Placentophagia is a natural behaviour in mammals. Although placentophagia has been reported from 18 species of bats so far, the instance from the wild are infrequent. Rousettus leschenaultii is a widely distributed species across South and Southeast Asia, and is consistently described as a common species throughout its range. However, the ecology of this species is poorly known according to the latest IUCN assessment. Through this note, we provide the first recorded instance of placentophagia and birth-associated behaviours of this species in the wild.

The Complejo Volcánico Doña Juana – Cascabel National Natural Park is located between the departments of Cauca and Nariño in the southern Andean Region of Colombia. Due to the country’s social challenges and the difficult access to the Doña Juana – Cascabel National Natural Park the biological knowledge concerning groups such as mammals, is based on studies prior to the park’s declaration, reports from park rangers and residents. Between October 2017 and February 2018, eight trail cameras were set up in the Doña Juana – Cascabel National Natural Park and its buffer zone. We reviewed the information captured in these cameras and identified eight mammal species, three of which are new reports for the park. In total, 24 species were reported, including charismatic Andean species such as the spectacled bear (Tremarctos ornatus), and the Andean tapir (Tapirus pinchaque). The mammal diversity documented for the park is low (24 species) compared to other Andean areas. Further field work is necessary to complete the species inventories. Nevertheless, this research, to our knowledge is the first effort to study the medium and large mammals of the Doña Juana – Cascabel National Natural Park since its establishment in 2008.

The Andean swamp rat Neotomys ebriosus is a sigmodontine rodent restricted to the Central Andes of South America. A distribution map of the species in Peru have been previously drawn based on few of the localities where the species has been captured and collected. I update the distribution of the species in Peru based on new records from three different areas surveyed by the author, specimens at Museum collections in the United States and France from VertNet webpage, localities from the collection at the Natural History Museum of Universidad Nacional Mayor de San Marcos, and localities from the collection at the Natural History Museum of the Universidad Nacional San Agustín. The northern limit of the species distribution is increased based on new localities with collected individuals. Habitat used by N. ebriosus is mainly high Andean bogs; most individuals caught adjacent to the borders of Andean bogs and along streams near the bogs. Collected individuals leave unclear subspecies division and identity.

New records are provided for two species of bat from Argentina belonging to the family Vespertilionidae, Histiotus montanus and the recently described Neoeptesicus ulapesensis. These data extend the range of both species incorporating them into two new provinces. One record comes from the revision of a specimen deposited in the Colección Mamíferos Lillo for more than six decades, highlighting the importance of biological collections for studying the systematics and distribution of species.

Arboreal camera traps are becoming more commonly used for monitoring wildlife. Pangolins (Order: Pholidota) are a threatened group of mammals that are challenging to monitor across their range. In this study, we assessed the use of arboreal and ground camera traps for monitoring the three pangolin species native to West Africa in the Ziama Man and Biosphere Reserve, Guinea. We fit occupancy models to our data to examine the effect of factors related to camera height and tree height on detection probability. In addition, we evaluated the utility of deploying multiple cameras within the same tree. Our study showed that arboreal camera traps can successfully detect both arboreal pangolin species, with the highest detection in mid-canopy for white-bellied pangolin and mid-to high-canopy for black-bellied pangolins. In addition, our results suggest at least 4–6 cameras deployed on each tree to maximize the opportunity of detecting these species. We did not detect giant pangolins. Further studies are needed to continue improving detection of all three pangolins for monitoring and adaptive management of these heavily harvested and traded species.

Thomas’s Flying Squirrel (Aeromys thomasi) is a rarely observed, large, nocturnal species of Flying Squirrel, confined to the island of Borneo. Very little is known about the ecology, behaviour, and natural history of the species. Fruit is the only diet item recorded so far. I report for the first time feeding on bark and on young leaf shoots by the species. These observations match the results of an examination of the species’ dentition, which had suggested a mixed diet including leaves.

Unusual colorations are rare in Didelphis, but records are important to understand genetic aspects of the species. Albino individuals have a total absence of pigmentation throughout the body (skin and hair) and have eyes without traces of pigmentation, but with a red or pink color. We draw attention to the first two confirmed records of albinism in white-eared opossum (Didelphis albiventris) and their karyotype. This is the first record of albinism in D. albiventris in Northeastern Brazil. This calls attention to develop future research on the genetic diversity and the risk of inbreeding and consanguinity in populations of this region.

Knowledge of reproduction in wild Andean bears (Tremarctos ornatus) is scarce. Here we provide novel information about litter size, birth timings, courtship and multi-generational groups in a population in the Chingaza massif in Colombia. Pregnant females, mothers with cubs, estimated birth times, and litter size were registered through camera trapping of a population at the Chingaza massif (Colombia) between 2011 and 2016. A total of 34 independent records of reproductive female bears were obtained. Twenty-eight (28) different reproductive females were recognized by external key features. Six different females were recorded only pregnant, two others were recorded pregnant and later with cubs, and 20 others were recorded only with cubs. In total, 29 cubs were recorded in 22 litters, with a mean litter size of 1.27 (SD = 0.45): 16 litters with one cub, 5 with 2 cubs, and 1 with 2 cubs + a big cub from a previous litter (>1 year). The highest records of mothers with little cubs were obtained for the low rain season in December, January, and February, full of dry-season-fruiting Ericaceae shrubs. Likewise, the highest estimated births were obtained during the rainy time in June. Multi-generational groups and the courtship behaviors are reported for the first time in Colombia.

The Brazilian Atlantic Forest has undergone significant transformation, resulting in habitat loss and the endangerment of many species of mammals and other vertebrates. In this study, the presence of fluctuating asymmetry of four anatomical structures of the arboreal rodent Rhipidomys mastacalis was evaluated using geometric morphometrics. The study focused on adult specimens collected in a mosaic of vegetation composed of forested vegetation, occupancy mosaics in forested areas, and cocoa plantations. The results showed significant values of fluctuating asymmetries in all structures and in all areas. The skulls and scapulae showed the highest values of asymmetry in forested vegetation and cocoa plantations, while the mandibles showed the greatest values in forested vegetation, and the pelvis in occupancy mosaics and cocoa plantations. These findings are consistent with previous studies that have evaluated developmental stability in mammals and suggest that high asymmetry values indicate an effect on different phases of ontogeny, which can harm the survival of a species in future generations. Overall, this study provides important insights into the impacts of habitat fragmentation on Rhipidomys mastacalis and highlights the need for conservation efforts to preserve the integrity of the Brazilian Atlantic Forest and its diverse range of wildlife.

Abstract Morphological abnormalities in bats are rarely reported and, particularly, ocular problems are relatively scarce in the literature. We present a review of the records of ocular alterations in bats of the American continent and document for the first time a case of ocular alteration in the species Saccopteryx bilineata in northern Colombia. In this study we found cases of corneal opacity (5/19 individuals), lesions and trauma, microphthalmia (4/19 individuals), anophthalmia (4/19 individuals) and adnexal diseases (2/19 individuals). We encourage researchers to report their observations of bats with ocular anomalies, as this information could be useful for estimating occurrence rates and addressing questions associated with the social behaviour of the species and on their effects on natural populations.
