In amphibians, intra- or interspecific chemical cues are an important source of information about possible predation risk. In anuran tadpoles, this information causes changes at different levels including behavior, morph...

The coalescence process of two nanoparticles to yield a core-shell structure is analyzed by a well-tempered metadynamics procedure. This methodology has been shown to be useful in understanding the present phenomenon in ...

The Paranapiacaba Mountains are a region of Brazil where the stonefly fauna is relatively well known. Despite this, there are still gaps in knowledge that need to be filled. In this study, through field sampling and mole...
