The impact of weather and the phase of the rodent cycle on breeding populations of waterbirds in Finnish Lapland

2016

Climate change may affect bird populations both directly by changing the weather conditions, and indirectly through changes in the food chain. While both theoretical and empirical studies have shown climate change having drastic impacts on polar areas, its consequences on Arctic bird species are still poorly known. Here we investigated how weather and changes in predator–prey interactions affected the annual growth rates of sub-Arctic birds by monitoring the breeding numbers of three duck and seven wader species in the alpine tundra of Finnish Lapland during 2005–2015 (except for 2006). We hypothesized that growth rates of waterbirds would be positively associated with warm and dry weather …

Sisäsiitoksella, eli pariutumisella lähisukulaisten kesken, on monia negatiivisia vaikutuksia sekä populaation että yksilön kelpoisuudelle. Sisäsiitos lisää homotsygotiaa ja mahdollistaa siten väistyvien haitallisten mutaatioiden ilmentymisen fenotyypissä sekä estää heterotsygotiasta johtuvaa paremmuutta lokuksissa, joissa on ylidominanssia. On osoitettu, että sisäsiittoisuus voi vaikuttaa koiraisiin ja naaraisiin eri tavalla siten, että toinen sukupuolista kärsii sisäsiitoksesta toista enemmän. Jotkut tutkimukset ovat näyttäneet, että sisäsiittoisuudella on voimakkaampi negatiivinen vaikutus koiraiden kuin naaraiden lisääntymiskykyyn, kun taas toiset osoittavat että naaraat kärsivät enemmä…

EDM and Ecstasy : the lived experiences of electronic music festival attendees

2016

This study aimed to provide a comprehensive exploration of the lived experiences of individuals who attended a multi-day electronic dance music festival. The present study was primarily interested in the perceived beneficial changes within the individual, following their festival experience. As well, we investigated if first time festival attendees perceived changes differed to those of returning individuals. Semi-structured qualitative interviews were used to collect data from 12 individuals who attended the 2015 Electronic Daisy Carnival in Las Vegas. Six participants were first-time attendees while the remaining 6 were individuals returning to the festival. The data was analysed using th…

EDM and Ecstasy: the lived experiences of electronic dance music festival attendees

2017

Attendance at large-scale music festivals has captivated a global interest in these spectacular experiences, yet little is known about the lasting benefits and personal changes individuals incur following this event. This study aims to provide a comprehensive exploration of the lived experiences of individuals who attended a multi-day electronic dance music festival. The present study was primarily interested in the perceived beneficial changes within the individual, following their festival experience. We investigated if first-time festival attendees perceived changes differed to those of returning individuals. Semi-structured qualitative interviews were used to collect data from 12 indivi…

Potential effects of transgenic cotton on soil ecosystem processes in Vietnam.

2008

This chapter concentrates on the potential effects of transgenic cotton on the soil ecosystem of three major cotton growing areas in Vietnam: the coastal lowlands region, the central highlands (eastern and western Truong Son Mountain Range) and the south-eastern region. Soils in these three regions are very different, so it will be necessary to assess the effects of transgenic cotton on typical soils from all three regions. The soils in the south-eastern region are Luvisols, Andosols and Acrisols. In the central highlands, the soils are mainly Luvisols, Rhodic Ferrasols and Haplic Acrisols. The soils in the coastal lowlands region are mainly delta soils, consolidated occasionally by grey li…

Hadronic light-by-light contribution to $(g-2)_\mu$ from lattice QCD with SU(3) flavor symmetry

2020

We perform a lattice QCD calculation of the hadronic light-by-light contribution to $(g-2)_\mu$ at the SU(3) flavor-symmetric point $m_\pi=m_K\simeq 420\,$MeV. The representation used is based on coordinate-space perturbation theory, with all QED elements of the relevant Feynman diagrams implemented in continuum, infinite Euclidean space. As a consequence, the effect of using finite lattices to evaluate the QCD four-point function of the electromagnetic current is exponentially suppressed. Thanks to the SU(3)-flavor symmetry, only two topologies of diagrams contribute, the fully connected and the leading disconnected. We show the equivalence in the continuum limit of two methods of computin…
