Data from: Evidence of weaker phenotypic plasticity by prey to novel cues from non-native predators

Johan Hollander & Paul E. Bourdeau
A central question in evolutionary biology is how coevolutionary history between predator and prey influences their interactions. Contemporary global change and range expansion of exotic organisms impose a great challenge for prey species, which are increasingly exposed to invading non-native predators, with which they share no evolutionary history. Here, we complete a comprehensive survey of empirical studies of coevolved and naive predator−prey interactions to assess whether a shared evolutionary history with predators influences the magnitude...

Data from: Sexual selection on male vocal fundamental frequency in humans and other anthropoids

Jablonski, Mark D. Shriver, Daniel J. Weiss, Adriano R. Lameira, Coren L. Apicella, Michael J. Owren, Claudia Barelli, Mary E. Glenn & Gabriel Ramos-Fernandez
In many primates, including humans, the vocalizations of males and females differ dramatically, with male vocalizations and vocal anatomy often seeming to exaggerate apparent body size. These traits may be favoured by sexual selection because low-frequency male vocalizations intimidate rivals and/or attract females, but this hypothesis has not been systematically tested across primates, nor is it clear why competitors and potential mates should attend to vocalization frequencies. Here we show across anthropoids that sexual dimorphism...

Data from: Seed predation has the potential to drive a rare plant to extinction

Helen M. Kurkjian, Sydney K. Carothers & Erik S. Jules
1. Pre-dispersal seed predation is sometimes considered unlikely to dramatically affect plant population growth because plants are generally expected to produce more seeds than there are safe sites for germination. Lupinus constancei is a rare herb of limited distribution, with fewer than 400 reproductive individuals restricted to a single square kilometre of north-western California, USA. In addition to the vulnerability resulting from its extremely small population size, L. constancei faces heavy seed predation by small...

Data from: Prescribed fire and conifer removal promote positive understorey vegetation responses in oak woodlands

Amy C. Livingston, J. Morgan Varner, Erik S. Jules, Jeffrey M. Kane & Leonel A. Arguello
Fire-prone woodlands and savannas world-wide face management challenges resulting from fire exclusion and subsequent encroachment of fire-sensitive trees. In the Pacific Northwest (USA), Quercus garryana oak woodlands and savannas are threatened by encroachment from the native conifer Pseudotsuga menziesii in the absence of fire. In the Bald Hills of Redwood National Park (California, USA), prescribed fire and conifer removal have been used to restore encroached woodlands. We examined the effects of encroachment and restoration on...

Data from: Novel concordance between geographic, environmental and genetic structure in the ecological generalist prickly sculpin (Cottus asper) in California

Jason Baumsteiger, Andrew P. Kinziger & Andres Aguilar
Ecological generalists may contain a wealth of information concerning diversity, ecology, and geographic connectivity throughout their range. We explored these ideas in prickly sculpin (Cottus asper), a small generalist freshwater fish species where coastal forms have potentially undergone radiations into inland lacustrine and riverine environments. Using a 962bp cytochrome b mtDNA marker and 11 microsatellites, we estimated diversity, divergence times, gene flow, and structure among populations at 43 locations throughout California. We then incorporated genetic...

Data from: Minimally invasive collection of adipose tissue facilitates the study of eco-physiology in small-bodied mammals

Jeff Clerc, Theodore J. Weller, Jeffrey B. Schineller & Joseph M. Szewczak
Adipose tissue is the primary fuel storage for vertebrates and is an important component of energy budgets during periods of peak energetic demands. Investigating the composition of adipose tissue can provide information about energetics, migration, reproduction and other life-history traits. Until now, most field methods for sampling adipose tissue of small-bodied vertebrates have been destructive. Therefore, investigations of adipose tissue in small-bodied vertebrates have been limited in their broadscale application. We developed a field-ready micro-adipose...
