Drought stress triggers differential survival and functional trait responses in the establishment of Arnica montana seedlings
(2021-07-15)
- The establishment and survival of seedlings are critical stages in the life cycle of plants and therefore usually well timed to humid and favourable conditions. Climate projections suggest that the threatened mountain grassland species Arnica montana may be increasingly exposed to drought stress. However, studies that focus on the species’ early development are missing. We evaluated impacts of drought-induced stress on A. montana seedlings in their early establishment phase and identified traits that could cause ...

Indicators of Affect Dynamics: Structure, Reliability, and Personality Correlates
(2020-07-21)
Researchers are increasingly interested in the affect dynamics of individuals for describing and explaining personality and psychopathology. Recently, the incremental validity of more complex indicators of affect dynamics (IADs; e.g. autoregression) has been called into question (Dejonckheere et al., 2019), with evidence accumulating that these might convey little unique information beyond mean level and general variability of emotions. Our study extends the evidence for the construct validity of IADs by investigating ...

Morphologically similar but not closely related: the long-sporedspecies of Subulicystidium (Trechisporales, Basidiomycota)
(2020-06-06)
Species boundaries and geographic distribution of corticioid fungi (resupinate Basidiomycota) are often poorly known. Ourrecent study onSubulicystidiumshowed that species diversity in this genus is at least twice as high as previously recognized. Thisre-estimation of the species diversity was based on a study of only a part of the genus. The present study sheds light on molecularand morphological diversity of three more species. We generated 27 ITS and 24 28S nuclear ribosomal DNA sequences from 49specimens labelled ...

Iterative feature detection of a coded checkerboard target for the geometric calibration of infrared cameras
(2021-08-11)
The geometric calibration of cameras becomes necessary when images should be undistorted, geometric image information is needed or data from more than one camera have to be fused. This process is often done using a target with a checkerboard or circular pattern and a given geometry. In this work, a coded checkerboard target for thermal imaging cameras and the corresponding image processing algorithm for iterative feature detection are presented. It is shown that, due in particular to the resulting better feature ...

Animal Welfare Consequences of Organic Boar Fattening and Occurrence of Boar Taint on Five Commercial Farms
(2021-10-10)
Simple Summary
The usual castration of male fattening pigs is under discussion, especially in organic farming, because of the negative effects on the pig’s welfare and integrity. Nevertheless, it is feared that boars show more aggressive and mounting behaviours, resulting in stress, painful injuries and lameness, and that their meat has an unpleasant odour/taste (called “boar taint”). Therefore, it was examined to which extent these concerns come true under commercial organic conditions. Additionally, influences ...

Psychosocial Interventions for Newly Arrived Adolescent Refugees: A Systematic Review
(2020-02-25)
Adolescent refugees are confronted with multiple developmental, psychological, and social challenges after flight. Psychosocial interventions are therefore necessary to support adolescents during the first period after arrival in a receiving country and to avoid negative long-term consequences. Unfortunately, little is known about the types and the effects of such interventions provided during this time. This systematic review aimed to synthesize research about psychosocial interventions for refugee youth during the ...

Using CFD Modelling to Relate Pig Lying Locations to Environmental Variability in Finishing Pens
(2020-03-03)
The purpose of this research was to determine which environmental factors within the pen space differ between the locations where pigs choose to lie and areas they avoid. Data on external weather engconditions and the construction parameters for an existing commercial finishing pig building were input into a Dynamic Thermal (DT) model generating heat flow and surface temperature patterns in the structure and these were then input into a Computational Fluid Dynamics (CFD) model to generate data on the theoretical ...

Best, Heinrich/Higley, John (Hrsg.): The Palgrave Handbook of Political Elites, 698 S., Palgrave Macmillan, London 2018.
(2020-01-16)
Heinrich Best (Friedrich-Schiller-Universität Jena) und John Higley (University of Connecticut) haben mit dem knapp 700 Seiten umfassenden Handbuch eine bemerkenswerte Bestandsaufnahme der Forschung zu politischen Eliten vorgelegt. Beide Herausgeber haben sich über mehrere Jahrzehnte hinweg mit diesem Thema beschäftigt. Politische Eliten sind dabei nicht in einem engen Sinne ausschließlich als politische Entscheidungsträger zu verstehen, sondern werden weiter definiert als alle Personen, die Einfluss auf politische ...

Mismatch of Glucose Allocation between Different Life Functions in the Transition Period of Dairy Cows
(2020-06-13)
Simple Summary
The reasons for the development of diseases in the transition period of dairy cows are manifold and highly farm- and cow-specific. Nevertheless, links exist between the degree of negative energy balance (NEB) and disease susceptibility, which suggest a mutual adverse relationship between immune and productive functions. Glucose is the most essential fuel and precursor for both immune cells and mammary epithelial cells (MEC). While the delivery of glucose by the intermediary metabolism is not always ...

The Potential Influence of Organic Food Consumption and Intention-Behavior Gap on Consumers’ Subjective Wellbeing
(2020-05-18)
This paper applied a self-administered survey to investigate the impact of organic food behavior and the intention-behavior gap in organic food consumption (OIBG) on consumers’ subjective wellbeing including physical, emotional, social and intellectual dimensions. The survey was carried out with 385 consumers. Furthermore, the study conducted a food test to explore the different impacts of organic and conventional food samples on the mental and physical conditions of consumers’ wellbeing applying a psychological ...
