Hundreds of field observations of the bears feeding and analyses of grizzly scat reveal that the animals' garbage consumption peaked in the early 1970s, as the number of visitors to the park increased, but declined to practically zero when trashcans were converted to a bear-proof design and municipal dumps in and around the park were shut down, researchers report in the current issue of Ursus.
The HP and HC diets were formulated at the Institute of Animal Nutrition (Freie Universität Berlin, Berlin, Germany) to obtain considerable differences between them, and were analysed according to previously developed standard methods for feed analyses [ 33].
The feed analyses were performed under GLP conditions.
The kinetics of methane production after feeding were analysed on days 20, 160 and 311, in order to represent periods 1, 2 and 3, respectively.
Plasma was collected from these mice at different times after feeding and analysed using the competition ELISA: data are presented as ng ml−1 bOPN, although the assay is probably not measuring intact bOPN.
Using the mosquitoes that laid at least one egg after each blood feeding, we analysed the number of eggs laid at each clutch with a repeated analysis, including exposure to the parasite, larval food and their interaction as factors, and considering age (i.e. clutch) as an ordinal factor.
11 28–31 The present investigation did not decompose CCP to enable analyses of feeding versus non-feeding aspects of childcare, and that is a priority for further analyses.
He added: "It is not my practice to pick up gossip and tittle-tattle which appears in the media and which evidently goes into feeding geopolitical intelligence analyses that are of themselves devoid of strategic content and valid documentation".
To facilitate such analyses, feeding ecology data for a range of vertebrates and invertebrates were collected.
An infant's sucking reflex develops at 34 weeks and this may influence feeding behaviour so analyses were repeated excluding all infants born before 34 weeks gestation but results remained unchanged.
