The phenology of perennial ryegrass and its potential contribution to grassland carbon sequestration
Join the team! We're hiring
8 month post-doctoral fellowship (Job Reference Number 012728)
We are seeking a post-doctoral fellow for research on the phenology of perennial ryegrass pastures, with a primary focus on the timing of the start (green-up) and end (senescence) of the growing season. This postdoctoral fellow will be part of an EPA funded project that aims to evaluate variations in the phenology of perennial ryegrass.
The post-doctoral fellow will have good skills in quantitative ecology. They will be responsible for the statistical analysis of experimental data from plant growth chamber experiments and the analysis of remote-sensing satellite data (primarily MODIS) to study the phenology of improved grasslandsacross Ireland. The post-doctoral fellow will also contribute to a new growth chamber experiment in collaboration with other project members
Deadline extended: Apply before 5pm 19th November.

In the face of climate change and under growing pressure to reduce greenhouse gas emissions, phenology - the timing of developmental events in a plant life cycle - is strongly dependent on environmental and genetic conditions. Phenological events will change if temperatures increase, and this poses largely uncharacterized challenges and opportunities for Irish ecosystems.
This project aims to evaluate the significance of variations in the phenology of perennial ryegrass. Perennial ryegrass is economically and ecologically the most important species of improved grasslands in Ireland. These grasslands are important carbon sinks and thus the phenological response to climate can be an important factor underpinning any reductions in greenhouse gas emissions
We will combine remote sensing, the analysis of historical data, and experimental measurements under current and future climatic conditions to obtain a holistic view of the phenology of perennial ryegrass. Using this data, modelling will be employed to determine the phenological response of different perennial ryegrass varieties to changing climatic conditions.
We will use this information to identify perennial ryegrass varieties that are best suited as carbon sinks in a changing environment.
