Dear All,
I'm working on the impacts of invasive predators that prey
preferentially on large-bodied native species. I am wondering about
impacts on biomass, and whether anyone knows of studies that quantify
the contribution to biomass made by terrestrial invertebrates of
different size-classes?
Clearly, large-bodied invertebrates are less abundant, but how does
this affect their contribution to total biomass in an ecosystem? If
you take the ten largest-bodied terrestrial invertebrate species out
of a system, how will this affect biomass compared to removing the ten
smallest-bodied?
I can't find any papers that graph biomass against size-class in any
natural system, and I'd be really grateful if anyone knows of such work!
Thanks in advance,
James
