Myanmar is a biodiversity hotspot and holds at least 570 different freshwater fish species with a high amount of endemism. Nevertheless, freshwater systems in Myanmar are highly threatened by anthropogenic perturbation such as pollution.
We examined impacts on streams from nutrient enrichment and catchment degradation on the fish community composition and trophic structure. We studied 12 stream sites, and treated these as two groups (six impacted vs. six less impacted), as well as covering a gradient in degradation. We did quantitative electrofishing, collected potential food resources, invertebrates and fish for stable isotope analysis of δ13C and δ15N, and measured a number of environmental site variables. To determine fish diversity, we extracted DNA from tissue samples of 193 specimens, thereby identifying a total of 44 different species from 20 families.
The most impacted sites had higher nitrogen concentrations and lower minimum O2 saturation. Fish biomass m−2 increased with degradation as it correlated positively with total nitrogen concentration and negatively with minimum O2 saturation. Fish communities did not differ significantly between the two groups nor across the environmental gradient, except that pairwise similarities were negatively related to differences in catchment forest cover.
Likewise, trophic niches of the fish did not differ significantly between the two groups nor across the environmental gradient, but fish at the more impacted sites had significantly lower minimum δ15N signal and higher δ15N range compared to the least impacted.
The tropical fish assemblages studied were diverse and showed overall weak response to human impact. Likewise, there was little indication of differences in tolerance to environmental stress among taxa. Thus, in contrast to previous studies on macroinvertebrates in the same region, our results suggest that fish communities are less suitable as bio-indicators of environmental degradation and biodiversity loss in these tropical lowland streams.

With climate change and rising temperatures, the timing of spring is advancing in many parts of the world. Such environmental changes may have immediate effects on species communities, but also carry-over effects into later seasons. However, little is known about the extent of such carry-over effects for communities consisting of short-lived species with multiple life cycles in a year.
We used a 26-year dataset to explore the immediate and carry-over effects of spring temperature on freshwater zooplankton communities consisting of three taxonomic groups (Rotifera, Cladocera and Copepoda), sampled at three locations in a lake in central Norway. We first described the seasonal dynamics of zooplankton community abundance and species richness, as well as the ratio between abundance and species richness, using generalised additive mixed models (GAMM). Next, we used a sliding window analysis to identify the most important time during spring for which temperature affected community abundance and species richness, and the impact of this window on different parts of the seasonal curve of abundance and species richness of the community. This allowed us to explore whether spring temperature affected overall abundance and species richness, whether there were seasonal differences in the strength of the effect, how any effects varied between the three phyla, and whether they were consistent among the three localities.
Cladocera and Rotifera roughly followed the expected seasonal pattern, with a peak in total abundance. Copepoda, on the other hand, showed lower abundance in the middle of the sampling season. The shape of the curve also varied between localities. Spring air temperature affected the overall abundance, species richness, and abundance: species richness ratio throughout the season. In some cases, models with an interaction between spring temperature and Julian day were the best, indicating that the effect of spring temperature varied temporally in strength and direction.
Given the short life cycles of most zooplankton species present in our dataset, it is surprising that effects of spring temperature are visible throughout the summer and into early autumn. This implies that pulse disturbances may have long-lasting, multigenerational effects even in communities of short-lived species. Our study also illustrates how different zooplankton groups may vary in their response to temperature variations.

Channelised headwater streams are common in agricultural catchments in the Midwestern United States, Canada and Europe and serve as fish habitat despite being impacted by agriculture. The influence of climatic variables on fish communities in channelised agricultural headwater streams has not been documented.
Our research objectives were to identify the relationship between fish community structure and climatic variables in channelised agricultural headwater streams in northeast Indiana and central Ohio and to determine if fish community structure is better predicted by climatic variables or stream variables. We sampled fishes, compiled climatic data and measured water temperature and several stream hydrologic variables from 10 channelised agricultural headwater streams in northeast Indiana and central Ohio for 14 years.
Mixed effects modelling indicated that fish diversity and relative abundance of warmwater fishes, coolwater fishes, intermediate tolerant fishes, Cyprinidae, Percidae, invertivores and brood hiders were positively correlated (p < 0.05) with precipitation and fish abundance and the relative abundance of planktivores and guarder substrate choosers were negatively correlated (p < 0.05) with precipitation. Fish abundance and the relative abundance of invertivores, planktivores and brood hiders were positively correlated (p > 0.05) with air temperature. In general, stream variables were better predictors of fish community structure than climatic variables.
Our results provide insights into the relationships of fish communities with climatic and stream variables in channelised agricultural headwater streams that can be applied to help prioritise monitoring and management strategies for these small streams.

Submerged macrophytes in shallow freshwater ecosystems often encounter fluctuating nutrient and light conditions, which shape their growth strategies and interspecific interactions. However, the combined effects of these environmental factors on competition and trait plasticity remain underexplored.
We investigated interspecific competition and trait responses between Vallisneria natans and Myriophyllum aquaticum using a fully factorial replacement series experiment crossing two light regimes, three nutrient levels, and five planting ratios. The two light regimes were higher-light (206.3 ± 16.8 μmol m−2 s−1) and lower-light (78.4 ± 6.4 μmol m−2 s−1). The three nutrient levels were N1 (ambient; TN = 0.478 mg L−1, TP = 0.001 mg L−1), N2 (low enrichment; TN = 3.0 mg L−1, TP = 0.2 mg L−1), and N3 (high enrichment; TN = 8.0 mg L−1, TP = 0.8 mg L−1). Five planting ratios of V. natans to M. aquaticum were tested: 8:0, 6:2, 4:4, 2:6, and 0:8. We measured plant biomass, morphological traits (plant height, root length, and root-to-shoot ratio), and tissue nutrient concentrations (total nitrogen and total phosphorus). Competition indices including relative yield (RY), relative competition intensity (RCI), and relative crowding coefficient (RCC) were calculated to quantify interspecific interactions.
M. aquaticum exhibited greater biomass and tissue nutrient accumulation (total nitrogen and total phosphorus) under nutrient-rich, higher-light conditions, maintaining competitive dominance. In contrast, V. natans demonstrated higher morphological plasticity and competitive persistence under nutrient-poor and shaded conditions, increasing root-to-shoot ratio, plant height, and root length. These traits reflected a conservative growth strategy that enabled niche differentiation.
Competition indices revealed asymmetric interactions: M. aquaticum strongly suppressed V. natans under enriched conditions (low RY, high RCI), while V. natans showed higher RCC under stress, suggesting context-dependent shifts in competitive advantage.
Our findings highlight the significance of trait-based strategies in mediating macrophyte competition and offer insights into species selection for ecological restoration in variable freshwater environments. Moreover, the strong growth and resource acquisition abilities of M. aquaticum under nutrient-rich and well-lit conditions may also underpin its invasive success in eutrophic freshwater ecosystems.
