How the behaviour of parasites and predators promotes population stabilityc equation can introduce either temporary or permanent instability (Maynard-Smith, 1968). In this paper the arguments for parasites will in most cases apply to predators as well. There are, however, two differences that may be important:作者: LIKEN 時間: 2025-3-22 06:10
The kinetics of polyphagy system. Fundamental to elucidating these links and the way in which they may vary is the understanding of the functional response (Solomon, 1949) of individual predators to changes in the density of their various prey. The purpose of this paper is to present one approach to this problem.作者: START 時間: 2025-3-22 11:58

This book derives from the workshop; as such it contributes to the theoretical framework which is increasingly being seen to underlie the body of observation and description of plant and animal communities.作者: BORE 時間: 2025-3-24 17:39 作者: tolerance 時間: 2025-3-24 20:02 作者: 粉筆 時間: 2025-3-25 02:43 作者: 植物學(xué) 時間: 2025-3-25 04:19 作者: 立即 時間: 2025-3-25 11:06
Switching in invertebrate predatorsThis paper deals with certain aspects of the behaviour of invertebrate predators that are potentially important in influencing the structure and stability of their prey populations. It is therefore concerned with a small facet of the broad set of problems embraced by the term ‘ecological stability’.作者: 哀悼 時間: 2025-3-25 15:26 作者: 主動 時間: 2025-3-25 17:55
