Summary: In the ephemeral inland lakes of the Monegros Desert, a study found a higher diversity of bacterial and fungal microbiomes in high salinity environments, with no dominance of a few salt-in organisms. The dynamic nature of these lakes may have provided a competitive advantage for more versatile organisms, compared to those adapted to stable high salinities typically found in solar salterns.

Summary: This study found that the microbial biofilm communities near mariculture areas can affect the settlement of coral larvae. The biofilm farthest from the mariculture area had a higher effectiveness in inducing the settlement of Acropora tenuis larvae. These biofilms were characterized by a greater proportion of crustose coralline algae and gammaproteobacterial taxa, while biofilms closer to the mariculture zone had a higher proportion of cyanobacteria and no crustose coralline algae. These findings suggest that nutrient enrichment from mariculture activities can alter the composition of biofilm-associated microbiome and indirectly affect coral larval settlement.

Summary: Advances in high-throughput sequencing technology are changing marine monitoring by enabling rapid and accurate detection of species in complex samples. An international experiment showed that while there was variation in results from different laboratories, the primary signal in the data was consistent, with samples grouping by geographical origin. Post hoc data clean-up, such as removing low-quality samples, improved sample classification accuracy significantly.

Summary: The availability of soil phosphorus can affect plant growth, root-soil interactions, and rhizosphere microbial community composition. This study investigated the rhizosphere microbial communities of 24 species of eucalypts under low or sufficient soil phosphorus availability. It was found that eucalypt species identity was the main factor determining the composition of the rhizosphere microbial community, while the effect of phosphorus availability varied among species.

Summary: This study provides high-resolution digital pictures and molecular data of male and female I. rugicollis for the first time, and morphological comparison with I. cornutus could not resolve uncertainties in the latter species' validity. Further molecular comparisons with new specimens of I. cornutus are needed to confirm its status. This study represents the first comprehensive molecular phylogenetic analysis of western Palearctic Pholeoixodes species, including I. rugicollis, and confirms the phylogenetic position of the subgenus Eschatocephalus within Pholeoixodes.

Summary: The present study characterized ticks infesting dromedary camels and cattle in Hofuf, Eastern Saudi Arabia, and detected Theileria annulata DNA for the first time in the region. Hyalomma anatolicum and Hyalomma dromedarii were identified as potential vectors for T. annulata in cattle for the first time in Saudi Arabia.

Summary: This study identified Sarcocystis species in Barbary sheep found in Southern Spain, with thick-walled sarcocysts corresponding to S. tenella/S. capracanis. Only thick-walled species were identified molecularly, with further research needed for accurate taxonomic identification due to the lack of cross-transmissibility between sheep and goats despite morphological similarities.

Summary: This study examines the relationship between microbial community dynamics and DMS concentrations in an oceanographic time series conducted on the east Australian coast. The results show that seasonal shifts in microbial community composition affect the net DMSP concentrations, with certain phytoplankton species producing more DMSP than others. Additionally, planktonic bacteria play a significant role in producing DMSP and DMSO in ocean surface waters.

Summary: Ciliates play important roles in ecological, environmental, evolutionary, and ontogenetic research. This study identifies the phylogenetic position of Chaetospira sinica sp. nov. and provides morphological and morphogenetic data to support its validity. Additionally, the morphologic and molecular data of exconjugant cells are provided.

Summary: A major unresolved issue in biology is why phenotypic and genetic variation is sometimes continuous, yet other times packaged into discrete units of diversity, such as morphs, ecotypes, and species. In theory, ecological discontinuities can impose strong disruptive selection that promotes the evolution of discrete forms, but direct tests of this hypothesis are lacking. Here, we show that Timema stick insects exhibit genetically deter-mined color morphs that range from weakly to strongly discontinuous.

Summary: This study used classical microscopy and eDNA metabarcoding to analyze the composition of phytoplankton in lakes. The results showed that eDNA metabarcoding method is sensitive to species change, but there are differences in the taxonomic and functional group composition, as well as the comparison of relative biomass and sequence number.

Summary: Little is known about marine arthrotardigrades due to difficulties in sampling, resulting in limited molecular data. This study provides the first investigation into COI haplotype diversity in a marine tanarctid and reassesses arthrotardigrade phylogeny. COI, 18S and 28S rDNA sequences were obtained from Actinarctus doryphorus and new 18S sequences from two marine echiniscoidids. Phylogenetic analysis confirms Tanarctidae as a separate clade from Halechiniscidae and suggests that the order Arthrotardigrada should be suppressed.
