Seeding rate affects establishment of native perennial legumes in the upper midwestern US

In Minnesota, perennial native legumes (Fabaceae) differed in population and yield response to seeding rates of 14, 67, 135, 275, and 538 pure live seeds (PLS)/m2 (1.3, 6.3, 12.5, 25, and 50 PLS/ft2) when seeded in cultivated seedbeds with little bluestem (Schizachryium scoparium (Michx.) Nash [Poaceae]). Average seeding-year populations were greatest for Illinois bundleflower (Desmanthus illinoensis (Michx.) MacM. ex B.L. Robins. & Fern.) (131 plants/m2); intermediate and similar for false indigo (Amorpha fruticosa L.), wild blue indigo (Baptisia australis (L.) R. Br), and wild senna (Senna hebecarpa (Fern.) H.S. Irwin & Barneby) (average of 72 plants/m2); and least for purple prairie clover (Dalea purpurea Vent) (27 plants/m2). Seeding-year populations of all legumes increased linearly as seeding rate increased. Second-year biomass yield of legumes in mixture with little bluestem ranged from 1.1 Mg/ha(0.5 tons/ac) for purple prairie clover to 5.6 Mg/ha (2.5 tons/ac) for Illinois bundleflower.

Old Norse Nicknames: Origins and Terminology

Nicknames, which occur in all cultures and time periods, play a unique role in highlighting identity. The pool of first names has always been relatively limited, thus most people were identified by their nicknames, especially before surnames became commonplace. The quantity of nicknames in Old Norse literature is large, and recurring nicknames provide a tool for understanding narrative transmission, cultural history, and etymology. Medieval explanations for giving nicknames are suspect, but they provide a glimpse into the possible reasons for so many of them coming down to us. An overview on nickname terminology is provided, as well as literary examples showing the fluidity of medieval terminology in nickname narrative explanations. The overall approach is therefore to explore the ways in which nicknames are described in the literature and how this information aids in understanding medieval Norse society and culture through its naming customs.
