Potential effects of traffic noise on anuran call characteristics in Louisiana, USA during winter.

Urban environments expose wildlife to levels of anthropogenic noise they would not experience in rural areas (e.g., traffic noise), and research suggests that many species adjust their acoustic signals for optimal transmission in urban soundscapes.

Leaves as bottlenecks: The contribution of tree leaves to hydraulic resistance within the soil-plant-atmosphere continuum.

Within vascular plants, the partitioning of hydraulic resistance along the soil-to-leaf continuum affects transpiration and its response to environmental conditions. In trees, the fractional contribution of leaf hydraulic resistance (R ) to total soil-to-leaf hydraulic resistance (R ), or fR (=R /R ), is thought to be large, but this has not been tested comprehensively. We compiled a multibiome data set of fR using new and previously published measurements of pressure differences within trees in situ.
