Multi-objective optimization shapes ecological variation [PDF]

open access: yes, 2013
Ecological systems contain a huge amount of quantitative variation between and within species and locations, which makes it difficult to obtain unambiguous verification of theoretical predictions.

Evaluation of the Dual Impact of Nanotechnologies on Health and Environment Through Alternative Bridging Models

open access: yesAdvanced Healthcare Materials, EarlyView.
This review explores how alternative invertebrate and small‐vertebrate models advance the evaluation of nanomaterials across medicine and environmental science. By bridging cellular and organismal levels, these models enable integrated assessment of toxicity, biodistribution, and therapeutic performance.

Mechanisms of Aristolochic Acid Resistance in Specialist Butterflies and Evolutionary Insights for Potential Protective Pathways

open access: yesAdvanced Science, EarlyView.
The study provides an extreme example of insect adaptation to highly toxic defenses of host plants, and investigates the complex strategies to resist carcinogenic aristolochic acids, including physical isolation, metabolic detoxification, and DNA repair.

Gut Microbe‐Driven Resistance Mechanisms in Propylea Japonica: Insights from Horizontal Gene Transfer and Oxidative Phosphorylation

open access: yesAdvanced Science, EarlyView.
Acinetobacter regulates dinotefuran tolerance in Propylea japonica by mediating the expression of the horizontally transferred gene PjDUF1. Abstract Insect–microbial symbiont relationships are widespread in nature and often involve lateral gene transfer.

Polyphenol diet and exercise as neuroprotective factors in a Drosophila model of Alzheimer's disease

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Moderate exercise and low‐dose ellagic acid supplementation improved motor performance, learning, and longevity in a transgenic Drosophila model of Alzheimer's disease. Both interventions showed hormetic effects—that is, beneficial at low levels, but detrimental at higher intensities or doses.

Does salinity make a difference—Kidney anatomy of Saimaa (Pusa saimensis) and Baltic ringed seals (Pusa hispida botnica)

open access: yesThe Anatomical Record, EarlyView.
Abstract As habitat salinity markedly differs between the endangered, freshwater‐dwelling Saimaa ringed seal (Pusa saimensis Nordquist, 1899) and the brackish water‐inhabiting Baltic ringed seal (Pusa hispida botnica Gmelin, 1788), we investigated whether this difference has resulted in morphological changes to their kidneys.
