Published in 2022 at "Biotechnology Progress"

DOI: 10.1002/btpr.3311

Abstract: Cell culture media metal content is critical in mammalian cell growth and monoclonal antibody productivity. The variability in metal concentrations has multiple sources of origin. As such, there is a need to analyze media before,… read more here.

Published in 2018 at "Ecology and Evolution"

DOI: 10.1002/ece3.3770

Abstract: Abstract Tephroseris longifolia agg. is a complex group of outcrossing perennials distributed throughout Central Europe. Recent morphological study revealed six morphotypes corresponding to five previously distinguished subspecies, together with Alpine and Pannonian morphotypes of T.… read more here.

Published in 2019 at "Ecology and Evolution"

DOI: 10.1002/ece3.5284

Abstract: Abstract Determining the factors promoting speciation is a major task in ecological and evolutionary research and can be aided by phylogeographic analysis. The Qinling–Daba Mountains (QDM) located in central China form an important geographic barrier… read more here.

Published in 2021 at "Ecology and Evolution"

DOI: 10.1002/ece3.7511

Abstract: Abstract Although speciation dynamics have been described for several taxonomic groups in distinct geographic regions, most macroevolutionary studies still lack a detailed mechanistic view on how or why speciation rates change. To help partially fill… read more here.

Published in 2022 at "Ecology and Evolution"

DOI: 10.1002/ece3.8341

Abstract: Abstract The species‐range size distribution is a product of speciation, transformation of range‐sizes, and extinction. Previous empirical studies showed that it has a left‐skewed lognormal‐like distribution. We developed a new mathematical framework to study species‐range‐size… read more here.

Published in 2022 at "Ecology and Evolution"

DOI: 10.1002/ece3.8834

Abstract: Abstract The study of mechanisms that generate new species is considered fundamental for broad areas of ecology and evolution. Speciation is a continuous process in which reproductive isolation is established, and it is of fundamental… read more here.

Published in 2022 at "Ecology and Evolution"

DOI: 10.1002/ece3.9321

Abstract: Abstract We have seen an explosive increase of plant plastid genome (plastome) sequences in the last decade, and the view that sequence variation in plastomes is maintained by the mutation‐drift balance has been challenged by… read more here.

Published in 2022 at "Ecology and Evolution"

DOI: 10.1002/ece3.9341

Abstract: Speciation in the marine environment is challenged by the wide geographic distribution of many taxa and potential for high rates of gene flow through larval dispersal mechanisms. Depth has recently been proposed as a potential… read more here.

Published in 2022 at "Journal of the science of food and agriculture"

DOI: 10.1002/jsfa.12292

Abstract: BACKGROUND Previous studies have demonstrated that in contrast to the properties of food-derived copper, water-derived copper exerts neurotoxic effects and exhibits different speciation during digestion. The cellular uptake efficiencies of different speciation of copper are… read more here.
