We compared population density estimates from a visual survey (VS) point quadrat method widely used in Hawaii with estimates from “in hand” individual and batch mark–recapture (BMR) methods. Visual survey sampling and individual mark–recapture (IMR) sampling were conducted in three watersheds that represent gradients of land use and prevalence of nonnative poeciliid fishes on the Island of Hawaii. Focusing on adult O‘opu Nākea Awaous stamineus, VSs were conducted prior to IMR events to allow direct comparisons of results independent of location and time. Density estimates of O‘opu Nākea from VS and IMR samplings were strongly correlated, although VS estimates were generally higher and underrepresented exceptionally large fish. Batch mark–recapture estimates of O‘opu Nākea densities were conducted for comparison with VSs at 13 sites across the archipelago. Estimates of VSs were not significantly different from BMR estimates. Estimates of VSs also exhibited less variance than did BMR estimates across sites. General linear models showed that the relationship between VS and IMR estimates varied significantly among watersheds but not seasons and that land use was associated with a greater mismatch between VS and BMR estimates of population density. These findings indicate that visual surveys using a point quadrat method are an efficient and accurate approach for estimating the abundance of small benthic fishes, such as O‘opu Nākea, in wadeable streams and that obtaining absolute densities or size distributions from VS methods would benefit from a calibration with IMR not BMR estimates.Received July 15, 2015; accepted February 23, 2016 Published online June 29, 2016}, number={4}, journal={TRANSACTIONS OF THE AMERICAN FISHERIES SOCIETY}, author={Hain, Ernie F. and Lamphere, Bradley A. and Blum, Michael J. and McIntyre, Peter B. and Nelson, Stacy A.

Some secondary freshwater fish, however, exhibit pronounced genetic differentiation and geographic structure on islands, whereas others do not. It is unclear what conditions give rise to contrasting patterns of differentiation because few comparative reconstructions of population history have been carried out for insular freshwater fishes. In this study, we examined the phylogeography of Hart’s killifish (Rivulus hartii) across Trinidad, with reference to neighboring islands and northern South America, to test hypotheses of colonization and differentiation derived from comparable work on co‐occurring guppies (Poecilia reticulata). Geographic patterns of mitochondrial DNA haplotype variation and microsatellite genotype variation provide evidence of genetic differentiation of R. hartii among islands and across Trinidad. Our findings are largely consistent with patterns of geographically structured ancestry and admixture found in Trinidadian guppies, which suggests that both species share a history of colonization and differentiation and that post‐colonization diversification may be more common among members of insular freshwater fish assemblages than has been previously thought.}, number={3}, journal={MOLECULAR ECOLOGY}, author={Walter, Ryan P. and Blum, Michael J. and Snider, Sunny B. and Paterson, Ian G. and Bentzen, Paul and Lamphere, Brad A. and Gilliam, James F.}, year={2011}, month={Feb}, pages={601–618} } @article{palkovacs_marshall_lamphere_lynch_weese_fraser_reznick_pringle_kinnison_2009, title={Experimental evaluation of evolution and coevolution as agents of ecosystem change in Trinidadian streams}, volume={364}, number={1523}, journal={Philosophical Transactions of the Royal Society of London.
