Intermediate wheatgrass [Thinopyrum intermedium (Host) Barkworth and D.R. Dewey], bred for high grain yield, has become the first perennial in North America is commercialized under tradename Kernza. The expansion of this crop from U.S. Midwest to areas with milder winters would require an understanding its vernalization requirements flowering availability genetic diversity trait. goal research ...

In coastal marshes on James Bay and southern Hudson Bay, Canada, the grass Festuca rubra L. is heavily used for forage by both Snow (Chen caerulescens caerulescens (Linnaeus)) and Canada Geese (Branta canadensis (Linnaeus)). On Akimiski Island, James Bay, this grass occurs in a mosaic of short, heavily grazed patches and tall, lightly grazed patches. We investigated whether short plants are pri...

It is important to develop best management practices for novel tall fescue systems in the southern Great Plains of North America, especially since cool-season perennials are not well known or commonly utilized in this region. This review paper summarizes the research activities in this region of the southern Great Plains for developing new perennial tall fescue systems (establishment, legume-gr...

Cbeatgrass (Bromus tectorum L.) has become the dominant species over large areas of rangeland in the Great Basin region of the western United States. Rapid germination at low temperature may contribute to the competitive success of cheatgrass in areas formerly dominated by native sagebrush and bunchgrass species. The objectives of this study were to determine whether seed priming could be used ...

Members of the tumor necrosis factor (TNF) family play important roles in modulation of immune responses. We describe the identification and cloning of a novel TNF family member that has been designated as TALL-1. TALL-1 is a 285-amino acid type II transmembrane protein. Its carboxy terminus shares approximately 35% sequence identity with the recently identified APRIL and approximately 20-25% w...

Tall fescue (Festuca arundinacea Schreb.) is the most commonly used cultivated grass in the United States to feed beef cattle. Tall fescue is a cool-season perennial grass that many cattle producers ‘can’t live with, but can’t live without’ because of its hardiness and good forage yields, but adverse effects on cattle well-being and yields. The history of this forage and its effects on animal p...

The objective of this research was to determine the relationships between the morphological development and in situ ruminally degradable protein (RDP), ruminally undegradable protein (RUP), and microbial protein of two cool season grasses (intermediate wheatgrass and smooth bromegrass) and two warm season grasses (switchgrass and big bluestem). The initial growth of grass tillers grown near Mea...

This paper claims that the vagueness inherent in gradable adjectives is a reflection of an independently-motivated, underlying measurement mechanism, called the analog magnitude system (AMS). The AMS is a language external system that can be called on to help verify sentences. Differences between positive forms of gradable adjectives like tall (1) and their comparative forms (2), in terms of va...

Habitat structure can be important in determining habitat preference of animals because it is often closely linked to factors that affect survival and reproduction, such as food availability and predation risk. Here we examine the ways in which microhabitat structure and predation risk affect the habitat preference of wild patas monkeys (Erythrocebus patas). Patas monkeys in Kenya are typically...
