Applied Behavioural and Chemical Ecology of Forest InsectsAssistant Professor – Jeremy Allison

Openings: 2 MScF or PhD, preference for the latter

Description:  Most forest insects use chemical cues and signals to locate resources (e.g., host trees, mates).  As a result, these chemical cues and signals play critical roles mediating host and mate location and have immense potential for use in the development of management tactics for native and invasive forest pests.  I am currently seeking graduate students interested in: (1) the chemical and behavioural ecology of the invasive woodboring beetle the asian longhorned beetle, Anoplophora glabripennis; (2) the orientation and flight behaviour and population ecology of woodboring beetles with the ultimate goal of improving existing monitoring and detection programs for native and invasive woodboring beetles; and (3) the chemical and behavioural ecology of the eruptive forest defoliator the jack pine budworm, Choristoneura pinus pinus.  If you are interested in any of these research projects (or have a project of your own you would like to discuss), please email a copy of your curriculum vitae and a transcript of your grades to me (

Forest fuels and fire behaviour – Professor Mike Wotton

Forest fire managers in Canada (and in numerous countries around the world) evaluate fire potential in their forest environment on a daily basis with outputs from the Canadian Forest Fire Danger Rating System (CFFDRS).  This system includes weather-based models of forest fuel moisture, along with models for fuel type explicit elements of fire behaviour such as a fire’s spread rate and its intensity. Currently the Canadian Forest Service is developing a next generation of many of the models in this system.

Mike Wotton is seeking graduate students to be part of this major effort to develop a new generation of the CFFDRS for both field-based and modelling research projects. Ongoing research projects are related to forest fire behaviour and fire danger rating in general and include fuel moisture prediction, fire ignition and occurrence probability modelling, fuels characterization and rate prediction. Ideal students would have good quantitative skills (e.g., some ability with statistics, computer programming) and some experience working either in the wildfire management community or on field-based research projects.

Statistical analysis of forest fire processes – Professors Dave Martell & Mike Wotton

We have collaborated with several Canadian forest fire management agencies to acquire and refine several large fire, weather and forest composition datasets and we have developed collaborative relationships with statisticians and others to develop and use new statistical methods to model many important fire processes (e.g., daily fire occurrence prediction, spatial and temporal variation in fire activity, the impact of climate change on fire processes).  We are seeking graduate students that wish to become involved in those projects, either in the Firelab at Faculty of Forestry at the University of Toronto or one of the other universities with whom we collaborate.  Practical fire experience would be a definite asset.

Mathematical modelling of forest fire initial attack systems – Professor Dave Martell

Most forest fires are contained at very small sizes but during some days, particularly hot, dry windy days when many fires are reported, the initial attack system can become congested, initial attack can be delayed, and some fires may escape initial attack and become large destructive project fires.  Congested initial attack systems can be modelled as queueing systems with fires as “customers” that wait in the queue until they are “served” by airtankers.  The longer the fires wait the larger and potentially more destructive they become.  Fire mangers need to balance the cost of airtankers with the benefits of shorter response times.  Dave Martell is looking for Masters students with quantitative expertise (e.g., undergraduate courses in mathematics, statistics, geographic information systems and computer programming) and post doctoral researchers (in operations research) that are interested in participating in statistical analysis of initial attack system data and the development and field testing of computer-based queueing models of initial attack systems.  Practical fire fighting or urban emergency response systems experience would be a definite asset.

Fire suppression resource sharing models – Professor Dave Martell

Forest fire management agencies reduce their costs by participating in mutual aid agreements that facilitate the transfer of aircraft, fire fighters and other suppression resources from those that are experiencing low hazard conditions to those that are confronted with large numbers of fires that are being driven by extreme burning conditions.  Dave Martell is seeking Masters students with quantitative expertise (e.g., undergraduate courses in mathematics, statistics, geographic information systems and computer programming) that are interested in participating in the development of strategic planning models that fire managers can use to help determine how they can achieve an appropriate balance between large investments in aircraft and fire fighter hiring and sharing their fire suppression resources with other agencies.

Forest management planning under uncertainty – Professor Dave Martell

Forest managers evaluate strategies and develop plans for planning horizons that span more than 100 years and when they do so, they must account for the possibility that parts of the forests they are managing may be “disturbed” by fire, insects or disease.  Dave Martell is seeking graduate students with quantitative expertise (e.g., undergraduate courses in mathematics, statistics and computer programming) and post doctoral researchers (in forest management or operations research) that wish to develop statistical models of such disturbance process and/or incorporate such models in mathematical programming models of managed forest landscapes. Practical forest management experience would be a definite asset.  For further information contact Dave Martell.

Forest Ecology – Professor Jay R. Malcolm

Research Possibilities (M.Sc. and Ph.D.), Malcolm lab, Faculty of Forestry, University of Toronto, student enrollment 2015-2016

1) Small mammals as seed predators and dispersers

Small mammals have the potential to rearrange the seed shadows of trees through their actions as seed predators and dispersers.  This study will examine variation in small mammal seed predation and caching as a function of seasonal variation in seed supply.  Study will take place on a large forest plot that has been the focus of long-term small mammal trapping and where the tree community has been mapped in unprecedented detail (all stems ≥ 1 cm DBH).

2) Northern flying squirrels as indicators of sustainable forest management practices

Northern flying squirrels are potentially vulnerable to forest management in northern hardwood forests because of their coniferous habitat use and their use of tree cavities as nests.  This study will contrast the behaviour of squirrels in logged and unlogged forests, with a focus on seasonal cavity use.

3) Insect communities of downed wood: thresholds and indicator species

A large proportion of insect species in the boreal forest are saproxylic (i.e., either rely upon dead wood as a habitat resource or rely upon other species that themselves require dead wood).  This research will use an island biogeography framework to investigate the role of dispersal capabilities in structuring the communities of insular communities.  Insects with poor dispersal capabilities and those at high trophic levels (such as parasitoids) are expected to be especially sensitive to reductions of downed wood supplies.  Research will focus upon a series of plots in which dead wood supply was experimentally manipulated to investigate the implications of variation in downed wood supply for species richness and community composition.

4) Tree migration under climate change in Ontario: increasing the potential for migration through strategic increases in habitat connectivity

We have recently undertaken a project modelling the current and future distributions of tree species in Ontario under global warming (134 species, including native species and potential new arrivals from the United States).  Our calculations suggest that the tree migration will greatly influence future forest composition.  This project will examine the potential of land-use conversion to improve upon migration possibilities.  Of particular interest are areas that might be disproportionately important in facilitating such migration (including corridors such as the Niagara Escarpment and the Oak Ridges Morraine).

5) On the sustainability of boreal clearcut logging

This project will make use of high resolution LiDAR and habitat structural information to test the hypothesis that, from a structural habitat perspective, clearcut logging is sustainable in the long term.  Many biological communities are responsive to structural habitat variation; indeed, such variation is a main axis along which one observes niche differentiation.  With the advent of LiDAR technology, which provides detailed information on forest 3-dimensional structure via remote sensing, we are now in a position to evaluate to what extent the habitat structural variation evident in unmanaged forests is emulated by clear cut logging.
