habitat loss, pollution, and other human activity. The West Indian manatee is the largest of the sirenians (order Sirenia), a group of large aquatic mammals that includes the dugong, other manatees, and the extinct Steller's sea cow. Manatees are herbivores, have developed vocal communication abilities, and are covered in highly sensitive whiskers (called vibrissae) that are used for feeding and navigation. In breeding season, several males form mating herds around an individual female; on aver ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The Grand Tour
''The Grand Tour'' is a British motoring television series, created by Jeremy Clarkson, Richard Hammond, James May and Andy Wilman, made for Amazon exclusively for its online streaming service Amazon Prime Video, and premiered on 18 November 2016. The programme was conceived in the wake of the departure of Clarkson, Hammond, May and Wilman from the BBC series ''Top Gear'' and was originally contracted with 36 episodes over three years. When the programme was launched, it followed a similar format to that of ''Top Gear'' between 2016 and 2019, including car reviews and timed laps, motoring challenges and races, studio segments, and celebrity guests, with the team using a studio within a large tent during this time; in its first series, the tent was located at different locations across the globe, before taking a fixed site within the Cotswolds. Episodes were released weekly to Amazon Prime Video accounts, and repeats of the first series were made available on traditional broa ...

Ecotourism
Ecotourism is a form of tourism involving responsible travel (using sustainable transport) to natural areas, conserving the environment, and improving the well-being of the local people. Its purpose may be to educate the traveler, to provide funds for ecological conservation, to directly benefit the economic development and political empowerment of local communities, or to foster respect for different cultures and for human rights. Since the 1980s, ecotourism has been considered a critical endeavor by environmentalists, so that future generations may experience destinations relatively untouched by human intervention. Ecotourism may focus on educating travelers on local environments and natural surroundings with an eye to ecological conservation. Some include in the definition of ecotourism the effort to produce economic opportunities that make conservation of natural resources financially possible. Generally, ecotourism deals with interaction with biotic components of the natura ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Toxodon
''Toxodon'' (meaning "bow tooth" in reference to the curvature of the teeth) is an extinct genus of South American mammals from the Late Miocene to early Holocene epochs (Mayoan to Lujanian in the SALMA classification) (about 11.6 million to 11,000 years ago). It is a member of Notoungulata, one of several now extinct orders of hoofed mammals indigenous to South America distinct from living perissodactyls and artiodactyls. It was among the largest and last members of its order, and was probably the most common large hoofed mammal in South America of its time. Taxonomy ''Toxodon'' was one of the last members of Notoungulata, a group of ungulates that had been part of the fauna of South America since the Paleocene. ''Toxodon'' was a member of Toxodontidae a large bodied group including similar, vaguely rhinoceros like forms. Charles Darwin was one of the first to collect ''Toxodon'' fossils, after paying 18 pence for a ''T. platensis'' skull from a farmer in Uruguay ...

Pleistocene Rewilding
Pleistocene rewilding is the advocacy of the reintroduction of extant Pleistocene megafauna, or the close ecological equivalents of extinct megafauna. It is an extension of the conservation practice of rewilding, which involves reintroducing species to areas where they became extinct in recent history (hundreds of years ago or less). Towards the end of the Pleistocene era (roughly 13,000 to 10,000 years ago), nearly all megafauna of Eurasia, Australia, and South/North America, dwindled towards extinction, in what has been referred to as the Quaternary extinction event. With the loss of large herbivores and predator species, niches important for ecosystem functioning were left unoccupied. In the words of the biologist Tim Flannery, "ever since the extinction of the megafauna 13,000 years ago, the continent has had a seriously unbalanced fauna". This means, for example, that the managers of national parks in North America have to resort to culling to keep the population of ungula ...

Algae Bloom
An algal bloom or algae bloom is a rapid increase or accumulation in the population of algae in Fresh water, freshwater or Ocean, marine water systems. It is often recognized by the discoloration in the water from the algae's pigments. The term ''algae'' encompasses many types of aquatic Photosynthesis, photosynthetic organisms, both macroscopic multicellular organisms like seaweed and microscopic unicellular organisms like cyanobacteria. ''Algal bloom'' commonly refers to the rapid growth of microscopic unicellular algae, not macroscopic algae. An example of a macroscopic algal bloom is a kelp forest. Algal blooms are the result of a nutrient, like nitrogen or phosphorus from various sources (for example fertilizer runoff or other forms of nutrient pollution), entering the aquatic system and causing excessive growth of algae. An algal bloom affects the whole ecosystem. Consequences range from the benign feeding of higher trophic levels to more harmful effects like blocking s ...

Cyanobacteria
Cyanobacteria (), also known as Cyanophyta, are a phylum of gram-negative bacteria that obtain energy via photosynthesis. The name ''cyanobacteria'' refers to their color (), which similarly forms the basis of cyanobacteria's common name, blue-green algae, although they are not usually scientifically classified as algae. They appear to have originated in a freshwater or terrestrial environment. Sericytochromatia, the proposed name of the paraphyletic and most basal group, is the ancestor of both the non-photosynthetic group Melainabacteria and the photosynthetic cyanobacteria, also called Oxyphotobacteria. Cyanobacteria use photosynthetic pigments, such as carotenoids, phycobilins, and various forms of chlorophyll, which absorb energy from light. Unlike heterotrophic prokaryotes, cyanobacteria have internal membranes. These are flattened sacs called thylakoids where photosynthesis is performed. Phototrophic eukaryotes such as green plants perform photosynthesis in plast ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
