Measuring, comparing and interpreting phenotypic selection on floral scent

2022

Natural selection on floral scent composition is a key element of the hypothesis that pollinators and other floral visitors drive scent evolution. The measure of such selection is complicated by the high-dimensional nature of floral scent data and uncertainty about the cognitive processes involved in scent-mediated communication. We use dimension reduction through reduced-rank regression to jointly estimate a scent composite trait under selection and the strength of selection acting on this trait. To assess and compare variation in selection on scent across species, time and space, we reanalyse 22 datasets on six species from four previous studies. The results agreed qualitatively with prev…

Prenatalny okres życia człowieka

2020

Rozwój człowieka w prenatalnym okresie życia interesował ludzi już w czasach starożytności. I choć do dziś prowadzi się wiele dyskusji na temat początku ludzkiego życia, należy stwierdzić, że rozwój poczętego dziecka oraz jego kompetencje wskazują na to, że od początku swojego istnienia jest to osoba aktywna i samosterowalna, która czuje, zapamiętuje, uczy się, posiada pewien poziom świadomości. Radzi sobie z trudnościami hamującymi jego rozwój, przystosowuje do zmiennych warunków życia nie tylko wewnątrz-, ale i zewnątrzmacicznego, nabywa pewnych nawyków i przyzwyczajeń, reaguje w indywidualny, charakterystyczny dla siebie sposób

Gaussian processes retrieval of crop traits in Google Earth Engine based on Sentinel-2 top-of-atmosphere data.

2022

The unprecedented availability of optical satellite data in cloud-based computing platforms, such as Google Earth Engine (GEE), opens new possibilities to develop crop trait retrieval models from the local to the planetary scale. Hybrid retrieval models are of interest to run in these platforms as they combine the advantages of physically-based radiative transfer models (RTM) with the flexibility of machine learning regression algorithms. Previous research with GEE primarily relied on processing bottom-of-atmosphere (BOA) reflectance data, which requires atmospheric correction. In the present study, we implemented hybrid models directly into GEE for processing Sentinel-2 (S2) Level-1C (L1C)…

Niche position drives interspecific variation in occupancy and abundance in a highly-connected lake system

2019

Highlights • We studied interspecific variation in occupancy and abundance of freshwater species. • Occupancy and abundance correlated positively for both diatoms and macroinvertebrates. • Niche position had clearest effects on variation in occupancy and abundance. • The more marginal the niche position, the rarer a species is. We examined how niche position, niche breadth, biological traits and taxonomic relatedness affect interspecific variation in occupancy and abundance of two commonly-used biological indicator groups, i.e. diatoms and macroinvertebrates. We studied 291 diatom and 103 macroinvertebrate species that occupied the littoral zones of a large (305 km2) highly-connected freshw…

Elämänarvot keski-iässä : psykometrinen rakenne ja yhteydet persoonallisuuden piirteisiin ja psyykkiseen hyvinvointiin

2016

This study examined, first, basic human values’ and life goals’ factor structures and the reciprocal links between these measures; second, the connections between personality traits and values, and possible gender differences in these relations; and third, the relations between life goals and mental well-being, and whether life goals act as mediators in the associations between personality traits and mental well-being. The participants were drawn from the Jyväskylä Longitudinal Study of Personality and Social Development (JYLS). Data used here were collected at ages 42 and 50 (n = 212–242). The results yielded a 14- factor value structure (societal concern, tolerance, protecting nature, car…

The role of temperament in children's affective and behavioral responses in achievement situations

2013

Abstract Although students' affects and behaviors in achievement situations have been shown to be influenced by their previous learning experiences, less is known about how they relate to students' dispositional characteristics, such as temperament. This study examined to what extent children's temperament is related to their affective and behavioral responses in achievement situations. Teachers rated first-graders' ( n  = 153) temperamental characteristics in the Fall semester. Children's active task avoidance, anxiety, and helplessness were rated in test situations in the Fall and Spring semesters. The results showed that the more easily distracted the children were, the more task avoidan…

ACTO II / ACT II Mujeres / Women ¿Es gay la música de Chopin? Aspectos de la recepción de la música de Chopin en el siglo XIX

2021

Considering that it is difficult, if not impossible, for an analysis of Chopin?s music to unmask some aspects of his private life (such as an alleged sexual and affective attraction for individuals of his own sex), we can however argue that, throughout the 19th century, a connection was established between his work and a ?feminine universe.? That connection might have had implications in the way in which the feminized image of its author was constructed. The analysis of certain aesthetic and stylistic traits of Chopin?s music can help understand the causes of that perception.
