Critically Endangered Species

Jerdon's baza Aviceda jerdoni is one of the least studied raptor species in Nepal which is listed as a Critically Endangered species in the ‘Nepal's Red List of Birds’. This paper presents the records of this species during opportunistic surveys, conducted in 2018/2019 from Ilam and Jhapa districts of eastern Nepal. A total of 18 individuals were sighted during the study period with the first record of nest of the species in Nepal. The sightings were made between 70 m, the lowest global known range to 1048 m from mean sea level, and the highest altitudinal record for Nepal. Hunting and unintentional prey poisoning were identified as major threats for species in the study site.

Three species of chewing lice—Eucolpocephalum femorale (Piaget, 1880) (Amblycera: Menoponidae), Ibidoecus plataleae (Denny, 1842) (Ischnocera: Philopteridae) and Ardeicola plataleae (Linnaeus, 1758) (Ischnocera: Philopteridae)—are reported from the black-faced spoonbill (Platalea minor Temminck & Schlegel, 1849) in Japan. These three louse species are new records for this host. The black-faced spoonbill is classified as a “Critically Endangered” species in the IUCN Red List; although its species of lice are known to infest other species of spoonbills, these lice are endangered at the population level.

Apical Pore

Eugenia alletiana, a new endemic species from Mauritius, is described and its ecology and conservation is discussed. The morphological diagnostic features for Eugenia alletiana are chartaceous, discoloured leaves, very thin terminal branchlets, flowers solitary or in fascicles of 2–3 flowers, totally fused hypanthium without apical pore or calyptra, that encloses the numerous stamens (> 500) and petals before anthesis; seed enclosed in a woody endocarp with a lamellated outer surface. The species should be considered as Critically Endangered (CR) according to the Red List Criteria of the International Union for the Conservation of Nature. This assessment is based on the plant’s restricted distribution, very small population size, a habitat sustaining degradation by invasive alien plants and animals and predation of immature fruits and seeds by invasive alien monkeys and rats respectively leading to a weak regeneration.

Flower Visiting

In the present paper we provide the first contribution to the knowledge of the flower-visiting insect assemblages of the alpine plant species Callianthemum kernerianum Freyn ex A. Kerner (Ranunculaceae). This focal plant species was selected since it is a steno-endemic and critically endangered species belonging to the IUCN red-list. Fifteen taxa were recorded, among which very few are true pollinators, whereas all the others can be considered only indirect pollinators. The peculiar phenology of the plant and the harsh habitat conditions in which it grows probably affect the richness and abundance of flower-visiting insects as well as of true pollinators. This could be the reason for this plant to be a self-compatible species.

Melanophryniscus admirabilis (admirable red-belly toad) is a microendemic and critically endangered species found exclusively along 700 m of the Forqueta River, in a fragment of the Atlantic Forest of southern Brazil. One of the greatest concerns regarding the conservation of this species is the extensive use of pesticides in areas surrounding their natural habitat. In recent years, the adaptation and persistence of animal species in human-impacted environments have been associated with microbiota. Therefore, the present study aimed to characterize the oral bacterial community of wild M. admirabilis and to address the question of how this community might contribute to this toad’s adaptation in the anthropogenic environment as well as its general metabolic capabilities. A total of 11 oral samples collected from wild M. admirabilis were characterized and analyzed via high-throughput sequencing. Fragments of the 16S rRNA variable region 4 (V4) were amplified, and sequencing was conducted using an Ion Personal Genome Machine (PGM) System with 316 chips. A total of 181,350 sequences were obtained, resulting in 16 phyla, 34 classes, 39 orders, and 77 families. Proteobacteria dominated (53%) the oral microbiota of toads, followed by Firmicutes (18%), Bacteroidetes (17%), and Actinobacteria (5%). No significant differences in microbial community profile from among the samples were reported, which suggests that the low dietary diversity observed in this population may directly influence the bacterial composition. Inferences of microbiome function were performed using PICRUSt2 software. Important pathways (e.g., xenobiotic degradation pathways for pesticides and aromatic phenolic compounds) were detected, which suggests that the bacterial communities may serve important roles in M. admirabilis health and survival in the anthropogenic environment. Overall, our results have important implications for the conservation and management of this microendemic and critically endangered species.

With its unique square-shaped culm, Chimonobambusa hirtinoda C.S. Chao & K.M. Lan is a critically endangered species, and its natural habitat is solely restricted to Doupeng Mountain in Guizhou, China. Two small-insert libraries from C. hirtinoda were constructed and sequenced. Approximately 127.83 Gb of highquality reads were generated and assembled into 9,320,997 contigs with a N50 length of 213bp, thereby producing 8,867,344 scaffolds with total length of 2.01 Gb. An estimated genome size of C. hirtinode was 2.86 Gb on the basis of k-mer frequency analysis, with the GC content of 45.40%. The repeat rate and heterozygous ratio were 74.11 and 1.48% in C. hirtinoda genome, respectively. Finally, 65,398 SSR loci were identified in the assembled contigs, including 58.66% tri-nucleotide, 27.42% di-nucleotide, 7.94% tetranucleotide, 3.67% penta-nucleotide, and 2.31% hexa-nucleotide. Results of this study are useful not only for ecological conservation of C. hirtinoda, but also for phylogenetic studies.
