The objective of this research was to evaluate the influence of abiotic factors on the ecophysiological aspects of Handroanthus impetiginosus and Handroanthus serratifolius throughout the day, as well as to indicate the ideal time for ecophysiological evaluations. The design was entirely randomized, with ten treatments and six repetitions for each species. The treatments used were ten evaluation times throughout the day (8h-17h) with an interval of one hour between them. Climatic variables evaluated were internal and external temperature, relative humidity of the internal and external air of the greenhouse and the photosynthetically active radiation of the environment. Ecophysiological aspects evaluated were: net CO2 assimilation, stomatal conductance, transpiration, internal CO2 concentration, vapor pressure deficit, instantaneous water use efficiency, intrinsic water use efficiency and instantaneous carboxylation efficiency. The canonical correlation analysis and principle component analysis were used to verify associations between climatic and ecophysiological variables. In both species, climatic variables were correlated with ecophysiological variables, with higher association between photosynthetically active radiation, internal and external temperature of environment, with the rate of net CO2 assimilation, stomatal conductance, transpiration, instantaneous carboxylation efficiency and vapor pressure deficit. The influence of climatic factors on the ecophysiological aspects of H. impetiginosus and H. serratifolius was verified. In both species, the ideal time of day for measuring ecophysiological variables is between 11h and 13h.

This study estimated the severity of Nilahue-Barahona and Las Máquinas wildfires, occurred in central Chile during the summer of 2016-17, by an empirical-statistical modelling based on preand post-fire arithmetic differences of spectral indices sensitive to vigor, turgor and calcination states of vegetation. By doing this, map of damages were created to aid the efficient management and ecological restoration of disturbed forestry ecosystems. The index differences were calculated from Sentinel-2 satellite images, acquired anually in the summers spanning from 2016 to 2019. The resulting nine index-derived differences were used as predictors of burn severity, field-measured during the summer of 2019 using the CBI (composite burn index) method, into a linear stepwise regression that allowed for selecting those with the highest predictability. CBI yielded low correlations as its calculation includes low vegetation strata largely recovered at the time of the field data collection. However, when overstory field data were used alone, correlations increased (70 % of the data ≥ 0.80, P < 0.05). This was because this stratum was still appreciably damaged during the field campaign, along with its best representation from the image planimetry. The burn severity of both wildfires was mapped using the overstory data as regressand in a model based on NDWIex-ante-2019, NDWIex-ante-2018, NBRex-ante-2018 and NBRex-ante-2017 differences (R 2 ad = 0.77, RMSE = 0.35).
本研究基于植被活力、膨胀和煅烧状态敏感的光谱指数在火灾前后的算法差异，通过经验统计模型估计了2016-17年夏季智利中部Nilahue-Barahona和Las Máquinas野火的严重程度。通过这样做，创建了损害地图，以帮助有效管理和生态恢复受干扰的森林生态系统。这些指数差异是根据2016年至2019年每年夏季采集的Sentinel-2卫星图像计算的。由此产生的9个指数衍生的差异被用作烧伤严重程度的预测因子，在2019年夏季使用CBI(复合烧伤指数)方法进行现场测量，并进入线性逐步回归，从而选择具有最高可预测性的差异。CBI的相关性较低，因为它的计算包括在现场数据收集时大部分恢复的低植被层。然而，当单独使用林场数据时，相关性增加(70%的数据≥0.80,P < 0.05)。这是因为该地层在现场作业中仍然受到明显的破坏，而且它的最佳表现来自图像平面测量。在基于NDWIex-ante-2019、NDWIex-ante-2018、NBRex-ante-2018和NBRex-ante-2017差异(r2 ad = 0.77, RMSE = 0.35)的模型中，将两场野火的烧伤严重程度作为回归数据进行映射。

Biomass additivity is a desirable characteristic of a system of equations for predicting components and total biomass, since equations independently adjusted generate biologically inconsistent results. The aim of this study was to fit and compare three methods for modelling biomass: (i) total biomass individual regression, (ii) total biomass regression function calculated as the sum of separate biomass components, and (iii) simultaneous equations of biomass components based on Nonlinear Seemingly Unrelated Regression. A total of 208 trees of Eucalyptus dunnii and Eucalyptus grandis were harvested and destructively sampled to record above-ground biomass. Results indicate that a system of equations adjusted by simultaneous equations provides accurate biomass estimations, guaranteeing additivity. This model system showed good fit and good prediction performance, given that the correlation coefficient was higher than 97 % for total above-ground biomass, for both species; whereas root mean square error was 23.9 kg and 30.2 kg for E. grandis and E. dunnii, respectively. A system of biomass equations was developed for each eucalyptus species, such that the sum of the estimations of the biomass components equaled the estimate of above-ground biomass. Results showed that the systems of equations have high potential for improving the accuracy of individual tree above-ground biomass estimates for both species.

Arid and semiarid environments dominate the Earth’s surface and are very vulnerable to global change. Chañar ( Geoffroea decorticans ) and brea ( Parkinsonia praecox ) are two ubiquitous woody species of these environments. They grow in degraded forests, strongly modified areas and as a main component of secondary forests. Despite the value of both species, little is known about their growth dynamics and their relationship with climate. The objective of this research was to determine their dendrochronological potential and the connection between growth and climate variables. Anatomical and standard dendrochronological methods were applied. First of all, we stated the anatomical characteristics that allowed us to detect tree-ring boundaries (terminal parenchyma and variation in the shape of vessels). Further, after dating and measurement of tree rings we determined significant correlation between series, which means a common growth signal among trees as a result of environmental variable effects. Trees were not older than 40 years. Mean annual radial growth was 3.37 mm (SD±0.71) and 2.16 mm (SD±0.61) for chañar and brea, respectively. Finally, chañar and brea had a negative growth-mean temperature association. Rainfall affected chañar and brea growth in summer previous to the growing season. Southern Oscillation Index (SOI) had an inverse association with growth of brea. This means, in the case of brea, a significant association with local (temperature and rainfall) and global (SOI) climate variables. These results evidenced the growth dynamics of both species and their value for dendroclimatological studies for the first time.
干旱和半干旱环境主导着地球表面，非常容易受到全球变化的影响。Chañar (Geoffroea decorticans)和brea (Parkinsonia praecox)是这些环境中普遍存在的两种木本物种。它们生长在退化森林、强改造地区和次生林的主要组成部分。尽管这两个物种都很有价值，但人们对它们的生长动态及其与气候的关系知之甚少。本研究的目的是确定它们的树年代学潜力以及生长与气候变量之间的联系。采用了解剖学和标准的树木年代学方法。首先，我们陈述了解剖特征，使我们能够检测树轮边界(末端薄壁和血管形状的变化)。此外，在对树木年轮进行定年和测量后，我们确定了序列之间的显著相关性，这意味着由于环境变量的影响，树木之间存在共同的生长信号。树木的树龄不超过40年。chañar和brea的年均径向生长量分别为3.37 mm (SD±0.71)和2.16 mm (SD±0.61)。最后，chañar和brea的生长与平均温度呈负相关。在生长季节之前的夏季，降雨影响了chañar和brea的生长。南方涛动指数(SOI)与海平面生长呈负相关。这意味着，在brea的情况下，与当地(温度和降雨)和全球(SOI)气候变量的显著关联。这些结果首次证明了两种树种的生长动态及其在树木气候学研究中的价值。

Obtaining high-quality native species seedlings and sustainable alternatives for seedling production are currently some of the bottlenecks for successful restoration plantings in degraded ecosystems. This study evaluated the survival and vigor of seminal seedlings of Mimosa flocculosa, M. micropteris and M. incana, produced in three containers (110 cm3 and 55 cm3 polypropylene tubes and 58 cm3 SISBGC type biocompostable container) for ecological restoration purposes in the phytogeographic region of Mixed Ombrophilous Forest. Survival, total height, stem diameter, shoot and root dry biomass, sturdiness quotient, Dickson’s quality index and technical efficiency were evaluated. Survival percentages were higher for the three Mimosa species throughout all evaluations and in the three containers, with an average over 95 %, demonstrating the viability of the seedling production protocol used. Although the 110 cm3 tube favored larger seedling growth, especially in M. flocculosa, the SISBGC tube showed similar efficiency for M. micropteris and M. incana. We conclude that a good performance in the nursery, associated with the bio-decomposition characteristics, makes SISBGC an excellent alternative for producing native seedlings for ecological restoration purposes.
