Human-induced global changes, including anthropogenic climate change, biotic globalization, trophic downgrading and pervasive land-use intensification, are transforming Earth's biosphere, placing biodiversity ecosystems at the forefront of unprecedented challenges. The Anthropocene, characterized by importance Homo sapiens in shaping Earth system, necessitates a re-evaluation our understanding stewardship ecosystems. This theme issue delves into multifaceted challenges posed ongoing ecological planetary transformation explores potential solutions across four key subthemes. Firstly, it investigates functioning emerging novel ecosystems, emphasizing urgent need to comprehend dynamics under uncharted conditions. second subtheme focuses on projections recognizing necessity predicting shifts Anthropocene. Importantly, inherent uncertainties complexity responses environmental stressors pose for societal accurate change. RAD framework (resist-accept-direct) is highlighted as flexible yet nuanced decision-making tool that recognizes adaptive approaches, providing insights directing adapting Anthropocene while minimizing negative impacts. imperative extend temporal perspective beyond 2100 emphasized, given irreversible changes already set motion.

Monitoring the extent to which invasive alien species (IAS) negatively impact environment is crucial for understanding and mitigating biological invasions. Indeed, such information vital achieving Target 6 of Kunming–Montreal Global Biodiversity Framework. However, to-date indicators tracking environmental impacts IAS have been either lacking or insufficient. Capitalizing on advances in data availability assessment protocols, we developed track realized potential IAS. We also an status indicator assess adequacy underlying indicators. used 75 naturalized amphibians from 82 countries demonstrate at a global scale.

Biological invasions stand among the main anthropogenic threats to ecosystems globally while causing multitrillion-dollar impacts. Surprisingly, trait-based frameworks have been designed predict invasion success and invader ecological impacts, no such approaches exist understand economic We propose first framework by bridging evolutionary biology of traits escalation costs. Previously acquired can benefit performance, their rapid change could exacerbate impacts through adaptive non-adaptive processes during invasion, as natural selection, genetic drift, or phenotypic plasticity. Emerging evidence suggests that some organismal determine impact magnitudes. discuss new transdisciplinary avenues inform cost forecasting management responses for current future biological invasions.

Abstract Biological invasions pose significant threats to biodiversity, while impacting ecosystem services, human health, and cultural heritage. Despite these far-ranging effects, their impacts are generally underappreciated by both the public policymakers, resulting in insufficient management inadequate conservation outcomes. Recognizing gap effective quantitative measurement tools, we introduce Extinction Potential Metric (EPM) its derivative, EPM for Unique species (EPM-U; adjusted phylogenetic uniqueness) quantify ecological damage caused invasive alien (IAS). These metrics estimate number of current projected extinct within a 50-year horizon under business-as-usual scenario due specific IAS. We applied EPM-U assess native terrestrial vertebrates from IAS, examining on 2178 amphibians, 920 birds, 865 reptiles, 473 mammals. The analysis identified that mostly stems limited notably two pathogenic fungi affecting amphibians (up 380 equivalent species) primarily cats (139 rats (50 other groups, through mechanisms such as predation, disease, reduced reproductive success birds. proposed not only provide standardised measure but sufficiently versatile be tailored spatial temporal scales or taxonomic groups.
