Neotropical frogs<\/h2>\n

Most of our\u00a0 research focuses on Neotropical frogs that lay terrestrial eggs and have aquatic larvae, and includes work on their natural enemies at multiple life stages. These include species from four lineages that have independently evolved to lay eggs out of water.<\/p>\n

Warkentin has studied red-eyed treefrogs since 1991, in Costa Rica and in Panama. This is the species we know best. We are building an integrative picture of its life, including behavior, development, ecology, evolution, and physiology. Much of our effort is focused on eggs, but we have worked with all life stages. We also do comparative work with other Agalychnis <\/em>species,<\/em> and phyllomedusine treefrogs more broadly.<\/p>\n

Hourglass treefrogs, Dendropsophus ebraccatus<\/em><\/h3>\n

Reproductive mode plasticity in hourglass treefrogs (J.Touchon & KW)<\/p>\n

Justin Touchon, the first Warkentin lab PhD student, added hourglass treefrogs to our study organisms in 2003. Touchon discovered reproductive mode plasticity in D. ebraccatus<\/em> \u2013 this species lays either aquatic or terrestrial eggs, depending on environmental context \u2013 and has gone on to study the evolution of reproductive mode <\/em>in Dendropsophus<\/em> more broadly. The Warkentin lab continues to study ecological developmental biology of early life stages in D. ebraccatus<\/em>, including mechanisms of hatching plasticity (Kristina Cohen’s PhD).<\/p>\n

Glassfrogs, family Centrolenidae<\/h3>\n

\"H.<\/a> H. fleishmanni egg-brooding (J. Delia); E. prosoblepon eggs alone (KW)<\/p>\n

Jesse Delia has worked with glassfrogs since 2003 and brought this clade into our study repertoire when he joined the lab in 2011. In Gamboa, Panama, we work with six species \u2013 Hyalinobatrachium fleishmanni<\/em> and H. colymbiphyllum<\/em> with prolonged paternal care, and Cochranella granulosa, Teratohyla pulverata, T. spinosa <\/i>and Espadarana prosoblepon<\/i> with brief maternal care. Jesse and collaborators have conducted comparative research on many other species in Central and South America. Javier M\u00e9ndez Narv\u00e1ez is studying glassfrog embryo physiology and Mar\u00eda Jos\u00e9 Salazar Nicholls is examining hatching mechanisms.<\/p>\n

Foam-nesting frogs, Leptodactylidae<\/h3>\n

Javier M\u00e9ndez Narv\u00e1ez has worked with leptodactylids since 2012, bringing this work to the Warkentin lab in 2016. In Gamboa, he works with aquatic foam nests of t\u00fangara frogs and terrestrial foam nests of Leptodactylis fragilis.<\/em><\/p>\n
