Toxicity of Four Common Environmental Chemicals Across Caenorhabditis elegans Life Stages Supporting the One Health Concept

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Pesticides and pharmaceuticals are among the most common chemical groups in waterbodies and soils, and their universal distribution raises concerns about potential adverse effects on nontarget organisms and humans. Reproductive output disruption is of particular concern, as it transposes effects from the individual to the next generations at ...

Brood parasitism reduces but does not prevent Bombus terrestris reproductive success

open access: yesInsect Science, EarlyView.
Graphical depiction of the colony splitting process. Throughout figures in this paper, results pertaining to host success are represented in blue, and cuckoo success is represented in red. Abstract Cuckoo bumblebees are obligate brood parasites that must invade a colony of their host bumblebee species in order to reproduce.

Metabarcoding of Pollen Carried by Syrphids Reveals Novel Plant–Pollinator Interactions in a Protected Natural Area and Agricultural Sites

open access: yesEntomologia Experimentalis et Applicata, EarlyView.
Using DNA metabarcoding, this study investigates pollen transported by syrphids (Syrphidae) in the Dolomiti Bellunesi National Park and agricultural sites in Northern Italy. The analysis reveals a high diversity of visited plant taxa, including previously undocumented plant–pollinator interactions.

Effects of the neonicotinoid acetamiprid in syrup on Bombus impatiens (Hymenoptera: Apidae) microcolony development

open access: yesPLoS ONE, 2020
Worldwide, many pollinator populations are in decline. Population reductions have been documented for the agriculturally important honey bee (Apis mellifera), and other bee species such as bumble bees that are also critical for pollinating crops and ...

The First Report of Holothuria (Thymiosycia) impatiens (Forsskål, 1775), (Holothuroidea: Holothuriidae) from Tunisia (Mediterranean Sea): Taxonomic, Morphological, and Molecular Data Compilation

open access: yesDiversity, 2023
For the first time, specimens of Holothuria impatiens are reported from the Tunisian coast, supported by molecular (COI sequencing) and morphological (examination of ossicles) analyses.

The Modified Pharaoh Approach: Stingless bees mummify beetle parasites alive [PDF]

open access: yes, 2008
Social insect colonies usually live in nests, which are often invaded by parasitic species^1^. Workers from these colonies use different defence strategies to combat invaders^1^.

Two Metschnikowia nectar yeast species have similar volatile profiles but elicit differential foraging in bee pollinators

open access: yesEcological Entomology, EarlyView.
Yeasts that specialize in flower nectar play an important role in pollination ecology. Metschnikowia reukaufii and Metschnikowia koreensis were the most prevalent nectar yeasts found in our field sites. Bee pollinators exhibited different behavioural responses to nectar yeasts in field experiments. Bees visited more flowers with M.

Effects of Exogenous Salicylic Acid on Drought Response and Characterization of Dehydrins in Impatiens walleriana

open access: yesPlants, 2020
Impatiens walleriana is a valued ornamental plant sensitive to drought stress. We investigated whether the foliar application of 2mM salicylic acid (SA) can protect potted I. walleriana plants from drought stress.

Contrasting strategies in morphological and physiological response to drought stress among temperate forest understory forbs and graminoids

open access: yesPlant Biology, EarlyView.
Under drought stress, temperate forest understorey forbs prioritize biomass and leaf area retention, while graminoids enhance water‐use efficiency and photoprotection for survival. Abstract Drought stress can profoundly affect plant growth and physiological vitality, yet there is a notable scarcity of controlled drought experiments focused on ...
