Mixed Species Seeding: A Means To Increase Production In Temperate Pastures, Michael P. Schellenberg, Bili Biligetu, Valentin Picasso
Mixed Species Seeding: A Means To Increase Production In Temperate Pastures, Michael P. Schellenberg, Bili Biligetu, Valentin Picasso

Seeding mixed species for forage production has been suggested as a means of increasing productivity and stabilizing yields under a changing climate. Forages have traditionally been sown as monocultures or binary mixtures only, with the emphasis being on species and not necessarily their function or compatibility. While natural plant communities typically may be dominated by a single species, they are comprised of several species and function-al groups.
This paper provides the results of sowing multiple species at semiarid sites within the North American Great Plains and identifies a similar result from a more humid region reported within the literature.

Species-rich swards have received increasing interest due to their focus on ecosystem services, animal welfare and product quality. However, in high-yielding swards the proportion of herbs is often limited and there is little knowledge of their management. Seed mixture composition, cutting frequency, fertilization and grazing/cutting strategies were examined over 4 years in 3 experiments to quantify their effects on herbage yield and botanical composition. Inclusion of herbs in the sward gave similar or higher annual yields but swards established with 100% herbs depended on the presence of a driver species. The effects of management differed between species. Herb content in …
Effectiveness Of Different Agricultural Management Styles As Insect Biological Corridors: A Comparison Of Insect Populations In Fragmented Chocó Cloud Forest, Ecuador, Tara M. Krantz
Independent Study Project (ISP) Collection
Insects are part of the most diverse class of animals on the planet and are essential to various ecological functions such as pollination, nutrient cycling, providing a food source for other taxa, and more. The diversity and ecological services of insects are necessary to the operation of agriculture because of pest control and pollination of crops. However, the diversity of insects is severely reduced due to fragmentation. It is currently not well understood if certain types of agriculture can lessen the impact of fragmentation on natural and crop-based insect communities. In this study, insect populations in four different agricultural management …
