Rapid responses of marsh birds to large‐scale tidal wetland restoration in California's Sacramento–San Joaquin Delta

Restoration Ecology, EarlyView.
Abstract Introduction Tidal wetland restoration is widely used to recover ecosystem function in modified estuaries, yet uncertainty remains about how quickly wildlife communities respond. Early trajectories are central to evaluating restoration success, guiding adaptive management, and building ecosystem resilience in engineered landscapes. Marsh birds

Will Tidal Wetland Restoration Enhance Populations of Native Fishes?

San Francisco Estuary and Watershed Science, 2003
Restoration of tidal wetlands might enhance populations of native fishes in the San Francisco Estuary of California. The purpose of this paper is to: (1) review the currently available information regarding the importance of tidal wetlands to native ...

Contrasting migratory chronology and routes of Lesser Scaup: implications of different migration strategies in a broadly distributed species

Journal of Field Ornithology
Migration allows birds to improve fitness by exploiting seasonal resource peaks and avoiding limitations. Migration strategies may differ among individuals within a species, but for all strategies, the benefit of increased fitness should outweigh the ...

Open Ocean Biogeochemical Impacts of Extreme Terrestrial Precipitation

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Extreme events reshape ocean ecosystems with significant implications for nutrient and carbon cycling. Here, we demonstrate that flooding on land can be a significant driver of biogeochemical variability in the open ocean, even in relatively dry climates.

High and minimally variable adult marine survival among multiple stocks of Chinook salmon

Ecosphere, Volume 17, Issue 9, September 2026.
Abstract Estimates of individual survival across space and time provide critical information on processes that regulate population abundance. Here, we use state‐space models fit to data from more than 500 acoustically tagged Chinook salmon to better understand the factors that shape survival during the final summer and fall of marine residence—a life ...

New observations and corrections concerning the trio of invasive hydromedusae Maeotias marginata (=M. inexpectata), Blackfordia virginica, and Moreisia sp. in the San Francisco Estuary

Scientia Marina, 2000
New observations of Maeotias, Blackfordia, and Moerisia in low salinity waters of the San Francisco Bay estuary allow better understanding of the life cycles and natural history of these three genera of invading hydrozoans.

Delineating incised stream sediment sources within a San Francisco Bay tributary basin [PDF]

Earth Surface Dynamics, 2016
Erosion and sedimentation pose ubiquitous problems for land and watershed managers, requiring delineation of sediment sources and sinks across landscapes.

Elusive and vulnerable: evaluating spatial and temporal variation in the distribution of manta rays around O’ahu using environmental DNA

Frontiers in Marine Science
Reef mantas (Mobula alfredi) around the Hawaiian Islands are vulnerable to extinction due to the low genetic diversity and resident populations that exhibit limited migration between islands.

Nutritional content of phytoplankton communities under ice

Ecosphere, Volume 17, Issue 9, September 2026.
Abstract The effects of winter environmental conditions on lake ecology can be highly variable. Ice and overlying snow isolate the water below, impeding exchange of materials among water, atmosphere, and the watershed. Even with these limitations, biological communities under the ice can persist, where cold‐tolerant taxa can be especially abundant ...
