Toward conservation of Canada's boreal forest avifauna: Design and application of ecological models at continental extents
Download2010
Cumming, S. G., Bayne, E., Schmiegelow, F. K. A., Fontaine, T., Song, S. J., Lefevre, K.
Abstract: Human development is increasing pressure on North America's mainly intact boreal forest. We outline the need for a comprehensive synthesis of existing data and for effective scientific tools to support conservation of this biome and of the birds that depend on it. To illustrate how...

Wasylishen, R. E., Bernard, G. M., Quideau, S. A., Norris, C. E., Landhausser, S. M.
Abstract: Enriching plant tissues with C-13 and N-15 isotopes has provided long-lasting, non-reactive tracers to quantify rates of terrestrial elemental fluxes (e.g., soil organic matter decomposition). However, the molecular location and level of isotope enrichment may differ among plant...

Smith, K.G., Schmiegelow, F., McDermid, G.J., Bradley, M., Hervieux, D., Hebblewhite, M., Musiani, M., Whittington, J., Wheatley, M., Neufeld, L., Decesare, N.J., Morgantini, L.E.
Multi-scale resource selection modeling is used to identify factors that limit species distributions across scales of space and time. This multi-scale nature of habitat suitability complicates the translation of inferences to single, spatial depictions of habitat required for conservation of...

Trees Wanted - dead or alive! Host selection and population dynamics in tree-killing bark beetles
Download2011
Erbilgin, N., Gregoire, J. C., Gilbert, M., Kausrud, K. L., Skarpaas, O., Stenseth, N. C., Okland, B.
Abstract: Bark beetles (Coleoptera: Curculionidae, Scolytinae) feed and breed in dead or severely weakened host trees. When their population densities are high, some species aggregate on healthy host trees so that their defences may be exhausted and the inner bark successfully colonized, killing...

Tropical forest restoration within Galapagos National Park: application of a state-transition model
Download2005
Wilkinson, S.R., Schmeigelow, F.K.A., Naeth, M.A.
Current theory on non-equilibrium communities, thresholds of irreversibility, and ecological resilience suggests the goal of ecological restoration of degraded communities is not to achieve one target, but to reestablish the temporal and spatial diversity inherent in natural ecosystems. Few...

Sikkema, E.H., Field, T., Pittermann, J., Sano, Y., Sperry, J.S., Hacke, U.G.
Two structure-function hypotheses were tested for vesselless angiosperm wood. First, vesselless angiosperm wood should have much higher flow resistance than conifer wood because angiosperm tracheids lack low-resistance torus-margo pits. Second, vesselless wood ought to be exceptionally safe from...

Weak tradeoff between xylem safety and xylemspecific hydraulic efficiency across the world’s woody plant species

Maherali, H., Cao, K-.F., Schreiber, S.G., Brodribb, T.J., Westoby, M., Hacke, U.G., Jacobsen, A.L., Lens, F., Choat, B., Wright, I.J., Pittermann, J., Gleason, S., Bhaskar, R., Nardini, A., Morris, H., Mayr, S., Bucci, S.J., Mencuccini, M., Johnson, D.M., Mitchell, P.J., Fan, Z-.X., Sperry, J.S., Delzon, S., Zanne, A.E., Martínez-Vilalta, J., Cochard, H., Plavcová, L., McCulloh, K.A., Jansen, S., Domec, J-.C., Pratt, R.B., Feild, T.S.
The evolution of lignified xylem allowed for the efficient transport of water under tension, but also exposed the vascular network to the risk of gas emboli and the spread of gas between xylem conduits, thus impeding sap transport to the leaves. A well-known hypothesis proposes that the safety of...
