They are sometimes known as patch models , but there does not seem to be a common established terminology. All of these modeling approaches (Table 1.1 ) are originally deterministic but have been extended to include stochastic elements.

WebSep 28, 2024 · Kirk highlighted the role weather plays in controlling populations of thrips in field crops. The temperature range during the study was 18–21 °C with a mean of 19.5 °C. The effect of temperature on the dynamics of field S. aurantii populations was not evident. WebAbstract. The aim of this study was to discuss a common concept of population dynamics applicable to both Thrips imaginis (Thysanoptera) and the Pacific stock of the Japanese sardine (Sardinops melanostictus). First, I elucidate the mechanism that produces the false density-dependent effect on population changes of Thrips imaginis, I conducted simple …
