Prenatal Transfer of Gut Bacteria in Rock Pigeon
Vertebrates evolved in concert with bacteria and have developed essential mutualistic relationships. Gut bacteria are vital for the postnatal development of most organs and the immune and metabolic systems and may likewise ...
Early weaning increases aggression and stereotypic behaviour in cats
Behaviour problems are common in companion felines, and problematic behaviour may be a sign of chronic stress. In laboratory animals, early weaning increases the risk for aggression, anxiety, and stereotypic behaviour. ...
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 ...
Spatial and seasonal variation in reproductive indices of the clupeids Limnothrissa miodon and Stolothrissa tanganicae in the Congolese waters of northern Lake Tanganyika
Knowledge on the reproductive biology of the endemic clupeids Limnothrissa miodon and Stolothrissa tanganicae, two main target species of the pelagic fisheries of Lake Tanganyika, is constrained by fragmented monitoring ...
Both male and female identity influence variation in male signalling effort
<p>
Conclusion: Despite the plasticity in male courtship effort, courtship displays had the potential to reliably convey information about the male to mate-searching females. Our experiment therefore underscores the ...
Moths and butterflies (Insecta: Lepidoptera) of the Russian Arctic islands in the Barents Sea
<p>Faunistic data are scarce for the Lepidoptera from the Arctic islands of European Russia. New sampling and revision of the earlier findings have revealed the occurrence of 60 species of moths and butterflies on Kolguev, ...
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 ...
Can Larvae of Forest Click Beetles (Coleoptera: Elateridae) Feed on Live Plant Roots?
Simple SummaryDetailed natural history information is still lacking for many species of soil-dwelling invertebrates. We asked whether the larvae (wireworms) of two click beetle species, which are most abundant in European ...
