Heliyon, 2019 Stress may have negative or positive effects in dependence of its intensity (hormesis). We studied this phenomenon in Caenorhabditis elegans by applying weak or severe abiotic (cadmium, CdCl2) and/or biotic stress (different bacterial diets) during ...

Invasive‐plant traits, native‐plant traits, and their divergences as invasion factors
Ecology and EvolutionInvasive plants exert significant ecological impacts on native plants, communities, and ecosystems. However, consistent conclusions regarding how traits of invasive plants, native plants, and their divergences affect invasion dynamics are still lacking ...

Animal Research and One Health, EarlyView.Heat stress disrupts gut microbial balance in poultry, impairing nutrient absorption and immunity. This review outlines the interplay between thermal stress and microbiome dynamics and discusses integrative mitigation strategies, probiotics, phytogenics, cooling systems, and genetic adaptation to enhance poultry resilience.

Manipulation of Senescence of Plants to Improve Biotic Stress Resistance
Life, 2022 The physiological state, i.e., senescence or juvenility, of plants and plant organs can have strong effect on their reactions to pathogen attacks. This effect is mainly expressed as changes in the severity of disease symptoms. Generally, necrotrophic pathogens cause more severe symptoms on senescent than on juvenile plants, while biotrophs prefer ...

Modulation of Animal Gut Health by Milk Oligosaccharide
Animal Research and One Health, EarlyView.This review summarizes the composition and structural characteristics of MOs across different mammalian species, and elucidates their roles and mechanisms in maintaining intestinal homeostasis by regulating gut microbiome and enhancing intestinal chemical, physical and immune barriers.

Applied Plant Biotechnology for Improving Resistance to Biotic Stress
, 2020 Plants are continuing challenged by varied pathogens, including bacteria, fungi, viruses, and nematodes. Physical barriers such as polysaccharides are the first line of avoidance for pathogens entrance and cell invasion. To protect themselves against the invaders, plants have evolved innate immunity, through several mechanisms, receptor signalling ...

Acta HerpetologicaWe report the first documented case of interspecific ophiophagy by the naturalised false smooth snake (Macroprotodon mauritanicus), observed preying upon the introduced horseshoe whip snake (Hemorrhois hippocrepis) in Mallorca (Balearic Islands, Spain).

A roadmap to key traits of invasive Drosophilidae
Biological Reviews, EarlyView.ABSTRACT Biological invasions have intensified in recent decades, mostly driven by international trade and travel, raising significant concerns, particularly regarding insect pests. Once non‐native species establish, they can disrupt natural ecosystem stability, undermine agroecosystem sustainability and cause substantial economic losses.
