Earthworm Abundances In Endophyte-Infected Tall Fescue Pastures In Northwest Arkansas, Ashley Rashe, Mary C. Savin
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
The ecology of organisms that co-evolve within an ecosystem is likely to be distinct from that involving organisms recently introduced into an area. To better understand the relationship of earthworms with endophyte-infected tall fescue, earthworms in novel and toxic endophyte-infected tall fescue pastures were enumerated and identified as adults or juveniles. We hypothesized that differences in endophyte infection of the fescue would influence earthworm abundances. Earthworms in two toxic and two novel endophyte-infected tall fescue fields in Fayetteville, Ark., were sampled weekly from January through July 2007. Each type of endophyte-infected pasture was established in 1997 and 2003. Sampling was …
