Adaptation of a tropical butterfly to a temperate climate

2018

Developmental plasticity enables organisms to cope with environmental heterogeneity, such as seasonal variation in climatic conditions, and is thought to affect a species’ capability to adapt to environments with novel seasonal and ecological dynamics. We studied developmental plasticity of the widespread tropical butterfly, Bicyclus safitza, which reaches the southern edge of its distribution in the temperate zone of South Africa. In wet–dry seasonal environments in tropical Africa, adults of Bicyclus butterflies are present all year round and exhibit discrete seasonal forms in alternating generations. We demonstrate that a population that colonized a more temperate climate region has adop…

Global urban environmental change drives adaptation in white clover

2022

Made available in DSpace on 2022-04-28T19:52:06Z (GMT). No. of bitstreams: 0 Previous issue date: 2022-03-18 Urbanization transforms environments in ways that alter biological evolution. We examined whether urban environmental change drives parallel evolution by sampling 110,019 white clover plants from 6169 populations in 160 cities globally. Plants were assayed for a Mendelian antiherbivore defense that also affects tolerance to abiotic stressors. Urban-rural gradients were associated with the evolution of clines in defense in 47% of cities throughout the world. Variation in the strength of clines was explained by environmental changes in drought stress and vegetation cover that varied am…

Successful adaptation of immigrants to Finland : can cultural fusion work?

2017

Immigration numbers in Finland are growing, more than doubling in the past decade, with immigrants arriving from increasingly diverse regions of the world. An attempt should be made to understand what are the factors that lead immigrants to finding happiness, and to mitigate the apparent rise in assimilation and anti-immigrant attitude in Finland. Most of the interviewees (n=16; 7 females, 9 males) have embedded themselves in dispersed communities, with connections from the workplace, studies, or common interests (e.g., religion, hobbies) that rarely including their immediate neighbors. Several reported a comfort in their own uniqueness. Some pointed to the kindness of Finns as integral to …

Climate change and reindeer management in Finland : Co-analysis of practitioner knowledge and meteorological data for better adaptation

2020

We studied interannual variability and changes over time in selected climate indices in the reindeer management area (RMA) in northern Finland. We present together the knowledge possessed by reindeer herders with information from meteorological measurements over three decades. The practitioner knowledge was gathered via a survey questionnaire addressing herder observations of long-term changes (approximately during the past 30 years) in climatic conditions and their impacts on herding during the four seasons. A set of temperature-, precipitation- and snow-related indices relevant for herding within the RMA was derived from spatially interpolated daily meteorological data (1981–2010). Climat…

Interpersonal relationships of immigrant students

2011

This study explores the interpersonal relationships of immigrant students. This is a current topic because immigration to Finland has increased rapidly and student groups are more diverse than ever before. The aim is to study immigrant students’ experiences and expectations of their interpersonal relationships and how they develop and maintain them, and also to understand how interpersonal relationships affect the immigrant students’ adaptation to the new environment. This study is qualitative. The theoretical part of the study is based on the theories related to interpersonal relationships, uncertainty management, and identity. The Stress-adaptation-growth dynamic process model of Kim (200…

Biological adaptation in light of the Lewontin–Williams (a)symmetry

2022

Neo-Darwinism characterises biological adaptation as a one-sided process, in which organisms adapt to their environment but not vice versa. This asymmetric relationship – here called Williams’ asymmetry – is called into question by Niche Construction Theory, which emphasises that organisms and their environments often mutually affect each other. Here we clarify that Williams’ asymmetry is specifically concerned with (quasi-) directed modifications towards phenotypes that increase individual fitness. This directedness – which drives the adaptive fit between organism and environment – entails far more than the mere presence of cause-effect relationships. We argue that difficulties with invoki…
