Eco-physiological aspects of adaptation to seasonal environments : the latitudinal range expansion of the Colorado potato beetle across Europe

Casting Robotic end-effectors to reach far objects in space and planetary missions
2006
In this paper we present work aimed at developing a compact robotic device able to reach objects at far distance.The work is based on the idea of casting manipulation, and that allows to deploy an end-effector at large distances from the robot’s base by throwing (casting) it and controlling its ballistic flightusing forces transmitted through a light tether connected to the end-effector itself.

Collaborative Design Rational and Social Creativity in Cultures of Participation
2011
The rise in social computing has facilitated a shift from consumer cultures, focused on producing finished media to be consumed passively, to cultures of participation, where people can access the means to participate actively in personally meaningful problems. These developments represent unique and fundamental opportunities and challenges for rethinking and reinventing design rationale and creativity, as people acclimate to taking part in computer-mediated conversations of issues and their solutions. Grounded in our long-term research exploring these topics, this paper articulates arguments, describes and discusses conceptual frameworks and system developments (in the context of three cas…
Methods for territorial intelligence
2006
Quantitative methods which are used by social sciences for thirty years can provide tools to help territorial actors better managing their territories. This short paper outlines an inventory of the kinds of methods that are usable within this framework.
Adaptation to stressful environments : invasion success of the Colorado potato beetle (Leptinotarsa decemlineata)
2018
Biological invasions, specifically human-induced dispersals, are one of the major threats to our biodiversity and are predicted to increase. Invasive pests provide an opportunity to study whether adaptation to human-induced environments could promote invasions to other human-induced environments. One major anthropogenic selection pressure is created by pesticides, and pests can be exposed to various pesticides in their native, as well as introduced, ranges. I investigated whether exposure to anthropogenic selection (i.e. insecticides and herbicides) and exposure to multiple anthropogenic stressors selects for higher stress tolerance. I also tested whether parental prolonged diapause or inse…
Studentu folklora Latvijas Universitātes Humanitāro zinātņu fakultātē
2015
Bakalaura darbs „Studentu folklora Latvijas Universitātes Humanitāro zinātņu fakultātē” veikts sociālo grupu pētniecības laukā. Pētījuma centrā – Latvijas Universitātes Humanitāro zinātņu fakultātes studentu vidū pastāvošā folklora un tradīcijas. Darba mērķis – ar anketēšanas metodi un padziļinātu studentu daiļrades izpēti sociālajos tīklos apzināt un salīdzinošā aspektā raksturot studentu folkloru Latvijas Universitātes Humanitāro zinātņu fakultātē, uzmanību vēršot uz dažādiem tās specifiku veidojošiem faktoriem, tradīcijām un studentu vidē funkcionējošajiem mutvārdu un rakstveida folkloras tekstiem. Darba pirmajā nodaļā studenti raksturoti socialo grupu pētniecības aspektā, uzmanību vēršo…
Aizsarglietu stāstījumu folklora Latgalē (pēc 2018. un 2019. gada lauka pētījumu materiāliem)
2019
Bakalaura darba tēma ir “Aizsarglietu stāstījumu folklora Latgalē (pēc 2018. un 2019. gada lauka pētījumu materiāliem)”. Bakalaura darba mērķis bija noskaidrot, kas ir raksturīgs aizsarglietu stāstījumu folklorai Latgalē, kāda ir tās specifika, vai un kā ir transformējušās ar aizsarglietām saistītās latviešu tautas tradīcijas, salīdzinot ar latviešu folkloras materiālu. Darbs sastāv no ievada, trim nodaļām un, secinājumiem. Pirmajā nodaļā tika analizēti aizsarglietu stāstījumi, kas vēsta par mājas aizsardzību (māju, īpašumu aizsargājošiem augiem, ornamentālajām zīmēm, baznīcā svētītajām aizsarglietām), un tika noskaidroti aizsarglietu izmantošanas dažādie nolūki. Otrajā nodaļā tika raksturo…
Improved camouflage through ontogenetic colour change confers reduced detection risk in shore crabs
2019
Abstract Animals from many taxa, from snakes and crabs to caterpillars and lobsters, change appearance with age, but the reasons why this occurs are rarely tested.We show the importance that ontogenetic changes in coloration have on the camouflage of the green shore crabs (Carcinus maenas), known for their remarkable phenotypic variation and plasticity in colour and pattern.In controlled conditions, we reared juvenile crabs of two shades, pale or dark, on two background types simulating different habitats for 10 weeks.In contrast to expectations for reversible colour change, crabs did not tune their background match to specific microhabitats, but instead, and regardless of treatment, all de…
Supplementary data to: Context-dependent coloration of prey and predator decision making in contrasting light environments
2021
A big question in behavioural ecology is what drives diversity of colour signals. The dataset covers the testing of the context-dependent predator selection on prey coloration. In the first experiment, detectability of artificial visual stimuli to blue tits (Cyanistes caeruleus) was tested by manipulating stimulus luminance and chromatic context of the background. In the second experiment, the effect of two light environments on the survival of aposematic, colour polymorphic wood tiger moth (Arctia plantaginis) was tested. For detailed description of the material, methods, and results of the study, see the article.
