Origin and evolution of the RIG-I like RNA helicase gene family
Springer Science and Business Media LLC - Tập 9 Số 1 - Trang 85 - 2009
Jun Zou, Ming Xian Chang, Pin Nie, Christopher J. Secombes
Avoid, attack or do both? Behavioral and physiological adaptations in natural enemies faced with novel hosts
Springer Science and Business Media LLC - - 2005
Corinne Vacher, Sam P. Brown, Michael Hochberg
Abstract Background Confronted with well-defended, novel hosts, should an enemy invest in avoidance of these hosts (behavioral adaptation), neutralization of the defensive innovation (physiological adaptation) or both? Although simultaneous in...... hiện toàn bộ
Accounting for horizontal gene transfers explains conflicting hypotheses regarding the position of aquificales in the phylogeny of Bacteria
Springer Science and Business Media LLC - Tập 8 Số 1 - Trang 272 - 2008
Bastien Boussau, Laurent Guéguen, Manolo Gouy
Assessing the evolutionary rate of positional orthologous genes in prokaryotes using synteny data
Springer Science and Business Media LLC - Tập 7 - Trang 1-18 - 2007
Frédéric Lemoine, Olivier Lespinet, Bernard Labedan
Comparison of completely sequenced microbial genomes has revealed how fluid these genomes are. Detecting synteny blocks requires reliable methods to determining the orthologs among the whole set of homologs detected by exhaustive comparisons between each pair of completely sequenced genomes. This is a complex and difficult problem in the field of comparative genomics but will help to better unders...... hiện toàn bộ
Ecological divergence and conservatism: spatiotemporal patterns of niche evolution in a genus of livebearing fishes (Poeciliidae: Xiphophorus)
Springer Science and Business Media LLC - Tập 16 - Trang 1-16 - 2016
Zachary W. Culumber, Michael Tobler
Ecological factors often have a strong impact on spatiotemporal patterns of biodiversity. The integration of spatial ecology and phylogenetics allows for rigorous tests of whether speciation is associated with niche conservatism (constraints on ecological divergence) or niche divergence. We address this question in a genus of livebearing fishes for which the role of sexual selection in speciation ...... hiện toàn bộ
Unraveling historical introgression and resolving phylogenetic discord within Catostomus (Osteichthys: Catostomidae)
Springer Science and Business Media LLC - Tập 18 - Trang 1-16 - 2018
Max R. Bangs, Marlis R. Douglas, Steven M. Mussmann, Michael E. Douglas
Porous species boundaries can be a source of conflicting hypotheses, particularly when coupled with variable data and/or methodological approaches. Their impacts can often be magnified when non-model organisms with complex histories of reticulation are investigated. One such example is the genus Catostomus (Osteichthys, Catostomidae), a freshwater fish clade with conflicting morphological and mito...... hiện toàn bộ
Consequences of the historical demography on the global population structure of two highly migratory cosmopolitan marine fishes: the yellowfin tuna (Thunnus albacares) and the skipjack tuna (Katsuwonus pelamis)
Springer Science and Business Media LLC - Tập 5 - Trang 1-9 - 2005
Bert Ely, Jordi Viñas, Jaime R Alvarado Bremer, Donna Black, Luciano Lucas, Kelly Covello, Alexis V Labrie, Eric Thelen
Yellowfin and skipjack tuna are globally distributed in the world's tropical and sub-tropical oceans. Since little, if any, migration of these fishes occurs between the Atlantic and Indo-Pacific Oceans, one might expect to see genetic differences between sub-populations in these ocean basins. However, yellowfin and skipjack tuna have extremely large population sizes. Thus, the rate of genetic drif...... hiện toàn bộ
On trends and patterns in macroevolution: Williston’s law and the branchiostegal series of extant and extinct osteichthyans
Springer Science and Business Media LLC - Tập 19 - Trang 1-11 - 2019
Eduardo Ascarrunz, Marcelo R. Sánchez-Villagra, Ricardo Betancur-R, Michel Laurin
The branchiostegal series consists of an alignment of bony elements in the posterior portion of the skull of osteichthyan vertebrates. We trace the evolution of the number of elements in a comprehensive survey that includes 440 extant and 66 extinct species. Using a newly updated actinopterygian tree in combination with phylogenetic comparative analyses, we test whether osteichthyan branchiostegal...... hiện toàn bộ
Substrate cross-feeding affects the speed and trajectory of molecular evolution within a synthetic microbial assemblage
Springer Science and Business Media LLC - Tập 19 - Trang 1-11 - 2019
Elin E. Lilja, David R. Johnson
Substrate cross-feeding occurs when one organism partially consumes a primary substrate into one or more metabolites while other organisms then consume the metabolites. While pervasive within microbial communities, our knowledge about the effects of substrate cross-feeding on microbial evolution remains limited. To address this knowledge gap, we experimentally evolved isogenic nitrite (NO2−) cross...... hiện toàn bộ
Comparative genomics of Thermus thermophilus and Deinococcus radiodurans: divergent routes of adaptation to thermophily and radiation resistance
Springer Science and Business Media LLC - Tập 5 - Trang 1-22 - 2005
Marina V Omelchenko, Yuri I Wolf, Elena K Gaidamakova, Vera Y Matrosova, Alexander Vasilenko, Min Zhai, Michael J Daly, Eugene V Koonin, Kira S Makarova
Thermus thermophilus and Deinococcus radiodurans belong to a distinct bacterial clade but have remarkably different phenotypes. T. thermophilus is a thermophile, which is relatively sensitive to ionizing radiation and desiccation, whereas D. radiodurans is a mesophile, which is highly radiation- and desiccation-resistant. Here we present an in-depth comparison of the genomes of these two related b...... hiện toàn bộ
