TL;DR: In this paper , a study was conducted to understand the plant diversity of Prashar alpine pasture, District Mandi, Himachal Pradesh during the year 2017 between 2550-2750 m elevation ranges.
Abstract: Abstract Seasonal fluctuation in the plant diversity provide basis for devising suitable strategies for management and conservation of the plant resources. Accordingly, a study was conducted to understand the plant diversity of Prashar alpine pasture, District Mandi, Himachal Pradesh during the year 2017 between 2550–2750 m elevation ranges. The study was carried out on seasonal basis. The study was carried out in summer season in May, rainy season in August and winter season in November. A total of 44 plant species belonging to 24 families and 35 genera were recorded in summer season, a total of 72 plant species belonging to 28 families and 58 genera were recorded in rainy season and a total of 13 plant species belonging to 6 families and 10 genera were recorded in winter season from the study area. Dominant families were Asteraceae, Lamiaceae, Rosaceae, Poaceae and Polygonaceae. A total of 56 medicinal plant species recorded from the pasture, out of which two species viz; Roscoea alpina and Selinum vaginatum fall in the category of threatened plants.

TL;DR: In this article , the main life processes of boreal trees are discussed and the variability of functional traits of flowering and seed production, xylem conductivity, bud and cambium phenology, as well as transpiration and photosynthesis, as a consequence of the interaction of genotype and environment.
Abstract: Abstract Species continuity under the harsh climatic conditions of the boreal forest requires trees to ensure the functioning of two main life processes, namely growth and reproduction. However, species survival becomes a challenge when environmental conditions become unstable and reach the taxa’s ecological tolerance limit. Survival in an unstable environment is possible through the concurring processes of phenotypic plasticity and local adaptation; each process has its advantages and shortcomings. Local adaptation allows attaining the best possible fitness under conditions of limited gene flow and strong directional selection, leading to specific adaptations to the local environment; however, there is a risk of maladaptation when conditions suddenly change. In turn, phenotypic plasticity provides trees an advantage when weather events change rapidly and enables a response expressed by the production of different phenotypes by the same genotype. However, this process is expensive in terms of costs in maintenance and causes developmental instability within the individual. Boreal trees utilize both processes as reflected in variations in their functional traits within the same species. In this chapter, we address the main life processes, presenting the variability of functional traits of flowering and seed production, xylem conductivity, bud and cambium phenology, as well as transpiration and photosynthesis, as a consequence of the interaction of genotype and environment. We describe the practical consequences of a variation in functional traits, as expressed in chemical and mechanical wood properties. Finally, we outline applications and perspectives for managing boreal forests in a context of heterogeneous and changing environmental conditions.
