Russian wheat aphid: a model for genomic plasticity and a challenge to breeders

Insect Science, EarlyView.
Invasive foundress finds suitable habitat and reproduces through pathogenesis. Wingless females produce life offspring quickly, which leads to high population densities. High population densities result in competition, which may induce epigenetic changes and wing development for dispersal.

Pollen and phytoliths from fired ancient potsherds as potential indicators for deciphering past vegetation and climate in Turpan, Xinjiang, NW China. [PDF]

PLoS ONE, 2012
It is demonstrated that palynomorphs can occur in fired ancient potsherds when the firing temperature was under 350°C. Pollen and phytoliths recovered from incompletely fired and fully fired potsherds (ca.

Lithic analysis in African archaeology: Advances and key themes

Archaeometry, EarlyView.
Abstract Stone artifacts (lithics) preserve for extended periods; thus they are key evidence for probing the evolution of human technological behaviors. Africa boasts the oldest record of stone artifacts, spanning 3.3 Ma, rare instances of ethnographic stone tool‐making, and stone tool archives from diverse ecological settings, making it an anchor for ...

Oviposition Site Selection in Relation to Hatchling Feeding Performance in Two Sympatric Papilio Butterflies

Entomologia Experimentalis et Applicata, EarlyView.
We investigated oviposition site selection and hatchling feeding performance in two sympatric swallowtail butterflies, Papilio xuthus and Papilio memnon (Lepidoptera: Papilionidae), that utilize Citrus trees as host plants. Our study suggests that each species has unique relationships between maternal oviposition preferences and hatchling feeding ...
