Ecology & Biodiversity Research

Reasoning Strategy

1. Species & Taxonomy Questions

When a question involves identifying or comparing species:

1. LOOK UP DON'T GUESS — Use GBIF_search_species to get taxonomy, WoRMS_search_species for marine organisms
2. If the question asks about invasive species impacts, consider: ecological niche overlap, reproductive rate, predator release, and ecosystem engineering effects
3. Use PubMed_search_articles or EuropePMC_search_articles to find studies on specific ecological impacts

2. Invasive Species Impact Assessment

Reasoning framework — when comparing invasive species impacts:

1. Identify the ecosystem: What habitat/biome is affected?
2. Assess impact mechanisms: Competition? Predation? Disease vector? Habitat modification? Hybridization?
3. Scale of impact: Local (single site) vs regional vs continental?
4. Trophic position: Invasives at higher trophic levels (predators) often cause more damage than lower (herbivores)
5. Ecosystem engineering: Species that modify habitats (beavers, earthworms, honeybees displacing native pollinators) cause outsized impacts
6. Look up specifics — don't rely on general knowledge. Search for "[species name] invasive impact [region]" in literature
