Hard to catch: Experimental evidence supports evasive mimicry
2021
Most research on aposematism has focused on chemically defended prey, but the signalling difficulty of capture remains poorly explored. Similar to classical Batesian and Müllerian mimicry related to distastefulness, such ‘evasive aposematism' may also lead to convergence in warning colours, known as evasive mimicry. A prime candidate group for evasive mimicry areAdelphabutterflies, which are agile insects and show remarkable colour pattern convergence. We tested the ability of naive blue tits to learn to avoid and generalizeAdelphawing patterns associated with the difficulty of capture and compared their response to that of birds that learned to associate the same wing patterns with distast…
Multidimensional instruments with an integral approach to identify frailty in community-dwelling people: protocol for a systematic psychometric review
2019
IntroductionAn increasing number of investigations highlight the complex nature of frailty; therefore, the use of multidimensional assessment instruments could be useful in clinical decision-making. Frail people are found mainly in the community setting which is why this is the ideal environment for early screening and intervention. For this purpose, it is necessary to have valid, time-effective and easy-to-use frailty assessment instruments. The aim of this review is to critically appraise, compare and summarise the quality of the measurement properties of all multidimensional instruments with an integral approach to identify frailty in community-dwelling people.Methods and analysisMedline…
Lepoaineenvaihdunnan määrittäminen epäsuoralla kalorimetrialla ja naisurheilijan oireyhtymä
2018
Johdanto. Epäsuora kalorimetria on yleinen tapa määrittää lepoaineenvaihdunta (LAVESK). Tarkoituksena on tutkia LAVESK:n toistettavuutta ja pätevyyttä kannettavalla hengityskaasuanalysaattorilla määritettynä. Tutkimuksen toisessa osassa tutkitaan antropometristen ja hormonaalisten muuttujien yhteyttä lepoaineenvaihduntaan naiskestävyysjuoksijoilla. Naisurheilijan oireyhtymässä alhainen energiansaatavuus, kuukautiskierron häiriöt sekä alentunut luuston massa yhdistyvät toisiinsa. Alhainen energiansaatavuus on yhteydessä adaptiiviseen termogeneesiin, jolloin havaitaan muutoksia myös lepoaineenvaihdunnassa. Menetelmät. LAVESK:n toistettavuuden osalta aineisto koostuu terveistä nuorista aikuisi…

Impacts of reduced Lepidurus arcticus availability on brown trout life history traits in a mountain reservoir
2020
Lepidurus arcticus (the Arctic tadpole shrimp) is a vulnerable keystone species in Arctic and alpine water bodies where its occurrence and population size may influence the viability and life history traits of resident salmonids. Using data from a Norwegian mountain hydropower reservoir, Aursjoen, we illustrate how reduced availability of L. arcticus as prey resulted in the reduced condition, growth and delayed maturation of resident brown trout (Salmo trutta). We further link changes in the relative abundance of L. arcticus as prey to changing reservoir conditions, e.g. water level changes in the spring period, thereby establishing an indirect link between reservoir operation regimes and b…

Selection of spawning substratum by European river lampreys (Lampetra fluviatilis) in experimental tanks
2014
The selection of spawning substratum by the river lamprey (Lampetra fluviatilis) was studied in two experimental tanks with different flow conditions. In both tanks, four gravel sizes mixed with 15% sand were available to the test animals. In the tank with the lower current speed, lampreys selected in favour of the finest (2–8 mm) gravel size available against gravel sizes 4–20 mm and 8–40 mm. Selection was also significantly different in the tank with higher current speed where selection against the medium-sized substratum (4–20 mm) was evident, but there were no differences between selection for gravel sizes 2–8 mm, 2–40 mm and 8–40 mm relative to availability. Substratum selection and ob…
