To determine the historical dynamics of colonization and whether the relative timing of colonization predicts diversification rate in the species‐rich, murine rodent communities of Indo‐Australia. 

Dietary morphology of two island-endemic murid rodent clades is consistent with persistent, incumbent-imposed competitive interactions

This work illustrates that incumbency has the potential to have a profound influence on the ecomorphological diversity of colonizing lineages at the island scale even when the traits in question are evolving at similar rates among independently colonizing clades.

Mitogenomes Reveal Multiple Colonization of Mountains by Rattus in Sundaland

Abstract Tropical mountains are cradles of biodiversity and endemism. Sundaland, tropical Southeast Asia, hosts 3 species of Rattus endemic to elevations above 2000 m with an apparent convergence in

When adaptive radiations collide: Different evolutionary trajectories between and within island and mainland lizard clades

It is shown that extensive continental radiations can result from island ancestors and that the incumbent and invading mainland clades achieve their ecological and morphological disparity in very different ways.

Historical biogeography of Tetrastigma (Vitaceae): Insights into floristic exchange patterns between Asia and Australia

Biodiversity exchanges across the Malesian region, linking the distinct biotas of Asia and Australia, have long attracted the curiosity of biologists. Tetrastigma (Vitaceae) has a wide distribution

Molecular Evolution of Ecological Specialisation: Genomic Insights from the Diversification of Murine Rodents

The results suggest a link between positive selection and derived ecological phenotypes, and highlight specific genes and general functional categories that may have played an integral role in the extensive and rapid diversification of murine rodents.

Trait-specific patterns of community ecospace occupancy in an insular mammal radiation

Communities that vary in the richness of closely related species but occupy similar environments provide a powerful system to investigate how trait variation and species richness interact to fill

Crossing Lydekker's Line: Northern Water Dragons (Tropicagama temporalis) Colonized the Mollucan Islands of Indonesia from New Guinea

Abstract Wallace's and Lydekker's Lines both describe important biogeographic barriers in the Indo-Australian Archipelago, with Wallace's Line demarcating the boundary of the Greater Sunda Shelf and

Evolutionary history of Sundaland shrews (Eulipotyphla: Soricidae: Crocidura) with a focus on Borneo

A phylogeny of all recognized species of Sundaland Crocidura is generated and it is shown that most speciation events took place during the Pleistocene, prior to the inundation of the Sunda Shelf around 400 000 years ago.

Locomotory mode transitions alter phenotypic evolution and lineage diversification in an ecologically rich clade of mammals

It is suggested that versatile, generalist forms act as seeds of species diversity and morphological specialization, which together build ecologically diverse radiations.



How small an island? Speciation by endemic mammals (Apomys, Muridae) on an oceanic Philippine island

To investigate the influence of oceanic island area on speciation by small mammals, in the context of other land vertebrates, the objective is to establish a database of small mammal speciation in the Southern Ocean.

Testing diversification models of endemic Philippine forest mice (Apomys) with nuclear phylogenies across elevational gradients reveals repeated colonization of isolated mountain ranges

The extent of diversification in an endemic clade of small mammals on a large oceanic island is documented and whether speciation occurred primarily along isolated elevational gradients or among montane areas is tested.

Evolutionary history of the thicket rats (genus Grammomys) mirrors the evolution of African forests since late Miocene

Grammomys are mostly arboreal rodents occurring in forests, woodlands and thickets throughout sub‐Saharan Africa. We investigated whether the divergence events within the genus follow the existing

Biogeographical modules and island roles: a comparison of Wallacea and the West Indies

Aim  In order to advance our understanding of the assembly of communities on islands and to elucidate the function of different islands in creating regional and subregional distribution patterns, we

Diversification rates of the “Old Endemic” murine rodents of Luzon Island, Philippines are inconsistent with incumbency effects and ecological opportunity

The results suggest that ecological incumbency has not played an important role in determining lineage diversification among Luzon murines, despite sympatric occurrence by constituent species within each lineage, and a substantial head start for the primary colonists.

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

The results suggest that most of the diversification of Philippine murines took place within the archipelago, and that combination of mitochondrial and nuclear data to estimate relatively ancient divergence times can severely compromise those estimates, even when specific methods that account for rate heterogeneity among genes are employed.

Macroevolution of hyperdiverse flightless beetles reflects the complex geological history of the Sunda Arc

The biogeographical history of hyperdiverse and flightless Trigonopterus weevils is revealed and different approaches to ancestral area reconstruction suggest a complex east to west range expansion.


The results provide a complementary perspective, indicating that the rate of phenotypic diversification declines with decreasing opportunity in an adaptive radiation.

Mammals of New Guinea

A definitive published work on the mammals of New Guinea, the world's second largest island. The book presents information on all aspects of the island's mammals.

Evolutionary Processes of Diversification in a Model Island Archipelago

An ongoing renaissance of species discovery is characterized and how a 25-year Pleistocene island connectivity paradigm continues to provide some explanatory power, but has been augmented by increased understanding of the archipelago's geological history and ecological gradients is described.
