Efecto del tamaño corporal y distancia evolutiva en las interacciones agonísticas de colibríes (Trochilidae)

Abstract: Efecto del tamaño corporal y distancia evolutiva en las interacciones agonísticas de colibríes (Trochilidae) Effect of body size and evolutionary distance in the agonistic interactions of hummingbirds (Trochilidae)Resumen Es frecuente que los colibríes de mayor tamaño dominen a especies más pequeñas en contiendas por recursos. Recientemente se ha postulado que en las aves, esta ventaja declina conforme aumenta la distancia evolutiva entre 2 especies interactuantes. En el presente estudio usamos a los colibríes… Show more

“…The energy expenditure of hummingbirds is fueled by energy obtained from the great diversity of flowers they visit. As a result, competition (through territorial behavior) for feeding territories between certain hummingbird species is frequent and plays an important role in determining the structure of their communities (Arizmendi, 2001;Collins, Grey, & Mcnee, 1990;Kuban & Neill, 1980;Lara, 2006;Márquez-Luna, Lara, Corcuera, & Valverde, 2018;Stiles, 1985). However, competition among hummingbird species for these floral resources may lead to some form of niche partitioning (e.g., temporal or spatial), which may, in turn, reduce the intensity of interspecific competition and facilitate coexistence (Arizmendi & Ornelas, 1990;Feinsinger, 1976;Hutto, 1992;Ornelas et al, 2002;Stiles, 1985).…”

“…Overall, resource partitioning among hummingbirds has been explained by different mechanisms related to differences in the use of nectar (Justino, Maruyama, & Oliveira, 2012;Lyon, 1976), which include variation in foraging behavior (Feinsinger & Colwell, 1978;Lara, Lumbreras, & González, 2009;Sandlin, 2000;Stiles, 1985), population movements at the landscape scale following the phenology of their plants (Buzato, Sazima, & Sazima, 2000;Des Granges, 1979;Ortiz-Pulido & Vargas-Licona, 2008), microhabitat differences (Kodric- Brown, Brown, Byers, & Gori, 1984;Ritchie, 2002), spatiotemporal segregation in resource use (Lara, 2006;Lara et al, 2011;Ornelas et al, 2002), and phylogenetic distance between species (Márquez-Luna et al, 2018;Martin & Ghalambor, 2014). Likewise, it has been proposed that interspecific morphological variations in traits, such as body size and bill length and curvature, play an important role in this resource partitioning (Bribiesca, Herrera-Alsina, Ruiz-Sánchez, Sánchez-González, & Schondube, 2019;López-Segoviano, Bribiesca, & Arizmend, 2018;Lyon, 1976;Maglianesi, Bohning-Gaese, & Schleuning, 2015;Rodríguez-Flores & Stiles, 2005;Snow & Snow, 1980;Stiles, 1975).…”

“…Pampa curvipennis (rango = 1.87) que es la especie con mayor masa corporal del ensamble (masa corporal = 9.5±0.03 g, longitud del pico = 27.2±0.02 mm) ocupó un rango ligeramente menor que E. fulgens. En el caso de los colibríes, se ha reportado que las especies de mayor masa corporal tienden a desplazar a las especies más pequeñas del acceso a los recursos florales, es decir, una mayor masa corporal se asocia a un rango mayor de dominancia (Márquez-Luna et al 2018, Bribiesca et al 2019. Este patrón se ha encontrado en otras localidades, donde las especies más grandes dominaron al resto de las especies del ensamble de colibríes.…”

“…Las especies de colibríes con una mayor masa corporal tienden a dominar a especies más pequeñas relegándolas del acceso a los recursos florales (Márquez-Luna et al 2018;Bribiesca et al 2019). Es por esto que las especies más grandes suelen ocupar los rangos más altos dentro de las jerarquías de dominancia.…”
