Heritability of dispersal in a rapidly spreading invasive spider

چکیده
Dispersal is an inseparable feature of animal life and a major determinant species distributions range dynamics. However, the role genetic architecture dispersal behaviour, hence potential for its evolution in range-expanding species, poorly understood. Here, we aimed to determine heritability behaviour invasive dwarf spider, Mermessus trilobatus , which has undergone rapid expansion Europe last few decades. Our results showed that spider traits were repeatable parental generation heritable through both dam sire. Behaviours similarly female male offspring. Interestingly, offspring highly dispersive dams sires exhibited almost three times higher propensity than at least one low-dispersive parent. The substantially high strictly vagile indicates recessive inheritance this species. Recessive could favour invasiveness by facilitating inbred founder populations invasion front returning nonexaggerated mobility soon after increase diversity. • appeared be recessively inherited spider. Variation was present despite presumably small population. On average sire contributed 37% individual variation dispersal. Spiders' consistent level. There evolve front.

COVID-19: A New Virus as a Potential Rapidly Spreading in the Worldwide
Covid-19 is a novel virus with high affinity to spread in the community. In December 2019, it was first identified in Wuhan, China. The symptoms are non-specific, so fever, cough, dyspnea, are prominent features. Respiratory failure and mortality have also been reported. The most common lung CT scan findings are bilateral ground glass opacities.
متن کامل'Heritability' of dispersal propensity in a patchy population.
Although dispersal is often considered to be a plastic, condition-dependent trait with low heritability, growing evidence supports medium to high levels of dispersal heritability. Obtaining unbiased estimates of dispersal heritability in natural populations nevertheless remains crucial to understand the evolution of dispersal strategies and their population consequences. Here we show that dispe...
متن کاملIsotope evidence for preferential dispersal of fast-spreading invasive gobies along man-made river bank structures.
Invasive round goby Neogobius melanostomus and bighead goby Ponticola kessleri have successfully colonized freshwater and coastal habitats worldwide. The objective was to use stable isotope analyses to study the foraging and movement of both species at small spatial scales in the Upper Danube River, considering 861 samples from two different years, seasons and sides of the river in an area wher...
