A lagoon is a shallow body of water separated from a larger body of water by reefs, barrier ... In some languages the word for a lagoon is simply a type of lake. There three types pf natural lagoons: coastal, atoll and river-mouth (often also coastal). The water in a lagoon is almost always brackish

Methane-fueled Ecosystems (Researchers have discovered a methane-fueled ecosystem that feeds bacteria in the underground rivers and flooded caves of Mexico's Yucatan Peninsula)

 The ecology of nautiluses: are exclusively opportunistic scavengers, and readily and commonly eat arthropod molts, which all contain surprising amount of organic integuments holding the calcareous or chitinous parts together. We have also observed nautiluses to swim slowly forward with one or more tentacles gently trawling through the upper millimeters of soft mud bottom. nautiluses will excavate meat from sediment that is buried up to 25 mm below the surface: it blows sediment away with exhalation of the hyponome. In this way the sediment is recirculated and reused.

The idea of the economy of nature (protoecology) was taken up by very few nature disciples only to a very limited extent. The tradition of developing botanical science came to be dominated by species description, systematics, and a highly comprehensive mapping of flora and fauna. Why this was the case deserves close attention from the point of view of the history of science

Queen Elizabeth National Park (is Uganda’s most popular tourist destination. The park’s diverse ecosystems, which include sprawling savanna, shady, humid forests, sparkling lakes and fertile wetlands, make it the ideal habitat for classic big game, ten primate species including chimpanzees and over 600 species of birds. The Queen Elizabeth National Park has been designated a Biosphere Reserve for Humanity under UNESCO auspices)

This park is famous for its tree climbing lions................here's them taking a "cat nap"...................

Raymond Laurel Lindeman (1915 – June 29, 1942) was an ecologist whose graduate research is often credited with being a seminal study in field of ecosystem ecology. Lindeman completed his PhD at the University of Minnesota with his thesis work being concerned with the history and ecological dynamics of Cedar Bog Lake, located in what is known today as the University of Minnesota's Cedar Creek Ecosystem Science Reserve in central Minnesota.

Socotra (is one of the most biodiversity rich and distinct islands in the world and hosts one of the oldest ecosystems on Earth. Located in the Indian Ocean, the Socotra ecosystem is uniquely characterized by incredible rare species of endemic flora, fauna and marine biodiversity, a third of which are found nowhere else on the Earth. Socotra is often dubbed as the “Galapagos of the Indian Ocean” because of its exceptionally high level of biodiversity and endemism in its terrestrial and marine ecosystem. This distinct “living museum” of botanical and zoological treasure sits at the crossroads of three biogeographical regions and includes many unique endemic floras and faunas, including some varieties of plant which are more than 20 million years old. Socotra’s biodiversity remained resilient for centuries, however, the last two decades have threatened the ecosystem for many reasons including habitat fragmentation, degradation of woodlands, adverse climatic changes, cyclones, cattle overgrazing, unsustainable development, increased tourism, negative influence on marine wildlife, limited conservation resources, as well as current political instability)

Not a big fan of spiders but this one found on the island is cool looking, it's called a Blue Baboon........

Tunnel Enhances Population Viability in an ecosystem. Roads and traffic are pervasive components of landscapes throughout the world: they cause wildlife mortality, disrupt animal movements, and increase the risk of extinction
