Primary Production in the Delta: Then and Now

San Francisco Estuary and Watershed Science, 2016
doi: http://dx.doi.org/10.15447/sfews.2016v14iss3art1To evaluate the role of restoration in the recovery of the Delta ecosystem, we need to have clear targets and performance measures that directly assess ecosystem function.

Seasonal Differences in Migration Routes and Stopover Use of Greater Sand Plovers Between Mongolia and the Beibu Gulf Revealed by GPS Tracking

Ecology and Evolution, Volume 16, Issue 7, July 2026.
GPS‐GSM tracking of Greater Sand Plovers along the East Asian‐Australasian Flyway revealed seasonal differences in migration routes and stopover allocation between the northern Beibu Gulf and Mongolia. Spring northward migration was associated with a higher travel‐to‐stopover ratio, whereas autumn southward migration involved a greater proportion of ...

The molecular ecology of Microcystis sp. blooms in the San Francisco Estuary

Environmental Microbiology, 2017
Summary Harmful blooms of the cyanobacterium Microcystis sp. have become increasingly pervasive in the San Francisco Estuary Delta (USA) since the early 2000s and their rise has coincided with substantial decreases in several important fish species.

The Complete Mitogenome of the Estuarine Clam Potamocorbula amurensis (Corbulidae, Myida) and Its Implications for Phylogeny and Adaptation

Ecology and Evolution, Volume 16, Issue 7, July 2026.
This study reports the first complete mitogenome of the estuarine clam Potamocorbula amurensis, revealing its phylogenetic position as a sister group to the Myidae–Dreissenidae clade. Molecular dating indicates a Middle Jurassic divergence, and positive selection was detected in the nad5 gene, suggesting mitochondrial adaptations to osmotic stress in ...

Surface complexity and gastropod exclusion drive colonization of an intertidal eco‐engineered structure

Journal of Applied Ecology, Volume 63, Issue 7, July 2026.
Habitat complexity and grazing by invertebrate molluscs shaped community structure and ecosystem functioning on eco‐engineered substrates through distinct mechanisms. Increasing structural complexity increased invertebrate species richness with limited effects on macroalgae and carbon flux, while grazer exclusion had strong effects on macroalgal ...

The Delta as Changing Landscapes

San Francisco Estuary and Watershed Science, 2016
doi: http://dx.doi.org/10.15447/sfews.2016v14iss2art9What happens at one place in a landscape influences and is influenced by what happens in other places. Consequently, management and restoration that focus on individual places may fail to recognize and

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 ...

Sex Determination in Sponges

Molecular Reproduction and Development, Volume 93, Issue 6, June 2026.
ABSTRACT Sex determination in Porifera remains one of the least understood aspects of early metazoan biology despite the group's key phylogenetic position. Sponges display exceptional diversity in sexual systems—ranging from stable gonochorism to sequential hermaphroditism and sex reversal—yet lack morphological dimorphism and any discrete gonadal ...
