Experimental Tests of the Dependence of Arthropod Diversity on Plant Diversity

Elephants versus butterflies: the ecological role of large herbivores

Indeed, part of perception that large herbivores may be unimportant in rain forests probably stems from the fact that much tropical rain forest research has taken place in the Neotropics, where large h ...
