The specialised subterranean fauna is often described as an iconic example of convergent evolution driven by environmental constraints, representing therefore ideal model system for eco-evolutionary studies. During the colonization environments, behavioural plasticity likely plays a fundamental role, quick response individuals to new environment key process enabling their long-term establishmen...
Abstract Let $$\mathscr {X}$$ X be the set of positive real sequences $$x=(x_n)$$ x = ( n ) such that series $$\sum _n x_n$$ ? is divergent. For each $$x \in \mat...
Statistical reconstruction has become popular in emission computed tomography but suffers slow convergence (to the MAP or ML solution). Methods proposed to address this problem include the fast but non-convergent OSEM and the convergent RAMLA [1] for the ML case, and the convergent BSREM [2], relaxed OS-SPS and modified BSREM [3] for the MAP case. The convergent algorithms required a user-deter...
Despite contingency in life's history, the similarity of evolutionarily convergent traits may represent predictable solutions to common conditions. However, the extent to which overall gene expression levels (transcriptomes) underlying convergent traits are themselves convergent remains largely unexplored. Here, we show strong statistical support for convergent evolutionary origins and massivel...
