West Nile virus is predicted to be more geographically widespread in New York State and Connecticut under future climate changeNARA Subscribed
The effects of climate change on infectious diseases are a topic of considerable interest and discussion. We studied West Nile virus (WNV) in New York (NY) and Connecticut (CT) using a Weather Research and Forecasting (WRF) model climate change scenario, which allows us to examine the effects of climate change and variability on WNV risk at county level. We chose WNV because it is well studied, has caused over 50,000 reported...
Shrubline but not treeline advance matches climate velocity in montane ecosystems of south‐central AlaskaNARA Subscribed
Tall shrubs and trees are advancing into many tundra and wetland ecosystems but at a rate that often falls short of that predicted due to climate change. For forest, tall shrub, and tundra ecosystems in two pristine mountain ranges of Alaska, we apply a Bayesian, error‐propagated calculation of expected elevational rise (climate velocity), observed rise (biotic velocity), and their difference (biotic inertia). We show a sensit...
Isolation of the Hawaiian archipelago produced a highly endemic and unique avifauna. Avian malaria ( Plasmodium relictum ), an introduced mosquito‐borne pathogen, is a primary cause of extinctions and declines of these endemic honeycreepers. Our research assesses how global climate change will affect future malaria risk and native bird populations. We used an epidemiological model to evaluate future bird–mosquito–malaria dynam...

Population dynamics and gene transfer in genetically modified bacteria in a model microcosmNARA Subscribed
The horizontal transfer and effects on host fitness of a neutral gene cassette inserted into three different genomic loci of a plant‐colonizing pseudomonad was assessed in a model ecosystem. The KX reporter cassette (kanamycin resistance, aph , and catechol 2, 3, dioxygenase, xyl E) was introduced on the disarmed transposon mini‐Tn5 into: (I) the chromosome of a spontaneous rifampicin resistant mutant Pseudomonas fluorescens S...
