Pd(II) Complexes of Schiff Base Ligands Derived From 4‐Aminoantipyrine: Synthesis, Characterization, Crystal Structure and Acute Toxicity Evaluation

open access: yesChemistrySelect, Volume 11, Issue 1, 8 January 2026.
Palladium(II) complexes (1–6) with Schiff bases (HL1–HL6) were synthesized and characterized using different spectroscopic methods. The molecular structures of ligands HL1, HL3, HL6 and complexes 1, 2, 3, 6 were determined by X‐ray diffraction analysis. The toxicity of the compounds was assessed on both plant and animal cells.

Morphology and Ultrastructure of cysts in different species of the brine shrimp, Artemia from Southern India

open access: yesInternational Journal of Aquatic Biology, 2013
Surface topography and ultrastructure of dried cysts of Artemia parthenogenetica (Vedaranyam population) and bisexual Artemia sp. (Kelambakkam population) were studied electron microscopically in order to identify the bisexual strain, inhabiting Covelong

Functional Role of Native and Invasive Filter-Feeders, and the Effect of Parasites: Learning from Hypersaline Ecosystems.

open access: yesPLoS ONE, 2016
Filter-feeding organisms are often keystone species with a major influence on the dynamics of aquatic ecosystems. Studies of filtering rates in such taxa are therefore vital in order to understand ecosystem functioning and the impact of natural and ...

Ecotoxicology of Mercerized Cellulose–Treated Tannery Effluents Using Salvinia auriculata (Salviniaceae) as a Bioindicator

open access: yesEnvironmental Toxicology, Volume 40, Issue 12, Page 1358-1374, December 2025.
ABSTRACT Given the growing concern over the environmental impacts of industrial effluents, particularly from tanneries, assessing the ecotoxicological risks associated with these effluents, even after remediation treatments, is crucial. Therefore, we aimed to evaluate the potential effects of exposure to raw and treated tannery effluents with ...

Effect of the enrichment time with the tuna orbital oil emulsion on the fatty acids profile of juveniles of Artemia franciscana

open access: yesAquaculture and Fisheries, 2021
Artemia is deficient in polyunsaturated fatty acids (PUFAs), particularly in arachidonic (ARA, 20:4n-6), eicosapentaenoic (EPA, 20:5n-3), and docosahexaenoic acid (DHA, 22:6n-3). The aim of this study was to determine the optimal time in which the higher

Identification of the alternative oxidase gene and its expression in the copepod Tigriopus californicus [PDF]

open access: yes, 2019
In addition to the typical electron transport system (ETS) in animal mitochondria responsible for oxidative phosphorylation, in some species there exists an alternative oxidase (AOX) pathway capable of catalyzing the oxidation of ubiquinol and the ...

Response to bidirectional selection for naupliar length in Artemia franciscana [PDF]

open access: yes, 2003
Bidirectional mass selection for naupliar length was practised in Artemia franciscana fromGreat Salt Lake, UT, USA, with the aim of developing two divergent lines, namely small naupliar size (SNS) and bigger naupliar size (BNS). A random-bred control

Sexual conflict as a constraint on asexual reproduction: an empirical review

open access: yesBiological Reviews, Volume 100, Issue 6, Page 2681-2706, December 2025.
ABSTRACT Theory predicts that facultatively asexual animals, which can leverage the advantages of both sexual and asexual reproduction, should outcompete obligately sexual and obligately asexual animals. Yet, paradoxically, obligate sexual reproduction predominates in many animal lineages, while the most flexible form of facultative asexuality (i.e ...

Intercalibration of ecotoxicity testing protocols with Artemia franciscana

open access: yesEcological Indicators, 2015
The brine shrimp, Artemia spp., is widely used in ecotoxicology as a target biological model. Although several protocols were available in the early 1980s, only the 24-h acute mortality toxicity test was evaluated in a European intercalibration exercise during that period.

Species Diversity and Distribution of Artemia (Crustacea, Anostraca) in Iran: Historical Contexts and Updated Review

open access: yesZoodiversity
In light of the pivotal role of Artemia Leach, 1819 as food in larviculture and fisheries, it becomes imperative to continually reassess its resources and deepen our understanding of its species diversity.
