Interkingdom Gut Microbiome and Resistome of the Cockroach Blattella germanica
2021
Cockroaches are intriguing animals with two coexisting symbiotic systems, an endosymbiont in the fat body, involved in nitrogen metabolism, and a gut microbiome whose diversity, complexity, role, and developmental dynamics have not been fully elucidated. In this work, we present a metagenomic approach to study Blattella germanica populations not treated, treated with kanamycin, and recovered after treatment, both naturally and by adding feces to the diet, with the aim of better understanding the structure and function of its gut microbiome along the development as well as the characterization of its resistome.
Size-dependent aggression towards kin in a cannibalistic species.
2022
Abstract In juveniles extreme intraspecies aggression can seem counter-intuitive, as it might endanger their developmental goal of surviving until reproductive stage. Ultimately, aggression can be vital for survival, although the factors (e.g., genetic or environmental) leading to the expression and intensity of this behavior vary across taxa. Attacking (and sometimes killing) related individuals may reduce inclusive fitness; as a solution to this problem, some species exhibit kin discrimination and preferentially attack unrelated individuals. Here, we used both experimental and modeling approaches to consider how physical traits (e.g., size in relation to opponent) and genetic relatedness …
Expanding Acutuncus : Phylogenetics and morphological analyses reveal a considerably wider distribution for this tardigrade genus
2023
The tardigrade genus Acutuncus has been long thought to be an Antarctic endemism, well adapted to this harsh environment. The Antarctic endemicity of Acutuncus was recently dispelled with the description of Acutuncus mariae Zawierucha, 2020 found in the Svalbard archipelago. The integrated analyses on two newly found Acutuncus populations from UK and Italy, and a population of Acutuncus antarcticus found close to its type locality allowed us to expand the climatic and geographic range of the genus Acutuncus. These findings also allowed us to re-evaluate the morphological diagnoses of Acutuncus and accommodate it in the newly proposed monotypic family Acutuncidae fam. nov. Two new Acutuncus …
The toughest animals of the Earth versus global warming: Effects of long-term experimental warming on tardigrade community structure of a temperate d…
2021
Abstract Understanding how different taxa respond to global warming is essential for predicting future changes and elaborating strategies to buffer them. Tardigrades are well known for their ability to survive environmental stressors, such as drying and freezing, by undergoing cryptobiosis and rapidly recovering their metabolic function after stressors cease. Determining the extent to which animals that undergo cryptobiosis are affected by environmental warming will help to understand the real magnitude climate change will have on these organisms. Here, we report on the responses of tardigrades within a five‐year‐long, field‐based artificial warming experiment, which consisted of 12 open‐to…
Allium sphaeronixum (Amaryllidaceae), A New Species from Turkey
2023
In this paper, Allium sphaeronixum, a new species of the sect. Codonoprasum from Turkey, is described and illustrated. The new species is endemic to Central Anatolia, limited to the area of Nevşehir, where it grows on sandy or rocky soil at an elevation of 1000–1300 m a.s.l. Its morphology, phenology, karyology, leaf anatomy, seed testa micromorphology, chorology, and conservation status are examined in detail. The taxonomic relationships with the closest allied species, A. staticiforme and A. myrianthum, are also highlighted and discussed.
Children's perception of emotion in music : a cross-cultural study
2015
Previous research revealed that Western lullabies and children’s songs are mostly in the major mode, and children demonstrate a positive-major/negative-minor connotation that conforms to the conventional stereotype. The aim in this current study is to analyze the same topic in Finland and Iran where most lullabies are in the minor mode. The overarching question addressed is whether or not cultural background and the music mode, a child tends to be exposed to early in life affects later emotional responses to different music modes. Quantitative data was obtained from 5-8-year old children (n=44) and mothers (n=39) in mentioned countries. Background questionnaire and questions about twelve Fi…
Exploring the potential of an air transport eco-label
2018
Air transport plays a vital role in tourism because it makes long-haul destinations accessible and more frequent vacations possible. Despite its benefits, air travel extensively contributes to climate change. Behavioural change is seen as a key driver in mitigating the environmental impacts of air transport. One way to encourage behavioural change is the use of eco-labels. This paper presents the idea of introducing an air transport eco-label. It explores the idea’s potential and realization through the thematic analysis of 12 interviews with airline industry experts. The results indicated a need for an air transport eco-label. It could help build awareness among air travellers by providing…
Consumption behavior of eco-friendly products and applications of ICT innovation
2021
The purchase of eco-friendly products is encouraged by the governments due to its contributions to the sustainable development of the environment. It is therefore important to examine factors influencing the purchase of eco-friendly products. Based on the attitude-behavior-context (ABC) theory, this paper constructs a conceptual model, which explores how a consumer’s perceived effectiveness affects individuals’ purchase of eco-friendly products. In details, this paper attempts to examine the mediating role of consumption attitude of eco-friendly products, as well as the moderating effect of applications of information and communication technologies (ICT) innovation. Moreover, by building a …
The Developmental Dynamics between Interest, Self-concept of Ability, and Academic Performance
2014
Abstract. Only a few studies have examined the direction of associations between academic achievement, interest, and sel f-concept of ability simultaneously by using longitudinal data over several school years. To exam ine the cross-lagged relationships between students’ interest, self-concept of ability, and performance in mathematics and reading, longitudinal data from Grade 1 to Grade 7 of comprehensive school was gathered from 216 students. The results showed that, in both reading and math, performance predicted students’ subsequent self-concept of ability. Some evidence was also found that math performance predicts subsequent interest in mathematics, and that self- concept of math abil…
Who are the Showroomers? Socio-Demographic Factors Behind the Showrooming Behavior on Mobile Devices
2022
This quantitative study focuses on socio-demographic variables and their associations with different forms of showrooming behavior. The purpose of this study is to find which consumer groups based on age, gender, and income level are demographically the most probable showroomers, and how much each of these variables explain showrooming. The data used is a structured online survey from 1,028 Finnish omnichannel consumers aged between 18 and 75 years. We compare the means of demographic groups’ shares on different aspects of showrooming, and then use partial least squares structural equation modeling with confirmatory factor analysis to see how much each of the variables explain showrooming. …
