Summary: Pelagic microbes in lakes and oceans can be grouped into free-living, specialized oligotrophs and patch-associated generalists or copiotrophs. This review identifies genomic traits that enable pelagic freshwater microbes to thrive in their habitat, by comparing the genetic differences between pelagic marine and freshwater microbes and also freshwater sediment microbes. Metabolic differences, including transport functions, environmental information processing, and electron transport chain components, are found in pelagic freshwater microbes. This review also discusses lineages and mechanisms involved in habitat transitions and describes the distribution, ecology, and genomic make-up of abundant freshwater prokaryotes.

Summary: Genetic differentiation of rice landraces in Yunnan, China shows a clear geographical decline from south to north, with distinct divisions into japonica and indica groups, further differentiated into subgroups based on geographic locations. Patterns of gene flow suggest isolation by distance and environment, with significant associations between loci and environmental factors indicating adaptation to local environments. Geographical isolation and environmental heterogeneity play dominant roles in driving adaptive divergence among rice landraces in Yunnan, China due to limited dispersal.

Summary: Bacteria in lakes play important roles in biogeochemical cycles and ecosystem services. This study examined the distribution patterns of abundant and rare planktonic bacteria across 167 New Zealand lakes using 16S rRNA gene metabarcoding. The results showed that bacterial communities had a skewed distribution, with a few abundant species and many rare species. The abundance of local bacteria species was negatively correlated with the percentage of high productivity grassland in the catchment and positively correlated with altitude. Regionally rare bacteria species had a restricted distribution and were only found in a few lakes. Environmental processes played a larger role in structuring the regionally abundant community, while geographic distances were more important for regionally rare bacteria species.

Summary: Subspecies are traditionally defined by phenotypic differences, but morphological and genetic data may not always align. This study examined the genetic divergence of Banksia nivea subspecies in southwest Australia and found evidence for genetic differentiation among subspecies. The results supported the existing taxonomy but also revealed some inconsistencies, which may be attributed to differences in habitat and geography.

Summary: This study conducted a comparative analysis of four isolated edible dormouse populations based on morphometric skull characters. Significant differences were found between the Lankaran population and the three Greater Caucasus populations, correlating with the divergence time of these groups. The differences in skull features of the Lankaran population can be used to distinguish it from other populations. The morphological differences between Caucasian populations are less pronounced but still significant.

Summary: Through mitochondrial genomic and microsatellite datasets, we found that the 20 geographical populations of Neoneuromus ignobilis in East and Southeast Asia belong to five major lineages, originating from southern Vietnam, Yunnan + Laos + northwestern Vietnam, southwestern Guangxi, central China and eastern China. The continuous population expansion explains the widespread pattern of N. ignobilis and highlights the relatively weak impact of the Quaternary glaciations on the East Asian biota.

Summary: This study focused on constructing new categories of rurality in Colombia by considering armed conflict and isolation typology as variables, aiming to help policymakers and planners make better decisions. The results showed a strong correlation between variables, pointing out that municipalities highly affected by armed conflict are more isolated in terms of travel time to health care and higher education facilities. This isolation typology could assist the government in planning care pathways for patients with complex health needs and determining investment policies for improving access to higher education.

Summary: Habitat loss, overexploitation, invasive organisms, disease, pollution, and climate change have led to catastrophic declines in amphibian biodiversity, with montane amphibian species like Philoria kundagungan being particularly at risk. P. kundagungan has a highly restricted and fragmented distribution, limited to about 11 km(2) of potentially suitable habitat, and is strongly associated with high elevations (>800 m). Conducting call playback surveys across mountainous regions of Australia has provided valuable baseline data for future studies to monitor changes in geographic range and occupancy rate of P. kundagungan in response to increasing threats.

Summary: Microbes play a critical role in plant litter decomposition and the fate of carbon in rivers and riparian zones. The process of nutrient immobilization, whereby microbes acquire nitrogen and phosphorus from the environment during the decomposition of low-nutrient plant litter, is influenced by nutrient loading and changing climate. However, environmental controls on immobilization are poorly understood due to the complex interplay between environmental factors and plant litter chemistry.

Summary: By studying pond ecosystems in two different geographical regions of the world, it was found that temperate ponds are more influenced by environmental and spatial factors, while tropical ponds are more influenced by climatic variability and dispersal processes. The relative importance of space and environment varies greatly among different taxonomic groups, with active dispersers being more influenced by the environment and passive dispersers being more influenced by spatial factors. These results support the classic view of stronger abiotic niche constraints in temperate areas compared to the tropics.

Summary: This study presents two strains affiliated with the GKS98 cluster. Phylogenetic analysis suggests that these strains are closely related to the family Alcaligenaceae and previously described species Orrella amnicola and Orrella marina. Based on the phylogenomic trees and other characteristics, the authors propose the establishment of new genera Zwartia gen. nov. and Jezberella gen. nov., and the reclassification of Orrella amnicola into the new genus Sheuella gen. nov.

Summary: Recovery, recolonization, and adaptation are processes that regenerate local populations and communities after chemical stress. Recolonization involves the dispersal of organisms from other areas to fill empty niches, while adaptation refers to phenotypic and genetic changes that allow the persistence of existing taxa. Understanding the relative importance of these processes is crucial for the regeneration of biological communities after chemical exposure. This study provides case studies and recommendations to assess and compare the importance of these processes for risk assessment and ecosystem management.

Summary: This study compares the diversity of multiple taxa inhabiting tropical and Mediterranean temporary ponds using a spatial and temporal approach. The results show higher gamma and alpha diversity in tropical ponds, but phytoplankton and microinvertebrates from the Mediterranean region matched or exceeded tropical alpha diversity on some occasions. Spatial beta diversity did not differ between regions, and temporal beta diversity showed similar patterns. However, macroinvertebrates and amphibians exhibited differential effects on community variation observable only in animals with longer life-spans.
