The possibility of extending framework dates so that duck-hunting seasons can open earlier and remain open later has been the subject of extensive debate within the waterfowl management community. While potentially desirable from the perspective of hunting opportunity, extended framework dates could increase duck harvests substantially, cause shifts in the distribution of harvest toward more no...

—Worldwide, rice (Oryza sativa) agriculture typically involves seasonal flooding and soil tillage, which provides a variety of microhabitats and potential food for birds. Water management in rice fields creates conditions ranging from saturated mud flats to shallow (<30 cm) water, thereby attracting different guilds of birds. Grain not collected during harvest (i.e. waste rice) is typically the...

This paper presents a number of applied management practices, based on data and research, necessary for dairies in the western United States to produce, store and fed high quality corn silage. These management practices include hybrid selection, growing a quality crop, proper harvest timing, chopping, packing, inoculating and feed out of the stored corn silage.

Using grizzly bears as surrogates for "salmon ecosystem" function, the authors develop a generalizable ecosystem-based management framework that enables decision makers to quantify ecosystem-harvest tradeoffs between wild and human recipients of natural resources like fish.
