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.

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.

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.

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.

The invisible black widow PSR J1720-0534: implications for the electron density towards the North Polar Spur
Sign Up to like & getrecommendations! Published in 2024 at "Monthly Notices of the Royal Astronomical Society"
DOI: 10.1093/mnras/stae498
Abstract: Radio emission from pulsars can be used to map out their distances through dispersion measure (DM), which quantifies the amount of radio pulse dispersion. However, this method relies on accurately modeling the free electron density… read more here.

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.

Constraining magnetic fields through plasma lensing: application to the Black Widow pulsar
Sign Up to like & getrecommendations! 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.

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.
