Chiroptera of Buenos Aires City and Buenos Aires Province, Argentina

Abstract

Chiroptera of Ruenos Airos City and Buenos Aires Province, Argentina. The distribution of thirteen species dbats inBuenos Aires City and Fuenos Aires Province is provided based on scientific collections and bibliographical data. Three families are reported: Phyllostomidae, with one genus and one species; Vespertilionidae, with four genera and eight species, and Molossidae, with four genera and four species. Inlormation on taxonomy, specimens examined and additional records, external a n d cranial morphological measiirements. reproduction, habitat preferences, predation by owls, and public health importance as rabies reservoirs, arc provided in individual species accounts.

Lasiurus villosissimus (Chiroptera: Vespertilionidae)

“…In Argentina, pregnant Lasiurus villosissimus were detected in August (two fetuses), November (two fetuses), and January (one fetus). Females with offspring were detected in November (two offspring), December (two offspring), and September (one offspring); juvenile females have been recorded in December and reproductive males were found in mid-November; births could occur from September to March (Sanborn and Crespo 1957; Barquez et al 1999; Vaccaro and Varela 2001). In central Chile, a female with two offspring was recorded in early December by two of us (AR-SP and JLA).…”

“…Some diseases associated with L. villosissimus are leishmaniasis in Brazil (Castro et al 2020) and rabies in most South American countries (Vaccaro and Varela 2001; Cunha et al 2006; Escobar et al 2015; Llanos-Soto and González-Acuña 2019); only the latter being transmissible to humans. Regarding ectoparasites, L .…”

“…Silva (1985) mentioned for Rio Grande do Sul, Brazil, a possible migration from the north that reaches the highlands, mountain area ("campo serrano"), and central depression (Bianconi and Pedro 2007). Because all specimens from Buenos Aires (Argentina) were collected between September and April and only one record in August, Vaccaro and Varela (2001) suggested that during the colder months it migrates to warmer latitudes. According to Sanborn and Crespo (1957), L. villosissimus performs seasonal and elevational migrations on the western slopes of the Andes in Chile and northern South America.…”

“…Some diseases associated with L. villosissimus are leishmaniasis in Brazil (Castro et al 2020) and rabies in most South American countries (Vaccaro and Varela 2001;Cunha et al 2006;Escobar et al 2015;Llanos-Soto and González-Acuña 2019); only the latter being transmissible to humans. Regarding ectoparasites, L. villosissimus can host mites such as Olabidocarpus americanus (Chirodiscidae), Acanthophthirius lasiurus, and Pteracarus completus (Myobiidae), flies, for example, Basilia ferruginia (Nycteribiidae- Whitaker and McCracken 2001), and a soft tick, Ornithodoros hasei (Schulze-Argasidae, Acari) was also recorded (Marinkelle and Grose 1981).…”

Whey Revalorization through the Development of Spreadable Cheeses

“…El lactosuero se define como la fracción de la leche de cualquier especie que no precipita debido a la acción del cuajo o de los ácidos durante el proceso de elaboración de quesos, y que contiene componentes de alto valor nutricional (aproximadamente el 50% de los nutrientes de la leche original) [1,2]. Tradicionalmente, se lo consideraba como un elemento no deseable, de escaso interés y de alto costo de eliminación, por lo que la práctica más común ha sido sencillamente verterlo en los cursos de agua, lo que es muy perjudicial desde el punto de vista ambiental ya que alcanza valores de DQO y DBO 5 de 60-80 y 30-50 kg m −3 , respectivamente; fuerza contaminante equivalente a la de las aguas negras producidas en un día por aproximadamente 500 personas [3,4,5].…”
