Abstract Wastewater treatment is a major source of anthropogenic nitrous oxide (N 2 O) emissions. However, the current emission estimations rely on uniform factor (EF) proposed by Intergovernmental Panel Climate Change based limited database suffering from large uncertainties and inaccuracies. To address this limitation, study expands 12-fold develops tier-based approach. Our method considers variations across spatial scales, processes monitoring techniques, enabling more-precise...
Gap-based silvicultural systems were developed under the assumption that richness, and diversity of tree species other biota positively respond to variation in size harvest-created canopy gaps. However, varying gap alone often does not meet objectives broader goals address contemporary forest conditions. Recent research highlights need consider site factors history, natural disturbance models, within-gap structure recruitment requirements addition light resources for desired diversity. This...
Significant gaps remain in understanding the response of plant reproduction to environmental change. This is partly because measuring long-lived plants requires direct observation over many years and such datasets have rarely been made publicly available. Here we introduce MASTREE+, a data set that collates reproductive time-series from across globe makes these freely available community. MASTREE+ includes 73,828 georeferenced observations annual (e.g. seed fruit counts) perennial...
Abstract Many managed northern hardwood forests are characterized by low‐diversity tree regeneration. Small harvest gaps, competition from shrub–herb vegetation, and browsing white‐tailed deer ( Odocoileus virginianus ) contribute to this pattern, but we know little about how these factors interact. With a stand‐scale experiment, examined the effects of gap size (0–3234 m 2 ), vegetation (weeded:unweeded), (fenced:unfenced) on seedling growth survival for 18 species. increasing light,...
Over the past decade, considerable emphasis has been placed on development of digital twins for water and wastewater applications. However, physical – if properly designed - offer a higher quality comparison with real system that cannot be achieved by twin. This paper focuses experimental investigations hydrogen sulfide formation in anaerobic sewer lines through biochemical pathways using twin (SPT). The SPT was conceived to independently control sewage residence time, horizontal pipe...
Light is generally regarded as the most important factor affecting tree regeneration in selection managed forests. For decades this paradigm guided forestry Great Lakes region, where small harvest gaps were used to promote shade-tolerant species. However, recent attempts regenerate a more diverse forest community, by varying gap size, have been less successful, bringing predominance of light into question. Here, we investigate influence availability along with local seed production potential...
The U.S. Environmental Protection Agency (U.S. EPA) reports that few wastewater treatment plants with anaerobic digestion beneficially use their biogas beyond process heating. Thus, there must be actual or perceived barriers to broader of produce combined heat and power (CHP).In 2011, the Water Environment Research Foundation (WERF) New York State Energy Development Authority (NYSERDA) conducted a study determine what utilities face in implementing projects.The project team developed an...
Reestablishing appropriate tree species is an important step in converting off‐site monocultures into woodlands. Species conversion often necessary, as exotic rarely function like woodland species. However, when are native, and functionally redundant to species, may be unnecessary. To explore this possibility the southeastern United States, we reviewed literature on trait differences among primary southern pines qualitatively assessed effect of their identity at stand‐levels. In region,...
The southeastern United States was historically characterized by open forests featuring fire-adapted species before land-use change. We compared tree composition and densities of historical surveys (1802 to 1841) contemporary surveys, with the application a similarity metric, in Coastal Plain ecological province Mississippi, USA. detected boundary between pine oak-pine differentiated current forests. In Plain, converted from fire-tolerant longleaf (Pinus palustris) dominance, pines...
Abstract Background Understory flammability is affected by abscised plant tissue. Extensive research has shown how interspecific differences in leaf litter traits affect flammability; however, leaves represent only one component of the layer. Cones and fruit are also common constituents forest floor, yet surprisingly little known about their presence. In this study, we ask cones trait differences, coverage varying species combinations. To address these questions, compared cone morphological...
