Climatic niches play a pivotal role in shaping global and regional patterns of species distribution. Tropical rainforests, renowned for their biodiversity and high levels of endemism, are among the most endangered biomes on the planet. In Honduras, which has over 8,000 vascular plant species, 595 of them are orchids. This study represents the first analysis of how future climate projections (RCP2.6 and RCP8.5) could impact the...

Ferns and lycophytes are excellent model organisms to investigate the effect of climate change on species niches, due to their high sensitivity to changes in temperature and precipitation. In Honduras, this species group is particularly diverse with over 713 known taxa. However, we currently lack a quantitative assessment of the impact that changes in climate might have on these species. This study aimed (1) to explore the str...
