The growth and development of rice (Oryzae sativa) seedlings was shown to be regulated epigenetically by a fungal endophyte. In contrast to un-inoculated (nonsymbiotic) plants, endophyte colonized (symbiotic) plants preferentially allocated resources into root growth until root hairs were well established. During that time symbiotic roots expanded at five times the rate observed in nonsymbiotic...

The human-biting adult stage of the Rocky Mountain wood tick (Dermacentor andersoni) can cause tick paralysis in humans and domestic animals and is the primary tick vector in the intermountain west of the pathogens causing Colorado tick fever, Rocky Mountain spotted fever, and tularemia. We conducted drag sampling studies in Poudre Canyon and Rocky Mountain National Park of Larimer County, CO, ...

When ancient hearths at open archaeological sites do not yield carbonized annual plant remains or other highquality samples, wood charcoal is commonly used for radiocarbon dating. Sagebrush (Artemisia tridentata Nutt.), a shrub frequently used for fuel across much of the western United States, seems a potentially better candidate for 14C dating than tree wood since the possibility for significa...

The energetic resources in an organism's environment are essential for executing a wide range of life-history functions, including immunity and reproduction. Most energetic budgets, however, are limited, which can lead to trade-offs among competing functions. Increasing reproductive effort tends to decrease immunity in many cases, and increasing total energy via supplemental feedings can elimin...

Abstract Questions Big sagebrush ( Artemisia tridentata ) ecosystems across the western United States have experienced many changes in ecosystem dynamics and vegetation composition over last century due to livestock grazing, non‐native species, changing climate fire regimes. We conducted first systematic investigation of historical change a landscape southwestern States, asking whether or grass...

Arbuscular mycorrhizal fungi (AMF) are drivers of plant communities as they influence competition by increasing plants’ root absorptive surface. As such, AMF could be an important tool for ecological restoration. However, a lack research using in sagebrush steppe implies need more assessments its efficacy. Here, we assessed the ability commercial inoculum to colonize and growth three native Art...
