Valentina Cevallos

Valentina helps learners move from naming species to explaining ecological patterns. Her lessons connect isolation, adaptation, food webs, disturbance, invasive species, sampling limits, human choices, and the evidence behind conservation claims.

Valentina's lessons focus on Biodiversity, evolution, island biogeography, coastal ecology, conservation evidence, invasive species, field sampling, species interactions, and science communication. Sessions are designed for curious teens, university learners, educators, travellers, conservation volunteers, and nature enthusiasts and usually use food webs, island models, field-sampling plans, species-interaction maps, evidence comparisons, observation logs, and conservation scenarios.

Valentina teaches biodiversity and island ecology through evolution, species interactions, field methods, coastal systems, conservation evidence, and clear science communication. The teaching approach combines field-science curiosity, visual ecosystem maps, evidence comparison, warm questioning, and conservation context.

A useful place to begin: Bring an organism, island, ecosystem, or conservation claim. We will map the interactions, identify the evidence, and find the question a field study could answer.
