The evolution of temperature tolerance and invasiveness in a fluctuating thermal environment
2016
The consequences of the climate change on species are still uncertain, despite of intensive research. Currently, rising temperature is not the only concern, since the climate change scenarios also predict increases in the amount of disturbances, such as storms, floods, and thermal fluctuations. Disturbances have also been shown to affect species’ evolution, for example by selecting for traits that are advantageous in fluctuating environments but are also facilitating invasiveness. In this thesis, I study the consequences of evolving in a fluctuating thermal environment by utilizing bacterial microcosms. First I tested the effects of fluctuating vs. constant temperature on the evolution of t…

Publisher Copyright: © 2022 ACM. How do people interact with computers? This fundamental question was asked by Card, Moran, and Newell in 1983 with a proposition to frame it as a question about human cognition - in other words, as a matter of how information is processed in the mind. Recently, the question has been reframed as one of adaptation: how …
Early life of fathers affects offspring fitness in a wild rodent
2019
Intergenerational fitness effects on offspring due to the early life of the parent are well studied from the standpoint of the maternal environment, but intergenerational effects owing to the paternal early life environment are often overlooked. Nonetheless, recent laboratory studies in mammals and ecologically relevant studies in invertebrates predict that paternal effects can have a major impact on the offspring's phenotype. These non‐genetic, environment‐dependent paternal effects provide a mechanism for fathers to transmit environmental information to their offspring, and could allow rapid adaptation. We used the bank vole Myodes glareolus, a wild rodent species with no paternal care, t…

Role ambiguity among school principals in China and Finland
2012
This study explores the role-ambiguity phenomenon among public secondary school principals in China and Finland. Organizational dysfunction caused by role ambiguity in professional organizations has been studied since the 1960s (Kahn et al, 1964). Although role ambiguity occurs most frequently in educational organizations, few studies on role ambiguity are found on school leaders. This study contributes to this topic by building a multidimensional knowledge structure of role ambiguity among school principals. It applies a qualitative design with case study as its approach. The data was collected through ten individual interviews with upper secondary school principals in Shanghai and the Cen…
Who am i : reconstructing cultural identity upon reentry
2012
The topic of this thesis is reentry adaptation and its effects on an individual’s cultural identity. The purpose of the study is to find out what kinds of problems may arrive during reentry adaptation, how identity is changed as a result of intercultural experiences, as well as what kinds of communication strategies help the entire adaptation process. The aim of the study is to examine what kinds of factors should be taken into account during reentry in order to make it easier on the returnees. In addition the aim is to investigate how individuals are able to comprehend their new cultural identity and in which ways they are able to communicate the possible changes to friends and family at h…
The effect of spatial and temporal scale on camouflage in North African rodents
2022
Abstract Background matching, a common form of camouflage, is a widespread anti-predator adaptation that hinders detection or recognition by increasing the resemblance of prey to its environment. However, the natural environment is complex and both spatially and temporally variable, which constrains effective background matching as an anti-predator strategy. Here, using remote sensing data (publicly available satellite imagery), we investigated how variation of habitat parameters predicts background matching in 16 Sahara–Sahel rodent species across spatial and temporal scales. All fur colour parameters (hue, saturation and brightness) strongly matched the respective habitats of the differen…
