The Department of Biosciences invites applications for
FIVE POSTDOCTORAL RESEARCHERS
in population/community ecology and statistical ecology for a fixed term of three years. There will be a trial period of four months in the beginning. The post doc positions are part of the Research Centre for Ecological Change and are funded by the Jane and Aatos Erkko Foundation for 1.1.2018-31.12.2020. PIs of the Centre are prof. Anna-Liisa Laine, prof. Otso Ovaskainen, prof. Tomas Roslin, assist. prof. Jarno Vanhatalo and dr Marjo Saastamoinen. The starting date is 1.1.2018, but a later starting date can be negotiated.
The overreaching aim of the Centre is to generate a coordinated analysis of long-term ecological data to understand impacts of global change. To unravel how populations and interactions between species in nature are responding to ongoing environmental change, the project takes advantage of the unique long-term datasets collected in Finland. The centre also develops state-of-the-art methodology for analysing long-term spatially structured data sets within a joint species distribution modeling framework.

3 POST DOC POSITIONS IN POPULATION/COMMUNITY ECOLOGY
We are seeking three post docs to analyse extensive ecological datasets. The successful candidates will take part in developing the specific research questions, and in linking spatial and temporal data on the abundance and distribution of species and on community composition to data on habitat structure, population harvesting, fragmentation, land use and/or weather. Examples of questions of interest include the role of environmental change on biodiversity in different habitats, on the spread of pests, disease, and invasive species, on the threat status of endangered species, and on potential mismatches in phenology among interacting species. The data and research questions concern both aquatic and terrestrial ecosystems. The focus of the specific research questions can be modified in accordance with the background and interests of the candidate.
The successful applicant should have completed a PhD in ecology or a related field, and have a strong background in statistics, spatial statistics, and/or GIS. We seek candidates with excellent written and verbal communication skills, and the ability to conceive, execute and complete research projects, and to think independently and creatively. The post docs will work as a part of a team at the Centre but also with researchers from other environmental institutes. Overall, excellent social skills are required for extensive collaborations.
For more information, contact prof. Anna-Liisa Laine, prof. Tomas Roslin and/or Dr. Marjo Saastamoinen by email: anna-liisa.laine@helsinki.fi, tomas.roslin@helsinki.fi, marjo.saastamoinen@helsinki.fi
The salary of the successful candidate will be based on level 5 - 6 of the demands level chart for teaching and research personnel in the salary system of Finnish universities. In addition, the appointee will be paid a salary component based on personal performance. The starting salary will be ca. 3300 - 3800 euros/month, depending on the appointee’s qualifications and experience.
Please submit your application using the University of Helsinki Recruitment System. Please attach the following documents as a single pdf file: motivational letter (max 1 page), CV (max 2 pages) and publication list. Include also contact information of two persons who can provide a reference letter based on request.
The deadline for submitting the application is 8 October 2017.

2 POST DOC POSITIONS IN STATISTICAL ECOLOGY
The post docs take part in the development of statistical methods for analyzing long-term ecological data and in statistical analyzes within the Research Centre for Ecological Change.
The methodological work focus on development of Hierarchical Modelling of Species Communities (HMSC) and hierarchical multivariate Gaussian processes. HMSC is a joint species distribution modelling framework that can be used for the statistical analysis of data on species occurrence, environmental covariates, functional traits and phylogenetic relationships. HMSC can be applied to hierarchical, spatial and temporal study designs, and it applies to many kinds of response data (presence/absence, counts, etc.). Gaussian processes are flexible and versatile modeling approach that are emerging to statistical ecology as tools for species distribution and population dynamics modeling. Gaussian processes are used to model spatial and spatiotemporal heterogeneity in data and describe species responses to their environment in nonparametric manner.
For recent methodological publications, see the reference list at the end. For the R and MATLAB implementations of HMSC, see the project’s www-page https://www.helsinki.fi/en/researchgroups/metapopulation-research-centre/hmsc
A successful post doc candidate will have experience in the development and application of Bayesian methods for computationally challenging problems. In particular, prior experience in multivariate generalized linear mixed models, factor models and/or Gaussian processes is highly valued. A successful candidate will also have experience in scientific computing. Prior experience in ecology is not necessary, but is counted as an advantage. The exact direction to which the post doc will develop HMSC and Gaussian process models can be agreed upon based on the experience and interests of the candidate

Biotieteiden laitos hakee
Tietokantakoordinaattoria (Database manager)
määräaikaiseen työsuhteeseen kolmeksi vuodeksi 1.1.2018 alkaen tai sopimuksen mukaan. Töiden alussa on neljän kuukauden koeaika.
Tehtävä sijoittuu Center for Ecological Change-hankkeeseen jonka Jane ja Aatos Erkon säätiö on rahoittanut vuosille 2018-20. Hankkeen tavoitteena on koota yhteen ja analysoida luonnon ekologisia pitkäaikaisaineistoja, jotta ymmärtäisimme paremmin kuinka yksittäiset lajit sekä lajien väliset vuorovaikutukset reagoivat ympäristönmuutokseen. Ryhmänjohtajina hankkeessa toimivat prof. Anna-Liisa Laine, prof. Otso Ovaskainen, prof. Tomas Roslin, apulaisprof. Jarno Vanhatalo ja akatemiatutkija Marjo Saastamoinen. Lisätietoja hankkeen verkkosivuilta:
https://www.helsinki.fi/en/researchgroups/research-centre-for-ecological-change
Tietokantakoordinaattori kerää sekä pitää yllä Center for Ecological Change-hankkeen tutkimuksessa käytettäviä tietoaineistoja ja muokkaa näitä aineistoja tutkimuksessa hyödynnettävään muotoon.

Tehtävän palkkaus perustuu yliopistojen palkkausjärjestelmän muun kuin opetus- ja tutkimushenkilöstön vaativuuskehikon tasoille 8-10. Lisäksi maksetaan henkilökohtaiseen suoriutumiseen perustuva palkanosa. Kokonaispalkka on n. 2700-3800 e/kk. Lopullinen tehtävän taso määräytyy valittavan henkilön osaamisen mukaan. Työ alkaa 1.1.2018 tai toisin sovittuna ajankohtana.
Hakemukset on jätettävä viimeistään 8.10.2017.
Hakemukseen on liitettävä yhtenä pdf-tiedostona hakukirje (max 1 sivu), ansioluettelo (max 2 sivua) ja mahdollinen julkaisulista. Hakemuksessa on oltava myös kahden suosittelijan yhteystiedot, joilta voi tarvittaessa pyytää suosittelukirjeen.
Lisätietoja tehtävästä antaa prof. Anna-Liisa Laine (anna-liisa.laine@helsinki.fi).
