Molecularly Imprinted Polymers for Dispersive (Micro)Solid Phase Extraction: A Review
Separations, 2021 The review describes the development of batch solid phase extraction procedures based on dispersive (micro)solid phase extraction with molecularly imprinted polymers (MIPs) and magnetic MIPs (MMIPs).

Defining the speciation continuum
Evolution; international journal of organic evolution, 2021 A primary roadblock to our understanding of speciation is that it usually occurs over a timeframe that is too long to study from start to finish. The idea of a speciation continuum provides something of a solution to this problem; rather than observing ...

eLife, 2020 Zinc and copper are involved in neuronal differentiation and synaptic plasticity but the molecular mechanisms behind these processes are still elusive due in part to the difficulty of imaging trace metals together with proteins at the synaptic level.

Mass of genes rather than master genes underlie the genomic architecture of amphibian speciation
Proceedings of the National Academy of Sciences of the United States of America, 2021 Significance Reproductive isolation is instrumental to the formation of new species (speciation), but it remains largely enigmatic how many incompatibilities are required to prevent hybridization and where they lie across the genome. By studying patterns

Invasive species and biodiversity crises: testing the link in the late devonian. [PDF]
PLoS ONE, 2010 During the Late Devonian Biodiversity Crisis, the primary driver of biodiversity decline was the dramatic reduction in speciation rates, not elevated extinction rates; however, the causes of speciation decline have been previously unstudied.
