Detecting coherent signals of climate change is best achieved by conducting expansive, long‐term studies. Here, using counts of waders ( Charadrii ) collected from ca. 3500 sites over 30 years and covering a major portion of western Europe, we present the largest‐scale study to show that faunal abundance is influenced by climate in winter. We demonstrate that the ‘weighted centroids’ of populations of seven species of wader oc...

Summary The prokaryotic enhancer‐binding protein XylR is the central regulator of the toluene degradation pathway in Pseudomonas species. Copious genetic and biochemical data indicate that the N‐terminal domain of the protein (domain A) interacts directly with m‐ xylene, which renders the protein competent as a transcriptional activator. Single‐site and shuffling mutants of XylR or homologues have been reported to change or ex...
