Article
Full-text available
Animal personality may affect an animal’s mobility in a given landscape, influencing its propensity to take risks in an unknown environment. We investigated the mobility of translocated common voles in two corridor systems 60 m in length and differing in width (1 m and 3 m). Voles were behaviorally phenotyped in repeated open field and barrier test...

Data
Electronic supplementary material, figure S1. Results of the Structure [38] analysis showing average log-likelihood value values based on five replicates for each value of K, the hypothesized number of clusters in the data. Electronic supplementary material, table S1. Numbers of sea lion tissue samples collected and successfully sequenced for the m...
Article
Full-text available
Understanding the causes of population decline is crucial for conservation management. We therefore used genetic analysis both to provide baseline data on population structure and to evaluate hypotheses for the catastrophic decline of the South American sea lion (Otaria flavescens) at the Falkland Islands (Malvinas) in the South Atlantic. We genoty...
Data
Uncertainty plots derived from the model-based clustering of southern sea lion pup stable isotopes, implemented within the R Package ‘Mclust’. The ellipses shown represent each cluster, with the smallest grey dots representing the lowest uncertainty and large black dots, the largest uncertainty (quantiles are 0.75,0.95 –the default quantiles used i...
Data
Isotope data for 65 southern sea lion pups sampled from breeding colonies around the Falkland Islands (see ‘Methods’ for details). (DOCX)

Individuals within populations often differ substantially in habitat use, the ecological consequences of which can be far reaching. Stable isotope analysis provides a convenient and often cost effective means of indirectly assessing the habitat use of individuals that can yield valuable insights into the spatiotemporal distribution of foraging spec...
Article
Full-text available
Background: Prenatal conditions influence offspring development in many species. In mammals, the effects of social density have traditionally been considered a detrimental form of maternal stress. Now their potential adaptive significance is receiving greater attention.Sex-specific effects of maternal social instability on offspring in guinea pigs...
Conference Paper
In vision, the perceived velocity of a moving stimulus is different depending on whether the image moves across the retina with the eyes immobile or whether the observer pursues the stimulus such that the stimulus is stationary on the moving retina. The effect is known as the Aubert-Fleischl phenomenon. Here, we reproduced the analog of this visual...
Article
Full-text available
The prenatal social environment affects offspring development in most studied taxa with potentially lifelong consequences. To understand the adaptive significance of such maternal influences on offspring development, it is important to study their effects on fitness. In guinea pigs, social instability during pregnancy leads to delayed development o...
Conference Paper
Full-text available
Prenatal environment influences early development in many species, shaping their morphology, physiology or behavior. In mammals, research has focused on the negative effects of high social density during the mother's pregnancy on offspring phenotype. Guinea pigs have a long pregnancy and are highly precocial, resulting in a large scope for prenatal...

Question
Can somebody tell me or suggest a good paper?
So far I found many papers commenting just about the strenght/weakness of this test, or further information about the sign test. But I would like to use the results of this test as well and unfortunatly I can't find a good explanaition, how to understand this value.
Thank you!
Question
Version 3.5.1.3 - I am trying to find the right commands, but I cant find them on the manual. Does anybody know a step be step explanation?
Thank you!

Project
BioMove RTG links innovative individual research projects that overcome the gap between movement ecology and biodiversity research, employing a joint conceptual framework. We investigate how ongoing changes in climate and land use, such as habitat loss and fragmentation through agricultural practises, influence movement processes of various organisms and thereby biodiversity patterns. www.biomove.org
