Summary: The present study provides new insight into suitable microsporidian-host associations, relating host specialization in microsporidians infecting amphipods to degraded and recovering habitats across German river catchments. It offers a unique opportunity to understand the persistence of parasites following human disturbance and their establishment in restored rivers.

Summary: Understanding the osmoregulation nature of endemic aquatic organisms in desert springs is crucial for predicting their response to increasing environmental salinity. A study on two lineages of amphipods in the Chihuahuan Desert revealed that despite their divergence, both lineages showed similar physiological tolerances towards moderate salinity changes.

Summary: This study evaluated the sanitary status of two important oyster species in Portugal by examining their histopathology. Parasites were found in both oyster populations, along with tissue pathology. Higher prevalence of diseases was observed in wild populations. Biosecurity measures are crucial for controlling pathogen transmission.

Summary: This study in Xinjiang, China, used genetic analysis and species distribution models to understand the distribution patterns of freshwater amphipods and predict the impact of climate change on endemic species. The results showed high freshwater amphipod diversity in Xinjiang, with environmental factors responsible for niche differentiation among endemic species. Future climate change is expected to significantly affect the geographic distributions of endemic amphipods, highlighting the importance of prioritizing conservation efforts in areas with concentrated phylogenetic endemism.

Summary: Microsporidia, as obligate intracellular eukaryotic parasites, exhibit high diversity in lacustrine ecosystems, with approximately a quarter possibly representing undescribed genera or families. Variations in the abundance of Microsporidia were observed between the two lakes sampled and across the sampling period, potentially influenced by spatio-temporal variations of their potential hosts such as microeukaryotes and metazooplankton.

Summary: This study investigates the role of peptidoglycan recognition proteins (PGRPs) in detecting and immune responses to bacteria in insects, focusing on Manduca sexta. The findings suggest that PGRPs in the hemolymph of M. sexta mainly detect Gram-negative bacteria and certain Gram-positive bacteria with DAP-PGs on their surface. Additionally, some PGRPs are found to promote prophenoloxidase activation in the absence of a bacterial elicitor. These results challenge the common belief that the Toll pathway in insects is specific to Gram-positive bacteria.

Summary: The study investigated the prevalence of gastrointestinal parasites in cattle and buffaloes in Lower Dir Khyber Pakhtunkhwa, Pakistan, finding a higher prevalence in buffaloes than cows, with higher seasonal prevalence in summer. It was noted that most animals receiving previous anti-parasitic treatment had a low burden of parasitic infection.

Summary: The diagnosis of intestinal parasitic infections commonly relies on microscopic examination, but the ParaFlo(R) assays offer improved reliability and ease of use. When compared to routine methods, ParaFlo(R) showed similar performance in protozoa detection but slightly poorer performance in helminth detection.

Summary: A questionnaire survey in Europe found that leishmaniases are not universally notifiable in countries with autochthonous cases. Few countries have surveillance and control measures in place for both animal and human infections. Lack of resources is a major challenge for controlling leishmaniases, which are considered emergent diseases in most countries.

Summary: This study identified four SNPs associated with longevity in Cane corso dogs, located in genes TDRP, MC2R, FBXO25 and FBXL21. The longevity-associated SNP in FBXL21 was found to localize to the exon, with tryptophan replacing arginine in the protein of long-lived dogs.

Summary: This study reveals the significant role of mountainous areas in southern China in maintaining the diversity of endemic true bugs. However, China's protected areas are found to be insufficient in preserving this diversity. Protecting the diversity of endemic true bugs in the mountainous areas of southern China should be given more importance.

Summary: This study investigated the role of circulating hemocytes in both biomineralization and immunity in the hard clam Mercenaria mercenaria. The results showed that hemocytes in the extrapallial fluid (EPF) played a central role in shell formation by overexpressing genes and proteins related to biomineralization, ion transport, and regulation of carbonic acid levels. These hemocytes also showed higher calcium content compared to those in the hemolymph, suggesting their involvement as a source of calcium during biomineralization. Furthermore, the overexpressed genes and proteins contained dual-functional domains involved in both biomineralization and immune response.

Summary: Sewage released from lakeside development can introduce nutrients and micropollutants that can restructure aquatic ecosystems. Lake Baikal has been experiencing localized sewage pollution from lakeside settlements, with increasing filamentous algal abundance suggesting benthic communities are responding to localized pollution. The structured data can support continued monitoring and research efforts for Lake Baikal studies, while also helping characterize sewage prevalence and ecological consequences of anthropogenic disturbance across spatial scales for global studies of lakes.

Summary: Ancient Lake Baikal is a speciation hotspot and the gammaroid amphipods are the most diverse group in the lake. Recent research has shown that one common species, Eulimnogammarus verrucosus, actually consists of at least three cryptic species. By analyzing the phylogeny, genome sizes, and reproductive compatibility, this study confirms the genetic separation between these species and highlights the need for precise tracking of sample origin in future studies.

Summary: Sewage released from lakeside development can result in changes in ecological communities and impact the food web. The increase of filamentous algae near lakeside developments in Lake Baikal may be caused by localized sewage input, and even low levels of human disturbance can lead to spatial heterogeneity in ecological responses.

Summary: This study developed a pH-sensitive implant based on polyacrylamide hydrogel and successfully implanted it into the tissues of a small fish. The implant was able to monitor interstitial pH in fish muscles for at least two days. Despite some degradation and immune response, amorphous polyacrylamide is suitable for producing implantable sensors for small fishes.

Summary: In this article, a newly discovered cypovirus strain with potential for development of a modern biological insecticide is described. The strain shows high potency, relatively broad host range, true regulating effect, flexible production, interaction with enhancing adjuvants, and ecologically friendly features. Based on an alignment of CPV genomes, it is suggested that the enhanced host range of this new strain is a result of evolutionary events involving different CPV species within the same host. These findings indicate the need to consider CPVs as prospective agents for biocontrol products.

Summary: This study characterized the molecular epidemiology of rabies virus (RABV) in 13 European Russian regions using phylogenetic analysis. The results showed that all isolates belonged to either group C or group D, with high nucleotide identity observed among group C isolates. The study also discussed the potential contribution of local bat species to the distribution of rabies. Notably, the proportion of group D isolates has been decreasing over the years.
