However, nectar-feeding bats do not exhibit preferences for the sugars present in their diet. We analyzed the role that biochemical and ecological factors could play in shaping the nectar traits of chiropterophilic plants. We studied nectar traits and flower production in 49 plant species. We evaluated the relationship between nectar concentration and sugar composition using phylogenetically independent contrasts and if nectar traits were related to flower production using a Manova. We found that 42 species produced high hexoses nectars, and 7 species produced sucrose rich nectars. Phylogenetically independent contrasts showed that nectar concentration was negatively related to glucose content, positively related to fructose content, and was not related to sucrose content. A negative relationship was found from glucose and fructose contents to sucrose content, and glucose content was negatively related to fructose content. Finally, we did not found any relationship between nectar traits and the plants&#8217; flowering strategies. We conclude that bat physiology and the relative low evolutionary time of the interaction between plants and bats may determine the lack of pattern in the nectar characteristics of chiropterophilic plants.]]></p></abstract>
<abstract abstract-type="short" xml:lang="es"><p><![CDATA[Resumen: La mayoría de los polinizadores prefieren los azúcares presentes en el néctar que consumen, por lo que se ha especulado que estos han moldeado la evolución de los rasgos del néctar. Sin embargo, los murciélagos nectarívoros no muestran preferencias por los azúcares presentes en su dieta. Analizamos el papel que los factores bioquímicos y ecológicos pueden desempeñar en los rasgos de néctar de 32 plantas quirotperofílicas. Se estudiaron las características del néctar y la producción de flores en 49 especies de plantas. Se evaluó la relación entre la concentración del néctar y la composición de azúcares usando contrastes filogenéticamente independientes y si los rasgos del néctar están relacionados con la producción de flores utilizando una Manova. Se encontró que 42 especies producen néctares con altos contenidos de hexosas y 7 especies producen néctares ricos en sacarosa. Los contrastes filogenéticamente independientes mostraron que la concentración de néctar se relaciona negativamente con el contenido de glucosa, positivamente con el de fructosa y no tuvo relación con el contenido de sacarosa. Se encontró una relación negativa del contenido de glucosa y fructosa con el de sacarosa y el contenido de glucosa se relacionó negativamente con el de fructosa. Por último, no encontramos ninguna relación entre los rasgos de néctar y las estrategias de floración. Concluimos que la fisiología de los murciélagos y el poco tiempo evolutivo de la interacción entre las plantas y los murciélagos pueden determinar la falta de patrón en los rasgos del néctar quiropterofílico.]]></p></abstract>
