For both stressors, this stress-induced food intake inhibition was explained by a decrease in meal size and duration, but there was no difference in ingestion speed.
Although no gross differences in water ingestion were observed between diet groups, ingestion was not quantitated.
These results demonstrate how a marine predator that is not dispersal limited alters its foraging strategy throughout the reproductive cycle to maximize energetic gain and how this has led to differences in plastic ingestion.
However, the indirect method alone is accurate for measuring fly feeding during long-term, undisturbed, experimental conditions once assessed by the combined assay for any differences in the ingestion ratio.
Here we examine whether Laysan albatrosses nesting on widely separated islands exploit resources closer to their breeding colonies during the breeding season, how their foraging locations change throughout the reproductive cycle, and whether this leads to differences in plastic ingestion represented in their boluses.
Differences in seed ingestion and burial among soils from mature and successional forests were probably driven by differences in their ability to support earthworm biomass and not by differences in earthworm behaviour as a function of soil type.
Differences in seed ingestion and losses in successional and mature forest soils may have been driven by differences in earthworm abilities to maintain biomass over the course of the experiment.
Furthermore, because tracer methods rely on measuring only the volume of label present in the fly, the results can be influenced by factors other than feeding, and substantial differences in either the ingestion ratio or feeding frequency can be over-looked [18].
These differences in vulnerability to incidental ingestion among arthropod guilds suggest a large potential for shifts in arthropod communities.
Besides the observation of no significant gross changes in control and treated mice examined at necropsy, these authors verified that the oral (20 mM in water) or intraperitoneal (1 ml of 20 mM) administration of farnesol was harmless to mice, since there were no differences in weight or water ingestion between control and farnesol-treated animals.
