Andy Ramey, Ph.D.
Through my service at the USGS Alaska Science Center, I support the development and application of genetic and genomic tools to advance molecular ecology research pertaining to wildlife health and disease, population genetics, and environmental DNA. Research in the Molecular Ecology Lab promotes informed decisions regarding the conservation of fish and wildlife resources.
I currently serve as the Director of the Molecular Ecology Lab at the USGS Alaska Science Center. The team of scientists working in the Molecular Ecology Lab develops and applies tools to obtain information on the health, distribution, and genomic characteristics of biological natural resources. This includes collecting and interpreting data on the health and disease status of fish and wildlife, the genetics of animal and plant populations, and the distribution of animals and pathogens using environmental DNA. We use this information to help partners and the public to make informed decisions regarding the conservation of fish and wildlife resources.

Assessing the role of seabirds in the ecology of influenza A viruses
Wild waterbirds, specifically waterfowl, gulls, and shorebirds, are recognized as the primordial reservoir of influenza A viruses (IAVs). However, the role of seabirds, an abundant, diverse, and globally distributed group of birds, in the perpetuation and transmission of IAVs is less clear. Here we summarize published and publicly available data for influenza viruses in seabirds, which for the purAuthorsAndrew S. Lang, Camille Lebarbenchon, Andrew M. Ramey, Gregory J. Robertson, Jonas Waldenström, Michelle WilleTemporal, geographic, and host distribution of avian paramyxovirus 1 (Newcastle disease virus)
Newcastle disease is caused by virulent forms of avian paramyxovirus of serotype 1 (APMV-1) and has global economic importance. The disease reached panzootic proportions within two decades after first being identified in 1926 in the United Kingdom and Indonesia and still remains endemic in many countries across the world. Here we review information on the host, temporal, and geographic distributioAuthorsKiril M. Dimitrov, Andrew M. Ramey, Xueting Qiu, Justin Bahl, Claudio L. AfonsoLimited evidence of intercontinental dispersal of avian paramyxovirus serotype 4 by migratory birds
Avian paramyxovirus serotype 4 (APMV-4) is a single stranded RNA virus that has most often been isolated from waterfowl. Limited information has been reported regarding the prevalence, pathogenicity, and genetic diversity of AMPV-4. To assess the intercontinental dispersal of this viral agent, we sequenced the fusion gene of 58 APMV-4 isolates collected in the United States, Japan and the UkraineAuthorsAndrew B.

RameyOptimizing surveillance for South American origin influenza A viruses along the United States Gulf Coast through genomic characterization of isolates from blue-winged teal (Anas discors)
Relative to research focused on intercontinental viral exchange between Eurasia and North America, less attention has been directed towards understanding the redistribution of influenza A viruses (IAVs) by wild birds between North America and South America. In this study, we genomically characterized 45 viruses isolated from blue-winged teal (Anas discors) along the Texas and Louisiana Gulf CoastAuthorsAndrew M.

StallknechtDispersal of H9N2 influenza A viruses between East Asia and North America by wild birds
Samples were collected from wild birds in western Alaska to assess dispersal of influenza A viruses between East Asia and North America. Two isolates shared nearly identical nucleotide identity at eight genomic segments with H9N2 viruses isolated from China and South Korea providing evidence for intercontinental dispersal by migratory birds.AuthorsAndrew M.

HallPrevalence and genetic diversity of haematozoa in South American waterfowl and evidence for intercontinental redistribution of parasites by migratory birds
To understand the role of migratory birds in the movement and transmission of haematozoa within and between continental regions, we examined 804 blood samples collected from eleven endemic species of South American waterfowl in Peru and Argentina for infection by Haemoproteus, Plasmodium, and/or Leucocytozono blood parasites. Infections were detected in 25 individuals of six species for an overallAuthorsMatthew M. Smith, Andrew M. RameyA real-time, quantitative PCR protocol for assessing the relative parasitemia of Leucocytozoon in waterfowl
Microscopic examination of blood smears can be effective at diagnosing and quantifying hematozoa infections. However, this method requires highly trained observers, is time consuming, and may be inaccurate for detection of infections at low levels of parasitemia. To develop a molecular methodology for identifying and quantifying Leucocytozoon parasite infection in wild waterfowl (Anseriformes), weAuthorsMatthew M. Smith, Joel A.

Sampling of sea ducks for influenza A viruses in Alaska during winter provided no evidence for an epidemiologic peak of infection. Isolates were recovered, however, that provide information on viral diversity and dispersal that may not be realized through sampling efforts focused on other avian taxa.AuthorsAndrew M.

Introductions of H7 Influenza A virus (IAV) from wild birds into poultry have been documented worldwide, resulting in varying degrees of morbidity and mortality. H7 IAV infection in domestic poultry has served as a source of human infection and disease. We report the detection of H7N9 subtype IAV in Minnesota turkey farms during 2009 and 2011.

Birds of the order Anseriformes, commonly referred to as waterfowl, are frequently infected by Haemosporidia of the genera Haemoproteus, Plasmodium, and Leucocytozoon via dipteran vectors. We analyzed nucleotide sequences of the Cytochrome b (Cytb) gene from parasites of these genera detected in six species of ducks from Alaska and California, USA to characterize the genetic diversity of HaemosporAuthorsAndrew B.

Although a diverse population of influenza A viruses (IAVs) is maintained among ducks, geese, shorebirds, and gulls, not all of the 16 avian hemagglutinin (HA) subtypes are equally represented (1). The 14th HA subtype, commonly known as the H14 subtype, was historically limited to isolates from the former Soviet Union in the 1980s (2) and was not subsequently detected until 2010, when isolated inAuthorsNeus Latorre-Margalef, Andrew M.

Empirical evidence supports wild birds as playing a role in the interhemispheric exchange of bacteria and viruses; however, data supporting the redistribution of parasites among continents are limited. In this study, the hypothesis that migratory birds contribute to the redistribution of parasites between continents was tested by sampling northern pintails (Anas acuta) at locations throughout theAuthorsAndrew M.
