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.

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.

Predators of the Invasive Mussel Musculista senhousia (Mollusca: Mytilidae) [PDF]
, 2002 Musculista senhousia (Benson in Cantor, 1842) is a soft sediment-dwelling mussel that has spread anthropogenically from its native Asia to North America, Australasia, and Europe.

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.

Spatiotemporal Models of an Estuarine Fish Species to Identify Patterns and Factors Impacting Their Distribution and Abundance [PDF]
, 2018 Understanding the distribution and abundance of organisms can be exceedingly difficult for pelagic fish species that live in estuarine environments. This is particularly so for fish that cannot be readily marked and released or otherwise tracked, such as

Spatially dynamic abundance patterns for a rare fish species
Ecosphere, Volume 16, Issue 7, July 2025.Abstract Recovery of rare and imperiled species is often supported by targeting the dynamic drivers of abundance patterns. However, knowledge of these drivers can be obscured by challenges stemming from species detectability and autocorrelated data. Longfin Smelt (Spirinchus thaleichthys) in the San Francisco Bay‐Delta have become rare as the result of

Migration behavior of PGCs and asymmetrical gonad formation in pond smelt Hypomesus nipponensis
The International Journal of Developmental Biology, 2017 In teleost fish, the gonad originates from primordial germ cells (PGCs) and somatic cells. However, it is not clear whether the final gonadal position is determined by anteroposterior and dextrosinistral differentiation of endodermal organs or by the distribution of PGCs.

Molecular Ecology Resources, Volume 25, Issue 5, July 2025.Abstract Accurate taxonomic identification is foundational for effective species monitoring and management. When visual identifications are infeasible or inaccurate, genetic approaches provide a reliable alternative. However, these approaches are sometimes less viable (e.g., need for near real‐time results, remote locations, funding concerns, molecular
