Using a field-based proof-of-concept experiment, we demonstrated that subsurface snow algae absorb significant energy across various wavelengths, challenging previous assumptions that focused only on visible blooms. These findings suggest that the contribution of snow algae to cryosphere melt may be underestimated, with implications for predicting snowmelt and managing water resources. By shedding light on the energy-absorbing capacity of subsurface algae, this research emphasizes the need for further exploration of their ecological and hydrological impacts.<br /></strong><strong>&#8203;</strong><br />Nuestro &uacute;ltimo estudio explora el papel de las algas de nieve subsuperficiales en la reducci&oacute;n de la reflectancia de la nieve (albedo), incluso cuando est&aacute;n cubiertas por una capa de nieve. Utilizando un experimento de campo tipo prueba de concepto, demostramos que estas algas absorben una cantidad significativa de energ&iacute;a en diferentes longitudes de onda, desafiando las suposiciones previas que solo consideraban los <em>blooms</em> visibles.&nbsp;Los resultados destacan la importancia, hasta ahora subestimada, de las algas de nieve en el derretimiento de la criosfera, con implicaciones clave para la predicci&oacute;n del deshielo y la gesti&oacute;n de los recursos h&iacute;dricos.

This has resulted in increased atmospheric nitrogen deposition worldwide, with significant impacts on ecosystems, which may be more pronounced in nutrient-poor environments like the alpine ecosystem. In our recent study, we investigated how snow algae respond to varying concentrations of nitrogen (N) and phosphorus (P), two key nutrients in the ecosystems. Through laboratory experiments, we found that these microalgae can thrive across a wide range of N and P conditions. However, our results highlight a particularly high P requirement for optimal growth. This suggests that increased N deposition alone may have a limited effect on the frequency and extent of these blooms, challenging previous assumptions.<br /></strong><br /><span></span>&#8203;El cambio global ha alterado los ciclos de nutrientes, impulsado en gran medida por la combusti&oacute;n de combustibles f&oacute;siles y el uso excesivo de fertilizantes en la agricultura. Esto ha resultado en un aumento de la deposici&oacute;n atmosf&eacute;rica de nitr&oacute;geno a nivel mundial, con impactos significativos en los ecosistemas, que pueden ser m&aacute;s pronunciados en ambientes pobres en nutrientes, como el ecosistema alpino. En nuestro estudio reciente, investigamos c&oacute;mo responden las algas de la nieve a diferentes concentraciones de nitr&oacute;geno (N) y f&oacute;sforo (P), dos nutrientes clave en los ecosistemas. A trav&eacute;s de experimentos de laboratorio, descubrimos que estas microalgas pueden prosperar en un amplio rango de condiciones de N y P. Sin embargo, nuestros resultados destacan una necesidad particularmente alta de P para un crecimiento &oacute;ptimo. Esto sugiere que el aumento de la deposici&oacute;n de N por s&iacute; solo puede tener un efecto limitado en la frecuencia y extensi&oacute;n de estas floraciones, lo que desaf&iacute;a las suposiciones anteriores.<br /><span style="font-size: 16px; background-color: transparent;"></span><br /><span></span></div>  <div><div class="wsite-image wsite-image-border-none " style="padding-top:10px;padding-bottom:10px;margin-left:0px;margin-right:10px;text-align:right"> <a> <img src="http://www.the-fringe-lab.com/uploads/3/7/8/6/37860273/emi470052-toc-0001-m_orig.jpg" alt="Picture" style="width:auto;max-width:100%" /> </a> <div style="display:block;font-size:90%"></div> </div></div>  <div class="paragraph">&#8203;<span>Find out more details in the&nbsp;</span><a href="https://enviromicro-journals.onlinelibrary.wiley.com/doi/pdf/10.1111/1758-2229.70052" target="_blank">article</a><span>,&nbsp;&#8203;and listen to an AI-generated podcast summarizing the key findings!<br />&#8203;</span></div>  <div title="Audio: nitrogen_and_phosphorus_limitation_of_snow_algae_blooms.wav" class="wsite-html5audio"><audio id="audio_555818151939397846" style="height: auto;" class="wsite-mejs-align-left wsite-mejs-dark" src="http://www.the-fringe-lab.com/uploads/3/7/8/6/37860273/nitrogen_and_phosphorus_limitation_of_snow_algae_blooms.wav" preload="none" data-autostart="no" data-artist="" data-track=""></audio></div>]]></content:encoded></item></channel></rss>
