Data from: The phenotypic correlates and quantitative genetics of masculinization in the rodent, Octodon degus

Derek A. Roff, Matthew E. Wolak, Loreto A. Correa & Mauricio Soto-Gamboa
In some mammals female characteristics have been shown to depend in part on the intrauterine position during development of female fetuses relative to male fetuses. Females developing in close proximity to males show behavioural, physiological and life history characteristics that are masculinized. With the exception of one inconclusive study, nothing is known of the genetic basis of this phenomenon. In this paper we reported an analysis of the quantitative genetic basis of masculinization, as indicated...

Data from: Kelp and dolphin gulls cause perineal wounds in South American fur seal pups (Arctocephalus australis) at Guafo Island, Chilean Patagonia

Mauricio Seguel, Francisco Muñoz, Felipe Montalva, Diego Perez-Venegas, Héctor Paves & Nicole Gottdenker
During five reproductive seasons, we documented the presence, extent and origin of perineal wounds in South American fur seal pups (Arctocephalus australis) on Guafo Island, Northern Chilean Patagonia. The seasonal prevalence of perineal wounds ranged from 5 to 9%, and new cases were more common at the end of the breeding season (February), when pups were on average two months old and were actively expelling hookworms (Uncinaria sp). Histologically, wounds corresponded to marked ulcerative lymphoplasmacytic...

Data from: Diet reveals links between morphology and foraging in a cryptic temperate reef fish

Natalia S. Winkler, Maite Paz-Goicoechea, Robert W. Lamb & Alejandro Pérez-Matus
Predators select prey so as to maximize energy and minimize manipulation time. In order to reduce prey detection and handling time, individuals must actively select their foraging space (microhabitat) and populations exhibit morphologies that are best suited for capturing locally available prey. We explored how variation in diet correlates with habitat type, and how these factors influence key morphological structures (mouth gape, eye diameter, fin length, fin area, and pectoral fin ratio) in a common...

Data from: The positive side of a negative reference: the delay between linguistic processing and common ground

Edmundo Kronmüller, Ira Noveck, Natalia Rivera, Francisco Jaume-Guazzini & Dale Barr
Interlocutors converge on names to refer to entities. For example, a speaker might refer to a novel looking object as the jellyfish and, once identified, the listener will too. The hypothesized mechanism behind such referential precedents is a subject of debate. The common ground view claims that listeners register the object as well as the identity of the speaker who coined the label. The linguistic view claims that, once established, precedents are treated by listeners...

Data from: Early life experience drives short-term acclimation of metabolic and osmoregulatory traits in the leaf-eared mouse

Grisel Cavieres, Monica Nuñez-Villegas, Francisco Bozinovic & Pablo Sabat
We studied the putative effect of early experience on the physiological flexibility of metabolic and osmoregulatory traits in the leaf-eared mouse Phyllotis darwini, an altricial rodent inhabiting seasonal mediterranean environments. Adult individuals were collected in central Chile and maintained in breeding pairs. Pups were isolated after weaning and acclimated to different temperature (cold or warm) and water availability (unrestricted and restricted) until adulthood. Subsequently, individuals were re-acclimated to the opposite treatment. Rodents reared in warm...
