PREYING PAGE BLANK NOT FILMEr : _
The existing q-Markov COVER realization theory does not take into account the problems of arithmetic errors due to both the quantization of states and coefficients of the reduced order model. All q-Markov COVERs allow some freedom in the choice of parameters. In this paper we exploit this freedom in the existing theory to optimize the models with respect to thes,_ finite wordlength effects. *De...
متن کاملReward for Bdellovibrio bacteriovorus for preying on a polyhydroxyalkanoate producer.
Bdellovibrio bacteriovorus HD100 is an obligate predator that invades and grows within the periplasm of Gram-negative bacteria, including mcl-polyhydroxyalkanoate (PHA) producers such as Pseudomonas putida. We investigated the impact of prey PHA content on the predator fitness and the potential advantages for preying on a PHA producer. Using a new procedure to control P. putida KT2442 cell size...
متن کاملBehavior of Orius insidiosus preying on Aphis gossypii reared on transgenic and conventional cotton varieties
The objective of this study was to evaluate the functional response of Orius insidiosus preying on the third and fourth instars of Aphis gossypii nymphs that were reared on transgenic NuOPAL (Bollgard I Event 531) and conventional Buriti cotton varieties. Fifty O. insidiosus female bugs aged 12–24h were distributed into five different Petri dishes with different densities of A. gossypii (2, 4, ...
متن کاملCollared Forest-Falcon (Micrastur semitorquatus) Preying on Chestnut-mandibled Toucan (Ramphastos swainsonii) in Costa Rica
—Predator-prey interactions occur regularly in nature; however, predation events are difficult to observe in the canopy of tropical rain forests. We describe a successful capture of a Chestnut-mandibled Toucan (Ramphastos swainsonii) by a Collared ForestFalcon (Micrastur semitorquatus) in Carara National Park, Costa Rica. The predator-prey interaction lasted for ,30 min from the moment of the f...
متن کاملToxomerus duplicatus Wiedemann, 1830 (Diptera: Syrphidae) preying on Microtheca spp. (Coleoptera: Chrysomelidae) larvae.
Microtheca spp. (Coleoptera: Chrysomelidae) are insect pests primarily related to Brassicaceae crops. In the State of Rio Grande do Sul (RS), southern Brazil, they are found on forage turnip, Raphanus sativus L. var. oleiferus Metzg., which is commonly grown during fall/winter seasons. This work reports the predation of Microtheca spp. larvae by Toxomerus duplicatus Wiedemann, 1830 (Diptera: Sy...
