The skipjack herring Alosa chrysochloris inhabits Gulf of Mexico drainages, primarily the Mississippi River Basin, and estuarine environments in the Gulf of Mexico. The trophic ecology of the skipjack herring is poorly understood, therefore we quantified the length, mouth gape and gut contents of juvenile skipjack herring from the Mississippi River (fish n = 6), Illinois River (fish n = 181) and Ohio River (fish n = 255) and t...

Understanding how demographic dynamics interact with environmental heterogeneity is central to explaining patterns of genomic variation in the marine realm. Indo‐Pacific bottlenose dolphins ( Tursiops aduncus ) occur along most of the Australian coastline, from tropical to temperate waters, encompassing pronounced differences in temperature, salinity, chlorophyll‐a concentration and ocean currents. Using whole‐genome sequencin...

Frontotemporal dementia (FTD) is a neurodegenerative disease characterized by significant clinical and genetic heterogeneity, with approximately 40% of cases linked to hereditary genetic mutations, including MAPT , GRN , and C9ORF72 . Recently, microRNAs (miRNAs) have emerged as key regulators of cellular processes related to neurodegeneration and as potential biomarkers for FTD. However, their relevance in presymptomatic stag...

Aim Biogeographical frameworks inform effective marine spatial planning, assessing ecological patterns across taxa and environments. In the Galapagos Archipelago, benthic bioregions guided marine reserve zoning, yet their representation of the mid‐water environment remains unassessed. Our study aimed to strengthen the understanding of patterns in marine biogeography in Galapagos by assessing whether the currently accepted bent...

With the increase of organic agriculture throughout Europe, there is also an increase of stockless organic farms. On mixed farms, growth of perennial legume-grass mixtures as well as farmyard manure are important contributors to soil fertility and play a key role for nutrient management. On stockless farms, such crops have no direct economic use and their cultivation is therefore questionable, which poses challenges for mainta...

Salinity gradients and fluctuations can create a natural ecological filter, with few species tolerating salinity above 50 practical salinity units (PSUs). We investigated how an inverse salinity gradient affected marine community diversity and composition in Shark Bay, a remote hypersaline coastal embayment in Western Australia. We used 16S(fish), 18S and 16S(Bacteria) eDNA metabarcoding assays to analyse genetic sequences col...

Metacommunity theory has expanded our understanding of how spatial dynamics and local interactions influence species communities. Different assembly archetypes, reflecting different roles of species differences, habitat differences, and dispersal have been described, but we lack empirical studies specifically in terrestrial habitats testing which archetype is most important. In a replicated design, we experimentally enhanced s...
