Integrating nitrogen source and application timing into the management of large patch on zoysiagrass
Large patch is the most limiting disease that affects zoysiagrass in the upper transition zone of the United States. Management of this disease requires two to four fungicide applications split between the fall and spring disease periods. Limited research has been conducted to determine the effects …

Evaluation of tall fescue-zoysiagrass polystands and new zoysiagrass genotypes for use in the transition zone
… professional turfgrass managers. In addition, large patch has become the primary pest on zoysiagrass, and improved cultivars with good cold hardiness and large patch resistance are needed in the transition zone. Tall fescue (Schedonorus arundinaceus Schreb), a C3 grass, is used frequently in …

Nesting Success of Grassland Birds in Fragmented and Unfragmented Landscapes of North Central South Dakota
… been linked to habitat loss and fragmentation. A large amount of remaining native prairie is in the form of grazed pastureland; however, few studies have focused on assessing pastureland as habitat. While studies have found that species occurrence, density and breeding success is higher in large, …

The THESAN Project: ionizing escape fractions of reionization-era galaxies
… simulate both small-scale galaxy physics and large-scale reionization throughout a large patch of the universe (𝐿 subscript box = 95.5 cMpc). This allows the formation of numerous massive haloes (𝑀 subscript halo ≳ 10¹⁰ M⊙), which are often statistically underrepresented in previous studies …

Analytical and experimental studies of plant-flow interaction at multiple scales
… At the reach-scale, vegetation is often the largest source of hydraulic resistance. Based on a simple momentum balance, we show that the resistance produced by vegetation depends primarily on the fraction of the channel cross-section blocked by vegetation. For the same blockage, the specific …

Surface Forces between Silica Surfaces in CnTACl Solutions and Surface Free Energy Characterization of Talc
… The measured forces were fitted to a charged-patch model of Miklavic <i>et al</i>. (1994) with rather large patch sizes. It was also found that the decay length decreased linearly with the effective concentration of the CH2/CH3 groups raised to the power of -1/2. This finding is in line with …

The Implications of the Target-Area Hypothesis on the Population Dynamics of the Spotted Spiny Lobster, <i>Panulirus guttatus</i>
… the theory of island biogeography, predicts that larger islands are more effective at intercepting passive immigrants. Most marine invertebrates have meroplanktonic larvae and open population dynamics, so immigration to populations in isolated benthic habitats is primarily by pelagic larval …
