de Deus Vidal, J., P. C. le Roux, S. D. Johnson, M. te Beest, and V. R. Clark. 2021. Beyond the Tree-Line: The C3-C4 “Grass-Line” Can Track Global Change in the World’s Grassy Mountain Systems. Frontiers in Ecology and Evolution 9. https://doi.org/10.3389/fevo.2021.760118

von Humboldt’s tree-line concept has dominated mountain ecology for almost two hundred years, and is considered a key indicator for monitoring change in biome boundaries and biodiversity shifts under climate change. Even though the concept of life zones and elevation gradients are a globally observe…

TREVIÑO-ZEVALLOS, I., I. GARCÍA-CUNCHILLOS, and C. LADO. 2021. New records of Myxomycetes (Amoebozoa) from the tropical Andes. Phytotaxa 522: 231–239. https://doi.org/10.11646/phytotaxa.522.3.6

The Myxomycetes comprise a remarkably diverse group of organisms within Amoebozoa, with over 1000 species currently recognized. These organisms, at the end of their life cycles produce fruiting bodies which are the basis for their systematics. Despite being a biodiversity hotspot, the tropical Andes…
