چکیده

Aim To utilize comprehensive geographical sampling and a new, multilocus dataset to re-examine the biogeography of spotted stream frogs (Hylarana signata complex) throughout Southeast Asia. To compare patterns of diversification among stream frog populations on land-bridge islands and oceanic islands and to re-evaluate a previous ‘dual-invasion’ hypothesis for the origins of endemic Philippine taxa.

The pattern and timing of diversification of Philippine endemic rodents: evidence from mitochondrial and nuclear gene sequences.

The 22 genera and 64 species of rodents (Muridae: Murinae) distributed in the Philippine Islands provide a unique opportunity to study patterns and processes of diversification in island systems. Over 90% of these rodent species are endemic to the archipelago, but the relative importance of dispersal from the mainland, dispersal within the archipelago, and in situ differentiation as explanation...

Island Populations of Physalaemus Pustulosus: History Influences Genetic Diversity and Morphology

Island populations are convenient models of large-scale evolutionary processes and provide natural replicates of evolution. Recently founded island populations also provide an opportunity to study populations derived from few individuals, and these populations, in particular, often show rapid diversification. Here we report morphological and molecular data for the túngara frog, Physalaemus pust...

Adaptive Radiation and Ecological Opportunity in Sulawesi and Philippine Fanged Frog (<italic>Limnonectes</italic>) Communities

Because island communities are derived from mainland communities, they are often less diverse by comparison. However, reduced complexity of island communities can also present ecological opportunities. For example, amphibian diversity on Sulawesi Island is lower than it is in the Philippines, but Sulawesi supports a surprising diversity of Sulawesi fanged frogs (Limnonectes). Here we examine mo...

PERMIAN-TRIASSIC BOUNDARY OF INDIAN SUBCONTINENT AND ITS INTERCONTINENTAL CORRELATION

The Permian-Triassic boundary in the Himalayas is reviewed and discussed in the light of palaeontologic and stratigraphic data collected during the past two and a half decades from Kashmir, Spiti and Nepal. The deposition of the Kuling Shales and their equivalents in different parts of the Himalayas was followed by shallowing and regression of the sea. Sedimentation was interrupted at the t...
