    • A novel framework for analyzing conservation impacts: evaluation, theory, and marine protected areas. 

      Mascia, Michael B; Fox, Helen E; Glew, Louise; Ahmadia, Gabby N; Agrawal, Arun; Barnes, Megan; Basurto, Xavier; ... (20 authors) (Ann N Y Acad Sci, 2017-07)
      Environmental conservation initiatives, including marine protected areas (MPAs), have proliferated in recent decades. Designed to conserve marine biodiversity, many MPAs also seek to foster sustainable development. As is ...
    • A typology of time-scale mismatches and behavioral interventions to diagnose and solve conservation problems. 

      Wilson, Robyn S; Hardisty, David J; Epanchin-Niell, Rebecca S; Runge, Michael C; Cottingham, Kathryn L; Urban, Dean L; Maguire, Lynn A; ... (10 authors) (Conserv Biol, 2016-02)
      Ecological systems often operate on time scales significantly longer or shorter than the time scales typical of human decision making, which causes substantial difficulty for conservation and management in socioecological ...
    • 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 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 ...
    • Bird extirpations and community dynamics in an Andean cloud forest over 100 years of land-use change. 

      Palacio, Ruben D; Kattan, Gustavo H; Pimm, Stuart L (Conservation biology : the journal of the Society for Conservation Biology, 2020-06)
      Long-term studies to understand biodiversity changes remain scarce-especially so for tropical mountains. We examined changes from 1911 to 2016 in the bird community of the cloud forest of San Antonio, a mountain ridge in ...
    • Buying into conservation: intrinsic versus instrumental value. 

      Justus, James; Colyvan, Mark; Regan, Helen; Maguire, Lynn (Trends Ecol Evol, 2009-04)
      Many conservation biologists believe the best ethical basis for conserving natural entities is their claimed intrinsic value, not their instrumental value for humans. But there is significant confusion about what intrinsic ...
    • Capacity shortfalls hinder the performance of marine protected areas globally. 

      Gill, David A; Mascia, Michael B; Ahmadia, Gabby N; Glew, Louise; Lester, Sarah E; Barnes, Megan; Craigie, Ian; ... (22 authors) (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 ...
    • China's endemic vertebrates sheltering under the protective umbrella of the giant panda. 

      Li, Binbin V; Pimm, Stuart L (Conservation biology : the journal of the Society for Conservation Biology, 2016-04)
      The giant panda attracts disproportionate conservation resources. How well does this emphasis protect other endemic species? Detailed data on geographical ranges are not available for plants or invertebrates, so we restrict ...
    • Climate change, disease range shifts, and the future of the Africa lion. 

      Carter, Neil H; Bouley, Paola; Moore, Sean; Poulos, Michael; Bouyer, Jérémy; Pimm, Stuart L (Conservation biology : the journal of the Society for Conservation Biology, 2018-10)
    • Costa Rica's payment for environmental services program: intention, implementation, and impact. 

      Sánchez-Azofeifa, G Arturo; Pfaff, Alexander; Robalino, Juan Andres; Boomhower, Judson P (Conserv Biol, 2007-10)
      We evaluated the intention, implementation, and impact of Costa Rica's program of payments for environmental services (PSA), which was established in the late 1990s. Payments are given to private landowners who own land ...
    • Discharge competence and pattern formation in peatlands: a meta-ecosystem model of the Everglades ridge-slough landscape. 

      Heffernan, James B; Watts, Danielle L; Cohen, Matthew J (PLoS One, 2013)
      Regular landscape patterning arises from spatially-dependent feedbacks, and can undergo catastrophic loss in response to changing landscape drivers. The central Everglades (Florida, USA) historically exhibited regular, linear, ...
    • 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 ...
    • Emerging Technologies to Conserve Biodiversity. 

      Pimm, Stuart L; Alibhai, Sky; Bergl, Richard; Dehgan, Alex; Giri, Chandra; Jewell, Zoë; Joppa, Lucas; ... (9 authors) (Trends in ecology & evolution, 2015-11)
      Technologies to identify individual animals, follow their movements, identify and locate animal and plant species, and assess the status of their habitats remotely have become better, faster, and cheaper as threats to the ...
    • 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 ...
    • Estimating the normal background rate of species extinction. 

      De Vos, Jurriaan M; Joppa, Lucas N; Gittleman, John L; Stephens, Patrick R; Pimm, Stuart L (Conservation biology : the journal of the Society for Conservation Biology, 2015-04)
      A key measure of humanity's global impact is by how much it has increased species extinction rates. Familiar statements are that these are 100-1000 times pre-human or background extinction levels. Estimating recent rates ...
    • Evaluating interactions of forest conservation policies on avoided deforestation. 

      Robalino, Juan; Sandoval, Catalina; Barton, David N; Chacon, Adriana; Pfaff, Alexander (PLoS One, 2015)
      We estimate the effects on deforestation that have resulted from policy interactions between parks and payments and between park buffers and payments in Costa Rica between 2000 and 2005. We show that the characteristics ...
    • Genetic evaluation of a proposed introduction: the case of the greater prairie chicken and the extinct heath hen. 

      Palkovacs, EP; Oppenheimer, AJ; Gladyshev, E; Toepfer, JE; Amato, G; Chase, T; Caccone, A (Mol Ecol, 2004-07)
      Population introduction is an important tool for ecosystem restoration. However, before introductions should be conducted, it is important to evaluate the genetic, phenotypic and ecological suitability of possible replacement ...
    • Global protected area impacts. 

      Joppa, Lucas N; Pfaff, Alexander (Proc Biol Sci, 2011-06-07)
      Protected areas (PAs) dominate conservation efforts. They will probably play a role in future climate policies too, as global payments may reward local reductions of loss of natural land cover. We estimate the impact of ...

      Swenson, Jennifer J; Carter, Catherine E; Domec, Jean-Christophe; Delgado, Cesar I (PLoS One, 2011-04-19)
      Many factors such as poverty, ineffective institutions and environmental regulations may prevent developing countries from managing how natural resources are extracted to meet a strong market demand. Extraction for some ...
