Spatial patterns and associations of tree species at different developmental stages in a montane secondary temperate forest of northeastern China [PDF]

open access: yesPeerJ, 2021
Background Secondary forests have become the major forest type worldwide. Research on spatial patterns and associations of tree species at different developmental stages may be informative in understanding the structure and dynamic processes of secondary

Predicting Climate Change Impacts to the Canadian Boreal Forest

open access: yesDiversity, 2014
Climate change is expected to alter temperature, precipitation, and seasonality with potentially acute impacts on Canada’s boreal. In this research we predicted future spatial distributions of biodiversity in Canada’s boreal for 2020, 2050, and 2080 ...

Stomatal distribution pattern for 90 species in Loess Plateau – Based on replicated spatial analysis

open access: yesEcological Indicators, 2023
Stomata are the valves controlling carbon and water exchange between plant leaves and the atmosphere. Stomatal position changes throughout the whole growth of leaves, and the position is gradually fixed until the leaves mature, whether stomatal spatial ...

Changes and net ecosystem productivity of terrestrial ecosystems and their influencing factors in China from 2000 to 2019

open access: yesFrontiers in Plant Science, 2023
Changes in net ecosystem productivity (NEP) in terrestrial ecosystems in response to climate warming and land cover changes have been of great concern. In this study, we applied the normalized difference vegetation index (NDVI), average temperature, and ...

Super-Resolution Land Cover Pattern Prediction Using a Hopfield Neural Network [PDF]

open access: yes, 2002
Landscape pattern represents a key variable in management and understanding of the environment, as well as driving many environmental models. Remote sensing can be used to provide information on the spatial pattern of land cover features, but analysis ...

Algorithm for analyzing randomness in point patterns

open access: yesMethodsX
Various tests can be used to assess whether the spatial distribution pattern of a set of points is random, dispersed, or clustered. These tests typically compare the expected and observed distances among points, assuming no barriers.
