    Beschreibung: During expedition EMB201 in the Baltic Sea we investigated the local producers of glycerol dialkyl glycerol tetraethers (GDGT) and their thriving depth by a combined 16S rRNA gene amplicon sequencing/ CARD-FISH and lipidomic approach. Water samples were taken in December 2018 by a pump-CTD, a giant water sampler and with Niskin bottles at the surface, suboxic and sulfidic zones of the Landsort Deep, Fårö Basin and East Gotland Basin. This data set contains the CARD-FISH and lipidomics data, while the 16S rRNA gene sequencing data is available on ENA. Cell abundance was analysed in an aliquot of 40 ml filtered (pore size 0.22 micro m) sea water fixed with particle-free formaldehyde. Archaeal cells on the filters were specifically hybridized via catalysed reporter deposition-fluorescence in situ hybridization (CARD-FISH) using the Cren537 probe. Cells on the hybridized filter were counter-stained with 40,6-diamidin-2-phenylindol (DAPI). For lipid analysis, 150–600 L sea water were filtered with a flow rate of 1.5 L min-1 on pre-ashed, 142-mm-diameter, 0.7µm pore size glass fibre GF/F filters, and frozen at –20 °C. The filters were lyophilized before different extraction methods were used to obtain intact and core GDGTs by ultra-sonification in different solvent mixtures. The combined supernatants were phase separated before analysis by high performance liquid chromatography coupled to tandem mass spectrometry (HPLC-MS2) for intact polar lipids and by high performance liquid chromatography coupled to atmospheric pressure chemical ionization mass spectrometry (HPLC APCI-MS; ThermoScientific) for core GDGTs.

    Beschreibung: Cichlids have evolved into models for studying the evolutionary history of Neotropical fish. Many authors attempted to recover the group's phylogeny using morphological and molecular data, presenting satisfying solutions across a wide range of genera. However, intrageneric relationships remain obscure in a number of genus, potentially complicating species delimitation. Mesonauta presents six distinct species that are highly valued by aquarists. Currently, there is no proposed phylogenetic relationship between its species; however, it has a wide geographic distribution and phenotypic variations, with the possibility of new species not yet described. Species of the genus were delimited using molecular and morphometric data from preserved and deposited species in ichthyological collections. From the six previously described species, COI delimitate different species, since two of them (Mesonauta egregius and M. guyanae) were not corroborated by delimitation analysis and two are putative new species, showing six different species: M. mirificus, M. festivus, Mesonauta sp. “Pantanal”, M. acora, Mesonauta sp. “Amapá” and M. insignis. The results showed a new basis for studies within the genus and further research is needed to understand the wide distribution of M. mirificus. Mesonauta's monophyly was tested and the relationships between species by constructing concatenated cladograms based on molecular characters (COI, 16S) using three phylogenetic methods, from which two main clades were recovered a new species of Mesonauta was described from the Amapá Grande river basin, based on morphological and molecular characteristics, in a region affected by the presence of mercury. This is the first step in investigating the molecular phylogeny of Mesonauta, which showed intrageneric relationships based on molecular data, enabled the description of a new species of the genus and provided information for future research on the evolutionary history of the group.
    Beschreibung: Ciclídeos tornaram-se modelos para o estudo da história evolutiva de peixes da região Neotropical. Muitos autores têm tentado recuperar a filogenia do grupo com dados morfológicos e moleculares, apresentando resoluções satisfatórias entre muitos gêneros. Entretanto, as relações de parentesco intragenéricas ainda permanecem obscuras para vários gêneros, o que pode dificultar até mesmo a delimitação das espécies. Mesonauta apresenta seis espécies válidas, muito apreciadas pelos aquaristas. Atualmente não há nenhuma proposta filogenética de relações entre suas espécies e o gênero apresenta ampla distribuição geográfica e variações fenotípicas, com possíveis espécies novas não descritas. Foram delimitadas as espécies do gênero, a partir de dados moleculares e morfométricos de espécimes conservados e depositados em coleções ictiológicas. Das seis espécies descritas anteriormente, o COI delimita espécies diferentes, uma vez que duas delas (Mesonauta egregius e M. guyanae) não foram corroboradas pela análise de delimitação e duas são supostas espécies novas, mostrando seis diferentes espécies: Mesonauta mirificus, M. festivus, Mesonauta sp. “Pantanal”, M. acora, Mesonauta sp. “Amapá” and M. insignis. Os resultados mostraram uma nova base para estudos dentro do gênero e novas pesquisas são necessárias para entender a ampla distribuição de M. mirificus. Foi testado o monofiletismo de Mesonauta e as relações entre as espécies, com a construção de cladogramas baseados em caracteres moleculares (COI, 16S) utilizando três métodos filogenéticos, dos quais dois clados principais foram recuperados. Uma espécie nova de Mesonauta foi descrita da bacia do rio Amapá Grande, baseada em características morfológicas e moleculares, em uma região afetada pela presença de mercúrio. Este é o primeiro passo na investigação da filogenia molecular de Mesonauta, que mostrou relações intragenéricas baseadas em dados moleculares, possibilitou a descrição de uma espécie nova do gênero e forneceu informações para futuras pesquisas sobre a história evolutiva do grupo.

    Beschreibung: A revision of Leptopus and Notoleptopus (Phyllanthaceae tribe Poranthereae) in Malesia is presented. Both genera are present with a single species in Malesia, L. australis and N. decasnei, respectively. Phylogenetically the two genera are distinct, but morphologically their differences are minimal. Nomenclature, descriptions, distributions and various notes are presented, just as a technical drawing of both species.

    Beschreibung: Detailed morphological and molecular research has led to the conclusion that the majority of the species of the genus Brachiaria have to move to the much smaller genus Urochloa. Although many of the necessary new combinations were made, in Africa a fair number of accepted species still do not yet have a name within Urochloa. Following work on WestAfrica, CentralAfrica and Madagascar, this paper now provides these new combinations for the remaining sub-SaharanAfrican species, as well as a full synonymy for all EastAfrican ones, including typification. In total, the paper deals with 40 species, for 12 of these new combinations are created, while 55 lectotypes and one neotype of both accepted names and synonyms are designated.
