Yet the true diversity, uniqueness, and vulnerability of its soil communities are only beginning to be revealed. As tourism and science expeditions bring ever more passengers and cargo to Antarctica, human-induced transport of species (\u2018biological invasion\u2019) \u2013 both into and throughout the region \u2013 presents a growing threat to soil biodiversity, as highlighted recently in <span><a href=\"https:\/\/doi.org\/10.1111\/eva.12913\" target=\"_blank\" rel=\"noopener noreferrer\">our study<\/a><\/span>.<\/p>[\/et_pb_text][et_pb_image src=&#8221;https:\/\/ibol.org\/barcodebulletin\/wp-content\/uploads\/2020\/06\/Baird_Figure1.jpg&#8221; title_text=&#8221;Baird_Figure1&#8243; _builder_version=&#8221;4.4.7&#8243;][\/et_pb_image][et_pb_text _builder_version=&#8221;4.4.7&#8243; text_font=&#8221;||||||||&#8221; text_text_color=&#8221;#646564&#8243; text_font_size=&#8221;16px&#8221;]The Antarctic terrestrial biome near McMurdo station.\n<span style=\"font-size: 90%;\">PHOTO CREDIT: Helena Baird<\/span>[\/et_pb_text][et_pb_text _builder_version=&#8221;4.4.7&#8243;]<p>In the Antarctic region, which broadly covers approximately 30% of the planet\u2019s surface, soil organisms represent the vast majority of terrestrial life. Antarctic soil organisms, which include nematodes, mites, springtails, fungi, and tardigrades, have eked out a largely isolated existence over millions of years in fragmented patches of ice-free land on the continent, or on the sub-Antarctic islands.<\/p>\n<p>On the Antarctic continent, ice-free soil represents &lt;1% of the total land area and can be found on mountain tops, scree slopes, valleys, and the coast. The sub-Antarctic islands encircle the continent, located in the frigid waters of the Southern Ocean and each is separated by up to thousands of kilometres of open ocean. Antarctic soil species are therefore highly isolated and possess unique adaptations to their harsh environment. They are at risk of being outcompeted, or ultimately even replaced, by invasive species as the climate warms<sup>2<\/sup>.<\/p>[\/et_pb_text][baie_before_after_image src_before=&#8221;https:\/\/ibol.org\/barcodebulletin\/wp-content\/uploads\/2020\/06\/Baird_Figure2-e1591234254319.jpg&#8221; label_before=&#8221; &#8221; src_after=&#8221;https:\/\/ibol.org\/barcodebulletin\/wp-content\/uploads\/2020\/06\/Baird_Figure3-e1591233804906.jpg&#8221; label_after=&#8221; &#8221; title_text=&#8221;Baird_Figure2&#8243; size=&#8221;fullsize.&#8221; slider_offset=&#8221;65%&#8221; align=&#8221;center&#8221; force_fullwidth=&#8221;on&#8221; _builder_version=&#8221;4.4.7&#8243;][\/baie_before_after_image][et_pb_text _builder_version=&#8221;4.4.7&#8243; text_font=&#8221;||||||||&#8221; text_text_color=&#8221;#646564&#8243; text_font_size=&#8221;16px&#8221; max_width=&#8221;80%&#8221; module_alignment=&#8221;center&#8221;]<p>LEFT: Helena Baird and colleagues busy with sub-Antarctic fieldwork on Marion Island while king penguins watch in the background.

Identification of numerous divergent barcode sequences revealed that the invasive has been introduced to Antarctica several times.<\/p>\n<p>By comparing barcodes from Antarctic specimens in BOLD to those found elsewhere in the world, we could identify genetic lineages shared across countries which aligned with known shipping routes to the Southern Ocean, highlighting the utility of molecular tools in tracking invasion. For example, a shared barcode haplotype between Norway and the sub-Antarctic island of South Georgia accords directly with Norway\u2019s long history of whaling on this island. That a well-known invasive species has been introduced on multiple occasions to such a remote region emphasises the importance of ongoing biosecurity monitoring, even for invasive species that have already established, since multiple invasions can introduce more genetic resilience and enable the invasive species to spread.<\/p>[\/et_pb_text][et_pb_image src=&#8221;https:\/\/ibol.org\/barcodebulletin\/wp-content\/uploads\/2020\/06\/Baird_Figure5.jpg&#8221; title_text=&#8221;Baird_Figure5&#8243; _builder_version=&#8221;4.4.7&#8243;][\/et_pb_image][et_pb_text _builder_version=&#8221;4.4.7&#8243; text_font=&#8221;||||||||&#8221; text_text_color=&#8221;#646564&#8243; text_font_size=&#8221;16px&#8221;]Research vessel as it approaches Possession island, Crozet archipelago, one of the sub-Antarctic islands in the region.\n<span style=\"font-size: 90%;\">PHOTO CREDIT: Helena Baird<\/span>[\/et_pb_text][et_pb_image src=&#8221;https:\/\/ibol.org\/barcodebulletin\/wp-content\/uploads\/2020\/06\/Baird_Figure4.jpg&#8221; title_text=&#8221;Baird_Figure4&#8243; _builder_version=&#8221;4.4.7&#8243;][\/et_pb_image][et_pb_text _builder_version=&#8221;4.4.7&#8243; text_font=&#8221;||||||||&#8221; text_text_color=&#8221;#646564&#8243; text_font_size=&#8221;16px&#8221;]<p>Charlene Janion-Scheepers (left) and Helena Baird (right) sort soil species at sea using Berlese funnels.<br \/> <span style=\"font-size: 90%;\">PHOTO CREDIT: Steven Chown<\/span><\/p>[\/et_pb_text][et_pb_text _builder_version=&#8221;4.4.7&#8243;]<p>Our study also explored the consequences of intra-regional human transport on native soil species. Antarctic soil organisms are typically highly endemic, even to local patches within the region. This raises the concern that increased human traffic throughout Antarctica could transport and ultimately homogenise soil populations, altering the region\u2019s unique biogeography. Using genome-wide SNPs, we showed that a widespread native springtail species is indeed so distinct between sub-Antarctic islands that it is likely in the process of speciating. Clearly, future exchange of individuals among islands could possibly disrupt this biodiversity process, diluting the specific adaptations each population has evolved over millennia. Potential evolutionary consequences include a decrease in the fitness of island-specific populations, lineage extinction, or the loss of biodiversity by \u2018reverse speciation\u2019<sup>3<\/sup>.<\/p>\n<p>Regardless of the outcome, the threat of disrupting biodiversity processes among these unique and fragile islands emphasises the importance of biosecurity for ships travelling throughout the Southern Ocean, particularly when passengers embark and disembark at multiple locations.<\/p>[\/et_pb_text][et_pb_image src=&#8221;https:\/\/ibol.org\/barcodebulletin\/wp-content\/uploads\/2020\/06\/Baird_Figure6.jpg&#8221; title_text=&#8221;Baird_Figure6&#8243; _builder_version=&#8221;4.4.7&#8243;][\/et_pb_image][et_pb_text _builder_version=&#8221;4.4.7&#8243; text_font=&#8221;||||||||&#8221; text_text_color=&#8221;#646564&#8243; text_font_size=&#8221;16px&#8221;]Taking a break to enjoy the view in the sub-Antarctic.\n<span style=\"font-size: 90%;\">PHOTO CREDIT: Helena Baird<\/span>[\/et_pb_text][et_pb_text _builder_version=&#8221;4.4.7&#8243;]<p>One of the main hurdles to accurately predicting future changes to soil communities is a lack of basic biodiversity knowledge.
