“…En ese sentido, la secuenciación genética nos da la posibilidad de estimar su abundancia, lo que, a su vez, nos permitiría evaluar de manera más precisa su impacto en términos de biomasa. Adicionalmente, las ciencias ómicas han permitido tener los primeros avances sobre su ciclo de vida y el impacto que podrían ocasionar, así como comprender los cambios evolutivos a consecuencia de los cambios de clima en la region (Garcia-Lopez et al, 2022;Hotaling, Price y Hamilton, 2022).…”

Snow is a critical component of the Earth system. High elevation snow can persist into the spring, summer and early fall and hosts a diverse array of life including snow algae. Due in part to the presence of pigments, snow algae lower albedo and accelerate snow melt which has led to increasing interest in identifying and quantifying the environmental factors that constrain their distribution. Dissolved inorganic carbon (DIC) concentration is low in supraglacial snow on Cascade stratovolcanoes and snow algae primary productivity can be stimulated through DIC addition. Here we asked if inorganic carbon would be a limiting nutrient for snow hosted on glacially eroded carbonate bedrock which could provide an additional source of DIC. We assayed snow algae communities for nutrient and DIC limitation on two seasonal snowfields on glacially eroded carbonate bedrock in the Snowy Range of the Medicine Bow Mountains, Wyoming, USA. DIC stimulated snow algae primary productivity in snow with lower DIC concentration despite the presence of carbonate bedrock. Our results support the hypothesis that increased atmospheric CO2 concentrations may lead to larger and more robust snow algae blooms globally, even for sites with carbonate bedrock.
