We commend Chludil et al. (2025) for exploring novel ways to help forest trees adapt to new climates. We also recognize the many challenges involved in implementing assisted migration in forestry, especially when there is societal resistance or policy barriers to moving genetic materials across geopolitical boundaries. However, pollen-based assisted migration (AM) faces several major hurdles, and the

Our recent publication on pollen‐based assisted migration has prompted concerns about its feasibility and effectiveness. In this response article, we address those concerns by presenting large‐scale examples of supplemental and controlled pollination from Sweden and the United States, demonstrating its practical application. We also highlight the existence of an extensive global network of seed orchards

The photic zones of the oceans—where sunlight and moonlight drive ecological interactions—are one of the most productive habitats on the planet and fundamental to the maintenance of healthy global biogeochemical cycles. Ocean darkening occurs when changes in the optical properties of the oceans reduce the depth to which sufficient light penetrates to facilitate biological processes guided by sunlight

The need for increasing the environmental friendliness of food systems is driving regulatory initiatives aimed at reducing the use of pesticides and supporting organic farming. This scenario is casting a shadow over the suitability of modern cultivars that—shaped by the Green Revolution—have lost competitiveness against weeds. In this context, reducing the use of herbicides could rapidly become a critical

We have committed to ambitious targets under the Global Biodiversity Framework, but projected climate change makes the achievement of many of these targets extremely difficult and will effectively require a significant rethinking in how to achieve multiple targets. In this Opinion, we have chosen to focus on selected targets, considering how their achievement is likely to be compromised by climate

Measuring organismal responses to environmental perturbation and determining whether species are capable of adaptation in a changing world is a perpetual challenge for biologists, particularly when anthropogenic processes are altering ecosystems at an alarming rate. Classic textbook examples of phenotypic change as a response to varying environmental conditions include beak size and shape fluctuations

Healthy, verdant forest ecosystems are indicated by an intact complement of highly abundant vegetation along with diverse and abundant populations of herbivore species and their carnivore predators (Wang et al. 2025). Keeping forest ecosystems verdant is considered vital to ensuring planetary resilience to climate change (Watson et al. 2018). This is because the highly abundant vegetation takes up

Global change, particularly the changes in atmospheric CO2 concentration, climatic variables, and nitrogen deposition, has been widely recognized and examined to have worldwide impacts on forest carbon. However, its influence on forest area required to meet the demand for timber and carbon storage and subsequent land use and land cover change (LULCC) is rarely studied. This study explores the role
