Relevance of Broad-Leaved Forest Stands for Maintaining Epiphytic Bryophyte Species and Functional Trait Diversity in Forest Landscape in Latvia
2021
Abstract Broad-leaved trees play an important role in supporting epiphyte richness in deciduous forests. In this study we tested which broad-leaved forest stands in terms of tree composition best predicted biodiversity in regard to bryophyte species number and their functional traits. The bryoflora was surveyed in 70 stands differing in dominant broad-leaved tree species. One circular plot with diameter 30 meters was established in each stand situated in different parts of Latvia. Fifty-three of the plots were located in stands identified as protected habitats of the European Union. In total, 82 bryophyte species were recorded. At plot level the total number of species ranged between 6 and …
Effects of training and assessment in vocational education and training (VET): Reflections on the methodology of assessing the development of traits …
2006
Abstract This article focuses on the development of traits of self-regulation within vocational education and training (VET). This perspective is in accordance with the general objective of VET within the German speaking countries and is addressed in the objective “education and training for the ability of self-directed planning, regulation and evaluation of vocational performance”. In order to foster these and other relevant abilities, specific vocational training programs were developed and implemented in a training center in Switzerland. One such program was evaluated in a longitudinal study. From 1999 to 2003, a cohort of more than 100 aprentices was monitored with respect to the develo…
Adaption of the TSRQ for Financial Behavior
2013
The Trait Self Regulation Questionnaire (TSRQ) is an instrument to measure general self-regulative capabilities. In 1999, Klaus Breuer translated this instrument into a German version and adapted it to the field of self-regulation in educational processes within vocational training.
Genetic relationships, structure and parentage simulation among the olive tree (Olea europaea L. subsp. europaea) cultivated in Southern Italy reveal…
2013
In this work, we assess both the morphological and genetic diversity of 68 important olive cultivars from three Southern Italian regions: Calabria, Campania and Sicily. Twenty-five phenotypic traits were evaluated and 12 simple sequence repeat (SSR) markers were analysed. All SSR primers were polymorphic and reliable. The total number of alleles per locus varied from 5 to 19 with an average number of 13.1 and a mean polymorphic information content (PIC) of 0.81. These results suggested high genetic diversity within these three olive germplasm collections. Morphological traits also showed significant variability amongst cultivars. Two cases of identity were found and ten statistically signif…
Genetic diversity of early ripening breba accessions (Ficus caricaL.) found in the “Pomona” Apulian collection
2017
In order to study fig (Ficus carica L.) biodiversity in Southern Italy, a study was performed in a private Apulian collection, "I Giardini di Pomona", in which 350 different native and international cultivars were recovered in the last 15 years. This collection is located in middle part of Apulia region inside an area of great charm called "Valle D'Itria". In the region, fig is an important edible fruit tree species and it has been used for fresh fruit production, for centuries. Moreover, fig is considered as an important element of natural landscape and as significant cultural heritage. In this study, the Apulian breba cultivars, characterized by interesting agronomic traits, such as early…
Genetic variation of an Italian long shelf-life tomato (Solanum lycopersicon L.) collection by using SSR and morphological fruit traits
2014
The recovery of ancient germplasm in tomato (Solanum lycopersicon L.) has become necessary to limit the wide genetic erosion caused by the employment of modern cultivars. Among germplasm collections, long shelf-life landraces could represent an important source of biodiversity. The present study provides a first set of molecular and phenotypic data on long shelf-life (so called "da serbo" in southern Italy) tomato collection, mainly originated from Sicily together with some landraces from Campania and Apulia. The analysis of fruit traits showed a low intra-varietal variation, while exhibiting a quite higher inter-varietal variability. Overall, the cultivars have been classified in six fruit…
Gender, exercise, and health: A life-course cross-sectional study.
2020
The purpose of this study is to explore relationships between the practice of exercise, gender, and health, from adolescence to old age, testing the magnitude of gender differences throughout the life cycle in the practice of exercise of Spanish people. A cross-sectional study with 4,575 women and 4,334 men, aged 13-85 years, was conducted. The participants were assessed on the weekly hours they dedicated to the practice of exercise, masculine/instrumental and feminine/expressive traits, mental health symptomatology, and self-rated health). Univariate and multivariate analyses were performed in the age groups of adolescence, late adolescence, young adulthood, middle adulthood, and older age…
Obesity in Aging and Art
2009
THIS issue of Journal of Gerontology: Medical Sciences highlights new findings on obesity in older persons and its consequences for health and function (1,2,3). The obesity epidemic is spreading rapidly in both developed and developing countries, and perspectives on the negative effects of overweight and obesity abound in recent medical literature. What do we know so far about obesity over the lifetime? Obesity does not spare older persons (4). Obese older persons experience a wide range of negative consequences, including metabolic abnormalities, arthritis, pulmonary diseases, cataracts, cancer, impaired mobility, disability, and mortality. Given the already extensive knowledge base, why a…

Macrosystem community change in lake phytoplankton and its implications for diversity and function
2023
Aim We use lake phytoplankton community data to quantify the spatio-temporal and scale-dependent impacts of eutrophication, land-use and climate change on species niches and community assembly processes while accounting for species traits and phylogenetic constraints. Location Finland. Time period 1977–2017. Major taxa Phytoplankton. Methods We use hierarchical modelling of species communities (HMSC) to model metacommunity trajectories at 853 lakes over four decades of environmental change, including a hierarchical spatial structure to account for scale-dependent processes. Using a “region of common profile” approach, we evaluate compositional changes of species communities and trait profil…
