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...
This paper describes the results of a preliminary project conducted by team DePaul University undergraduate students and staff from Gary Comer Youth Center located on Chicago's South Side. The assessed soil quality 116 samples collected among four abandoned residential lots adjacent to Center. Soil data will be used in follow-up study determine suitability each lot for green infrastructure implementation. Green may useful approach providing ecosystem services mitigating food deserts...
This study investigates small-scale variability in ecosystem services and disservices that is important for sustainable planning urban areas (including suburbs surrounding the core). We quantified valued natural capital (tree soil carbon stocks) (annual tree sequestration pollutant uptake, stormwater runoff reduction) (greenhouse gas emissions soluble reactive phosphorus) within a 30-hectare heterogeneous green space included approximately 13% wetland, prairie, 16% forest, 55% subdivision....
Abstract: During 5 y, we monitored reproductive activity and seed production of Carapa guianensis in two forest types to test the hypothesis that is influenced by multiple factors across scales (regional climatic cues, local habitat heterogeneity individual tree attributes). Variability was moderate at population (CV p = 1.25) level (xCV i 1.24). A mixed model with a Poisson regression revealed explained variables all scales. Total significantly higher occasionally inundated forests....
Various factors affect spatial genetic structure in plant populations, including adult density and primary secondary seed dispersal mechanisms. We evaluated pollen distances of Carapa guianensis Aublet. (Meliaceae) occasionally inundated terra firme forest environments that differed tree densities agents. used parentage analysis to obtain contemporary gene flow estimates assessed the adults juveniles. Despite higher (diameter at breast height ; 25 cm) aggregation forest, average distance was...
Abstract We examined the effects of atmospheric vapor pressure deficit (VPD) and soil moisture stress (SMS) on leaf‐ stand‐level CO 2 exchange in model 3‐year‐old coppiced cottonwood ( Populus deltoides Bartr.) plantations using large‐scale, controlled environments Biosphere Laboratory. A short‐term experiment was imposed top continuing, long‐term treatments (43 120 Pa), at end growing season. For experiment, were exposed for 6–14 days to low high VPD (0.6 2.5 kPa) volumetric contents...
Abstract We used both stated preference and revealed data to estimate willingness pay (WTP) for shade‐grown coffee as compared with conventionally grown coffee. Stated was collected using contingent valuation studies. Revealed came from an experiment where all survey participants received a personally identifiable voucher redeemable free bakery item when the holder purchased estimates of mean median WTP price premium similar data. logit model evaluate effect explanatory variables (measures...
Cottonwood (Populus deltoides Bartr. ex Marsh.) trees grown for 9 months in elevated carbon dioxide concentration ([CO2]) showed significant increases height, leaf area and basal diameter relative to a near-ambient [CO2] control treatment. Sample the CO2 treatments were subjected high low atmospheric vapor pressure deficits (VPD) over 5-week period at both soil water contents (SWC). During these periods, transpiration rates canopy levels calculated based on sap flow measurements...
This work augments research on masting for the economically important tropical tree Carapa guianensis Aublet, specifically whether determinants of mast years vary regionally, spatially, and due to longer term ENSO climate patterns. Longer measurements (an 11-year period in Acre Roraima; 4 8 months Amapá) from three regions Brazilian Amazon allowed analysis cues were regionally consistent this species. We used generalized linear mixed models, determine which factors significant predicting...
Phosphorus (P) release to surface and groundwater often occurs in wetlands that were restored on former agricultural fields. We identified pore water, shallow groundwater, plant biomass decomposition as sources of soluble reactive (SRP) total phosphorus (TP) export the Chicago River between 1998 2014 from Prairie Wolf Slough Wetland Demonstration Project (PWS), a wetland farmed field suburban Chicago, Illinois. estimated relative annual contributions SRP these yearly discharge river...
Background and study species: The endangered oak Quercus brandegeei Goldman, endemic to Baja California Sur, Mexico, is threatened because of its relictual distribution restricted ephemeral riverbeds, declining populations, a lack seedling regeneration. Although there evidence viable acorn production, no seedlings or saplings have been found across the range occurrence for this species. Hypothesis: We tested spatial aggregation factors determining hypothesizing that Q. trees would be less...
For students of environmental science and studies, as well in sustainability programs, critical thinking about the economy–environment interdependence is a key learning objective foundational part undergraduate curriculum. There are many courses that could provide initial exposure to economic theory. However, not all adept at providing this combination thinking, relevance important global issues, interdependence. This article looks neoclassical economics, ecological economics uses literature...
