About

Professor James D. M. Speed

My research involves a range of taxa from vascular plants and bryophytes to invertebrates, birds and mammalian herbivores. I work at a range of scales, from the individual to the biome, with short term experiments to palaeoecology, and from local scale patterns to regional and biome scale processes. Developing interests are biogeography and ecoinformatics. I have worked in environments from the high-arctic and temperate-alpine regions to boreal forests and African savannahs. I am interested in understanding diversity patterns in terms of species interactions with their environments and evolutionary relationships. A further core interest involves disentangling the interactive impacts of vertebrate herbivory and climate on plant populations and communities and ecosystem ecology.

I am a member of the editorial board for the journals Ecology and Ecological Monographs

I have been a fellow on the NTNU Outstanding Academic Fellows programme and a holder of a Research Council of Norway Young Research Talents project.

Current Research

Disentangling the impacts of herbivory and climate on ecological dynamics: The DISENTAGLE project addresses how climate and herbivory together affect ecosystem processes across spatial scales. The project investigates interactions between herbivory and climate in northern ecosystems by examining (1) The growth of woody plants and community composition at the site scale. (2) The ability of herbivores to determine plant species distributions at a regional scale and (3) The functional and phylogenetic ecology of herbivores across the world's arctic and boreal ecosystems.

CHARTER: Drivers and feedbacks of changes in Arctic terrestrial biodiversity.

ForestPotential Changing Forest Area and Forest Productivity – Climatic and Human Causes, Effects, Monitoring Options, and Climate Mitigation Potential

SustHerb Project The SustHerb project is working towards sustainable management of moose, red deer and their food resources. I am involved in analysing vegetation and tree response to browsing herbivores.

Previous projects

AfricanBioServices: Investigating how productivity, nutrient cycling and carbon storage vary with livestock and wild herbivore grazing along a climatic gradient in the Serengeti-Mara ecosystem

MIRACLE project: Mires and climate: towards enhancing functional resilience of fen peatlands

Sheep Grazing Project Quantification of the impact of grazing on the distribution and growth of mountain birch above the forest line.

Managing ecosystem services in low alpine cultural landscapes through livestock grazing Moving on from this project we are investigating how sheep grazing impacts on alpine ecosystem services through impacts on the treeline.

Systematic review of impacts of reindeer grazing. I was part of a team carrying out a systematic review of the impacts of reindeer herbivory on mountain and arctic vegetation

DYLAN Project Homepage I also worked within the DYLAN project where I am synthesising the impact of land use and natural drivers of landscape state across protected areas in Norway and the UK, with a long-term perspective.
