Staining of subfossil chironomid head capsules: a method for improving the extraction process from lake sediments and peat
chironomids stain biological
2021/7/26
Subfossil chironomids are regarded as a useful biological proxy for palaeoenvironmental research, but picking chironomid head capsules from aquatic sediments is extremely time-consuming.
Harmful cyanobacterial blooms (CyanoHABs) are linked to increasing anthropogenic nitrogen (N) and phosphorus (P) inputs. However, CyanoHABs in many large lakes continue despite extensive abatement eff...

An experimental test of climate change effects in northern lakes: Increasing allochthonous organic matter and warming alters autumn primary production
ClimateChange lakes production GPP cDOM
2021/7/26
Climate changes are predicted to influence gross primary production (GPP) of lakes directly through warming and indirectly through increased loads of allochthonous coloured dissolved organic matter (c...
In temperate lakes, it is generally assumed that light rather than temperature constrains phytoplankton growth in winter. Rapid winter warming and increasing observations of winter blooms warrant more...

Phosphorus (P) release from sediment is a key process affecting the effectiveness of eutrophication mitigation.
High cadmium pollution from sediments in a eutrophic lake caused by dissolved organic matter complexation and reduction of manganese oxide
eutrophication lake pollution dissolved organic matter DOM DGT
2021/7/27
Eutrophication and metal pollution are global environmental problems. The risk of metal pollution is high in the eutrophic lakes because of high mobility of metal in sediments.

ater clarity (expressed as Secchi disk depth (SDD)) reflects light transmission capacity of a water body and influences growth of aquatic plants, aquatic organisms, and primary productivity.
密丛型苔草为适应地表过湿或积水环境的变化密集生长和根系迭生而产生地表起伏，形成草丘微地貌（又称“塔头”）。苔草草丘作为一种独特的湿地景观和珍贵的自然资源，广泛分布于北方泥炭地，具有生物多样性维持、碳固存、净化水质、提供生物栖息地等生态功能。近几十年来，由于人类大规模的开发利用，密丛型苔草沼泽面积急剧减少，功能退化。然而，目前关于密丛型苔草沼泽生态功能维持机制的认识仍较为有限，制约了对密丛型苔草沼泽...
