Side effects of pesticides used in organic and conventional tomato crops on Dolichogenidea gelechiidivoris, a parasitoid of Tuta absoluta

open access: yesPest Management Science, EarlyView.
This study reveals strong variability in the effects of eight tomato integrated pest management‐compatible pesticides on Dolichogenidea gelechiidivoris, identifying harmful compounds such as spinosad and more selective ones such as sulfur and spiromesifen, depending on the exposure route.

Detecting Invasive Insects with Unmanned Aerial Vehicles [PDF]

open access: yes, 2019
A key aspect to controlling and reducing the effects invasive insect species have on agriculture is to obtain knowledge about the migration patterns of these species. Current state-of-the-art methods of studying these migration patterns involve a mark-release-recapture technique, in which insects are released after being marked and researchers attempt ...

Seeking Common Ground While Reserving Differences: Multiple Anatomy Collaborative Framework for Undersampled MRI Reconstruction [PDF]

open access: yesarXiv, 2022
Recently, deep neural networks have greatly advanced undersampled Magnetic Resonance Image (MRI) reconstruction, wherein most studies follow the one-anatomy-one-network fashion, i.e., each expert network is trained and evaluated for a specific anatomy.

Nature's Autonomous Oscillators [PDF]

open access: yes, 2012
Nonlinearity is required to produce autonomous oscillations without external time dependent source, and an example is the pendulum clock. The escapement mechanism of the clock imparts an impulse for each swing direction, which keeps the pendulum ...

High concentrations of fluorescent nanoprobes delayed Oryzias melastigma embryo hatching by modulating respiratory and metabolic pathways

open access: yesVIEW, EarlyView.
We investigated the developmental toxicity of a new graphene‐based fluorescent nanoprobe for tumor cell nucleus (GTTNs) using Oryzias melastigma embryos. The results confirmed that GTTNs have excellent biocompatibility for biomedical applications. Only the highest dose delayed hatching time.

Dietary adaptations along the northern limit of distribution: what does the smooth snake Coronella austriaca eat in Norway? Metabarcoding of stomach content and visual analysis of faeces

open access: yesWildlife Biology, EarlyView.
Understanding how species survive at their poleward limits of distribution is of interest in species conservation, particularly in light of global warming and predictions of shifting distributions of both predators and prey species. How species adapt to high latitudes and to future climate changes will be impacted both by direct interactions with the ...

Tracking large bees in open landscapes with active radio tags—Advantages and challenges using stationary receivers

open access: yesJournal of Animal Ecology, EarlyView.
Studying the spatial ecology of ecologically relevant species supports the development of effective conservation strategies. Recent technological advancements in remote tracking methods now enable researchers to study large flower‐visiting insects and important pollinators, such as carpenter bees.
