Conservation applications of niche modeling: Native and naturalized ferns may compete for limited Hawaiian dryland habitat. [PDF]

Appl Plant Sci
Abstract Premise Competition from naturalized species and habitat loss are common threats to native biodiversity and may act synergistically to increase competition for decreasing habitat availability. We use Hawaiian dryland ferns as a model for the interactions between land‐use change and competition from naturalized species in determining habitat ...

Was the Dry Diagonal of South America a Barrier for Dispersing Pteridaceae (Polypodiopsida) Species Between the Brazilian Atlantic Forest and Amazon Forest?

Journal of Biogeography, Volume 52, Issue 8, August 2025.
ABSTRACT Aim We sought to assess how phylogenetic patterns within the fern family Pteridaceae are related to the history of the Amazon Forest and the Brazilian Atlantic Forest, as well as the Dry Diagonal of South America. The age of taxa present in these regions was estimated, as well as those found in previously identified areas of endemism for the ...
