A study on plant preferences of red panda (Ailurus fulgens) in the wild habitat: foundation for the conservation of the species

The red panda is a lesser carnivore that has adapted to the herbivore diet and is distributed in the Himalayan and Hengduan mountain ranges. The study conducted on red panda in Singalila National Park recorded the highest encounter of the species within the altitude of 2800 to 3200 meters in the broad leaf deciduous and broad leaf coniferous forest. 22.22% of direct sightings of red pandas occurred on plant species belonging to the family Fagaceae and were followed by the family Ericaceae (18.52%). The plant species mostly preferred by the red panda in Singalila National Park were Lithocarpus pachyphyllus, Rhododendron arboreum, Abies densa, and Betulia utilis. During all seasons, the dominant plants found in the red panda pellets were Arundinaria maling and Arundinaria aristata.  The distribution of the red panda is influenced by the presence of the preferred plant species, therefore, through this studies effort has been made to document the plant species used by the red panda in the wild habitat.

Successful rescue, medical management, rehabilitation, and translocation of a Red Panda Ailurus fulgens (Mammalia: Carnivora: Ailuridae) in Arunachal Pradesh, India

We document the rescue of a Red Panda from Yachuli circle, Lower Subansiri district and successful translocation to Eaglenest Wildlife Sanctuary, West Kameng district of Arunachal Pradesh, India. The head injury was surgically managed under the anaesthetic combination of ketamine and xylazine, and reversed with yohimbine. The animal was successfully rehabilitated and translocated in the Eaglenest Wildlife Sanctuary.

The tongue of the red panda (Ailurus fulgens fulgens Cuvier, 1825)—a stereoscopy, light microscopy and ultrastructural analysis

In the light of recent molecular studies, there are two phylogenetic species of the red panda (Ailurus fulgens): Ailurus fulgens fulgens and Ailurus fulgens styani. The red panda belongs to the endangered species living in the wild only in Asia and is included in the CITES list. Although the biology and diet of this species has been extensively described, the histological structure of the tongue and lingual glands has not yet been characterized in detail in relation to the lifestyle of this mammal under specific conditions and as a basis for comparative anatomical studies of the biodiversity of endemic species. Study samples were collected from two adult males of Ailurus fulgens f. held in Wrocław Zoological Garden. Both tongues were examined macroscopically; moreover, samples with lingual papillae for light microscopy and scanning electron microscopy (SEM) were collected from the apex, body and root of the tongue. Both tongues of the Ailurus fulgens f. males were approximately 9 cm long. The dorsal lingual surface was covered with mechanical and gustatory lingual papillae. Filiform papillae were observed on the apex and the body of the tongue, while small conical papillae were observed on the root of the tongue. An elongated, 1–1.5 cm long cylinder-shaped lyssa was observed in the ventral part of the apex. Moreover, most numerous and largest round in shape fungiform papillae were observed on the apex and on the border of the body and root of the tongue, located directly rostrally to 12–13 round and oval in shape vallate papillae. The SEM study showed that filiform papillae on the apex had several long secondary processes, while filiform papillae on the body of the tongue were taller and their secondary papillae were shorter than the equivalent structures on the apex of the tongue. The SEM study showed numerous taste pores on the surface of the fungiform papilla, while irregular surface of the vallate papillae, however some of them had smoother surface. Mixed glands (comprised of mucous acini and serous acini) were present within the vallum (within the connective tissue core) of the vallate papilla. Beneath the papillae more serous glands were observed, while the posterior lingual glands in the caudal part of the root of the tongue were mucoserous (mucous units were prevalent). A characteristic feature of the tongue of Ailurus fulgens f. was the presence of lyssa, which is comparable to other representatives of Carnivora, but the number of vallate papillae was individually variable. The lack of strongly developed mechanical conical papillae probably may be related to the type of plant food that is particularly dominant in red panda. Further differences between Ailurus fulgens f. and Ailurus fulgens s. cannot be excluded. The results of these studies may be useful especially for veterinarians specializing in working with exotic animals and people dealing with wildlife conservation.

Incidence of pregnancy loss and characterization of fetal development in red pandas

Previous reports indicate that red pandas (Ailurus fulgens styani) may experience fetal loss during gestation; however, neither the rate nor timing of pregnancy failure has been described in this species. The objective of the current study was to utilize ultrasound video and images collected between 2010-2020 at the Cincinnati Zoo and Botanical Garden to better characterize pregnancy loss and fetal development. Trans-abdominal ultrasound examinations were performed on six female red pandas over a 10-year period, resulting in 12 profiles. Pregnancy was diagnosed via ultrasound in all profiles in which cubs were produced (n = 8) and in two profiles in which cubs were not produced. Two additional females did not produce cubs and no concepti were discernible via ultrasound. Fetal loss was documented in 40.0% of pregnancies and was classified into Lost (2 of 10; 20.0%), in which no cubs were produced, or Partial Loss (2 of 10; 20.0%), in which two concepti were visualized via ultrasound, but only one cub was born. Fetal loss occurred between days 51 and 23 pre-partum. Fetal growth characteristics were documented, including skeletal ossification (occurring between day 32 and 27 pre-partum), crown-rump length, head length, cranial length, and fetal heart rate (173-206 beats per minute). These findings provide novel insights into pregnancy loss, may serve as a reference for milestones of fetal development, and may be useful in diagnosing pregnancy and assessing pregnancy loss in red pandas.

The first painting of the red panda (Ailurus fulgens) in Europe? Natural history and artistic patronage in early nineteenth-century India

Throughout the late eighteenth and early nineteenth centuries, British East India Company officials, based in the Indian subcontinent, amassed huge collections of natural history images. One of the largest collections, consisting of many thousands of individual paintings commissioned mainly from Indian artists between 1790 and 1823, was formed by Major-General Thomas Hardwicke. Some of these later formed the basis of John Edward Gray’s Illustrations of Indian zoology, but the vast majority remained unpublished. This paper focuses on one of these images, a detailed watercolour of the red panda ( Ailurus fulgens), painted to accompany a scientific description of the species which Hardwicke sent from Bengal to the Linnean Society of London in 1820. The painting pre-dates Frédéric Cuvier’s description of the animal by four years, and is almost certainly the first image of the red panda to have arrived in Europe. This paper sets the painting in the context of Hardwicke’s career as a naturalist and private patron of Indian artists, highlighting both his role as an early investigator of Indian zoology and the importance of “Company Art” in the accrual of scientific information.

Red Panda feces from Eastern Himalaya as a modern analogue for palaeodietary and palaeoecological analyses

Modern feces samples of the endangered red panda (Ailurus fulgens) were examined using multiproxy analysis to characterize the dietary patterns in their natural habitat in India. An abundance of Bambusoideae phytoliths and leaves (macrobotanical remains) provide direct evidence of their primary dietary plants. In contrast, Bambusoideae pollen is sporadic or absent in the pollen assemblages. An abundance of Lepisorus spores and its leaves along with broadleaved taxa, Betula, Engelhardtia, and Quercus are indicative of other important food sources. Average δ13C values (− 29.6‰) of the red panda feces indicate typical C3 type of plants as the primary food source, while the, δ15N values vary in narrow range (3.3–5.1‰) but conspicuously reveal a seasonal difference in values most likely due to differing metabolic activities in summer and winter. The multiproxy data can provide a baseline for the reconstruction of the palaeodietary and palaeoecology of extinct herbivores at both regional and global scales.

Photographic evidence of Red Panda Ailurus fulgens Cuvier, 1825 from West Kameng and Shi-Yomi districts of Arunachal Pradesh, India

Camera-trap photos of Red Panda Ailurus fulgens were obtained from three locations in the state of Arunachal Pradesh in northeastern India during a survey conducted from March to July 2019. Two of the locations are in West Kameng district and one location is in Shi-Yomi district (formerly West Siang). These records are important additions to the currently limited information available for species distribution in the state, and was gathered as part of a tri-country study on the status of tiger habitats in high altitude ecosystems of Bhutan, India, and Nepal.

Potential effects of GPS collars on the behaviour of two red pandas (Ailurus fulgens) in Rotterdam Zoo

GPS collars are frequently used to study the (behavioural) ecology of species. However, such collars can cause behavioural changes and can have negative physiological effects on the individuals wearing them. A pilot study to obtain data on behavioural and physiological effects of GPS collars on the target species would therefore be recommended, especially when it concerns rare or endangered species. The red panda (Ailurus fulgens) is a small carnivore endemic to the mountains of Central Asia that is currently classified as endangered. There is a lack in knowledge on the species ecology which could be enhanced by a study using GPS-technology. As a pilot study, the two adult red pandas in Rotterdam Zoo were observed before and after fitting a GPS-collar, to determine possible behavioural effects of wearing a collar. Although the study did not take place under ideal circumstances, indications of both behavioural, e.g. increased shaking behaviour, and physical, e.g. abrasions, effects of the collar were found. Even though our results were only based on two individuals, our findings stress the need for pilot studies in controlled environments before GPS collars to ensure safety of the study species and validity of the collected data.
