This paper advances an hypothesis that the primary adaptive driver of seasonal migration is
maintenance of site fidelity to familiar breeding locations. We argue that seasonal migration …

Comparative genetic studies of non-model organisms are transforming rapidly due to major
advances in sequencing technology. A limiting factor in these studies has been the …

Many groups show higher species richness in tropical regions but the underlying causes
remain unclear. Despite many competing hypotheses to explain latitudinal diversity …

Plant diversity, like that of most other taxonomic groups, peaks in the tropics, where climatic
conditions are warm and wet, and it declines toward the temperate and polar zones as …

Aim The pattern of increasing biological diversity from high latitudes to the equator
[latitudinal diversity gradient (LDG)] has been recognized for> 200 years. Empirical studies …

Aim Understanding the evolution of the latitudinal diversity gradient (ie increase in species
diversity towards the tropics) is a prominent issue in ecology and biogeography …

Climate change may soon threaten much of global biodiversity. A critical question is: can
species undergo niche shifts of sufficient speed and magnitude to persist within their current …

Climatic niches are essential in determining where species can occur and how they will
respond to climate change. However, it remains unclear if climatic-niche evolution is similar …

Abstract The Indian Himalaya is characterized by high plant diversity and endemism levels.
Here, the genus Rhododendron is one of the largest flowering plant genera. The flowering of …

Differences in life-history traits between tropical and temperate lineages are often attributed
to differences in their climatic niche dynamics. For example, the more frequent appearance …
