We evaluated the effects of season (summer vs. autumn) and stream climate (temperate vs. Mediterranean) on litter decomposition using <em>Nerium oleander</em> leaves incubated in two Portuguese streams (temperate and Mediterranean regions). We quantified litter mass loss, litter chemistry, microbial biomass and activity, and invertebrate community structure. Decomposition was primarily structured by time, which explained most of the variation in mass loss, whereas season exerted a secondary but significant influence. In contrast, stream climate alone had no direct effect on decomposition rates. Seasonal differences in mass loss occurred only in the temperate stream, with higher decay rates in the summer-initiated experiment. Litter nitrogen content increased during decomposition, whereas phosphorus and proportional lignin content remained comparatively stable, consistent with slower loss of lignin relative to more labile litter constituents. Microbial indicators showed distinct temporal variation: fungal biomass was consistently higher in the temperate stream, whereas ATP increased later in the Mediterranean stream, and respiration peaked earlier processing in both streams. Invertebrate communities differed among streams but showed limited seasonal variation, with low shredder abundance in the Mediterranean stream. Overall, our results indicate that litter decomposition in our study streams is primarily governed by temporal dynamics and modulated by hydrological and biological factors, rather than climatic conditions alone.</div></div>","PeriodicalId":51110,"journal":{"name":"Limnologica","volume":"120 ","pages":"Article 126372"},"PeriodicalIF":1.8,"publicationDate":"2026-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148958380","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To our knowledge, this study provides the first report of zebra mussel colonization on narrow-clawed crayfish (<em>Pontastacus leptodactylus</em>) in Atikhisar Reservoir, Çanakkale, Türkiye. A total of 6634 crayfish were examined monthly from July 2020 to June 2021 to evaluate colonization prevalence, host-related correlates, attachment-frequency patterns across crayfish body regions, and associations with selected environmental variables. Zebra mussels were recorded on 321 crayfish, corresponding to an overall colonization prevalence of 4.84%. Colonization prevalence was higher in males (5.43%) than females (3.94%). Colonized crayfish had greater mean carapace length and body weight than non-colonized individuals, and colonized individuals were mainly concentrated in the 40.0–69.9 mm carapace length classes. A total of 2227 attached zebra mussels were recorded, most of which belonged to Class I (≤12.9 mm), indicating that colonization was mainly associated with small individuals. Attachment was recorded across seven crayfish body regions, with the dorsal carapace showing the highest attachment frequency, followed by the dorsal and ventral abdomen. Because body-region surface areas were not measured, these patterns were interpreted as attachment-frequency differences rather than evidence of active substrate preference or selectivity. Logistic regression indicated that crayfish carapace length, body weight, sex, water temperature, reservoir water level, and dissolved oxygen were associated with zebra mussel presence/absence, although model explanatory power was weak. These findings show that zebra mussel colonization on crayfish in Atikhisar Reservoir is associated with both host traits and environmental conditions, and they highlight the broader value of considering mobile benthic hosts when monitoring zebra mussel interactions in invaded freshwater systems. Future studies should incorporate zebra mussel density, larval availability, molting history, and body-region surface area to better evaluate the mechanisms underlying host-associated colonization.</div></div>","PeriodicalId":51110,"journal":{"name":"Limnologica","volume":"119 ","pages":"Article 126354"},"PeriodicalIF":1.8,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148542481","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the priming effects (PE) on nutrient release during decomposition, induced by input DOM of different sources in lakes, and their underlying microbial mechanisms, remain unclear. In this study, microcosm incubations were conducted to simulate the effects of DOM from different sources (algal, sewage, and soil) on nutrient release, microbial community structure, key taxa, and assembly processes during the decomposition of <em>Phragmites australis</em>. Results indicate that algal- and sewage-derived DOM enhanced decomposition, as evidenced by positive PE, with increases of 1.51–12.54% in the release of dissolved organic carbon, nitrogen, and phosphorus compared to theoretical values. Conversely, soil-derived DOM suppressed decomposition, showing negative PE with reduced release (6.87–16.82%). Partial least squares path model revealed that DOM significantly influenced microbial community structure by altering environmental factors. Key taxa such as <em>Nitrospira</em>, <em>Sphingopyxis</em>, and <em>Microvirga</em> exhibited significant correlations with nitrogen and phosphorus fluxes, indicating possible involvement in mediating the PE. Community assembly analysis revealed that algal-derived DOM mainly enriched microorganisms via stochastic dispersal limitation, sewage-derived DOM may induce positive PE through deterministic homogeneous selection, and soil-derived DOM exerted strong dispersal limitation, thereby filtering for specialist taxa. Overall, DOM-induced shifts in microbial communities are closely coupled with the PE observed during decomposition, implying their role as potential drivers.

In this study, we evaluated how environmental and spatial variables structure Gerromorpha beta diversity in streams of the Central Amazon. We sampled communities across four Amazonian sub-basins and collected environmental, spatial, and biological data. Beta diversity was quantified using local contributions to beta diversity (LCBD) based on abundance data (LCBD_ab), presence–absence data (LCBD_pa), and species contributions to beta diversity (SCBD). We then assessed the relationships between LCBD_ab and LCBD_pa and local environmental and spatial characteristics, as well as between SCBD and species attributes, including abundance, occupancy, niche breadth, and niche position. LCBD_ab was mainly explained by spatial structure, represented by multiple spatial axes, whereas LCBD_pa was primarily related to environmental variation, especially the Habitat Integrity Index (HII). Species with high abundance but low occupancy contributed more strongly to SCBD, as did generalist species with non-marginal niche positions. Overall, our results indicate that beta diversity in Gerromorpha metacommunities is jointly shaped by environmental filtering and dispersal limitation, with these processes influencing species abundances and occurrences in distinct ways. Maintaining environmental integrity and connectivity among sites is therefore crucial for preserving regional compositional variation and preventing biotic homogenization in Gerromorpha metacommunities.</div></div>","PeriodicalId":51110,"journal":{"name":"Limnologica","volume":"118 ","pages":"Article 126337"},"PeriodicalIF":2.0,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147858309","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
