Testing different forms of regulation of yolk thyroid hormone transfer in pied flycatchers
Hormones transferred from mothers to their offspring are considered a maternal tool to prepare progeny for expected environmental conditions, increasing maternal and offspring fitness. To flexibly influence offspring, ...
Quantification of the Potential Impact of Glyphosate-Based Products on Microbiomes
<p><br></p><p>Glyphosate-based products (GBP) are the most common broad-spectrum herbicides worldwide. The target of glyphosate is the enzyme 5-enolpyruvylshikimate-3-phosphate synthase (EPSPS) in the shikimate pathway, ...
Effect of Juvenile Hormone on Resistance against Entomopathogenic Fungus Metarhizium robertsii Differs between Sexes
Juvenile hormone has been suggested to be a potential mediator in the trade-off between mating and insects' immunity. Studies on various insect taxons have found that juvenile hormone interferes with humoral and cellular ...
Impact of continuous predator threat on telomere dynamics in parent and nestling pied flycatchers
In addition to direct mortality, predators can have indirect effects on prey populations by affecting prey behaviour or physiology. For example, predator presence can increase stress hormone levels, which can have physiological ...
Northern geometrid forest pests (Lepidoptera: Geometridae) hatch at lower temperatures than their southern conspecifics: Implications of climate change
Climate change may facilitate shifts in the ranges and the spread of insect pests, but a warming climate may also affect herbivorous insects adversely if it disrupts the locally adapted synchrony between the phenology of ...
Systemic fungal endophytes and ploidy level in Festuca vivipara populations in North European Islands
<p>
Exploring the regional pattern of variation in traits driven by symbiotic interactions may provide insights to understand the evolutionary processes that operate over plant populations. Polyploidy, which is associated ...
Exposure to copper during larval development has intra- and trans-generational influence on fitness in later life
Anthropogenic pollution has a disadvantageous influence on various life-history traits. Although direct effects are well known, potential fitness-related trans-generational costs are less studied. Previously, empirical ...
Evaluating the personality structure of semi-captive Asian elephants living in their natural habitat
Data on personality for long-lived, highly social wild mammals with high cognitive abilities are rare. We investigated the personality structure of Asian elephants (Elephas maximus) by using a large sample of semi-captive ...
Tick distribution and tick-borne pathogens in Finland - The tick project of the University of Turku
<p>Ticks and tick-borne diseases are a growing problem in northern Europe and Russia. Surveys conducted in Russia, Sweden and Norway have revealed a northwards shift in distribution and an increase in tick abundance over ...
Mapping Floristic Patterns of Trees in Peruvian Amazonia Using Remote Sensing and Machine Learning
Recognition of the spatial variation in tree species composition is a necessary precondition for wise management and conservation of forests. In the Peruvian Amazonia, this goal is not yet achieved mostly because adequate ...
