Abstract Streams and rivers as ecological systems are distinct from all others have played a pivotal part in the development of human societies. They form network habitats connected by flow, coalescing into bigger downstream. dynamic hydrological cycle, draining landscapes with which they closely linked carrying precipitation organic inorganic materials architects landscape extremely ‘open’ systems. Running waters vary profoundly over range spatial temporal scales harbour diversity living things out proportion to their relatively limited extent. Most lotic species live on or stream bed, though some inhabit water column. Many occupy both aquatic terrestrial during lives. River organisms mostly (though not exclusively) small short-lived often obvious adaptations life flow.

Abstract Structure of natural communities is shaped by both abiotic characteristics and the ongoing processes community assembly. Important to this process are habitat selection behaviors subsequent survival colonists, in context temporal changes priority effects driven earlier colonists. Aquatic beetles prevalent temporary freshwater systems, form speciose assemblages, often early colonists ponds. While have potential influence structure through post‐colonization interactions (predation competition), our goal was determine whether presence beetle assemblages (versus patches without beetles) influences colonization oviposition a diverse group animals naturally colonized experimental landscape. We established mesocosms that either contained existing or no assessed abundances Treefrogs, Hyla chrysoscelis , mosquitoes, Culex restuans deposited fewer eggs containing while two beetles, Copelatus glyphicus Paracymus those at lower rates. One beetle, Helophorus linearis higher rates, Berosus infuscatus Tropisternus lateralis exhibited differences between treatments. Overall, there were assemblage richness patches. Our results illustrate importance species‐specific behavior determining species composition patches, emphasizing role influencing patterns Habitat response biotic can potentially create greater spatiotemporal niche separation among numerous, closely related (phylogenetically trophically), be simultaneously found similar across landscapes.

Abstract Larvae of water scavenger beetles (Coleoptera: Hydrophiloidea) are adapted to a wide variety aquatic habitats, but little is known about functional and evolutionary aspects these adaptations. We review the morphology evolution feeding strategies larvae families Hydrophilidae Epimetopidae based on detailed scanning electron microscope (SEM) analysis, analysis video records behaviour observations living larvae. There two main types mechanisms: chewing piercing-sucking. The character mapping using latest phylogenetic hypothesis for Hydrophiloidea infers system as ancestral condition. piercing-sucking mechanism evolved at least four times independently: once in (Epimetopus) three (Berosini: Berosus + Hemiosus; Laccobiini: Laccobius group; Hydrobiusini: Hybogralius). apparatus allows underwater extra-oral digestion decreases dependence an aerial environment. A study tracheal lineages reveals independent origins apneustic respiratory system, all them nested within with mouthparts. conclude that mouthparts represent key innovation, which subsequent adaptation influences diversification dynamics shift new adaptive zones.

Abstract Minute moss beetles (Hydraenidae) are one of the most speciose and widespread families aquatic Coleoptera, with an estimated 4000 extant species, found in majority habitats from coastal rock pools to mountain streams Arctic Circle Antarctic islands. Molecular phylogenetic works have improved our understanding evolutionary history megadiverse Hydraena , Limnebius Ochthebius recent years, but genera family not yet been included any analyses, particularly those which restricted Southern Hemisphere. Using a multimarker molecular matrix, sampling over 40% described species richness 75% currently recognized genera, we infer comprehensive phylogeny these predominantly Gondwanan Hydraenidae. Whilst focus on morphologically diverse, classified across all four hydraenid subfamilies, analyses suggest that may instead constitute single clade. As result findings, African genus Oomtelecopon Perkins syn.n. is shown nest within Coelometopon Janssens, New Zealand Homalaena Ordish Podaena synonymised Orchymontia Broun, South Pterosthetops Prosthetops Waterhouse, resulting Pterosthetopini being Prosthetopini Perkins.

We propose replacement name ordishi nom.n. for dilatata Ordish, 1984 (now junior homonym); altogether 39 new combinations proposed. Our Bayesian divergence times origin this ‘Gondwana group’ Africa plus Madagascar mid‐Cretaceous both vicariant dispersal processes, together extinctions, shaped biogeographic Hemisphere during Cretaceous, geographically conserved lineages. Finally, reconstruct ancestral habitat shifts phylogeny, revealing numerous changes occupancy including multiple origins fully terrestrial, humicolous taxa different regions.

Dramatic land-use changes in urban landscapes can drive water colour darkening by washing compounds, such as organic matter and iron, from terrestrial ecosystems into blue space, consequentially affecting aquatic communities.

Published: Dec. 24, 2024

ABSTRACT Urbanisation has led to decreasing quantity and quality of both terrestrial aquatic habitats, resulting in biodiversity loss urban ecosystems. Current research focused on spatial patterns along gradients, while temporal have received little attention. Here, we investigated how alpha beta diversity beetles changed through time, if pond structural connectivity (i.e., clustering the ponds) presence or absence fish affected change. We trapped diving (Dytiscidae) 20 ponds Helsinki Metropolitan Area, Finland, for six years analysed data using generalised linear mixed models index. found that (a) dytiscid diversity, i.e., species richness total abundances, decreased increased. (b) Clustered had higher than isolated ponds, but did not differ between clustered ponds; lower losses gains ponds. (c) Ponds with change during study period, without experienced declining over time; fish. Our results indicate assemblages biotic heterogenisation years, processes are different Dytiscids more likely maintain stable populations due immigration via rescue effects long‐lasting negative may replace urban‐sensitive urban‐adapted species. The dynamics invertebrates suggest improving landscape local habitat conditions can mitigate support communities
