AbstractViral Hemorrhagic Septicemia Virus (VHSV) (=Piscine novirhabdovirus) appeared in the Laurentian Great Lakes in 2005, constituting a unique and highly virulent genogroup (IVb), which killed >32 fish species in large 2005 and 2006. Periods of apparent dormancy punctuated smaller outbreaks in 2007, 2008, and 2017. We conducted the first whole genome analysis of IVb, evaluating its evolutionary changes using 46 isolates, in reference to immunogenicity in cell culture, and the genomes of other VHS genogroups (I–IVa) and other Novirhabdoviruses. IVb isolates had 253 genomic nucleotide substitutions (2.3% of the total 11,158 nucleotides), with 85 (16.6%) being non-synonymous. The greatest number of substitutions occurred in the non-coding region (NCDS; 4.3%) followed by the Nv- (3.8%), and M- (2.8%) genes. The M-gene possessed the greatest proportions of amino acid changes (52.9%), followed by the Nv- (50.0%), G- (48.6%), N- (35.7%) and L- (23.1%) genes. Among VHS genogroups, IVa from the northeastern Pacific exhibited the fastest substitution rate (2.01×10-3), followed by Ivb (6.64×10−5), and I/III from Europe (4.09×10−5). A 2016 gizzard shad isolate from Lake Erie was the most divergent IVb isolate (38 NT, 15.0%, 15 AA), yet exhibited reduced virulence with in vitro immunogenicity analyses, as did other 2016 isolates, in comparison to the first IVb isolate (2003). The 2016 isolates exhibited lower impact on innate antiviral responses, suggesting phenotypic effects. Results suggest continued sequence change and lower virulence over the history of IVb, which may facilitate its long-term persistence in fish host populations.

Abstract The National Parks begins in 1851 and ends with Alaska in the 1970s, yet almost entirely erases Indigenous history from the landscape, allowing Native Alaskans, Indigenous Hawaiians, and American Indians no foothold or voice in the modern story of the parks. This is remarkable, considering that all of the parks were established on Indigenous homelands and that Native people and politics continue to be intertwined with the recent history of the parks. The experiences of Ojibwe people in the Great Lakes suggest that the creation of national parks in their homeland was part of a broader colonial history of appropriating Indigenous lands and resources, and extended the damaging policies of the Indian assimilation and allotment era farther into the twentieth century.

The Impact

The Laurentian Great Lakes of North America are home to thousands of native fishes, invertebrates, plants, and other species that not only provide recreational and economic value to the region but also hold an important ecological value. However, there are also 55 nonindigenous species of aquatic plants that may be competing with native species and affecting this value. Here, we use a key regional database—the Great Lakes Aquatic Nonindigenous Species Information System (GLANSIS)—to describe the introduction of nonindigenous aquatic plants in the Great Lakes region and to examine patterns relating to their capacity to compete with native plants species. Specifically, we used an existing catalog of environmental impact assessments to qualitatively evaluate the potential for each nonindigenous plant species to outcompete native plant species for available resources. Despite an invasion record spanning nearly two centuries (1837–2020), a great deal remains unknown about the impact of competition by these species. Nonetheless, our synthesis of existing documentation reveals that many of these nonindigenous species have notable impacts on the native plant communities of the region in general and on species of concern in particular. Furthermore, we provide a thorough summary of the diverse adaptations that may contribute to giving these nonindigenous plants a competitive advantage. Adaptations that have been previously found to aid successful invasions were common in 98% of the nonindigenous aquatic plant species in the database.

Journey To The West

I begin my exploration of ‘Ali Mubarak (1823/4–1893) and the discourses on modernization ‘performed’ in his only attempt at fiction, ‘Alam al-Din (The Sign of Religion, 1882), with a quote from Guy Davenport because it elegantly sums up a key theoretical principle underpinning any discussion of cultural transformation and, more particularly, of modernization. Locating ‘Ali Mubarak and his only fictional work at the juncture of the transformation from the ‘traditional’ to the ‘modern’ in the recent history of Arab culture and of Arabic narrative, I find Davenport's pronouncement tantalizingly appropriate. He not only places the stakes of history and geography in one another, but simultaneously opens up the imagination to the combined forces of time and space that stand behind these two distinct yet related disciplines.
