Convergent genome streamlining accompanies independent miniaturization in the world’s smallest fishes

Miniaturization, the reduction of adult body size to an extreme degree, has evolved repeatedly across vertebrates. Yet its genomic underpinnings remain poorly understood. Cypriniformes, the most species-rich order of freshwater fishes, contains multiple miniaturized lineages that...

Integrative systematics of the Neotropical doryctine wasp genus Panama (Hymenoptera: Braconidae) and related genera with the description of a new genus

Context Panama Marsh (Hymenoptera: Braconidae) is a Neotropical doryctine wasp genus erected to contain a single species, P. canalia Marsh, primarily based on its distinctly extended pronotum forming a pronotal collar. Although several morphologically similar genera also possess...

Fimbriarioides intermedia and F. lintoni (Cestoda: Hymenolepididae): molecular phylogeny, species status, and transmission in Arctic coastal ecosystems.

has a trans-Arctic distribution and is represented by the same population in all these regions. This is due to the high vagility of its definitive hosts, sea ducks, which make long-distance migrations along the coasts of the northern Palaearctic seas, and the almost circumpolar d...

Post-Release Changes of the Goat’s Rue Rhizobia (Neorhizobium galegae bv. orientalis) Genomes in the Field: Prospects for Breeding the Symbiotically Effective Strains

Root nodule bacteria (rhizobia) fixing N2 in cooperation with legumes are broadly used for improving production of these plants inoculated with strains selected for high symbiotic activity. These bacteria are characterized by enormous evolutionary plasticity based on genomic rear...

Ciliated larvae turn spiny: novelties in the miniaturized miracidium of Bunocotyle progenetica (Digenea: Hemiuroidea)

Abstract Background Miracidia, the larvae of digeneans, infect a molluscan host. In many species they are ciliated swimmers that actively locate a snail. In several digenean lineages, however, the miracidia are miniaturized and enter molluscs passively, being swallowed. The contr...

Сharacteristics of aquatic invertebrates in the upper basin of Bakhta River (Krasnoyarsk Krai, Tungus Plateau) in the context of the distribution of relict and Baikal species

Pioneering studies were conducted on zooplankton, meiozoobenthos and macrozoobenthos assemblages in mountain-type taiga rivers: the Bakhta, Surindakan and Maigungda, as well as in the Yenisei River at the confluence with the Bakhta River. The studied watercourses are oligotrophic...

Arp2/3 complex-dependent actin remodeling is required for efficient RSV uncoating in A549 cells

ABSTRACT Productive human respiratory syncytial virus (RSV) cell entry requires coordinated interactions between viral proteins and host-cell factors at the plasma membrane-actin cortex interface. Branched actin networks remodel this interface, but their precise contribution to t...

Cortical Bipolarity Underlies Microtubule-Dependent Bidirectional Gliding in the Deep-Branching Apicomplexan Polyrhabdina pygospionis (Gregarinassina)

Manuscript in preparation — 30 August 2026 This is a work-in-progress manuscript prepared within Project No. 09I03-03-V04-00162, funded by the EU NextGenerationEU through the Recovery and Resilience Plan for Slovakia. This version is publicly deposited to document the current sta...

Enhancing knowledge of non-target tortricid fauna via pheromone monitoring of the quarantine fruit pest Grapholita molesta (Lepidoptera: Tortricidae) in Russia

The oriental fruit moth, Grapholita molesta (Busck, 1916), is an East Asian fruit pest that has spread to both hemispheres causing significant economic losses. In some countries, including Russia, it is considered a quarantine species which occurence and spread are monitored usin...
