Restoration of native forests from Gorse-dominated shrublands in North Patagonia, Chile: early structural development of mixed plantations Bannister, Jan R.; Cáceres, Natalia; Vidal Ojeda, Osvaldo; Carrasco Farias, Natalia Introduction: Gorse (Ulex europaeus) is currently one of the most invasive shrub-forming species in the world. Active management has been proposed for its control, including mechanical removal, followed by Gorse suppression by competition through planted forests. Objectives: In this study, we evaluate the development of 7-year-old mixed native plantations on Chiloé Island, North Patagonia, which were established following the removal of Gorse-dominated shrublands, and define which microsite conditions can facilitate stand structural development.

Coordination among hydraulic, stomatal, and anatomical traits in Prunus dulcis L. cultivars differing in degree of isohydric and anisohydric behavior Álvarez, Carolina; Acevedo Tapia, Manuel; Sandoval Rocha, Simón Pedro; Estay, Daniela; Valero, Andrea Understanding the mechanisms underlying isohydric and anisohydric behavior in woody species is critical for predicting their performance under increasing drought stress. We combined hydraulic, anatomical, and gas exchange measurements during progressive soil drought and re-watering in three Prunus dulcis cultivars (Avijor, Isabelona, and Soleta) to evaluate how coordinated traits explain drought responses and recovery. Hydroscape analysis confirmed the isohydric–anisohydric ranking previously reported, with Avijor being the most isohydric and Soleta the most anisohydric. Across cultivars, a common sequence of responses was observed: early decline in leaf hydraulic conductivity (Kleaf), followed by turgor loss point (ΨTLP), stomatal closure, and onset of embolism. Despite this shared pattern, cultivars differed in key drought thresholds. The more anisohydric cultivars showed more negative ΨTLP, and Soleta exhibited greater stem embolism resistance than Avijor. Cultivar differentiation was also clearer in stem xylem anatomy than in leaf traits, with variation in vessel-related traits being consistent with differences in stem vulnerability. By contrast, leaf vulnerability thresholds showed no clear differences among cultivars. Relative Kleaf recovery differed among cultivars, with higher recovery in Soleta than in Avijor, while Isabelona was intermediate. This pattern may reflect that Soleta and Isabelona did not reach water potentials lower than their stem P50 during drought, unlike Avijor. The separation between leaf and stem vulnerability thresholds also varied between cultivars and was greatest in Soleta, suggesting possible inter-cultivar variability in hydraulic vulnerability segmentation. Overall, cultivar-level drought responses in almond were explained by differences in stem embolism resistance, ΨTLP, and stem xylem analysis than by stomatal behavior alone. 15 páginas

An operational approach to forest integrity assessment: A case study in temperate forests in Chile Schlegel Heldt, Bastienne; Utrera, María Inés; Vergara Asenjo, Gerardo; Little Cárdenas, Christian Human activities—particularly those driving to degradation—impact the integrity of forests, affecting their capacity to provide multiple goods and services to society. Ecological integrity is a key concept in conservation and forest management; however, the degree of forest modification remains poorly quantified, especially at operational scales. Here, we propose a novel methodological approach to forest integrity assessment from an operational perspective, using data from old-growth forest stands in the Andes range of south-central Chile. The methodological framework combines rapid assessment with 27 categorical variables to characterize forests at the stand level, considering site, structure, regeneration, and degradation drivers, we established three levels of forest integrity (high, medium, low), represented by a traffic light color scheme, to facilitate interpretation and application in forest management. We applied a quantitative analysis through a two-stage statistical approach to identify ecological thresholds in old-growth native forests, allowing us to measure the ecological integrity of forests, identifying structural and regenerative thresholds that serve as a practical operational tool for evaluators, planners, and decision makers in conservation and forest management. 25 páginas
