Figure 5. Bayesian phylogeny, with species divergence age estimates reconstructed with BEAST using all the 26 in Complete mitochondrial genomes from museum specimens clarify millipede evolution in the Eastern Arc Mountains
Figure 5. Bayesian phylogeny, with species divergence age estimates reconstructed with BEAST using all the 26 mitochondrial genomes generated in this study. The dataset was supplemented with Thyropygus sp. and Abacion magnum as outgroups, derived from GenBank. GenBank accession numbers are provided in parentheses. Blue bars indicate the 95% highest probability density intervals for node ages. Age estimation for lineage divergence was based on a general arthropod mitochondrial DNA substitution rate and should be considered with caution. *Thyropygus sp. (red font) is very likely to be a misidentification; for more information, see the Discussion.

Cen-Lup-Cru-Panorama: Centaurus Carrying the Beast and Riding Along the Milky Way
<p>Winner in the 2022 IAU OAE Astrophotography Contest, category Still images of celestial patterns.</p> <p> </p> <p>This image was taken in February 2020 in the Coquimbo Region along the northern coast of Chile. It is one of the best places on Earth for astronomical observations, thanks to its clear skies, lack of light pollution and lack of precipitation, as it is close to the Atacama desert, one of the driest places on our planet. It is no coincidence that many of the most modern professional observatories are located here. The picture shows prominent patterns visible in the southern latitudes, containing rich cultural significance for various Indigenous groups of the southern world. In the bottom of the image towards the right, the Southern Cross is prominent. The orange star at the top of the Southern Cross is called Gacrux (gamma crux). The people in Chile celebrate the beginning of winter at the beginning of May when the constellation Crux is high up in the sky; for them it is a symbol of the start of the cold season. For the festival of the Cruz de Mayo (the Great Cross), they put candles next to crosses in their villages when the constellation Crux is high. As in Christianity, the four endpoints (stars) of the cross symbolise the cardinal virtues. For some indigenous Chileans, they represent the fundamental cultural principles: force, reciprocity, wisdom, and spirituality.</p> <p>Unlike modern constellations that are arrangements of several stars, Indigenous peoples sometimes associate stories with individual stars. In the case of the Southern Cross for example, the Boorong, Djab Wurrung and Jardwadjali peoples of Australia refer to the star Gacrux as Bunya (the ring-tailed possum). From the Southern Cross to the left of the image are two bright stars, these are called the pointer stars (as they point to the Southern Cross). The Djab Wurrung and Jardwadjali people refer to the pointer stars as the Bram-bram-bult brothers, who hunted and killed the giant Emu Tchingal. Alpha Centauri, which is the brighter and whiter of the two pointer stars, is the closest star to the Sun that we can see with our eyes, located just over four light-years away. To the bottom left of the Southern Cross is a dark nebula, which the Indigenous Australians see as the head of the Emu Tchnigal (the Coalsack Nebula). The pointers are located on the neck of the Emu. The image also shows two other IAU constellations, Centaurus (The Centaur) and Lupus (The Wolf), and HII regions of the Eta Carina Nebula (seen in pink).</p> <p>Credit: Uwe Reichert/IAU OAE (<a href="https://creativecommons.org/licenses/by/4.0/legalcode">CC BY 4.0</a>)</p>

Taming the beast: a revised classification of Cortinariaceae based on genomic data
<p>Family <i>Cortinariaceae</i> currently includes only one genus, <i>Cortinarius</i>, which is the largest <i>Agaricales</i> genus, with thousands of species worldwide. The species are important ectomycorrhizal fungi and form associations with many vascular plant genera from tropicals to arctic regions. Genus <i>Cortinarius</i> contains a lot of morphological variation, and its complexity has led many taxonomists to specialize in particular on infrageneric groups. The previous attempts to divide <i>Cortinarius</i> have been shown to be unnatural and the phylogenetic studies done to date have not been able to resolve the higher-level classification of the group above section level. Genomic approaches have revolutionized our view on fungal relationships and provide a way to tackle difficult groups. We used both targeted capture sequencing and shallow whole genome sequencing (WGS) to produce data and to perform phylogenomic analyses of 75 single-copy genes from 19 species. In addition, a wider 5-locus analysis of 245 species, from the Northern and Southern Hemispheres, was also done. Based on our results, a classification of the family <i>Cortinariaceae</i> into ten genera—<i>Cortinarius, Phlegmacium, Thaxterogaster, Calonarius, Aureonarius, Cystinarius, Volvanarius, Hygronarius, Mystinarius, </i>and<i> Austrocortinarius</i>—is proposed. Seven genera, 10 subgenera, and four sections are described as new to science and five subgenera are introduced as new combinations in a new rank. In addition, 41 section names and 514 species names are combined in new genera and four lecto- and epitypes designated. The position of <i>Stephanopus</i> in suborder <i>Agaricineae</i> remains to be studied. Targeted capture sequencing is used for the first time in fungal taxonomy in Basidiomycetes. It provides a cost-efficient way to produce -omics data in species-rich groups. The -omics data was produced from fungarium specimens up to 21 years old, demonstrating the value of museum specimens in the study of the fungal tree of life. This study is the first family revision in Agaricales based on genomics data and hopefully many others will soon follow.</p>
Maximum clade credibility (MCC) tree of Argyrodes lanyuensis from Philippines and Orchid Island Taiwan using BEAST 1.10
<p>Oceanic islands are unique geographic systems that promote local adaptations and allopatric speciation in many of their highly endemic taxa. This is a common case in the Philippine Archipelago, where numerous unrelated taxa on islands have been inferred to have diversified in isolation. However, few cases have been reported in invertebrates especially among parasitic organisms. Here, we tested for biogeographical structure in novel populations of the "generalist" kleptoparasitic spider, <i>Argyrodes lanyuensis </i>Yoshida, Tso & Severinghaus, 1998<span> in the Philippines</span>. Results showed that, in addition to Orchid Island, this species has a wide geographic distribution in the Philippine Archipelago. The estimated divergence time of this lineage using the mitochondrial cytochrome oxidase 1 (mt-CO1) suggests that this species diverged <i>ca</i> 3.12 MYA, during the Pliocene. Two reciprocal monophyletic clades were elucidated in <i>A. lanyuensis</i>, but with limited differentiation across Pleistocene Aggregate Island Complex (PAIC) boundaries and modern-day islands. However, in our analyses of morphological variation, we identified two phenotypically differentiated units in males (Orchid Island, Taiwan+Luzon, Philippine PAIC populations versus Palawan+West Visayan+Mindanao PAIC populations). We infer that this species diverged in the southern portion of the Philippine Archipelago and only recently colonized Orchid Island. Our study provides new information on the extensive distribution of <i>A. lanyuensis</i> outside Orchid Island, Taiwan, but we documented a very limited geographically associated genetic variation. Our study points to behavioral phenomena such as foraging behavior as essential contributor to the evolutionary process of species diversification, in contrast to the traditionally invoked geographic drivers of divergence.</p>
