Comment: Food web interactions and biomanipulation in Australian reservoirs [PDF]
The authors have been studying the control of phytoplankton biomass in several Australian reservoirs. To manipulate fish communities in order to reduce phytoplankton biomass, one needs a thorough understanding of processes in the plankton-associated food

This study reveals that Urolithin A (UA) counteracts alcohol‐induced cognitive and social dysfunction (AICSD) via a gut microbiome‐dependent mechanism. UA‐enriched Bacteroids sartorii and Parabacteroids distasonis elevate anandamide (AEA), which activates the CB1R‐DRD2‐Rap1 signaling cascade to drive synaptic repair and reduce neuroinflammation ...

Environmental DNA (eDNA) is a cost‐efficient, noninvasive method to monitor fish populations, but the quantitative aspect of this technique (e.g., estimating biomass or densities) remains underexplored.

Microalgae have high nutritional values for aquatic organisms compared to fish meal, because microalgae cells are rich in proteins, lipids, and carbohydrates. However, the high cost for the commercial production of microalgae biomass using fresh water or

Resilient and rapid recovery of native trout after removal of a non‐native trout
While the importance of reducing impacts of non‐native species is increasingly recognized in conservation, the feasibility of such actions is highly dependent upon several key uncertainties including stage of invasion, size of the ecosystem being ...

Status of the Pacific Mackerel resource during 1996 management recommendations for the fishery [PDF]
The California fishery for Pacific mackerel (Scomber japonicus) has declined precipitously since 1990. Statewide landings during 1995 continued the downward trend, and totaled only 9,185 short tons.

Western Antarctic fish species and biomass diversity
Of the 168 fish species living in the Western Antarctic, 104 species belonging to 20 families occur in the South Shetland area: 39 species from 10 families have been found in the Admiralty Bay, 91 species (29 families) in theSouth Georgia area; the South Orkney region hosts 74 species from 18 families while the near Antarctic Peninsula shelf 71 species

Recruitment-driven fish production in two regions where fish biomass has drastically declined
Abstract Catches have remained relatively high in the Gulf of Thailand and the Bohai Sea, China, despite severe biomass declines (around 95%) evidenced by fishery-independent surveys. Such high production at very low stock sizes is not predicted by simple-surplus production theory, but can be explained by age-structured models that ...

Generalized Mechanism Model for Ecosystem Hysteresis
A simplified model examines ecosystem transitions into alternative states after disturbances by leveraging positive and negative feedbacks. It identifies critical tipping points and quantifies hysteresis. Tests conducted on lakes, grasslands, and pitcher‐plant leaves align closely with empirical data and enable the prediction of recovery trajectories ...

Global analysis of benthic complexity in shallow coral reefs
Three-dimensional shallow benthic complexity (also known as benthic rugosity) reflects the physical conditions of shallow coral reefs environments and can be used to estimate fish biomass and coral cover on reefs.
