As the field of ecological restoration grows, novel methods to improve the effectiveness of restoration projects are being advanced and tested. Here, measured plant functional traits are used to select a native planting palette for the restoration of riparian habitat at Strawberry Creek, a heavily invaded urban ecosystem in Berkeley, CA. I partnered with an active restoration program and together we focused on methods to prevent re-invasion by a dominant non-native understory species and reduce nitrogen pollution of the riparian ecosystem. uptake study revealed a marginally significant (0.05

Phosphatase genes have been shown to be involved in male meiosis in the nematode worm, Caenorhabditis elegans, and are expressed in the testis in the fruit fly, Drosophila melanogaster. However, the evolution of this multi-gene family among nematodes and flies had not previously been investigated. We conducted a phylogenetic analysis of all genes in the phosphatase gene family across nematodes and flies using sequences from a 6-way alignment of nematode worms and a 15- way alignment of insects, including 12 Drosophila species. We found that: 1) multiple alignments contain spurious alignments that should be filtered for quality control; 2) several gene sequences with incomplete open reading frames are highly conserved, so may actually be functional genes; and, 3) the phosphatase gene family appears to have expanded independently in the common ancestor of nematodes, and again in the common ancestor of flies (but not all insects).
