Non-Canonical, Somatic-Dependent Vertical Transmission of Wolbachia in an Aphid. [PDF]
Environ Microbiol RepWe discovered a novel somatic‐associated Wolbachia transmission strategy in cedar bark aphids (Cinara cedri), contrasting with its typical maternal vertical transmission. This unique maternally retained somatic re‐acquisition strategy—a “piggybacking” on the highly efficient obligate symbiont transmission pathway—reveals diverse endosymbiont strategies

Water availability shapes temporal patterns of extrafloral nectar secretion and ant visitation to a Neotropical legume. [PDF]
Plant Biol (Stuttg)Drought duration affects ant–plant interactions: extrafloral nectar quality initially increases and subsequently declines, and ant interaction patterns closely track these nectar dynamics. Abstract Mutualistic plants use non‐structural sugar (NSC) to produce carbon‐based resources to reward partners.

Spiroplasma Display an Intricate Continuum of Infection Heterogeneity and Persistence in Myrmica Ants. [PDF]
Mol EcolABSTRACT Many bacterial taxa evolved facultative symbiotic associations with insects and spread through host populations by horizontal and maternal transmission. Co‐infection at the individual host level may facilitate or constrain the spread of facultative symbionts.

A Non-Parametric Approach for Identification of Parameter Varying Hammerstein Systems
IEEE Access, 2022 This paper presents a novel method for non-parametric identification of parameter-varying (PV) Hammerstein systems where the parameters of both the static nonlinearity and the linear dynamics change with a scheduling variable.
