Seahorse (Hippocampus erectus) collected at Pier 40 in the lower Hudson River, New York City, current home of the The River Project (www.riverprojectnyc.org). I worked there for five years, and they do terrific work educating residents of NYC about local marine and estuarine species. They also have a really cool wet-lab and "Estuarium." J.T. Boehm seahorse

Three forms of genomic analyses based on 5,777 short genome-wide loci (Boehm et al. 2015 : Population genomics reveals coastal western mid-Atlantic seahorses (Hippocampus erectus) to be residents rather than vagrants. PLoS ONE 10(1): e0116219). These results support the hypothesis that temperate populations of H. erectus make up a persistent ancestral gene pool : (a) Treemix population phylogeny with branch lengths scaled to the amount of genetic drift between regions and inferred proportion of genetic admixture (m=2) between southern and northern regions represented by arrows. Dotted lines do not represent branch lengths. (b) Principle component analysis. Black circles = Chesapeake Bay-New York, dark grey circles = Florida Atlantic coast, and light grey circles = Gulf of Mexico-Florida Keys. Pie diagrams (a) represent ancestry coefficient proportions derived from the sNMF ancestry plot (c). Each line of the sNMF plot represents one individual._
