Apparent kleptoparasitism in fishparasitic gnathiid isopods

, 2019
Gnathiid isopods are common external parasites/micropredators that feed on the blood of marine fishes. During the course of processing samples of gnathiid isopods collected from light traps in the central Philippines, we observed a gnathiid attached to ...

Discovery and Fine‐Scale Mapping of Hadal Xenophyophore Habitat in the Nova Canton Trough, Central Pacific Ocean

Remote Sensing in Ecology and Conservation, EarlyView.
Discovery and fine‐scale mapping of a hadal xenophyophore field: submersible video transects and photogrammetry enable semi‐automated delineation of xenophyophores, revealing their abundance, spatial organisation, structural complexity and contribution to habitat heterogeneity at ~8000 m depth.

Trace Levels of Triclosan May Affect Root Growth and Morphology in Cultivated Plants

Environmental Toxicology, EarlyView.
ABSTRACT Triclosan (TCS) is a micropollutant frequently detected in biosolids applied to agricultural soils. In soil solution—where it is potentially bioavailable to roots—it occurs at residual concentrations (ng L−1). Nevertheless, the ecotoxicological implications of TCS exposure in agricultural crops at these concentrations are still not fully ...

Terrestrial Isopods as Biotic Generators of Microplastics Following Chronic Exposure to Weathered Low‐Density Polyethylene

Environmental Toxicology, EarlyView.
ABSTRACT Terrestrial detritivores such as isopods and springtails play a vital role in cycling nutrients through soil ecosystems. Microplastics (MPs, < 5 mm) are increasingly recognized as contaminants of terrestrial soils, yet little is known about whether soil invertebrates themselves are impacted by consuming these plastics or if they can generate ...

Adaptations of Terrestrial Isopods to Varying Wavelengths of Light [PDF]

, 1976
30 leaves. Advisor: Dr. Rodney RogersThe problem. The purpose of this investigation was to determine the response of terrestrial isopods that were subjected to prolonged periods of varying wavelengths of light, and to measure this adaptability by ...

Geographic Patterns of Head Morphology in Syngnathus typhle Across Marine Regions

Integrative Zoology, EarlyView.
Morphometric analysis of Syngnathus typhle head shape shows distinct geographic patterns across Baltic, North, Atlantic, and Mediterranean marine regions, driven by variation in snout length, head depth, and eye position. Findings provide a non‐invasive baseline for conservation monitoring.

Isopod parasites of Pygocentrus piraya (Characiformes: Serrasalmidae) in the lower São Francisco River, Brazil [PDF]

Nauplius
Isopods of the suborder Cymothoida include ectoparasite species that cause physical damage and affect the development of the host by feeding on blood and tissues.

Osteological, Biological, and Genetic Consequences of Colonization of Fresh Waters by Marine Cottoid Fishes (Cottidae)

Integrative Zoology, EarlyView.
Lacustrine forms of Triglopsis from North American and European lakes are at different stages of evolution, making them a suitable model for testing hypotheses about evolutionary patterns and rates. An integrative analysis of morphological, genetic, and biological adaptations occurring in lacustrine forms of the genus Triglopsis was carried out.

Toxicity of the organophosphorous insecticide chlormephos to the earthworm Eisenia andrei and the terrestrial isopod Porcellio scaber

Acta Biologica Slovenica, 2009
In the present study we determined the toxicity of chlormephos to two common soil organisms – earthworms (Eisenia andrei) and isopods(Porcellio scaber) using Lufa 2.2 soil.

DeepZoo: A cost‐effective and modular sampler for ecological studies in the deep ocean

Methods in Ecology and Evolution, EarlyView.
Abstract Understanding the structure and dynamics of deep‐ocean communities requires effective sampling of pelagic organisms in near‐bottom waters. These dispersive organisms contribute to biodiversity, connectivity and ecosystem recovery. Yet, current sampling methods remain constrained by size, cost, and depth, leaving key questions unanswered in ...
