    First records of three species of Lasiurus Gray, 1831 (Chiroptera, Vespertilionidae) in Bolivia
    (Pensoft Publishers, 2024) Luis H. Acosta Salvatierra; José L. Poma-Urey; Kathrin Barboza-Marquez; Kathia Rivero; José Ochoa G.; Jorge Salazar‐Bravo
    Insectivorous bats of the family Vespertilionidae have been grouped into eight tribes, with Lasiurini showing an extensive distribution in South America. In Bolivia, three species of lasiurine bats have been reported: Lasiurus blossevillii (Lesson & Garnot, 1826), L. ega (Gervais, 1856), and L. villosissimus (É. Geoffroy St.-Hilaire, 1806). The morphological analyses of specimens of this genus deposited in Bolivian scientific collections and comparisons with specimens from other countries (including holotypes) prompt us to report the first records of three species: Lasiurus atratus Handley 1996, L. castaneus Handley 1960, and L. egregius (Peters, 1870) in Bolivia, expanding their known geographic ranges to the southwestern part of the Amazon.

    Habitat Use by Aerial Insectivorous Bats of External Areas of Barro Colorado Nature Monument, Panama
    (2014) Kathrin Barboza-Marquez; Luís F. Aguirre; José Carlos Pérez Zubieta; Elisabeth K. V. Kalko
    Aerial insectivorous bats comprises almost half of the community of neotropical species. They contribute to pests control and herbivory reduction and they do it mostly by using echolocation (active or passive) to find their prey. Through acoustic sampling we assessed the structure of aerial insectivorous bats in four microhabitats (upper and lower forest edge, and upper and lower open space) in external areas of Barro Colorado Nature Monument. Seven sites were chosen for sampling, each was visited four times, and bat recordings were made for up to four consecutive hours. We found differences in the structure of the communities foraging in the microhabitats, and a tendency of certain species to be associated with certain microhabitats. Species with preference for the forest edge (e.g. Saccopteryx bilineata )showed sharper echolocation calls of short duration, short pulse intervals, and a combination of components of FM (frequency modulation) and QCF (quasi-constant frequency). Species that showed a preference for open space (e.g. Noctilio leporinus ) have echolocation calls with lower frequency, long duration, long pulse intervals and QCF components combined with FM. Differences between both cases are due to the foraging strategy, where some bats prefer the upper and other the lower parts of the space. This result provides important information to the knowledge of resource partitioning in aerial insectivorous bat communities, as well as on the importance of having a standard protocol to improve the use of acoustic monitoring.

    Historia natural del murciélago cara de perro del Mato Grosso Neoplatymops mattogrossensis (Vieira, 1942) (Chiroptera: Molossidae) en Bolivia
    (2023) Luis H. Acosta Salvatierra; Kathia Rivero; José L. Poma-Urey; Yannet Condori; Martika A. Valdez Montaño; Kathrin Barboza-Marquez; Julia Schulze; Elena Melgares
    El murciélago cara de perro del Mato Grosso (Neoplatymops mattogrossensis), tiene hábitos muy pobremente conocidos. Presentamos datos sobre su historia natural (estructura poblacional, temperatura y humedad relativa en el interior y exterior de los refugios, dieta en base al análisis de muestras fecales) obtenidos en refugios de los predios de la Reserva Privada de Patrimonio Natural San Sebastián. Los refugios encontrados estuvieron habitados entre 1-10 individuos y en más del 70% de los refugios existe un solo macho adulto escrotal. Las temperaturas dentro de los refugios tienden a ser más estables que en el exterior, pero no así la humedad relativa. La dieta, esta está compuesta por Insecta, Arachnida, con los coleópteros como los más frecuentes seguido por Lepidoptera y Hemiptera.

    Mamíferos de dosel en el Bosque Seco Chiquitano de Bolivia.
    (2026) Nicolas Malpartida Ferrero; Kathrin Barboza-Marquez; Luis H. Acosta Salvatierra
    Los estudios con cámaras trampa han aportado notablemente el entendimiento de la ecología de la mastofauna en el sotobosque, pero poco se sabe sobre las especies que habitan en el dosel. El Centro de Estudios del Bosque Seco Tropical “Alta Vista”, en Santa Cruz, Bolivia, alberga una parte representativa del Bosque Seco Chiquitano, donde se realizan estudios de flora y fauna local. Este trabajo buscó contribuir al conocimiento de la biodiversidad del dosel en este tipo de ecosistema. Se instalaron cámaras trampa a una altura de entre 4 y 20 m del suelo. Con un esfuerzo de 804 trampas/noche, se registraron ocho especies de mamíferos, destacando Glironia venusta y Sapajus apella. Los patrones de actividad mostraron una mayor actividad nocturna, lo que proporciona bases para futuras investigaciones sobre masto fauna del dosel.

    Nuevo registro de la carachupita de cola lanuda Glironia venusta Thomas, 1912, en el Bosque Seco Chiquitano de Bolivia
    (2024) Luis H. Acosta Salvatierra; Kathrin Barboza-Marquez; Nicolás X. Malpartida Fererro
    Este trabajo es el primer estudio exploratorio que se realiza en Bolivia para conocer la biodiversidad del dosel. Se instalaron 12 trampas cámara durante 67 días, entre los meses de enero y marzo del año 2023, en el Centro de Estudios del Bosque Seco Tropical Alta Vista. Se registró un total de 89 eventos de captura, de los cuales 50 pertenecieron a Glironia venusta, donde la frecuencia de captura fue 6,22 × 100 trampas/día. Los patrones de actividad registrados para G. venusta muestran cuatro picos de actividad. Adicionalmente, se propone la identificación de individuos a partir de las formas que dejan las líneas oscuras en el rostro.

    Taxonomic revision and additional comments of some bats (Mammalia, Chiroptera) reported from Bolivia, with an updated checklist based on voucher material with verified identities
    (Pensoft Publishers, 2023) José L. Poma-Urey; Luis H. Acosta S.; Kathia Rivero; Marisol Hidalgo-Cossio; Erika Hingst‐Zaher; Juliana Gualda-Barros; Beatriz Dybas da Natividade; Kathrin Barboza-Marquez; Héctor E. Ramírez-Cháves; Jorge Salazar‐Bravo
    We review the taxonomic identities of museum specimens of three bat species previously reported from Bolivia. We comment on some erroneously reported taxa, or taxa either not represented by voucher materials or based on insufficient data (including acoustic detections) to verify their taxonomic affinities. As result of this review, the list of bat species known to occur in Bolivia is updated to eight families and 133 species, unlike the nine families and 146 species of previous lists. Some recommendations for future research and a brief historical revision of bat inventories in the country are included.
