Summary: This study assessed the genetic variation levels and patterns of freshwater crayfish populations in the Iberian Peninsula, revealing high genetic diversity significantly structured into three main genetic groups. The findings suggest the importance of considering these three phylogeographic groups as essential management units for the conservation of the species' remaining genetic diversity.

Summary: The stone crayfish Austropotamobius torrentium is globally endangered due to anthropogenic pressure, climate change, and the invasive signal crayfish Pacifastacus leniusculus. The study shows that climate change is likely to result in significant loss of suitable habitats for A. torrentium, putting highly diverse populations at risk of extinction. Furthermore, the threat from climate change appears to be greater for A. torrentium than the invasive crayfish species.

Summary: The study reported a stone crayfish population in a stream in southern lowlands of Romania, belonging to the most widespread phylogroup and sharing the same haplotype with specimens from Croatia. Unfortunately, this population likely disappeared due to crayfish plague, highlighting the vulnerability of isolated relic populations.

Summary: This paper investigates potential ethical conflicts in the conservation of the European native crayfish Austropotamobius pallipes, emphasizing the importance of considering the principle of fairness when evaluating the economic and recreational value of invasive species. Additionally, the discussion highlights the necessity of conservation for A. pallipes due to its existence value and role as an umbrella and keystone species, offering insights for similar conservation efforts involving native species threatened by invasive competitors.

Summary: This study assessed the performance of two strictly terrestrial eDNA sampling approaches to detect arboreal mammals and compared the performance of two detection methods within a single species. The results suggest that sampling eDNA from on and around trees could serve as a useful new monitoring tool for cryptic arboreal mammal communities globally.

Summary: This study aims to assess how habitat alteration and subsequent water quality changes affect the stone crayfish population in the Kustosak Stream (Croatia) through three selected sites under different levels of anthropogenic disturbance. The results showed that habitat alteration caused an overall reduction in population abundance and changes in size structure, however, it had not yet resulted in detectable genetic differences. Crayfish abundance was affected by the physicochemical parameters of water, including oxygen, calcium ions, nitrates, pH, and water temperature.

Summary: The effects of ozone water and ultrasound cleaning on the microbial community diversity of crayfish were studied through microbial viable count and 16S rRNA gene sequencing. The results showed that the combined treatment significantly reduced the viable count of various microorganisms.

Summary: The study shows that the presence of raccoons has negatively impacted the native crayfish populations, leading to a significant decrease or disappearance of crayfish in certain areas. Signs of raccoon presence were clearly observed, while crayfish populations remained abundant or even increased in areas where raccoons were absent. Urgent actions are needed to control raccoons and ensure the survival of the protected species.

Summary: This study investigates the impact of long-term contamination on the soil microbiome composition and diversity at an urban brownfield in Los Angeles. The findings suggest that the presence of heavy metals and organic pollutants shape the soil microbiome diversity, and certain bacteria and fungi show tolerance to these contaminants. The study recommends incorporating DNA-based multi-marker microbial community profiling in brownfield site assessment and restoration.

Summary: This study reveals sphere-specific microbial communities in European temperate forests, characterized by low connectivity. It emphasizes the stronger influence of microbial spheres rather than host identity. Only a few taxa inhabit both the top-canopy and soil spheres, yet they make up the majority of the abundance in each sphere.

Summary: This article reviews the application of eDNA metabarcoding in monitoring marine fish communities and discusses its prospects in biodiversity monitoring. eDNA metabarcoding can predict species richness, detect habitat segregation and biogeographic patterns, and monitor the dynamics of fish communities. It can also assess the impact of human activities on fish communities.

Summary: The study found that aquatic eDNA metabarcoding has the potential to inventory mammals in Neotropical environments, providing additional data for diurnal nonaquatic species and detecting species not found in line transect surveys, such as semi-aquatic, aquatic and nocturnal terrestrial and arboreal species. Although further developments are needed, eDNA can be used as a complement to traditional surveys.

Summary: This study investigated the effect of a slight temperature rise on the erythrocyte morphology of Antarctic fish. The results showed significant temporal differences in erythrocyte shape descriptors, but no significant differences between the two experimental conditions. The study highlights the challenges of comparative physiology in studying extremely sensitive organisms and suggests that the stabling effect in aquarium facilities can obscure the effects of experimental heat treatment.

Summary: Significant differences were found in the faecal samples of celiac patients and those on a gluten-free diet using SERS spectroscopy and 16S rRNA sequencing analysis. Although there were no significant differences in bacterial composition, the relative intensity of xanthine and hypoxanthine in the SERS spectra of patients on a gluten-free diet was significantly increased.

Summary: Diatoms are important phytoplankton in the oceans, contributing up to 40% of photosynthetic activity and playing a vital role in carbon and silicon cycles. Traditional microscopy methods for assessing diatom diversity are unreliable, but next-generation sequencing using rbcL marker can provide more accurate results. Through comparing microscopy, 18S-V9 metabarcoding, and rbcL metabarcoding, we identified new genera and species in the Gulf of Trieste and highlighted the limitations of microscopy and reference databases.

Summary: Mussels have a highly efficient innate immune system that allows them to tolerate infections well. Antimicrobial peptides (AMPs) in mussels exhibit gene presence/absence variation (PAV), resulting in a unique repertoire of defense molecules for each individual. The CRP-I gene cluster in the blue mussel was characterized, revealing the presence of numerous paralogous genes and pseudogenes. These CRP-I peptides are unlikely to function as antimicrobial agents or protease inhibitors, but they may play a role in defense against eukaryotic parasites.

Summary: The cave systems of the Neretva River basin in the Dinaric Karst are home to the endangered stygobiotic bivalve mollusk Congeria kusceri, which is facing rapid decline due to habitat degradation and lack of effective conservation regulations. The alteration of seasonal changes in water temperatures and alkalinity is likely involved in its disappearance, as it affects shell growth, spawning, and gametogenic cycles. RNA sequencing reveals tissue-specific gene expression and a shift in energy allocation towards reproductive organs during early autumn.

Summary: A species-specific assay based on hydrolysis probe chemistry was developed to detect Haplosporidium pinnae DNA in feces and pseudofeces of Pinna nobilis. The assay successfully detected H. pinnae in the feces of fan mussels in spring but not during summer. This noninvasive method can be used to monitor early-stage H. pinnae infections and routinely screen for the pathogen in live fan mussels and other environmental matrices.
