Abstract
A number of plants species believed to be wind pollinated (anemophilous) are actually pollinated both by wind as well as insects (ambophily) because all the traits of the two pollination modes have not evolved simultaneously. Comparatively few angiosperms exhibit ambophily and the significance of such a mechanism is not fully understood. D...
Climate change is one of the significant factors influencing global species redistribution. As a result, a better understanding of the species' possible range change in future climate conditions is needed. Therefore, this study compiles global geographic occurrence data of a wild olive sub-species, Olea europaea subsp. cuspidate, and projected pote...
The Himalaya represents the most fragile ecosystem in the world, signifying its sensitivity towards global climate change. In the current scenario, the Himalaya needs to assess the climatic change trends at the regional level. To investigate climatic trends, we analysed the long-term (1980–2020) climatic data (maximum temperature—TMax and minimum t...
Olea ferruginea, a wild widely distributed species of the olive lineage, exhibits andromonoecy with protogynous perfect (hermaphrodite) and staminate (male) flowers. The present communication elucidates the differential performance of staminate and perfect flowers in reproductive assurance. The flowering chronology and function of perfect and stami...
Context
Reproductive success in dioecious plant species may be limited by severe pollen limitation owing to their separate sexes and pollination barriers.
Aims
Dodonaea viscosa subsp. angustifolia (Jacq.) (Sapindaceae) is a dioecious and wind-pollinated species that has a long flowering period. This study sought to determine the relationship betwe...
Oxidative stress, driven by reactive oxygen, nitrogen, and sulphur species (ROS, RNS, RSS), poses a significant threat to cellular integrity and human health. Generated during mitochondrial respiration, inflammation, UV exposure and pollution, these species damage cells and contribute to pathologies like cardiovascular issues, neurodegeneration, ca...
Conserving mountain species under climate change is a major ecological concern. It is still unclear how potential climate change will affect mountain plant species. The present study investigates the potential distribution of Himalayan Boxwood (B. wallichiana) under current and future climate scenarios using an ensemble modelling approach. The resu...
Olea ferruginea Royle is a wild Olive species commonly known as Indian or African Olive. In India, it is distributed in the Northwestern Himalaya, from Jammu and Kashmir to Uttarakhand, at an altitude of up to 2400 m amsl. The present study aims to determine the composition and community structure of Olea L. forests in Jammu and Kashmir, India. Dur...
Studies from different parts of the world have generated pieces of evidence of climate change’s effects on plant phenology as indicators of global climate change. However, datasets or pieces of evidence are lacking for the majority of regions and species, including for the climate-sensitive Himalayan biodiversity hotspot. Realizing this gap in info...
Elevational gradient, slope, and aspect offer a unique opportunity to explore the response of plant species under changing environmental conditions. The present study aimed to analyze the species diversity and distribution patterns with respect to altitude, aspect, and habitat types in the Kashmir Himalayas. Considering major aspects and habitats,...
Planning agricultural practises relies entirely on the timely prediction of rainfall based on data analysis. Early forecasting aids in the preparation of disaster management plans in high-risk locations in the event of predicted severe or limited rainfall. In this study, we analyzed the trends of precipitation and climatic variability for of Jammu...
In the era of anthropocene, global warming tends to alter the distribution range of the plant species. Highly fragile to such changes are the species that are endemic, inhabit higher elevations and show narrow distribution ranges. Predicting and plotting the appropriate suitable habitats and keeping knowledge of how climate change will affect futur...
The structure and distribution patterns of Himalayan vegetation are poorly explored, and research on species composition along the elevation gradient in these mountain ranges is still deficient. The current study was undertaken to analyze the variation and pattern of plant species composition along a vertical gradient in northwestern Himalaya, Indi...
In the changing climatic conditions, species distribution modelling is considered as a key strategy to estimate the probable influence of climatic variabilities on the habitat ranges of any species. The present study explores the potential distribution of Aconitum heterophyllum under current and future climatic scenarios. The results unfold that th...

Epigenetics are the heritable changes in gene expression patterns which occur without altering DNA sequence. These changes are reversible and do not change the sequence of the DNA but can alter the way in which the DNA sequences are read. Epigenetic modifications are induced by DNA methylation, histone modification, and RNA-mediated mechanisms whic...
An increase in atmospheric greenhouse gases necessitates the use of species distribution models (SDMs) in modeling suitable habitats and projecting the impact of climate change on the future range shifts of the species. The present study is based on the BIOMOD ensemble approach to map the currently suitable habitats and predict the impact of climat...
Study of reproductive biology and pollination ecology helps in understanding the life history patterns of species. Such a study brings to light the bottlenecks, if any, on account of which the individuals of the species are not able to reproduce in nature and ultimately helps in planning appropriate conservation strategies for the species under thr...
Vitex negundo (Lamiaceae), a highly important medicinal plant is widely distributed across tropical and subtropical regions of, Asia Africa and Australia. In the present investigation, studies on pollination biology and breeding system were carried out. The flowers are gamosepalous, gamopetalous, hermaphrodite and zygomorphic. Structurally the flow...
Valeriana wallichii DC. (Valerianaceae), a threatened medicinal plant of Himalayan region, has individuals showing 3 patterns of sex expression (female, hermaphrodite, and gynomonoecious). In the present study, the effect of floral size reduction on pollination efficiency of female flowers on female plants of Valeriana wallichii has been determined...
Valeriana wallichii, a perennial herb belonging to family Valerianaceae, is an important medicinal herb of the Himalayan region. The incessant exploitation of nature for meeting the demands of the pharmaceutical industry has put unbearable pressure on its natural habitats. A study on its physiological, biochemical, growth and reproductive attribute...
