    Description: Tribolium castaneum is a member of the most species-rich eukaryotic order, a powerful model organism for the study of generalized insect development, and an important pest of stored agricultural products. We describe its genome sequence here. This omnivorous beetle has evolved the ability to interact with a diverse chemical environment, as shown by large expansions in odorant and gustatory receptors, as well as P450 and other detoxification enzymes. Development in Tribolium is more representative of other insects than is Drosophila, a fact reflected in gene content and function. For example, Tribolium has retained more ancestral genes involved in cell-cell communication than Drosophila, some being expressed in the growth zone crucial for axial elongation in short-germ development. Systemic RNA interference in T. castaneum functions differently from that in Caenorhabditis elegans, but nevertheless offers similar power for the elucidation of gene function and identification of targets for selective insect control.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tribolium Genome Sequencing Consortium -- Richards, Stephen -- Gibbs, Richard A -- Weinstock, George M -- Brown, Susan J -- Denell, Robin -- Beeman, Richard W -- Gibbs, Richard -- Bucher, Gregor -- Friedrich, Markus -- Grimmelikhuijzen, Cornelis J P -- Klingler, Martin -- Lorenzen, Marce -- Roth, Siegfried -- Schroder, Reinhard -- Tautz, Diethard -- Zdobnov, Evgeny M -- Muzny, Donna -- Attaway, Tony -- Bell, Stephanie -- Buhay, Christian J -- Chandrabose, Mimi N -- Chavez, Dean -- Clerk-Blankenburg, Kerstin P -- Cree, Andrew -- Dao, Marvin -- Davis, Clay -- Chacko, Joseph -- Dinh, Huyen -- Dugan-Rocha, Shannon -- Fowler, Gerald -- Garner, Toni T -- Garnes, Jeffrey -- Gnirke, Andreas -- Hawes, Alica -- Hernandez, Judith -- Hines, Sandra -- Holder, Michael -- Hume, Jennifer -- Jhangiani, Shalini N -- Joshi, Vandita -- Khan, Ziad Mohid -- Jackson, LaRonda -- Kovar, Christie -- Kowis, Andrea -- Lee, Sandra -- Lewis, Lora R -- Margolis, Jon -- Morgan, Margaret -- Nazareth, Lynne V -- Nguyen, Ngoc -- Okwuonu, Geoffrey -- Parker, David -- Ruiz, San-Juana -- Santibanez, Jireh -- Savard, Joel -- Scherer, Steven E -- Schneider, Brian -- Sodergren, Erica -- Vattahil, Selina -- Villasana, Donna -- White, Courtney S -- Wright, Rita -- Park, Yoonseong -- Lord, Jeff -- Oppert, Brenda -- Brown, Susan -- Wang, Liangjiang -- Weinstock, George -- Liu, Yue -- Worley, Kim -- Elsik, Christine G -- Reese, Justin T -- Elhaik, Eran -- Landan, Giddy -- Graur, Dan -- Arensburger, Peter -- Atkinson, Peter -- Beidler, Jim -- Demuth, Jeffery P -- Drury, Douglas W -- Du, Yu-Zhou -- Fujiwara, Haruhiko -- Maselli, Vincenza -- Osanai, Mizuko -- Robertson, Hugh M -- Tu, Zhijian -- Wang, Jian-jun -- Wang, Suzhi -- Song, Henry -- Zhang, Lan -- Werner, Doreen -- Stanke, Mario -- Morgenstern, Burkhard -- Solovyev, Victor -- Kosarev, Peter -- Brown, Garth -- Chen, Hsiu-Chuan -- Ermolaeva, Olga -- Hlavina, Wratko -- Kapustin, Yuri -- Kiryutin, Boris -- Kitts, Paul -- Maglott, Donna -- Pruitt, Kim -- Sapojnikov, Victor -- Souvorov, Alexandre -- Mackey, Aaron J -- Waterhouse, Robert M -- Wyder, Stefan -- Kriventseva, Evgenia V -- Kadowaki, Tatsuhiko -- Bork, Peer -- Aranda, Manuel -- Bao, Riyue -- Beermann, Anke -- Berns, Nicola -- Bolognesi, Renata -- Bonneton, Francois -- Bopp, Daniel -- Butts, Thomas -- Chaumot, Arnaud -- Denell, Robin E -- Ferrier, David E K -- Gordon, Cassondra M -- Jindra, Marek -- Lan, Que -- Lattorff, H Michael G -- Laudet, Vincent -- von Levetsow, Cornelia -- Liu, Zhenyi -- Lutz, Rebekka -- Lynch, Jeremy A -- da Fonseca, Rodrigo Nunes -- Posnien, Nico -- Reuter, Rolf -- Schinko, Johannes B -- Schmitt, Christian -- Schoppmeier, Michael -- Shippy, Teresa D -- Simonnet, Franck -- Marques-Souza, Henrique -- Tomoyasu, Yoshinori -- Trauner, Jochen -- Van der Zee, Maurijn -- Vervoort, Michel -- Wittkopp, Nadine -- Wimmer, Ernst A -- Yang, Xiaoyun -- Jones, Andrew K -- Sattelle, David B -- Ebert, Paul R -- Nelson, David -- Scott, Jeffrey G -- Muthukrishnan, Subbaratnam -- Kramer, Karl J -- Arakane, Yasuyuki -- Zhu, Qingsong -- Hogenkamp, David -- Dixit, Radhika -- Jiang, Haobo -- Zou, Zhen -- Marshall, Jeremy -- Elpidina, Elena -- Vinokurov, Konstantin -- Oppert, Cris -- Evans, Jay -- Lu, Zhiqiang -- Zhao, Picheng -- Sumathipala, Niranji -- Altincicek, Boran -- Vilcinskas, Andreas -- Williams, Michael -- Hultmark, Dan -- Hetru, Charles -- Hauser, Frank -- Cazzamali, Giuseppe -- Williamson, Michael -- Li, Bin -- Tanaka, Yoshiaki -- Predel, Reinhard -- Neupert, Susanne -- Schachtner, Joachim -- Verleyen, Peter -- Raible, Florian -- Walden, Kimberly K O -- Angeli, Sergio -- Foret, Sylvain -- Schuetz, Stefan -- Maleszka, Ryszard -- Miller, Sherry C -- Grossmann, Daniela -- BBS/B/12067/Biotechnology and Biological Sciences Research Council/United Kingdom -- BBS/B/12067/2/Biotechnology and Biological Sciences Research Council/United Kingdom -- R01 GM058634/GM/NIGMS NIH HHS/ -- R01 HD029594/HD/NICHD NIH HHS/ -- R01 HD029594-16/HD/NICHD NIH HHS/ -- U54 HG003273/HG/NHGRI NIH HHS/ -- Intramural NIH HHS/ -- England -- Nature. 2008 Apr 24;452(7190):949-55. doi: 10.1038/nature06784.

    Description: Invasive species that proliferate after colonizing new habitats have a negative environmental and economic impact. The reason why some species become successful invaders, whereas others, even closely related species, remain noninvasive is often unclear. The harlequin ladybird Harmonia axyridis, introduced for biological pest control, has become an invader that is outcompeting indigenous ladybird species in many countries. Here, we show that Harmonia carries abundant spores of obligate parasitic microsporidia closely related to Nosema thompsoni. These microsporidia, while not harming the carrier Harmonia, are lethal pathogens for the native ladybird Coccinella septempunctata. We propose that intraguild predation, representing a major selective force among competing ladybird species, causes the infection and ultimate death of native ladybirds when they feed on microsporidia-contaminated Harmonia eggs or larvae.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Vilcinskas, Andreas -- Stoecker, Kilian -- Schmidtberg, Henrike -- Rohrich, Christian R -- Vogel, Heiko -- New York, N.Y. -- Science. 2013 May 17;340(6134):862-3. doi: 10.1126/science.1234032.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Phytopathology and Applied Zoology, Heinrich-Buff-Ring 26-32, Justus-Liebig-University of Giessen, D-35392 Giessen, Germany. andreas.vilcinskas@agrar.uni-giessen.de〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23687046" target="_blank"〉PubMed〈/a〉

    Description: Comments by de Jong et al., Solter et al., and Sloggett question the ecological relevance of the abundant microsporidia found in the invasive ladybird Harmonia axyridis. We contend that there is abundant evidence that native ladybirds feed on H. axyridis eggs and that interspecific microsporidial transfer is a common phenomenon, supporting the proposed role of these parasites as biological weapons.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Vilcinskas, Andreas -- Stoecker, Kilian -- Schmidtberg, Henrike -- Rohrich, Christian R -- Vogel, Heiko -- New York, N.Y. -- Science. 2013 Sep 20;341(6152):1342. doi: 10.1126/science.1242484.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institute of Phytopathology and Applied Zoology, Heinrich-Buff-Ring 26-32, Justus-Liebig-University of Giessen, D-35392 Giessen, Germany. andreas.vilcinskas@agrar.uni-giessen.de〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/24052293" target="_blank"〉PubMed〈/a〉

    Description: Safflower ( Carthamus tinctorius L.) serves as a reference dicot for investigation of defense mechanisms in Asteraceae due to abundant secondary metabolites and high resistance/tolerance to environmental stresses. In plants, phenylpropanoid and flavonoid pathways are considered as two central defense signaling cascades in stress conditions. Here, we describe the isolation of two major genes in these pathways, phenylalanine ammonia-lyase (CtPAL) and chalcone synthase (CtCHS) in safflower along with monitoring their expression profiles in different stress circumstances. The amino acid sequence of isolated region of CtPAL possesses maximum identity up to 96% to its ortholog in Cynara scolymus , while that of CtCHS retains the highest identity to its ortholog in Callistephus chinensis up to 96%. Experiments for gene expression profiling of CtPAL and CtCHS were performed after treatment of seedlings with 0.1 and 1 mM salicylic acid (SA), wounding, and salinity stress. The results of semi-quantitative RT-PCR revealed that both CtPAL and CtCHS genes are further responsive to higher concentration of SA with dissimilar patterns. Regarding wounding stress, CtPAL gets slightly induced upon injury at 3 hours after treatment (hat), while CtCHS gets greatly induced at 3 hat and levels off gradually afterward. Upon salinity stress, CtPAL displays a similar expression pattern by getting slightly induced at 3 hat, but CtCHS exhibits a biphasic expression profile with two prominent peaks at 3 and 24 hat. These results substantiate the involvement of phenylpropanoid and particularly flavonoids pathways in safflower during wounding and especially salinity stress.

    Notes: Abstract— Simple morphological characteristics and fish assemblage data were collected in representative numbers from 12 inland waterways in the northeastern lowlands of Germany between 1992 and 1995. Fish abundance data were pooled and classified into three main groups: perch Perca fluviatilis (L.), roach Rutilus rutilus (L.) and other species. Spearman rank correlations between fish abundance and type of embankment revealed that perch showed a statistically significant numerical dominance in waterways consisting predominately of an artificial shoreline, suggesting that perch may be used as an indicator of the structural degradation of watercourses.

    Description: Nitrification is a fundamental component of the global nitrogen cycle and leads to significant fertilizer loss and atmospheric and groundwater pollution. Nitrification rates in acidic soils (pH 〈 5.5), which comprise 30% of the world's soils, equal or exceed those of neutral soils. Paradoxically, autotrophic ammonia oxidizing bacteria and archaea, which perform the first stage in nitrification, demonstrate little or no growth in suspended liquid culture below pH 6.5, at which ammonia availability is reduced by ionization. Here we report the discovery and cultivation of a chemolithotrophic, obligately acidophilic thaumarchaeal ammonia oxidizer, “Candidatus Nitrosotalea devanaterra,” from an acidic agricultural soil. Phylogenetic analysis places the organism within a previously uncultivated thaumarchaeal lineage that has been observed in acidic soils. Growth of the organism is optimal in the pH range 4 to 5 and is restricted to the pH range 4 to 5.5, unlike all previously cultivated ammonia oxidizers. Growth of this organism and associated ammonia oxidation and autotrophy also occur during nitrification in soil at pH 4.5. The discovery of Nitrosotalea devanaterra provides a previously unsuspected explanation for high rates of nitrification in acidic soils, and confirms the vital role that thaumarchaea play in terrestrial nitrogen cycling. Growth at extremely low ammonia concentration (0.18 nM) also challenges accepted views on ammonia uptake and metabolism and indicates novel mechanisms for ammonia oxidation at low pH.

    Description: The erosion of biodiversity is among our biggest challenges, as we face the risk of losing close to one million plant and animal species within the coming decades1. Despite numerous and ambitious international agreements that have been reached over several decades, ecosystem degradation leading to biodiversity decline has continued — and even accelerated — in almost all domains of life across marine, freshwater and terrestrial systems2. Indeed, planetary integrity and ecosystem services are now at risk of irreversible changes, with severe consequences for human wellbeing3. The main drivers of global biodiversity decline include habitat degradation and loss caused by changes in land and water use, direct exploitation of organisms, climate change, invasion by non-native species and chemical pollution4. However, our understanding of these drivers, single and in concert, often seems to be too rudimentary to adequately guide mitigation strategies that would be compatible with human activities. Here we argue for better integration of chemical pollution alongside other drivers in research that assesses biodiversity impacts.
