Data from: Acoustic adaptation to city noise through vocal learning by a songbird

Dana Lynn Moseley, Graham Earnest Derryberry, Jennifer Nicole Phillips, Julie Elizabeth Danner, Raymond Michael Danner, David Andrew Luther & Elizabeth Perrault Derryberry
Anthropogenic noise imposes novel selection pressures, especially on species that communicate acoustically. Many animals – including insects, frogs, whales, and birds – produce sounds at higher frequencies in areas with low-frequency noise pollution. Although there is support for animals changing their vocalizations in real time in response to noise (i.e., immediate flexibility), other evolutionary mechanisms for animals that learn their vocalizations remain largely unexplored. We hypothesize that cultural selection for signal structures less masked by...

Data from: Suffering in receivers: negative effects of noise persist regardless of experience in female anurans

Masayuki Senzaki, Taku Kadoya, Clinton D. Francis, Nobuo Ishiyama & Futoshi Nakamura
1. Anthropogenic noise is widespread, and growing evidence suggests that it can negatively affect animals through many different mechanisms including masking of cues and signals, distraction, and aversion to noise. 2. Acoustic masking has received the most attention from researchers and recent evidence suggests that masking effects can be mitigated by alteration of signal frequencies or amplitudes by signalers. Additionally, alteration can be a learned response via prior experience with noise exposure. However, it remains...

Data from: The effect of range overlap on ecological niche divergence depends on spatial scale in monkeyflowers

Qin Li, Dena L. Grossenbacher & Amy L. Angert
Patterns of niche divergence and geographical range overlap of closely related species provide insights into the evolutionary dynamics of ecological niches. When ranges overlap, shared selective pressures may preserve niche similarity along coarse‐scale macrohabitat axes (e.g., bioclimates). Alternatively, competitive interactions may drive greater divergence along local‐scale microhabitat axes (e.g., micro‐topographical features). We tested these hypotheses in 16 species pairs of western North American monkeyflowers (Erythranthe and Diplacus, formerly Mimulus) with species’ niches, geographic ranges and...

Data from: Sympatric serpentine endemic Monardella (Lamiaceae) species maintain habitat differences despite hybridization

Kathleen M. Kay, Suzie Woolhouse, Brett A. Smith, Nathaniel S. Pope & Nishanta Rajakaruna
Ecological differentiation and genetic isolation are thought to be critical in facilitating coexistence between related species, but the relative importance of these phenomena, and the interactions between them, are not well understood. Here we examine divergence in abiotic habitat affinity and the extent of hybridization and introgression between two rare species of Monardella (Lamiaceae) that are both restricted to the same serpentine soil exposure in California. Although broadly sympatric, they are found in microhabitats that...
