Additional information is provided on several species of bats alrea dy known to occ ur in Suriname, including Micronycteris minuta , M . nicefori, Phylloderma stenops, Tonatia biden s, T. brasilien se , T. carrikeri, Ya mpyrum spectrum . Anoura caudifer, Caro/lia brevicauda , Rhinoph ylla pumilio, Vampyressa bidens, and Lasiurus ega. INTRODUCTION In his classical work, Hus son (1962) reported 58 species of bats as occurring in Suriname. In The Mammals of Suriname, Hu sson (1978) brought the number of species of bats to 60 (excluding Myotis suri­ nam ensis, see LaVal, 1973a). The total subsequently was raised to 70 by Genoways and Williams (1979). Finally, with the recent description Submitted for publi cation 28 December 1979. 213 214 ANNALSOF CARNEGIE MUSEUM VOL. 49 of Tonatia schulzi (Genoways and Williams , 1980), the chiropteran fau­ na, prior to the work described herein, consisted of 71 species. Our material resulted from fieldwork in Suriname that was con­ ducted primarily between 10 August and 9 October 1979, which re­ sulted in the collection of 960 specimens of bats representing approx­ imately 62 species. Fourteen of the se never have been reported from Suriname, although Husson (1978) speculated that four of the species probably occurred in the country. These new records are discussed below. Information also is provided for 12 other species of bats, all previously reported from Suriname, which adds significantly to data available in previous works (Husson, 1962, 1978; Genoways and Wil­ liams, 1979). The number of bat species known to occur in Suriname is now 85. METHODS AND MATERIALS All of our specimens, unless otherwise indicated, were captured in mist nets in the months of August , September, and October 1979, and were prepared as fluid-pre served specimens or as sta ndard museum skins accompanied by skulls. Supplimental data re­ corded for most of these specimens included standard karyot ypes, live tissue for chro­ mosomal banding, frozen tissue for electrophoretic analysis, and tissue for anatomical studies. The specimens are deposited in the Section of Mamm als of Carnegie Museum of Natural History and synoptic series will be returned to Suriname in care of STINASU for deposition in their refe rence collection. Forearm and cranial dimen sions were taken with dial calipers accurate to 0.1 rnrn . Unless otherwise indicated, all specimens are con sidered to be adults as indicated by completely fused phalangeal epiph yses. Measurements taken in this study included length of forearm , greatest length of skull, condylobasal length, zygomatic breadth, mastoid breadth, postorbital breadth, length of maxillary toothrow, and breadth across upper molars. Genoways and Williams (1979) have described how the se measurements are taken. Statistics presented in this study were calculated with a Texas Instruments SR-5IA calculator. Field weights in gram s were taken with Pesola spring scales. The reproductive con­ dition of skin/skull specimens was determined by gross disse ction in the field, whereas fluid-pre served specimens were dissected in the laboratory.Crown-rump length of fe­ tuses and testes lengths of males are given in millimeters. A CKNOWLEDGMENTS Our fieldwork in Surin ame in 1979 was supported by a grant from the Alcoa Foun­ dation , Charles L. Griswold, President. We gratefully acknowledge this support. Our fieldwork in 1977 was supported by the M. Graham Netting Research Fund through a grant from the Cordelia Scaife May Charitable Trust. We would like to thank Dr. Joop P. Schu lz and Henry A. Reichart, STINASU, for their assistance during our work and for making the many facilities of STINASU avail­ able to us. Without their help , our work in Surin ame would have been impos sible. Ferdinand L. J. Baal , Department of Forestry, issued our permits. Mr. Leo Roberts, STINASU, pro ved to be an excellent field guide and a most congenial companion. The personnel of Surinaams Museum of Natural History, parti cularly Marga Werkhoven, and Mr. I. Douglas, were helpful in making hous ing and laboratory facilit ies available for our use . Mr. E. W. Ken smil of the Airports and Civil Aviation was of great assistance in providing some of our air transportation to the country's interior.

SPECIES ACCOUNTS Pteronotus personatus personatus (Wagner) Specimens examined (2).-NICKERtE: Grassalco, 4°46'N , 56°46'W, 2. Rem arks.-Our specimens of P. persona/u s are the first to be re­ ported from Suriname and confirm speculations of Husson (1962, 1978) that this species occurs in the country. Our records extend the known range of the species in South America about 700 km to the southeast. At the present time two species of Pteronotus are known to occur in Suriname-Po parnellii and P. persona/u s (Huss on, 1962, 1978; Gen­ oways and Williams, 1979). These spec ies are easily differentiated by size. Both specimens of P. personatus , a male and female , were collected between 2000 and 2030 hours on 7 September. The male weighed 8 and had testes that measured 5; the female weighed 9 and was not pregnant. The collecting locality was located along a small river, about 15 m wide , with many logs and boulders protruding from the surface of the water. The surrounding vegetation consi sted of secondary trop­ ical jungle and hardwood forest. Mist nets were set up in the vicinity ofthe Grassalco headquarters buildings, across the river in three areas, and along a trail that passed through a hardwood forest in which all undergrowth had been cleared . The trail was about 50 m from the river. Species of bats collected over the river with our specimens of P. personatus included Rh ynchonycteris naso , Noctilio leporinus , Anoura caudifer, Choeroniscus interm ediu s , Lonchoph ylla thom asi, Artibeus cinereus , two large species of A rtibeus (currently under in­ vestigat ion to determine taxonomic relationships), Chiroderma trini­ tatum , Vampyress a brocki , Vampyrops helleri, Myotis albescens, Mo­ lossops abrasus, M . gree nhalli, and Molossus molossus. Species collected in the adjacent forest included Pteronotu s parnellii, Tonatia bidens, An oura cau difer, Carollia brevicauda, C. perspicillata , two large species of Artibeus, and Sturnira lilium . We follow the review of the famil y Mormoopidae by Smith (1972) in using Pteronotus for the generic name of personatus instead of Chilonycteris, as was used by Husson (1962, 1978). The name Chilo­ nycteris is considered by Smith (1972) to be a subgenus of Pteronotus. The subspecies P. p. personatus has been reported pre viou sly from 216 ANNALS OF CARNEGIE M USEUM VO L. 49 Costa Rica, Pan ama, Colombia, Venezuela, and Trinidad (Smith, 1972). External and cranial measurements of our two specimens (male fol­ lowed by female) are as follows: length of forearm, 48.4 , 48.9; greatest length of skull , 16.2, 16.7; condylobasal length, 14.8, 15.2; zygomatic breadth, 9.0, 9.1; mastoid breadth, 8.7, 9.1; postorbital breadth, 3.5, 3.5; length of maxillary toothrow, 6.6, 6.1; breadth across upper mo­ lars, 6.2, 6.0.

  • Greater Spear-Nosed Bats Discriminate Group Mates by Vocalizations
    Anim. Behav., 1998, 55, 1717–1732 Greater spear-nosed bats discriminate group mates by vocalizations JANETTE WENRICK BOUGHMAN*† & GERALD S. WILKINSON* *Department of Zoology, University of Maryland, College Park †Department of Zoological Research, National Zoological Park, Smithsonian Institution (Received 20 May 1997; initial acceptance 18 August 1997; final acceptance 23 October 1997; MS. number: 7930) Abstract. Individuals often benefit from identifying their prospective social partners. Some species that live in stable social groups discriminate between their group mates and others, basing this distinction on calls that differ among individuals. Vocalizations that differ between social groups are much less common, and few studies have demonstrated that animals use group-distinctive calls to identify group mates. Female greater spear-nosed bats, Phyllostomus hastatus, live in stable groups of unrelated bats and give audible frequency, broadband calls termed screech calls when departing from the roost and at foraging sites. Previous field observations suggested that bats give screech calls to coordinate movements among group members. Prior acoustic analyses of 12 acoustic variables found group differences but not individual differences. Here, we use the same acoustic variables to compare calls from three cave colonies, and find that calls differ between caves. We also report results from field and laboratory playback experiments designed to test whether bats use acoustic differences to discriminate calls from different colonies, groups or individuals. Results from field playbacks indicate that response depends on the cave of origin, indicating that bats can discriminate among calls from different caves. This discrimination ability may be based, in part, on whether calls are familiar or unfamiliar to the listening bats.

  • Costa Rica Trip Report: Apr/May 2019
    Costa Rica Trip Report: Apr/May 2019 Julio Balona Itinerary 1st Route . La Selva Biological Station . Tirimbina Lodge . Bosque de Paz Lodge . Paraiso Quetzal Lodge 2nd Route . Danta Corcovado Lodge . La Leona Eco Lodge . Saladero Eco Lodge . Hacienda Baru/Damas Island/Damas Caves Some notes . Lodges were booked online beforehand, either directly on the lodge website or through Booking.com. These were all booked separately except for Danta/La Leona/Saladero which was a three lodge package for which we were collected at Puerto Jimenez and returned there afterward. We hired a car from Alamo for the first route ending at Puerto Jimenez, and then again a week later after returning from Danta/La Leona/Saladero for the second route. Alamo is the only big name car rental company in Puerto Jimenez as far as I know. We (my wife and I) landed at the San Jose airport around lunch time. After drawing colones from one of the ATMs which would be useful for certain purchases, we then bought a SIM card with the intention of using the Waze navigation app. Unfortunately the network was down so the card would only be activated the next day. We therefore took the GPS option on the hire car, but this worked well enough. A shuttle was available to take us from the Alamo booth at the San Jose airport to their offices a few kilometres away. This was a pleasant surprise because we did not know about this service and had planned to do so by taxi. Our experience with Alamo was quite satisfactory overall although both the cars we used were far from new (not serious) and it now appears to me that we may have been charged a collection fee that was never discussed with us (serious).

  • Chromosomal Evolution and Phylogeny in the Nullicauda Group
    Gomes et al. BMC Evolutionary Biology (2018) 18:62 https://doi.org/10.1186/s12862-018-1176-3 RESEARCHARTICLE Open Access Chromosomal evolution and phylogeny in the Nullicauda group (Chiroptera, Phyllostomidae): evidence from multidirectional chromosome painting Anderson José Baia Gomes1,3, Cleusa Yoshiko Nagamachi1,4, Luis Reginaldo Ribeiro Rodrigues2, Malcolm Andrew Ferguson-Smith5, Fengtang Yang6, Patricia Caroline Mary O’Brien5 and Julio Cesar Pieczarka1,4* Abstract Background: The family Phyllostomidae (Chiroptera) shows wide morphological, molecular and cytogenetic variation; many disagreements regarding its phylogeny and taxonomy remains to be resolved. In this study, we use chromosome painting with whole chromosome probes from the Phyllostomidae Phyllostomus hastatus and Carollia brevicauda to determine the rearrangements among several genera of the Nullicauda group (subfamilies Gliphonycterinae, Carolliinae, Rhinophyllinae and Stenodermatinae). Results: These data, when compared with previously published chromosome homology maps, allow the construction of a phylogeny comparable to those previously obtained by morphological and molecular analysis. Our phylogeny is largely in agreement with that proposed with molecular data, both on relationships between the subfamilies and among genera; it confirms, for instance, that Carollia and Rhinophylla, previously considered as part of the same subfamily are, in fact, distant genera. Conclusions: The occurrence of the karyotype considered ancestral for this family in several different branches

    Zoology 104 (2001): 59–73 © by Urban & Fischer Verlag http://www.urbanfischer.de/journals/zoology Diet and the evolution of digestion and renal function in phyllostomid bats Jorge E. Schondube1,*, L. Gerardo Herrera-M.2 and Carlos Martínez del Rio1 1Department of Ecology and Evolutionary Biology, University of Arizona, Tucson 2Instituto de Biología, Departamento de Zoología, Universidad Nacional Autónoma de México, México Received: April 2, 2001 · Accepted: April 12, 2001 Abstract Bat species in the monophyletic family Phyllostomidae feed on blood, insects, small vertebrates, nectar, fruit and complex omnivorous mixtures. We used nitrogen stable isotope ratios to characterize bat diets and adopted a phylogenetically informed approach to investi- gate the physiological changes that accompany evolutionary diet changes in phyllostomids. We found that nitrogen stable isotopes sep- arated plant-eating from animal-eating species. The blood of the latter was enriched in 15N. A recent phylogenetic hypothesis suggests that with the possible exception of carnivory, which may have evolved twice, all diets evolved only once from insectivory. The shift from insectivory to nectarivory and frugivory was accompanied by increased intestinal sucrase and maltase activity, decreased trehalase activity, and reduced relative medullary thickness of kidneys. The shift from insectivory to sanguinivory and carnivory resulted in re- duced trehalase activity. Vampire bats are the only known vertebrates that do not exhibit intestinal maltase activity. We argue that these physiological changes are adaptive responses to evolutionary diet shifts. Key words: Bats, comparative method, diet, digestive and renal function, stable isotopes. Introduction The family Phyllostomidae is a speciose (49 genera and Characterizing animal diets can be difficult.

He¡ner Ã, Gimseong Koay, Henry E. He¡ner Department of Psychology, University of Toledo, Toledo, OH 43606, USA Received 10 March 2003; accepted 23 July 2003 Abstract We determined the audiogram of the Jamaican fruit-eating bat (Phyllostomidae: Artibeus jamaicensis), a relatively large (40^50 g) species that, like other phyllostomids, uses low-intensity echolocation calls. A conditioned suppression/avoidance procedure with a fruit juice reward was used for testing. At 60 dB SPL the hearing range of A. jamaicensis extends from 2.8 to 131 kHz, with an average best sensitivity of 8.5 dB SPL at 16 kHz. Although their echolocation calls are low-intensity, the absolute sensitivity of A. jamaicensis and other ‘whispering’ bats does not differ from that of other mammals, including other bats. The high-frequency hearing of A. jamaicensis and other Microchiroptera is slightly higher than expected on the basis of selective pressure for passive sound localization. Analysis suggests that the evolution of echolocation may have been accompanied by the extension of their high-frequency hearing by an average of one-half octave. With respect to low-frequency hearing, all bats tested so far belong to the group of mammals with poor low-frequency hearing, i.e., those unable to hear below 500 Hz. ß 2003 Elsevier B.V.
