Robotics for Crop Pollination: Recent Advances and Future Direction

Journal of Field Robotics, EarlyView.
ABSTRACT There is great interest in alternative pollination strategies for crop production in the face of climate change and perennial threats to the traditional pollination mechanisms. This review explores the potential of robotic pollination as a promising solution to these challenges affecting crop fertilization, agricultural sustainability, and ...

Taxonomic evaluation of three Egyptian Solanum species based on morphology, DNA sequences, and chromosome analysis

Caryologia
We investigated the intra-specific relationships between three Solanum species in Egypt: Solanum nigrum, Solanum villosum, and Solanum sinaicum, in addition to the inter-specific relationships among the populations of the three studied species.

Trace Levels of Triclosan May Affect Root Growth and Morphology in Cultivated Plants

Environmental Toxicology, EarlyView.
ABSTRACT Triclosan (TCS) is a micropollutant frequently detected in biosolids applied to agricultural soils. In soil solution—where it is potentially bioavailable to roots—it occurs at residual concentrations (ng L−1). Nevertheless, the ecotoxicological implications of TCS exposure in agricultural crops at these concentrations are still not fully ...

Plant‐derived nanovesicles as potential drug delivery systems for topical use: Emerging applications in dermatology and cosmetology

VIEW, EarlyView.
Plant‐derived nanovesicles (PDNVs) are naturally secreted by fruit, vegetables, seeds, leaves and other natural sources. Used as drug delivery systems, they can combine intrinsic therapeutic activity, enhanced skin permeation and cargo‐carrying capacity, suitable for dermatological and cosmetic applications including hydration, antioxidant/anti ...

A low‐cost, portable polarizing digital light microscope for monitoring crystal growth and for crystal harvesting

Journal of Applied Crystallography, EarlyView.
A low‐cost, portable, medium‐resolution polarizing digital light microscope device for monitoring crystal growth and for crystal harvesting is described. The device can be used with a cell phone or a personal computer for real‐time imaging by professional and amateur scientists alike.Motivated by the need for a convenient way to demonstrate the growth ...

Innate behaviours shape generalist herbivore host choice and feeding patterns independent of plant defences

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant–herbivore interactions are typically examined through plant defence and herbivore performance, yet individual herbivore behavioural mechanisms underlying these interactions are rarely considered alongside plant traits.

Iflaviruses in arthropods: when small is mighty

Insect Science, EarlyView.
Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

From the predator to the prey: a case study of the vulnerability of Harmonia axyridis to aggressive competitors

Insect Science, EarlyView.
The level of aggressiveness of an individual is a factor that shapes intraguild predation (IGP) interactions. In Nabis americoferus, high aggressiveness leads to an increase in attack rate and IGP against Harmonia axyridis. Moreover, the absence of extraguild prey seems to exacerbate IGP. In docile N.
