A Comparison of Remote Sensing Methods for Estimating Above-Ground Carbon Biomass at a Wetland Restoration Area in the Southeastern Coastal Plain
(2012-04-19)Developing accurate but inexpensive methods for estimating above-ground carbon biomass is an important technical challenge that must be overcome before a carbon offset market can be successfully implemented. Previous studies ... -
Above-ground biomass and structure of 260 African tropical forests.
(Philosophical transactions of the Royal Society of London. Series B, Biological sciences, 2013-01)We report above-ground biomass (AGB), basal area, stem density and wood mass density estimates from 260 sample plots (mean size: 1.2 ha) in intact closed-canopy tropical forests across 12 African countries. Mean AGB is 395.7 ... -
Capacity shortfalls hinder the performance of marine protected areas globally.
(Nature, 2017-03-22)Marine protected areas (MPAs) are increasingly being used globally to conserve marine resources. However, whether many MPAs are being effectively and equitably managed, and how MPA management influences substantive outcomes ... -
Carbon Gain and Allocation in Five Shade Intolerant Pinus Species
(2021-12-08)Pinus virginiana (Virginia pine), Pinus echinata (shortleaf pine), Pinus taeda (loblolly pine), Pinus elliottii (slash pine), and Pinus palustris (longleaf pine) are five of the most dominant shade-intolerant pine species ... -
CARBON STOCKS IN NORTHEASTERN GABON AND POLICY IMPLICATIONS FOR RUBBER TREE CONCESSIONS
(2019-04-24)Agricultural activities such as oil palm and rubber production have the potential to grow the economies and increase employment in tropical nations, but measures must be taken to offset the negative environmental effects ... -
Climate drives the geography of marine consumption by changing predator communities.
(Proceedings of the National Academy of Sciences of the United States of America, 2020-11)The global distribution of primary production and consumption by humans (fisheries) is well-documented, but we have no map linking the central ecological process of consumption within food webs to temperature and other ecological ... -
Contingency in ecosystem but not plant community response to multiple global change factors
(New Phytologist, 2012)Community and ecosystem responses to global environmental change are contingent on the magnitude of change and interacting global change factors. To reveal whether responses are also contingent on the magnitude ... -
Cooking Fuel “Stacking” Implications for Willingness to Switch to Clean Fuels in Peri-urban Kathmandu Valley, Nepal
(2020)Cooking fuel “stacking,” or the use of multiple types of fuels, can be problematic in interventions when households are using both clean and dirty fuels at the same time. Dirty fuels such as firewood contribute to indoor ... -
Deadwood stocks increase with selective logging and large tree frequency in Gabon.
(Glob Chang Biol, 2017-04)Deadwood is a major component of aboveground biomass (AGB) in tropical forests and is important as habitat and for nutrient cycling and carbon storage. With deforestation and degradation taking place throughout the tropics, ... -
Decadal biomass increment in early secondary succession woody ecosystems is increased by CO2 enrichment.
(Nature communications, 2019-02)Increasing atmospheric CO2 stimulates photosynthesis which can increase net primary production (NPP), but at longer timescales may not necessarily increase plant biomass. Here we analyse the four decade-long CO2-enrichment ... -
Differential nutrient limitation of soil microbial biomass and metabolic quotients (qCO2): is there a biological stoichiometry of soil microbes?
(PLoS One, 2013)BACKGROUND: Variation in microbial metabolism poses one of the greatest current uncertainties in models of global carbon cycling, and is particularly poorly understood in soils. Biological Stoichiometry theory describes ... -
Eco-evolutionary feedbacks in community and ecosystem ecology: interactions between the ecological theatre and the evolutionary play.
(Philos Trans R Soc Lond B Biol Sci, 2009-06-12)Interactions between natural selection and environmental change are well recognized and sit at the core of ecology and evolutionary biology. Reciprocal interactions between ecology and evolution, eco-evolutionary feedbacks, ... -
Environmental conditions influence the plant functional diversity effect on potential denitrification.
(PLoS One, 2011-02-02)Global biodiversity loss has prompted research on the relationship between species diversity and ecosystem functioning. Few studies have examined how plant diversity impacts belowground processes; even fewer have examined ... -
Evaluation of 11 terrestrial carbon-nitrogen cycle models against observations from two temperate Free-Air CO2 Enrichment studies.
(The New phytologist, 2014-05)We analysed the responses of 11 ecosystem models to elevated atmospheric [CO2 ] (eCO2 ) at two temperate forest ecosystems (Duke and Oak Ridge National Laboratory (ORNL) Free-Air CO2 Enrichment (FACE) experiments) to test ... -
Experimental evaluation of evolution and coevolution as agents of ecosystem change in Trinidadian streams.
(Philos Trans R Soc Lond B Biol Sci, 2009-06-12)Evolution has been shown to be a critical determinant of ecological processes in some systems, but its importance relative to traditional ecological effects is not well known. In addition, almost nothing is known about the ... -
Experimental evidence that phenotypic divergence in predators drives community divergence in prey.
(Ecology, 2009-02)Studies of adaptive divergence have traditionally focused on the ecological causes of trait diversification, while the ecological consequences of phenotypic divergence remain relatively unexplored. Divergence in predator ... -
Four-decade responses of soil trace elements to an aggrading old-field forest: B, Mn, Zn, Cu, and Fe.
(Ecology, 2008-10)In the ancient and acidic Ultisol soils of the Southern Piedmont, USA, we studied changes in trace element biogeochemistry over four decades, a period during which formerly cultivated cotton fields were planted with pine ... -
Is there foul play in the leaf pocket? The metagenome of floating fern Azolla reveals endophytes that do not fix N2 but may denitrify.
(The New phytologist, 2018-01)Dinitrogen fixation by Nostoc azollae residing in specialized leaf pockets supports prolific growth of the floating fern Azolla filiculoides. To evaluate contributions by further microorganisms, the A. filiculoides microbiome ... -
Long-term thermal sensitivity of Earth's tropical forests.
(Science (New York, N.Y.), 2020-05-21)The sensitivity of tropical forest carbon to climate is a key uncertainty in predicting global climate change. Although short-term drying and warming are known to affect forests, it is unknown if such effects translate into ... -
Low concentrations of silver nanoparticles in biosolids cause adverse ecosystem responses under realistic field scenario.
(PLoS One, 2013)A large fraction of engineered nanomaterials in consumer and commercial products will reach natural ecosystems. To date, research on the biological impacts of environmental nanomaterial exposures has largely focused ...
