(Uploaded by Plazi for the Bat Literature Project) We present a case of chromatic disorder observed in a specimen of Trachops cirrhosus from lowland forests of the Ecuadorian Amazon. During the field work, six individuals of this species were captured with mist nets in an intervened habitat, of which, a juvenile male specimen was distinguishable from the rest of the individuals due to the presence of whitish spots on the ventral region, on the chest and abdomen. We discuss the previous reports of this type of pigmentary disorders in bats from Ecuador, and in the Neotropic, documenting the first record of Trachops cirrhosus with this condition for the country.

Piebaldism is a genetic pigmentation disorder, which is caused by absence of melanocytes in parts of the skin and/or hair follicles, with eyes and claws normally pigmented. The occurrence of piebaldism in natural populations is rare and the effects on fitness are still unknown. This article reports the first case of pigmentation disorders in the Fringe-lipped Bat Trachops cirrhosus (Spix, 1823) (Chiroptera: Phyllostomidae) caught in Barra do Triunfo, city of João Neiva, northeastern state of Espírito Santo, southeast Brazil.

(Uploaded by Plazi for the Bat Literature Project) Abstract Some bat species in the families Phyllostomidae, Megadermatidae, and Nycteridae have long been known to consume terrestrial vertebrates and, more recently, reports of aerial‐hawking vespertilionid carnivores have surfaced. We review the diets, hunting behaviour and roosting ecology of 17 bat species that are known to consume terrestrial vertebrates: Vampyrum spectrum, Chrotopterus auritus, Trachops cirrhosus, Macroderma gigas, Megaderma (Lyroderma) lyra, Nycteris grandis, Nyctalus lasiopterus, Nyctalus aviator, Ia io, Antrozous pallidus, Cardioderma cor, Phyllostomus hastatus, Mimon (Gardnerycteris) crenulatum, Mimon cozumelae, Tonatia saurophila, Tonatia bidens, and Lophostoma silvicolum . Data on their diet and roosts were obtained from 241 original works, with considerable differences in the amount of research and information available among species. Carnivorous bats were found to belong to an ecologically diverse group and share little but their diet. Therefore, we define a carnivorous bat as a bat that, either year‐round or seasonally, uses terrestrial vertebrates as the main component of its diet, at least in part of its geographic range. We conclude from available data that Mimon crenulatum, Lophostoma silvicolum, Mimon cozumelae, Phyllostomus hastatus, Tonatia bidens, Tonatia saurophila, Cardioderma cor , and Antrozous pallidus use vertebrates as a minor part of their diet and should not be considered carnivorous. The nine other species we reviewed do fit into the definition of carnivorous bats, and can be further subdivided based on their ecology and the seasonality of their habits into three categories: year‐round predominantly gleaning carnivores ( Chrotopterus auritus , Trachops cirrhosus , and Vampyrum spectrum ), seasonal predominantly gleaning carnivores ( Megaderma lyra, Macroderma gigas, and Nycteris grandis ) and seasonal aerial‐hawking bird‐eating carnivores ( Ia io, Nyctalus aviator, and Nyctalus lasiopterus ). , Resumen en Español Se sabe desde hace tiempo que algunas especies de murciélagos en las familias Phyllostomidae, Megadermatidae y Nycteridae consumen vertebrados terrestres. Más recientemente, también se ha reportado esta dieta entre vespertiliónidos que cazan al vuelo. En este trabajo se revisan las dietas, comportamiento de cacería y ecología de los refugios de 17 especies de murciélagos que se sabe consumen vertebrados terrestres: Vampyrum spectrum, Chrotopterus auritus, Trachops cirrhosus, Macroderma gigas, Megaderma (Lyroderma) lyra, Nycteris grandis, Nyctalus lasiopterus, Nyctalus aviator, Ia io, Antrozous pallidus, Cardioderma cor, Phyllostomus hastatus, Mimon (Gardnerycteris) crenulatum, Mimon cozumelae, Tonatia saurophila, Tonatia bidens y Lophostoma silvicolum . Se obtuvo información sobre sus dietas y refugios a partir de 241 trabajos, con diferencias considerables en cuánta información hay disponible para cada especie Los murciélagos carnívoros son un grupo ecológicamente diverso que comparte pocas características además de la dieta. Por lo tanto, definimos a un murciélago carnívoro como un murciélago que, ya sea todo el año o estacionalmente, consume vertebrados terrestres como el componente principal de su dieta al menos en parte de su distribución geográfica. Concluimos, a partir de los datos disponibles, que Mimon crenulatum, Lophostoma silvicolum, Mimon cozumelae, Phyllostomus hastatus, Tonatia bidens, Tonatia saurophila, Cardioderma cor y Antrozous pallidus consumen vertebrados como una parte minoritaria de la dieta y no deben ser considerados carnívoros. Las nueve especies restantes sí satisfacen nuestra definición de murciélago carnívoro, pero pueden clasificarse con base en su ecología y la estacionalidad de sus hábitos en tres categorías: carnívoros anuales predominantemente acechadores ( Chrotopterus auritus , Trachops cirrhosus y Vampyrum spectrum ), carnívoros estacionales predominantemente acechadores ( Megaderma lyra, Macroderma gigas y Nycteris grandis ) y carnívoros ornitófagos estacionales aéreos ( Ia io, Nyctalus aviator y Nyctalus lasiopterus ).

Annotation:

General insights into the causes and effects of social structure can be gained from comparative analyses across socially and ecologically diverse taxa, such as bats, but long-term data are lacking for most species. In the neotropical fringe-lipped bat, Trachops cirrhosus , social transmission of foraging behaviour is clearly demonstrated in captivity, yet its social structure in the wild remains unclear. Here, we used microsatellite-based estimates of relatedness and records of 157 individually marked adults from 106 roost captures over 6 years, to infer whether male and female T. cirrhosus have preferred co-roosting associations and whether such associations were influenced by relatedness. Using a null model that controlled for year and roosting location, we found that both male and female T. cirrhosus have preferred roosting partners, but that only females demonstrate kin-biased association. Most roosting groups (67%) contained multiple females with one or two reproductive males. Relatedness patterns and recapture records corroborate genetic evidence for female philopatry and male dispersal. Our study adds to growing evidence that many bats demonstrate preferred roosting associations, which has the potential to influence social information transfer.

Annotation:

(Uploaded by Plazi for the Bat Literature Project) While foraging, eavesdropping predators home in on the signals of their prey. Many prey signal from aggregations, however, and predators already en route to attack one individual often encounter the signals of other prey. Few studies have examined whether eavesdropping predators update their foraging decisions by switching to target these more recently signaling prey. Switching could result in reduced localization errors and more current estimates of prey location. Conversely, assessing new cues while already in pursuit of another target might confuse or distract a predator. We tested whether fringed-lipped bats (Trachops cirrhosus) switch prey targets when presented with new cues mid-approach and examined how switching and the distance between simulated prey influence attack accuracy, latency, and prey capture success. During nearly 80% of attack flights, bats switched between túngara frog (Engystomops pustulosus) calls spaced 1 m apart, and switching resulted in lower localization errors. The switching rate was reduced, and the localization advantage disappeared for calls separated by 3 m. Regardless of whether bats switched targets, attacks were less accurate, took longer, and were less often successful when calls were spaced at larger distances, indicating a distraction effect. These results reveal that fringed-lipped bats attend to cues from non-targeted prey during attack flights and that the distance between prey alters the effectiveness of attacks, regardless of whether a bat switches targets. Understanding how eavesdropping predators integrate new signals from neighboring prey into their foraging decisions will lead to a fuller picture of the ways unintended receivers shape the evolution of signaling behavior.

Annotation:

(Uploaded by Plazi for the Bat Literature Project) Phyllostomidae comprises the most diverse family of neotropical bats, its wide range of morphological features leading to uncertainty regarding phylogenetic relationships. Seeing that cytogenetics is one of the fields capable of providing support for currently adopted classifications through the use of several markers, a comparative analysis between two Phyllostomidae species was undertaken in the present study, with a view to supplying datasets for the further establishment of Phyllostomidae evolutionary relationships. Karyotypes of Lonchorhina aurita (2n = 32; FN = 60) and Trachops cirrhosus (2n = 30; FN = 56) were analyzed by G- and C-banding, silver nitrate staining (Ag-NOR) and base-specific fluorochromes. Chromosomal data obtained for both species are in agreement with those previously described, except for X chromosome morphology in T. cirrhosus, hence indicating chromosomal geographical variation in this species. A comparison of G-banding permitted the identification of homeologies in nearly all the chromosomes. Furthermore, C-banding and Ag-NOR patterns were comparable to what has already been observed in the family. In both species CMA3/DA/DAPI staining revealed an R-banding-like pattern with CMA3, whereas DAPI showed uniform staining in all the chromosomes. Fluorochrome staining patterns for pericentromeric constitutive heterochromatin (CH) regions, as well as for nucleolar organizing regions (NORs), indicated heterogeneity regarding these sequences among Phyllostomidae species.

(Uploaded by Plazi for the Bat Literature Project) While foraging, eavesdropping predators home in on the signals of their prey. Many prey signal from aggregations, however, and predators already en route to attack one individual often encounter the signals of other prey. Few studies have examined whether eavesdropping predators update their foraging decisions by switching to target these more recently signaling prey. Switching could result in reduced localization errors and more current estimates of prey location. Conversely, assessing new cues while already in pursuit of another target might confuse or distract a predator. We tested whether fringed-lipped bats (Trachops cirrhosus) switch prey targets when presented with new cues mid-approach and examined how switching and the distance between simulated prey influence attack accuracy, latency, and prey capture success. During nearly 80% of attack flights, bats switched between túngara frog (Engystomops pustulosus) calls spaced 1 m apart, and switching resulted in lower localization errors. The switching rate was reduced, and the localization advantage disappeared for calls separated by 3 m. Regardless of whether bats switched targets, attacks were less accurate, took longer, and were less often successful when calls were spaced at larger distances, indicating a distraction effect. These results reveal that fringed-lipped bats attend to cues from non-targeted prey during attack flights and that the distance between prey alters the effectiveness of attacks, regardless of whether a bat switches targets. Understanding how eavesdropping predators integrate new signals from neighboring prey into their foraging decisions will lead to a fuller picture of the ways unintended receivers shape the evolution of signaling behavior.

(Uploaded by Plazi for the Bat Literature Project) Phyllostomidae comprises the most diverse family of neotropical bats, its wide range of morphological features leading to uncertainty regarding phylogenetic relationships. Seeing that cytogenetics is one of the fields capable of providing support for currently adopted classifications through the use of several markers, a comparative analysis between two Phyllostomidae species was undertaken in the present study, with a view to supplying datasets for the further establishment of Phyllostomidae evolutionary relationships. Karyotypes of Lonchorhina aurita (2n = 32; FN = 60) and Trachops cirrhosus (2n = 30; FN = 56) were analyzed by G- and C-banding, silver nitrate staining (Ag-NOR) and base-specific fluorochromes. Chromosomal data obtained for both species are in agreement with those previously described, except for X chromosome morphology in T. cirrhosus, hence indicating chromosomal geographical variation in this species. A comparison of G-banding permitted the identification of homeologies in nearly all the chromosomes. Furthermore, C-banding and Ag-NOR patterns were comparable to what has already been observed in the family. In both species CMA3/DA/DAPI staining revealed an R-banding-like pattern with CMA3, whereas DAPI showed uniform staining in all the chromosomes. Fluorochrome staining patterns for pericentromeric constitutive heterochromatin (CH) regions, as well as for nucleolar organizing regions (NORs), indicated heterogeneity regarding these sequences among Phyllostomidae species.

Investigaciones sobre toxicidad ambiental por pesticidas se han realizado principalmente en mamíferos terrestres, pero existe poca información sobre plaguicidas organoclorados en murciélagos. Teniendo en cuenta el papel funcional de este grupo en varios procesos ecosistémicos como insectívoros, frugívoros y polinizadores, su afectación puede estar causando un impacto negativo en la salud de los ecosistemas naturales. En Colombia, no hay estudios que documenten esta problemática; por tanto, el objetivo fue determinar la presencia de plaguicidas organoclorados en el ensamblaje de murciélagos del bosque húmedo tropical (bh-T) en Córdoba, Colombia. Se evaluó la presencia de organoclorados en hígado y músculo de murciélagos del sector Manso-Tigre, un área protegida con ocupación campesina. La concentración de plaguicidas organoclorados como Aldrin, Dieldrin, Endrin, Heptacloro epóxido, α-BCH, βBCH, γ-BCH, 2,4-DDD, 2,4-DDT, 4,4-DDE y 4,4-DDT, se determinó por cromatografía de gases. Niveles de organoclorados en hígado y músculo presentaron diferencias significativas (P<0,05). Se detectó mayor contenido de organoclorados en hígado en las especies Trachops cirrhosus (α–BCH, γ-BCH, Endrin, pp-DDE), Desmodus rotundus (β-BCH), Micronycteris microtis (Aldrin), Platyrrhinus helleri (Heptacloro) y Phyllostomus hastatus (pp-DDT). En tejido muscular, la concentración de organoclorados fue mayor en Trachops cirrhosus (α-BCH, γ-BCH, Endrin, pp-DDE), Artibeus planirostris (β-BCH), Micronycteris microtis (Aldrin, Heptacloro) y Phyllostomus hastatus (pp-DDT). La contaminación por organoclorados en murciélagos posiblemente está relacionada con el uso de agroquímicos, insecticidas y compuestos fosfatados para uso agrícola. Los resultados permiten reconocer a los murciélagos como bioindicadores de contaminación ambiental al indicar procesos de cambios o disturbios en los hábitats.

The aim of this paper is to evaluate the taxonomic diversity of fossil and extant bats from the region of the Serra da Mesa in the State of Goias, Central Brazil. Quaternary fossils were obtained from four limestone caves, namely Igrejinha, Carneiro, Nossa Senhora Aparecida, and Itambé. Information on extant bat fauna used for comparison were obtained from literature and from the collection of Museu Nacional (Rio de Janeiro). The taxonomic identification of the fragments was based on a comparative study of the masticatory apparatus of extant and fossil bat species. A total of 430 fragments were identified, comprising 27 species: Anoura geoffroyi, Artibeus sp., Carollia sp., Chrotopterus auritus, Desmodus rotundus, Desmodus sp., Emballonuridae sp. indet., Eptesicus/ Histiotus, Glossophaga sp., Lionycteris spurrelli, Lonchorhina aurita, Micronycteris megalotis, Mimon bennetti, Mimon crenulatum, Molossidae sp. indet., Myotis sp., Natalus stramineus, Phylloderma sp. n., Phyllostomus discolor, Phyllostomus hastatus, Platyrrhinus sp., Pteronotus davyi, Pteronotus parnelli, Sturnira sp., Tonatia sp. n., Lophostoma silvicola, and Trachops cirrhosus. Phyllostomidae was the most speciose family, but surprisingly most of the fossil fragments were attributed to the families Natalidae and Mormoopidae. Both of which are rare in the area today. The population reduction of these hot-humid-cave dwelling species (Natalus and Pteronotus) may suggest the climate of the area was warmer and wetter during some interval of the Late Pleistocene or Early Holocene. This study presents the first record of the genera Lionycteris, Lonchorhina and Trachops from the Quaternary of South America. The diversity of Chiroptera found in Serra da Mesa is equivalent to that described for Bahia, which heretofore has the most abundant record for Quaternary bats from South America.

(Uploaded by Plazi for the Bat Literature Project) Research on environmental toxicity due to the use of pesticides have been carried out mainly in terrestrial mammals but there is little information related to organochlorine pesticides in bats, that, taking into account the functional role of these animals as insectivores, frugivorous, and pollinators, it may probably be causing a negative impact on the health of natural ecosystems. In Colombia, there are no studies that document this problem. The objective was to determine the presence of organochlorine pesticides in the bat assembly of tropical rainforest in Córdoba, Colombia. The presence of organochlorine pesticides in liver and bat muscle of the Manso-Tigre sector, an area of bh-T with peasant occupation, was evaluated. The concentration of organochlorine pesticides such as Aldrin, Dieldrin, Endrin, Heptachlor epoxide, -BCH, BCH, γ-BCH, 2,4-DDD, 2,4-DDT, 4,4-DDE and 4,4-DDT, was determined by gas chromatography. Organochlorine levels in liver and muscle, presented significant statistical differences (P <0.05). Higher organochlorine content in the liver was detected in the species Trachops cirrhosus (-BCH, γ-BCH, Endrin, pp-DDE), Desmodus rotundus (-BCH), Micronycteris microtis (Aldrin), Platyrrhinus helleri (Heptachlor) and Phyllostomus hastatus (pp-DDT); and in muscle tissue were Trachops cirrhosus (-BCH, γ-BCH, Endrin, pp-DDE), Artibeus planirostris (-BCH), Micronycteris microtis (Aldrin, Heptachlor) and Phyllostomus hastatus (pp-DDT). Organochlorine contamination in bats is possibly related to the use of agrochemicals, insecticides, and phosphate compounds for agricultural use. The results allow us to recognize the importance of bats as a bioindicator of environmental pollution by indicating processes of changes or disturbances in habitats.

(Uploaded by Plazi for the Bat Literature Project) Gene flow, maintained through natal dispersal and subsequent mating events, is one of the most important processes in both ecology and population genetics. Among mammalian populations, gene flow is strongly affected by a variety of factors, including the species' ability to disperse, and the composition of the environment which can limit dispersal. Information on dispersal patterns is thus crucial both for conservation management and for understanding the social system of a species. We used 16 polymorphic nuclear microsatellite loci in addition to mitochondrial DNA sequences (1.61 kbp) to analyse the population structure and the sex-specific pattern of natal dispersal in the frog-eating fringe-lipped bat, Trachops cirrhosus, in Central Panama. Our study revealed that—unlike most of the few other investigated Neotropical bats—gene flow in this species is mostly male-m ediated. Nevertheless, distinct genetic clusters occur in both sexes. In particular, the presence of genetic differentiation in the dataset only consisting of the dispersing sex (males) indicates that gene flow is impeded within our study area. Our data are in line with the Panama Canal in connection with the widening of the Río Chagres during the canal construction acting as a recent barrier to gene flow. The sensitivity of T. cirrhosus to human- induced habitat modifications is further indicated by an extremely low capture success in highly fragmented areas. Taken together, our genetic and capture data provide evidence for this species to be classified as less mobile and thus vulnerable to habitat change, information that is important for conservation management.

Abstract Chemical signals can play important roles in communication, and this is especially true for social mammals such as bats. Male fringe-lipped bats (Trachops cirrhosus) produce an odorous substance on their forearm, called forearm crust. Only adult males with descended testes produce forearm crust. This is thus a sexually dimorphic odour, which suggests that it is a sexually selected trait. Since males lack a specific gland on their forearm we sought to identify the source of the forearm crust. Our second aim was to test female and male preference for this trait. Based on gas chromatography and mass spectrometry analyses we tentatively identified several compounds that were exclusive to the forearm crust. We found that the chemical composition of the forearm crust was not mainly composed of chest gland secretions or urine. We conducted a y-maze odour preference experiment to test whether adult females and reproductive males preferred the odour of a male with forearm crust compared to the odour of a male without forearm crust. Contrary to our prediction we found that females did not approach the scent of a male with forearm crust more frequently than the scent of male without forearm crust. We found that males with forearm crust, however, preferred the odour of males without forearm crust. Overall our results suggest that in this Neotropical bat species, reproductive males could use odorous signals in the forearm crust to mediate interactions between reproductive males and potentially avoid costly competition for mates or aggression. In sum, our results shed light on the role that chemical mediated signals can play in mammalian social behaviour.

Abstract Metabarcoding of prey DNA from fecal samples can be used to design behavioral experiments to study the foraging behavior and sensory ecology of predators. The frog-eating bat, Trachops cirrhosus, eavesdrops on the mating calls of its anuran prey. We captured wild T. cirrhosus and identified prey remains in the bats’ fecal samples using DNA metabarcoding of two gene regions (CO1 and 16S). Bats were preying on frogs previously unknown in their diet, such as species in the genus Pristimantis, which occurred in 29% of T. cirrhosus samples. Twenty-three percent of samples also contained DNA of Anolis lizards. We additionally report apparently rare predation events on hummingbirds and heterospecific bats. We used results from metabarcoding to design acoustic and 3D model stimuli to present to bats in behavioral experiments. We show predatory responses by T. cirrhosus to the calls of the frog Pristimantis taeniatus and to the rustling sounds of anoles moving through leaf-litter, as well as attacks on a stuffed hummingbird and a plastic anole model. The combination of species-specific dietary information from metabarcoding analyses with behavioral responses to prey cues provides a unique window into the foraging ecology of predators that are difficult to observe in the wild.

(Uploaded by Plazi for the Bat Literature Project) Abstract Metabarcoding of prey DNA from fecal samples can be used to design behavioral experiments to study the foraging behavior and sensory ecology of predators. The frog-eating bat, Trachops cirrhosus, eavesdrops on the mating calls of its anuran prey. We captured wild T. cirrhosus and identified prey remains in the bats' fecal samples using DNA metabarcoding of two gene regions (CO1 and 16S). Bats were preying on frogs previously unknown in their diet, such as species in the genus Pristimantis, which occurred in 29% of T. cirrhosus samples. Twenty-three percent of samples also contained DNA of Anolis lizards. We additionally report apparently rare predation events on hummingbirds and heterospecific bats. We used results from metabarcoding to design acoustic and 3D model stimuli to present to bats in behavioral experiments. We show predatory responses by T. cirrhosus to the calls of the frog Pristimantis taeniatus and to the rustling sounds of anoles moving through leaf-litter, as well as attacks on a stuffed hummingbird and a plastic anole model. The combination of species-specific dietary information from metabarcoding analyses with behavioral responses to prey cues provides a unique window into the foraging ecology of predators that are difficult to observe in the wild.

(Uploaded by Plazi for the Bat Literature Project) Few data are available on the predation of amphibians, reptiles, and mammals by the fringe-lipped bat Trachops cirrhosus (Chiroptera: Phyllostomidae: Phyllostominae), in particular in Brazil, where ecological studies of this species are still incipient. This study presents an overview of the data available in the literature on the composition of the diet of T. cirrhosus, including data from a semiarid region. The first records of the predation of the anurans Corythomanthis greeningi (Hylidae), Pleurodema diplolister (Leiuperidae), Proceratophrys cristiceps (Cycloramphidae), Dermatonotus muelleri (Microhylidae), Pipa carvalhoi (Pipidae), Leptodactylus sp. (Leptodactylidae), the lizards Vanzosaura rubricauda (Gymnophytalmidae), Hemidactylus mabouia (Gekknonidae), and a rodent of the family Cricetidae are reported. Insects (33%) constitute the principal component of the diet of T. cirrhosus, while anuran amphibians contributed 23% of the items recorded, followed by birds (14%), mammals (10%), lizards (8%), and invertebrates (8%). This diversity of prey is typical of a generalist predator, which is relatively unaffected by seasonal fluctuations in the availability of prey. This is especially important in the semi-arid Caatinga biome, which is subject to prolonged periods of drought that result in a shortage of feeding resources.
