Biodiversity, from genes to entire ecosystems, is crucial for a healthy planet. However, human activities, including business practices, are causing rapid biodiversity loss. This study focuses on selecting and integrating protection practices into the supply chain, offering chance make positive changes environment future generations. A new hybrid grey multi-criteria decision-making (MCDM) model proposed in this paper, which combines Best–Worst Method (BWM) obtaining criteria weights Axial Distance-based Aggregated Measurement (ADAM) method ranking alternatives (practices). The applicability of solving defined problem was demonstrated by nine according seven criteria. most effective chain management context conservation were policies (with score 0.044), goal setting, monitoring, reporting, transparency (0.039), education awareness raising (0.037). These best because they combine clear frameworks, measurable goals, long-term cultural change conservation. lowest ranked practice compliance with legislation (0.006) since it represents baseline, reactive approach rather than proactive or innovative strategy provides comprehensive framework MCDM that enhances theoretical knowledge can serve as basis developing practical tool integrating, assessing, prioritizing biodiversity-focused chains. main novelties paper extension ADAM environment, development BWM method, identification biodiversity-oriented strategies chains their evaluation, evaluation selection.

Species diversity underpins all ecosystem services that support life. Despite this recognition and the great advances in detecting biodiversity, exactly how many which species co-occur interact, directly or indirectly any is unknown. Biodiversity accounts are incomplete; taxonomically, size, habitat, mobility rarity biased. In ocean, provisioning of fish, invertebrates algae a fundamental service. This extracted biomass depends on myriad microscopic macroscopic organisms make up fabric nature affected by management actions. Monitoring them attributing changes to policies daunting. Here we propose dynamic quantitative models interactions can be used link policy compliance with complex ecological networks. allows managers qualitatively identify 'interaction-indicator' species, highly impacted through propagation interactions.

Abstract Climate change is negatively impacting ecosystems and their contributions to human well‐being, known as ecosystem services. Previous research has mainly focused on the direct effects of climate species services, leaving a gap in understanding indirect impacts resulting from changes interactions within complex ecosystems. This knowledge significant because loss food web can lead additional losses or “co‐extinctions,” particularly when most impacted by are also that play critical roles persistence provide Here, we present framework investigate relationships among vulnerability change, web, overall these systems services face climate‐induced losses. To do this, assess robustness webs associated climate‐driven extinctions eight empirical rocky intertidal webs. Across webs, find highly connected not vulnerable change. However, directly more than which results service provision collapsing before Overall, robust they show combining with offer predictions about co‐extinctions for future persistence. conclusions limited data availability quality, underscoring need comprehensive collection linking interaction networks vulnerabilities
