  • Janzen, Daniel H. (1987-03)
    If there was a crop that grew as well on tropical rainforest soils as do many crops and pastures on tropical dry forest soils, we would not have any rainforest left to argue over. This truth introduces two intense ...
  • Janzen, Daniel H. (1985-12)
    I've grown up on a diet of Darwin, Wallace and their cultural offspring. But I'm faced with the reality of the biology of 100 km2 of lowland dry forest (Santa Rosa National Park) in northwestern Costa Rica. Some of ...

  • Cosier, Mr Peter; Flannery, Tim; Harding, Dr. Ronnie; Karoly, David; Lindenmayer, David; Possingham, Hugh; Purves, Robert; Saunders, Denis; Thom, Bruce; Williams, John; Young, Mike (2009-10-22)
    The focus in climate change policy has centred on reducing greenhouse gas emissions from energy generation, manufacturing and transport, because this is fundamental to any solution to climate change. The science now ...
  • Nelleman, C.; Corcoran, E. (United Nations Environment Programme, 2006)
    Climate change is seriously impacting the world’s marine ecosystems. Massive coral bleaching episodes have impacted the function of the reefs and increased rates of mortality. Coral reefs support over one million plant ...
  • Brooks, Daniel R.; León-Règagnon, Virginia; Pérez-Ponce de León, Gerardo (2000)
    La utilización racional de los recursos aportados por la biodiversidad pueden generar alternativas ecológicas que, a su vez, conlleven ventajas económicas. Es necesario conocer estos recursos (las especies) y su biología ...
  • James R., Spotila; Frank V., Paladino (1990)
  • May-Collado, Laura; Gerrodette, Tim; Calambokidis, John; Rasmussen, Kristen; Sereg, Irena (Revista de Biologia Tropical, 2005-06)
    Nineteen species of cetaceans (families Balaenopteridae, Kogiidae, Physeteridae, Ziphiidae and Delphinidae) occur in the Costa Rican Pacific Exclusive Economic Zone (EEZ). Based on data recorded from the EEZ by the Southwest ...
  • Chapman, Colin (1988-04)
    This paper describes the diet and range use patterns of the three species of primates in Santa Rosa National Park, Costa Rica (Ateles geoffroyi, Alouatta palliata, and Ce bus capucinus) and examines the variation in these ...
  • Janzen, Daniel H. (1981-12)
    In the lowland deciduous and riparian evergreen forests of Guanacaste Province, Costa Rica, the insect seed predators are highly host-specific and display a variety of traits suggesting that the ways they use hosts are ...
  • Vargas, Rita (2000-03-11)
    Periclimenes murcielagensis, new species, a pontoniine shrimp living on black coral colonies, occurs at depths of 25 m at Isla San Pedrito, Archipielago de las Islas Murcielago, Guanacaste, Costa Rica. This new species is ...
  • Kierulff, Maria Cecilia M.; Gatto, Cassiano A. Ferreira; Guidorizzi, Carlos E.; Peres, Carlos A.; Canale, Gustavo R. (PLOS one, 2012)
    Tropical deforestation and forest fragmentation are among the most important biodiversity conservation issues worldwide, yet local extinctions of millions of animal and plant populations stranded in unprotected forest ...
  • Buchs, D. M.; Pilet, S.; Baumgartner, P. O.; Cosca, M.; Flores, K.; Bandini, A. (Goldschmidt Conference Abstracts, 2011)
    The study of volcanism in the ocean is fundamental to better understand the dynamics of the Earth mantle and plate tectonics. However, our understanding of this volcanism is limited by difficulties to access the roots ...
  • Brooks, Daniel R.; McLennan, Deborah A.; León-Règagnon, Virginia; Hoberg, Eric (Revista Mexicana de Biodiversidad, 2006)
    Traditional wisdom, based on assumptions of species-specfic coevolutionary interactions between hosts and parasites, suggests that pathogens with multi-host life cycles are unlikely to move with their definitive hosts ...
  • Janzen, Daniel H. (1983)
    The function of an immature fruit is to add to the photosynthate pool and to protect the developing seed (see Chap. 17, this Vol.). Once ripe, the fruit puts the seed in the appropriate dispersal agent(s) and keeps it ...
