Map of predicted pest swarming date

The primary goal of this project is to provide a practical visual tool that communicates scientific evidence to stakeholders involved in Ireland's plant biosecurity policy and pest/pathogen-risk management.

Adaptation, mitigation and protection strategies to increase resilience of Irish forests to address the impacts of climate change

People: Two PhD students, One postdoc, Marialaura Destefanis (DAFM), Amanda Brechon (DAFM), Annmarie Hamilton (Coillte), Archie Murchie (AFBI), Niall Farrelly (Teagasc) Conor McGee (DAFM), Richard O'Hanlon (DAFM), Jon Yearsley (UCD)

Irish Scot's Pine Stand of trees This research is pillar 3 of the project entitled "Adaptation, mitigation and protection strategies to increase resilience of Irish forests to address the impacts of climate change (ADAPTForRes)". This project will develop optimised surveillance tools for the early detection of fungal forest pests in Ireland.

SUSPOLL: Sustainable pollination services in a changing world

People: Sarah MacQueen, Arrian Karbassioon, Alison O'Reilly , Jon Yearsley Dara Stanley (lead PI),

Bumblebee This project the response of pollination services to pesticides and climate change. The modelling component of the project looks at the thermodynamics of pollinators as a mechanistic model of pollinator activity.

Past Research Projects

Modelling the impact and management of marine invasive species (MIMMIS)

People: Morane Clavel-Henry, Rebecca Giesler, Tasman Crowe, Jon Yearsley

Pacific oysters This project studies the spread of two target marine invasive species along Ireland's coastline. The project is a combination of larval biophysical modelling and the marine ecology of invasive species.

The phenology of perennial ryegrass and its potential contribution to grassland carbon sequestration

People: Carl Fisk, Rainer Melzer, Hannah White, Charilaos Yiotis, Jon Yearsley

Ryegrass in a growth chamber This project studies the phenology of perenial rye grass pastures in Ireland (primarily the length of the growing season) and the variation in phenology between different varieties of rye grass. Increasing the growing season of perennial rye grass pasture has the potential to increase the ability of Irish grasslands to sequester carbon.

Biodiversity, resilience and food security: understanding the role of biodiversity in maintaining food production

People: Maja Ilić, Amy Arnott, Willson Gaul, Mark Emmerson, Paul Caplat, Tim Benton, Jon Yearsley

Irish grassland This project studies the resilience of grassland production systems and their capacity to resist, recover and adapt to future environmental change, whilst sustainably producing food for a growing global population.

Deep-sea larval dispersal and ecosystem connectivity

People: Julia Sigwart, Cindy van Dover, Jens Carlsson, Jon Yearsley

Deep-sea simulated dispersal What is the dispersal capacity of marine larvae in the deep-sea? How are deep-sea ecosystems colonised and from where? We are using oceanographic and genetic data to address such questions.

Population Genetics of Collective Dispersal

People: Thomas Broquet, Frederique Viard, Glenn Yannic, Jon Yearsley

dog whelk We are developing population genetic theory that describes collective dispersal, where multiple individuals show similar dispersal pathways. This type of dispersal is seen for marine invertebrate larvae, wind dispersed organisms, and is also applicable to dispersal at a species' range margin.

Range Expansion of the Greater White-Toothed Shrew in Ireland

People: Allan McDevitt, Jon Yearsley

Small mammal trapping The greater white-toothed shrew (Crocidura russula) was first discovered in Ireland in 2007. Ever since it has been gradually expanding its distribution. The study uses the greater white-toothed shrew as a model species to study evolutionary processes at an expaning range margin. We are also collaborating with colleagues in Queen's University Belfast (Ian Montgomery, Neil Reid, David Tosh) to quantify the rate at which this shrew is spreading across Ireland and its ecological impact.
