Analysing the Ecological Requirements of the Australian Tortoise Beetle Trachymela sloanei (Blackburn, 1897) (Coleoptera: Chrysomelidae) to Determine the Prospects for Its Invasion Process

Journal of Applied Entomology, EarlyView.
ABSTRACT Invasive species pose a serious threat to biodiversity and result in significant economic costs. Although much effort is devoted to understanding invasive processes, some aspects are poorly understood, such as the early stages of invasions and the reasons for invasion failure.

Pollinator efficiency, rather than bee decline, explains a shift to hummingbird pollination in tropical montane forests

New Phytologist, EarlyView.
Hummingbird pollination is a hallmark of American plant diversity and has long been thought to evolve in tropical mountains due to declining bee activity. Using sister species of Costus specialized on bees (C. kuntzei) and hummingbirds (C. wilsonii), we show that this shift is not driven by reduced bee visitation with elevation, but by greater ...

Locally adapted Arabidopsis thaliana accessions show transcriptomic plasticity in a multi‐timescale analysis of whole‐genome gene expression in a natural environment

Plant Biology, EarlyView.
Natural Arabidopsis thaliana accessions showed remarkable plasticity in both life‐cycle phenology and whole‐genome gene expression patterns in in natura field experiments. Nevertheless, local adaptation in fitness‐related life‐history traits can also be detected at the whole‐genome gene expression level.
