Response Of Coleoptera Communities To Mammalian Pest Eradication At Maungataurari, New Zealand, Tracy H. Durnell
WWU Honors College Senior Projects
Coleoptera communities are considered effective bioindicators of ecological health and entire invertebrate communities. Mammalian pest-proof fences have been constructed to create two mainland islands at Maungatautari (WO), New Zealand. The objective of this study was to assess the response of Coleoptera communities to pest eradication inside the two pest-free enclosures. Pitfall traps were placed along transect lines at lowland sites inside and outside the enclosures on both the north and south sides of Maungatautari. Invertebrates were collected twice at two week intervals and classified to family. A total of 703 Coleoptera individuals from 21 families were collected. There was no …

The microbial composition of ancient permafrost sediments from the Kolyma lowland of Northeast Eurasia was examined through culture and culture-independent approaches. These sediments have been continuously frozen for 5,000 to 2–3 million years. A total of 265 Bacteria 16S rRNA gene sequences were amplified from the permafrost total-community genomic DNA and screened by amplified ribosomal 16S rRNA restriction analysis. Members of three major lineages were found: gamma-Proteobacteria (mostly Xanthomonadaceae), Actinobacteria, and Firmicutes. We also determined partial 16S rRNA gene sequences of 49 isolates from a collection of 462 aerobes isolated from these sediments. The bacteria included Actinomycetales (Arthrobacter and …
