The major objectives were to examine the diets of five demersal fishes and the benthic epifauna (prey field) across contrasting levels of D. vexillum occurrence from 2004 to 2008 in and around northern Closed Area II of Georges Bank (42.0°N, 67.3°W).
These genome-level processes are among the factors that underlie the capacity of Conus species to exploit their taxonomic prey field or adapt to changing biotic conditions (e.g., changes in prey availability, or type of predators or competitors in their environment).
In addition, identification of divergent superfamilies that have only been reported for the generalist feeder C. californicus (Elliger et al. 2011) is consistent with the hypothesis that the high diversity of conopeptides in C. tribblei and C. lenavati may be an adaptation to a wide taxonomic prey field.
Tremendous population movements in the past decade have contributed to the increase in exploitation of the most vulnerable, enabling traffickers an easier preying field.
These new PCR assays were found to be highly sensitive, revealing the consumption of five different prey taxa in field-collected centipedes.
This design allowed us to differentiate direct and indirect effects of the toxin in the host plant from effects attributable to prey quality under field conditions.
This concentration was 10-fold higher than that measured in Bt maize-fed spider mites, an occasional prey species under field conditions that is known to contain high amounts of toxin.
The field was so-named after employees of The Scout Association spotted TV ornithologist Bill Oddie recording a programme about circling birds of prey on the field in 2006.
In accordance, we never observed two spiders competing over prey in the field.
These effects of cannibalism were directly due to an alleviation of food limitation, and not due to any possible genetic correlation between cannibalistic behavior and aggressive foraging behavior for prey, because in Field Experiment 2 females in both treatments had killed a male.
