GOALS<\/h2>\n

[\/vc_column_text][vc_separator type=”transparent” thickness=”15″][vc_column_text css=””]<\/i><\/span>To assess the biodiversity of green algae<\/strong> in representative mountain environments in the Alps<\/strong><\/a>, including pioneer areas opened by glaciers\u2019 retreat and snow cover, using environmental DNA.<\/p>\n

<\/i><\/span>To isolate and purify living strains of green algae<\/strong> for genomic, taxonomic, biological and ecophysiological characterization, in relation to high altitude environmental parameters.<\/p>\n

<\/i><\/span>To characterize the acclimation and adaptation strategies of green algae to high altitude environments.<\/strong><\/p>\n

<\/i><\/span>To characterize the dynamics<\/strong> of green algae in snow and identify the parameters to take into account in climate models<\/strong>.[\/vc_column_text][\/vc_column][\/vc_row][vc_row css_animation=”” row_type=”row” use_row_as_full_screen_section=”no” type=”grid” angled_section=”no” text_align=”left” background_image_as_pattern=”without_pattern” padding_top=”36″ padding_bottom=”24″ z_index=”” css=”.vc_custom_1613561230136{background-color: #ededed !important;}”][vc_column width=”1\/2″][vc_separator type=”transparent” thickness=”30″][vc_column_text]<\/p>\n

FIELD CAMPAIGNS<\/h2>\n

[\/vc_column_text][vc_separator type=”transparent” thickness=”15″][vc_column_text css=””]Field campaigns are carried out with the support of the Lautaret Garden (Jardin du Lautaret<\/strong><\/a>). They have been initiated in May-June 2017, on several selected sites including Vallon Roches Noires<\/strong><\/a> (from 1,900 to 2,800 meters above sea level), the Cerces-La Bruy\u00e8re<\/strong> sector and the Ecrins National Park<\/strong> (from 2,200 to 3,200 meters above sea level). In addition, the studies carried out within the framework of the ALPALGA project can benefit from sampling performed in other contexts, including the ORCHAMP<\/strong><\/a> project, on the sites of Chamrousse, Anterne, Loriaz, Vieux-Chaillol and Ristolas (from 1,200 to 3,000 meters above sea level). From 2017 to 2025, ALPALGA has increased its exploration to Mont Br\u00e9vent<\/strong>, close to Chamonix, Glacier de Saint Sorlin<\/strong>, and other locations in the French Alps<\/strong>. In 2022, field studies were performed on Mount Olympus<\/strong>, in Greece<\/strong>.<\/p>\n

In addition, two field campaigns were conducted in 2023 and 2024 in the Scoresby Fjord<\/strong>, in Greenland<\/strong>, with the help of GREENLANDIA<\/strong><\/a>.[\/vc_column_text][vc_separator type=”transparent” thickness=”30″][\/vc_column][vc_column width=”1\/2″][vc_single_image image=”15875″ img_size=”large” qode_css_animation=””][\/vc_column][\/vc_row][vc_row css_animation=”” row_type=”row” use_row_as_full_screen_section=”no” type=”grid” angled_section=”no” text_align=”left” background_image_as_pattern=”without_pattern” padding_top=”36″ padding_bottom=”24″ z_index=””][vc_column width=”1\/2″][vc_single_image image=”15648″ img_size=”large” qode_css_animation=””][\/vc_column][vc_column width=”1\/2″][vc_separator type=”transparent” thickness=”30″][vc_column_text]<\/p>\n

EXPLORING BIODIVERSITY<\/h2>\n

[\/vc_column_text][vc_separator type=”transparent” thickness=”15″][vc_column_text css=””]The exploration of biodiversity is achieved through the study of environmental DNA, carried out by the Laboratory of Alpine Ecology<\/a><\/strong>, using the metabarcoding and metagenomics methods.[\/vc_column_text][vc_separator type=”transparent” thickness=”30″][\/vc_column][\/vc_row][vc_row css_animation=”” row_type=”row” use_row_as_full_screen_section=”no” type=”grid” angled_section=”no” text_align=”left” background_image_as_pattern=”without_pattern” padding_top=”36″ padding_bottom=”24″ z_index=”” css=”.vc_custom_1613561258320{background-color: #ededed !important;}”][vc_column width=”1\/2″][vc_separator type=”transparent” thickness=”30″][vc_column_text]<\/p>\n
