Ecological disruptive selection acting on quantitative loci can drive sympatric speciation
npj Systems Biology and ApplicationsThe process of speciation generates biodiversity. According to the null model of speciation, barriers between populations arise in allopatry, where, prior to biology, geography imposes barriers to gene flow.

Speciation and endemism under the model of island biogeography
, 2009 : Speciation has been considered as a primary process contributing to species diversity, but its contribution to the diversity of local communities has not been fully appreciated. Based on the theory of classic island biogeography, we derived a model for

Study of lead phytoavailability for atmospheric industrial micronic and sub-micronic particles in relation with lead speciation [PDF]
, 2009 Particles from channelled emissions of a battery recycling facility were size-segregated and investigated to correlate their speciation and morphology with their transfer towards lettuce. Microculture experiments carried out with various calcareous soils

Advanced Science, EarlyView.A hierarchically porous AOPIM‐CNT electrode enables uranium harvesting from seawater via adsorption‐promoted electrodeposition. Rapid diffusion and selective adsorption are coupled with electrochemical crystallization and spontaneous detachment, creating a self‐refreshing process that sustains high‐capacity, continuous extraction from ultradilute ...

Advanced Science, EarlyView.Herein, we propose a solar‐powered heavy metal trap (SPHT) for sludge disposal. The indoor experiments demonstrated that the sludge water content decreased from 90 % to 31 %, coupled with a decrease in heavy metal content to 6 % at most. Furthermore, the designed SPHT generated an initial potential of 0.10 V, and monitoring this hydrovoltaic potential ...

Design of a Hollow Fiber Supported Liquid Membrane System for Zn Speciation in Natural Waters
Membranes, 2018 A supported liquid membrane-hollow fiber system (HFSLM) has been developed to determine zinc speciation in aquatic environments. The liquid membrane consisted of an organic solution of bis-(2-ethylhexyl)phosphoric acid (D2EHPA) impregnated in the ...

Predictability, an Orrery, and a Speciation Machine: Quest for a Standard Model of Speciation.
Accurate predictions are commonly taken as a hallmark of strong scientific understanding. Yet, we do not seem capable today of making many accurate predictions about biological speciation. Why?

Trémaux on species: A theory of allopatric speciation (and punctuated equilibrium) before Wagner [PDF]
, 2008 Pierre Trémaux’s 1865 ideas on speciation have been unjustly derided following his acceptance by Marx and rejection by Engels, and almost nobody has read his ideas in a charitable light.

Essay: On the close relationship between speciation, inbreeding and recessive mutations.
, 2010 Whilst the principle of adaptive evolution is unanimously recognised as being caused by the process of natural selection favouring the survival and/or reproduction of individuals having acquired new advantageous traits, a consensus has proven much harder
