Trophic spectrum of Tadarida brasiliensis (Chiroptera: Molossidae) in the southeaster Buenos Aires Province, Argentina

Abstract

Los murciélagos (Orden Chiroptera) se caracterizan por su gran diversidad taxonómica y ecológica, la cual se traduce en numerosos servicios ecosistémicos tales como el control de plagas agrícolas, dispersión de semillas, polinización, entre otros (Kunz et al., 2011;Ghanem & Voigt,

Living with voracious roommates: Factors that explain isotopic niche variation in a mixed colony of insectivorous bats

“…In contrast, T. brasiliensis has a high wing load, which translates to high‐speed flights but with low maneuverability. Besides these morphological differences, several studies have documented distinct selectivity over different species of insects, such as mosquitoes for M. chiloensis and moths for T. brasiliensis (Galaz & Yáñez, 2006 ; Koopman, 1967 ; Mann, 1978 ; Olmedo et al., 2021 ; Silva & Fleck, 1976 ).…”

Diet of Brazilian Free-Tailed Bats (Chiroptera: Molossidae: Tadarida Brasiliensis): A Review

“…compared the diet of bats from underneath the Congress Avenue Bridge,Texas, during 1991Texas, during , 2012Texas, during , and 2013 and found moths to be the dominant insect McWilliams (2005). reports that Lepidopteran occurred in 92.6% of fecal pellets collected from Carlsbad Caverns National Park, New Mexico Olmedo et al (2021). found Lepidoptera in 91% of the fecal samples examined from Estancia and Paititi Nature Reserve, Argentina.…”

“…McWilliams (2005) reports that Lepidopteran occurred in 92.6% of fecal pellets collected from Carlsbad Caverns National Park, New Mexico. Olmedo et al (2021) found Lepidoptera in 91% of the fecal samples examined from Estancia and Paititi Nature Reserve, Argentina. Both Damián (2009) and Hernández (2005) found Lepidoptera to make up the greatest proportion of digested items in La Boca Cave, Mexico.…”

“…Kunz et al (1995) deduce that Coleopterans constituted 26.4% (frequency) of the diet in females from Eckert James River Cave. Olmedo et al (2021) found Coleoptera in 36% of the fecal samples from Estancia and Paititi Nature Reserve. Whitaker and Odegard (2019) showed Coleoptera to be the second most common prey item for bats roosting under the Congress Avenue Bridge in 1991.…”

“…Whitaker and Rodriguez-Duran (1999) also found less than 1% frequency of mosquitoes in their diet analysis of T. brasiliensis antillularum in Puerto Rico. Olmedo et al (2021) found mosquitos to make up ∼12% of the relative frequency of prey in the digestive tract of bats in Estancia and Paititi Nature Reserve. The results of these three studies were based on visual identification of fecal pellets.…”
