Detailed explanation-1: -The latitudinal diversity gradient (LDG), usually defined as an increase in species richness from the poles towards the equator, is a striking ecological pattern that has fascinated biologists over centuries (Willig et al. 2003; Mittelbach et al. 2007).
Detailed explanation-2: -Species richness, or biodiversity, increases from the poles to the tropics for a wide variety of terrestrial and marine organisms, often referred to as the latitudinal diversity gradient. The latitudinal diversity gradient is one of the most widely recognized patterns in ecology.
Detailed explanation-3: -Biodiversity increases towards the equator because the equator has a favorable climate rich in nutrients and sunlight that promotes the development of microhabitats.
Detailed explanation-4: -A latitudinal biodiversity gradient (LBG) has been identified in almost all organisms that have been investigated, on land and in the sea. The gradient involves high species’ numbers near the equator (at low latitudes) and lower numbers of species at high latitudes.
