dc.description.abstractDurante el desarrollo temprano el ambiente puede determinar las condiciones con las cuales los organismos enfrentan las diferentes etapas de su desarrollo. Los anfibios, por su ciclo de vida complejo experimentan múltiples ambientes durante su desarrollo y exhiben respuestas plásticas adaptativas. Esta investigación aborda el efecto de la variación ambiental para el desarrollo larval en tierra y algunas de las respuestas larvales que ocurren previo a la transición al agua. Evaluamos si la terrestrialidad prolongada y la generación de un nuevo nido de espuma larval tiene efectos acumulativos durante el desarrollo a corto plazo en la transición al agua en renacuajos de la especie Leptodactylus fuscus. Para esto evaluamos la producción de espuma larval en diferentes edades (6 y 10d) y número de individuos en el nido (nido completo y mitades), y comparamos la morfología larval de hermanas en las diferentes edades y tratamientos. El volumen total de espuma larval producida aumento con el número de larvas en el nido. Contrario a esto, la velocidad de producción de espuma aumento con la reducción de las larvas en el nido y con la edad de producción, del mismo modo, las larvas que pasaron al agua son más grandes que sus hermanas que permanecieron en tierra produciendo espuma. Estos resultados muestran la importancia del estudio de las respuestas comportamentales y morfológicas de las primeras etapas de vida frente a los cambios en el ambiente de desarrollo.spa
dc.description.abstractDuring early development, the environment can determine the conditions under which organisms face the different stages of their development. Due to their complex life cycle, amphibians experience multiple environments during development and exhibit adaptive plastic responses. This research examines the effect of environmental variation on the development of terrestrial larvae and the responses that occur before they transition to water. We evaluated whether prolonged terrestriality and the generation of a new larval foam nest have cumulative effects on the transition to water during short-term development in tadpoles of the species Leptodactylus fuscus. To do this, we assessed larval foam production at different ages (6 and 10 days) and sisterhood sizes (full nest and halves), and compared the larval morphology of sisters at the various ages and treatments. The total foam volume produced increased with the number of larvae per nest; conversely, the foam production rate rose as the number of larvae decreased and with the age of production. Likewise, the larvae that entered the water are larger than their sisters that remained on land and produced foam. These results highlight the significance of studying the behavioral and morphological responses of early life stages to changes in the developmental environment.eng
