Variation in Hsp70 levels after cold shock : Signs of evolutionary responses to thermal selection among Leptinotarsa decemlineata populations
(Public Library of Science, 2012)
Individuals of widely spread species are expected to show local adaption in temperature tolerance as they encounter a range of thermal conditions. We tracked thermal adaptations of the Colorado potato beetle (Leptinotarsa ...
Variation in mortality among populations is higher for pymetrozine than for imidacloprid and spiromesifen in Trialeurodes vaporariorum in greenhouses in Finland
(John Wiley & Sons Ltd., 2014)
Abstract. BACKGROUND: Insecticide resistance in Trialeurodes vaporariorum
W. is unknown in the species’ northern distribution range where it inhabits mainly commercial greenhouses. Resistance development in whiteflies ...
Variation in parasite resistance of Arctic charr, Salvelinus alpinus, between and within sympatric morphs
(Wiley-Blackwell, 2021)
Genetic variation in resistance against parasite infections is a predominant feature in host–parasite systems. However, mechanisms maintaining genetic polymorphism in resistance in natural host populations are generally ...
Variation in the COI gene of the freshwater pearl mussel Margaritifera margaritifera from River Vuokkijoki
(Pleiades Publishing; Russian Academy of Sciences, 2017)
The freshwater pearl mussel Margaritifera margaritifera L. is one of the most endangered freshwater mussels in the world. Effective conservation of threatened species requires not only ecological, but also genetic information ...
Variation in ω-3 and ω-6 Polyunsaturated Fatty Acids Produced by Different Phytoplankton Taxa at Early and Late Growth Phase
(MDPI, 2020)
Phytoplankton synthesizes essential ω-3 and ω-6 polyunsaturated fatty acids (PUFA) for consumers in the aquatic food webs. Only certain phytoplankton taxa can synthesize eicosapentaenoic (EPA; 20:5ω3) and docosahexaenoic ...
Variation of fundamental constants and 229Th
(World Scientific, 2017)
The first excited state of the nucleus229Th has an exceptionally small excitation energy of7.8 eV, which is expected to be very sensitive to changes in the fine structure constant α.A small difference in the Coulomb energies ...
Variation of lattice constant and cluster formation in GaAsBi
(American Institute of Physics, 2013)
We investigate the structural properties of GaAsBi layers grown by molecular beam epitaxy on
GaAs at substrate temperatures between 220–315 C. Irrespective of the growth temperature, the
structures exhibited similar Bi ...
Variational Approximations for Generalized Linear Latent Variable Models
(American Statistical Association, 2017)
Generalized linear latent variable models (GLLVMs) are a powerful class of models for understanding the relationships among multiple, correlated responses. Estimation, however, presents a major challenge, as the marginal ...
Varying definitions of abundance and incomplete assemblages challenge the generality of the interspecific abundance-distribution relationships
(Finnish Zoological Botanical Publishing Board, 2011)
Vascular endothelial growth factor-A and platelet-derived growth factor-B combination gene therapy prolongs angiogenic effects via recruitment of interstitial mononuclear cells and paracrine effects rather than improved pericyte coverage of angiogenic vessels
(2008)
Vessel stabilization and the inhibition of side effects such as tissue edema are essential in angiogenic gene therapy. Thus, combination gene transfers stimulating both endothelial cell and pericyte proliferation have ...
