May 9 (Reuters) - Proxy adviser Institutional Shareholder Services on Thursday recommended shareholders of SilverBow Resources vote for the company's board nominees, and withhold support for directors backed by activist investment firm Kimmeridge Energy Management.

Earlier on Thursday, fellow proxy adviser Glass Lewis also recommended SilverBow shareholders vote in the company's board selections.

Kimmeridge, the largest shareholder in SilverBow, is aiming to seat three new independent directors at the oil and gas producer's annual shareholder meeting on May 21, charging the company needs to revamp its governance and improve performance.
