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.

Modified Grasshopper Algorithm-Based Multilevel Thresholding for Color Image Segmentation

IEEE Access, 2019
Multilevel thresholding is an important approach for image segmentation which has drawn much attention during the past few years. The Tsallis entropy method is implemented for its effectiveness and simplicity.

Summarization of Films and Documentaries Based on Subtitles and Scripts [PDF]

, 2016
We assess the performance of generic text summarization algorithms applied to films and documentaries, using the well-known behavior of summarization of news articles as reference. We use three datasets: (i) news articles, (ii) film scripts and subtitles,

Hemipteran vectors of stylet‐borne plant viruses: Aphids lead the charge

Insect Science, EarlyView.
Among all sap‐feeding hemipterans, aphids stand out by far as the most important vectors of noncirculative plant viruses. Compared to whiteflies and mealybugs, aphids’ highly specialized stylet anatomy and distinct feeding behaviors contribute, together with other features of their biology, to their remarkable efficiency in transmitting stylet‐borne ...

Acceptability of Grasshopper Nugget Flour as a High-Protein Functional Food

Health Dynamics
Background: Nugget products enhanced with locust flour are being explored as a novel source of functional food due to their high protein content, which plays a vital role in maintaining human health. Locusts, commonly consumed in parts of Africa and Asia,

The origins of postmating reproductive isolation: testing hypotheses in the grasshopper Chorthippus parallelus [PDF]

, 2002
Although there are several well-established hypotheses for the origins of postmating isolation during allopatric divergence, there have been very few attempts, to determine their relative importance in nature.

Beyond Sexual Selection: Natural Selection Related Camouflage and Thermoregulation Shape Sexual Color Dimorphism in Diploderma Lizards

Integrative Zoology, EarlyView.
Integrating comparative spectrometry, image analysis, and thermal modeling, we reveal that (1) females optimize crypsis via background matching, (2) males prioritize high‐contrast disruptive patterning at a significant thermoregulatory cost (reduced solar heat gain), and (3) habitat‐specific monomorphism in Diploderma slowinskii underscores ecological ...

ViBe (Virtual Berlin) - Immersive Interactive 3D Urban Data Visualization - Immersive interactive 3D urban data visualization [PDF]

, 2019
The project investigates the possibility of visualizing open source data in a 3D interactive virtual environment. We propose a new tool, 'ViBe'. We programmed 'ViBe' using Unity for its compatibility with HTC VIVE glasses for virtual reality (VR).

Mitochondrial Genomes Reveal Population Structure of the Locust Oedaleus decorus (Orthoptera: Acrididae: Oedipodinae) in China

Agronomy
The locust Oedaleus decorus undergoes massive outbreaks and engages in round-trip migratory flights across northern China and Mongolia. However, its specific genetic structure remains poorly understood.
