Nitrogen mineralization, nitrification, denitrification, and microbial biomass were evaluated in four representative ecosystems in east-central Minnesota. The study ecosystems included: old field, swamp forest, savanna, ...
Foraging behavior as a determinant of asymmetric competitive interaction between two ant species in a tropical agroecosystem
(Springer-Verlag, 1994-07)
This work is concerned with elucidating competitive interactions between two neotropical ants, Solenopsis geminata and Pheidole radoszkowskii , focusing on their foraging behavior. When released from competition from P. ...
Microclimatic changes and the indirect loss of ant diversity in a tropical agroecosystem
(Springer-Verlag, 1996-11)
Recent changes in the coffee agroecosystem of Costa Rica were used to study the mechanism of biodiversity loss in transforming agroecosystems, focusing on the ground-foraging ant community. Coffee farms are being transformed ...
