abstract parasitic insects face many decisions when foraging for host, some for example frequently have to make decisions with regard to staying in or leaving their current patch. in this study, we investigated how the foraging and oviposition behavior of lysiphlebus fabarum is influenced by (1) a female’s previous experience of encountering aphids host and (2) age of female parasitoids. to tes...

The chronobiological effect on the pharmacokinetics of liposomal encapsulated ampicillin (LEA) was compared at noon (1200) and midnight (2400) after intravenous injection of 50 mg/kg of LEA in rats. The effects of fasting on the circadian rhythms of LEA were also investigated. Serial blood samples were collected for 2 h. Bile and urine were collected during the entire study. Plasma data was ana...

We investigate fluid transport in random velocity fields with unsteady drift. First, we propose to quantify fluid transport between flow regimes of different characteristic motion, by escape probability and mean residence time. We then develop numerical algorithms to solve for escape probability and mean residence time, which are described by backward Fokker-Planck type partial differential equ...

Small bluegill sunfish, Lepomis macrochirus, foraging among patches in the laboratory did not search systematically within a patch; their intercapture intervals did not differ from a model of random prey encounter within a patch. Patch-residence time, number of prey eaten, and giving-up time (time between last prey capture and leaving the patch) were measured for bluegills foraging in two diffe...

Evolutionary adaptation to a new environment depends on theavailability of beneficial alleles. Beneficial alleles may ap-pear as new mutations or may come from standing geneticvariation—alleles already present in the population prior tothe environmental change. Adaptation from standing geneticvariation in sexually-reproducing populations is expected tobe faster than from...

Lewis et al. (14, 15) reported the results of a survey of various derivatives of acridine as pos sible inhibitors of the growth of tumors in mice. Among the series of 70 acridine derivatives which they tested, sixteen 9-aminoacridine compounds were found to inhibit the growth of tumors to the extent that, after 14 days of treatment, they were th@— @ theaveragesizeoftumorsinuntreatedcon trol m...

As part of the PADAPT project, authors compiled invasion biological database alien vascular flora Hungary, which contains nativeness, residence time, introduc- tion mode and status 878 or cryptogenic taxa. In absence adequate evidence, classification some species was only possible into uncertain, transitional cat- egories. The definitions most categories are compatible with several internationa...

background: acanthocephalans are fish parasites of worldwide distribu-tion, penetrate their thorny proboscis into the intestinal wall of host and absorb nutrients. no diagnostic tool is available except postmortem inves-tigations and identification by parasitologists. the aim of present study was to explore and assign taxonomical status to pallisentis species prevalent in food fishes of river g...
