Summary: This study used DNA metabarcoding to investigate dietary niche partitioning in an endemic radiation of mammals in the Philippines, revealing both niche partitioning and phylogenetically-uncorrelated adaptive evolution in this small mammal community. The data provide evidence for fine-scale resource partitioning within the community and shed light on the role of dietary adaptation in the co-occurrence of closely related species. The study reinforces the value of DNA metabarcoding as a tool for investigating ecological relationships and evolutionary ecology at both the community and phylogenetic level.

Summary: The research found a high level of dietary overlap between tortoises and skinks, but a negative correlation in herbivory preferences and minimal overlap in the most frequently consumed plants. The presence of tortoises is unlikely to have detrimental impacts on skinks, and could even benefit them in the long term by expanding palm-rich habitat. Tortoises may help control invasive plants, but further interventions may be needed to restore certain plant communities on the islet.

Summary: MacArthur and Wilson's theory of island biogeography has been important for predicting patterns of species diversity, abundance, and trait data. However, there is a need to incorporate the genetic component into these models and unify processes across different organizational scales. This review highlights the potential for developing a genetic theory of island biogeography and outlines two approaches for integrating genetic diversity patterns into community-scale models.

Summary: Invasive mammals are a major cause of native species extinction on islands. This study investigates the impact of resource competition between the invasive greater white-toothed shrew and the native pygmy shrew on Ireland. The results show that the invasive species can quickly alter its diet, leading to the decline of the native species and potential exhaustion of local resources, with severe implications for ecosystem functioning and services.

Summary: In this study, the fungal organisms present in soils at James Ross Island, north-east Antarctic Peninsula, were characterized using DNA metabarcoding. The detected taxa included widely-distributed phyla such as Ascomycota, Basidiomycota, and Mortierellomycota, as well as uncommon phyla such as Chytridiomycota, Rozellomycota, Monoblepharomycota, Zoopagomycota, and Basidiobolomycota. Unknown fungi and taxa identified at different taxonomic levels dominated the assemblages. The fungal sequence assemblages exhibited high diversity and richness, and moderate dominance, with the presence of saprophytic, pathogenic, and symbiotic fungi.

Summary: Environmental DNA (eDNA) sampling is a powerful and efficient approach for collecting information about species, and it may also provide information about population-level genetic variability. In this study, the researchers used eDNA sampling to estimate the genetic diversity and structure of an invasive fish species in the Great Lakes region. The study found that the genetic patterns observed from eDNA analysis were consistent with conventional tissue-based estimates. This research highlights the potential for eDNA sampling to reveal detailed population characteristics that can inform monitoring and management plans for difficult-to-sample species.

Summary: This study used DNA metabarcoding to identify macroinvertebrates and diatoms from different habitat samples, and obtained a different perspective of ecological conditions through a more comprehensive taxonomic assessment. The results showed that sites with 'good' condition had higher beta diversity, directed connectance, and modularity, indicating higher resilience compared to 'fair' condition sites. DNA metabarcoding data detected 29 site condition indicator species consistent with known bioindicators and expected relative tolerances, and identified 11 keystone taxa through trophic network analysis.

Summary: This study investigates the silicon isotopic composition of fresh and saline groundwater samples from Rottnest Island, Western Australia, revealing correlations between Si-30 values and water-aquifer interactions, groundwater residence time, and local hydrogeology. The increase in Si-30 values in fresh groundwater is attributed to removal of lighter Si isotopes into secondary minerals. The findings suggest that geologically young carbonate aquifers, like Rottnest Island, may be important sources of dissolved silicon in coastal regions with low riverine input and oceanic dSi concentrations.

Summary: Shallow-water hydrothermal vents are extreme environments characterized by high temperatures, low pH, and high CO2 concentrations. This study investigated the influence of these vents on prokaryotic community structure and functioning. The results showed that the microbial abundance and production were shaped by the water column's physical structure, and certain enzymatic activities were enhanced by hydrothermal fluids. Overall, this study provides insights into the coupling between microbial community structure and the biogeochemical cycling of nutrients in low-pH conditions.

Summary: This study investigates the reaction kinetics and products of ferrate (Fe(VI)) with primary amines, specifically amino acids. A new kinetic model involving ionizable intermediates is proposed to explain the unusual pH effect on the reactivity of Fe(VI) towards primary amines and amino acids. The study finds that the product distribution for amino acids differs significantly from that of uncarboxylated primary amines, with amino acids producing multiple products while primary amines mainly produce nitriles.

Summary: Many methods for estimating functional diversity of biological communities rely on measuring geometrical properties of n-dimensional hypervolumes in a trait space. However, current methods are limited in their ability to detect functional diversity patterns due to overlap of multiple hypervolumes. In this study, we propose a new approach based on occupancy rate to estimate functional diversity from a set of hypervolumes, and we introduce a permutation test to identify differences in occupancy rates between two sets of hypervolumes. We demonstrate the utility of our approach with two examples on aquatic macroinvertebrates.

Summary: Most metacommunity studies rely solely on morphological identification, which limits the characterization of metacommunities. In this study, morphology and DNA metabarcoding were combined to improve the characterization of an insect metacommunity. The results showed that the joint effect of environmental filtering and dispersal was more important than their individual effects in shaping metacommunity structure. Mixed-level and OTU-level identification were more effective than family and haplotype in characterizing the drivers of metacommunity structure.

Summary: Snake venoms contain bioactive proteins that can be used for drug discovery, and the evolution of snake venom proteins is driven by gene duplication and positive selection. Snake genomics is still in its early stages but has the potential to provide insights into venom evolution and toxinology. The presence of repeat sequences in snake genomes poses challenges for DNA sequencing, but advances in sequencing technologies and computational tools have improved our understanding of snake venom evolution.
