Little difference in the carbon balance of ryegrass/white clover- and plantain-dominated swards under dairy grazingNARA Subscribed
Incorporating plantain into grazed pasture swards is proposed as an approach to reduce nitrate leaching and nitrous oxide emissions. However, consideration must be given to potential emission-swapping, such as a reduction in soil carbon (C), which can contribute to increases in atmospheric CO 2 . We compared the net ecosystem C balance (NECB) of two adjacent newly-sown paddocks (~ 3 ha each) of (i) traditional ryegrass and whi...
Temporal trends and large-scale atmospheric and oceanic forcings of central U.S. snowfall producing weather systems, 1948–2021NARA Subscribed
Snowfall across the central U.S. has undergone significant changes over the last 50–100 years, both with respect to inter-annual totals and event frequencies. While changes are often attributed to warming atmospheric conditions, to-date, there have been limited investigations quantitatively evaluating the potential for changes in snowfall producing weather systems being partially responsible for the observed snowfall trends. H...
The Cost of Antivenom: A Cost Minimization Study using the North American Snakebite RegistryNARA Subscribed
Envenomation is a global health issue, with over 9,000 encounters managed in the United States yearly. The introduction of immunoglobulin fragment antivenom has reduced the risk of hypersensitivity. This study compares treatment costs of crotaline envenomation using the Fab and F(ab’) 2 antivenoms as reported to the North American Snakebite Registry (NASBR), a nationwide surveillance tool. Methods This was a retrospective anal...
Canary in the forest?—Tree mortality and canopy dieback of western redcedar linked to drier and warmer summersNARA Subscribed
Aim Forest dieback is increasing from unfavourable climate conditions. Western redcedar (WRC)—a culturally, ecologically and economically important species—has recently experienced anomalously high mortality rates and partial canopy dieback. We investigated how WRC tree growth and dieback responded to climate variability and drought using tree‐ring methods. Location Pacific Northwest, USA. Taxon Western redcedar ( Thuja plicat...

Bridge to the future: Important lessons from 20 years of ecosystem observations made by the OzFlux networkNARA Subscribed
In 2020, the Australian and New Zealand flux research and monitoring network, OzFlux, celebrated its 20 th anniversary by reflecting on the lessons learned through two decades of ecosystem studies on global change biology. OzFlux is a network not only for ecosystem researchers, but also for those ‘next users’ of the knowledge, information and data that such networks provide. Here, we focus on eight lessons across topics of cli...
Empirical methods for estimating shallow-water bathymetry using passive multispectral satellite imagery are robust and globally applicable, in theory, but they require copious local measurements of water depth for algorithm calibration. Such calibration data have historically been unavailable for most locations, but NASA’s Ice, Cloud, and Land Elevation Satellite-2 (ICESat-2), a satellite-based LiDAR, might hold unique promise...
Identifying dominant environmental predictors of freshwater wetland methane fluxes across diurnal to seasonal time scalesNARA Subscribed
While wetlands are the largest natural source of methane (CH 4 ) to the atmosphere, they represent a large source of uncertainty in the global CH 4 budget due to the complex biogeochemical controls on CH 4 dynamics. Here we present, to our knowledge, the first multi‐site synthesis of how predictors of CH 4 fluxes (FCH4) in freshwater wetlands vary across wetland types at diel, multiday (synoptic), and seasonal time scales. We...
Shared functional traits explain synchronous changes in long‐term count trends of migratory raptorsNARA Subscribed
Aim Assessing long‐term shifts in faunal assemblages is important to understand the consequences of ongoing global environmental change. One approach to assess drivers of assemblage changes is to identify the traits associated with synchronous shifts in count trends among species. Our research identified traits influencing trends in 73 years of count data on migrating raptors recorded in the north‐eastern USA. Location Pennsyl...
