Accurate Identification of Key Groups of Microeukaryotes Using Multimodal Deep Learning: An Integrated Classification Model Combining Morphological and Molecular Data

Molecular Ecology Resources, Volume 26, Issue 6, August 2026.
ABSTRACT Traditional classification of flagellates (i.e., flagellated protists) relies on morphological traits or a single molecular marker, which suffer from subjectivity and limited data sources. This study proposes a multimodal deep learning model, Residual Multi‐Feature Attention‐50 (ResMFA50), that integrates photomicrographs and small subunit ...

Las Euglenófitas en las Tablas de Daimiel como ejemplo de las limitaciones de los indicadores biológicos de la degradación ambiental

Anales del Jardín Botánico de Madrid, 2005
Las Tablas de Daimiel National Park is a semiarid, hypertrophic wetland located in La Mancha (Ciudad Real, Central Spain). During the period 1996-2002 we carried out monthly samplings at three sites of Las Tablas. Thirty five taxa of Euglenophytes of the

A unique sessile loricate euglenid, Lepocinclis loricata sp. nov. (Euglenophyta, Phacaceae), from South Africa: Evolutionary implications

Journal of Phycology, Volume 62, Issue 3, Page 846-854, June 2026.
Abstract In this paper, we describe Lepocinclis loricata sp. nov. (Phacaceae), a sessile loricate euglenid that differs from all known loricate taxa by its unique combination of the presence of a lorica, monad morphology, sessile habit, and phylogenetic position within the Phacaceae. Populations of this species inhabit two turbid, silt‐rich waterbodies,

Algal and cyanobacterial diversity in saline rivers of the Elton Lake Basin (Russia) studied via light microscopy and next-generation sequencing

Biosystems Diversity, 2021
Naturally saline rivers are known in various regions of the world. Saline rivers with a salinity gradient from the source to the mouth are particularly interesting, because the range of salinity is the structure-forming factor of the hydrobiont ...

A Systematic Review of Biofloc Technology and Periphyton in Giant Freshwater Prawn (Macrobrachium rosenbergii) Aquaculture

Aquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
Biofloc technology and periphyton‐based systems enhance the sustainable production of giant freshwater prawn (Macrobrachium rosenbergii). A PRISMA‐guided review (2005 – 2024) shows that BFT improves survival (75 – 78 %) and feed efficiency, while periphyton supports natural productivity in grow‐out.

Effects of Formulated Feed and Forage Fish Feeds on Phytoplankton Community Structure in Mandarin Fish (Siniperca chuatsi) Culture Ponds

Aquaculture Research, Volume 2026, Issue 1, 2026.
The mandarin fish (Siniperca chuatsi) is an economically important carnivorous freshwater fish native to China. Recent studies have explored physiological adaptation mechanisms of mandarin fish to artificial feed. However, diverse feed regimes exerted distinct influences on the aquaculture water environment, and few reports have investigated the ...
