Divergent Thermal Habitat Responses to Climate Forcing in Shallow and Deep Lakes: The Role of Solar Radiation

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 7, July 2026.
Abstract Climate warming is expected to reduce thermal habitat for cold‐water fishes, yet the magnitude and direction of habitat change may depend on interactions among multiple climatic drivers. We analyzed two contrasting lakes in the same region—Lake Kasumigaura (a shallow, eutrophic lake) and Lake Inawashiro (a deep, oligotrophic lake)—to clarify ...

eDNA Metabarcoding Identifies Fish Conservation Priorities in Deep‐Water Fjords of British Columbia, Canada

Conservation Letters, Volume 19, Issue 3, May/June 2026.
ABSTRACT Fjords are deep‐water estuaries that support a wide range of marine habitats for pelagic fish. Yet, knowledge gaps in fish distribution and habitat use limit the implementation of efficient marine conservation strategies within fjords. Using five British Columbia fjords as a case study, we demonstrated that eDNA metabarcoding combined with ...

Developmental staging and salinity tolerance in embryos of the delta smelt, Hypomesus transpacificus

Aquaculture, 2019
Delta smelt (Hypomesus transpacificus) is a critically endangered species endemic to the San Francisco Bay Delta (SFBD). Important for the conservation of this species is understanding the physiological and ecological impacts contributing to their population decline, and current studies lack information on embryonic development.

Lag in Effective Population Size Decline Amid Demographic Collapse: A Case Study of the Delta Smelt (Hypomesus transpacificus)

Molecular Ecology, Volume 35, Issue 10, May 2026.
ABSTRACT Effective population size (Ne), census size (Nc) and their ratio (Ne/Nc) are widely used indicators in conservation genetics, yet long‐term empirical data tracking of all three metrics over long time scales in wild populations remains rare. Using monitoring data from 1995 to 2020, we examined temporal dynamics of Ne, Nc and their relationship ...

Identifying Environmental Factors Limiting Recovery of an Imperiled Estuarine Fish

Frontiers in Ecology and Evolution, 2022
Correctly identifying the environmental factors that limit population growth and recovery of imperiled species is an essential element of any targeted conservation program.

Observations on Food-organisms of a Teleost, Hypomesus olidus Pallas

NIPPON SUISAN GAKKAISHI, 1935
Observations were made from August, 1933 to July, 1934 on the content of alimentary canal of a teleost, Hypomesus olidus, and plankton organisms living in its habitat, Lake Kasumigaura Pref. Ibaraki. The fish feeds mostly on such kinds of small animals as are found most abundantly in the lake.

The effects of scientific uncertainty and values trade‐offs on flow management decisions for an endangered fish

Ecosphere, Volume 17, Issue 3, March 2026.
Abstract Consumptive use of freshwater is of concern in many estuarine ecosystems, and various frameworks have been used to prescribe environmental flows to benefit native species. However, few of these frameworks explicitly examine the potential trade‐offs between socioeconomic and conservation‐oriented values.

Locating Little Larvae: Environmental DNA Methods Can Detect a Rare Fish Species Under Field Estuarine Conditions

Environmental DNA, Volume 8, Issue 2, March/April 2026.
We measured a positive linear relationship between eDNA concentration and abundance for larval Delta Smelt (Hypomesus transpacificus) with N = 1 larva exceeding the limit of detection for the novel qPCR assay. Field experiments quantified the probability of detection for eDNA sampling methods at known abundances and distances from source. ABSTRACT Rare
