Assessing behavioural consistency is crucial to understand the evolution of personality traits. In the present study we examined the shortand long-term repeatability and stability of two unrelated personality traits—exploratory tendencies and struggling rate—using captive female zebra finches (Taeniopygia guttata). We performed two experimental sessions of(More)
Investigating patterns of among and within-individual trait variation in populations is essential to understanding how selection shapes phenotypes. Behavior is often the most flexible aspect of the phenotype, and to understand how it is affected by selection, we need to examine how consistent individuals are. However, it is not well understood whether(More)
Condition-dependence of male ornaments is thought to provide honest signals on which females can base their sexual choice for genetic quality. Recent studies show that condition-dependence patterns can vary within populations. Although long-term association is thought to promote honest signalling, no study has explored the influence of pairing context on(More)
The extended pace-of-life syndrome (POLS) hypothesis suggests that variation in boldness-like behaviors has co-evolved with variation in life-history strategies within populations, yet both theoretically driven experiments and evidence for phenotypic correlations between boldness-like behaviors and reproduction-related activities are scarce. Here we test(More)
Recent ecological and evolutionary research emphasizes the importance of adaptive trait integration. For instance, antipredator defenses are built up of several morphological and behavioral components in many species, yet their functional relationships are still poorly documented. Using field-collected freshwater crustaceans Gammarus fossarum in a(More)
Although increasing attention is given to both the causes and consequences of variation in animal personality, the measurement of personality in captive or free-ranging individuals remains an issue. In particular, one important question concerns whether personality should be established from the existence of complex behavioral syndromes (a suite of(More)

The purpose of this study is to compare success rate, patient satisfaction, discomfort, procedure time and intraoperative adverse events of hysteroscopic (Essure®) versus laparoscopic sterilisation. This study includes a retrospective case–control comparative study of 70 patients who had laparoscopic or hysteroscopic sterilisation performed. Systematic(More)
