The latitudinal variation in amphibian speciation rates revisited

Communications Biology
Speciation can increase regional species richness, however, our knowledge of how and why speciation rates vary across space is still incomplete. Using comprehensive information on species distributions and their phylogenetic relationships, we describe ...

Co-transport of Pb (II) and Cd (II) in saturated porous media: effects of colloids, flow rate and grain size

Chemical Speciation & Bioavailability, 2018
The transport of Pb(II) or Cd(II) in subsurface has been studied in the literature; however; their co-transport in porous media in presence of colloids has not been clearly understood.

One‐Step, High‐Removal‐Rate and Low‐Damage Chemical Mechanical Polishing of InP Enabled by Hydrolysis Activated PF6− with In Situ Fluoride Passivation

Advanced Science, EarlyView.
In this work, we propose a CMP method for InP using NH4PF₆, which hydrolyzes under In3+ catalysis to form reactive species. These convert InP into low‐binding‐energy fluorides, facilitating removal and dissolution. The process delivers high material removal rates, smooth surfaces, and fluorine passivation that lowers defect density and improves ...

Four new species of Schilbetrema (Monogenea: Dactylogyridae) from Schilbe spp. (Siluriformes: Schilbeidae) in the Sanaga River (Sanaga Basin) and Boumba River (Congo Basin) in Cameroon [PDF]

Zoologia (Curitiba)
Monogeneans are among the main parasites affecting aquaculture worldwide. The present study describes four new species belonging to Schilbetrema, which is only known from African catfishes.

Investigating the molecular basis of adaptation and speciation in divergent populations

, 2013
The creation of biodiversity involves the evolution of new species. Recent trends in the study of speciation have increased the emphasis on the role of ecology in adaptation and the evolution of reproductive isolation.

Al(III) and Fe(III) binding by humic substances in freshwaters, and implications for trace metal speciation. [PDF]

, 2002
Published experimental data for Al(III) and Fe(III) binding by fulvic and humic acids can be explained approximately by the Humic Ion-Binding Model VI. The model is based on conventional equilibrium reactions involving protons, metal aquo ions and their ...

Speciation without Species: A Final Word [PDF]

, 2018
Here I present the several models currently popular for understanding speciation in prokaryotes, in particular bacteria. I will argue that “speciation”, as a process or collection of independent but interacting processes sometimes serving to form ...

Advanced Dental Composite Technology via Bisilanized Dual‐Action Nanofillers for Biofilm Control

Advanced Science, EarlyView.
A multimodal research strategy has led to the development of an innovative resin‐based composite (RBC) with dual antibacterial action. The S_CM‐RBC formula showed strong antibiofilm activity, excellent mechanical strength, and biosafety. It effectively controlled oral bacteria in prevention of caries recurrence, and maintained pulp health in a rat ...

Interfacial Polysulfide Confinement via Spatially Controlled Sulfonated Metal–Organic Polyhedra Coatings in Lithium–Sulfur Batteries

Advanced Science, EarlyView.
Spatially controlled sulfonated metal–organic polyhedra (SMOP) coating on sulfur‐loaded hollow carbon spheres form ultrathin, conformal interfacial barriers that selectively confine soluble polysulfides, stabilize sulfur redox, and suppress shuttle reactions.
