Surf smelt accelerate usage of endogenous energy reserves under climate change.
PLoS ONE, 2022 Surf smelt (Hypomesus pretiosus) are ecologically critical forage fish in the North Pacific ecosystem. As obligate beach spawners, surf smelt embryos are exposed to wide-ranging marine and terrestrial environmental conditions. Despite this fact, very few

Use of affinity analysis to guide habitat restoration and enhancement for the imperiled delta smelt
Endangered Species Research, 2020 Habitat restoration efforts in the upper San Francisco Estuary, including the Sacramento-San Joaquin Delta, California, move forward, despite a paucity of information on the environmental requirements of many targeted species.

Molecular Identification of the Nematode Eustrongylides ignotus in Mandarin Fish, Siniperca chuatsi
Aquaculture, Fish and Fisheries, Volume 5, Issue 6, December 2025.ABSTRACT Mandarin fish (Siniperca chuatsi) is a high‐value economic freshwater fish in China; however, the frequent occurrence of diseases threatens its production. To this end, we explored the impact of a nematode parasite newly found in the abdomen of mandarin fish collected from Pudong, Shanghai, China.

Marine mammal recovery is associated with the resurgence of a nematode parasite
Ecology, Volume 106, Issue 10, October 2025.Abstract As the oceans change, the abundance of parasites and the risk of infection to marine mammals may also be changing. Nematodes in the family Anisakidae can harm marine mammals, and recent studies have revealed a global increase in these parasites, but the cause is unknown.

Molecular Ecology Resources, Volume 25, Issue 7, October 2025.ABSTRACT We introduce a new software program, MaxTemp, that increases precision of the temporal method for estimating effective population size (Ne) in genetic monitoring programs, which are increasingly used to systematically track changes in global biodiversity.

Do Snow‐Adapted Prey Facilitate Coexistence of the Sierra Nevada Red Fox With Sympatric Carnivores?
Molecular Ecology, Volume 34, Issue 20, October 2025.ABSTRACT Specialist species in alpine ecosystems may be increasingly threatened by climate‐driven habitat loss and encroachment by generalist competitors. Ecological theory predicts that niche differentiation through dietary specialisation can facilitate coexistence with generalist competitors.

Embryo Ecology of the Pacific Surf Smelt, Hypomesus pretiosus (Pisces: Osmeridae) [PDF]
, 1987 A study of the ecology of developing embryos of the Pacific surf smelt, Hypomesus pretiosus, was conducted. Embryos were maintained in the laboratory at 7.6, 12.1, and 17.6°C and the time to specific embryonic stages determined.

Modification of the biological intercept model to account for ontogenetic effects in laboratory-reared delta smelt (Hypomesus transpacificus)* [PDF]
, 2007 We investigated age, growth, and ontogenetic effects on the proportionality of otolith size to fish size in laboratory-reared delta smelt (Hypomesus transpacificus) from the San Francisco Bay estuary.
