Priority Areas

 

Even though they're the most abundant and diverse group of animals on the planet, there's still a whole lot we don't know about arthropods. Previous research has shown that arthropods are critical to the stability of terrestrial and freshwater ecosystems because they 1) pollinate almost two-thirds of all flowering plants, 2) decompose leaf litter and wood debris to form humus by, and 3) underpin complex food webs in almost every region they inhabit, linking plants with the larger consumers. Yet, we know little about how land management can influence these arthropod-mediated ecosystem services, especially in eastern grasslands.

For example, does grassland management influence the nutritional quality of arthropods for songbirds? Answering this and other questions can yield useful insights into how to manage land optimally for maintaining ecosystem function, or even inform captive management programs for threatened or endangered birds, like the Loggerhead Shrike.

To address these gaps in our understanding, VWL initiated a new research project in Spring 2018 in collaboration with NZP/SCBI Department of Nutrition Sciences, Smithsonian-Mason School of Conservation, and outside partners. This research will take place on local farms and will quantify how land management influences arthropod diversity and nutritional quality. 

Project Goals:

  • Collect data on arthropod abundance and diversity in native and non-native eastern grasslands
  • Quantify the nutritional quality of arthropods from these habitats for application in ex-situ nutritional management
  • Develop outreach materials highlighting the immense diversity of arthropods in Virginia’s grasslands and their importance in maintaining ecosystem function
  • Expand collaborations between the NZP, SCBI, VWL, SMSC and the local community

By pursuing these research and outreach goals, we aim to better understand how land management influences arthropod diversity, highlight the importance of arthropod communities for supporting ecosystem function, contribute knowledge to inform nutritional management of Smithsonian’s ex-situ bird collection and further engage the local community on Virginia’s native biodiversity.
