Planktivores and Plankton Dynamics: Effects of Fish Biomass and Planktivore Type [PDF]

Canadian Journal of Fisheries and Aquatic Sciences, 1992
We quantified the effects of planktivore biomass and planktivore type in an experimental mesocosm study of factorial design in which five levels of fish biomass (0–75 g/m3) were cross-classified with two plantivore types: filter-feeding gizzard shad (Dorosoma cepedianum) and visual-feeding bluegill (Lepomis macrochims).

Revolutionising Agricultural Sustainability: New ‘Furrow Tillage’ can Mitigate Short‐Term Soil‐to‐Atmosphere CO2 Flux and Promote Soil‐Plant‐Microbe Health

Advanced Science, EarlyView.
Furrow tillage resolves the conventional‐vs.‐no‐tillage trade‐off by simultaneously cutting CO2 efflux to 2.0–3.0 g C m−2 d−1 and unlocking high nutrient availability for the rice rhizosphere. This scalable agronomic solution strengthens soil health, enhances plant physiology, reshapes microbial metabolism, and shifts paddy systems toward a net ...

Harmonizing Rigidity and Flexibility: Embedding COF Quantum Dots Into Extracellular Matrix Gel as Carbon Monoxide Depot for Acoustically Triggered Time‐Programmable Anti‐Infective Therapy

Advanced Science, EarlyView.
A rigid‑flexible integrated CO depot is engineered by embedding rigid COFQDs into a flexible ECM gel network. The rigid framework enables high‑capacity CO storage and sonodynamic bacterial killing, while the flexible ECM gel controls sustained CO release, collectively eradicating multidrug‑resistant infection and promoting scarless healing.

The paradox of inverted biomass pyramids in kelp forest fish communities [PDF]

Proceedings of the Royal Society B: Biological Sciences, 2016
Theory predicts that bottom-heavy biomass pyramids or ‘stacks’ should predominate in real-world communities if trophic-level increases with body size (mean predator-to-prey mass ratio (PPMR) more than 1). However, recent research suggests that inverted biomass pyramids (IBPs) characterize relatively pristine reef fish communities.

Pyrazole‐Derived Antibacterial Compounds Effectively Treat Methicillin‐Resistant Staphylococcus Aureus Infections by Inhibiting Aspartate Transcarbamoylase

Advanced Science, EarlyView.
This study unveils a novel antibacterial mechanism against MRSA, in which the compound Py‐27 selectively targets and inhibits aspartate transcarbamoylase (ATCase), a key enzyme in pyrimidine synthesis. This inhibition disrupts DNA replication, induces oxidative damage, leading to potent bactericidal activity.

Growth of Pimelodus maculatus (Actinopterygii, Pimelodidae) in cages at different stocking densities [PDF]

Biotemas, 2009
This study aimed to evaluate the influence of densities 8, 32, 56 and 80 fish/m3 on the productive performance of Pimelodus maculatus in 1m3 cages installed in 0.19ha earthen ponds without water renewal, located on private property in Santo Amaro da ...

Estimation of fish abundance in the internal estuaries and coastal waters in the bays of southern Primorye on the data on catches of fixed nets

Известия ТИНРО, 2017
Coastal fishery develops in Primorye since 1990s because of negative changes in the resources for Russian fishing industry in the deep-water sea. One of the way to optimize the fish resources usage is introduction of passive fishing gears, as fixed nets.
