AI Article Synopsis
- The study highlights the lack of research on a specific genus from Asia, revealing that only one species was previously recorded in Pakistan.
- Two new species have been discovered in the Himalayan oak forests of Pakistan, each with unique morphological features.
- Phylogenetic analysis of DNA sequences supports the classification of these two taxa as new species, confirming their distinct characteristics through both macro- and micromorphological descriptions.
Article Abstract
The genus is poorly studied from Asia. From Pakistan, only one species has been reported so far. Two new species in the genus have been collected from Himalayan oak forests of Pakistan. (section Pudorini, subgenus Colorati) is characterised by its pure white, centrally depressed pileus, occurrence of white stipe with yellow patches at lower half and broader (4.98 μm) basidiospores. (section Hygrophorus, subgenus Hygrophorus) is characterised by its yellowish-green stipe with white apex that has fine scales on the entire stipe, an off-white pileus with dark green and greyish fibrils, ovoid to ellipsoid basidiospores and clavate 4-spored basidia. Macro- and micromorphological descriptions have revealed that both these taxa are not yet described. Phylogenetic estimation based on DNA sequences from the internal transcribed spacer (ITS) region and large subunit (LSU) of the nuclear ribosomal DNA (rDNA) genes, is congruent with the morphological characters that help to delimit these as new species of . Allied taxa are also compared.

Shifts in the ecological drivers influence the response of tree and soil carbon dynamics in central Himalayan forests.

Understanding and regulating global carbon relies crucially on comprehending the components and services of forest ecosystems. In particular, interactions that govern carbon storage in trees, soil, and microbes, driven by factors like vegetation structure, function, and soil characteristics, remain poorly understood, especially in the central Himalayas. To address this gap, we investigated carbon storage in tree aboveground biomass, root biomass, and soil across different vegetation types.

- Researchers studied strokes from 1990 to 2021 to understand how many people get them and how they are affected around the world.
- In 2021, strokes caused about 7.3 million deaths and were a major cause of health problems, especially in specific regions like Southeast Asia and Oceania.
- There are differences in stroke risks based on where people live and their age, and some areas actually saw more strokes happening since 2015.

The present study investigates the seasonal variations in leaf ecophysiological traits and strategies employed by co-occurring evergreen and deciduous tree species within a white oak forest (Quercus leucotrichophora A. Camus) ecosystem in the central Himalaya. Seasonal variations in physiological, morphological, and chemical traits were observed from leaf initiation until senescence in co-occurring deciduous and evergreen tree species.

Plant invasion is a leading threat to biodiversity, ecosystem services and human wellbeing worldwide. In the central Himalayas intentionally or accidentally introduced invasive alien plant species (IAPS) facilitate their own establishment and spread, which is altering forest structure, vegetation composition, species diversity and livelihood. To understand the perception and awareness amongst local communities about invasive alien and native plants and its effect on local livelihood, a questionnaire-based study was conducted in 10 villages of Nainital district, Uttarakhand, India.
