Islands and Non-islands in Native and Heritage Korean

To a large extent, island phenomena are cross-linguistically invariable, but English and Korean present some striking differences in this domain. English has wh-movement and Korean does not, and while both languages show sensitivity to wh-islands, only English has island effects for adjunct clauses. Given this complex set of differences, one might expect Korean/English bilinguals, and especiall...

Genomic islands of speciation or genomic islands and speciation?

Populations of the malaria mosquito, Anopheles gambiae, are comprised of at least two reproductively isolated, sympatric populations. In this issue, White et al. (2010) use extensive sampling, high-density tiling microarrays, and an updated reference genome to clarify and expand our knowledge of genomic differentiation between these populations. It is now clear that DNA near the centromeres of ...

Lattices and Islands

The talk will give an overview of the following topic: A rectangular m × n board consisting of square cells is given, with a positive integer (height) associated to each cell. A rectangular island is a rectangle in the board such that the height of its cells are greater than the heights of all neighboring cells. The notion of an island comes from information theory. The characterization of the ...

Islands, equilibria, and speciation.

Ricklefs and Bermingham (1) demonstrated that divergence times of Lesser Antillean avifauna from sister taxa do not follow the exponential distribution predicted with constant colonization and extinction rates (2). Their explanation for this observation was a lack of equilibrium due to historical changes in colonization or extinction rates. However, they mistakenly estimated species numbers fro...
