Abstract
We report a first detailed bacterial inventory from vertical profiles of 60 sampling stations distributed along the salinity gradient of the Baltic Sea, one of world's largest brackish water environments, generated using 454 pyrosequencing of partial (400 bp) 16S rRNA genes. Within the salinity gr...

Abstract
We used Holarctic amphipods of the genus Gammarus to test this hypothesis. We sequenced four genes (5,088 bp) for 289 samples representing 115 Gammarus species. A phylogenetic analysis showed that Gammarus originated from the Tethyan region with a saline ancestry in the Paleocene, and later colonize...

Abstract
We used shallow water CO(2) vents in the Mediterranean Sea as a model system to examine emergent ecosystem responses to ocean acidification in rocky reef communities. We assessed in situ benthic invertebrate communities in three distinct pH zones (ambient, low, and extreme low), which differed in bo...

Abstract
Efficient nutrient removal in decentralized wastewater treatment systems is a challenging task. To improve the removal of organic matter and nitrogen from wastewater, two types of bioreactors using membrane-aerated biofilm reactor (MABR) and microbial fuel cell (MFC) techniques were evaluated. During...

The Kingdom of Saudi Arabia includes fauna from three zoogeographic regions: the Afrotropical, Oriental, and Palaearctic regions. To study the mosquito (Diptera: Culicidae) fauna of these regions in Saudi Arabia, larval collections were made at 15 sites during 2005-2006. Thirty-three species represen...

The result of a survey of ectoparasites infesting bats in southeastern Brazil is presented. Of 181 bats belonging to 16 species, 10 (34.1%) were infested by streblid flies (Streblidae), nine (33.5%) by spinturnicid mites (Spinturnicidae), and five (8.3%) by macronyssid mites (Macronyssidae). One spec...

We know little about the phylogeny and diversity of Tuber species in Japan. We have collected 186 new Tuber ascoma samples in Japan over a 10-year period. The identities and phylogenies of the samples were analyzed by using sequences of four nuclear loci, i.e., internal transcribed spacer (ITS) and...

Dinoflagellates are a major taxonomic group in marine phytoplankton communities in terms of diversity and biomass. Some species are also important because they form blooms and/or produce toxins that may cause diverse problems. The composition of planktonic dinoflagellates of the orders Prorocentrales...
