Adaptation And Forage Productivity Of Cool-Season Grasses In The Central Usa, Kenneth P. Vogel, Robert B. Mitchell
Adaptation And Forage Productivity Of Cool-Season Grasses In The Central Usa, Kenneth P. Vogel, Robert B. Mitchell
Department of Agronomy and Horticulture: Faculty Publications
Cool-season grass species (18) and cultivars (85) were evaluated for use in seeded grasslands in the tallgrass prairie and shortgrass steppe ecoregions of the central United States at the test locations of Ithaca and Sidney, NE, respectively. Both native and introduced grasses were evaluated in sward trails. Significant differences existed among species and cultivars for all traits evaluated except for in vitro dry matter digestibility (IVDMD) among cultivars within species at Sidney. The grasses that had the best establishment, persistence, and forage yields in the Ithaca trial were introduced wheatgrass (Thinopyrum) and bromegrass (Bromus) species. At …

The identity of an ecological regime is central to modern resilience theory and our understanding of how systems collapse and reorganize following disturbance. However, resilience-based models used in ecosystem management have been criticized for their failure to integrate disturbance outcomes into regime identity. Assessments are needed to understand how well these classifications represent ecosystem responses that occur over management relevant time scales. We tracked post-wildfire forest and grassland dynamics 27 years after wildfire in eastern ponderosa pine savanna. We tested for differences between the assigned identity of a site (forest or grassland) versus classifications based on the site's disturbance history …

With growing populations and pressing environmental problems, future economies will be increasingly plant-based. Now is the time to reimagine plant science as a critical component of fundamental science, agriculture, environmental stewardship, energy, technology and healthcare. This effort requires a conceptual and technological framework to identify and map all cell types, and to comprehensively annotate the localization and organization of molecules at cellular and tissue levels. This framework, called the Plant Cell Atlas (PCA), will be critical for understanding and engineering plant development, physiology and environmental responses. A workshop was convened to discuss the purpose and utility of such an initiative, …
Wildlife Forage Recovery Following Boreal Wildfire, Alexis Jorgensen, Jennifer Baltzer
Wildlife Forage Recovery Following Boreal Wildfire, Alexis Jorgensen, Jennifer Baltzer
Theses and Dissertations (Comprehensive)
Climate change is altering the boreal wildfire regime through increases in the extent and severity of burning and reductions in fire return intervals. These changes can alter the regeneration trajectory of canopy species and ground vegetation, with implications for wildlife habitat. There is some uncertainty about the timelines of when different animal species will use burned areas as their preferred forage taxa recover following fire, and how such recovery is mediated by environmental factors. Here, we aim to address these knowledge gaps through the following questions: 1) What are the main forage types consumed by boreal wildlife and how much …

In Pennsylvania Baptisia australis var. australis is found along only four waterways: the Allegheny River, Youghiogheny River, Clarion River, and Red Bank Creek. Because of its limited distribution and small number of extant populations, the species is considered state-threatened in Pennsylvania. In addition, the riparian prairie habitat that Pennsylvania Baptisia australis var. australis is restricted to is also in decline and considered vulnerable. Because of these conservation concerns, insights into the natural history of the taxon in the state is valuable and will inform conservation efforts. Field surveys and fruit collections along the Allegheny River and herbarium collections were used …

To mitigate the loss of tallgrass prairies through fragmentation and conversion to other land uses, prairie restoration efforts have been undertaken to reclaim areas that have been previously used for agricultural production. Earthworms are a key component of the soil ecology of natural, undisturbed ecosystems. However, limited research exists on earthworm populations in prairie restorations and how earthworm densities may change over time. The objectives of this study were (a) to evaluate earthworm densities in the upper 20 cm of soil over time (i.e., May 2007 and May 2019) in a native prairie and chronosequence of three prairie restorations (i.e., …

Journal of Bioresource Management
The freshwater algae grow in a wide range of aquatic habitats across the globe and are rich in secondary metabolites. The present study was designed to conduct the phytochemical screening, proximate analysis, antioxidant and antibacterial activities of water net (Hydrodictyon reticulatum), an algal weed from Pakistan. The pure and dried algal mass was crushed into a fine powder and four solvent-based extracts were used for phytochemical screening. The results of preliminary qualitative screening indicated the presence of flavonoids, phenols, quinones, steroids, resins, anthraquinones, glycosides, lignin, proteins, saponins, tannins, reducing sugars, alkaloids, terpenoids, fats, and oils, whereas the quantification …

Positive-strand RNA viruses replicate in host cells by forming large viral replication organelles, which harbor numerous membrane-bound viral replicase complexes (VRCs). In spite of its essential role in viral replication, the biogenesis of the VRCs is not fully understood. The authors identified critical roles of cellular membrane-shaping proteins and PI(3)P (phosphatidylinositol 3-phosphate) phosphoinositide, a minor lipid with key functions in endosomal vesicle trafficking and autophagosome biogenesis, in VRC formation for tomato bushy stunt virus (TBSV). The authors show that TBSV co-opts the endosomal SNX-BAR (sorting nexin with Bin/Amphiphysin/Rvs- BAR domain) proteins, which bind to PI(3)P and have membrane-reshaping function during …
