Reproductive parameters of captive grey-cheeked mangabeys.

This paper reports reproductive parameters for 9 female grey-cheeked mangabeys kept in a captive colony over a 17-year period. Birth seasonality has shown a consistent trend towards an autumn peak. Oestrous cycles had an average length of 31.2 days: however 'short-cycle' (29.9 days) and 'long-cycle' (37.7 days) groups could be discriminated. Gestation was 175 days, with little variability. Vari...

Pocket gophers kill or slow growth of conifer seedlings. More extensive logging, wildf...

A Novel Strategy for Pocket Gopher Control

Current techniques for the control of pocket gophers use traps, fumigants or toxic baits. Trapping and fumigation are labor intensive and seldom effective in giving more than short-term relief. Toxic baiting usually uses baits that are rapidly degraded and although the resident gopher may be killed the burrow system is frequently reoccupied very rapidly and little long-term control is achieved....
