“…Bamboo species in the area include Dendrocalamus giganteus, Phyllostachys bambusoides, Bambusa pallida, Dendrocalamus hamiltonii, and Melocanna baccifera. Mehao WLS is also home to Mishmi teeta (Coptis teeta), an extremely valuable medicinal herb and threatened holoparasitic plant, Sapria himalayana (Ahmad et al, 2020). The sanctuary is warmer at lower altitudes and cooler at higher altitudes.…”

IntroductionTerrestrial mammals play a pivotal role in tropical forest ecosystems, representing a rich and functionally diverse component of these biomes. However, they confront formidable threats globally, such as hunting, habitat loss, and fragmentation, amidst the expansion of human-altered landscapes in tropical regions. Understanding the impacts of these changes on mammal communities is crucial for designing effective conservation interventions. Northeast India's tropical forests, a biodiversity hotspot, host a diverse array of mammalian fauna. The primary challenge faced by these species involves anthropogenic activities leading to the shrinkage and fragmentation of forested habitats.MethodologyIn this study, we conducted systematic camera trapping in Mehao Wildlife Sanctuary (WLS) to assess mammal status and distribution. Employing single-season occupancy models, we evaluated factors influencing mammalian species' detection probability and spatial utilization within the landscape. ResultsThe study documented 27 mammalian species, with 12 identified as "threatened" on the IUCN Red List. Species like clouded leopard, marbled cat, Gongshan muntjac, red goral, Mishmi takin, and sambar were recorded but observed infrequently. Notably, we reported the Asiatic brush-tailed porcupine's first sighting in Mehao. Our findings revealed that undisturbed forest habitats were preferred by all species. Mainland serow dominated most of the sanctuary's area, followed by northern red muntjac, yellow-throated marten, and masked palm civet.DiscussionThe response of mammalian species to ecological and anthropogenic covariates varied significantly, underscoring the necessity for species-specific management strategies alongside a landscape-scale conservation approach. These outcomes emphasize the urgency of managing and safeguarding rare and elusive mammalian species within and around Mehao WLS.

Sapria, a holoparasitic plant of Rafflesiaceae is still understudied in term of anatomical, even more in histoanatomical study. This study aimed to perform preliminary observation on Sapria himalayana Griff. f. albovinosa morphology on its early and late stage of flower bud development inside its host, Tetrastigma laoticum Gagnep. (Vitaceae). The results show the progression from the early flower bud as it starts to grow in the host vascular cambium area towards proximal direction to reach the host xylem and distal direction to reach the host phloem and to reach the next stage of the life cycle, into the late flower bud where differentiation occurs. In late flower bud, some primordial of the organs are visible as the flower bud grows larger distally towards the periderm. This development pattern is similar to the progression of development in the previous studies in Rafflesia and Rhizanthes, where endophytic growth was observable in both proximal (xylem area) and distal (peridermal). Future comparative study is encouraged, especially to compare between Sapria species and between different stages of growth. Although, an efficient method and less invasive way of sampling is encouraged to prevent decline of Sapria species in the wild.

New distribution record and DNA barcoding of Sapria himalayana Griff. (Rafflesiaceae), a rare and endangered holoparasitic plant from Mizoram, India

et al. 2022

Sapria himalayana Griff. is a rare and endangered holoparasitic plant that prefers a specific host (Tetrastigma sp.). It is one of the lesser-known and poorly understood plants facing threats of extinction owing to human interference in the evergreen forests of Mizoram. The flower is the only visible part of this endophyte and blooms from November to December. The plant was encountered for the first time in the evergreen forest near Rullam village in the Serchhip District of Mizoram, India. In the present study, DNA barcoding was used to identify the plants, and the internal transcribed spacer 2 (ITS2) region of S. himalayana was amplified and sequenced. The ITS2 sequence could accurately identify up to the species level for this endangered species. The absence of the ribulose-biphosphate carboxylase gene (rbcL) region in the genome supports its holoparasitic nature. Hence, DNA barcoding can help in taxonomic and biodiversity research and aid in selecting taxa for various molecular ecology and population genetics studies. The phylogenetic tree was analyzed using the maximum-likelihood method, and our findings showed that species from different families were clearly discriminated in a phylogenetic tree. To the best of our knowledge, this is the first report of DNA barcoding using ITS2 region of S. himalayana from Mizoram, India.
