Riding the Storm: Microeukaryote Community Responses to Hurricane Disturbance

Journal of Eukaryotic Microbiology, Volume 73, Issue 5, September/October 2026.
ABSTRACT Sandy beaches are dynamic ecosystems where terrestrial and marine organisms coexist, resulting in diverse communities where microeukaryotes (protists, microalgae, and meiofauna) are key drivers. Understanding their diversity patterns and responses to stressors is essential for elucidating ecological processes, yet information on this subject ...

Synthesis and Antiparasitic Activities of New Organometallic Derivatives of the Benzimidazole Anthelmintic Drugs

ChemBioChem, Volume 27, Issue 15, 14 August 2026.
Organometallic derivatization of existing drugs is a common strategy to look for new drug candidates. This work describes the derivatization of the benzimidazole anthelmintic scaffold, from the synthesis of the organometallic derivatives to the evaluation of their biological properties. It highlights a broad range of antiparasitic activities and leaves

Histological and histochemical aspects of the penial glands of Girardia biapertura Sluys, 1997 (Platyhelminthes, Tricladida, Paludicola)

Brazilian Journal of Biology
Girardia biapertura was described with sperm ducts penetrating the penis bulb, subsequently opening separately at the tip of the penis papilla and receiving the abundant secretion of penial glands.

Karyotype Variation and Environmental Adaptation in the Invasive Alien Freshwater Flatworm Girardia in China

Ecology and Evolution, Volume 16, Issue 8, August 2026.
Our findings provide a comprehensive baseline of the distribution, reproductive strategies, and environmental adaptations of invasive Girardia species, and underscore the urgent need for continued monitoring and effective management to safeguard native biodiversity.

The dual role of detritus as resource and habitat: integrating non‐trophic processes to ecosystem dynamics

Oikos, Volume 2026, Issue 8, August 2026.
The diversity of ecological interactions, both trophic and non‐trophic, is central to understanding the assembly of communities. However, we have yet to study non‐trophic processes through their action on ecosystem compartments such as detritus involved in both recycling and habitat provisioning.

Titin Is Present in the Elastic Tethers That Connect Separating Anaphase Chromosomes in Crane‐Fly Spermatocytes

Cytoskeleton, Volume 83, Issue 7, Page 496-514, July 2026.
ABSTRACT Elastic tethers connect telomeres of separating chromosomes in anaphase of animal cells. Immunofluorescence staining of titin in crane‐fly spermatocytes, using 4 different antibodies, shows that the giant elastic protein titin seems to be a component of mitotic tethers: titin “strands” extend between separating chromosomes, connecting their ...

Variation in Meiofaunal Abundance and Composition Across an Estuarine Bay: Do They Comprise a Coherent and Distinct Entity Displaying Contrasting Patterns to the Macrofauna?

Ecology and Evolution, Volume 16, Issue 7, July 2026.
Is division of marine animals into macrofauna and meiofauna merely an arbitrary convenience, or, as has been claimed, does their size difference render them distinct and independent entities evolved under different ecological constraints? Those in the Knysna estuarine bay did not behave as distinct and discrete ecological entities, their individual ...

The polyclads (Platyhelminthes: Polycladida) from the Tropical Eastern Pacific: Commented checklist and description of a new species

European Journal of Taxonomy
In the Tropical Eastern Pacific (TEP), while knowledge of the order Polycladida is longstanding, at the moment no study has synthesized how many and which species are known from this region. In this work, a new species of polyclad from the Oaxaca coast,

Changing Pacific Salmon Nursery Lake Ecosystem Dynamics Over Centuries to Millennia: Insights From Sedimentary DNA Metabarcoding

Environmental DNA, Volume 8, Issue 4, July‐August 2026.
Sedimentary DNA metabarcoding tracks long‐term eukaryotic community change in Pacific salmon nursery lakes, revealing potential land‐use and climate influences on algal communities and resilience indicators. ABSTRACT Pacific salmon are keystone species in North Pacific freshwater, riparian, and marine ecosystems, but many populations have declined or ...
