Seasonal variations in carbon, nitrogen, and phosphorus of Pinus yunnanenis at different stand ages

Frontiers in Plant Science, 2023
The seasonal variations in carbon (C), nitrogen (N), and phosphorus (P) at the organ level of Pinus yunnanenis during different season are poorly understood. In this study, the C, N, P, and their stoichiometric ratios in various organs of P.

Three scenarios for tree species composition and stand age in new and permanent forest areas: A case study of Latvia

, 2023
Land abandonment and the emergence of new forest areas create novel dynamics for forest ecosystems and landscapes. Modelling is often used to forecast tree species composition, age group distribution and spatial patterns in the future.

Impaired Postural Control Reduces Sit-to-Stand-to-Sit Performance in Individuals with Chronic Obstructive Pulmonary Disease [PDF]

, 2014
Background: Functional activities, such as the sit-to-stand-to-sit (STSTS) task, are often impaired in individuals with chronic obstructive pulmonary disease (COPD).

Phosphorus dynamics in litter–soil systems during litter decomposition in larch plantations across the chronosequence

Frontiers in Plant Science, 2022
The dynamics of phosphorus (P) in litter–soil systems during litter decomposition across a plantation chronosequence remain to be underinvestigated, especially in terms of the nutrient cycle in plantations.

Transforming even-aged coniferous stands to multi-aged stands: an opportunity to increase tree species diversity? [PDF]

Forestry: An International Journal of Forest Research, 2020
Abstract Transforming even-aged coniferous stands into multi-aged ones is attracting growing interest in Europe. However, applying this silvicultural treatment, maintaining a continuous cover and relying on natural regeneration require a deep understanding of the factors driving interspecific competition in the understorey. In particular,

Bare Land Referenced Algorithm from Hyper-Temporal Data (BRAH) for Land Use and Land Cover Age Estimation

Land, 2023
Determining the age of land use and land cover (LULC) using satellite imagery has long been one of the challenging tasks in remote sensing research. Accurately determining age, especially crop age, is essential for plot management, biomass calculations ...

Standing as Channeling in the Administrative Age

SSRN Electronic Journal, 2012
For several decades, courts have approached citizen suits with judicially created rules for standing. These requirements for standing have been vague and unworkable, and often serve merely as a screening mechanism for docket management. The use of standing rules to screen cases, in turn, yields inconsistent decisions and tribunal splits along partisan ...

Breast cancer and aging: Standing on the shoulders of a giant

Journal of Geriatric Oncology, 2020
With the aging of the US population, the number of individuals age 65 or older who will be diagnosed with breast cancer is expected to rise. Despite this, older adults with breast cancer remain severely under-represented in cancer clinical trials. Numerous studies have highlighted disparites in care experienced by older patients with breast cancer. Dr.

Fine root biomass and production in Scots pine stands in relation to stand age [PDF]

Tree Physiology, 2001
We determined fine root biomass and production of 15-, 35- and 100-year-old Scots pine (Pinus sylvestris L.) stands during three growing seasons. Fine roots were sampled by the soil core method. Mean (+/- SE) annual fine root biomass of Scots pine in the 15-, 35- and 100-year-old stands was 220 +/- 25, 357 +/- 21 and 259 +/- 26 g m(-2), respectively ...
