Characterizing herbivore resistance mechanisms: spittlebugs on brachiaria spp. as an example por Parsa, S, Sotelo, G., Cardona, C.

“…The durability of herbivore resistance in an agricultural setting depends to a great extent on the resistance mechanism favored during crop breeding efforts. We demonstrate a no-choice experiment designed to estimate the relative contributions of antibiosis and tolerance to spittlebug resistance in Brachiaria spp. …”

Assessing the factors underlying differences in group performance: Methodological issues and empirical findings from the highlands of central Kenya por Place, Frank, Kariuki, G., Wangila, J., Kristjanson, Patricia M., Makauki, A., Ndubi, J.

“…The empirical analysis focused on the effect of group structural variables (e.g. its size) on performance. We found that choice of performance measure and level at which it is measured (e.g. household, group) matters when it comes to trying to explain the variability in that measure. …”
