Developing respirometry methodology for the Critically Endangered delta smelt

Endangered Species Research
Delta smelt Hypomesus transpacificus is a Critically Endangered fish native to the San Francisco Estuary. Respirometry methods quantify O 2 consumption (MO 2 ) to estimate metabolic activity, providing insights on

Seeing the Forest–Communities–Trees: Exploring the Impact of Industry Agglomerations on Technological Innovations and Firm Performance within Ecosystems

Journal of Management Studies, EarlyView.
Abstract Drawing on agglomeration theory, embeddedness theory, and the community assembly metaphor, this study examines how regional industrial ecosystems (RIEs) shape firm performance in China's manufacturing sector. Using longitudinal data on 1012 listed manufacturing firms across China between 2008 and 2019, we combine input–output analysis with ...

Fish assemblage at a newly restored tidal wetland reflects surrounding waterways in the Sacramento‐San Joaquin Delta

Restoration Ecology, EarlyView.
Abstract Introduction We studied the response of fish assemblages, water quality, and plankton following the completion of 700 acres of a 1184‐acre tidal restoration project (Dutch Slough Tidal Restoration; DSTR) in a system degraded by water diversions, channelization, non‐native species, and wetland loss.

Investigating the efficacy of tidal wetland restoration in enhancing aquatic food web resources for native fishes

Restoration Ecology, EarlyView.
Abstract Introduction Endangered fish species, such as Delta smelt (Hypomesus transpacificus), in the San Francisco Estuary are threatened by a multitude of anthropogenic stressors. Tidal wetland restoration can partially mitigate these stressors by increasing food availability of aquatic invertebrate prey, but the efficacy of restoration remains ...

Size, fecundity and condition factor changes in endangered delta smelt Hypomesus transpacificus over 10 generations in captivity

Aquaculture, Fish and Fisheries, 2023
The once abundant delta smelt Hypomesus transpacificus is now on the verge of extinction. At the UC Davis Fish Conservation and Culture Laboratory, a refuge population has been maintained since 2008 as a safeguard against extinction and to breed and ...

Silverside gold mine? Restored tidal habitats host abundant invasive fishes in a novel California marsh (U.S.A.)

Restoration Ecology, EarlyView.
Abstract Introduction Novel ecosystems, where environmental conditions have been fundamentally altered from a historic norm, require nontraditional approaches to restoration. Suisun Marsh, located within California's San Francisco Estuary (SFE), is a novel, brackish water wetland complex, where managers have begun restoring tidal connectivity to ...

Turbidity and Salinity Affect Feeding Performance and Physiological Stress in the Endangered Delta Smelt [PDF]

Integrative and Comparative Biology, 2013
Coastal estuaries are among the most heavily impacted ecosystems worldwide with many keystone fauna critically endangered. The delta smelt (Hypomesus transpacificus) is an endangered pelagic fish species endemic to the Sacramento-San Joaquin Estuary in northern California, and is considered as an indicator species for ecosystem health.

The heart responds to pressure via the lung: Dive depth alters cardiac control in bottlenose dolphins

The Journal of Physiology, EarlyView.
Abstract figure legend Dive depth independently modulated cardiac regulation in bottlenose dolphins during controlled voluntary dives. Dolphins performed dives to 0.5, 5 and 10 m with standardized dive durations, allowing the effects of depth on cardiovascular responses to be evaluated.

Design of a Three‐Phase PWM Rectifier Based on Improved Whale Optimization Algorithm Optimized Fuzzy Control

Advanced Control for Applications, Volume 8, Issue 3, September 2026.
Schematic diagram of the whale optimization algorithm (WOA)–optimized fuzzy proportional–integral–derivative (PID) controller. The WOA is employed to dynamically tune the scaling factor expressions and fuzzy control parameters (a(e)a(e), a(ec)a(ec), βpβp, βiβi), as well as the initial PID gains (kp0kp0, ki0ki0), based on the error (ee) and its ...
