Litter mass, deposition rate, and chemical composition in bahiagrass pastures managed at different intensities
Date: 2006
Authors: J. C. B. Dubeux, L. E. Sollenberger, S. M. Interrante, J. M. B. Vendramini, and R. L. Stewart
Summary: Authors evaluate the effects of management intensity, defined in terms of N fertilization and stocking rate, on litter mass, deposition rate, and chemical composition in continuously stocked 'Pensacola' bahiagrass (Paspalum notatum) pastures in Flori ...
Keywords: littler mass, decomposition rate, chemical composition, nitrogen fertilization, stocking rate, pensacola bahiagrass, paspalum notatum

Plant responses to defoliation and resource supplementation in the Pryor Mountains
Date: 1999
Authors: J. T. Fahnestock, and J. K. Detling
Summary: Fahnestock and Detling measured the combined effects of selective grass grazing and irrigation in a water limited plant community and fertilization in a nutrient limited plant community on the Pryor Mountain Wild Horse Range. The results of the stud ...

Effects of the timing of multiple grazings by geese on net above-ground primary production of swards of <em>Puccinellia phryganodes</em>
Date: 1991
Authors: D. S. Hik, H. A. Sadul, and R. L. Jefferies
Summary: The effects of multiple grazing sessions (no grazing, early season grazing 1-6 times every 12 days, or early season grazing 2-3 times every 24 days or late-season once every 12 days for three occasions) and fecal input by captive lesser snow geese (& ...

Fates of added nitrogen in freshwater arctic wetlands grazed by snow geese: The role of mosses
Date: 2002
Authors: P. M. Kotanen
Summary: The effects of nitrogen addition from snow goose feces and how the uptake of that nitrogen by mosses affects nitrogen uptake in grasses and sedges were measured in two types of arctic marshes. Mosses form dense mats on the marsh surface preventing le ...
Keywords: chen caerulescens caerulescens, lesser snow goose, nutrient cycling, moss, nitrogen limitation, competition

Defoliation, waterlogging and dung influences allocation patterns of <em>Deschampsia caespitosa</em>
Date: 2003
Authors: E. H. Merrill, and P. J. S. Colberg
Summary: Merrill and Colberg measured the effects of simulated flooding, clipping, and dung addition on tufted hairgrass (<em>Deschampsia caespitosa</em>) in a greenhouse. Root biomass was reduced while above-ground biomass was not affected by fl ...
Keywords: flooding, deschampsia caespitosa, tufted hairgrass, herbivory, nitrogen dynamics, wet meadows
