Published in 2019 at "Journal of Arid Environments"

DOI: 10.1016/j.jaridenv.2018.12.002

Abstract: Abstract Ecological stoichiometry (ES) offers a framework to identify the mechanisms that allow pest species to thrive following human-induced rapid environmental change (HIREC). Specifically, ES links the biochemical composition of an organism to their growth… read more here.

Published in 2019 at "Behavioral Ecology"

DOI: 10.1093/beheco/arz153

Abstract: Population-level trait variation within species plays an often-overlooked role in interspecific interactions. In this study, we compared among-individual variation in web phenotype and foraging behavior between native black widows (Latrodectus hesperus) and invasive brown widows… read more here.

Published in 2023 at "Environmental Entomology"

DOI: 10.1093/ee/nvad003

Abstract: Abstract Female black widow spiders, Latrodectus hesperus Chamberlin and Ivie (Araneae: Theridiidae), are solitary predators of arthropods with no tolerance for intruders on the webs. In California, L. hesperus are found in urban and agricultural… read more here.

Published in 2020 at "Monthly Notices of the Royal Astronomical Society"

DOI: 10.1093/mnras/staa2339

Abstract: The wealth of detections of millisecond pulsars (MSPs) in $\gamma$-rays by {\em Fermi} has spurred searches for these objects among the several unidentified $\gamma$-ray sources. Interesting targets are a sub-class of binary MSPs, dubbed "Black… read more here.

Published in 2018 at "Monthly Notices of the Royal Astronomical Society"

DOI: 10.1093/mnras/stx3319

Abstract: We study in this work the evolution of the magnetic field in ‘redback–black widow’ pulsars. Evolutionary calculations of these ‘spider’ systems suggest that first the accretion operates in the redback stage, and later the companion… read more here.

Published in 2019 at "Monthly Notices of the Royal Astronomical Society"

DOI: 10.1093/mnras/stz374

Abstract: In regions with strongly varying electron density, radio emission can be magnified significantly by plasma lensing. In the presence of magnetic fields, magnification in time and frequency will be different for two circular polarizations. We… read more here.

Published in 2022 at "Royal Society Open Science"

DOI: 10.1098/rsos.221012

Abstract: Lizards and spiders are natural adversaries, yet little is known of adaptations that lizards might possess for dealing with the venomous defences of spider prey. In the Western USA, two lizard species (Elgaria multicarinata and… read more here.

Published in 2020 at "IEEE Access"

DOI: 10.1109/access.2020.3037510

Abstract: This article presents a novel method for identification of synchronous generator parameters that is based on sudden short-circuit test data and a novel metaheuristic algorithm, called the adaptive black widow optimization algorithm. Unlike traditional methods… read more here.

Published in 2020 at "PLoS ONE"

DOI: 10.1371/journal.pone.0228988

Abstract: Males of widow spiders courting on the web of females engage in web-reduction behavior which entails excising a section of the web, bundling it up, and wrapping it with their silk. Males of the false… read more here.

Published in 2022 at "PLoS ONE"

DOI: 10.1371/journal.pone.0267398

Abstract: The steroid hormone 20-hydroxyecdysone (20E) controls molting in arthropods. The timing of 20E production, and subsequent developmental transitions, is influenced by a variety of environmental factors including nutrition, photoperiod, and temperature, which is particularly relevant… read more here.

Published in 2023 at "Algorithms"

DOI: 10.3390/a16050225

Abstract: The problem regarding the optimal placement and sizing of different FACTS (flexible alternating current transmission systems) in electrical distribution networks is addressed in this research by applying a master–slave optimization approach. The FACTS analyzed correspond… read more here.
