A set of code functions and commands used to convert data provided in the primary format into the SPI-Birds' standard format. A pipeline usually has a hierarchical structure (outputs of one component of the processing sequence are fed to the next step) and often is modular (non-necessary components can be removed or changed to modify the final structure of output data). SPI-Birds' pipelines are coded in R (and sometimes SQL where convenient) and available on our GitHub pipeline repository.

Data stored locally by each research group (i.e., data owner). Primary data might differ from raw data because of (a) errors made during transcribing raw data into primary data or (b) correction of obvious errors in raw data during transcribing them into primary data (c) primary data contain some derivate of primary data (e.g. average value for a repeated measurement of an individual). Source: Culina et al. 2021.

A data hub or repository of (meta)data on individually marked birds collected through (often long-term) field studies of bird populations in the wild. Metadata of all study sites part of SPI-Birds are available here; data can be requested (and used upon consent by data owners) by anyone within or outside the SPI-Birds Network.

A network of researchers who study and monitor populations of individually marked birds, and collaborate to make their data, and science in general, more FAIR. This includes the SPI-Birds team members (i.e., coordinators, developers, designers) as well as all data owners whose data are hosted at SPI-Birds.

A standard protocol for the collection of individual-level bird data, defined and shaped by the SPI-Birds Network. This protocol is the foundation of the pipelines that convert data owners' primary data format into SPI-Birds' standard data format, as well as as a guideline for people who wish to establish a new field site for monitoring individual birds.

A format agreed upon within the research community to record and archive data. The standard format defines the way data are organised among different tables, the vocabularies used to describe the data elements (names of the variables) and conventions used to express the values of the variables.

Marcel E. Visser
Marcel is the head of the Animal Ecology Department at the Netherlands Institute of Ecology (NIOO-KNAW) and he is widely recognized as a world-leading expert on the ecological and evolutionary impact of anthropogenic environmental changes. His pioneering research on how climate change disrupts natural systems used long-term studies on wild species. The work he led on how climate change leads to phenological mismatches within food chains has turned his model species, the great tit, into the poster child for climate change impact. His work on wild long-term populations is complemented with studies in aviaries, and by genomic work, among which the sequencing of the great tit genome.

Marcel combines fieldwork, aviary work and molecular techniques in single projects, for instance by using genomic selection to create selection lines for timing of reproduction in great tit, and then use these lines to look at epigenetic regulation of gene expression as well as to measure fitness consequences of timing in the wild. He is managing the four long-term study populations of hole-nesting species that have ran at the NIOO from 1955 onwards.

Marcel has been awarded a NWO-VICI and an ERC Advanced grant, and has been elected as a member of the Royal Netherlands Academy of Sciences (KNAW). He is co-founder and inaugural president of the Netherlands Society for Evolutionary Biology (NLSEB). More info here: https://nioo.knaw.nl/en/employees/marcel-visser.

Ella Cole

Erik Matthysen​​​​​​​Erik is Professor in Evolutionary Ecology at the University of Antwerp, where he teaches courses related to ecology, behaviour, evolution and conservation, as well as ornithology. Hole-nesting birds have been the major study system throughout his career. His first projects were on territoriality and population dynamics in Eurasian Nuthatches, culminating in a PhD in 1988 as well as a monograph published in 1998.

In 1994 he took over the ongoing nestbox study on Great and Blue Tits in Belgium started by André Dhondt, with two main study areas: the Peerdsbos site (running since 1979) and the fragmented Boshoek area (since 1994). These populations have been and are still studied for questions related to dispersal, personality, habitat fragmentation, host-parasite interactions and climate change. The data have been used in many collaborative studies with colleagues all over Europe.

Other bird-related projects in the lab have dealt with conservation, sociality and population dynamics of forest birds in Kenya and Bolivia, and invasion biology of parakeets in Belgium. He has been active in the EOU and IOU as council member and scientific chair of conferences, and has participated in all seven hole-breeding passerine meetings organised since 1985.

PROJECTS THAT USE DATA FROM MULTIPLE BIRD POPULATIONS

1) sTraitChange – How do trait responses to climate change translate into demographic rates and population dynamics?

The project aims at developing a mechanistic framework that improves our ability to predict climate-induced changes across levels of organization, and generalizations of how species with different life-histories respond to climate change.

2) Pair bonds beyond the breeding season

In this project, Dr. Antica Culina uses data on multiple populations of great tit to study causes and consequences of divorce and pair fidelity.

3) EVOCLIM – Phenotypic selection and population demography in fluctuating environments

In this project, Stefan Vriend and Prof. Bernt-Erik Sæther use data on multiple populations of hole-nesting birds to study the role of environmental stochasticity and density dependence in phenotypic selection and population demography across Europe.

4) Why do tits (Paridae) cover their eggs before incubation? The roles of temperature, nest predators and information parasites

Dr. Olli Loukola uses data on multiple tit populations to investigate variation in great and blue tits' egg covering behaviour across different populations in Europe and variables that may explain the geographical variation.

5) Quantifying intra-specific variation in sensitivity to climate change

This project uses sliding window analyses to study how phenological sensitivity to temperature varies among European populations of great and blue tits. The project then seeks to understand how such variation may be driven by differences in the biotic and abiotic environment experienced by each population.

6) Can we use multivariate autoregressive state-space models to quantify species interactions from time series data?

In this project Dr. Emily Simmonds and Prof. Bob O’Hara use Bayesian hierarchical models, including observation error, to try and quantify the strength of competitive interactions. This work predominantly uses simulated data to test model performance, but also uses multiple populations of great tits and blue tits as a case study illustration.

7) Phenotypic variation along urban gradients

Urbanization affects the mean phenotypes of many wildlife populations, but it is not well known how urbanization affects phenotypic variation, a major driver of eco-evolutionary processes. Urbanization can affect phenotypic variation through several processes and can increase the phenotypic variation in urban populations (e.g., urban great and blue tit populations, see here). This project aims to explore how environmental factors associated with urbanization, stress, and heterogeneity impact phenotypic variation along multiple urban gradients across Europe.
