New Perspective!🔥It's fascinating how scientists from different fields but interested in the same question [e.g. genotype-phenoytpe relationship] can have such different perspectives. Here we put in our 2 cents wrt genetic effects being context-dependent, and pheno variation being mostly polygenic

An analysis of forest plant traits from across the tropical Americas suggests that forests are not changing fast enough to keep up with #ClimateChange. Learn more in this week's issue of Science: scim.ag/3QLYhyc
In Mesoamerican cloud forests, such as this one in the El Triunfo Biosphere Reserve in Mexico, climate change and deforestation are leading to plant species moving upslope. However, an analysis of forest plant traits from across the tropical Americas suggests that forests are not changing fast enough to keep up with climate change.
