Responses and adaptations of collembolan communities (Hexapoda: Collembola) to flooding and hypoxic conditions
2009
Standard ecological methods (pitfall traps, trunk eclectors and soil cores) were used to evaluate collembolan community responses to different flooding intensities. Three sites of a floodplain habitat near Mainz, Germany, with different flooding regimes were investigated. The structures of collembolan communities are markedly different depending on flooding intensity. Sites more affected by flooding are dominated by hygrophilic and hygrotolerant species, whereas the hardwood floodplain is dominated by mesophilic species. The survival strategies of the hygrophilic and hygrotolerant species include egg diapause and passive drifting. The physiological adaptations to hypoxic conditions of sever…
The endangered freshwater pearl mussel Margaritifera margaritifera shows adaptation to a local salmonid host in Finland
2022
1. The freshwater pearl mussel Margaritifera margaritifera (FPM) is an endangered unionid which has a glochidium larva that attaches to the gills of Atlantic salmon Salmo salar or brown trout S. trutta, although some FPM populations have been shown to exclusively attach to only one of these species. The origin of host fish populations may be crucial for conservation actions for this mussel species, but the relative suitability of local (sympatric) and non- local (allopatric) salmonid populations as the hosts for FPM has been studied only rarely. We hypothesised that FPM glochidia would show adaptation to local salmonid strains and, there-fore, that they would be more successful (abundant, l…
Análisis de los motivos para la participación en actividades físicas de personas con y sin discapacidad
2006
Tradicionalmente, la actividad física adaptada ha sido utilizada para conseguir efectos terapéuticos y rehabilitadores en las personas con discapacidad. Actualmente, los educadores relacionados con la actividad física y deporte adaptado pretenden hacer ver a la sociedad en general que las personas con discapacidad pueden practicar actividades físicas y deportivas por las mismas motivaciones que las personas sin discapacidad. Para contribuir a este objetivo, y empleando como marco de referencia la teoría de las metas de logro, hemos analizado las motivaciones de una muestra de 80 personas con discapacidad funcional y otras 80 sin ningún tipo de discapacidad, todas ellas practicantes de activ…
Endocrine effects of sauna bath
2020
Sauna bath brings about numerous acute changes in hormone levels, partly akin to other stressful situations, partly specific for sauna. Norepinephrine increases in those accustomed to sauna bath. Sweating increases the production of antidiuretic hormone, and the renin-angiotensin system becomes activated. Of the anterior pituitary hormones, growth hormone (GH) and prolactin (PRL) secretion is increased. Also β-endorphin has been frequently reported to increase, whereas the responses of ACTH and cortisol are variable, probably depending on the type of sauna exposure. Sperm production decreases in particular in sauna-naïve men, but reduced fertility has not been associated with regular sauna …

Vuorokaudenajan ja harjoitusjärjestyksen vaikutukset hermostolliseen adaptaatioon, lihasvoimaan ja poikkipinta-alaan yhdistetyssä voima- ja kestävyys…
2014
Rytkönen, Tuomas (2015). Vuorokaudenajan ja harjoitusjärjestyksen vaikutukset hermostolliseen adaptaatioon, lihasvoimaan ja poikkipinta-alaan yhdistetyssä voima- ja kestävyysharjoittelussa. Liikuntabiologian laitos, Jyväskylän yliopisto. Valmennus- ja testausopin pro gradu -työ. 91 s. Monissa liikuntasuoritteissa tarvitaan sekä voimaa (V) että kestävyyttä (K). Yhdistetyssä V+K -harjoittelussa kohtuullinen harjoittelun kokonaisvolyymi on avain siihen, että voiman kehittyminen häiriintyy mahdollisimman vähän kestävyysharjoittelusta. Tässä tutkimuksessa V:aa ja K:ttä harjoitettiin 2–2,5 kertaa viikossa. Yksi aikaa säästävä tapa toteuttaa yhdistettyä V+K -harjoittelua on harjoittaa V:aa ja K:tt…
Heteroforiju izmaiņas pēc ilgstošas disociācijas un prizmu adaptācijs testa
2021
Maģistra darbs ir uzrakstīts angļu valodā uz 46 lapām. Tas satur 14 attēlus, 8 tabulas un 80 atsauces uz literatūras avotiem. Mērķis bija izvērtēt verģences adaptācijas ietekmi uz heteroforiju novērtējumu un prizmu adaptācijas testa pielietojumu klīniskajā praksē. Pirmajā daļā 40 dalībniekiem tika novērtētas heteroforija izmaiņas 2 minūšu laikā pēc disociācijas. Otrajā daļā tika novērtēta verģences adaptācija, izmantojot prizmu adaptācijas testu. Rezultāti parādīja, ka heteroforijas lielumu būtiski ietekmē disociācijas ilgums. Dalībniekiem ar diagnosticētu verģences anomāliju novēroja samazinātu verģences adaptāciju. Secinājums: verģences adaptācijai ir nozīmīga ietekme uz heteroforijas nov…
The role of individual and parental expectations in student-athletes’ career adaptability profiles
2022
To support holistic development, adolescent student-athletes are encouraged to integrate sport with education/academics (i.e., dual careers). Career adaptability, as a psychological resource, may help youth athletes cope with transitions and successfully manage their careers. Individuals with a plan and higher expectations for the future demonstrate higher career adaptability and are better prepared for the future. In the present study, we examined what kinds of distinct career adaptability profiles could be identified among youth athletes in Finland at the transition stage to a sports high school (i.e., specialized school for athletes). Moreover, we investigated whether youth athletes’ suc…
Psychometric properties and validation of the Polish adaptation of the Light Triad Scale
2019
BackgroundThe aim of the study was to examine the development and structural validation of the Polish version of the Light Triad Scale, which measures three factors: Faith in Humanity, Humanism, and Kantianism. This tool reflects caring and beneficent orienta-tion toward other people, which is demonstrated in everyday behaviour.Participants and procedureThe participants included 400 people aged between 18 and 80 (M = 29.17, SD = 10.60). To measure psychometric properties and for validation of the scale, we used the Polish Dirty Dozen scale and International Personality Item Pool-Big Five Aspect Scales.ResultsConfirmatory factor analysis, reliability analysis using α and ω coefficients, and …
Global Climate Policies, Local Institutions and Food Security in a Pastoral Society in Ethiopia
2020
This paper explores climate change adaptation within national policy priorities in a least developed country (LDC). The premise of the article is that when considering food security, climate is an exogenous trigger, while the deeper causes lie in social problems. Therefore, adaptation is subordinate to poverty alleviation. The paper examines how these two goals, climate adaptation and poverty alleviation, can be combined. Recent studies have shown that the most effective way to adapt to changing climate conditions in a poor country is to rely on local institutions that have established and sustainable mechanisms to deal with extreme climatic conditions. This research analyzes the stakeholde…
