Consequences of temperature and temperature variability on swimming activity, group structure, and predation of endangered delta smelt [PDF]

, 2019
The effects of water temperature on individual and group movement behaviour in prey fish can affect ecological interactions such as competition and predation, but how variability in temperature influence fish behaviour is less understood.

Murky Mysteries of Young Lamprey in the San Francisco Estuary

Frontiers for Young Minds, 2022
Early one morning, a scientist collecting fish in the San Francisco Estuary was surprised to find a young lamprey. She knew lamprey were ancient fish without jaws, bones, or scales, and she wondered to herself: Where else are young lamprey in the estuary?

An assessment of future tidal marsh resilience in the San Francisco Estuary through modeling and quantifiable metrics of sustainability

Frontiers in Environmental Science, 2022
Quantitative, broadly applicable metrics of resilience are needed to effectively manage tidal marshes into the future. Here we quantified three metrics of temporal marsh resilience: time to marsh drowning, time to marsh tipping point, and the probability

Non-indigenous hydromedusae in California's upper San Francisco Esturary: life cycles, distribution, and potential environmental impacts

Scientia Marina, 2000
Two species of hydromedusae, assumed to be native to the Black and Caspian Seas, were routinely collected in Suisun Slough, California, at the Suisun City Marina, during late summer and fall of 1997.

Characterization of plankton from the Galveston estuary [PDF]

, 1992
The purpose of this report is to summarize the published studies on phytoplankton and zooplankton in the Galveston Estuary. Before this project had begun, it was determined that there was insufficient long term data on plankton in the Galveston Estuary ...

Multistressor Interaction of Perfluorooctane Sulfonate (PFOS) and Temperature in Two Estuarine Fish Species, Red Drum (Sciaenops ocellatus) and Sheepshead Minnow (Cyprinodon variegatus)

Environmental Toxicology, EarlyView.
ABSTRACT Perfluorooctane sulfonate (PFOS), a perfluoroalkyl substance (PFAS), is characterized by a long, fluorinated carbon chain which makes it ideal for oil‐ and water‐repellent products but detrimental for the environment, where it persists and accumulates in organisms.

Patterns in bird and pollinator occupancy and richness in a mosaic of urban office parks across scales and seasons

Ecology and Evolution
Urbanization is a leading cause of global biodiversity loss, yet cities can provide resources required by many species throughout the year. In recognition of this, cities around the world are adopting strategies to increase biodiversity.

Climate change and the Delta, San Francisco Estuary and Watershed Science [PDF]

, 2016
Anthropogenic climate change amounts to a rapidly approaching, “new” stressor in the Sacramento–San Joaquin Delta system. In response to California’s extreme natural hydroclimatic variability, complex water-management systems have been developed, even as

Fish Love Floods: Benefits of Floodplains in San Francisco Estuary

Frontiers for Young Minds, 2022
Lots of rain can make rivers rise, causing them to spill into low-lying areas called floodplains. Floodplains protect cities from flooding and provide food-rich, safe habitats for freshwater creatures. The largest floodplain of the San Francisco Estuary is the Yolo Bypass. The Yolo Bypass is connected to the Sacramento River and protects Sacramento and

Sensory Biology of the Franciscana (Pontoporia blainvillei, Pontoporiidae, Cetartiodactyla): Ontogenetic Modifications of Vibrissae and Vibrissal Crypts

Integrative Zoology, EarlyView.
The transition of cetaceans from a terrestrial to an aquatic environment involved a crucial sensory adaptation to environments with limited visibility. Vibrissae, important mechanoreceptors, undergo an ontogenetic transformation in odontocetes. This research describes the histomorphology of vibrissae and crypts at different developmental stages ...
