Summary: This study reveals the presence of exites at the base of most appendages in the Cambrian arthropod Leanchoilia, suggesting a deeper origin for exites in arthropod phylogeny. The discovery of a previously undetected exite at the base of appendages sheds new light on the evolutionary history of arthropods.

Summary: Radiodonts, including Stanleycaris hirpex, are iconic and bizarre-looking Cambrian animals that provide key insight into the development of the arthropod body plan. This study describes 268 exceptionally preserved specimens of Stanleycaris from the Cambrian Burgess Shale, providing the most complete reconstruction of a radiodont to date. The findings reveal new insights into the segmentation and neuroanatomy of radiodonts, as well as demonstrate a deep evolutionary continuity of certain features. The brain of Stanleycaris supports the hypothesis of an ancestrally bipartite head and brain for arthropods.

Summary: Groundwater dependent systems in the Great Basin of North America are crucial habitats for various species. The impacts of grazing on these habitats result in shifts in resources and changes in species composition. The abundance of arthropods in these ecosystems responded differently to grazing management and environmental variables, with an increase of approximately 50% in Coleoptera abundance in some meadows with higher grazing intensity.

Summary: A major limitation of current reports on insect declines is the lack of standardized, long-term, and taxonomically broad time series. This study demonstrates the utility of environmental DNA from archived leaf material to analyze temporal changes in plant-associated arthropod communities. The results suggest that insect decline may be driven by beta-diversity decay across space and time, resulting in gradual community turnover and biotic homogenization.

Summary: Arthropod antimicrobial peptides (AMPs) provide a potential source for new antibiotics with potent activity against multidrug-resistant bacterial pathogens. Synergistic effects can be achieved by combining AMPs from different sources. Hybrid peptides linked by glycine spacers show enhanced antibacterial activity, but can also exhibit increased cytotoxic activity.

Summary: Mosquito samples were collected near crocodile farms in the Darwin region of Australia to study virus population. Although no Kunjin virus was detected, the optimized MAVRIC system identified viruses from three different classes and demonstrated the persistence of an insect-specific flavivirus in mosquitoes. Additionally, a novel Hubei macula-like virus was detected in two mosquito genera, suggesting a possible horizontal transmission cycle between arthropods and plants.

Summary: Systematic literature reviews are commonly used in biodiversity conservation to identify knowledge gaps and strategies for improvement. However, these reviews are often not standardized and may have varying methods and data sources. A comparison of two systematic reviews on terrestrial arthropod conservation translocations revealed similar findings regarding geographic and taxonomic biases, but different conclusions about factors influencing success due to varying data sources. Improved communication and data sharing among researchers and practitioners is necessary to ensure comprehensive and accurate systematic reviews in conservation.

Summary: Vision is crucial for insects and other arthropods, with specializations like high spatial resolution, color discrimination, and detection of polarized light aiding in reproduction, foraging, and navigation. These adaptations allow them to excel in visual tasks despite their small size and physical limitations.

Summary: Increasing size, severity, and human proximity to fires in the western US drive a need for more effective ecosystem restoration post-fire. Few studies have investigated the impact of surface treatments, such as mastication of logging slash, on arthropod communities. This study found that predatory beetles were more abundant in mulch treatments in a large landscape-scale fire, while fungivores had no significant preference for mulch and several native bark beetles were more abundant in untreated sites. The size of the fire footprint and distance to the intact forest matrix likely impact arthropod community composition over time.

Summary: Global change poses challenges to the adaptive potential of forests, particularly impacting canopy-dwelling insect communities. Forest decline can have significant effects on canopy structure, microhabitats, trophic resources, and microclimates, with potential detrimental or beneficial impacts on different insect guilds depending on their ecological requirements. Further research and interdisciplinary collaboration are needed to better understand the mechanisms at play and address ongoing functional and conservation issues in temperate forest ecosystems.

Summary: This study investigates the biodiversity of adult arthropods in two grapevine plantations influenced by adjacent groves. The findings suggest the potential of introducing parasitoid/predatory insect species to control grapevine pests. The highest number of identified species was found in a grove near a black field. Introducing beneficial organisms, such as the predator Crysoperla carnea, is recommended to control grapevine moths in this ecosystem.

Summary: This article investigates the necessity of the crab's lobula plate for normal optomotor responses and finds that damaging this area can lead to a loss or impairment of response. The research findings are significant for understanding the evolutionary relationship between the lobula plates of insects and crustaceans.

Summary: This study investigates decision-making processes in prey-predator interactions, focusing on prey capture and escape behaviors in the crab Neohelice. The researchers found that males exhibit a higher probability of predatory response compared to females, and the probability of predatory response increases in males with starvation. Additionally, the study shows that unfed crabs intensify their predatory responses and exhibit different exploratory activities compared to regularly fed crabs.

Summary: This study found that Neohelice granulata crabs do not initiate attacks based on the size or speed of a dummy, but rely on actual size and distance. Monocular crabs showed a significant reduction in the number and accuracy of attacks, while binocular crabs were able to attack more frequently and precisely.
