For animals that synthesise their chemical compounds de novo, resources, particularly proteins, can influence investment in chemical defences and nitrogen-based wing colouration such as melanin. Competing for the same resources often leads to trade-offs in resource allocation. We manipulated protein availability in the larval diet of the wood tiger moth, Arctia plantaginis, to test how early life resource availability influences relevant life history traits, melanin production, and chemical defences. We expected higher dietary protein to result in more effective chemical defences in adult moths and a higher amount of melanin in the wings. According to the resource allocation hypothesis, we also expected individuals with less melanin to have more resources to allocate to chemical defences. We found that protein-deprived moths had a slower larval development, and their chemical defences were less unpalatable for bird predators, but the expression of melanin in their wings did not differ from that of moths raised on a high-protein diet. The amount of melanin in the wings, however, unexpectedly correlated positively with chemical defences. Our findings demonstrate that the resources available in early life have an important role in the efficacy of chemical defences, but melanin-based warning colours are less sensitive to resource variability than other fitness-related traits.

Nokelainen, Ossi; Silvasti, Sanni A.; Strauss, Sharon Y.; Wahlberg, Niklas; Mappes, Johanna
Natural selection generally favours phenotypic variability in camouflaged organisms, whereas aposematic organisms are expected to evolve a more uniform warning coloration. However, no comprehensive analysis of the phenotypic consequences of predator selection in aposematic and cryptic species exists. Using state-of-the-art image analysis, we examine 2800 wing images of 82 moth species accessed via three online museum databases. We test whether anti-predator strategy (i.e., camouflage or aposematism) explains intraspecific variation in wing colour and pattern across northern hemisphere moths. In addition, we test two mutually non-exclusive, ecological hypotheses to explain variation in colour pattern: diel-activity or dietary-niche. In this work, taking into account phylogenetic relationships, moth phenotypic variability is best explained by anti-predator strategy with camouflaged moths being more variable in wing patterning than aposematic species.

Nokelainen, Ossi; Winters, Sandra; Rowe, Zeke; Campos, Fernando A.; Wikberg, Eva C.; Howell, Natasha; Caro, Tim
Conspicuous coloration is often seen as the evolutionary consequence of either sexual selection or warning predators visually about prey defences, although not all conspicuous species fit this paradigm. Exceptions include several species of colobus monkeys whose black-and-white coloration, characteristic of larger colobines, has never been explained. Here, using photographs of black-and-white colobus (Colobus vellerosus) taken in the wild, quantitative image analysis, and vision modelling (acuity-corrected feline, chimpanzee, and raptor vision), we provide evidence that their coloration provides distance-dependent camouflage in natural forest environments. At all viewing distances, black-and-white colobus monkeys blend into their environment because of their high chromatic overlap with the background when viewed by ecologically relevant predator vision models which have low visual acuities. Additionally, for chimpanzee and felid vision, there was evidence of edge disruption at longer viewing distances. Our comparative analyses of different species of colobines do not support an association between black-and-white coloration and larger body mass or group size, but this may simply be due to the limited number of species within the family. We reason that black-and-white colobines gain visually protective coloration through background matching against felids, and also benefit through disruptive coloration against felids and chimpanzees but rely on these protective coloration mechanisms less against raptors.

Jos Pekka Olsbo saisi valita kenet tahansa illallisseurakseen, hän todennäköisesti valitsisi John Lennonin. Syynä ei olisi yksinomaan Olsbon Beatles-fanitus tai Lennonin elämänfilosofia. Kirjoitustensa perusteella John Lennon vaan vaikuttaa hemmetin hauskalta tyypiltä.

Avoimen tieteen ja tutkimuksen (AVOTT) kansallisen koordinaation työryhmät ovat tuottanut viime vuosien aikana useita linjauksia, suosituksia ja muita dokumentteja, jotka ovat luoneet perustaa tutkimusorganisaatioiden avoimen tieteen yhtenäisille käytännöille. Mutta millaisia vaikutuksia AVOTT-koordinaation dokumenteilla on ollut käytännön tasolla? Tähän artikkeliin on koottu tietoa neljän eri yliopiston tilanteesta.

Harjuniemi, Marja-Leena
Vuosi kuvailutyötä ja pää täynnä kysymyksiä. Miten tästä on saatu näin monimutkaista? Miten ikinä oppia RDA-standardin säännöt? Miksi todentavaa järjestelmää vieläkään ei ole? Entä mitä tekee tekoäly? Kuvailutyö on globaalisti merkityksellistä. Kyse on sisällöistä, tiedon tasa-arvosta – jopa demokratiasta. Tavoitteista ei kuitenkaan juuri puhuta. Ymmärrys avoimen kokoelmadatan merkityksestä, huoli kuvailutyön asemasta ja kuvailuasiantuntijoiden osaamisesta sai minut pohtimaan kuvailutyötä vähän enemmän. Kirjoituksen näkökulma painottuu tieteelliseen kirjastoon.

Linna, Anna-Kaarina; Ylönen, Irene; Salmi, Anna
As open access publishing has become more widespread and required by research funders and the research community, the management and monitoring of article processing charges (APCs) have emerged as an important task in research organisations around the world. Within this tendency, a question of the comprehensiveness of organisational APC monitoring has become relevant. This case study demonstrates how the comprehensiveness of in-house APC monitoring can be evaluated using international bibliographic information sources like Web of Science and Scopus, where it is possible to identify the corresponding author, as well as Unpaywall and DOAJ, which contain information about the open access statuses and APCs of articles. Based on study results, it can be assumed that the organisation’s in-house bookkeeping has succeeded in registering 52 percent of APC invoices while 48 percent have not been identified. The results show that the number of unreported publications that have been openly published and whose corresponding author is affiliated with the university is almost equal to those registered in the university’s institutional APC report. The study describes the stages of data collection and processing in order of implementation, which allows a similar review to be feasible in another organisation. At the end of the article, development proposals are presented for both the organisations’ in-house data collection and the content of publishers’ invoices.

Ten species of mosses (Bryophyta: Entosthodon obtusus, Entosthodon ulvinenii, Eurhynchiastrum diversifolium, Hedwigia emodica, Hedwigia mollis, Hygrohypnum styriacum, Plagiothecium rossicum, Polytrichum perigoniale, Tortella alpicola and Ulota intermedia) are presented as new for Finland. Cephalozia lacinulata, previously considered to be regionally extinct from Finland, is reported to being found again. New records in biogeographical provinces for 67 species of mosses and 34 species of liverworts are listed. Finally, 6 occurrences in provinces are removed due to misidentifications or missing specimens.

Viimeisen neljännesvuosisadan aikana eduskunnan valiokunnat kuulivat yli 10 000 kertaa tieteentekijöitä asiantuntijoina. Tutkijoiden osuus kaikista valiokuntien kuulemista henkilöstä on kuitenkin alle kymmenen prosenttia. Lisäksi tieteentekijöiden kuulemiset jakautuivat epätasaisesti valiokuntien, hallituskausien ja kuultujen tieteentekijöiden välillä.
