Sublethal Biochemical Effects of Polyethylene Microplastics and TBBPA in Experimentally Exposed Freshwater Shrimp Palaemonetes argentinus [PDF]
Biology, 2023 The biochemical effects of sublethal exposure to polyethylene microplastics (PEM) of 40–48 µm particle size and the flame retardant tetrabromobisphenol A (TBBPA), a plastic additive, on the freshwater shrimp Palaemonetes argentinus were assessed.

Population origin determines the adaptive potential for the advancement of flowering onset in Lupinus angustifolius L. (Fabaceae). [PDF]
Evol Appl, 2023 Abstract In the present framework of global warming, it is unclear whether evolutionary adaptation can happen quick enough to preserve the persistence of many species. Specifically, we lack knowledge about the adaptive potential of the different populations in relation to the various constraints that may hamper particular adaptations. There is evidence

Assisted Gene Flow Management to Climate Change in the Annual Legume <i>Lupinus angustifolius</i> L.: From Phenotype to Genotype. [PDF]
Evol ApplABSTRACT Climate change may hinder species' ability to evolutionarily adapt to environmental shifts. Assisted gene flow, introducing adaptive alleles into target populations, could be a viable solution for keystone species. Our study aimed to evaluate the benefits and limitations of assisted gene flow in enhancing the evolutionary potential of Lupinus ...

Does the dose make the poison? Neurotoxic insecticides impair predator orientation and reproduction even at low concentrations. [PDF]
Pest Manag Sci, 2022 Neurotoxic insecticides negatively affected the behavior and reproduction of the predator Nesidiocoris tenuis, even at low concentrations. Our study suggest that these compounds should be avoided when the presence of the predator is desirable. Abstract BACKGROUND Pesticides can be noxious to non‐target beneficial arthropods and their negative effects ...

Effects of a Dietary Multienzyme Extract on Isotope Biokinetics in Red Claw Crayfish Cherax quadricarinatus Juveniles. [PDF]
Aquac NutrUnderstanding the nutritional and metabolic physiology of aquatic organisms is essential for optimizing aquaculture practices and informing ecological models. We investigated the influence of dietary composition, specifically the incorporation of multienzyme extract derived from Pleoticus muelleri waste, on the growth and metabolic processes of ...
