Fern and Epiphyte Biology
Fern and Epiphyte Biology is a research topic within Ecology, Evolution, Behavior and Systematics. Science Explorer counts 13k research works in it since 1950. 19.8% of them reached the world's top 10% most cited for their field and year.
This cluster of papers explores the evolution, diversity, and ecological significance of vascular epiphytes and ferns, with a focus on phylogeny, adaptive radiation, biogeography, and ecological strategies. It delves into the relationships between epiphytes and their host trees, the impact of climate change on canopy communities, and the physiological ecology of vascular epiphytes. The cluster also addresses topics such as polyploidy, gametophyte ecology, and the morphological evolution of ferns.

How concentrated that is
The same countries as shares of everything the list above accounts for. A node where two countries do two thirds of the work and one spread evenly across twelve read alike as a ranking and not at all alike here.
