The apparent biotic affinities between the mainland and the island in the Western Ghats–Sri Lanka biodiversity hotspot have been interpreted as the result of frequent migrations during recent periods of low sea level. We show, using molecular phylogenies of two invertebrate and four vertebrate groups, that biotic interchange between these areas has been much more limited than hitherto assumed. Despite several extended periods of land connection during the past 500,000 years, Sri Lanka has… 

A brief overview of the Western Ghats - Sri Lanka biodiversity hotspot

The Western Ghats of India and Sri Lanka biodiversity hotspot is often regarded as one unit because of shared biogeographical history. However, recent studies suggest that certain faunal components,


The fauna and flora of Sri Lanka have generally been considered an extension of that of southern India, especially the southern Western Ghats, the range of mountains that borders the western littoral

Did biotic impoverishment facilitate phenomenal diversification in Sri Lanka

It is hypothesized that the degree of this past extinction was differential, with Sri Lanka experiencing a higher degree of impoverishment than Peninsular India, which created ecological opportunities and facilitated speciation in taxa that survived on the island or later reached the island.

Freshwater fish fauna of the Ashambu Hills landscape, southern Western Ghats, India, with notes on some range extensions

A systematic, updated checklist of freshwater fish species of the west-flowing drainages of the Ashambu (Agasthyamala) Hills landscape in the southern Western Ghats of Kerala, India is provided, with

Did southern Western Ghats of peninsular India serve as refugia for its endemic biota during the Cretaceous volcanism?

It is suggested that southern WG might have served as a refuge for Digitipes species during Cretaceous volcanism, and species from each of the biogeographic subdivisions within the WG would form distinct clades.

Endemism-based butterfly conservation: insights from a study in Southern Western Ghats, India

Background The Western Ghats, a biodiversity hotspot in India harbours a high percentage of endemic species due to its unique and diverse habitats. These species which cannot survive elsewhere due to

Sri Lankan snail diversity: faunal origins and future prospects

The maintenance of high levels of endemism and generation of high species diversity in a confined area through long periods is thought to be linked to the varied topography in Sri Lanka and the capacity for altitudinal faunal shifts in response to climate change.

High cryptic diversity of endemic Indirana frogs in the Western Ghats biodiversity hotspot

The results suggest the existence of multiple unrecognized cryptic lineages within Indirana, all of which are likely to have more narrow distribution ranges and lower abundances than the taxonomic units into which they are currently assigned.

Contributions of vulnerable hydrogeomorphic habitats to endemic plant diversity on the Kas Plateau, Western Ghats

Since botanically critical plateau habitats are generally small, dependent on seasonal monsoon moisture, and determined by drainage-related parameters that can be altered by anthropogenic activities, they are highly vulnerable.



Habitat values and endemicity in the vanishing rain forests of Sri Lanka

TROPICAL forests are among the most seriously threatened terrestrial environments, and while biologists and conservationists argue for preservation, the plunder continues virtually unabated1. In Sri

Rapid evolution to terrestrial life in Jamaican crabs

Molecular evidence is presented that Jamaican land crabs represent a single adaptive radiation from a marine ancestor that invaded terrestrial habitats only 4 million years ago and probably reflects the Mid-Tertiary inundation of that island.

Arthropods on islands: colonization, speciation, and conservation.

The literature on islands in the broadest sense is examined, whether surrounded by water or any other uninhabitable matrix) as it pertains to terrestrial arthropods, and the primary distinction between different island systems is "darwinian" islands (formed de novo) and "fragment" islands.

Biodiversity hotspots for conservation priorities

A ‘silver bullet’ strategy on the part of conservation planners, focusing on ‘biodiversity hotspots’ where exceptional concentrations of endemic species are undergoing exceptional loss of habitat, is proposed.

Freshwater fishes of Sri Lanka

It seems as though Konings conducted this expedition for a limited time period, and some of his surmised biological explanations suffer as a result, for example he claims that very few cichlids breed in Jan.-Feb.
