“…Several other sampling sites were not officially designated as grasslands; nonetheless, they had a substantial grass component. These included grassy balds of the Smoky Mountains (Jenkins, 2007), southern longleaf pinewiregrass communities, dunegrass communities along the Atlantic Coast (Noss, 2013), and northern oak savannas in Wisconsin and Minnesota (Hoffman, 2002).…”

“…distribution, it shows a lag time between parasite and host dispersal. Deeper nodes in the Mesocriconema phylogenetic tree indicate a possible southern U.S. origin of grassland nematode haplotypes (Noss, 2013). Grass hosts that are common to all collection sites and were frequently sampled include big bluestem (Andropogon gerardii Vitman), indiangrass (Sorghastrum nutans (L.) Nash), little bluestem (Schizachyrium scoparium (Michx.)…”

Nematode surveys of North American grasslands conducted from 2010 to 2015 frequently recovered a species of criconematid nematode morphologically resembling Mesocriconema curvatum. These specimens were recovered from remnant native prairies in the central tallgrass ecoregion of North America, and not from surrounding agroecosystems. Historical records indicate that M. curvatum is a cosmopolitan species feeding on a wide range of agronomic and native plants. DNA barcoding indicates North American grasslands contain at least 10 phylogenetically distinct lineages of Mesocriconema that resemble, but are not, M. curvatum. Analysis of the two most common lineages reveals two distinctly different population structures. The variation in population structure suggests unique evolutionary histories associated with their diversification. These two major lineages share a sympatric distribution and their slight morphological differences contrast with a high level of genetic separation. Based on their genetic divergence, fixed diagnostic nucleotides, population structure, species delimitation metrics, and a sympatric distribution, we believe that one of these distinct lineages warrants formal nomenclatural recognition. Herein, we provide formal recognition for Mesocriconema nebraskense n. sp. and discuss its relationship to other Mesocriconema lineages discovered in native North American grasslands.

“…). Although insular ecosystems are a global phenomenon, this review uses the southeastern US as a case study, a region rich in rare plant species that are endemic to insular ecosystems (ie confined to a particular ecosystem and requiring that ecosystem for habitat) (Estill and Cruzan ; Loehle ; Noss ). Concepts presented here are based on a synthesis of more than 300 localized botanical and ecological studies conducted in a variety of ecosystems over several decades (WebPanel 1).…”

Ecological islands: conserving biodiversity hotspots in a changing climate

For decades, botanists have recognized that rare plants are clustered into ecological “islands”: small and isolated habitat patches produced by landscape features such as sinkholes and bedrock outcrops. Insular ecosystems often provide unusually stressful microhabitats for plant growth (due, for example, to their characteristically thin soils, high temperatures, extreme pH, or limited nutrients) to which rare species are specially adapted. Climate‐driven changes to these stressors may undermine the competitive advantage of stress‐adapted species, allowing them to be displaced by competitors, or may overwhelm their coping strategies altogether. Special features of insular ecosystems – such as extreme habitat fragmentation and association with unusual landscape features – could also affect their climate sensitivity and adaptive capacity. To help predict and manage climate‐change impacts, I present a simple conceptual framework based on a synthesis of over 300 site‐level studies. Using this framework, conservation efforts can leverage existing ecological knowledge to anticipate habitat changes and design targeted strategies for conserving rare species.
