Periphyton and Benthic Macroinvertebrate Response to Antimycin Piscicide During Brook Trout Restoration

open access: yesAquaculture, Fish and Fisheries, Volume 6, Issue 2, April 2026.
ABSTRACT The piscicide antimycin has been used as an effective fish toxicant to eradicate nuisance fishes because it is not as detectable by fish as other chemical piscicides. We evaluated the effects of antimycin and its detoxicant, potassium permanganate, on periphyton and benthic macroinvertebrates during a brook trout (Salvelinus fontinalis ...

Graman Revisited Once Again: A Reanalysis of the Late Holocene Legacy Faunal Assemblage From GB4 Rockshelter, New South Wales

open access: yesArchaeology in Oceania, Volume 61, Issue 1, Page 199-220, April 2026.
ABSTRACT The archaeological site Graman B4 provided one of the first records of substantial dietary change in ancient Australian Aboriginal society. Initial examination of the faunal remains from this site suggested that Late Holocene hunters reduced their focus on high‐ranked kangaroos to increasingly rely on arboreal possums; and that these ...

Current ecological understanding of fungal-like pathogens of fish: what lies beneath? [PDF]

open access: yes, 2014
Despite increasingly sophisticated microbiological techniques, and long after the first discovery of microbes, basic knowledge is still lacking to fully appreciate the ecological importance of microbial parasites in fish. This is likely due to the nature

Insights Into Spatial Orientation and Cognition in Tarantulas (Araneae: Theraphosidae) Under Natural Conditions, With Notes on Possible Ontogenetic Niche Shifts

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
Cognitive studies on spiders have largely ignored mygalomorphs, such as tarantulas, and almost completely lack field‐based observations. We present nine observations of arboreal and fossorial New World tarantulas, including a blind cave‐dwelling species, providing evidence for possible experience‐based navigation and spatial learning during foraging ...

A Novel Light‐Induced Collective Circular Movement in Armadillo sordidus Isopods

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
We describe an interesting aggregative behavior in terrestrial isopods. We conclude that this behavior is in response to intense artificial lighting. ABSTRACT Collective movement in terrestrial isopods has rarely been documented and almost never discussed.
