The article focuses on the Ocmulgee National Monument in Georgia, detailing its historical significance and archaeological findings. Topics include the ancient cultures that inhabited the region for over 12,000 years, the similarities between Ocmulgee and the Cahokia site, and the impact of modern development on the preservation of these mounds and earthworks.

Morabine grasshoppers in the Vandiemenella viatica species group, which show karyotype diversity, have been studied for their ecological distribution and speciation in relation to their genetic and chromosomal diversity. They are good models for studying sex chromosome evolution as "old" and newly emerged sex chromosomes co-exist within the group. Here we present a reference genome for the viatica19 chromosomal race, that possesses the ancestral karyotype within the group. Using PacBio HiFi and Hi-C sequencing, we generated a chromosome-level assembly of 4.09 Gb in span, scaffold N50 of 429 Mb, and complete BUSCO score of 98.1%, containing 10 pseudo-chromosomes. We provide Illumina datasets of males and females, used to identify the X chromosome. The assembly contains 19,034 predicted protein-coding genes, and a total of 75.21% of repetitive DNA sequences. By leveraging HiFi reads, we mapped the genome-wide distribution of methylated bases (5mC and 6 mA). This comprehensive assembly offers a robust reference for morabine grasshoppers and supports further research into speciation and sex chromosome diversification within the group and its related species.

Winnicott's paper, "Playing, Creativity, and the Search for the Self," Chapter 4 of Playing and Reality is the second leg of Winnicott's two-part opus on play. It is the focus of Smadar Steinbock's essay on temporality in the work of Winnicott and Loewald. Winnicott's is a paper fundamentally about play. I suggest that for Winnicott, play always involves time, specifically the actual or feared loss of time or object, namely what I have referred to as the play of mourning. For Winnicott, temporality is inextricably bound with his notion of place. And they are both contained in the analytic setting. This is a setting that allows for the emergence of play and creative experiences of self, in time in general and for the time being. Like so many phenomena in Winnicott's theory building, time involves both actual or real time and time as incorporated psychically into the realm of illusion. Chapter 4 puts forward the ways that patient and analyst hold the paradox of time as actual and as incorporated into the realm of psychic illusion in order for the patient to be found.

The subterranean islands hypothesis for calcretes of the Yilgarn region in Western Australia applies to many stygobitic (subterranean-aquatic) species that are 'trapped' evolutionarily within isolated aquifers due to their aquatic lifestyles. In contrast, little is known about the distribution of terrestrial-subterranean invertebrates associated with the calcretes. We used subterranean Collembola from the Yilgarn calcretes to test the hypothesis that troglobitic species, those inhabiting the subterranean unsaturated (non-aquatic) zone of calcretes, are also restricted in their distribution and represent reciprocally monophyletic and endemic lineages. We used the barcoding fragment of the mtDNA cytochrome c oxidase subunit 1 (COI) gene from 183 individuals to reconstruct the phylogenetic history of the genus Pseudosinella Schaffer (Collembola, Lepidocyrtidae) from 10 calcretes in the Yilgarn. These calcretes represent less than 5% of the total possible calcretes in this region, yet we show that their diversity for subterranean Collembola comprises a minimum of 25 new species. Regionally, multiple levels of diversity exist in Pseudosinella, indicative of a complex evolutionary history for this genus in the Yilgarn. These species have probably been impacted by climatic oscillations, facilitating their dispersal across the landscape. The results represent a small proportion of the undiscovered diversity in Australia's arid zone. Key words: DNA barcoding, COI, species delimitation, Pseudosinella, subterranean island hypothesis. L'hypothese des ilots souterrains pour la formation des calcretes dans la region du Yilgarn en Australie Occidentale s'applique a plusieurs especes stygobitiques (aquatiques souterraines) qui sont 'captives' sur le plan evolutif au sein d'aquiferes isolees en raison de leur mode de vie aquatique. Cependant, peu de choses sont connues sur la distribution d'invertebres terrestres souterrains associes aux calcretes. Les auteurs utilisent les collemboles souterrains des calcretes du Yilgarn pour tester l'hypothese que les especes troglobitiques, celles qui habitent les zones souterraines non-saturees (non-aquatiques) des calcretes, sont egalement contraintes dans leur distribution et comprennent des lignages reciproquement monophyletiques et endemiques. Les auteurs ont employe le codage a barres avec un fragment du gene codant pour la sous-unite 1 de la cytochrome c oxydase (COI) mitochondriale chez 183 individus provenent de 10 calcretes de la region du Yilgarn pour reconstruire l'historique phylogenetique au sein du genre Pseudosinella Schaffer (Collembola, Lepidocyrtidae). Ces calcretes representent moins de5%de toutes les calcretes de la region, mais les auteurs montrent qu'au moins 25 especes inedites ont ete identifiees en etudiant la diversite des collemboles souterrains. Sur le plan regional, plusieurs niveaux de diversite existent au sein du genre Pseudosinella, ce qui indique un historique evolutif complexe pour ce genre au sein du Yilgarn. Ces especes ont vraisemblablement ete affectees par les oscillations climatiques, ce qui aurait facilite leur dissemination dans le paysage. Ces resultats representent une petite proportion de la diversite inconnue au sein de la zone aride de l'Australie.

The article presents the discussion on Angel Mounds State Historic Site in Evansville, Indiana, a significant prehistoric Mississippian village that is currently undergoing museum renovations. Topics include site's history and excavation, changes in artifact display practices due to the decolonization movement; and the notable artifacts found at the site, such as the kneeling human statue made of translucent fluorite.

Over the last 5 million years, numerous species of Australian stygobiotic (subterranean and aquatic) beetles have evolved underground following independent colonization of aquifers by surface ancestors, providing a set of repeated evolutionary transitions from surface to subterranean life. We used this system as an 'evolutionary experiment' to investigate whether relaxed selection has provided a source of variability for adaptive radiations into ecosystems containing open niches and whether this variability underpins phenotypic evolution in cave animals. Linear and landmark-based measurements were used to quantify the morphology of subterranean species from different aquifers, compared to interstitial and closely related aquatic surface species. Subterranean dytiscids were observed to be morphologically distinct, suggesting they have a different lifestyle compared to their surface relatives. However, variation in the measured traits was much greater in the subterranean species, and unstructured, showing no evidence of clustering that would indicate adaptation to specific niches. Furthermore, a previously identified pattern of repeated nonoverlapping size variation in beetles across aquifers was not correlated with repeated body shape evolution. The observed variability across body shape and limb traits provides support for the hypothesis that relaxed selection and neutral evolution underlie the phenotypic evolution in these species.

The author describes some of his interest in the painting of Richard Diebenkorn, the poetry of Bob Dylan, and a lifelong enjoyment of entomology and fly fishing as it comes into "play" with his analytic work. Diebenkorn's "Notes to Myself Upon Beginning a Painting," which were discovered after his death in 1995, are remarkably overlapping with elements of the ontological analysis of both Winnicott and Bion. The author elaborates a few elements of analytic listening from inside his personal "aesthetic matrix," a concept so helpfully introduced in Palmer's paper, "The Aesthetic Matrix: A Conversation Between a Painter and a Psychoanalyst." There is special attention to a few varieties of visual and verbal imagery linked to auxiliary containing functions for the analyst. [ABSTRACT FROM AUTHOR]
