TL;DR: Assessment of causal agents and rates of tree mortality, and short-term impacts to forest structure and composition based on a network of fixed-radius plots on the Eldorado, Stanislaus, Sierra and Sequoia National Forests found that tree mortality was most severe and tree regeneration was dominated by C. decurrens and Quercus spp.

TL;DR: In the last three decades, over 4.1 million hectares have burned in Arizona and New Mexico and the largest fires in documented history have occurred in the past two decades as discussed by the authors.

TL;DR: Several contrasting growth-structure correlations are reviewed and linked to forest processes by considering the different types of tree interactions they are associated with and the implications for selecting which structural variables to use and when scaling up to the stand level are discussed.

TL;DR: In this paper, the authors examine where and when plantations with regular tree spacing elevate the risk of future mortality, and how planting density, spatial arrangement, and species composition might be modified to increase seedling and sapling survival through recurring drought and fire events.

TL;DR: In this paper, the effects of different types of agroforestry systems on biodiversity and ecosystem services in the Brazilian Atlantic Forest were quantified using 72 studies encompassing 143 study sites and 1700 quantitative comparisons.

TL;DR: In this paper, the authors identified management options for forestry and nature conservation that sustain both the ecological value of oak forests and the economic viability of oak silviculture, and identified an urgent need for systematic forest planning approaches that secure the long-term availability of these structural features within areas or sustainability units that are large enough to maintain viable populations of oak woodland specialist species.

TL;DR: In this paper, the impact of forest cover on water supply, hydrological regulation and mitigation of erosion and landslides in the Andean region has been studied using meta-analyses and meta-regressions.

TL;DR: In this article, four machine learning algorithms (MLAs) are compared regarding their ability to estimate forest parameters of black locust plantations on the Loess Plateau, and the results indicated that among the four MLAs, the CART method achieved the lowest accuracy, the SVM and ANN methods had moderate performances and the RF algorithm was chosen to predict the forest parameters.

TL;DR: In this paper, the currently available lidar system types (ground, air, and space-based), highlight opportunities and challenges associated with each system and suggest pathways for lidar to further contribute to addressing questions in forest ecosystem science and increase benefits to a wider community of researchers.

TL;DR: The findings suggest that the occurrence of conservation-relevant species is a sound and relevant metric for planning and evaluating conservation actions, especially for less studied organism groups (e.g., saproxylic fungi and epiphytes).

TL;DR: In this paper, the direct and indirect effects of climate and soils on aboveground biomass via species diversity and stand structural complexity were examined in tropical forests of Hainan Island, Southern China.

TL;DR: Wang et al. as mentioned in this paper studied the relationship between urbanization rate and temperature in the Pearl-River-Delta metropolitan region (PRDR) in southern China. And they found that the cooling effects of ecological land loss and gain are significantly different, which provides evidence that the existing natural ecosystems are valuable for climate adaptation because newly constructed ecological land does not provide the same cooling effect.

TL;DR: In this article, the authors studied the impacts of mangrove conversion on carbon losses and therefore their values in climate change mitigation, and sampled 10 intact mangroves and 10 abandoned shrimp ponds to quantify: (1) the total ecosystem carbon stocks; (2) potential CO2 emissions arising from mangroVE conversion to shrimp ponds; and (3) the land use carbon footprints of shrimp production.

TL;DR: In this paper, structural attributes of forest canopies undergoing restoration in the Atlantic Forest of Brazil using a portable ground lidar remote sensing device as a proxy for airborne laser scanners were analyzed.

TL;DR: In this paper, the authors identified the main environmental factors driving fire severity in extreme fire events in Pinus fire prone ecosystems, providing management recommendations for reducing fire effects, and highlighted the potential of low-density LiDAR for evaluating fuel structure throughout the coefficient of variation of heights.

TL;DR: In this article, the authors investigated the impacts of forest management and structural heterogeneity on the diurnal temperature range (DTR) in 128 managed forest stands in three climatically different locations (Swabian Alb, Hainich-Dun and Schorfheide-Chorin) in Central Europe.

TL;DR: In this article, a reproducible and open-source methodology using the R programming language for estimating leaf area density (LAD; the total leaf area per unit of volume) from airborne LiDAR is described.

TL;DR: In this article, the effects of conversion from natural forest to coniferous plantations on soil microbial community structure, biodiversity, and co-occurrence networks, as well as soil chemical properties were investigated.

TL;DR: In this article, the authors investigated the influence of forest management, forest cover in the surrounding landscape (25 km radius), forest type, the number of standing dead trees, altitude and mean diameter at breast height (DBH) on the abundance and diversity of TreM on living trees.

TL;DR: In this paper, the authors quantify the future regulating service supply from a 6456ha landscape in the Stubai valley in Tyrol, Austria, and assess the relative importance of management, climate, and natural disturbances on the future supply of regulating ecosystem services.

TL;DR: In this paper, the authors conducted a field study of litter decomposition using 15N-labeled litter and found that the temporal patterns of gross N release and immobilization were best described by the one-pool model y = 100 - a 1 ∗ e - k 1 ∆ x and y = a 2 ∗ ( 1 - e -k 2 ∆ ), respectively.

TL;DR: In this paper, the authors synthesize data from 61 coordinated field-based surveys of logging impacts in seven countries across the tropics and estimate that tropical selective logging emitted 834 Tg CO2 in 2015, 6% of total tropical greenhouse gas emissions.

TL;DR: In this paper, the authors measured the impact of forest plantations on biodiversity with a focus on eight groups of biota including saproxylic and ground mycorrhizal fungi, lichens, herbs together with shrubs, tree seedlings, aculeate hymenopterans, beetles and birds, in patches with formerly continuous vegetation dominated by native oak and in patches in spruce plantations (reflecting spatiotemporal discontinuity) in the East-Bohemian woodlands of the Czech Republic.

TL;DR: Evidence is provided that changes in the microbial community in mixed A. mangium and E. grandis plantations is correlated with increased C and N cycling, which has implications for increased productivity and environmental sustainability, besides allowing for the optimization of mineral fertilization in forest plantations.

TL;DR: In conclusion, direct seeding was a successful method for the initial phase of forest restoration, promoting a structure that was more similar to resilient natural regeneration sites than to non-resilient natural regeneration Sites and seedling planting sites.

TL;DR: In this paper, the authors developed a comprehensive methodological approach for identifying primary forests, and tested it within one of Europe's hotspots of primary forest abundance: the Carpathian Mountains.

TL;DR: The development of tree diversity–structure–productivity relationships at the stand level and individual tree level in 192 long-term experimental plots in Central Europe is analyzed to provide insights regarding the mechanisms underlying the contradictory findings obtained in recent studies dealing with tree diversity-structure-productivity relationship.

TL;DR: The results show that a heavy thinning treatment (60% of basal area removed) provides a promising silvicultural framework for the adaptation of these drought-sensitive Mediterranean mountain pine forests to the potential risks of climate change.

TL;DR: In this paper, the authors present models of duration-temperature relationships of soil biota and invite interdisciplinary efforts from researchers and managers to directly measure biological responses on a case-by-case basis.

TL;DR: In this paper, the authors investigated the use of UAV-borne thermal systems for detecting disease-induced canopy temperature increase and explored the influence of the imaging time and weather conditions on the detected relationship.
