BMC Ecology and Evolution is calling for submissions to our Collection, Pollinators under pressure: ecology, evolution, and environmental change. Pollinators are important for a healthy and functioning planet, playing a vital role in ecosystem health and food production. Pollinators directly and indirectly support several of the United Nation's Sustainable Development Goals, from SDG 2: Zero Hunger to SDG 15: Life on Land. However, largely due to human activities, pollinator populations are declining worldwide. Almost 35% of invertebrate pollinators, including many bee and butterfly species are facing extinction. Similarly, 17% of vertebrate pollinators, such as bats and hummingbirds, are at risk.

Pollinators face numerous challenges, including habitat loss, climate change, pesticide exposure, and diseases. This Collection welcomes research that advances our understanding of how these pressures shape pollinator populations, behaviors, communities and the ecosystems they support. We are particularly interested in studies that generate actionable insights for conservation, restoration and policy, including work that evaluates mitigation strategies, models future risks, or examines the effectiveness of current management practices.

Topics of interest include but are not limited to:

• Impacts of pesticide exposure on pollinator health
• How habitat and land‑use changes affect pollinators
• Pollinator biodiversity monitoring
• Pollinator conservation and restoration approaches
• How management practices impact pollinators
• Pollination ecology in changing environments
• Effects of diseases on bee populations
• Climate‑driven shifts in pollinator phenology, distribution and behavior
• Evolutionary responses to environmental stressors, including adaptation, plasticity and genetic change
• Impacts of invasive species on native pollinators and pollination systems
• Landscape connectivity and fragmentation, and their influence on pollinator movement and gene flow
• Neuroethological and behavioral studies linking stressors to changes in cognition, navigation and foraging
• Socio‑ecological and policy‑relevant research that informs conservation planning, agri‑environment schemes and ecosystem‑service management
• Modeling approaches predicting future risks to pollinators or forecasting ecosystem impacts of pollinator decline

All manuscripts submitted to this journal, including those submitted to collections and special issues, are assessed in line with our editorial policies and the journal’s peer review process. Reviewers and editors are required to declare competing interests and can be excluded from the peer review process if a competing interest exists.

BMC Ecology and Evolution welcomes submissions of research exploring the remarkable adaptations and ecological dynamics that enable life to flourish in the dark and low light environments. Contributions will explore evolutionary adaptations such as sensory specialization (e.g., night vision, echolocation, bioluminescence, heat-sensitive pits, and specialized hairs) that allow organisms to navigate, forage, and communicate in low-light conditions from caves to the deep sea. The collection will also investigate behavioral and physiological mechanisms, including circadian rhythm adjustments and predator-prey interactions, that are essential for survival in nocturnal niches.

Submissions on the impact of anthropogenic influences, such as light pollution, on nocturnal ecosystems and biodiversity are encouraged. The Collection also welcomes research on nighttime bioacoustics and soundscapes, examining how sound is used to adapt to and shape nocturnal environments. Contributions discussing the role of citizen science in advancing our understanding of nighttime ecology are also encouraged.
