Article
Bat populations are threatened in many regions of the world, partly due to the loss of foraging and commuting habitats in farmland and declines in insect prey populations caused by agricultural intensification. Given that bats play an important role as bioindicators and in suppressing crop pests, it is crucial to mitigate negative impacts that aris...
Article
The bat fauna from the extreme north of Chile is poorly known, principally due to a lack of dedicated surveys. To better assess the diversity of bats there, we conducted acoustic surveys at Arica city and three coastal valleys (Azapa, Lluta and Camarones) in the Arica and Parinacota region, Chile. We obtained 82 acoustic records of the Peale’s free...

The common vampire bat ( Desmodus rotundus ) is a sanguivorous (i.e., blood-eating) bat species distributed in the Americas from northern Mexico southwards to central Chile and Argentina. Desmodus rotundus is one of only three mammal species known to feed exclusively on blood, mainly from domestic mammals, although large wildlife and occasionally h...
Article
Davison’s Mastiff Bat Promops davisoni is a poorly studied species, only present in Ecuador, Peru and more recently in Chile, where its known geographic distribution is supported by very few records from the extreme north of the country. Using ultrasonic recordings, we reported new records of P. davisoni in northern Chile, extending its distributio...
Article
The protozoan Trypanosoma cruzi, the causative agent of Chagas disease, is transmitted by infected feces or consumption of blood-sucking triatomine insects to several mammalian orders including Chiroptera. In Chile, the distribution of several insectivorous and one hematophagous bat species overlaps with those of triatomine vectors, but the T. cruz...

Introduction: The common vampire bat (Desmodus rotundus) is currently one of the most impactful transmissors of rabies throughout Latin America. Despite its importance as a natural reservoir, little is known about the historical distribution of D. rotundus. Detailed occurrence data are necessary for the accurate assessment of the ecology and epidem...
Article
The Atacama Myotis is an endangered and poorly studied bat species, endemic from Peru and Chile. Using mist nets and ultrasonic recordings we release new information on activity patterns and roost use by M. atacamensis in Chile. We also report new records for the species, extending its distribution range to Santiago Metropolitan region. Our results...
Article
Conversion of natural land covers to agriculture is a major cause of the global biodiversity decline. Bats are an important component of biodiversity in agricultural landscapes because they provide pest control services. Although management recommendations towards the enhancement of insectivorous bat populations in agro-ecosystems have previously b...
Article
The top-down suppression of pest insects by their natural enemies, such as insectivorous bats, represents an important ecosystem service in agricultural systems. Recognizing the importance of bats to suppress pest populations and further conserve their populations near agricultural systems could reduce damage to crops thereby potentially increasing...
Chapter
We compared bat activity and bat species richness in remnants of the Coastal Mountain Range in central and southern Chile and evaluated seasonal variations in their distribution patterns. A total of seven bat species were recorded, of which Tadarida brasiliensis and Myotis chiloensis were the dominant species, followed by Lasiurus varius. Overall,...
Article
Landscape composition and heterogeneity are considered important factors for enhancing biodiversity and their associated ecosystem services in human-modified landscapes. Despite their roles in pest suppression in agricultural areas, insectivorous bats have been poorly represented in studies assessing the effects of landscape structural changes, par...
Article
Agricultural intensification is one of the major causes for the global loss of biodiversity and associated ecosystem services. As an alternative to conventional farming, organic management is considered a way to mitigate some of the negative impacts on biodiversity in agricultural landscapes; however, their benefits for bats are not very conclusive...
Article
We recorded and characterized the echolocation calls emitted by the common vampire bat Desmodus rotundus during foraging in natural habitats in Chile. Signal design typically shows multiple harmonics consisting of a brief quasi-constant frequency (QCF) component at the beginning of the pulse followed by a downward frequency modulated component. Cal...

New records and extension of the latitudinal range of Tadarida brasiliensis (Chiroptera: Molossidae) in Chile. The Brazilian free-tailed bat Tadarida brasiliensis is one of the most widely distributed species of bats in Chile, where it is known from numerous records from the region of Arica and Parinacota (18oS) southward to Riñihue, Los Ríos Regio...
Article
Full-text available
Bats in Chile have not been extensively studied as other zoological groups, along with it, added the threats they face and their incorporation into baseline studies of environmental impact line, a guide is necessary to standardized methodology for study. We recommend when studying bats use sampling techniques taking into account the behavior, diet,...

Bats are one of the least studied groups of vertebrates in Chile; however, in recent years the knowledge about them has advanced significantly due to the implementation of bioacoustics methods as well as by the recent inclusion of bats in environmental impact studies. Here we update the list of Chilean bats, raising to 13 the number of previously k...

Se realiza una revisión bibliográfica del estado taxonómico de Lasiurus borealis varius en Chile. Se considera a Lasiurus varius como especie válida, y no como una subespecie de L. borealis, por lo tanto esta última no debería ser incluida dentro de los quirópteros presentes en Chile.

The Brazilian free-tailed bat Tadarida brasiliensis is one of the most widely distributed species of bats in Chile, where it is known from numerous records from the region of Arica and Parinacota (18oS) southward to Riñihue, Los Ríos Region (39oS). We report new localities for T. brasiliensis in Chile, extending the geographical range of the specie...

Myotis atacamensis is a vespertilionid bat known from western Peru to northern and central Chile, where it is usually associated with coastal deserts. Here, we report the southernmost record of the species, extending its geographical distribution by 160 km. This represents the first observation of M. atacamensis in the temperate sclerophyllous fore...

The American kestrel (Falco sparverius) is a raptor widely distributed in America. Throughout its geographic distribution, the American kestrel feeds on a variety of animal taxa, including bats. In Chile, however, there are no reports of American kestrel feeding on bats. This note reports the first known record of predation by the American kestrel...

Myotis atacamensis is a poorly known bat species endemic to the central portion of the pacific coast of South America, where it is known from the province of Lambayeque, Peru (latitude 5° S), to the province of Elqui (latitude 30° S), Chile. Here, we report the first record of M. atacamensis for the province of Choapa (latitude 31° S, Coquimbo Regi...

The pattern of seed rain across a landscape can determine the distribution of potential recruitment rates, influencing the spatial processes of colonization, range expansion and gene flow. Likewise, the quantification of propagule input and germination response in different micro-sites is of fundamental importance to the restoration of degraded pla...

Se presentan caracterizaciones taxonómicas, distribución geográfica e interacciones hospedero-patógeno asociados a murciélagos en Chile a partir del estudio de cinco sitios diferentes pertenecientes a tres ecorregiones del país: Bosque templado lluvioso valdiviano, Matorral Chileno y el Desierto de Atacama. Se recolectaron un total de 26 murciélagos correspondientes a tres especies (Histiotus magellanicus, Myotis chiloensis y Desmodus rotundus) a partir de los cuales se recuperaron un total de 142 artrópodos. Este estudio preliminar sugiere investigaciones más completas a futuro sobre las metacomunidades de ectoparásitos en quirópteros y su caracterización taxonómica específica, en diversos biotipos ubicados en diferentes latitudes de Chile.
