Abstract Human activities have altered disturbance patterns in many parts of world, but there is no quantitative information on and trends forest regimes China. We applied a spectral-temporal segmentation approach over all available Landsat data to map individual patches characterize the rate, size, frequency, severity across China’s forests. From 1986 2020, about 39.7% forests were disturbed with an annual rate 1.16 ± 0.41% yr −1 . The decreased at −390 142 km 2 , primarily driven by...
Most temperate forests in U.S. are recovering from heavy exploitation and intermediate successional stages where partial tree harvest is the primary disturbance. Changes regional forest composition response to climate change often predicted for plant functional types using biophysical process models. These models usually simplify simulation of succession may not consider important species‐specific demographic processes driving changes. We determined relative importance succession, harvest,...
LANDIS PRO predicts forest composition and structure changes incorporating species‐, stand‐, landscape‐scales processes at regional scales. Species‐scale include tree growth, establishment, mortality. Stand‐scale contain density‐ size‐related resource competition that regulates self‐thinning seedling establishment. Landscape‐scale seed dispersal disturbances. is designed to be compatible with inventory data, thus extensive data can directly utilized initialize calibrate model parameters...
Alpine treeline ecotones are highly sensitive to climate warming. The low temperature-determined alpine is expected shift upwards in response global However, little known about how temperature interacts with other important factors influence the distribution range of tree species within and beyond ecotone. Hence, we used a GF-2 satellite image, along bioclimatic topographic variables, develop an ensemble suitable habitat model based on modeling algorithms Biomod2. We investigated habitats...
Abstract Tree harvest and climate change can interact to have synergistic effects on tree species distribution changes. However, few studies investigated the interactive of distributions. We assessed 29 dominant at 270 m resolution in southern United States, while accounting for demography, competition, urban growth natural fire. simulated changes year 2100 using a coupled forest dynamic model ( LANDIS PRO ), ecosystem process LINKAGES ) SLEUTH ). The distributions 20 contracted nine...
Two challenges confronting forest landscape models (FLMs) are how to simulate fine, stand‐scale processes while making large‐scale (i.e., >10 7 ha) simulation possible, and take advantage of extensive inventory data such as U.S. Forest Inventory Analysis (FIA) initialize constrain model parameters. We present the LANDIS PRO that addresses these needs. adds density size mechanisms resource competition. This is achieved through incorporating number trees DBH by species age cohort within...
ABSTRACT Human‐driven land use changes significantly contribute to habitat loss and fragmentation in temperate forests, prompting the implementation of ecological conservation programs. However, these efforts may be undermined by competing demands economic development. This study assessed forest quality relative contribution decisions (ecological programs, cropland expansion, urbanization) Changbai Mountain region, Northeast China from 1990 2050. Our results revealed a region‐wide decline...
Woody plant encroachment (WPE), a widespread ecological phenomenon globally, has significant impacts on ecosystem structure and functions. However, little is known about how WPE affects phenology in wetland ecosystems of middle high latitudes. Here, we investigated the regional-scale effects start (SOS), peak (POS), end (EOS), length (GSL) growing season boreal ecosystems, their underlying mechanisms, using remote sensing dataset during 2001–2016. Our results showed that advanced annual SOS...
Forest landscape models (FLMs) are an important tool for assessing the long-term cumulative effects of harvest over large spatial extents. However, they have not been commonly used to guide forest management planning and on-the-ground operations. This is largely because FLMs track relatively simplistic vegetation information such as age cohort presence/absence, type, biomass that incompatible with tree density size on which most prescriptions based. We describe demonstrate newly developed...
Abstract Aim Population dynamics and disturbances have often been simplified or ignored when predicting regional‐scale tree species distributions in response to climate change current climate‐distribution models (e.g., niche biophysical process models). We determined the relative importance of population dynamics, harvest, change, their interaction affecting distribution changes. Location Central Hardwood Forest Region United States. Major taxa studied Tree species. Methods used a forest...
Shifts in alpine tundra plant species have important consequences for biodiversity and ecosystem services. However, recent research on upward shifts focused mainly polar high-latitude regions it therefore remains unclear whether such vegetation change trends also are applicable to the at southern edges of distribution. This study evaluated an region within Changbai Mountains, China, that is part southernmost eastern Eurasia. We investigated Mountains over last three decades (1984–2015) by...
Abstract The Central Hardwood Forest (CHF) in the United States is currently a major carbon sink, there are uncertainties how long current sink will persist and if CHF eventually become source. We used multi-model ensemble to investigate aboveground density of from 2010 2300 under climate. Simulations were done using one representative model for each simple, intermediate, complex demographic approaches ( ED2, LANDIS PRO , LINKAGES respectively). All agreed that would at least 2100. However,...
Oak decline is a process induced by complex interactions of predisposing factors, inciting and contributing factors operating at tree, stand, landscape scales. It has greatly altered species composition stand structure in affected areas. Thinning, clearcutting, group selection are widely adopted harvest alternatives for reducing forest vulnerability to oak removing susceptible declining trees. However, the long-term, landscape-scale effects these different not well studied because limited...
Abstract Temperate forests regrowing from historical land use and cover change in the eastern US serve as carbon (C) sinks. Environmental drivers have been significantly altered (e.g. rising atmospheric CO 2 concentration, warmer temperature, elevated nitrogen (N) deposition) will a wide range of impacts on future forest C However, interactions among these environmental are unclear their effects subject to uncertainty. We assessed combined interactive climate (temperature, precipitation), N...
Abstract Bacterial leaf blight ( BB ) is among the “top 3” diseases in rice production. Breeding resistant cultivars has been most effective strategy for management. The inbred cultivar Baixiangzhan BXZ showed a broad spectrum of resistance to five Xoo pathotypes China, including prevalent and highly virulent Chinese Race V (CV), which can overcome Xa4 Xa21 . heredity explored this study. A single recessive major gene, designated as xa42 t ), confers against tested CV. Linkage analysis lands...
