    • Warming and Earlier Spring Increase Western U.S. Forest Wildfire Activity 

      Westerling, Anthony LeRoy; Hidalgo León, Hugo G.; Cayan, Daniel R.; Swetnam, Thomas W. (2006-08-18)
      Western United States forest wildfire activity is widely thought to have increased in recent decades, yet neither the extent of recent changes nor the degree to which climate may be driving regional changes in wildfire has ...
    • Wasp florivory decreases reproductive success in an epiphytic bromeliad 

      Cascante Marín, Alfredo; Wolf, Jan H. D.; Oostermeijer, J. Gerard B. (2009)
      Flower predation or florivory may alter the sexual expression, floral display, and reduce the reproductive success in plants. In this article, we estimated the effect of florivory on the reproductive success of the epiphytic ...
    • What can myxomycetes tell us about floricolous microbial systems? 

      Rojas Alvarado, Carlos Alonso; Valverde González, Randall; Rollins, Adam W.; Murillo Roos, Mariana (2017-02)
      The study described herein was conducted in Costa Rica in an effort to generate baseline data on the association between tropical inflorescences and a group of microorganisms known as myxomycetes. The assemblage structure ...
    • When a little is enough: cocoon web of Kapogea cyrtophoroides (Araneae: Araneidae) induced by Hymenoepimecis heidyae (Ichneumonidae: Pimplinae) 

      Barrantes Montero, Gilbert; Segura Hernández, Laura; Solano Brenes, Diego; Hanson Snortun, Paul (2018)
      The final instar larvae of the koinobiont ectoparasitoids in the Polysphincta group of genera induce their host spiders to construct webs that protect the wasp pupa during its development. It has been hypothesized that ...
    • When genes move farther than offspring: gene flow by male gamete dispersal in the highly philopatric bat species Thyroptera tricolor 

      Buchalski, Michael R.; Chaverri Echandi, Gloriana; Vonhof, Maarten J. (2013-11)
      For species characterized by philopatry of both sexes, mate selection represents an important behaviour for inbreeding avoidance, yet the implications for gene flow are rarely quantified. Here, we present evidence of male ...
    • Why is the electrocaloric effect so small in ferroelectrics? 

      Guzmán Verri, Gian Giacomo; Littlewood, Peter B. (2016-05-19)
      Ferroelectrics are attractive candidate materials for environmentally friendly solid state refrigeration free of greenhouse gases. Their thermal response upon variations of external electric fields is largest in the vicinity ...
    • Widespread local chronic stressors in Caribbean coastal habitats 

      Chollett, Iliana; Collin, Rachel; Bastidas, Carolina; Cróquer, Aldo; Gayle, Peter M. H.; Jordán Dahlgren, Eric; Patterson, Heather M.; Koltes, Karen H.; Oxenford, Hazel A.; Rodríguez Ramírez, Alberto; Weil, Ernesto; Alemu I., Jahson B.; Bone, David; Buchan, Kenneth C.; Creary Ford, Marcia; Escalante Mancera, Edgar; Garzón Ferreira, Jaime; Guzmán Espinal, Héctor M.; Kjerfve, Björn; Klein Salas, Eduardo; McCoy, Croy; Potts, Arthur C.; Ruíz Rentería, Francisco; Smith, Struan R.; Tschirky, John J.; Cortés Núñez, Jorge (2017)
      Coastal ecosystems and the livelihoods they support are threatened by stressors acting at global and local scales. Here we used the data produced by the Caribbean Coastal Marine Productivity program (CARICOMP), the longest, ...
    • Widespread Occurrence of Black-Orange-Black Color Pattern in Hymenoptera 

      Mora Castro, Rebeca; Hanson Snortun, Paul (2019)
      Certain color patterns in insects show convergent evolution reflecting potentially important biological functions, for example, aposematism and mimicry. This phenomenon has been most frequently documented in Lepidoptera and ...
    • XIX Simposio Internacional de Métodos Matemáticos Aplicados a las Ciencias 

      Trejos Zelaya, Javier; Villalobos Arias, Mario Alberto; Barboza Chinchilla, Luis Alberto (2014-05-02)
      El XIX° Simposio Internacional de Métodos Matemáticos Aplicados a las Ciencias (XIX SIMMAC) es el evento de matemática aplicada más importante de América Central. Es organizado por el Centro de Investigación en Matemática ...
    • μ2-Chlorido-chlorido­(μ2-4-{[2-(di­ethyl­amino)­eth­yl]imino}­pent-2-en-2-olato)bis­(tetra­hydro­furan-κO)cobalt(II)lithium 

      Vinocour Pacheco, Felipe Andrés; Soto Navarro, Andrea; Pineda Cedeño, Leslie William (2018)
      The crystal structure of the title compound, [CoLi(C11H21N2O)Cl2(C4H8O)2], has monoclinic symmetry and comprises one heterometallic binuclear complex mol­ecule in the asymmetric unit. The Co2+ cation is bonded to one oxygen ...
