Incipient speciation in Drosophila melanogaster involves chemical signals [PDF]
, 2012 The sensory and genetic bases of incipient speciation between strains of Drosophila melanogaster from Zimbabwe and those from elsewhere are unknown. We studied mating behaviour between eight strains - six from Zimbabwe, together with two cosmopolitan ...

The existence of species rests on a metastable equilibrium between inbreeding and outbreeding [PDF]
, 2011 Background: Speciation corresponds to the progressive establishment of reproductive barriers between groups of individuals derived from an ancestral stock.

Determinations of iron speciation and modelling results of dissolved iron speciation and apparent iron solubility from water samples during METEOR cruise M136 [PDF]
, 2021 The file contains measurements and modelling results of iron (Fe) speciation of water samples collected on the Peruvian shelf and slope region. Determinations of iron speciation were analyzed via Adsorptive Cathodic Stripping Voltammetry (Gledhill and ...

Scientific Reports, 2022 The sibling species An. coluzzii and An. gambiae s.s. are major malaria vectors thought to be undergoing sympatric speciation with gene flow. In the absence of intrinsic post-zygotic isolation between the two taxa, speciation is thought possible through ...

Mate Choice Drives Evolutionary Stability in a Hybrid Complex. [PDF]
PLoS ONE, 2015 Previous studies have shown that assortative mating acts as a driver of speciation by countering hybridization between two populations of the same species (pre-zygotic isolation) or through mate choice among the hybrids (hybrid speciation).

The speciation of the proteome [PDF]
Chemistry Central Journal, 2008 In proteomics a paradox situation developed in the last years. At one side it is basic knowledge that proteins are post-translationally modified and occur in different isoforms. At the other side the protein expression concept disclaims post-translational modifications by connecting protein names directly with function.Optimal proteome coverage is ...

Ecological explanations for (incomplete) speciation [PDF]
, 2009 Divergent natural selection has been shown to promote speciation in many taxa. However, although divergent selection often initiates the process of speciation, it often fails to complete it.

Male‐biased sexual selection, but not sexual dichromatism, predicts speciation in birds [PDF]
, 2021 Sexual selection is thought to shape phylogenetic diversity by affecting speciation or extinction rates. However, the net effect of sexual selection on diversification is hard to predict because many of the hypothesized effects on speciation or ...

Chemical speciation of environmentally significant metals with inorganic ligands Part 2: The Cu2+-OH-, Cl-, CO32-, SO42-, and PO43- systems [PDF]
, 2007 Complex formation between CuII and the common environmental ligands Cl-, OH-, CO32-, SO42-, and PO43- can have a significant effect on CuII speciation in natural waters with low concentrations of organic matter.

Nanomaterials, 2023 Selenium 0 (Se0) is a powerful anti-proliferative agent in cancer research. We investigated the impact of sub-toxic concentrations of Se0 functionalized nanoparticles (SeNPs) on prostate cancer PC-3 cells and determined their intracellular localization ...
