Although modern climate conditions in the 26 June 2009 Central Kenya Rift are very similar for these basins, hydrology and hydrochemistry of present-day lakes Accepted 9 July 2009 Nakuru, Elmenteita and Naivasha contrast dramatically due to tectonically controlled differences in basin geometries, catchment size, and fluvial processes. In this study, we use eighteen 14Cand40Ar/39Ar dated fluvio-lacustrine sedimentary sections to unravel the spatiotemporal evolution of the lake basins in response to tectonic and climatic influences.

Oceanic island biota generally present high percentages of endemic species, and the vulnerability of these species is higher than those of the continents. The objective of this work was to carry out a survey of the Collembola species of the order Poduromorpha in the Brazilian oceanic islands and synthesize a distribution list of this order for Brazil. Our results reveal four new species of Collembola Poduromorpha for Brazilian oceanic islands that may be useful for the conservation strategies of these island regions and a contributor to the knowledge of the order in Brazil.

Ascidians from Rocas Atoll, Northeast Brazil
ORIGINAL RESEARCH published: 16 June 2015 doi: 10.3389/fmars.2015.00039 Ascidians from Rocas Atoll, northeast Brazil Sandra V. Paiva 1, Ronaldo R. de Oliveira Filho 1 and Tito M. da Cruz Lotufo 1, 2* 1 Graduate Program in Tropical Marine Sciences, Universidade Federal do Ceará, Fortaleza, Brazil, 2 Departament of Biological Oceanography, Instituto Oceanográfico, Universidade de São Paulo, São Paulo, Brazil Rocas Atoll is the only one of its kind in the South Atlantic—and the first Brazilian marine biological reserve. This is the first report about the ascidians from Rocas. A total of 12 species were found, 5 of them not hitherto described: Ascidia viridina sp. nov., Didemnum rochai sp. nov., Leptoclinides crocotulus sp. nov., Polysyncraton maurizeliae sp. nov., and Trididemnum rocasensis sp. nov. One Caribbean species, Didemnum halimedae, was also discovered in the region for the first time. Further, this is the first record of Didemnum digestum in the Atlantic. The results indicate a high degree of endemism in the ascidian fauna from Rocas Atoll, where didemnids are presently the most important members. Keywords: Ascidiacea, Tunicata, biodiversity, coral reef, taxonomy Edited by: Wei-Jen Chen, National Taiwan University, Taiwan Introduction Reviewed by: Greg W. Rouse, Ascidians are benthic marine invertebrates that are present throughout the marine environments University of California San Diego, from the intertidal to the deep sea. Currently, over 3000 species have been formally described USA (Lambert, 2005), but only 461 have been found in the Atlantic Ocean (Rocha et al., 2012). Francoise Monniot, Muséum National d’Histoire Naturelle, Despite their importance as one of the major components of benthic communities, their France presence is still ignored in many regions due to the lack of collections or specialists. -

Of those that have been assessed on the IUCN Red List, 63% are considered threatened, and 10% are critically endangered, with ca. 42% of all known turtle species threatened. Without directed strategic conservation planning, a significant portion of turtle diversity could be lost over the next century. Toward that conservation effort, we compiled museum and literature occurrence records for all of the world’s tortoises and freshwater turtle species to determine their distributions and identify priority regions for conservation. -

Colonization and Growth of Crustose Coralline Algae (Corallinales, Rhodophyta) on the Rocas Atoll
BRAZILIAN JOURNAL OF OCEANOGRAPHY, 53(3/4):147-156, 2005 Colonization and growth of crustose coralline algae (Corallinales, Rhodophyta) on the Rocas Atoll Alexandre Bigio Villas Bôas1*; Marcia A. de O.Figueiredo 2 & Roberto Campos Villaça 1 1Universidade Federal Fluminense (Caixa Postal 100644, 24001-970Niterói, RJ, Brasil) 2Instituto de Pesquisas Jardim Botânico do Rio de Janeiro (Rua Pacheco Leão 915, 22460-030 Rio de Janeiro, RJ, Brasil) *[email protected] A B S T R A C T Crustose coralline algae play a fundamental role in reef construction all over the world. The aims fo this study were to identify and estimate the abundance of the dominant crustose coralline algae in shallow reef habitats, measuring their colonization, growth rates and productivity. Crusts sampled from different habitats were collected on leeward and windward reefs. Discs made of epoxy putty were fixed on the reef surface to follow coralline colonization and discs containing the dominant coralline algae were fixed on different habitats to measure the crusts’ marginal growth. The primary production experiments followed the clear and dark bottle method for dissolved oxygen reading. Porolithon pachydermum was confirmed as the dominant crustose coralline alga on the Rocas Atoll. The non-cryptic flat form of P. pachydermum showed a faster growth rate on the leeward than on the windward reef. This form also had a faster growth rate on the reef crest (0.05 mm.day-1) than on the reef flat (0.01 mm.day-1). The cryptic protuberant form showed a trend, though not significant, towards a faster growth rate on the reef crest and in tidal pools than on the reef flat. -

Biogeochemistry of Kenyan Rift Valley Lake Sediments
Geophysical Research Abstracts Vol. 15, EGU2013-9512, 2013 EGU General Assembly 2013 © Author(s) 2013. CC Attribution 3.0 License. Biogeochemistry of Kenyan Rift Valley Lake Sediments Sina Grewe (1) and Jens Kallmeyer (2) (1) University of Potsdam, Institute of Earth and Environmental Sciences, Geomicrobiology Group, Potsdam, Germany ([email protected]), (2) German Research Centre for Geosciences, Section 4.5 Geomicrobiology, Potsdam, Germany ([email protected]) The numerous lakes in the Kenyan Rift Valley show strong hydrochemical differences due to their varying geologic settings. There are freshwater lakes with a low alkalinity like Lake Naivasha on the one hand and very salt-rich lakes with high pH values like Lake Logipi on the other. It is known that the underlying lake sediments are influenced by the lake chemistry and by the microorganisms in the sediment. The aim of this work is to provide a biogeochemical characterization of the lake sediments and to use these data to identify the mechanisms that control lake chemistry and to reconstruct the biogeochemical evolution of each lake. The examined rift lakes were Lakes Logipi and Eight in the Suguta Valley, Lakes Baringo and Bogoria south of the valley, as well as Lakes Naivasha, Oloiden, and Sonachi on the Kenyan Dome. The porewater was analysed for different ions and hydrogen sulphide. Additionally, alkalinity and salinity of the lake water were determined as well as the cell numbers in the sediment, using fluorescent microscopy. The results of the porewater analysis show that the overall chemistry differs considerably between the lakes. In some lakes, concentrations of fluoride, chloride, sulphate, and/or hydrogen sulphide show strong concentration gradients with depth, whereas in other lakes the concentrations show only minor variations. -

Nevertheless, the Neotropics today harbour roughly three times more flowering plant species than tropical Africa. The role of evolutio- nary history in generating this pattern remains poorly understood, mostly because collecting biological specimens in the tropics is difficult. -

VALLEY 1Department of Geology and Geophysics, University of Wisconsin, Madison, WI, USA 2Institute of Volcanic Geology and Geochemistry, Petropavlovsk-Kamchatsky, Russia 3Geologisk Institut, University of Copenhagen, Copenhagen, Denmark (Received March 20, 2003; accepted in revised form July 16, 2003) Abstract—We present the results of a regional study of oxygen and Sr-Nd-Pb isotopes of Pleistocene to Recent arc volcanism in the Kamchatka Peninsula and the Kuriles, with emphasis on the largest caldera- forming centers. The ␦18O values of phenocrysts, in combination with numerical crystallization modeling (MELTS) and experimental fractionation factors, are used to derive best estimates of primary values for ␦18O(magma). Magmatic ␦18O values span 3.5‰ and are correlated with whole-rock Sr-Nd-Pb isotopes and major elements. Our data show that Kamchatka is a region of isotopic diversity with high-␦18O basaltic magmas (sampling mantle to lower crustal high-␦18O sources), and low-␦18O silicic volcanism (sampling low-␦18O upper crust). Among one hundred Holocene and Late Pleistocene eruptive units from 23 volcanic centers, one half represents low-␦18O magmas (ϩ4 to 5‰). Most low-␦ 18O magmas are voluminous silicic ignimbrites related to large Ͼ10 km3 caldera-forming eruptions and subsequent intracaldera lavas and domes: Holocene multi-caldera Ksudach volcano, Karymsky and Kurile Lake-Iliinsky calderas, and Late Pleistocene Maly Semyachik, Akademy Nauk, and Uzon calderas.
