Cognitive Symbionts. Expanding the Scope of Cognitive Science With Fungi

open access: yesTopics in Cognitive Science, EarlyView.
Abstract It has been argued that fungi have cognitive capacities, and even conscious experiences. While these arguments risk ushering in unproductive disputes about how words like “mind,” “cognitive,” “sentient,” and “conscious” should be used, paying close attention to key properties of fungal life can also be uncontroversially productive for ...

A tale of three kingdoms: Members of the Phylum Nematoda independently acquired the detoxifying enzyme cyanase through horizontal gene transfer from plants and bacteria [PDF]

open access: yes, 2018
Horizontal gene transfer (HGT) has played an important role in the evolution of nematodes. Among candidate genes, cyanase, which is typically found only in plants, bacteria and fungi, is present in more than 35 members of the Phylum Nematoda, but absent ...

Parasitic castration, growth, and sex steroids in the freshwater bonefish Cyphocharax gilbert (Curimatidae) infested by Riggia paranensis (Cymothoidea)

open access: yesNeotropical Ichthyology
Cyphocharax gilbert shows parasitic castration when infested by the crustacean Riggia paranensis, being unable to reproduce. Fish were sampled in the middle rio Itabapoana, Brazil, to study the prevalence of parasitism, growth, and sex steroid ...

Plant‐Derived Treatments for Monogenean Parasites in Farmed Fish: A Systematic Review and Meta‐Analysis

open access: yesReviews in Aquaculture, Volume 18, Issue 3, June 2026.
ABSTRACT Monogeneans are among the most problematic ectoparasites in finfish aquaculture. Plant‐derived compounds have been widely explored as therapeutic agents, yet their efficacy and safety have not been quantitatively synthesized across studies. This study provides a meta‐analysis of plant‐based treatments against monogeneans, integrating 453 in ...
