Internship - Reproductive characteristics of the great tit in contrasting environments

Internship -  Reproductive characteristics of the great tit in contrasting environments

Netherlands Institute of Ecology, Netherlands

 

Climate change is one of the major threats to biodiversity and has major impacts on species’ life history traits (traits having a clear effect on fitness) like for example growth and reproduction. Previous research has shown that increasing temperatures advanced the lay date of the great tit in the wild. But what is the effect of warmer temperatures on characteristics such as egg and/or clutch size?

In the wild the great tit lays clutches of 5-12 eggs and it is thought that egg size and the amount of resources in the egg are actively regulated by the female and also depends on food intake. Larger eggs are in favor of fitness of the offspring; their hatching success and fledgling survival. We have great tits in climate controlled aviaries being subjected to contrasting environments (warm and cold). Thus an ideal set-up to test whether temperature has an effect on egg size without resource constraints.

The project consists of two parts; first monitoring the aviaries during the breeding season where you will collect data and second analyze the collected data together with already collected data from 2015 and 2016. This project is a nice opportunity to get affiliated with birds held in captivity and analyze data collected by yourself from these birds. The start of the project is preferably from half March onwards. The end date is open and depends also on the student.
