A new, cyclic carbonate eudesmane-type sesquiterpene, eudesmacarbonate (1), was isolated from marine filamentous cyanobacterial mats associated with apparent ingestionrelated intoxications of captive bottlenose dolphins in the Florida Keys. Sequencing of 16S rDNA revealed that mats were composed of closely related Oscillatoriacean species including a previously undocumented species of Neolyngbya. The structure of 1 was elucidated by (+)-HRESIMS, 1D and 2D NMR, single-crystal X-ray diffraction, and vibrational circular dichroism data. Toxicity of 1 was assessed in the zebrafish embryo/larval model, and 1 was found to exhibit effects qualitatively similar to those observed for the known neurotoxin brevetoxin-2 and consistent with neurobehavioral impairment.

“…C. baccharoides is extremely endangered in this region, necessitating ongoing monitoring as well as conservation actions such as in situ restoration assisted by artificial introduction. (Pundir, 2015;Srivastava et al, 2016;Panwar et al, 2018;Tomar and Kumar, 2020). Tomar and Kumar (2020) collected explants from Mohand (Saharanpur) and near Mansa Devi, RajaJi National Park, (Haridwar) and rooting was 57.5 % after 84 days of planting and 6000 ppm IBA exogenous treatment which was better than the result obtained by Srivastava et al (2017) who found rooting of cuttings was 25 -30 % after 60 days.…”

For conservation status, earlier exploration or survey reports especially of Uttarakhand and Uttar Pradesh were used for comparison (Pundir, 2015;Srivastava et al, 2016: Chandra et al, 2017.

“…Catamixis baccharoides Thomson a monotypic genus belongs to family Asteraceae, commonly known as 'Vishpatri' is also facing similar threat. It is critically endangered and habitat-specific shrub, endemic to forests of Central and North-West Himalaya in Sivalik hills (IUCN, 2014;Pundir, 2015;Srivastava et al, 2016), which is an extension of the outer Himalayas and is formed of conglomerate and sandstone rocks (Chisholm, 1911).…”

Aim: The aim of the study is to provide current conservation status of IUCN listed critically endangered species, Catamixis baccharoides, and to study the population density of species in three major locations: Biyasi, Rajaji National Park near Mansa devi in Uttarakhand and Mohand in Uttar Pradesh. Methodology: Two concurrent field surveys during April - May 2018 and March - May 2021, were conducted for population study of Catamixis baccharoides. Belt transect method was used for biomass evaluation of species at all three locations and sampling were done using transect path of 1000 m (20 m wide). Plants habit, morphology and phenology were described on the basis of field observation. Population density of the species in sample survey was determined and seeds were collected for germination test. Results: The population of plant in first survey 2018 was compared with 2021 survey and other previous survey conducted by other authors, and observed that there was sudden decease in plant density from 11 plants to zero in Biyasi location and the population was steady in Mohand (6 plants) and Mansa Devi (24 plants) Rajaji National Park Haridwar. Seeds seem to be recalcitrant in nature. Interpretation: Catamixis baccharoides, also known as “Vish-Patri”, an endemic monotypic shrub of Asteraceae family and is categorized in critically endangered category under IUCN. The population of this species is declining at an alarming rate from its natural habitat in Uttarakhand and Uttar Pradesh. In Biyasi location Uttarakhand, the population of species had vanished due to anthropogenic disturbances and ignorance during Char Dham road project and is decreasing rapidly in other locations. However, the medicinal and economical vantage of C. baccharoides is yet unexplored so, there is a need to take necessary steps to conserve the species in its natural habitat. Key words: Belt transect method, Conservation, Critically endangered, Monotypic
