Crop termination with microwaves: thermo-management of residual plant material and pathogen inoculum in strawberryNARA Subscribed
Crown rot diseases have become increasingly important in strawberry production following the withdrawal of key pesticides due to environmental and human health concerns. The principal causal agents, Macrophomina phaseolina and Fusarium oxysporum f. sp. fragariae , can persist for extended periods in infected crown tissues and residual plant material in soil, serving as inoculum sources for subsequent crops. In some regions, cr...
Quantitative Mineral Resource Assessment of Lithium Pegmatite Deposits in the Southern Appalachian OrogenNARA Subscribed
The first quantitative mineral resource assessment for undiscovered lithium pegmatite deposits in the southern Appalachian region of the United States was conducted. Permissive tracts for lithium pegmatite deposits were delineated by integrating lithological, tectonic, geochemical, geophysical and mineral occurrence data. Lithium pegmatite prospectivity of the tracts was ranked with simplified mappable criteria, including prox...
Wetlands are collectively the largest natural source of methane (CH 4 ), which complicates the climate mitigation potential of wetland restoration. Land‐use change alters wetland soils, vegetation, and hydrology, but the impact of this disturbance legacy on CH 4 fluxes from restored wetlands is uncertain. To better understand CH 4 dynamics across a gradient of human disturbance, we examined 5 yr of continuous CH 4 flux data fr...
Moose ( Alces alces ) are an iconic symbol of contemporary Rocky Mountain ecosystems, and their growing abundance in Colorado and other portions of the Southern Rockies has inspired debate around their regional prehistory prior to their 20th century translocation. The Early Holocene biogeography of moose in North America is poorly characterised, due in part to their life history and logistical obstacles to their archaeozoologi...
Community‐based coastal governance is essential for biodiversity conservation and sustainable livelihoods, yet many communities continue to face significant challenges in establishing and sustaining effective governance systems. We sought to improve understanding of the current status of community‐based coastal governance across five countries in the Southwest Indian Ocean (SWIO) region of Africa. Using the Elinor tool and dat...
The United Kingdom is an important wintering ground for millions of waterbirds. Most U.K. wintering waterbird populations increased between 1970 and the mid‐1990s, but declined thereafter. We examined U.K. population indices in 46 wintering waterbird species in two 25‐year periods, 1970–1994 and 1995–2019, to identify which waterbird groups were vulnerable to declines. We modeled abundance to examine whether spatial patterns i...
Paleoenvironments of the Late Quaternary Tonica thermokarst lake, northeastern Illinois, USA, and an extinct elk‐moose ( Cervalces )NARA Subscribed
The Tonica Depression (TD), a late Quaternary sediment‐filled basin in northeastern Illinois, formed as a thermokarst lake as evidenced by a basal trash layer, its depositional history, and its occurrence on a late‐Pleistocene permafrost landscape. Stratigraphy and radiocarbon ages reveal that a multiproxy paleoenvironmental record extends throughout the late Wisconsin. Burning of organically enriched sediments has abbreviated...
