Nutrient limitation in three lowland tropical forests in southern China receiving high nitrogen deposition: insights from fine root responses to nutrient additions.

open access: yesPLoS ONE, 2013
Elevated nitrogen (N) deposition to tropical forests may accelerate ecosystem phosphorus (P) limitation. This study examined responses of fine root biomass, nutrient concentrations, and acid phosphatase activity (APA) of bulk soil to five years of N and ...

In Site Soil Seed-Banks: Size, Composition and Persistence across Tropical Successional Stages

open access: yesPlants, 2023
I investigated the size, composition and persistence of the seed-bank in primary forests, secondary forests and old-fields in southern Mexico. I also assessed the contribution of the seed-bank to regeneration relative to other propagule sources.

Stand structure and history of an old-growth maple-beech forest

open access: yes, 2023
Ginn Woods is one of few old-growth forests in Indiana and a recently dedicated Indiana State Nature Preserve as of 2021. Previous research revealed old-growth characteristics such as a multi-layered tree canopy dominated by shade-tolerant species and an

Determination of Structural Characteristics of Old-Growth Forest in Ukraine Using Spaceborne LiDAR

open access: yesRemote Sensing, 2021
A forest’s structure changes as it progresses through developmental stages from establishment to old-growth forest. Therefore, the vertical structure of old-growth forests will differ from that of younger, managed forests.

Mature and old-growth forests contribute to large-scale conservation targets in the conterminous United States

open access: yes, 2022
Mature and old-growth forests (MOG) of the conterminous United States collectively support exceptional levels of biodiversity but have declined substantially from logging and development.

Managing old-growth forests for multiple ecosystem services [PDF]

open access: yes, 2020
Old-growth forest reserves offer the potential to facilitate the maintenance of multiple ecosystem services (ES), such as carbon storage, water and recreation, in managed landscapes.

Definition criteria determine the success of old-growth mapping

open access: yesEcological Indicators
Old-growth forests have been widely studied for decades. The extreme diversity of old forest characteristics has inspired an equally diverse set of old-growth definitions, and makes mapping old-growth difficult across large areas and different forest ...

Loss of deep roots limits biogenic agents of soil development that are only partially restored by decades of forest regeneration

open access: yesElementa: Science of the Anthropocene, 2018
Roots and associated microbes generate acid-forming CO2 and organic acids and accelerate mineral weathering deep within Earth’s critical zone (CZ). At the Calhoun CZ Observatory in the USA’s Southern Piedmont, we tested the hypothesis that deforestation ...

The human gut microbiome across the life course

open access: yesFEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.

Change in phylogenetic community structure during succession of traditionally managed tropical rainforest in southwest China. [PDF]

open access: yesPLoS ONE, 2013
Tropical rainforests in Southeast Asia are facing increasing and ever more intense human disturbance that often negatively affects biodiversity. The aim of this study was to determine how tree species phylogenetic diversity is affected by traditional ...
