Anthropogenic effects, as a biological process, encompass the direct and indirect impacts of human activities on biological systems, altering organismal physiology, behavior, population dynamics, community structure, and ecosystem function. These effects arise from mechanisms such as habitat modification, pollution, overexploitation, introduction of invasive species, and climate forcing via greenhouse gas emissions. At the biological level, anthropogenic effects drive phenotypic plasticity, rapid evolutionary change, altered life-history strategies, and disrupted species interactions (e.g., predation, competition, mutualism). They also modify biogeochemical cycles, primary productivity, and trophic networks, frequently resulting in biodiversity loss, shifts in species ranges, and changes in ecosystem resilience and stability.
U.S. forests have stored more carbon in the past two decades than at any time in the last century, an increase attributable to a mix of natural factors and human activity, finds a new study.
