    • Above-ground biomass and structure of 260 African tropical forests. 

      Lewis, Simon L; Sonké, Bonaventure; Sunderland, Terry; Begne, Serge K; Lopez-Gonzalez, Gabriela; van der Heijden, Geertje MF; Phillips, Oliver L; ... (63 authors) (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 ...
    • An assessment of skin temperature gradients in a tropical primate using infrared thermography and subcutaneous implants. 

      Thompson, Cynthia L; Scheidel, Caleb; Glander, Kenneth E; Williams, Susan H; Vinyard, Christopher J (J Therm Biol, 2017-01)
      Infrared thermography has become a useful tool to assess surface temperatures of animals for thermoregulatory research. However, surface temperatures are an endpoint along the body's core-shell temperature gradient. Skin ...
    • An estimate of the number of tropical tree species. 

      Slik, JW Ferry; Arroyo-Rodríguez, Víctor; Aiba, Shin-Ichiro; Alvarez-Loayza, Patricia; Alves, Luciana F; Ashton, Peter; Balvanera, Patricia; ... (173 authors) (Proc Natl Acad Sci U S A, 2015-06-16)
      The high species richness of tropical forests has long been recognized, yet there remains substantial uncertainty regarding the actual number of tropical tree species. Using a pantropical tree inventory database from closed ...
    • Deadwood stocks increase with selective logging and large tree frequency in Gabon. 

      Carlson, Ben S; Koerner, Sally E; Medjibe, Vincent P; White, Lee JT; Poulsen, John R (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, ...
    • Elevational ranges of birds on a tropical montane gradient lag behind warming temperatures. 

      Forero-Medina, German; Terborgh, John; Socolar, S Jacob; Pimm, Stuart L (PloS one, 2011-01)
      <h4>Background</h4>Species may respond to a warming climate by moving to higher latitudes or elevations. Shifts in geographic ranges are common responses in temperate regions. For the tropics, latitudinal temperature gradients ...
    • Elevational Ranges of Montane Birds and Deforestation in the Western Andes of Colombia. 

      Ocampo-Peñuela, Natalia; Pimm, Stuart L (PloS one, 2015-01)
      Deforestation causes habitat loss, fragmentation, degradation, and can ultimately cause extinction of the remnant species. Tropical montane birds face these threats with the added natural vulnerability of narrower elevational ...
    • Estimating the Impacts of Local Policy Innovation: The Synthetic Control Method Applied to Tropical Deforestation. 

      Sills, Erin O; Herrera, Diego; Kirkpatrick, A Justin; Brandão, Amintas; Dickson, Rebecca; Hall, Simon; Pattanayak, Subhrendu; ... (11 authors) (PLoS One, 2015)
      Quasi-experimental methods increasingly are used to evaluate the impacts of conservation interventions by generating credible estimates of counterfactual baselines. These methods generally require large samples for statistical ...
    • Experimental manipulation of seed shadows of an Afrotropical tree determines drivers of recruitment. 

      Poulsen, John R; Clark, Connie J; Bolker, Benjamin M (Ecology, 2012-03)
      The loss of animals in tropical forests may alter seed dispersal patterns and reduce seedling recruitment of tree species, but direct experimental evidence is scarce. We manipulated dispersal patterns of Manilkara mabokeensis, ...
    • Long-term thermal sensitivity of Earth's tropical forests. 

      Sullivan, Martin JP; Lewis, Simon L; Affum-Baffoe, Kofi; Castilho, Carolina; Costa, Flávia; Sanchez, Aida Cuni; Ewango, Corneille EN; ... (226 authors) (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 ...
    • Relative growth of the limbs and trunk in sifakas: heterochronic, ecological, and functional considerations. 

      Ravosa, MJ; Meyers, DM; Glander, KE (Am J Phys Anthropol, 1993-12)
      Limb, trunk, and body weight measurements were obtained for growth series of Milne-Edwards's diademed sifaka, Propithecus diadema edwardsi, and the golden-crowned sifaka, Propithecus tattersalli. Similar measures were obtained ...
    • Resistance of African tropical forests to an extreme climate anomaly. 

      Bennett, Amy C; Dargie, Greta C; Cuni-Sanchez, Aida; Tshibamba Mukendi, John; Hubau, Wannes; Mukinzi, Jacques M; Phillips, Oliver L; ... (61 authors) (Proceedings of the National Academy of Sciences of the United States of America, 2021-05)
      The responses of tropical forests to environmental change are critical uncertainties in predicting the future impacts of climate change. The positive phase of the 2015-2016 El Niño Southern Oscillation resulted in unprecedented ...
    • Restoring diversity after cattail expansion: disturbance, resilience, and seasonality in a tropical dry wetland. 

      Osland, Michael J; González, Eugenio; Richardson, Curtis J (Ecol Appl, 2011-04)
      As the human footprint expands, ecologists and resource managers are increasingly challenged to explain and manage abrupt ecosystem transformations (i.e., regime shifts). In this study, we investigated the role of a mechanical ...
    • Targeted habitat restoration can reduce extinction rates in fragmented forests. 

      Newmark, William D; Jenkins, Clinton N; Pimm, Stuart L; McNeally, Phoebe B; Halley, John M (Proceedings of the National Academy of Sciences of the United States of America, 2017-09)
      The Eastern Arc Mountains of Tanzania and the Atlantic Forest of Brazil are two of the most fragmented biodiversity hotspots. Species-area relationships predict that their habitat fragments will experience a substantial ...
