Amazonian rainforests are among the most species-rich terrestrial habitats on Earth. The aim of this study was to analyze phylogenetic diversity (PD) patterns of orchid bee assemblages along a ...

Aims (i) To describe at the level of local communities latitudinal gradients in the species richness of different families of New World bats and to explore the generality of such gradients. (ii) To ...

A new study led by Prof. Chen Hongsong from the Institute of Subtropical Agriculture of the Chinese Academy of Sciences has revealed that calcium-rich bedrock can reshape the latitudinal diversity ...

Why are there so many species in the tropics? For centuries, scientists have been seeking for the causes of the latitudinal gradient in species diversity - a pattern that has been documented for most ...

Abstract. We report that a latitudinal cline in intertidal food distribution is associated with the nonbreeding distribution of the Western Sandpiper (Calidris mauri). This novel result is the first ...

UNDER EMBARGO UNTIL 16:00 GMT / 11:00 ET WEDNESDAY 15 FEBRUARY 2023. Today, species richness peaks in equatorial regions but until now there has been no clear explanation for this. By analysing fossil ...

Life on Earth is most diverse at the equator. This pattern, where species biodiversity increases as we move through the tropics towards the equator, is seen on land and in the oceans, and has been ...

Researchers have used nearly half a million fossils to solve a 200-year-old scientific mystery: why the number of different species is greatest near the equator and decreases steadily towards polar ...
