to agree with statements such as, "I use coupons on most of my shopping trips," and, "I always look around food aisles in non-grocery stores for a good deal or to see what's there.
Thus, when the zooplankton community is dominated by low-N:P grazers
(such as Daphnia), recycling N:P should be high, but, when grazers
have high body N:P, recycling N:P should be low.
Chlorophyll a increased with nitrogen load, but the amount of chlorophyll removed by grazer
populations in each estuary remained constant.
The use of both natural and experimental data serve an additional objective - that the patterns observed are not an artifact of disturbance produced during experimental manipulations such as addition or removal of grazers
or experimental enrichment.
Gammarus was used in all trials because it was the most abundant grazer
gathered with the algae.
These possibilities notwithstanding, there is compelling evidence that competition for microalgae often is sufficiently intense to strongly influence local densities of grazers
Curiosity inspired Grazer
to launch his now-legendary "curiosity conversations," in which he meets one on one with an impressive array of scientists, actors, politicians and other celebrities.
What he'd like to know more about, he says, is how much benefit the grazers
get from their fungus-fighting saliva.
asks a reporter, suddenly bolting upright, his gold-and-white leather encased iPhone vibrating.
Mammoths were grazers
, so had stronger teeth to grind their food.
In this paper we describe an experiment in which we measured net growth of a common macroalga, Ulva lactuca, in treatments that allowed different numbers of grazers
to access fronds as well as incubation of fronds in estuaries with demonstrably different nutrient supplies.
No doubt he'll be milking undiscerning grazers
in London within weeks.
