Status survey of two Florida seaside sparrows and taxonomic review of the Seaside Sparrow assemblage

The original primary intent of this project was to determine the population status of two relatively obscure subspecies of Seaside Sparrows in Florida, the Smyrna Seaside Sparrow Cammodramus maritimus Eelonota) and the Wakulla Seaside Sparrow (Ammodramus maritimus juncicola) distinctiveness of these little known birds. As explained in the following section, a third and major objective appended to the project was to perform a taxonomic review of the entire Seaside Sparrow complex of nine subspecies.

Davidson Seamount Taxonomic Guide

Davidson Seamount is one of the largest seamounts in U.S. waters and the first to be characterized as a “seamount.” In 2002 and 2006, the Monterey Bay National Marine Sanctuary (MBNMS) led two multi-institutional expeditions to characterize the geology and natural history of Davidson Seamount. Results from these expeditions to Davidson Seamount are adding to the scientific knowledge of seamounts, including the discovery of new species. In November 2008, the MBNMS boundary was expanded to include the Davidson Seamount. In addition, a management plan for Davidson Seamount was created to develop resource protection, education, and research strategies for the area. The purpose of this taxonomic guide is to create an inventory of benthic and mid-water organisms observed at the Davidson Seamount to provide a baseline taxonomic characterization. At least 237 taxa were observed and are presented in this guide; including 15 new or undescribed species (8 sponges, 3 corals, 1 ctenophore, 1 nudibranch, 1 polychaete, 1 tunicate) recently or currently being described by taxonomic experts. This is the first taxonomic guide to Davidson Seamount, and is intended to be revised in the future as we learn more about the seamount and the organisms that live there. (PDF has 145 pages.)

A taxonomic guide to the mysids of the South Atlantic Bight.

Following the examination of extensive collections from the National Museum of Natural History (NMNH), the Southeastern Regional Taxonomic Center (SERTC), and other regional institutions, 18 species of the family Mysidae are recognized and described from the South Atlantic Bight (Cape Lookout, North Carolina to Cape Canaveral, Florida). This report includes synonymies of previous records, as well as new species distribution records. Previous regional accounts of Metamysidopsis munda and Metamysidopsis mexicana are attributed to Metamysidopsis swifti. New regional records are established for Amathimysis brattegardi, Heteromysis beetoni, and Siriella thompsonii. Two other species tentatively identified as Amathimysis sp. (nr. serrata) and Mysidopsis sp. (cf. mortenseni) may represent new taxa. Neobathymysis renoculata is included and discussed as a potential regional species. An illustrated key to the species currently known from the South Atlantic Bight is presented. Relevant taxonomic, distributional, and ecological information is also included for each species.

Additions to a revision of the shark genus Carcharhinus: Synonymy of Aprionodon and Hypoprion, and description of a new species of Carcharhinus (Carcharhinidae)

Features of the valid nominal species of Aprionodon Gill (isodon Valenciennes) and Hypoprion Muller and Henle (hemiodon Valenciennes, macloti Muller and Henle, and signatus Poey), plus those of a previously unrecognized species here described as Carcharhinus leiodon n.sp., are examined and compared with those of Carcharhinus Blainville. Features studied include morphometrics, vertebral numbers and other vertebral characteristics, tooth numbers, color pattern, and some other aspects of external morphology. It is concluded that on these features C. leiodon n.sp. is entirely encompassed within the parameters of Carcharhinus, and that, although A. isodon, H. hemiodon, H. macloti, and H. signatus each extend the range of diversity of Carcharhinus in one or more features, A. isodon is not uniquely different from Carcharhinus, and there is no common pattern of difference between the three species of Hypoprion and Carcharhinus. Accordingly, and because the nature of the teeth of Aprionodon and Hypoprion has been found insufficient to warrant generic distinction from Carcharhinus, the genera Aprionodon and Hypoprion are synonymised with Carcharhinus. A diagnosis and description are given for each of the above species. The descriptions include measurements, counts, and line illustrations that show the whole shark in lateral view, underside of head, nostril, and teeth. The geographic distribution is summarized, as are also the meager biological data available on number of embryos, size at birth, size at sexual maturity, and maximum size.

Taxonomic study of brown algae commonly growing on the coast of Karachi, Pakistan

Fourteen commonly occurring species of marine benthic algae, i.e., Colpomenia sinuosa (Mertens ex Roth) Derbes et Solier, Dictyopteris australis (Sonder) Askenasy, Dictyota dichotoma (Hudson) Lamouroux D. dumosa Børgesen, D. hauckiana Nizamuddin, D. indica Sonder, D. maxima Zanardini, Hincksia mitchelliae (Harvey) Silva, Jolyna laminarioides Guimardes in Guimarâes et al., Padina tetrastromatica Hauck, Sargassum tenerrinum J. Agardh, Spatoglossum variabille Figari et De Notaris, Stoechospermum marginatum (C. Agardh) Kültzing and Stokeyia indica Thivy et Doshi, belonging to all three classes of Phaeophyta, were collected from coastal areas near Karachi, Pakistan and their taxonomy determined. Although all are taxonomically known species, Dictyota dichotoma, D. dumosa, D. hauckiana, D. indica, D. maxima, Jolyna laminarioides, Padina tetrastromatica, Sargassum tenerritnum and Stokeyia indica are described for the first time from the coast of Pakistan.

Taxonomic notes on a collection of flying fishes from Ceylon waters

The present study reports another seven species of flying fishes and brings the total for Ceylon to fifteen. Eleven of these fifteen species are represented in the author's collection. A key based on Breader (1938) and Parin (1960) and descriptive notes for these eleven species are given in this paper.
