Does the void environment have a sizable effect on the evolution of dwarf galaxies ?
If yes , the best probes should be the most fragile least massive dwarfs .
We compiled a sample of about one hundred dwarfs with M _ { B } in the range –12 to –18 mag , falling within the nearby Lynx-Cancer void .
The goal is to study their evolutionary parameters – gas metallicity and gas mass-fraction , and to address the epoch of the first substantial episode of Star Formation .
Here we present and discuss the results of O/H measurements in 38 void galaxies , among which several the most metal-poor galaxies are found with the oxygen abundances of 12+log ( O/H ) =7.12-7.3 dex .
