Taxonomic and functional diversity of aquatic macroinvertebrate from natural forest as reference for streams health indicators in Lasolo Watershed, Southeast Sulawesi, Indonesia. Biodiversitas 24: 5523-5538. Macroinvertebrates are known to play a crucial role nutrient recycling serve valuable stream degradation indicators. Therefore, this study aimed examine the structural communities tropical Spatial sampling using multi-habitat method was conducted between September 2021 March 2022 five connected three drainage areas dryland farming. Data on cover, physical-chemical variables, samples were collected, while species richness trends across analyzed individual rarefaction curves. In addition, composition group also evaluated. The results showed that 2474 individuals belonging 77 genera recorded throughout area. We found reduction taxa by comparing impacted at genus, family, order levels with approximate values 83.1%, 74.07%, 55.6%, respectively. At least seven significantly different potential metrics differentiated ecosystem found, including number family (#family), insect (#insect), Ephemeroptera-Plecoptera-Trichoptera (#EPT), scraper (#scraper), well Shannon-Wiener diversity, Simpson Evenness, Margalef Richness index.

Lake ecosystems confront escalating challenges to their stability and resilience, most intuitively leading biodiversity loss, necessitating effective preservation strategies safeguard aquatic environments. However, the complexity of ecological processes governing lake under multi-stressor interactions remains an ongoing concern, primarily due insufficient long-term bioindicator data, particularly concerning macroinvertebrate biodiversity. Here we utilize a unique, continuous, in situ biomonitoring dataset spanning from 2011 2019 investigate spatio-temporal variation communities. We assess impact four crucial environmental parameters on Dongting Taihu, i.e., water quality, hydrology, climate change, land use. These two systems are representative lakes with Yangtze-connected disconnected subtropical floodplains China. find alarming trend declining taxonomic functional diversities among communities despite improvements quality. Primary contributing factors this decline include persistent anthropogenic pressures, alterations human use around lakes, including intensified nutrient loads reduced habitat heterogeneity. Notably, river-lake connectivity is pivotal shaping differential responses multiple stressors. Our results highlight strong correlation between within 2–5 km radius 0.05–2.5 shorelines Lakes respectively. findings importance implementing buffer zones specific spatial scales enhance diversity, securing essential ecosystem services enhancing resilience ecosystems.

Abstract Background Although phytoplankton are important primary producers in food webs, they relatively less studied large rivers compared to other types of systems. To fill this research gap, we taxonomic and functional composition their relationships with water quality, habitat, climate, land use across 30 river sections the middle lower reaches Yangtze River during 2017–2018. Results Major observed groups were cyanobacteria, bacillariophyta, chlorophyta. Phytoplankton total abundance, biomass, species richness significantly decreased dry season wet season, differing between seasons. differences seasons mainly contributed by Oscillatoria sp., Pseudanabaena Melosira granulata . The dfferences P (including Closterium sp.), Lo Merismopedia Peridinium Ceratium Gymnodinium J Pediastrum Tetraedron Crucigenia Scenedesmus Coelastrum sp.). variance partitioning showed that quality (NO 3 -N, suspended solids, turbidity) habitat (water flow, bank channel conditions) critical factors shaping patterns, followed climate use. Conclusions indicated there was significant seasonal variation River, primarily driving patterns. Our study contributes understanding natural anthropogenic drive successional processes River. These findings have implications for environmental management as well towards ecological restoration rivers.

Human mobility and goods transportation are essential processes that lead to pest propagation, accurately characterizing spatial transmissibility has always been a popular research topic. Therefore, we propose modeling quantification method based on nighttime light remote sensing reflect human integrate this with other variables map the spreading risk. First, residential areas in China extracted from annual NPP/VIIRS datasets. Then, index is established GIS cost-distance analysis impedance parameters related geographical land use features. Consequently, propagation risk of human-induced Hyphantria cuneas assessed binary logistic model. The results show obtained images can be used assess accessibility continuous way field. When cunea prediction was adopted, accuracy range improved by nearly 5% for occurrence 3.3% overall, significant difference observed Wilcoxon signed-rank test compared effect anthropogenic factors quantified considering basic geographic information infrastructure In addition, all model R2 values increased at different levels. effectively characterize pattern impacts displays high prediction. Understanding mechanism pests important provides reference achieving early warnings regarding spreading, performing potential host analyses infection caused unknown pathogens, ecological interference.

The biotic integrity of streams is frequently compromised by anthropogenic disturbance; thus, it important to study the potential mitigating effects undisturbed riparian zones on within disturbed watersheds. In this study, two first-order northern Michigan located 1 km apart in adjacent agricultural watersheds, but with differing land use, were compared observe intact forest immediate 100 m stream corridor. Both had high specific conductance values associated streams. a primarily forested corridor, however, greater canopy cover, faster velocity, coarse substrate, lower percentage organic sediment, water temperatures, higher dissolved oxygen, taxonomic richness, relative biomass shredders, gathering collectors, and more pollution intolerant taxa than Moreover, benthic macroinvertebrate assemblages highly distinct from each other, dominated aquatic insects like mayflies caddisflies, non-emergent isopods amphipods.

Abstract Urbanization-induced environmental changes are becoming a major threat to river systems. However, little is known about how urbanization affects aquatic microbial communities despite their critical role in maintaining ecological processes and nutrient cycling. Here, we investigated assembly of habitat generalists specialists different stages subtropical rivers. The results highlight that nitrogen compounds can influence the composition community. Proteobacteria Bacteroidetes, as well Cyanobacteria were identified dominant phyla Both total diversity species richness significantly higher than specialists, while beta was low-level rivers (LUS) high-level (HUS). For generalist, heterogeneous selection most important process for HUS winter, but dispersal limitation, drift other nondominated mainly establishment LUS whether summer or winter. Similarly, stochastic main HUS, In winter LUS, more complex network found stronger complexity robustness co-occurrence compared HUS. Overall, these suggest play key shaping urbanization-induced homogenization communities. insights gained from this study may be helpful understanding mechanisms.
