Quantifying coupled spatio-temporal dynamics of phenology and hydrology understanding underlying processes is a fundamental challenge in ecohydrology. While variation factors influencing it have attracted the attention ecologists for long time, influence biodiversity on across landscape largely untested. We measured leaf area index (L) volumetric soil water content (θ) co-located spatial grid to characterize forest forested catchment central Pennsylvania during 2010. used hierarchical...
ABSTRACT Multi‐trophic diversity is often overlooked in land management decisions due to the absence of cost‐ and time‐effective assessment methods. Here, we introduce a new method calculate combined terrain canopy structural complexity metric using LiDAR data, enabling prediction multi‐trophic diversity—a that integrates across trophic levels. We selected 34 forested sites National Ecological Observatory Network test model by observed data on plant presence, beetle pitfall trap, bird count...
Abstract Coastal and deltaic sediment balances are crucial for a region's sustainability. However, such remain difficult to quantify accurately, particularly large regions. We calculate organic mineral mass volume using field measurements from 273 Coastwide Reference Monitoring System sites across the Louisiana Coast between 2006 2015. The rapid relative sea level rise rate (average 13.4 mm/year) is offset by small dry bulk densities observed 0.3 g/cm 3 ) produce 16.2 ± 41.1% deficit 24.1...
Abstract It is a critical time to reflect on the National Ecological Observatory Network (NEON) science date as well envision what research can be done right now with NEON (and other) data and training needed enable diverse user community. became fully operational in May 2019 has pivoted from planning construction operation maintenance. In this overview, history of foundational thinking around are discussed. A framework open described discussion how situated part larger constellation—across...
Stand-replacing fires influence soil nitrogen availability and microbial community composition, which may in turn mediate post-fire successional dynamics nutrient cycling. However, create patchiness at both local landscape scales do not result consistent patterns of ecological dynamics. The objectives this study were to (1) quantify the spatial structure communities forest stands recently affected by stand-replacing fire (2) determine whether variables aid predictions situ net mineralization...
Apple orchard management practices may affect development and phenology of arthropod pests, such as the codling moth (CM), Cydia pomonella (L.) (Lepidoptera: Tortricidae), which is a serious internal fruit-feeding pest apples worldwide. Estimating population dynamics accurately predicting timing CM events (for instance, adult flight, egg-hatch) allows growers to understand control local populations CM. Studies were conducted compare flight in commercial abandoned apple ecosystems using...
The dramatic increase in greenhouse gas (GHG) emissions by humans over the past century and a half has created an urgency for monitoring, reporting, verifying GHG as first step toward mitigating effects of climate change. Fifteen percent global come from agriculture, companies food beverage industry are starting to set goals. We examined reporting practices goals top 100 (as ranked Food Engineering) determined whether their aligned with science keeping warming well below 2°C increase. Using...
The use of models by ecologists and environmental managers, to inform management decision-making, has grown exponentially in the past 50 years. Due logistical, economical, theoretical benefits, model users frequently transfer preexisting new sites where data are scarce. Modelers have made significant progress understanding how improve generalizability during development. However, always imperfect representations systems constrained contextual frameworks used their Thus, need better ways...
Abstract Macrosystem‐scale research is supported by many ecological networks of people, infrastructure, and data. However, no network sufficient to address all macrosystems ecology questions, there much be gained conducting sharing resources across multiple networks. Unfortunately, macrosystem challenging due the diversity expertise skills required, as well issues related data discoverability, veracity, interoperability. The environmental science community could substantially benefit from...
This study investigates the relative influence of biotic and abiotic factors on community dynamics using an integrated approach highlights space genotypic phenotypic traits in plant structure. We examined topography, environment, spatial distance, intra- interspecific interactions distribution performance Boechera stricta (rockcress), a close perennial model Arabidopsis. First, Bayesian kriging, we mapped topography environmental gradients explored naturally occurring rockcress plants two...
Osmia cornifrons (Radoszkowski) (Hymenoptera: Megachilidae) is an effective orchard pollinator. Considering the honey bee population decline in recent years, conservation and propagation of O. as alternative managed pollinator important ensuring adequate pollination tree fruit crops eastern United States. A field study was conducted to determine if nest modifications could reduce mite parasites parasitoid natural enemies that attack cornifrons. Paraffin-coated paper liners (straws) were...
Abstract With the growing availability and accessibility of big data in ecology, we face an urgent need to train next generation scientists science practices tools. One biggest barriers for implementing a data‐driven curriculum undergraduate classrooms is lack training support educators develop their own skills time incorporate these principles into existing courses or new ones. Alongside research goals NEON, providing education are key components building community users equipped utilize...
Logging and forest conversion are occurring at alarming rates in tropical forests. These disturbances alter soil microbial community structure functions. While direct links between changes properties, such as pH well established, the indirect effects of logging on functions poorly understood. We used a space-for-time substitution to investigate diversity across recovery gradient montane forests northern Borneo. surface (top 5 cm) assess physicochemical (next-generation DNA sequencing)...
Abstract With growing public awareness that wetlands are important to society, there intensifying efforts understand the ecological condition of those remain, and develop indicators wetland condition. Indicators based on soils not well developed absent in some current assessment protocols; these could be advantageous, particularly for soils, which complex habitats plants, invertebrates, microbial communities. In this study, we examine whether multivariate soil indicators, correlated with...
Abstract Soil microbial communities play critical roles in various ecosystem processes, but studies at a large spatial and temporal scale have been challenging due to the difficulty finding relevant samples available data sets as well lack of standardization sample collection processing. The National Ecological Observatory Network (NEON) has collecting soil community multiple times per year for 47 terrestrial sites 20 eco‐climatic domains, producing one most extensive standardized sampling...
Researchers commonly use distance variables to: (i) estimate the direct influence of a landmark on an outcome interest, such as neighborhood park home price; or (ii) control for omitted spatial influences that affect predictions key policy variables. While both uses continue, control, to Central Business District (CBD), is now more common. Using given position CBD added multivariate analysis method capture all remaining, effects dependent variable. We show there latent and inherent...
Pollinators contribute to the establishment of perennial native forages, but little is known about effect grazing practices on pollinator abundance and diversity in livestock pasture ecosystems. Grazing reduces floral resources available bees other insects, as a result, may influence their communities. The main objective this study was examine impact sheep non-bee insects established with seed mixes forb/legume/grass warm season grasses. Each divided into two halves (in split-plot design)...
