The seaweed flora of Admiralty Bay, King George Island, Antarctic

Admiralty Bay is located on the western side of King George Island. Although several research teams of different nationalities have carried out surveys in the region for decades, there are only two publications dealing with the seaweed flora of the bay. Here, we report on a taxonomic survey of the seaweeds we collected during the 25th Brazilian Antarctic Expedition (December 2006/November 2007). We discovered 42 species (21 Rhodophyta, 14 Phaeophyceae, and 7 Chlorophyta), corresponding to an increase of about 31% in the seaweed biodiversity hitherto known for the region. Considering that the Antarctic Peninsula, adjacent to King George Island seems to be one of the most rapidly warming spots on the planet, this kind of survey may provide a valuable tool for detecting eventual changes in seaweed biodiversity.

Cladistic analysis of the suborder Conulariina Miller and Gurley, 1896 (Cnidaria, Scyphozoa; Vendian-Triassic)

Results of a cladistic analysis of the suborder Conulariina Miller and Gurley, 1896, a major extinct (Vendian-Triassic) group of scyphozoan cnidarians, are presented. The analysis sought to test whether the three conulariid subfamilies (Conulariinae Walcott, 1886, Paraconulariinae Sinclair, 1952 and Ctenoconulariinae Sinclair, 1952) recognized in the Treatise on Invertebrate Paleontology ( TIP) are monophyletic. A total of 17 morphological characters were scored for 16 ingroup taxa, namely the genera Archaeoconularia, Baccaconularia, Climacoconus, Conularia, Conulariella, Conularina, Ctenoconularia, Eoconularia, Glyptoconularia, Metaconularia, Notoconularia, Paraconularia, Pseudoconularia, Reticulaconularia, Teresconularia and Vendoconularia. The extant medusozoan taxa Cubozoa, Stauromedusae, Coronatae and Semaeostomeae served as outgroups. Unweighted analysisof the data matrix yielded 1057 trees, and successive weighting analysis resulted in one of the 1057 original trees. The ingroup is monophyletic with two autapomorphies: (1) the quadrate geometry of the oral region; and (2) the presence of a mineralized (phosphatic) periderm. Within the ingroup, the clade (Vendoconularia, Teresconularia, Conularina, Eoconularia) is supported by the sinusoidal longitudinal geometry of the transverse ridges, and the much larger clade (Baccaconularia, Glyptoconularia, Metaconularia, Pseudoconularia, Conularia, Ctenoconularia, Archaeoconularia, Notoconularia, Climacoconus, Paraconularia, Reticulaconularia) is supported by the presence of external tubercles, which, however, were lost in the clade (Notoconularia, Climacoconus, Paraconularia, Reticulaconularia). As proposed by Van Iten et al. (2000), the clade (Notoconularia, Climacoconus, Paraconularia, Reticulaconularia) is supported by the termination and alternation of the transverse ribs in the corner sulcus. The previously recognized subfamilies Conulariinae, Paraconulariinae and Ctenoconulariinae were not recovered from this analysis. The diagnostic features of Conulariinae (continuation of the transverse ornament across the corner sulcus and lack of carinae) and Ctenoconulariinae ( presence of carinae) are symplesiomorphic or homoplastic, and Paraconulariinae is polyphyletic. The families Conulariellidae Kiderlen, 1937 and Conulariopsidae Sugiyama, 1942, also recognized in the TIP, are monogeneric, and since they provide no additional phylogenetic information, should be abandoned.

Patterns of water and heat flux across a biome gradient from tropical forest to savanna in Brazil

We investigated the seasonal patterns of water vapor and sensible heat flux along a tropical biome gradient from forest to savanna. We analyzed data from a network of flux towers in Brazil that were operated within the Large-Scale Biosphere-Atmosphere Experiment in Amazonia (LBA). These tower sites included tropical humid and semideciduous forest, transitional forest, floodplain (with physiognomies of cerrado), and cerrado sensu stricto. The mean annual sensible heat flux at all sites ranged from 20 to 38 Wm(-2), and was generally reduced in the wet season and increased in the late dry season, coincident with seasonal variations of net radiation and soil moisture. The sites were easily divisible into two functional groups based on the seasonality of evaporation: tropical forest and savanna. At sites with an annual precipitation above 1900 mm and a dry season length less than 4 months (Manaus, Santarem and Rondonia), evaporation rates increased in the dry season, coincident with increased radiation. Evaporation rates were as high as 4.0 mm d(-1) in these evergreen or semidecidous forests. In contrast, ecosystems with precipitation less than 1700 mm and a longer dry season (Mato Grosso, Tocantins and Sao Paulo) showed clear evidence of reduced evaporation in the dry season. Evaporation rates were as low as 2.5 mm d(-1) in the transitional forests and 1 mm d(-1) in the cerrado. The controls on evapotranspiration seasonality changed along the biome gradient, with evaporative demand (especially net radiation) playing a more important role in the wetter forests, and soil moisture playing a more important role in the drier savannah sites.

En rörelse formas : bildandet av Dalarnas mejeriförening 1931-1933

Syftet med uppsatsen är att kartlägga bildandet av Dalarnas mejeriförening med hjälp avfrågeställningar angående hur, varför och av vilka personer föreningen skapades samt hurorganisationen Dalarnas mejeriförening kan tolkas med teorier om sociala rörelser och sociala nätverk. Undersökningen baserar sig på källmaterial från Dalarnas mejeriförening ochKopparbergs läns hushållningssällskap. Resultatet av undersökningen är att Dalarnasmejeriförening kan anses vara en social rörelse som bildades för att kontrollera mejerihanteringen i Dalarna. Dalarnas mejeriförening implementerade en omorganisering ilinje med den kooperationsteoretiska rörelseteorin. Rörelsens organisation var baserad på enregelorienterad tolkning av kooperationsprinciperna och rörelseideologin på envärdeorienterad tolkning av desamma. Rörelsens mobiliseringsstruktur var god på grund av en fördelaktig politisk möjlighetsstruktur och framgångsrika nätverksrelationer både inom rörelsen men också mellan rörelsen och andra jordbruksorganisationer.

George Sand : une femme moderne ?

A travers des œuvres de George Sand (1804-1876), le mémoire étudie la littérature champêtre, l'exotisme et l’écriture féminine. Dans un deuxième temps il montre les relations avec des personnes célèbres qui ont influencé l’auteur et les correspondances entretenues entre George Sand et elles. Enfin le mémoire se termine par une étude de la femme moderne qu'était George Sand.

Levine Family Reunion Members, interviewed by Wendy Miller in September 2009: Transcript

The Levine family held an extensive reunion during the Summer of 2009 during which 29 DVDs of raw material were recorded for use in the creation of a Levine family mini-documentary. Many of these DVDs contain oral history interviews conducted by Wendy Miller, one of the organizers of the reunion. Although these interviews were not designed for historical research, they contain valuable historical information. Some of the family members interviewed include: Ben Arnon (4/5), Marjorie, Stephen, and Michael Kaplan (8), Glenyce Miller Kaplan (starts in 15, continues in 9; separate interview in 13), Burt, Phyllis, and Louis Shiro (9) [Burt Shiro also in 26/27], Myrt and Gordon Wolman (9), Ted and Billy Alfond (10), Barbara and Joan Alfond (10), Susan and Peter Alfond (10), Alice Emory [caregiver for Bibby] (11), Eric Bloom and Stu Cushner (11), Saralee Kaplan Bloom (11), Sarah Miller Arnon (12), Kayla and Jenna Cushner (12), Josh Soros and Eliana Miller-Kaplan (12), Sarah, Wendy, and Julie Miller (starts in 12, continues in 14), Bill Shutzer (13), Maschia and Glicka Kaplan, Sharon Kushner, Dan Hood (13), Gene, Alex, Kate Cohen (14), Ben, Jeremy, Joselyn Arnon (14), Wendy and Julie Miller at the store (15), and Eric Bloom (15).
