Arthropod and oligochaete assemblages from grasslands of the southern Kenai Peninsula, Alaska

摘要: BACKGROUND By the end of this century, potential climate-biome southern Kenai Peninsula is forecasted to change from transitional boreal forest prairie and grasslands, a scenario that may already be playing out in Caribou Hills region. Here, spruce (Picea × lutzii Little [glauca sitchensis]) forests were heavily thinned by an outbreak bark beetle (Dendroctonus rufipennis (Kirby, 1837)) replaced native but invasive grass species, Calamagrostis canadensis (Michx.) P. Beauv. As part project designed delimit characterize potentially expanding grasslands region, we sought arthropod earthworm communities these grasslands. We also used sampling effort as trial applying high-throughput sequencing metabarcoding methods real-world inventory terrestrial arthropods. NEW INFORMATION documented 131 occurrences 67 species at ten sites, characterizing fauna being dominated Hemiptera (60% total reads) Diptera (38% reads). found single exotic Dendrobaena octaedra (Savigny, 1826), 30% sites one unidentified enchytraeid site. The utility tool for bioassessment assemblages was confirmed.
