Limnology and Oceanography, Volume 67, Issue 12, Page 2649-2664, December 2022., 2022 Abstract Sewage released from lakeside development can reshape ecological communities. Nearshore periphyton can rapidly assimilate sewage‐associated nutrients, leading to increases of filamentous algal abundance, thus altering both food abundance and quality for grazers.

Limnology and Oceanography, Volume 67, Issue 12, Page 2718-2733, December 2022., 2022 Abstract Continental freshwater systems are particularly vulnerable to environmental variation. Climate change‐induced desertification and the anthropogenic exploitation of hydric resources result in the progressive evaporation and salinization of inland water bodies in many areas of the globe.

Corn cob pyrolysis: A systematic literature review of methods and applications
The Canadian Journal of Chemical Engineering, EarlyView.Mapping the research landscape of corn cob pyrolysis. Abstractas The agricultural sector is experiencing a surge in waste generation due to population growth, creating an urgent need to convert byproducts into value‐added products. Maize (Zea mays L.), a leading global crop, produces significant byproducts, such as corn cob, which are often undervalued.

Limnology and Oceanography, Volume 67, Issue 12, Page 2750-2762, December 2022., 2022 Abstract A recent study hypothesized that the near‐zero temperatures that generally prevail in Arctic waters negate the influence that different nitrogen (N) sources can otherwise have on the growth and elemental stoichiometry of marine micro‐algae. Here we test this hypothesis experimentally by evaluating how temperature (0–9°C) affects the growth and
