Topic Modeling of Fatty Acid Studies: Evaluating Environmental Changes in Freshwater Ecosystems

open access: yesInternational Review of Hydrobiology, Volume 111, Issue 1, June 2026.
ABSTRACT Fatty acids (FAs) are biochemical molecules with vital structural and metabolic functions in all living organisms. Over the last decades, FA analysis in ecological studies has garnered significant attention due to its diverse applicability, such as taxonomic support for species identification, investigations on trophic interactions, and ...

Optimal adult growth of Daphnia in a seasonal environment [PDF]

open access: yes, 1993
1. The cladoceran Daphnia serves as an example of an iteroparous organism, with overlapping generations, that is capable of substantial adult growth. The life history of Daphnia was modelled as the consequence of a series of decisions about allocation of

Daphnias: from the individual based model to the large population equation [PDF]

open access: yes, 2012
The class of deterministic 'Daphnia' models treated by Diekmann et al. (J Math Biol 61: 277-318, 2010) has a long history going back to Nisbet and Gurney (Theor Pop Biol 23: 114-135, 1983) and Diekmann et al. (Nieuw Archief voor Wiskunde 4: 82-109, 1984).

Metabolite Profiling and Anticancer Evaluation of Iraqi Haloxylon articulatum Halophyte via LC–HRMS/MS, Molecular Docking, and ADMET Analysis

open access: yesChemistry &Biodiversity, Volume 23, Issue 2, February 2026.
This study investigates the phytochemical composition and biological activities of a hydroalcoholic extract of Haloxylon articulatum. LC‐HRMS/MS identified diverse bioactive compounds, notably N‐caffeoyltyramine and sinapoyltyramine. The extract exhibited strong antioxidant activity and significant cytotoxic effects against gastric cancer cell lines ...

Differential effects of freshwater browning across fish species: consequences for individual‐ to community‐level fish traits in north temperate lakes

open access: yesBiological Reviews, Volume 101, Issue 1, Page 128-146, February 2026.
ABSTRACT The browning of freshwater ecosystems is increasingly evident in temperate and northern regions, with widespread ramifications for lake physics, chemistry, and biology. Contrasting results on how freshwater browning may impact fish have been reported, but there has been no comprehensive examination of how browning may cause cascading effects ...
