Biodiversity & Ecosystem Services: The Living Foundation

Ecosystem services are the benefits people obtain from ecosystems. The Millennium Ecosystem Assessment categorized them into four types: provisioning services (food, fibre, water, genetic resources), regulating services (climate regulation, water purification, pollination, pest control), cultural services (recreation, aesthetic, spiritual, educational), and supporting services (nutrient cycling, soil formation, primary production). These services underpin human well-being and economic activity, yet are often unpriced and consequently undervalued in decision-making.

The flow of ecosystem services depends on biodiversity — the variety of genes, species, communities, and ecosystems. Research over the past three decades has shown that biodiversity is not merely a co-benefit of conservation but a determinant of ecosystem function. More diverse ecosystems tend to be more productive, more stable, and more resilient to disturbance. The mechanisms include complementarity (different species use resources differently, enabling more complete resource use) and selection (more diverse communities are more likely to contain high-performing species).

Hrisana Journal welcomes submissions on all aspects of biodiversity and ecosystem services — from fundamental biodiversity-ecosystem function research through ecosystem service assessment, valuation, and management. Our interdisciplinary scope spans the ecological, biogeochemical, social, and economic dimensions of ecosystem services.

Pollination is one of the most economically valuable regulating services, with global crop pollination valued at hundreds of billions of dollars annually. Animal pollinators — primarily bees but also flies, butterflies, moths, birds, and bats — pollinate over 75% of the world's flowering plant species and about 35% of food crops. Pollinator declines, driven by habitat loss, pesticide use, pathogens, and climate change, threaten this service. Research on pollinator biology, pollinator habitat restoration, and the microbiome of pollinators (particularly for managed honey bees) supports conservation efforts.

Water purification by ecosystems — particularly wetlands, riparian zones, and forests — removes nutrients, sediments, and some pollutants from water. The biological processes include microbial denitrification, plant nutrient uptake, sediment trapping by vegetation, and microbial degradation of organic pollutants. Constructed treatment wetlands, discussed elsewhere in this hub, harness these processes for engineered water treatment. Natural ecosystems providing water purification services are increasingly recognized in watershed management and payment for ecosystem service schemes.

Carbon storage in ecosystems — particularly forests, soils, and coastal blue carbon ecosystems (mangroves, salt marshes, seagrass beds) — is a critical climate regulation service. The biological processes involve photosynthetic carbon fixation, allocation of carbon to biomass and soils, and stabilization of soil carbon through microbial and chemical processes. Enhancing ecosystem carbon storage through restoration, improved management, and protection of existing carbon stocks is among the most readily deployable biological climate mitigation approaches. The microbial ecology of soil carbon stabilization is an active research frontier.

Soil fertility — the capacity of soil to support plant growth — depends on biological processes including organic matter decomposition, nutrient mineralization, nitrogen fixation, and mycorrhizal symbiosis. The soil microbiome is the engine of these processes, with billions of microorganisms in each gram of healthy soil driving the cycling of carbon, nitrogen, phosphorus, sulfur, and other elements. Intensive agricultural practices — tillage, monoculture, synthetic inputs — can degrade soil biological function, reducing fertility and increasing reliance on external inputs.

Nitrogen fixation — the conversion of atmospheric N₂ to ammonia — is performed by bacteria and archaea possessing the nitrogenase enzyme. Symbiotic nitrogen fixation in legumes (Rhizobium, Bradyrhizobium, etc.) provides 100-300 kg N/ha/year in well-nodulated crops, displacing synthetic fertilizer. Associative and free-living nitrogen fixers contribute smaller but still significant amounts. Enhancement of biological nitrogen fixation — through inoculation, crop rotation, and microbiome management — reduces the energy and climate costs of synthetic nitrogen fertilizer, which consumes about 1-2% of global energy use.

Mycorrhizal symbiosis — the association between fungi and plant roots — extends the effective root system of plants, improving uptake of water, phosphorus, and other nutrients. Arbuscular mycorrhizal fungi associate with most crop plants; ectomycorrhizal fungi associate with many trees. Management of mycorrhizal communities through reduced tillage, cover cropping, and inoculation can enhance nutrient uptake, drought tolerance, and soil structure. The functional ecology of mycorrhizal communities and their response to management is an active research area.

Measuring ecosystem services — quantifying the flow of benefits from ecosystems to people — is essential for informed decision-making. Biophysical measurement tracks the underlying ecological processes (e.g., tonnes of carbon sequestered, cubic metres of water purified, number of pollinator visits). Economic valuation translates these flows into monetary values, enabling comparison with marketed goods and services. Both approaches have strengths and limitations, and integrated assessment is often most informative.

Environmental DNA (eDNA) and other molecular tools are transforming biodiversity monitoring, providing more comprehensive and less invasive measures of species presence and abundance. Remote sensing tracks ecosystem extent and condition at landscape to global scales. Process-based models simulate ecosystem function and predict service flows under different management scenarios. These tools, combined with ground-based monitoring, enable increasingly comprehensive ecosystem service assessment.

Economic valuation methods include market pricing (for provisioning services with market prices), revealed preference (e.g., travel cost method for cultural services), stated preference (contingent valuation for non-use values), and benefit transfer (adapting values from other sites). Each method has assumptions and limitations, and the choice depends on the service, the context, and the decision being informed. Payment for ecosystem service schemes — where beneficiaries of services pay those whose management affects service provision — operationalize economic valuation in conservation.

Biotechnology contributes to ecosystem service research and management in several ways. Molecular tools (eDNA, metagenomics, environmental RNA) provide more comprehensive measures of biodiversity and ecosystem function than traditional approaches. Microbiome manipulation can enhance specific services (e.g., inoculation with mycorrhizal fungi for plant establishment, denitrifying bacteria for nitrogen removal in wetlands). Bioremediation restores ecosystem function in contaminated systems. Synthetic biology approaches are being explored for specific challenges, such as engineering microbes to detect environmental stress or to deliver targeted interventions.

The integration of biotechnology with ecosystem service science raises both opportunities and questions. The potential for more precise, less invasive monitoring and for targeted enhancement of specific services is significant. At the same time, the ecological implications of interventions must be carefully assessed, and the social and ethical dimensions of biotech-enabled ecosystem management must be openly discussed. Hrisana Journal welcomes submissions that engage with these dimensions alongside the technical research.
