Structural stability of plant–pollinator interactions despite seasonal abundance of long‐tongued hawkmoths

Oikos, EarlyView.
Seasonal environmental cycles affect plant–pollinator interactions by altering plant phenology. Periods of low resource availability can filter pollinators and reduce the complexity of interaction networks, but the extent to which the functional morphology of pollinators influences such filtering remains unclear.

A Systematic Nomenclature for the Drosophila Ventral Nervous System [PDF]

, 2017
Insect nervous systems are proven and powerful model systems for neuroscience research with wide relevance in biology and medicine. However, descriptions of insect brains have suffered from a lack of a complete and uniform nomenclature.

Omics Insights Into the Effects of Highbush Blueberry and Cranberry Crop Agroecosystems on Honey Bee Health and Physiology

PROTEOMICS, EarlyView.
ABSTRACT Honey bees (Apis mellifera) are vital pollinators in fruit‐producing agroecosystems like highbush blueberry (HBB) and cranberry (CRA). However, their health is threatened by multiple interacting stressors, including pesticides, pathogens, and nutritional changes.

Development of a Grasshopper‐Leg‐Inspired Back‐Type Exoskeleton for the Reduction of Muscle Activation During Stoop Activities

Journal of Field Robotics, EarlyView.
ABSTRACT Farmers frequently suffer from musculoskeletal disorders, particularly lower back pain (LBP), mainly due to occupational ergonomic factors such as repetitive stooping and lifting. This study proposes using an exoskeleton to reduce LBP risk by providing external torque to the hip joints.

Energetics of pupal-adult metamorphosis in the silkworm, Bombyx mori : An analysis of transdeamination parameters in the fat body and haemolymph [PDF]

, 2018
Transdeamination seems to be an important alternative energy-intensive gluconeogenesis mechanism that generates glucose from non-carbohydrate sources during pupal-adult metamorphosis in Bombyx mori. Studies on four transdeamination parameters, viz., free

Evolution of thorax architecture in ant castes highlights trade-off between flight and ground behaviors [PDF]

, 2014
The concerted evolution of morphological and behavioral specializations has compelling examples in ant castes. Unique to ants is a marked divergence between winged queens and wingless workers, but morphological specializations for behaviors on the ground

First Assessment of Genetic Damage in the Speckled Cockroach (Nauphoeta cinerea) After Consumption of Lettuce (Lactuca sativa) Cultivated and Commercialized in Northeastern, Brazil

Environmental Toxicology, EarlyView.
ABSTRACT This study reports, for the first time, the use of the speckled cockroach Nauphoeta cinerea as a promising bioindicator for genotoxic monitoring. It was validated through control groups (both positive and negative) in addition to testing lettuce (Lactuca sativa ) samples from public street markets consumed by N. cinerea specimens in Pernambuco,
