Summary: Shared ancestral polymorphism and introgression are the main causes of chloroplast DNA haplotype sharing among closely related angiosperms. The haplotype sharing pattern among East Asian Cerris oaks reflects the imprints of both shared ancestral polymorphism and introgression, and is associated with the relatively stable climates and complex landscapes in East Asia.

Summary: This study examined the combined impacts of climate change, land use and land cover change, and dispersal limitations on the future range dynamics of three dominant Cerris oak tree species in warm-temperate and subtropical deciduous forests of China. It was found that precipitation, minimum temperature in the coldest month, and temperature seasonality play key roles in determining the present distributions of the oak tree species. Land use and cover change will increase habitat fragmentation levels, while limited dispersal ability will restrict access to potential future suitable habitats.

Summary: The research conducted in northwest Turkey aimed to predict bark thickness of oak trees based on tree variables, finding species-specific results in Quercus petraea, Quercus frainetto, and Turkey oak. Models based on tree diameter at breast height were found to be accurate in predicting bark thickness.

Summary: This study examines the relationship between present admixture patterns of two East Asian Cerris oaks and past climatic niche suitability, finding that paleoclimate change shapes present admixture patterns by influencing historical range overlap. Specifically, the mid-Pliocene warm climate promoted ancient contact and widespread hybridization, while the Pleistocene cool climate limited interspecific gene flow except in areas with high ecological stability.

Summary: In recent years, there has been growing interest in the pyrolysis of biomass due to economic and environmental reasons. Low-temperature pyrolysis is one of the most straightforward and low-cost pyrolysis processes that may be used to produce added-value biochars as well as liquid and gas products from waste biomass.

Summary: Pyrolysis is a useful technique for characterizing the thermal behavior, kinetics, and chemical composition of new materials. Different cork species exhibit varying pyrolytic degradation patterns, with lignin and suberin contents determining thermal reactivity. Desuberinised cork shows higher heat resistance at high temperatures compared to raw cork.

Summary: This study investigated the seasonal fluctuations and climatic controls of two deciduous forest ecosystems dominated by Fagus sylvatica and a mix of Ouercus cerris and Ouercus frainetto. The results showed different ecophysiological responses between the species, with spring temperature promoting growth processes and rising autumn temperature delaying senescence. Precipitation had asymmetric effects on the measured parameters.

Summary: This study examined the drought-induced growth responses of sessile oak and Turkey oak in south-western Hungary. The results revealed that Turkey oak showed higher sensitivity to drought, lower resistance, and higher recovery potential compared to sessile oak. Additionally, Turkey oak exhibited a linearly proportional increase in growth reduction with rising water stress, while sessile oak's growth response decreased considerably with increasing aridity, indicating its lower growth plasticity to droughts.

Summary: In a mountain forest in Italy, the study found little evidence to support the home-field advantage hypothesis, with the chemical composition being the main factor affecting the early stages of litter decomposition. Tree species and soil properties play a crucial role in the advanced stages of decomposition, controlling the assemblage and functions of the soil microbial community.

Summary: Our study demonstrates predictable evolution over short timescales after admixture in 3 hybrid ant populations, where selection leads to correlated sorting of genetic variation and haplotypes with positive selection signatures are more likely to fix in hybrids.

Summary: This study provides a qualitative and quantitative description of the bark of hybrids between cork oak and holm oak. The hybrids show characteristics intermediate between the parent species and also exhibit unique features, suggesting significant modifications in the genetic expression patterns. These findings highlight the value of hybrid individuals in understanding the molecular mechanisms underlying bark development in angiosperms.

Summary: The study used whole genome sequencing to reconstruct the history of the four species in the Gallus genus, revealing discrepancies in phylogeny reconstruction methods and genomic components. It suggested G. gallus may be the earliest lineage instead of G. varius. The importance of carefully selecting and validating samples in phylogenomics was emphasized.

Summary: This study investigated whether climate sensitivity and growth synchrony of temperate trees have changed under recent climate warming. The results showed that water availability, especially in summer, was the most important factor affecting radial growth in all five species. Recent climate warming has increased the impact of water availability on growth while decreasing the influence of other climate factors in spring and summer. Within-population growth synchrony has increased or remained stable in beech and silver linden, but decreased in oak species. These findings have implications for selecting climate change-adapted tree species in forestry.
