biogeographical barriers: perspectives from two widespread Indo-Pacific snappers (Lutjanus kasmira and Lutjanus fulvus)
TL;DR: In this article, the authors used mitochondrial-sequence comparisons to evaluate the efficacy of biogeographical barriers on populations of the snappers Lutjanus kasmira and Lutsanus fulvus across their natural ranges.
Journal ArticleDOI
Evidence of local adaptation in a waterfall-climbing Hawaiian goby fish derived from coupled biophysical modeling of larval dispersal and post-settlement selection
Kristine N. Moody,Kristine N. Moody,Kristine N. Moody,Johanna L. K. Wren,Johanna L. K. Wren,Donald R. Kobayashi,Michael J. Blum,Michael J. Blum,Margaret B. Ptacek,Richard W. Blob,Robert J. Toonen,Heiko L. Schoenfuss,Michael J. Childress +12 more
TL;DR: It is found that immigration can act in concert with selection to favor local adaptation and divergence in species with marine larval dispersal, and that ontogenetic shifts in habitat can give rise to adaptive morphological divergence when the strength of predation-driven post-settlement selection crosses a critical threshold.
Journal ArticleDOI
An Evaluation of Cryptic Lineages of Idotea Balthica (Isopoda: Idoteidae): Morphology and Microsatellites
TL;DR: Development of microsatellite loci for Idotea and use these newly developed markers to evaluate population structure among the mitochondrial clades, indicating that nuclear loci may show similar differentiation as mtDNA among regions.
Journal ArticleDOI
Discordant population expansions in four species of coral‐associated Pacific hermit crabs (Anomura: Diogenidae) linked to habitat availability resulting from sea‐level change
TL;DR: To explore the spatial and temporal genetic structure of four tropical hermit crabs with varying habitat use in order to test for impacts of sea‐level change and demography in shaping contemporary population structure and to understand how this structure relates to the process of speciation in the genus Calcinus.
Journal ArticleDOI
The implementation of rare events logistic regression to predict the distribution of mesophotic hard corals across the main Hawaiian Islands
Lindsay M. Veazey,Erik C. Franklin,Christopher Kelley,John J. B. Rooney,L. Neil Frazer,Robert J. Toonen +5 more
TL;DR: These maps are the first of their kind to use extant presence and absence data to examine the habitat preferences of these two dominant mesophotic coral genera across Hawai’i.
