Abstract

Key Points • Individual biota or taxa sometimes have a disproportionate effect on food web or ecosystem dynamics. • The differences in the architecture of tree species (e.g., Dacryodes excelsa) alter wind disturbance magnitude and effects through the dissipation of wind energy. • Ferns and earthworms can enhance the recolonization rate on bare soils following disturbances through modification of the physical microenviron- ment and nutrient availability. • Freshwater shrimp and earthworms alter nutrient availability in the streams and soils, altering processing rates through effects on detrital processing. • Small vertebrate species such as anolis lizards and tree frogs (Coquis) signifi- cantly alter food web dynamics through direct consumption of herbivorous insects and their cycling of important, limiting nutrients.
