Mapping forest and site quality of planted Chinese fir forest using sentinel images [PDF]

Frontiers in Plant Science, 2022
Normally, forest quality (FQ) and site quality (SQ) play an important role in evaluating actual and potential forest productivity. Traditionally, these assessment indices (FQ and SQ) are mainly based on forest parameters extracted from ground measurement

Colorectal Cancer Anatomical Site and Sleep Quality [PDF]

Cancers, 2021
Purpose: Sleep quality in relation to anatomic site among colorectal cancer (CRC) patients is not well understood, though discerning the relationship could contribute to improved survivorship care. Methods: We ascertained sleep quality (Pittsburgh Sleep Quality Index) and other personal characteristics within an ongoing population-based study of CRC ...

Salinity reduces site quality and mangrove forest functions. From monitoring to understanding.

Science of the Total Environment, 2022
Mangroves continue to be threatened across their range by a mix of anthropogenic and climate change-related stress. Climate change-induced salinity is likely to alter the structure and functions of highly productive mangrove systems.

With Increasing Site Quality Asymmetric Competition and Mortality Reduces Scots Pine (Pinus Sylvestris L.) Stand Structuring Across Europe

Social Science Research Network, 2022
Heterogeneity of structure can increase mechanical stability, stress resistance and resilience, biodiversity and many other functions and services of forest stands. That is why many silvicultural measures aim at enhancing structural diversity.

Full-service hotels, convenience stores, or fire escapes? Evaluating the functional role of stopover sites for Neotropical migrants following passage across the Gulf of Mexico in autumn

Avian Conservation and Ecology, 2023
Nearctic Neotropical migratory songbirds incur the highest mortality during migration. En-route, songbirds rely on a network of stopover sites to rest, refuel, and/or seek refuge during poor weather. Conservation strategies prioritize protection of sites

Evaluation of the Site Form as a Site Productive Indicator in Temperate Uneven-Aged Multispecies Forests in Durango, Mexico

Plants, 2022
Even though the site index is a popular method for describing forest productivity, its use is limited in uneven-aged multispecies forests. Accordingly, the site form (SF) is an alternative measure of productivity to the site index based on the tree ...

Study of site quatity of Caucasian Alder (Alnus subcordala C. A. MeY.) in the Caspian Region (west of Mazandaran province) [PDF]

تحقیقات جنگل و صنوبر ایران, 2000
In order to determine the site quqlity on pure and even- age stands of alnus subcordata, 56 sample plots of 500 m² area were selected in different diameter (age) classes and all of trees were studied in sample plots.

Quantifying site quality in a heterogeneous landscape: recruitment of a reef fish.

Ecology, 2020
Heterogeneity in site quality can play an important role in patterns of abundance and population dynamics. Yet, estimating site quality in natural systems can be problematic because site quality can (1) vary through ontogeny for a focal organism, leading

Density and growth of forest stands revisited. Effect of the temporal scale of observation, site quality, and thinning

Forest Ecology and Management, 2020
Many current stand management guidelines propose low initial stand densities and strong density reductions in order to lower the costs of stand establishment, to accelerate stand growth and promote the diameter growth of selected future crop trees.
