An improved area-based approach for estimating plot-level tree DBH from airborne LiDAR data被引量：2
《Forest Ecosystems》2023年第1期46-55,共10页Zhengnan Zhang Tiejun Wang Andrew K.Skidmore Fuliang Cao Guanghui She Lin Cao 
funded by the National Key Research and Development Program(No.2017YFD0600904);the National Natural Science Foundation of China(No.31922055);the Postgraduate Research&Practice Innovation Program of Jiangsu Province(No.KYCX21_0913);the Priority Academic Program Development of Jiangsu Higher Education Institutions(PAPD);funded by the China Scholarship Council(Grant No.202108320285);partially supported by the Horizon 2020 Research and Innovation Programme—European Commission‘BIOSPACE Monitoring Biodiversity from Space’project(Grant Agreement ID 834709,H2020-EU.1.1)。
The diameter at breast height(DBH) of trees and stands is not only a widely used plant functional trait in ecology and biodiversity but also one of the most fundamental measurements in managing forests. However, syste...

Expected adult lifespan in tropical trees: Long-term matrix demography in a large plot
《Forest Ecosystems》2022年第4期558-566,共9页Richard Condit 
Numerous grants from National Science Foundation (US), the Smithsonian Institution, the Mac Arthur Foundation, and Earthwatch supported census work in the Barro Colorado 50-ha plot;The Center for Forest Science at the Morton Arboretum provided support for the author while writing
Background: Documenting the entire lifetime of long-lived organisms requires splicing together short-term observations. Matrix demography provides a tool to calculate lifetime statistics, but large samples from juveni...

Soil carbon and nutrient stocks under Scots pine plantations in comparison to European beech forests: a paired-plot study across forests with different management history and precipitation regimes
《Forest Ecosystems》2021年第3期628-643,共16页Marco Diers Robert Weigel Heike Culmsee Christoph Leuschner 
funded by the Federal Ministry for Education and Research(BMBF)through a grant to CL(project number:01LC1314B).
Background:Organic carbon stored in forest soils(SOC)represents an important element of the global C cycle.It is thought that the C storage capacity of the stable pool can be enhanced by increasing forest productivity...

Improving precision of field inventory estimation of aboveground biomass through an alternative view on plot biomass
《Forest Ecosystems》2020年第4期760-769,共10页Christoph Kleinn Steen Magnussen Nils Nölke Paul Magdon Juan GabrielÁlvarez-González Lutz Fehrmann César Pérez-Cruzado 
We contrast a new continuous approach(CA)for estimating plot-level above-ground biomass(AGB)in forest inventories with the current approach of estimating AGB exclusively from the tree-level AGB predicted for each tree...

Spatial and temporal analysis of beta diversity in the Barro Colorado Island forest dynamics plot, Panama被引量：6
《Forest Ecosystems》2019年第1期76-86,共11页Pierre Legendre Richard Condit 
support of the U.S. National Science Foundation (awards 8206992, 8906869, 9405933, 9909947, 0948585 to S.P. Hubbell);the John D. and Catherine D. McArthur Foundation;the Smithsonian Tropical Research Institute;supported by research grant #7738 from the Natural Sciences and Engineering Research Council of Canada (NSERC) to P. Legendre
Background: Ecologists are interested in assessing the spatial and temporal variation in ecological surveys repeated over time. This paper compares the 1985 and 2015 surveys of the Barro Colorado Forest Dynamics plot(...

Background： The first three censuses of the 50-ha plot at Barro Colorado Island spanned an unusually harsh dry season during the 1983 El Nitro. By the early 1990s, we had documented increases in tree mortality, tree ...
