Summary: Terrestrial isopods have developed various behavioral and morphological adaptations to avoid terrestrial predators, including tonic immobility, conglobation, and clinging to the ground. However, most of these strategies have not been studied.

Summary: This data paper presents a recent and comprehensive inventory of terrestrial isopods in Belgium between 2011 and 2020. The inventory covered every 10 x 10 km(2) cell of the UTM grid in Belgium, resulting in 19,406 dataset records of 35 terrestrial isopod species. The data was collected through various methods and includes hand-collection, pitfall trap data, and citizen science observations.

Summary: Insecta is the most diverse group in the animal kingdom, and COI gene is commonly used for species delimitation. However, high intra-specific genetic variation in insects can lead to false positives in COI-based species delimitation. The threshOpt and localMinima algorithms in the Spider package are recommended for threshold-based species delimitation studies in insects. More comprehensive research is needed on the genetic variation in COI among Insecta, and the abundant COI data in BOLD provides an opportunity for such assessment.

Summary: The study found that terrestrial isopod activity in forests is more stable compared to open landscape habitats, indicating that climate stability in forests leads to more stable levels of terrestrial isopod activity. Activity patterns in anthropogenic habitats are more tempered compared to open landscape habitats, but highly variable, suggesting that more research is needed to unravel the underlying mechanisms.

Summary: This study genetically compared specimens of Acetes americanus collected in South America with Acetes americanus carolinae sampled in North America. The results showed clear genetic differences between them, supporting the idea that A. a. americanus and A. a. carolinae are distinct subspecies. Additionally, a new subspecies, A. a. Brazil 2, was discovered on the Brazilian coast. Further research is needed to confirm and describe this new subspecies.

Summary: The study found that TiO2 nanoparticles inhibited the growth of maize plants in alkaline soil by affecting plant length and root size, while the impact on plants in acid soil was minimal. Additionally, a higher accumulation of titanium was found in maize tissues grown in alkaline soil compared to those in acid soil. Increasing TiO2 nanoparticles in soil organic matter led to higher Ti concentrations, which in turn harmed the survival and weight of terrestrial isopods.

Summary: This study investigated the population genetics of Propylea japonica in China using nuclear microsatellite sites and mitochondrial COI genes. The results showed moderate genetic diversity in the microsatellite dataset and high genetic diversity in the mitochondrial genes. Populations from the Yellow River basin had higher genetic diversity than those from the Yangtze River basin. While there was no significant genealogical structure, there was some population structure signal, possibly due to gene flow between populations.

Summary: This study focuses on the local hydrological cycle in Manaus, at the center of the Amazon Basin, and observed how groundwater plays a major role in influencing the local gravity signal. It was found that there is a strong correlation between groundwater and gravity variations, while the influence of river height on the gravity signal is minimal.

Summary: Our study involved collecting terrestrial isopods and termites in the Brazilian Atlantic forest, sequencing and identifying Wolbachia strains in these groups, and constructing phylogenies that showed significant jumps of Wolbachia between terrestrial isopods and termites despite their phylogenetic distance, suggesting likely horizontal transmission of supergroup F Wolbachia between the two species. Our findings contribute to understanding the success and distribution of this symbiont.

Summary: This study tested the performance of COI as a DNA barcode in Orthoptera and evaluated its effectiveness using various analysis methods. The results showed that COI can serve as a reliable DNA barcode in Orthoptera, although its efficiency may vary depending on the need for additional information. COI demonstrated good performance in terms of intra- and inter-specific distances, barcode gap, and Probability of Correct Identification (PCI).

Summary: In this study, the relationship between genome size evolution and transposable elements in Drosophila was investigated. The results showed that genome size and the fraction of repetitive elements were determined by the evolutionary history of the species, but the content of transposable elements exhibited some discrepancies. Recent transposition events were detected in different superfamilies, and the low genomic GC content suggested a facilitation of transposable element mobilization through relaxed natural selection. The superfamily DNA/TcMar-Tigger was also found to potentially contribute to genome expansion. The process of speciation may promote an increase in the fraction of repetitive elements and genome size.

Summary: A new genus of Pudeoniscidae, Loretoniscus gen. nov., and a new species, Loretoniscus mashiriaensis gen. et sp. nov., from Peru are described. The new genus is characterized by the absence of dorsolateral furrows on pereonite 1 epimera, ventral lobes on pereonites 1 and 2, a telson with a distal portion covering uropod endopods, and pleopod 1-2 exopods with respiratory areas. This discovery considerably expands the distribution of the Pudeoniscidae family in the Neotropical region.

Summary: Euryades corethrus is an endemic Troidini butterfly species found in grasslands of southern Brazil, Uruguay, Argentina, and Paraguay. Due to habitat loss caused by conversion to crops and pastures, it is now endangered in these areas. Genetic analysis using the COI marker revealed low genetic variability and gene flow between populations, indicating a lack of population structure. The loss of habitat poses a significant threat to E. corethrus, potentially leading to isolation, loss of genetic diversity, and ultimately extinction if conservation measures are not implemented.

Summary: Transposable elements are an important part of the genome that can influence organisms through various mechanisms. In this study, we compared and evaluated the presence, structure, and copy number of three hAT superfamily transposons in different strains of Drosophila willistoni species. We found that these transposons were widely distributed in the species, but with some variations among strains. These differences could reflect the genomic and chromosomal plasticity of D. willistoni in adapting to different environments.
