Migratory behaviour and holding habitats of adult river lampreys (Lampetra fluviatilis) in two Finnish rivers

2015

The effect of environmental factors on migratory activity of adult river lampreys entering the Kalajoki and Perhonjoki, rivers in Finland, for spawning was studied using correlation and regression analyses. Telemetric tracking of 60 individuals was utilized to study the migratory patterns and holding habitat requirements of adult river lampreys. The increases in the river discharge, wind forcing towards the river mouth and speed and magnitude of river water cooling had positive effects on the numbers of lampreys entering the rivers whereas the increase in the illumination intensity of the moon had a negative effect on their migration activity. Radio-tagged lampreys typically passed slow-flo…

Olfactory cues and the value of information : Voles interpret cues differently based on recent predator encounters

2018

Prey strategically respond to the risk of predation by varying their behavior while balancing the tradeoffs of food and safety. We present here an experiment that tests the way the same indirect cues of predation risk are interpreted by bank voles, Myodes glareolus, as the game changes through exposure to a caged weasel. Using optimal patch use, we asked wild-caught voles to rank the risk they perceived. We measured their response to olfactory cues in the form of weasel bedding, a sham control in the form of rabbit bedding, and an odor-free control. We repeated the interviews in a chronological order to test the change in response, i.e., the changes in the value of the information. We found…

Tutkielmassa tarkastellaan sarjakuvahahmojen rakentumista monitahoisena semioottis-kognitiivisena prosessina, jossa sarjakuvakielen erilaiset merkit yhdistyvät muista medioista tuttuihin henkilöhahmokonventioihin ja lukijoiden ihmiskäsityksiin. Suurennuslasin alla ovat erityisesti angloamerikkalaiset sarjakuvaromaanit ja kognitiiviset henkilöhahmoteoriat. Tutkimuskysymykset kiteytyvät siihen, kuinka irralliset kuva- ja tekstielementit yhdistetään ajatusrakennelmiksi, jotka sekä muistuttavat että eivät muistuta käsityksiämme todellisista ihmisistä. Koska sarjakuvahahmoista ei ole luotu aiempaa teoriaa, tutkimuksessa luetaan ristiin yhtäältä kirjallisuuden henkilöhahmoteorioita ja toisaalta y…

Research data supporting "Social learning within and across predator species reduces attacks on novel aposematic prey"

2019

This data is from the experiment that investigated how wild-caught blue tits and great tits use conspecific and heterospecific information about unpalatable prey, published at the Journal of Animal Ecology (2020). The experiment was conducted at the Konnevesi Research Station from October to December 2017. Sheet 1 (“Main experiment”) contains data from the main avoidance learning experiment. Sheets 2 (“Symbol preference blue tits”) and 3 ("Symbol visibility blue tits") contain data of blue tits' symbol choices in initial preference and visibility tests.

Not just the sum of its parts : Geographic variation and nonadditive effects of pyrazines in the chemical defence of an aposematic moth

2022

Chemical defences often vary within and between populations both in quantity and quality, which is puzzling if prey survival is dependent on the strength of the defence. We investigated the within- and between-population variability in chemical defence of the wood tiger moth (Arctia plantaginis). The major components of its defences, SBMP (2-sec-butyl-3-methoxypyrazine) and IBMP (2-isobutyl-3-methoxypyrazine), are volatiles that deter bird attacks. We hypothesized that (1) variation in the chemical defences of male wood tiger moths reflects the local predation pressure; (2) observed differences in quantity and quality of defence among populations have a genetic basis; and (3) increasing con…
