    • Welcome to the Atta world: A framework for understanding the effects of leaf‐cutter ants on ecosystem functions 

      Swanson, Amanda C.; Schwendenmann, Luitgard; Allen, Michael F.; Aronson, Emma L.; Artavia León, Allan; Dierick, Diego; Fernandez Bou, Angel Santiago; Harmon, Thomas C.; Murillo Cruz, Catalina; Oberbauer, Steven F.; Pinto Tomás, Adrián A.; Rundel, Philip W.; Zelikova, Tamara Jane (2019)
      1. Leaf‐cutter ants are a prominent feature in Neotropical ecosystems, but a comprehensive assessment of their effects on ecosystem functions is lacking. We reviewed the literature and used our own recent findings to ...
    • What lies behind the curtain: Cryptic diversity in helminth parasites of human and veterinary importance 

      Cháves González, Luis Enrique; Morales Calvo, Fernando Arturo; Mora Rodríguez, Javier Francisco; Solano Barquero, Alberto Alonso; Verocai, Guilherme G.; Rojas Araya, Alicia (2022)
      Parasite cryptic species are morphologically indistinguishable but genetically distinct organisms, leading to taxa with unclear species boundaries. Speciation mechanisms such as cospeciation, host colonization, taxon ...

    • Why myotoxin-containing snake venoms possess powerful nucleotidases? 

      Caccin, Paola; Pellegatti, Patrizia; Fernández Ulate, Julián; Vono, Maria; Cintra Francischinelli, Mariana; Lomonte, Bruno; Gutiérrez, José María; Di Virgilio, Francesco; Montecucco, Cesare (2013-01-25)
      The venom of the snake Bothrops asper causes muscle necrosis, pain and inflammation. This venom contains myotoxins which cause an increase in intracellular Ca2+ concentration and release of K+ and ATP from myotubes. ATP ...
    • Wound exudate as a proteomic window to reveal different mechanisms of tissue damage by snake venom toxins 

      Escalante Muñoz, Teresa; Rucavado Romero, Alexandra; Pinto, Antonio F. M.; Terra, Renata M. S.; Gutiérrez, José María; Fox, Jay W. (2009)
      In light of the complexity of wound tissue, proteomic analysis may not clearly reveal the nature of the wound or the processes involved in healing. However, exudate associated with wounds may provide a “window” on cellular ...
    • Zika Virus (ZIKV): A New Emerging Pathogen Transmitted by Aedes Mosquitoes (Diptera: Culicidae) in the Latin American Subcontinent

      Aedes aegypti and Aedes albopictus (Diptera: Culicidae) are two species of synanthropic mosquitoes that are common in outdoor and indoor domiciliary environments in tropical countries. Their vectorial competence and ...
    • Zoonotic Agents in Feral Pigeons (Columba livia) from Costa Rica: Possible Improvements to Diminish Contagion Risks 

      Torres Mejía, Ana María; Rodríguez Sánchez, César; Duarte Martínez, Francisco; Jiménez Soto, Mauricio; Esperón Fajardo, Fernando; Blanco Peña, Kinndle (2018-01)
      Most studies on zoonotic agents in pigeons have been conducted in the Palearctic region, but the scarcity of data is notorious in the Neotropical region, where these birds can breed all year around and are in close contact ...
    • Zoonotic species of the genus arcobacter in poultry from different regions of Costa Rica
