We studied biogeographic patterns of Antarctic freshwater diatoms based on the analysis of species occurrences in a dataset of 439 lakes spread across the Antarctic realm. Highly distinct diatom floras, both in terms of composition and richness, characterize Continental Antarctica, Maritime Antarctica and the sub-Antarctic islands, with marked biogeographic provincialism in each region. A total of 44% of all species is estimated to be endemic to the Antarctic, and most of them are confined to a single biogeographic region. The level of endemism significantly increases with increasing latitude and geographic isolation. Our results have implications for conservation planning, and suggest that successful dispersal of freshwater diatoms to and within the Antarctic is limited, fostering the evolution of highly endemic diatom floras.&lt;/p&gt;</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Tyler J.

While long-term ecological change is commonly evaluated through sediment cores in lakes, it is generally not feasible for smaller ponds, and spatial resolution is limited. Here, we analyze pond diatom communities collected during Shackleton&amp;#39;s &lt;em&gt;Nimrod&lt;/em&gt; expedition at Cape Royds, Antarctica, to compare with the same waterbodies a century later. We find historical samples to be almost identical to modern counterparts, and provide no evidence of exotic introductions despite increasing human activity. However, a shift occurred in the pond nearest Shackleton&amp;#39;s hut, Pony Lake, which was dominated by &lt;em&gt;Luticola muticopsis&lt;/em&gt; a century ago, and was replaced by &lt;em&gt;Craspedostauros laevissimus&lt;/em&gt;. Both are endemic species previously and currently present at Cape Royds, and we hypothesize that a shift in conductivity accompanying changing precipitation patterns may be responsible. Collectively, these results provide important data for assessing human and climate impacts among Antarctic lacustrine habitats.&lt;/p&gt;</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Bishop, Jordan</style></author><author><style face="normal" font="default" size="100%">Kopalová, Kateřina</style></author><author><style face="normal" font="default" size="100%">Darling, Joshua P.</style></author><author><style face="normal" font="default" size="100%">Schulte, Nicholas O.</style></author><author><style face="normal" font="default" size="100%">Tyler J.

One of these taxa, &lt;em&gt;Navicula adminensis&lt;/em&gt; D.Roberts &amp;amp; McMinn, was described from the Vestfold Hills, East Antarctica. Detailed light and scanning electron microscopy observations have shown that based on its morphological features, the species does not belong to the genus &lt;em&gt;Navicula sensu stricto&lt;/em&gt;. To determine the most closely related genera to &lt;em&gt;N. adminensis&lt;/em&gt;, the morpho- logical features of &lt;em&gt;Adlafia&lt;/em&gt;, &lt;em&gt;Kobayasiella&lt;/em&gt;, &lt;em&gt;Envekadea&lt;/em&gt;, &lt;em&gt;Stenoneis&lt;/em&gt;, &lt;em&gt;Berkeleya&lt;/em&gt;, &lt;em&gt;Climaconeis&lt;/em&gt;, and &lt;em&gt;Parlibellus&lt;/em&gt; were compared with those of &lt;em&gt;N. adminensis&lt;/em&gt;. Although each of these genera shows one or more similar features, none of them accommodates the salient morphological characteristics of N. adminensis. Therefore, a new genus, &lt;em&gt;Sabbea gen. nov.&lt;/em&gt;, is herein described, and &lt;em&gt;Navicula adminensis&lt;/em&gt; is formally transferred to the new genus as &lt;em&gt;Sabbea adminensis comb. nov.&lt;/em&gt; The genus &lt;em&gt;Sabbea&lt;/em&gt; is characterized by uniseriate striae composed of small, rounded areolae occluded externally by individual hymenes, a rather simple raphe structure with straight, short proximal ends and short terminal raphe fissures, open girdle bands with double perforation and a very shallow mantle.&lt;/p&gt;</style></abstract><issue><style face="normal" font="default" size="100%">1</style></issue></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Tyler J.
