Glacier and permafrost shrinkage land-use intensification threaten mountain wildlife affect nature conservation strategies. Here, we present paleometagenomic records of terrestrial aquatic taxa from the southeastern Tibetan Plateau covering last 18,000 years to help understand complex alpine ecosystem dynamics. We infer that steppe-meadow became woodland at 14 ka (cal BP) controlled by cryosphere loss, further driving a herbivore change wild yak deer. These findings weaken hypothesis top-down control large herbivores in ecosystem. find turnover communities ka, transitioning glacier-related (blue-green) algae abundant nonglacier-preferring picocyanobacteria, macrophytes, fish, otters. There is no evidence for substantial effects livestock herding either Using network analysis, assess stress-gradient reveal root hemiparasitic cushion plants are keystone taxa. With ongoing protection their habitats likely be benefit on Plateau.

The Ecology and Evolution of Model Microbial Mutualisms

Annual Review of Ecology Evolution and Systematics, Journal Year: 2021, Volume and Issue: 52(1), P. 363 - 384

Published: Aug. 31, 2021

Mutually beneficial interspecific interactions are abundant throughout the natural world, including between microbes. Mutualisms microbes critical for everything from human health to global nutrient cycling. Studying model microbial mutualisms in laboratory enables highly controlled experiments developing and testing evolutionary ecological hypotheses. In this review, we begin by describing tools available studying mutualisms. We then outline recent insights that systems have shed on origins, dynamics, features of mutualism. touch gaps our current understanding mutualisms, note connections mutualism nonmicrobial systems, call attention open questions ripe future study.
