the contribution of habitat loss to changes in body size, allometry, and bilateral asymmetry in two eleutherodactylus frogs from puerto rico.	amphibian populations have been declining worldwide and the exact mechanisms underlying these changes are not well understood. we examined environmentally induced phenotypic changes that may reflect ongoing stresses on individuals and therefore their ability to persist in increasingly changing landscapes. specifically, we evaluated the contribution of habitat loss on the size, allometry, and levels of fluctuating asymmetry of eleutherodactylus antillensis and e. coqui, 2 common species that are ...	2008	18477027
sea level, topography and island diversity: phylogeography of the puerto rican red-eyed coquí, eleutherodactylus antillensis.	quaternary climatic oscillations caused changes in sea level that altered the size, number and degree of isolation of islands, particularly in land-bridge archipelagoes. elucidating the demographic effects of these oscillations increases our understanding of the role of climate change in shaping evolutionary processes in archipelagoes. the puerto rican bank (prb) (puerto rico and the eastern islands, which comprise vieques, culebra, the virgin islands and associated islets) in the eastern caribb ...	2012	23163292
origins and genetic diversity of introduced populations of the puerto rican red-eyed coquí, eleutherodactylus antillensis, in saint croix (u.s. virgin islands) and panamá.	the red-eyed coquí, eleutherodactylus antillensis, is a terrestrial frog endemic to the puerto rican bank (puerto rico and numerous islands and cays off its eastern coast), in the eastern caribbean sea. the species was likely introduced in saint croix, an island c. 100 km southeast of puerto rico, in the late 1930s, and in panamá city, panamá, in the late 1950s or early 1960s, but the source(s) of these introductions are unknown. we analyzed sequence data from one mtdna locus and four nudna intr ...	2017	28649148
