The importance of study duration and spatial scale in pathogen detection - evidence from a tick-infested island
Ticks (Acari: Ixodoidea) are among the most common vectors of zoonotic pathogens worldwide. While research on tick-borne pathogens is abundant, few studies have thoroughly investigated small-scale spatial differences in ...
Crowdsourcing-based nationwide tick collection reveals the distribution of Ixodes ricinus and I. persulcatus and associated pathogens in Finland
A national crowdsourcing-based tick collection campaign was organized in 2015 with the objective of producing novel data on tick distribution and tick-borne pathogens in Finland. Nearly 20 000 Ixodes ticks were collected. The collected material revealed the nationwide distribution of I. persulcatus for the first time and a shift northwards in the distribution of I. ricinus in Finland. A subset of 2038 tick samples containing both species was screened for Borrelia burgdorferi sensu lato (the prevalence was 14.2% for I. ricinus and 19.8% for I. persulcatus), B. miyamotoi (0.2% and 0.4%, respectively) and tick-borne encephalitis virus (TBEV; 0.2% and 3.0%, respectively). We also report new risk areas for TBEV in Finland and, for the first time, the presence of B. miyamotoi in ticks from mainland Finland. Most importantly, our study demonstrates the overwhelming power of citizen science in accomplishing a collection effort that would have been impossible with the scientific community alone....
Biologian kenttäopetus yliopistoissa: yhteistyöllä uuteen nousuun
<p>Kenttäkurssit ovat keskeinen osa biologian ja lähitieteiden opetusta yliopistoissa. Luonnossa tapahtuva opetus kehittää sekä ymmärrystä tieteenalan teoreettisista perusteista että ammatillisia käytännön taitoja. ...
Local adaptations and phenotypic plasticity may render gypsy moth and nun moth future pests in northern European boreal forests
<p>Phenotypic plasticity and local adaptations are important factors in predicting range expansions and shifts of pest insects in a changing climate. We reared two lepidopteran forest pests, <i>Lymantria monacha</i> ...
