The main product of Dr. Oscar Gonzalez dissertation was recently published in the open access journal PeerJ.  This study examined the interactions between birds and flowering plants in elfin forest of the high Andes in Peru.  The study tests the importance of neutral processes and biological constraints in influencing species interactions and network properties.  Biological constraints, such as phenology, emerged as important contributors to these networks. The presence of flower-piercers, which cut holes at the base of flowers, and “rob” nectar, likely explain why morphological constraints were not important, unlike other studies.  To access the paper visit the PeerJ site and click here.
