Additions, combinations, and synonyms for the Bolivian moss flora

Fifty-five mosses are newly recorded for Bolivia. Additional collection data are given for twelve mosses considered little known or rare in the country. Six new synonyms are recognized, five from Bolivia, one from Brazil: Hookeria scabripes Müll. Hal. [Callicostella scabripes (Müll. Hal.) Broth.] = Callicostella pallida (Hornsch.) Ångstr.; Leucobryum fragile Herzog = Leucobryum subobtusifolium (Broth.) B.H. Allen; Macromitrium pinnulatum Herzog = Macromitrium microstomum (Hook. & Grev.) Schwägr.; Schlotheimia vesiculata Herzog [Macromitrium vesiculatum (Herzog) Herzog] = Macromitrium stellulatum (Hornsch.) Brid.; Cyclodictyon breve Herzog = Cyclodictyon albicans (Hedw.) Kuntze; and from Brazil: Callicostella paludicola Broth. = Callicostella merkelii (Hornsch.) A. Jaeger. Three new combinations are proposed: Entosthodon subaloma (Herzog) S.P. Churchill (Goniobryum subaloma Herzog), Syntrichia xerophila (Herzog) S.P. Churchill (Tortula xerophila Herzog), Thamniopsis lepidopiloides (Herzog) S.P. Churchill (Hookeriopsis lepidopiloides Herzog)

Bryologia novo granatensis : estudios de los musgos de colombia IV ; catalogo nuevo de los musgos de colombia

A revised moss checklist for Colombia recognizes 877 species distributed among 242 genera and 65 families. Departmental distribution is provided for all species. This paper is based on the previous checklist by Florschütz-de Waard & Florschütz (1979), publications since that time, on the extensive holdings of the New York Botanical Garden, the Institute of Systematic Botany, Utrecht, and other herbaria, and on recent field work. Included in this list are a number of the collections made by Aguirre C., Cleef, Griffin, Killip, Schultes, Steere, van der Hammen and van Reenen, among others, which have not previously been incorporated into the Colombian moss literature. Comparison of the number of species reported for each of the departments based on the 1979 and the present checklist both suggest that over half of the departments are poorly known. Forty new additions to Colombia are provided in this catalogue: Amblystegium serpens, Anoectangium aestivum, Astomiopsis amblycalyx, Breutelia brevifolia, Brymela parkeriana, Bryohaplocladium praelongum, Bryum coloratum, B. perlimbatum, Chorisodontium setaceum, Dicranum peruvianum, Drepanocladus uncinatus, Encalypta asperifolia, Entodon hampeanus, Epipterygium immarginatum, Fissidens allionii, F. diplodus, F. intermedius, Groutiella obtusa, Gymnostomum recurvirostrum, Hymenodon reggaeus, Leiomela ecuadorensis, Lepidopilum affine, L. cuspidans, L. cubense, Leptodontium stellaticuspis, Leskea plumaria, Leskeadelphus bolivianus, Neckera urnigera, Potamium deceptivum, P. pacimonense, Pseudotaxiphyllum distichaceum, Rhegmatodon polycarpa, Schistidium apocarpum, S. rivulare ssp. latifolium, Scorpidium scorpioides, Syrrhopodon steyermarkii, Tortula caroliniana, Zygodon ehrenbergii, Z. fragilis, Z. stenocarpus. Approximately 560 new departmental records are included. Several new combinations are made: Calyptrochaeta deflexa (C. Muell.) comb. nov., C. nutans (Hampe) comb. nov., Pleuridium subenervis (Hampe) comb. nov., Rhodobryum perspinidens (Broth.) comb. nov., R. roseodens (C. Muell.) comb. nov., Schizymenium brevicaulis (Hornsch.) comb. nov., S. dolichothecum (Herz.) comb. nov., S. pectinatum (C. Muell.) comb. nov., S. subobliquum (Hampe) comb. nov., Sematophyllum sticticola (C. Muell.) comb. nov. and, S. turgidulum (Herz.) comb. nov. Several further species are reduced to synonymy: Aulacomnium venezuelanum Mitt. (=A. palustre), Grimmia bogotense (Hampe) Jaeg. (=G. longirostris), Mielichhoferia elegans Herz. (=Schizymenium bogotense), Pohlia integridens (C. Muell.) Broth. (=P. elongata), and P. paucifolia (Jaeg.) Broth. (=P. elongata)

Coral reef drag coefficients—surface gravity wave enhancement

Author Posting. © American Meteorological Society, 2018. This article is posted here by permission of American Meteorological Society for personal use, not for redistribution. The definitive version was published in Journal of Physical Oceanography 48 (2018): 1555-1566, doi:10.1175/JPO-D-17-0231.1.A primary challenge in modeling flow over shallow coral reefs is accurately characterizing the bottom drag. Previous studies over continental shelves and sandy beaches suggest surface gravity waves should enhance the drag on the circulation over coral reefs. The influence of surface gravity waves on drag over four platform reefs in the Red Sea is examined using observations from 6-month deployments of current and pressure sensors burst sampling at 1Hz for 4–5min. Depth-average current fluctuations U0 within each burst are dominated by wave orbital velocities uw that account for 80%–90%of the burst variance and have a magnitude of order 10 cm s21, similar to the lower-frequency depth-average current Uavg. Previous studies have shown that the cross-reef bottom stress balances the pressure gradient over these reefs. A bottom stress estimate that neglects the waves (rCdaUavgjUavgj, where r is water density and Cda is a drag coefficient) balances the observed pressure gradient when uw is smaller than Uavg but underestimates the pressure gradient when uw is larger than Uavg (by a factor of 3–5 when uw 5 2Uavg), indicating the neglected waves enhance the bottom stress. In contrast, a bottom stress estimate that includes the waves [rCda(Uavg 1 U0)jUavg 1 U0j)] balances the observed pressure gradient independent of the relative size of uw and Uavg, indicating that this estimate accounts for the wave enhancement of the bottom stress. A parameterization proposed by Wright and Thompson provides a reasonable estimate of the total bottom stress (including the waves) given the burst-averaged current and the wave orbital velocity.The Red Sea field program was supported by Awards USA 00002 and KSA 00011 made by KAUST.

Diets of Young King and Spanish Mackerel Off the Southeast United States

The diet of larval and post-larval (n = 95 and 307), and juvenile (n = 489 and 508) king (Scomberomorus cavalia) and Spanish mackerel (S. maculatus) from the Gulf of Mexico and southeastern Atlantic coastal waters of the U.S. consisted principally of fishes. Carangids, clupeids, and engraulids occurred in 23, 7 and 9% of larval and post-larval king mackerel stomachs and in 20, 40 and 7% of larval and post-larval Spanish mackerel stomachs, respectively. Sciaenids were also common in king mackerel, occurring in 21% of the stomachs. Prey fishes included the genera Cynoscion, Caranx, and Anchoa, and the species Opisthonema oglinum. Invertebrates, principally small crustaceans and nudibranch larvae, occurred infrequently in the diets of both species, but more so in Spanish mackerel than king mackerel. The dominant prey items for juvenile mackerels from the Atlantic were engraulids, clupeids, balistids, and squids, collectively accounting for 73.3% by volume of the diet of king mackerel and 88.8% of Spanish mackerel. More invertebrates occurred in the diet of juvenile Spanish mackerel than king mackerel, but they accounted for a smaller volume, i.e., 2.1% as compared to 5.4% for the Atlantic fish. Chi-square tests indicated significant differences between the diets of juvenile mackerel from the Gulf of Mexico and the Atlantic coast
