Zooplankton Vertical Habitat Shifts in Relation to Water Column Optical Properties
On the CCE Process Cruises in the California Current System, we used a Lagrangian sampling design to identify and track a series of discrete water parcels and entrained plankton communities through time.
Luquillo Long-Term Ecological Research Program
Tropical environments are changing fast due to deforestation and regrowth, urbanization, climate change, and other forces. The consequences are immense for the whole array of ecosystem services people require. The Luquillo Long-Term Ecological Research Program (LUQ) is tackling these issues in Puerto Rico. LUQ began in 1988 and focused on natural disturbances (hurricanes, landslides, droughts, floods) and ecosystem response. That work revealed patterns of resistance and resilience to cycles of natural disturbance.
Using EcoTrends to synthesize animal data from the LTER Network
A working group funded by the LNO examined the animal data in the EcoTrends database with the following objectives:
• To provide strategic insight into the products that might arise from use of extant animal-based data in the EcoTrends archive;
• To identify lacunae in data that compromise the development of new insights or understanding;
• To identify shortcomings in metadata that compromise development of new insights or understanding;
Effects of plague and precipitation on burrowing owl diet and breeding success
Burrowing owls (Athene cunicularia) on the Pawnee National Grassland in Colorado nest on black-tailed prairie dog (Cynomys ludovicianus) towns where periodic extinctions from plague (Yersinia pestis) have been studied since 1981. Plague, a non-native pathogen, is typically lethal for prairie dogs and leads to loss of owl nest sites and other habitat changes that may affect owl productivity.
