The Autumn Migration August 1-November 30, 1982 CONTINENTAL SURVEY The Autumn Migration August 1--November 30, 1982 NORTHEASTERN MARITIME REGION /Richard A. Forster It is extraordinarily difficult to capsulizea seasonas diverse as fall in terms of numbers of speciesand bulk of migrants. This report will surely overlook some records and observers' sightingsin the more than 300 pagesof reports received. Any oversightis clearly mine. In generalweather during the period was not conduciveto migra- tion. Many of the cold fronts that moved through the area took an unusual track producing northeast rather than northwest winds. A moderatenor'easter in October producedsome excitement, at least in coastalMassachusetts, but suchstorms have becomeless depend- able than in the past. High temperaturesand strong southwestwinds in October, and particularly in November, favored reversemigration and provided some extremely late records. The generalconsensus was that it was almostuniversally a poorfall ATLANTIC migration.Field observersare not out constantlyand if observersare not out when major flights occur then migration is termed a bust. A OCEAN truer sense of overall migration can be judged by banding stations whose efforts are relatively constantfrom year to year but subjectto Vineyard the vagaries of weather. At Mahomet Bird Observatory (hereafter, M.B.O.), Lloyd-Evans termed the migration "average" with some speciesdown .•nd othersmaking a recoveryfrom recentlosses. One final comment. The overwhelmingbulk of reports emanates from offshore islands and barrier beaches where knowledgeable SoAo observersgo to see rare speciesand concentratedmigrants. Obvi- ously unfavorableweather will producewidely varying resultsfrom In the past, few pelagic trips have been attempted in late summer to the warm waters s. and w. of Massachusetts but 2 year to year. were made this season. A 2'/2 day trip met with spectacular LOONS, GREBES -- The first migrant Red-throated Loons were successat HydrographerCanyon about 75 mi s.e. of Nantuc- ket. Fortunate observers were treated to views of White-faced noted in Newfoundland in mid-September but the only numbers of Storm-Petrel, Audubon's Shearwater, South Polar Skua and any consequencewere noted at Pt.

  • Mollusks Background the Florida Keys Marine Ecosystem Supports a Diverse Fauna of Mollusks Belonging to Several Orders
    2010 Quick Look Report: Miller et al. VII. Abundance and Size of Selected Mollusks Background The Florida Keys marine ecosystem supports a diverse fauna of mollusks belonging to several orders. Opisthobranch mollusks, for example, are represented by at least 30 species of sea slugs (Sacoglossa) and 23 species of nudibranchs (Nudibranchia) (Clark and DeFreese 1987; Levy et al. 1996), including at least three endemic species (Clark 1994). Data on the status and trends of mollusk populations and habitat utilization patterns in the Florida Keys, with the exception of queen conch (Strombus gigas), are generally limited (Marcus 1960; Jensen and Clark 1983; Clark and DeFreese 1987), as most previous studies have been qualitative in nature (Clark 1994; Trowbridge 2002). Clark (1994) noted a declining population trend for the lettuce sea slug, Elysia (Tridachia) crispata Mörch (see cladistic analyses in Gosliner 1995; Jensen 1996) in southern Florida, based upon qualitative comparisons of occurrence and population densities between 1969-80 and 1987-93. About 50% of the nearshore populations assessed by Clark (1994) nearly 17 years ago were declining due to habitat destruction, siltation, eutrophication, and over- collection, particularly evident in nearshore habitats. Since 2001, we have conducted intermittent surveys of various gastropod mollusk species in conjunction with assessments of other benthic variables. For example, we encountered unusually high densities of lettuce sea slugs among 63 shallow fore reef sites during June-September 2001. While sacoglossans are not particularly rare in many shallow-water marine habitats where densities correlate with algal biomass (Clarke and DeFreese 1987), our observations offshore were considered unusual because fleshy algal cover tends to be relatively low (Chiappone et al.

Abstract A new genus of the subfamily Pontoniinae, Ancylomenes gen. nov. is established for the ‘Periclimenes aesopius species group’ of the genus Periclimenes Costa. The new genus is distinguished from other genera of Pontoniinae on account of the strongly produced inferior orbital margin with reflected inner flange, and the basicerite of the antenna armed with an angular dorsal process. Fourteen species have been previously recognized as belonging to the ‘P. aesopius species group’. One Eastern Pacific species (P. lucasi Chace), and two Atlantic species (P. anthophilus Holthuis & Eibl- Eibesfeldt, and P. pedersoni Chace) are now also placed in Ancylomenes gen. nov.

    Limnology and Oceanography In Press Temporal and Spatial Variation in the δ15N and δ13C of coral tissue and zooxanthellae in Montastraea faveolata collected from the Florida reef tract Peter K. Swart, Amel Saied and Kathryn Lamb Marine Geology and Geophysics Rosenstiel School of Marine and Atmospheric Sciences University of Miami Miami Fl 33149 [email protected] Abstract Small pieces of coral skeletons with their associated tissues were collected at monthly intervals, between January 1995 and December 1996, from specimens of Montastraea faveolata at five locations on the Florida Reef tract. The locations (Triangles, Pickles Reef, Crocker Reef, Hen and Chickens, and The Rocks) represent both near shore and off shore environments. During each sampling trip between one to four pieces of coral skeleton and associated tissues were collected from the sides of different colonies living in water depths between 3 to 4 m. At one site (Pickles) samples were also collected from 8 m water depth. The tissue and zooxanthellae were removed from the skeletons, separated, and subsequently analyzed for δ15N and δ13C. The mean δ15N value in the coral tissue of all samples was +6.6 (+/- 0.6 ‰) while the δ13C was -13.3 (+/- 0.5 ‰) (n=197). The δ15N and δ13C of the zooxanthellae were +4.7 (+/-1.1‰) and -12.2 (+/- 1.0 ‰) respectively (n=147). The differences in the δ15N and δ13C between the zooxanthellae and the coral tissue were statistically significant. No statistically significant differences were observed between near shore and offshore stations in either δ15N or δ13C. The absence of a difference between the inshore and offshore stations casts doubt on both whether the δ15N of the coral tissues is related to anthropogenic influences and whether the δ15N value itself can be used as an indicator of sewage contamination in corals.
