  Gyrokinetic simulations of magnetic reconnection are presented to investigate
plasma heating for strongly magnetized, weakly collisional plasmas. For a low
plasma beta case, parallel and perpendicular phase mixing strongly enhance
energy dissipation yielding electron heating. Heating occurs for a long time
period after a dynamical process of magnetic reconnection ended. For a higher
beta case, the ratio of ion to electron dissipation rate increases, suggesting
that ion heating (via phase-mixing) may become an important dissipation channel
in high beta plasmas.
