is a common intracellular bacterial genus that infects numerous arthropods and filarial nematodes. In arthropods, it typically acts as a reproductive parasite, leading to various phenotypic effects such as cytoplasmic incompatibility, parthenogenesis, feminization, or male-killing. Quill mites (Acariformes: Syringophilidae) are a group of bird parasites that have recently attracted increasing interest due to the detection of unique phylogenetic lineages of endosymbiotic bacteria and potentially pathogenic taxa.

Fundamental constraints and questions from the study of martian meteorites and the need for returned samples.

Proc Natl Acad Sci U S A

January 2025

School of Geographical and Earth Sciences, Gregory Building, University of Glasgow, Glasgow G12 8QQ, Scotland.

Physical materials from planetary bodies are crucial for understanding fundamental processes that constrain the evolution of the solar system, as samples can be analyzed at high precision and accuracy in Earth-based laboratories. Mars is the only planet outside of Earth from which we possess samples in the form of meteorites. Martian meteorites (n > 350) have enabled constraints to be placed on various aspects of the red planet's formation and evolution, notably: that Mars accreted and differentiated rapidly; that the planet has a complex volatile element evolution; and that it has always been volcanically active with a rich and diverse magmatic history.

Extensive genome-wide phylogenetic discordance is due to incomplete lineage sorting in the rapidly radiated East Asian genus Nekemias (Vitaceae).

Hunan Provincial key Laboratory of Ecological Conservation and Sustainable Utilization of Wulingshan Resources, College of Biology and Environmental Sciences, Jishou University, Jishou, Hunan, 416000, China.

Background And Aims: Nekemias is a small genus of the grape family, with nine species discontinuously distributed in temperate to subtropical zones of the Northern Hemisphere but mostly in East Asia. Previous phylogenetic studies on Nekemias have mainly based on a few chloroplast markers, and the phylogenetic framework and systematic relationships are still highly contested.

Methods: We carried out a systematic framework reconstruction of Nekemias and intra-generic reticulate evolutionary analyses based on extensive single-copy nuclear and chloroplast genomic data obtained by the Hyb-Seq approach, combining genome skimming and target enrichment.

Article Synopsis
  • A new genus and species, Burmophilopota wintertoni, has been discovered in mid-Cretaceous Burmese amber, marking it as the oldest known member of the Philopotinae subfamily.
  • The morphological features suggest that this species is an early ancestor of the Philopotinae group.
  • The well-preserved details in the amber indicate that it may have played a role in pollinating flowering plants during the Mesozoic era, providing insights into the evolution of pollinating flies.

Between 2022 and 2023, over a thousand larvae and pupae of sugarcane borers in the genus Diatraea Guilding, 1828, were collected in the state of Nayarit, Mexico, and reared to adults to identify them based on the morphology of genitalia. Although two species, Diatraea considerata Heinrich, 1931, and D. magnifactella Dyar, 1911, had been reported to occur in western Mexico, we discovered a new species of sugarcane borer, Diatraea nayaritella Robles & Solis, sp.

Populations of forest trees exhibit large temporal fluctuations, but little is known about the synchrony of these fluctuations across space, including their sign, magnitude, causes and characteristic scales. These have important implications for metapopulation persistence and theoretical community ecology. Using data from permanent forest plots spanning local, regional and global spatial scales, we measured spatial synchrony in tree population growth rates over sub-decadal and decadal timescales and explored the relationship of synchrony to geographical distance.

Department of Anthropology, National Museum of Natural History, Smithsonian Institution, Washington, DC 20013-7012, USA.

People have influenced Earth's biodiversity for millennia, including numerous introductions of domestic and wild species to islands. Here, we explore the origins and ecology of the Santa Catalina Island ground squirrel (SCIGS; ), one of only five endemic terrestrial mammals found on California's Santa Catalina Island. We synthesized all records of archaeological/palaeontological SCIGS, conducted radiocarbon dating and stable isotope analysis of the potentially earliest SCIGS remains and performed genetic analysis of modern SCIGS.

Institute of Marine Science and Technology, Shandong University, 72 Binhai Road, Qingdao, 266237, China.

Mollusca, the second-most diverse animal phylum, is estimated to have over 100,000 living species with great genetic and phenotypic diversity, a rich fossil record, and a considerable evolutionary significance. Early work on molluscan systematics was grounded in morphological and anatomical studies. With the transition from oligo gene Sanger sequencing to cutting-edge genomic sequencing technologies, molecular data has been increasingly utilised, providing abundant information for reconstructing the molluscan phylogenetic tree.

We present a molecular phylogeny for the subtribe Ecliptinae (Asteraceae, Heliantheae) based on three plastid (, , and ) and two nuclear (nrITS and nrETS) markers. The results of the phylogenetic reconstruction were utilised as a topological constraint for a subsequent divergence dating analysis and ancestral range reconstructions. We sampled 41 species and 40 genera (72%) of Ecliptinae and two species of (as outgroups) to elucidate the generic relationships between the genera of this subtribe.

The Radar for Europa Assessment and Sounding: Ocean to Near-surface (REASON) is a dual-frequency ice-penetrating radar (9 and 60 MHz) onboard the Europa Clipper mission. REASON is designed to probe Europa from exosphere to subsurface ocean, contributing the third dimension to observations of this enigmatic world. The hypotheses REASON will test are that (1) the ice shell of Europa hosts liquid water, (2) the ice shell overlies an ocean and is subject to tidal flexing, and (3) the exosphere, near-surface, ice shell, and ocean participate in material exchange essential to the habitability of this moon.

Background: Coevolution between modern aphids and their primary obligate, bacterial endosymbiont, Buchnera aphidicola, has been previously reported at different classification levels based on molecular phylogenetic analyses. However, the Buchnera genome remains poorly understood within the Rhus gall aphids.

Results: We assembled the complete genome of the endosymbiont Buchnera in 16 aphid samples, representing 13 species in all six genera of Rhus gall aphids by shotgun genome skimming method.

Article Synopsis
  • The spotted wing drosophila (Drosophila suzukii) has rapidly spread globally and poses a threat to various fruits due to its unique reproductive methods.
  • Research focuses on the Ganaspis near brasiliensis parasitoids, particularly a lineage called G1, which is more host-specific to D. suzukii compared to others, highlighting the importance of differentiating cryptic species for pest management.
  • Study findings reveal significant genomic and reproductive differences between G1 and another lineage (G3), supporting the decision to introduce only the more effective G1 lineage for controlling the pest in North America and Europe.

The language of light: a review of bioluminescence in deep-sea decapod shrimps.

Biol Rev Camb Philos Soc

October 2024

Department of Biological Sciences, Florida International University, Institute of Environment, 3000 NE 151st St, North Miami, FL, 33181, USA.

In the dark, expansive habitat of the deep sea, the production of light through bioluminescence is commonly used among a wide range of taxa. In decapod crustaceans, bioluminescence is only known in shrimps (Dendrobranchiata and Caridea) and may occur in different modes, including luminous secretions that are used to deter predators and/or from specialised light organs called photophores that function by providing camouflage against downwelling light. Photophores exhibit an extensive amount of morphological variation across decapod families: they may be internal (of hepatic origin) or embedded in surface tissues (dermal), and may possess an external lens, suggesting independent origins and multiple functions.
