Artemia salina Toxicity Assay: Standardization in a 24‐Well Microplate
Environmental Toxicology, EarlyView.ABSTRACT Bioassays with Artemia sp. are widely used in aquatic, environmental, and human toxicology as an initial tool to investigate the toxicity of plant extracts, isolated compounds, drugs, and products of natural or synthetic origin. These assays allow for the estimation of the median lethal concentration (LC50) and guide subsequent studies in ...

Meal or mate: Exploring the evidence of sexual cannibalism among amphibians
Ecology and EvolutionActive forms of cannibalism that involve predation of live conspecifics occur widely among amphibians, most notably by tadpoles that feed on each other and adults that feed on juveniles.

Isogroup Selection to Optimize Biocontrol Increases Cannibalism in Omnivorous (Zoophytophagous) Bugs
Insects, 2017 Zoophytophagous insects can substitute animals for plant resources when prey is scarce. Many arthropods feed on conspecifics to survive in these conditions.

Metformin Attenuates Behavioral Deficits and Oxidative Stress in a Preclinical Model of Autism. [PDF]
Dev NeurobiolABSTRACT Autism spectrum disorder (ASD) is a complex neurodevelopmental condition lacking effective pharmacological treatments. Metformin has emerged as a candidate for drug repurposing in ASD due to its metabolic and neurobiological actions. This study evaluated the in vivo effects of metformin (400 mg/kg, orally) administered from postnatal day 21 to

Effects of Density and Food Availability on the Growth of Captive‐Reared Eastern Hellbenders
Zoo Biology, EarlyView.Our experiments demonstrate that food is the major factor limiting captive‐reared Hellbender growth and that increasing rearing density to the tested levels does not negatively impact growth. Implementing these changes may result in larger, more robust Hellbenders and increase the success of reintroduction programs.

Fitness consequences of cannibalism in the fall armyworm, Spodoptera frugiperda
, 1999 We investigated the consequences of cannibalism for some correlates of fitness in the fall armyworm, Spodoptera frugiperda (Lepidoptera: Noctuidae). The benefits gained by cannibals were ascertained by comparing survival, development rate, and pupal ...

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Soil food web models are essential for linking animal diversity to carbon and nutrient cycling. However, it is unclear how soil animals regulate excess carbon when nutrient availability limits their growth and how to best represent animal respiration in these models. To

Insects, 2020 Cannibalism in insects plays an important role in ecological relationships. Nonetheless, it has not been studied as extensively as in other arthropods groups (e.g., Arachnida).

Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant–herbivore interactions are typically examined through plant defence and herbivore performance, yet individual herbivore behavioural mechanisms underlying these interactions are rarely considered alongside plant traits.

Revista FAMECOS, 2008 Dans ce sens, on peut même dire que l’hégémonie met fin à la domination(La domination se caractérise par la relation maître / esclave - qui est encore une relation duelle, avec un potentiel d’aliénation, de rapports de force et de conflits). Nous intériorisons l’Ordre mondial et son dispositif opérationnel, dont nous sommes les otages bien plus que les
