Respuesta :
The most plausible hypothesis to explain why species richness is higher in tropical than in temperate regions is that tropical regions generally have more available water and higher levels of solar radiation.
Why are there so many species in the tropics?
More species of plants, animals, and fungus may be found in any given area in tropical climates, and this concentration decreases as you travel away from the equator. The latitudinal diversity gradient is the name given to this phenomena.
The key takeaway from this is that species diversity rises with rising temperatures far more quickly than population size and NPP do. This suggests that the LDG cannot be fully explained by productivity alone. Instead, it implies that the LDG is mostly caused by relatively direct kinetic processes. The increased metabolic rates, ecological dynamics, and coevolutionary processes brought on by the higher temperatures in the tropics produce and sustain more biodiversity.
