When three is a crowd
Article Abstract:
Plodia interpunctella, an Indian meal moth, confined in a box along with two of its natural enemies, a parasitoid wasp and a granulosis virus, enables the study of community ecology. The role of a pathogen in the population dynamics of the host is limited, but sufficient to refine the intrinsic generation cycles. The parasitoid induces the intrinsic cycles by itself. The cycles occur with a period of 3-4 host-generation lengths when all the three are put in the same box. The existence of many natural enemies with different exploitation patterns decreases the number of species.

Long-term decline in krill stock and increase in salps within the Southern Ocean
Article Abstract:
Antarctic krill and salps are major grazers in the Southern Ocean and krill support commercial fisheries. Krill need the summer phytoplankton blooms of the southwest Atlantic Ocean whereas, salps occupy the extensive lower-productivity regions of the Southern Ocean and tolerate warmer than krill.
