Summary: The study found that a large flood in 2014 caused silver poplar trees in the semi-arid High Atlas Mountains of Morocco to exhibit dual, opposite growth reactions in the following year, with half of the trees developing wider rings and the other half developing narrower rings. The wide rings were attributed to a sudden supply of water benefitting the trees, while the narrower rings were a result of environmental stress related to sediment deposits from the flood. This demonstrates the importance of considering detailed analysis of individual tree responses to environmental events, rather than relying solely on average ring widths.

Summary: Dendroclimatology uses tree rings to reconstruct past climate, and historical wood from buildings can extend this information. However, the origin of timbers affects the sensitivity of tree-ring samples. This study compares tree rings of larch trees to develop classification models using machine learning algorithms and finds that the density-based models, particularly the larch-specific density model, perform the best in determining the climate sensitivity and provenance of historical series.

Summary: This study integrated historical data and remote sensing-based landscape analyses to understand the landscape development of a large remnant floodplain and evaluate the present-day utilization of different river-floodplain habitat types. The results showed drastic transformation of the landscape due to river regulation works, resulting in the conversion of wetlands to agricultural land and a significant decrease in aquatic habitat area. The evaluation of present-day land use indicated that protected areas have higher potential for the maintenance of aquatic biodiversity. However, past changes and present-day utilization limit conservation and restoration possibilities.

Summary: This study investigated the short- and long-term responses of redwood physiology, growth, and forest biodiversity to restoration thinning treatments in second-growth redwood forests. The results showed that thinning treatments did not significantly impact tree water potential, increased tree stomatal conductance in the short-term, improved tree growth in the long-term, increased understory plant diversity, and had no effect on bird or mammal diversity. These findings demonstrate the potential of thinning treatments to accelerate the development of old-growth characteristics in redwood forests, providing important information for land managers and future assessments of restoration efforts.

Summary: This paper compiles and analyzes the literature on vegetation index research based on tree-ring information in the past 20 years. It provides an overview of the relationship between tree-ring parameters and NDVI, as well as NDVI reconstruction. The research shows a strong correlation between tree-ring parameters and NDVI in summer. In addition, combining tree rings with NDVI is useful for assessing forest decline, quantifying the forest response to drought, and monitoring forest productivity. Future research should consider multiple environmental factors and conduct large-scale studies on the climate response of forest tree growth and the reconstruction of historical vegetation index sequences.

Summary: Human activities, particularly cultivated-land reclamation, have a significant impact on landscape patterns and lead to a decline in wetland areas and function. This study focused on a farmland-wetland mosaic landscape in the Sanjiang Plain and explored the effects of changing cultivated land patterns on remnant wetland degradation. Soil and vegetation indicators were used to model the integrated degradation degree of remnant wetlands (IDRW), and the correlation between cultivated land patterns and IDRW was analyzed. The study found that the variation in soil and vegetation indicators caused by changing cultivated land patterns could be used to model IDRW, and the aggregation degree of wetland patches was the main landscape index for IDRW simulation.

Summary: The study demonstrates how the Australian landscape was heavily influenced by Indigenous land management practices prior to British invasion in the 18th century, and how the disruption of these practices led to ecological succession and encroachment of cool temperate rainforest into important grasslands. It challenges the traditional portrayal of Indigenous Australians as low-impact 'hunter-gatherers' and emphasizes the importance of Indigenous fire management in the face of increased bushfire risk and biodiversity loss.

Summary: The need to understand natural climate variability and improve weather forecasts led to the development of the first tree-ring reconstructions over a century ago in Europe and North America. This motivation still drives modern paleoclimatology, which aims to learn from the past in order to prepare for the future.

Summary: This study focuses on dendrochronology and dendroclimatology of yew in Poland. The analysis was conducted on 34 protected yew populations, with a total of 774 trees sampled. The study found that yew tree age is often overestimated, with most populations being 100-200 years old. The study also identified the relationship between tree-ring width and air temperature, particularly in winter, pre-spring, and early spring.

Summary: Industrial activities and human population growth have led to a significant increase in particulate matter release, with widespread nanoparticle contamination threatening terrestrial and aquatic ecosystems. Trees have the capability to serve as bioindicators and proxy recorders of past air pollution, with the potential to absorb and translocate nanoparticles. Tree-ring chemistry has been successfully used to reconstruct trace metal deposition from various pollution sources, showing promise in monitoring atmospheric nanoparticle contamination.

Summary: The study found that precipitation is the key factor influencing the growth of A. borisii-regis trees under Mediterranean climate conditions, while temperature has a relatively small impact on tree growth. Precipitation in June, May, and July shows a high correlation with tree-ring width, while snow does not significantly affect tree growth.

Summary: Tree-ring measurements are crucial in many scientific disciplines, but some species like Hawaiian Sandalwood can exhibit complex growth features that make these measurements challenging. A new two-dimensional transect methodology and software called svg-dendro have been developed to analyze difficult cross-sections of Sandalwood stems. This new method has shown improved sensitivity to tree-ring variability and highlighted the challenges of measuring trees with wedging features.

Summary: This study built tree-ring width (TRW), stable carbon isotope ratio (delta C-13), and intrinsic water use efficiency (iWUE) data set chronologies for two oak species in northwestern Serbia. The results showed that Turkey oak exhibited better drought tolerance compared to pedunculate oak and delta C-13 responded more strongly and rapidly to climate variations than TRW.

Summary: In the context of forecasted climate change scenarios, the growth of forest tree species at their distribution margin is crucial to adapt current forest management strategies. This study analyzed the growth of beech populations in the Republic of Moldova and found that the marginal populations had higher growth rates compared to core distribution sites. The study also revealed a significant response of beech growth to climatic variables, particularly vapor pressure deficit (VPD), indicating that water deficit is a limiting factor for beech growth in the region.

Summary: This study analyzed 18 years of acorn production data for black oak and chestnut oak to investigate the relationship between resources, weather, and masting. The results showed species-specific responses to silvicultural treatments, with chestnut oak reproduction being influenced by warm spring temperatures and changes in summer temperatures. The study supported the importance of both resources and weather in masting in oaks and highlighted the need to include both factors in predictive models for acorn production under current and future climate conditions.

Summary: Masting is a reproductive strategy in which individuals synchronize intermittent seed production. This study examined the individual differences in reproductive effort and variability among chestnut oak and black oak. The results showed that diameter at breast height (DBH) was the most consistent variable for explaining intraspecific variation in reproduction. Other influential factors included elevation, clay content, and slope. Thinning treatment did not have a significant effect on acorn production.
