Potential Biological Control Agents For Nassella Neesiana (Poaceae) Invading Australian Native Grasslands, F. E. Anderson, M. L. Díaz, D. A. Mclaren
IGC Proceedings (1997-2023)
The introduction and proliferation of exotic stipoid grasses over the past 100 years seriously threatens agricultural productivity and the integrity of Australia's indigenous flora and fauna, particularly its grasslands (McLaren et al., 1998). The full effect on biodiversity by the spread of these grasses is unknown but likely to be major (Hocking, 1998). Conventional control techniques have not stopped the invasion adequately, so it is a priority to find control options to achieve an effective management strategy. A biological control project against Nassella trichotoma and N. neesiana was initiated in 1999 in Argentina. We report on the most recent …

Comparing Fungal Communities In Tsuga Heterophylla Seedling Roots Across Nurse Log Decay Stages And The Forest Floor, Ellie Olpin, Reisha Foertsch
Summer Research
Nurse logs are fallen, decaying trees that have been shown to facilitate the survival, establishment, and growth of tree seedlings, therefore making vital contributions to forest regeneration. Plant-fungi interactions may play a role in influencing seedling survival across nurse log decay and the forest floor. We sought to examine how fungal communities in seedling roots change between nurse logs and forest floor as well as across nurse log decay stages. To study this, we collected western hemlock (Tsuga heterophylla) seedlings (5-10 cm) from nurse logs of each decay stage and the forest floor at three field sites on the Olympic …
