Batcheler: Compensatory Response of Mammal Populations
نویسنده
چکیده
Ecology contributes to management of animal pests in two ways: by defining the precise damage done by the suspect and finding efficient methods of reducing the population to numbers compatible with land use. The latter is the most sought-after service because it concerns development and evaluation of efficient control methods; and herein lies, perhaps, the great bogey of pest control, for this elementary requirement usually amounts to an extremely formidable technical problem. The degree of reduction of numbers, amelioration of the pest's effects, the rate at which survivors increase to reassert their status, and the costs and benefits of control, have all to be taken account of in the evaluation of a technique.

Effect of feed restriction on compensatory growth response of young male goats
Forty eight 8-month-old male goats were divided into three groups. In each group, eight goats were feedrestricted for 45, 60 or 75 days, and eight goats served as the control. Restricted groups were fed with a maintenance ration, and the control goats were fed with a ration supporting 50 g of daily weight gain. At the end of restriction period, the restricted goats were offered the same ration ...
متن کاملSolidago gigantea plants from nonnative ranges compensate more in response to damage than plants from the native range.
Resistance and tolerance are two ways that plants cope with herbivory. Tolerance, the ability of a plant to regrow or reproduce after being consumed, has been studied less than resistance, but this trait varies widely among species and has considerable potential to affect the ecology of plant species. One particular aspect of tolerance, compensatory responses, can evolve rapidly in plant specie...

To follow-up the present study, 40 mature female rats were used. The animals were divided into test,control and sham groups. The rats in the test group were laparotomized and unilateral ovariectomy was done. On the 1st and 2nd met-oestrous after operation, the tissue samples were dissected out and processed for histological study. The intact ovary in the test group underwent a significant (P
متن کاملGlobally attracting attenuant versus resonant cycles in periodic compensatory Leslie models.
We use a periodically forced density-dependent compensatory Leslie model to study the combined effects of environmental fluctuations and age-structure on pioneer populations. In constant environments, the models have globally attracting positive fixed points. However, with the advent of periodic forcing, the models have globally attracting cycles. We derive conditions under which the cycle is a...
