Amazon Forest Response to Changes in Rainfall Regime: Results from an Individual-Based Dynamic Vegetation Model
Longo, Marcos (2014-02-25)The Amazon is the largest tropical rainforest in the world, and thus plays a major role on global water, energy, and carbon cycles. However, it is still unknown how the Amazon forest will respond to the ongoing changes ... -
Analytic Steady-state Space Use Patterns and Rapid Computations in Mechanistic Home Range Analysis
Barnett, Alex H.; Moorcroft, Paul (Springer Verlag, 2008)Mechanistic home range models are important tools in modeling animal dynamics in spatially complex environments. We introduce a class of stochastic models for animal movement in a habitat of varying preference. Such models ... -
Confronting Model Predictions of Carbon Fluxes with Measurements of Amazon Forests Subjected to Experimental Drought
Powell, Thomas L; Galbraith, David R.; Christoffersen, Bradley O.; Harper, Anna; Imbuzeiro, Hewlley M. A.; Rowland, Lucy; Almeida, Samuel; Brando, Paulo M.; da Costa, Antonio Carlos Lola; Costa, Marcos Heil; Herrera, Naomi Marcil; Malhi, Yadvinder; Saleska, Scott R.; Sotta, Eleneide; Williams, Mathew; Meir, Patrick; Moorcroft, Paul R (Wiley Blackwell, 2013)Considerable uncertainty surrounds the fate of Amazon rainforests in response to climate change. Here, carbon (C) flux predictions of five terrestrial biosphere models (Community Land Model version 3.5 (CLM3.5), Ecosystem ... -
Determining drought sensitivity of the Amazon forest: does plant hydraulics matter?
Powell, Thomas L. (2015-09-08)Climate change is projected to cause significant shifts in precipitation patterns across the Amazon basin. This dissertation is designed to address key uncertainties surrounding our ability to predict the fate of the Amazon ... -
Ecosystem heterogeneity determines the ecological resilience of the Amazon to climate change
Levine, Naomi; Zhang, Ke; Longo, Marcos; Baccini, Alessandro; Phillips, Oliver L.; Lewis, Simon L.; Alvarez-Dávila, Esteban; Segalin de Andrade, Ana Cristina; Brienen, Roel J. W.; Erwin, Terry L.; Feldpausch, Ted R.; Monteagudo Mendoza, Abel Lorenzo; Nuñez Vargas, Percy; Prieto, Adriana; Silva-Espejo, Javier Eduardo; Malhi, Yadvinder; Moorcroft, Paul R (Proceedings of the National Academy of Sciences, 2015)Understanding how changes in climate will affect terrestrial ecosystems is particularly important in tropical forest regions, which store large amounts of carbon and exert important feedbacks onto regional and global ... -
High sensitivity of peat decomposition to climate change through water-table feedback
Ise, Takeshi; Dunn, Allison L.; Wofsy, Steven; Moorcroft, Paul (Nature Publishing Group, 2008)Historically, northern peatlands have functioned as a carbon sink, sequestering large amounts of soil organic carbon, mainly due to low decomposition in cold, largely waterlogged soils. The water table, an essential ... -
Impacts of climate change and deforestation on hydropower planning in the Brazilian Amazon
Arias, Mauricio E.; Farinosi, Fabio; Lee, Eunjee; Livino, Angela; Briscoe, John; Moorcroft, Paul (Springer Science and Business Media LLC, 2020-03-16)The Amazon Basin is Brazil’s next frontier for hydropower, but alterations to the water cycle from climate change and deforestation could affect river flows fueling electricity generation. This research investigated the ... -
Mechanistic approaches to understanding and predicting mammalian space use: Recent advances, future directions
Moorcroft, Paul R (Oxford University Press (OUP), 2012)The coming of age of global positioning system telemetry, in conjunction with recent theoretical innovations for formulating quantitative descriptions of how different ecological forces and behavioral mechanisms shape ... -
Mechanistic Home Range Models and Resource Selection Analysis: A Reconciliation and Unification
Moorcroft, Paul; Barnett, Alex (Ecological Society of America, 2008)In the three decades since its introduction, resource selection analysis (RSA) has become a widespread method for analyzing spatial patterns of animal relocations obtained from telemetry studies. Recently, mechanistic home ... -
Movement: From individuals to populations

Predicting ecosystem dynamics at regional scales: an evaluation of a terrestrial biosphere model for the forests of northeastern North America
Medvigy, David; Moorcroft, Paul R (The Royal Society, 2011)Terrestrial biosphere models are important tools for diagnosing both the current state of the terrestrial carbon cycle and forecasting terrestrial ecosystem responses to global change. While there are a number of ongoing ... -
Projecting the future of the U.S. carbon sink
Hurtt, G. C.; Pacala, S. W.; Moorcroft, Paul R; Caspersen, J.; Shevliakova, E.; Houghton, R. A.; Moore, B. (Proceedings of the National Academy of Sciences, 2002)Atmospheric and ground-based methods agree on the presence of a carbon sink in the coterminous United States (the United States minus Alaska and Hawaii), and the primary causes for the sink recently have been identified. ... -
Responses of terrestrial ecosystems and carbon budgets to current and future environmental variability
Medvigy, D.; Wofsy, Steven Charles; Munger, J. William; Moorcroft, Paul R (Proceedings of the National Academy of Sciences, 2010)We assess the significance of high-frequency variability of environmental parameters (sunlight, precipitation, temperature) for the structure and function of terrestrial ecosystems under current and future climate. We ... -
Seasonal carbon dynamics and water fluxes in an Amazon rainforest
Kim, Yeonjoo; Knox, Ryan G.; Longo, Marcos; Medvigy, David; Hutyra, Lucy; Pyle, Elizabeth; Wofsy, Steven Charles; Bras, Rafael L.; Moorcroft, Paul R (Wiley-Blackwell, 2012)Satellite-based observations indicate that seasonal patterns in canopy greenness and productivity in the Amazon are negatively correlated with precipitation, with increased greenness occurring during the dry months. Flux ... -
A Spatiotemporal Ripley's K-Function to Analyze Interactions between Spruce Budworm and Fire in British Columbia, Canada
Lynch, Heather J.; Moorcroft, Paul (National Research Council Canada, 2008)In this paper, we extend traditional methods of spatial statistics to study spatiotemporal correlations between two different point processes. After introducing the methodology, we apply this analysis to a particular case ... -
The Structure and Dynamics of Tropical Forests In Relation to Climate Variability
Dong, Shirley Xiaobi (2011-08-22)Although trends and changes in environmental forcing over tropical regions have been recognized, the question remains: how do tropical forests respond to current and future global climate change? Results from long-term ... -
