Feeding habits and novel prey of larval fishes in the northern San Francisco Estuary

open access: yesEnvironmental DNA, 2021
Food limitation can dampen the survival and growth of fish species during early development. To investigate prey diversity important to the planktivorous larval longfin smelt (Spirinchus thaleichthys) and Pacific herring (Clupea pallasii) from the San ...

Temporal and spatial variation in population structure among brooding sea stars in the genus Leptasterias

open access: yesEcology and Evolution, 2021
Temporal genetic studies of low‐dispersing organisms are rare. Marine invertebrates lacking a planktonic larval stage are expected to have lower dispersal, low gene flow, and a higher potential for local adaptation than organisms with planktonic ...

Using Satellite AIS to Analyze Vessel Speeds Off the Coast of Washington State, U.S., as a Risk Analysis for Cetacean-Vessel Collisions

open access: yesFrontiers in Marine Science, 2020
Most species of whales are vulnerable to vessel collisions, and the probability of lethality increases logistically with vessel speed. An Automatic Identification System (AIS) can provide valuable vessel activity data, but terrestrial-based AIS has a ...

Age‐ and sex‐related dietary specialization facilitate seasonal resource partitioning in a migratory shorebird

open access: yesEcology and Evolution, 2021
Dietary specialization is common in animals and has important implications for individual fitness, inter‐ and intraspecific competition, and the adaptive potential of a species. Diet composition can be influenced by age‐ and sex‐related factors including

Ontogeny influences sensitivity to climate change stressors in an endangered fish. [PDF]

open access: yes, 2014
Coastal ecosystems are among the most human-impacted habitats globally, and their management is often critically linked to recovery of declining native species.

Interactions Between Temperature Variability and Reproductive Physiology Across Traits in an Intertidal Crab

open access: yesFrontiers in Physiology, 2022
Thermal extremes alter population processes, which can result in part from temperature-induced movement at different spatial and temporal scales. Thermal thresholds for animal movement likely change based on underlying thermal physiology and life-history

Delivering Food to Hungry Fish in the San Francisco Estuary [PDF]

open access: yesFrontiers for Young Minds, 2021
The San Francisco Estuary is home to an important endangered fish called delta smelt. Delta smelt eat small, nutritious animals called zooplankton to survive and grow. In turn, zooplankton grow by eating microscopic plant-like organisms called phytoplankton. In the past, the Estuary was full of plankton and delta smelt.

Application of a New Shore-Based Vessel Traffic Monitoring System Within San Francisco Bay

open access: yesFrontiers in Marine Science, 2020
Vessel traffic management systems can be employed for environmental management where vessel activity may be of concern. One such location is in San Francisco Bay where a variety of vessel types transit a highly developed urban estuary. We analyzed vessel

Assessments at multiple levels of biological organization allow for an integrative determination of physiological tolerances to turbidity in an endangered fish species. [PDF]

open access: yes, 2016
Turbidity can influence trophic levels by altering species composition and can potentially affect fish feeding strategies and predator-prey interactions.
