Unique chemical methodology enables the synthesis of innovative and diverse scaffolds chemotypes allows access to previously unexplored "chemical space." Compound collections based on such new synthetic methods can provide small-molecule probes proteins and/or pathways whose functions are not fully understood. We describe identification, characterization, evolution two probes. In one example, a pathway-based screen for DNA damage checkpoint inhibitors identified compound, MARPIN (ATM ATR...
The coming century is predicted to feature enhanced climatic variability, including increased frequency, intensity, and duration of extreme events. Ecologists are faced with the critical challenge anticipating potentially nonlinear ecosystem responses these changes. High-resolution paleoecological data sets that capture past climate variability provide valuable long-term perspectives on sensitivity ecosystems climate-forced state shifts. We used a suite analyses at Titus Bog in northwestern...
Summary 1. European settlement of eastern North America resulted in dramatic changes to ecosystems, although the dynamics and underlying causes these are not always obvious. For example, land clearance likely exposed soils increased wind erosion, potentially impacting downwind ecosystems indirectly through subsequent enhancement dust deposition. We hypothesized that otherwise undisturbed wetlands were altered this indirect disturbance mechanism, increasing nutrient availability initiating a...
To identify the total duration of hospital stay, costs and outcomes at final discharge for a series Australian patients with hip fracture.The study type was retrospective cohort using episode linkage within between administrative databases. Study population is 2552 veterans war widows primary diagnosis fracture (International Classification Diseases 10th revision, S 72.0-S 72.2) separation dates 1 July 2008 30 June 2009. The unique identifying number Department Veterans' Affairs health...
Understanding the potential for ecosystem transformation and community change in response to climate variability is central anticipating future ecological changes, long-term records provide a primary source of information on these dynamics. We investigated late Holocene history upland forest peatland development at Cranesville Swamp, located along West Virginia–Maryland border USA. Our goal was determine whether establishment triggered by moisture variability, similar recent developmental...
The fundamental assumption underpinning Ecological Sites is that soils, topographic, and climatic variables can be correlated with composition productivity of plant communities sufficient precision to subdivide landscapes by their inherent ecological potential management needs. If are form the basis plans across United States, then methods need standardized refined, especially outside rangeland ecosystems where this conceptual framework was pioneered. We present an approach rapid delineation...
ABSTRACT Monitoring wildlife populations in proximity to industrial activities, including oil and gas operations, is critical mitigating potential risk both animals workers, especially at night. We report on tests of mobile power‐tethered unmanned aerial systems (UASs) equipped with thermal cameras, comparing between these as well more conventional ground‐based camera traps. Our overall objective was develop suggestions for utility UASs by industry monitor populations. focused...
To achieve reclamation certification, oil-and-gas operations in Alberta, Canada are required to monitor the revegetation of idle well pads that no longer support operations. Currently, monitoring is completed by oblique, helicopter-collected photography and on-the-ground field surveys. Both strategies present safety logistical challenges. mitigate these challenges, a remote-sensing project was develop deploy reproducible workflow using high-spatial-resolution satellite imagery progress on...
The identification of unique areas vegetative potential across the Northern Appalachians is complicated by a long land-use history vegetation management. We introduce provisional ecological sites and associated state-and-transition models for region, which can be differentiated latitudinal drivers of: precipitation temperature; local parent material resulting soil differences; landscape position, slope, or aspect. Identification States Phases in provides land managers with quantifiable...
In 1924, Bob Marshall and his Harvard University advisor Richard Fisher developed an integrated historical approach for forest reconstruction to address ecological questions provide insights management. Their utilized complementary methods data: dendrochronology, diverse records (e.g., deeds, town oral histories, census lumber mill records), intensive field mapping sampling of the site including stumps uproot mounds, composition structure. applied this broadly a 61-ha Tsuga canadensis...
Large-scale reforestation efforts require scalable and affordable monitoring technologies to track progress. Boreal forests disturbed by oil gas development provide an opportunity utilize ongoing reclamation assess new with potential utility other regions. In this study, we tested the application of reflectance indices derived from high spatial resolution satellite imagery monitor early-stage reforestation. We installed a randomized nursery experiment in Alberta, Canada wherein total...
