A densely sampled phylogeny of Carex section Lupulinae (107 specimens) is presented, along with a new cryptic species from the southern United States. This species is locally abundant and genetically and morphologically distinct from other Lupulinae. An identification key is provided and phenological and ecological patterns are discussed.

ABSTRACT Calotropis procera and C. gigantea are emerging as globally invasive plants that can significantly alter ecosystems in areas where they have escaped from attended cultivation. Without effective management, these species can form dense monospecific stands, resulting in severe economic, environmental and social impacts.

Abstract In a time of unprecedented global change, understanding plant community responses to contemporary disturbance regimes is necessary to improve the predictability of restoration outcomes. Although fires in tallgrass prairies historically occurred throughout the growing season, contemporary prescribed fires are often conducted during the dormant ...

An integrated framework to identify and characterize regional‐scale insect dispersal
Abstract Forest pest insects cause major socio‐economic impacts, global losses of millions of dollars, and ecosystem changes. A key challenge for their management is tracing regional dispersal events critical to outbreak dynamics. We developed an integrated tracing framework for pest insects by combining isotope geolocation, ecological data, and ...

The Evolution of Inflorescence Size in Asclepias (Asclepiadaceae) [PDF]
A major feature of floral display in many species is the aggregation of individual flowers into inflorescences. Inflorescences containing different numbers of flowers are likely to be differentially successful as pollen donors and receivers, and thus inflorescence size may influence the fitness of the plant on which an inflorescence is borne.
