Amino Acids in the Natural Food Web of Global Fishponds: Way Forward for Precision Protein Feeding in Pond Cyprinid Aquaculture

open access: yesReviews in Aquaculture, Volume 18, Issue 4, September 2026.
ABSTRACT Natural food webs in freshwater pond ecosystems provide an important nutritional foundation for cyprinid aquaculture, yet information on their protein and amino acid composition remains fragmented. This review synthesized published data from 30 studies (1950–2026) reporting protein and indispensable amino acid (IAA) composition of freshwater ...

A Generalizable Tool for Predicting Developmental Phenology for Wild Ecotherms

open access: yesEcology and Evolution, Volume 16, Issue 8, August 2026.
Custom hatch timing models developed for four North American Lithobates frog species. Models are parameterized from Moore (1939). Panels (A, B) shows differential developmental rates under varying thermal regimes and G × E interactions. ABSTRACT Development in poikilothermic organisms is strongly temperature‐dependent, particularly during early life ...

Multitrophic alpha and beta diversity of lake plankton across Canada

open access: yesOikos, Volume 2026, Issue 8, August 2026.
Anthropogenic environmental changes impact freshwater biodiversity globally. While biodiversity assessments in freshwater environments have traditionally focused on individual groups of organisms or trophic levels, considering patterns of ‘multitrophic biodiversity' across the food web provides a more comprehensive view of anthropogenic impacts and ...

Structured machine learning modeling to support conservation of deep‐sea benthic biodiversity

open access: yesConservation Biology, Volume 40, Issue 4, August 2026.
Abstract Biodiversity monitoring programs need to deliver accurate, timely, and actionable predictions. To establish a predictive monitoring program for deep‐sea benthos of the Santos Basin, Brazil, we developed a two‐stage structured model that allowed comparison of biodiversity predictions obtained from environmental simulations (2M‐Sim).

The Movements of Copepoda

open access: yesJournal of Cell Science, 1899
ABSTRACT Since the time of Brady it has been generally supposed that amongst the Copepoda the most important locomotor organs were the antennules. This belief is categorically stated in Huxley’s text-book on ‘The Anatomy of Invertebrated Animals,’ p. 235.

The Spatiotemporal Patterns and Environmental Effects of Pelagic Communities in the Northwest Pacific Ocean Based on Sound Scattering Layer Descriptors

open access: yesEcology and Evolution, Volume 16, Issue 7, July 2026.
This study developed generalized additive models using SSL descriptors, providing an innovative approach for analyzing relationships between marine environmental variables and pelagic community distributions. ABSTRACT The sound scattering layer (SSL) plays an important role in maintaining the structure and functioning of marine ecosystems.

Dormancy in Copepoda.

open access: yesOceanography in Japan, 1998
Dormancy is a widespread phenomenon in Copepoda. It is known from free-living and bottom dwelling representatives of three copepod taxa, namely Harpacticoida, Cyclopoida, and Calanoida. There are 7 genera of Harpacticoida, 9 genera of Cyclopoida and 31 genera of Calanoida that exhibit dormancy in both marine and freshwaters.
