Volt is not a unit of an electric field. Talking about '50 volts' is complete nonsense in a context of an electric field. Also, a magnetic field around a wire

Volt is not a unit of an electric field. Talking about '50 volts' is complete nonsense in a context of an electric field. Also, a magnetic field around a wire will establish if there is a moving charge inside the wire, which can be established with any voltage -- as long as there is current, which is measured in ampere. Electric charge is measured in coulomb and magnetic fields are given in tesla -- so there cannot be a connection if they talk about 'volt'.
I am not saying there isn't any link but I am saying that 'volt' is surely the wrong connection, so this should be taken with utmost caution.

They put ants inside a test apparatus, so the "per meter" part is fixed (by its design) and the voltage is experimentally manipulated. They do use the right units elsewhere in the paper. I imagine this was done to avoid measuring the electric field in the electrode/air/floor/ant medium, which is not exactly homogeneous.
