Population trends of birds across the iron curtain: Brain matters
2011
One approach to assess human impact on species’ population dynamics is to correlate ecological traits of species with their long-term population trends. Yet, few studies investigated population trends in multiple regions that differ in human impact to reveal which traits explain population trends over larger geographic areas and which only regionally. We examined the relationship between various species traits and long-term population trends of 57 common passerine bird species from 1991 to 2007 in three adjacent regions in central Europe that experienced differences in socioeconomic history: North-Western Germany, Eastern Germany and the Czech Republic. We tested effects of habitat, dietary…
Breeding strategy and morphological characters in an urban population of blackbirds, Turdus merula
2001
Pairing patterns in monogamous birds are thought to be the consequence of mutual mate choice by males and females for characters linked to individual quality in the opposite sex. Although this may result in assortative pairing for a single character, there may be no simple match between male and female phenotype if the traits linked to individual quality are sex specific. For instance, in several passerine species, females tend to select males on the basis of territory quality or characters that may reflect health or vigour, whereas males benefit from pairing with females in good condition that breed early because early breeding increases reproductive success. We investigated pairing patter…
Within territory abundance of red wood ants Formica rufa is associated with the body condition of nestlings in the Eurasian treecreeper Certhia famil…
2007
Studies on individual reproductive success in relation to interspecific competition between distantly related taxa are scarce. We studied whether the abundance of red wood ants Formica rufa -group is related to the breeding habitat selection, fecundity and offspring quality in the Eurasian treecreeper Certhia familiaris, an old-growth forest passerine. The nest-box occupancy data were gathered over a five-year study period, whereas the breeding performance analyses were based on a two-year data set. The abundance of wood ants, measured within 50 m around the nest-boxes, was not related to nest-box occupancy rate, fecundity or the physiological stress of nestlings. In contrast, the abundance…
Combined strength and endurance exercise induced fatigue and recovery
2012
Muscular fatigue is usually defined as the inability to maintain a given exercise intensity or adequate muscle force and therefore maximal isometric force, neural activation and fast force production capacity have often used determinants of acute fatigue. The purpose of the present study was to measure the acute effects of combined strength and endurance exercise on force production, muscle activation and work economy. In addition this study investigated the rate of recovery comparing the active and passive recovery models and the association of the initial fitness levels of subjects. 16 (27 ± 4 years old) male reservists performed combined strength (5x10x70%RM leg-press) and endurance (5x1…
Modeling of differential admittance behaviour of thin amorphous semiconducting film
2012
The understanding of the electronic properties of thin oxide film is an important step toward the understanding of the mechanisms of film dissolution and breakdown as well as for their application in the field of electrolytic capacitors and solar energy conversion. From this point of view the correct location of the characteristic energy levels (flat band potential, Ufb, and conduction (valence) band edge EC (EV)), of a passive film/electrolyte junction is the preliminary task for a deeper understanding of the mechanism of charge transfer at oxide/electrolyte interface. At this aim the most frequently employed method to locate such characteristic energy levels of semiconductor oxide/electro…
Quadratic least-squares formulation for a local active noise control with stochastic domain and noise source
2012
A local active noise control method that uses stochastic numerical acoustical modeling is introduced. The frequency domain acoustical simulations are performed by a sequence solutions to Helmholtz equations approximated by FEM. The proposed ANC method maps microphone measurements linearly to the output signals of antinoise actuators. The matrix defining the linear mapping is optimized for each frequency to minimize expected value of the noise. The paper concentrates on defining the quadratic least-squares optimization problem for the minimization of the sound pressure field in the silet region. The formulation leads to a robust and accurate noise control in stochastic domains that has a sto…
Līdzjūtības pret sevi saistība ar emociju regulēšanas stratēģiju izvēli
2021
Pētījuma mērķis ir izpētīt saistības starp līdzjūtību pret sevi un emociju regulēšanas stratēģiju izvēli. Pētījumā tika aptaujāti 81 respondents vecumā no 18 līdz 70 gadiem, kuri aizpildīja divas sekojošas aptaujas: Iejūtības pret sevi skalu (Self-Compassion Scale (SCS), Neff, 2003), kuru Latvijā adaptējusi Liliāna Tamsone, 2015. gadā un Emociju regulācijas aptauju (Emotion Regulation Questionnaire, Gross & John, 2003), kuras sākotnējo veikusi Marija Morozova, 2011. gadā, un uzlabojumu veicis Emīls Ūdris un Edmunds Vanags 2017. gadā, kā arī demogrāfisko datu anketu. Iegūtie rezultāti uzrādīja pozitīvas saistības starp emociju regulācijas aptaujas Kognitīvās pārvērtēšanas apakškalu un Iejūtī…
Introduzione a: Il prisma delle passioni. Prospettive per un'antropologia delle passioni
2021
Il volume esplora il tema delle emozioni rivalutandolo in senso antropologico. A partire da approcci disciplinari diversi, come in un prisma che fa convergere l’attenzione sul fenomeno osservato rispettandone le molteplici sfaccettature, emerge dai saggi raccolti come la sfera emotiva rappresenti una chiave d’accesso privilegiata per la comprensione della natura umana.
Dom utracony, dom odzyskany... (?) : powrót do "małej ojczyzny" w wierszu Czesława Miłosza "Dwór"
2016
Czesław Miłosz’s poem Dwór [trans. Manor] may be understood as the author’s poetical recollection of visiting his homeland. This return results in a specific temporal and spatial perspective. A noiseless walk through a place which once was both close and well-known is an impulse for comparisons between the present and the past, and for personal thoughts of existential character. The artistic descriptions of the changes at the Nevezis river and the physical absence of the manor, positions time as the enemy of men and nature. This image finds its conclusion in the comparison of the man to the manor. As a consequence, the poem becomes a commentary of the inevitable passage of time and the need…
Mushrooms as biomonitors of heavy metals contamination in forest areas
2018
The aim of the research was to assess the level of contamination with heavy metals (manganese, iron, nickel, copper, zinc, cadmium and lead) in two forest areas selected in different places in Poland: the first one in the Swietokrzyskie Province (forests of the Staporkow Forest Division) and the second one in the Opolskie Province (forests of the Kup Forest Division). The degree of contamination of these forest areas with analytes was found using edible large-fruited mushrooms naturally occurring there - the research was carried out using passive biomonitoring method. Heavy metals in mushrooms (separately in stems and hats) as well as in soil samples were determined by atomic absorption spe…
