Abstract Functional traits can determine pairwise species interactions, such as those between plants and pollinators. However, the effects of biogeography evolutionary history on trait‐matching trait‐mediated resource specialization remain poorly understood. We compiled a database 93 mutualistic hummingbird–plant networks (including 181 hummingbird 1,256 plant species), complemented by morphological measures bill floral corolla length. divided hummingbirds into their principal clades used...
Abstract Functional traits determine interactions between plants and pollinators, to increase pollination efficiency, many have evolved attract specific pollinator groups. However, biogeographical setting may influence trait evolution biotic interactions. For instance, pollinated by hummingbirds often ornithophilous traits, that is, flowers with elongated corollas, dilute nectar red colours, but—due colonization history, depauperate biotas unstable environmental conditions—it might be...
Abstract: Plant–animal mutualistic interactions through ecological network systems and the environmental conditions in which they occur, allow us to understand patterns of species composition structure dynamics communities. We evaluated whether flower morphologies with different pollination syndromes (ornithophilous non-ornithophilous) are used by hummingbirds these characteristics affect (core-peripheral species) hummingbird networks. Observations were made flowering patches, where...
RESUMEN ∙ La diversidad taxonómica y funcional de las comunidades aves está determinada por la distribución espacio‐temporal densidad poblaciones especies que integran. puede variar según el gradiente elevación, en general al aumentar elevación se reduce riqueza especies, como es caso algunas colibríes (Trochilidae). En este estudio evaluó distribución, densidad, tres diferentes elevaciones temporadas Reserva Biosfera El Triunfo, Chiapas, México. Establecimos transectos (300 a 2500 m...
An organism's morphological features can determine the type of prey they consume due to adaptive advantages in capturing them, for example, shape and length bill birds. Hummingbirds have been considered specialists nectar consumption. However, documented also be important insectivores ecosystems. In this study, we evaluated arthropod consumption by hummingbirds relation their capture strategies. We theorized that with short-medium bills (9-11 body mass cube root ratio) a higher proportion...
