The ongoing climate crisis represents a growing threat for plants and other organisms. However, how if will be able to adapt future environmental conditions is still debated. One of the most powerful mechanisms allowing tackle changing phenotypic plasticity, which can regulated by epigenetic mechanisms. Environmentally induced variation mediating plasticity might heritable across (a)sexual generations, thus potentially enabling rapid adaptation change. Here, we assessed whether mechanisms, DNA methylation in particular, enable local response increased and/or decreased temperature natural populations clonal plant, Fragaria vesca (wild strawberry). We collected ramets from three along gradient each countries covering southern (Italy), central (Czechia), northern (Norway) edges native European range F. vesca.

The conservation of threatened species and the restoration ecosystems have emerged as crucial ecological prerequisites in context a changing global environment. One such significant commercial value is Bael tree, scientifically known Aegle marmelos, which native to semi-arid regions Pakistan. However, faces threats Pakistan due overexploitation land use. To support sustainable production practices agricultural planning, it important investigate how climate change has affected geographic distribution marmelos. Additionally, impact on its frequency remains uncertain. address these concerns, we employed modeling techniques using MaxEnt GIS predict present future favorable habitats for Based our findings, several key bioclimatic variables were identified influencers marmelos distribution. These include soil bulk density (bdod), isothermality (bio03), precipitation during warmest quarter (bio18), mean temperature wettest (bio08). Currently, potential suitable habitat spans an area approximately 396,869 square kilometers, primarily concentrated Punjab, Khyber Pakhtunkhwa, Balochistan deemed highly are predominantly found upper central Punjab. if persists, likely become more fragmented, resulting shift overall area. Moreover, center expected relocate towards southeast, leading increased spatial separation over time. results this research significantly contribute understanding geo-ecological aspects related Furthermore, they provide valuable recommendations protection, management, monitoring, species.

Fire is a major disturbance affecting plant communities in terrestrial ecosystems. Understanding fire effects on soil seed banks critical the context of altered global regimes. Through systematic and quantitative review literature, we provide first assessment how respond to based 539 paired comparisons. The overall bank richness (i.e., species bank) abundance were negative neutral, respectively. Wildfires high-intensity fires led greater decreases than prescribed burns low-severity fires, As an important cue, presence simulated smoke increased abundance, but heat shock had no effect both two metrics, contrast findings previous empirical studies. Strong, positive found Mediterranean ecosystems, for forest especially tropical forests. Both tree decreased after fire. Burning only habitats with history or short history. time elapsed post-fire, also increased. Overall, tended decrease globally, this was case high-severity non-fire-prone Our enhance our understanding spatiotemporal variability banks, highlight importance monitoring post-fire composition across crucial implications vegetation regeneration ecosystem recovery.

Lianas Significantly Reduce Tree Performance and Biomass Accumulation Across Tropical Forests: A Global Meta-Analysis

Frontiers in Forests and Global Change, Journal Year: 2022, Volume and Issue: 4

Published: Feb. 11, 2022

Lianas are a quintessential tropical plant growth-form; they speciose and abundant in forests worldwide. compete intensely with trees, reducing nearly all aspects of tree performance. However, the negative effects lianas on trees have never been combined quantified for multiple forests. Here, we present first comprehensive standardized quantification effect across We used data from 50 liana removal experiments size growth, biomass accretion, reproduction, mortality, leaf water potential, sap flow velocity, area index (LAI) different forest types. Using three-level mixed-effect meta-analysis, found unequivocal evidence that significantly reduce growth accretion ecological, logging, silvicultural studies. also recruitment, physiological The relative detrimental does not increase drier forests, where tend to be more abundant. Our results highlight substantial liana-induced reduction performance accumulation, provide quantitative essential large-scale demographic ecosystem models predict change carbon dynamics.

Abstract Crown radius (CR) and crown width are fundamental indicators used to describe tree sizes widely included as predictors in growth yield models. is the arithmetic average of two perpendicular diameters each other, obtained from measurements four radii: east, south, west, north. Climate change soil variations influence physiological activities trees, thereby impacting development. However, most CR studies do not quantify impact climate factors on CR. In this study, we developed a nonlinear mixed-effects simultaneous model system address above problems. This study 7188 trees 98 plantation plots Korean pine (Pinus koraiensis) northeast China. The results showed that (extreme temperature precipitation) (total nitrogen) variables improved performance system. large-sized was more sensitive compared smaller trees. Incorporating plot-level random effects into both fitting accuracy predictive width. Our provide new insights environmental variability planted forests suggest integrating modeling can improve results. These findings may become relevant for improving forest management strategies under changing conditions.

Mountains present challenging habitats for biological conservation assessment and intervention. Atmospheric warming is pressuring populations, communities ecosystems to move toward higher elevations, but increasingly variable precipitation patterns could enhance or reverse the upward trend. The effects of pressure from lower elevations combined with irregular annual pulses will be complicated by squeeze cause decreasing habitat area at elevations. Given evidence date this raises question, can species' distributions on mountains ever in climatic equilibrium?
