Consistent phenological shifts in the making of a biodiversity hotspot: the Cape flora
2011
Abstract Background The best documented survival responses of organisms to past climate change on short (glacial-interglacial) timescales are distributional shifts. Despite ample evidence on such timescales for local adaptations of populations at specific sites, the long-term impacts of such changes on evolutionary significant units in response to past climatic change have been little documented. Here we use phylogenies to reconstruct changes in distribution and flowering ecology of the Cape flora - South Africa's biodiversity hotspot - through a period of past (Neogene and Quaternary) changes in the seasonality of rainfall over a timescale of several million years. Results Forty-three dist…
Co‐occurrence patterns in a steppe bird community: insights into the role of dominance and competition
2023
Spatial co-occurrence patterns are determined by environmental factors, such as food availability or habitat characteristics and by biotic associations. When resources are limited, competition which implies a dominant hierarchy can shape species assemblage. Here, we study space and time co-occurrence of steppe passerines during the breeding season in a natural steppe habitat, its modulation by environmental filtering, potential biotic interactions and random processes. We applied the joint species distribution model of hierarchical modelling of species community (HMSC) to data on species presence–absence and environmental, temporal and spatial covariates acquired from seven plots in a natur…
Evolutionary genomics can improve prediction of species' responses to climate change
2020
Abstract Global climate change (GCC) increasingly threatens biodiversity through the loss of species, and the transformation of entire ecosystems. Many species are challenged by the pace of GCC because they might not be able to respond fast enough to changing biotic and abiotic conditions. Species can respond either by shifting their range, or by persisting in their local habitat. If populations persist, they can tolerate climatic changes through phenotypic plasticity, or genetically adapt to changing conditions depending on their genetic variability and census population size to allow for de novo mutations. Otherwise, populations will experience demographic collapses and species may go ext…
Children’s Voices on Bullying in Kindergarten
2016
Research suggests that bullying does occur in kindergarten. The extent of bullying in Norway and other Scandinavian countries is estimated to be about 12 %. The purpose of this study is to investigate children’s understanding and experiences of bullying. We use a qualitative approach and have conducted individual interviews and focus group interviews with a total of 31 children, 5 year-olds, in 4 different kindergartens. Additionally, observations were made of 4–5 year-olds in the same kindergartens, 142 children in total. The results show that the children describe bullying as doing or saying “something mean”. Exclusion from play is what all the children fear the most. This study shows tha…
The link between violence and suicidal behavior among female university students in Spain
2019
Objective: To explore the association between violence and suicidal behavior in female university students. Method: A convenience sample of 540 female students enrolled in the Nursing and Teacher Training Faculties at the University of Valencia was selected. Violence by partners, nonpartners, and both was compared with suicidal thoughts and suicide attempts. An adjusted logistic regression and the Wald Test were performed to explore whether the effect on student's suicidal behavior differed if a partner or others committed violence. Results: 18.1% reported suicidal thoughts in the last month and 2.4% had attempted suicide in the past five years. Suicidal behavior was significantly higher in…

Psychological adjustment and victim-blaming among intimate partner violence offenders: The role of social support and stressful life events
2013
AbstractIntimate partner violence offenders often use victim-blaming attributions to explain their own violent behavior. These attributions represent an important challenge for intervention programs for intimatepartner violence offenders. The main objectives of this study were to analyze both the influence of social support and stressful life events on the psychological adjustment (self-esteem and depressive symptomatology) of intimate partner violence offenders and the relationship between offenders’ psychological adjustment and their victim-blaming attributions. The sample consists of 314 men convicted of intimate partner violence who were referred to a community-based intervention progra…
Kształcenie uczniów na rzecz zrównoważonego rozwoju w szkołach ponadgimnazjalnych o profilu technicznym
2017
W artykule podjęto próbę oceny dwupłaszczyznowego postrzegania problemu kształcenia uczniów dla zrównoważonego rozwoju realizowanego zgodnie z koncepcją społecznej odpowiedzialności biznesu (CSR) w środowisku lokalnym oraz analizę ich zachowań proekologicznych na przykładzie wybranych szkół ponadgimnazjalnych o profilu technicznym województwa opolskiego. Diagnoza i analiza badań przeprowadzona została w odniesieniu do komponentu poznawczego, afektywnego i behawioralnego postaw uczniów.
Ba/Ca ratios in shells of Arctica islandica —Potential environmental proxy and crossdating tool
2017
Abstract Ba/Ca shell time-series of marine bivalves typically show flat background levels which are interrupted by erratic sharp peaks. Evidence from the literature indicates that background Ba/Ca shell ratios broadly reflect salinity conditions. However, the causes for the Ba/Ca shell peaks are still controversial and widely debated although many researchers link these changes to primary productivity, freshwater input or spawning events. The most striking feature is that the Ba/Ca shell peaks are highly synchronous in contemporaneous specimens from the same population. For the first time, we studied Ba/Ca shell in mature and ontogenetically old (up to 251 year-old) specimens of the long-li…
