The paleo river systems of the Sunda Shelf are vast submerged river systems that extend present-day river systems and may be interpreted to follow topographic lows in a down-slope direction. During the driest period of the Pleistocene era (about 17,000 years BP) some four distinct catchment areas form the Malacca, Siam and Sunda river systems. [10]
The Sahul Shelf and the Sunda Shelf today. The area in between is called "Wallacea"Sundaland [1] (also called Sundaica or the Sundaic region) is a biogeographical region of Southeast Asia corresponding to a larger landmass that was exposed throughout the last 2.6 million years during periods when sea levels were lower.
Glacial phenomena on Mount Kinabalu as evidence of the snow fall and ice-capped mountains in the hot equatorial region [and ice sheet on lowland areas in the temperate regions described in many other papers]. The effects of LGM were for the Last Glacial Maximum, temperatures 4–7 °C (39–45 °F) lower than at present are recorded.
Wallace's Line is visible geographically when the continental shelf contours are examined. It figures as a deep-water channel that separates the southeastern edge of the Sunda Shelf from the Sahul Shelf. The Sunda Shelf links Borneo, Bali, Java, and Sumatra underwater to the mainland of southeastern Asia, while the Sahul Shelf connects ...
The avian endemism has been shaped by the island's geological history. Borneo sits on a continental shelf. During glacial periods, when water levels were lower, Borneo was linked with other islands on the shelf and with the Malay Peninsula in a large landmass known as Sundaland. This allowed bird species to move freely throughout the region ...
Within ice ages, there exist periods of more severe glacial conditions and more temperate conditions, referred to as glacial periods and interglacial periods, respectively. The Earth is currently in such an interglacial period of the Quaternary glaciation, with the Last Glacial Period of the Quaternary having ended approximately 11,700 years ago.
A continental shelf is a portion of a continent that is submerged under an area of relatively shallow water, known as a shelf sea. Much of these shelves were exposed by drops in sea level during glacial periods. The shelf surrounding an island is known as an "insular shelf."
A glacial period (alternatively glacial or glaciation) is an interval of time (thousands of years) within an ice age that is marked by colder temperatures and glacier advances. Interglacials, on the other hand, are periods of warmer climate between glacial periods. The Last Glacial Period ended about 15,000 years ago. [1]
