Seaside Sparrows "Ammospiza maritima" are tidal salt marsh endemic passerines found along the Atlantic and Gulf Coasts. At present there has not been a modern genetic assessment of the Atlantic Coast clade, which consists of two extant subspecies: the Northern Seaside Sparrow, "A. m. maritima" (Wilson 1811), and MacGillivray's Seaside Sparrow, "A. m. macgillivraii" (Audubon 1870). The currently described ranges of these subspecies are from Massachusetts to North Carolina (Northern) and North Carolina to Florida (MacGillivray's). We analyzed genetic (microsatellite and mitochondria) data from 400 Seaside Sparrows from Connecticut to Florida (2000 - 2017). Sampling efforts were focused (1) near the currently defined geographic boundary between the subspecies (Dare County, NC), and (2) the type locality for MacGillivray's Seaside Sparrow (Charleston, SC). Bayesian cluster analysis (program STRUCTURE) indicates three genetically distinct population segments, which were recovered regardless of how the data were subsampled. The population in Charleston, SC was the most strongly differentiated population, and this population also harbored a unique mitochondrial (mtDNA) "signature," likely reflecting long-standing isolation. These results indicate discordance with the currently described ranges of the subspecies of Seaside Sparrow, and provide grounds for the consideration of separate management plans for the three populations.

The distinctiveness, genetic relatedness and geographic distributions of Seaside Sparrow subspecies along Florida's coastline are poorly understood. Along the gulf coast are two state-listed subspecies that some suggest represent a single genetic unit. In this work, genome-wide single nucleotide polymorphisms (SNPs) generated via double digest restriction site associated DNA sequencing (ddRADseq), were used to assess whether genetic clusters corresponded geographically with the defined ranges of current subspecific taxa. To further examine relationships between taxa, and to potentially develop tools for identification in the field, geographic differences in phenotypic characteristics were utilized to evaluate whether morphologic characteristics, or key parameters of primary song corresponded with defined subspecific ranges or genetic groups. Results from this study bring added support for the lack of distinctiveness of Ammospiza maritima juncicola from Ammospiza maritima peninsula and better define the geographic boundaries between the reproductive units along Florida's coastline. This data will help to inform conservation efforts for this species.

Current Ornithology publishes authoritative, up-to-date, scholarly reviews of topics selected from the full range of current research in avian biology. Topics cover the spectrum from the molecular level of organization to population biology and community ecology. The series seeks especially to review (1) fields in which an abundant recent literature will benefit from synthesis and organization, or (2) newly emerging fields that are gaining recognition as the result of recent discoveries or shifts in perspective, or (3) fields in which students of vertebrates may benefit from comparisons of birds with other classes. All chapters are invited, and authors are chosen for their leadership in the subjects under review.

This edited volume is a collection of population and metapopulation models for a wide variety of species, including plants, invertebrates, fishes, amphibians, reptiles, birds, and mammals. Each chapter of the book describes the application of RAMAS GIS 4.0 to one species, with the aim of demonstrating how various life history characteristics of the species are incorporated into the model, and how the results of the model has been or can be used in conservation and management of the species. The book comes with a CD that includes a demo version of the program, and the data files for each species.
