Species richness, diversity, structure, and distribution patterns across dominating forest communities of low and mid-hills in the Central Himalaya

Geology, Ecology, and Landscapes, 2022
The forests of the central Himalayan region are characterized by the dominance of some populous and conspicuous tree species across altitudes that are crucial for ecosystem functions and services. An understanding of such forests with relation to species

Drivers of vegetation and soil determine natural regeneration of a single plantation at different slope positions

Frontiers in Forests and Global Change, 2023
Promoting natural regeneration in artificial forest ecosystems is crucial for sustainable management. Understanding the fundamental mechanisms and drivers of tree regeneration is the prerequisite for promoting it effectively. This study worked with Larix

Rendimento de forragem e valor nutritivo de gramíneas anuais de estação fria submetidas a sombreamento por Pinus elliottii e ao sol pleno Forage yield and nutritive value of cool-season annual forage grasses shaded by Pinus elliottii trees and at full-sun

Revista Brasileira de Zootecnia, 2008
Avaliou-se o efeito do sombreamento provocado por duas densidades arbóreas em uma floresta de Pinus elliottii Engelm. com 10 anos de idade sobre o rendimento e o valor nutritivo da forragem de três gramíneas de ciclo hibernal.

Sap flow as a function of variables within nested scales: ordinary least squares vs. spatial regression models

Environmental Research: Ecology, 2023
Understanding scale-dependent influential drivers of sap flow variability can help managers and policymakers to allocate resources within a particular scale to improve forest health and resiliency against water-stress stimuli such as drought and insects,

Soil Fungal Community Characteristics at Timberlines of Sejila Mountain in Southeast Tibet, China

Journal of Fungi, 2023
Soil fungal community characteristics of alpine timberlines are unclear. In this study, soil fungal communities in five vegetation zones across timberlines on the south and north slopes of Sejila Mountain in Tibet, China were investigated.
