Cormorants must either detect prey visually but only at very short distances, or use a prey-flushing strategy [31] that forces prey to make an escape response.
As a common practice in ecotoxicology and in the non-target assessment of GM plants [10, 15], we designed an experiment in which we exposed A. bipunctata larvae to more realistic concentrations of Bt maize-expressed Cry1Ab using a prey herbivore (the spider mite Tetranychus urticae) as a toxin carrier.
Figs 5 and 6 show two examples from this modelling using a prey item of a size (10 cm total length) commonly taken by cormorants [24], [25].
Had we used a coarse prey classification (e.g., phylum or order level), then more of the stomach samples would have been used, but some diet shifts would not have been identified, for example the transition from Galatheidae to Nephropidae with increasing ling size.
Scat analyses revealed that, in contrast with central sea lions that are using a broad prey spectrum [ 35], trophic niches of fur seals and western sea lions are highly specialised and show little overlap [ 36].
Extant large cats, when killing large prey, use a prolonged suffocating bite to the throat or nose.
For this we use a model with a single prey and predator type, each with an adaptive trait (defense for prey, offense for predators; see Methods for details).
In order to plant green food, one can use a periodic harvesting or stocking prey or predator, instead of using high toxic or high residues pesticide.
They are all hunting spiders, which means they do not use a web to catch their prey. .
The glycerids, also known as bloodworms, are the only annelids known to use a complex venom for overwhelming prey.
And in recent months those opponents recast HERO specifically as "The Bathroom Ordinance," via television ads, narrowly focusing on transgender equality and the right of transgender women to use a public rest room, but preying on public fears and misinformation.
