Prediction of mean adult survival rates of southern African birds from demographic and ecological covariates (2014)
Journal Article
Collingham, Y., Huntley, B., Altwegg, R., Barnard, P., Beveridge, O., Gregory, R., …Green, R. (2014). Prediction of mean adult survival rates of southern African birds from demographic and ecological covariates. Ibis: International Journal of Avian Science, 156(4), 741-754. https://doi.org/10.1111/ibi.12195

Estimates of annual survival rates of birds are valuable in a wide range of studies of population ecology and conservation. These include modelling studies to assess the impacts of climatic change or anthropogenic mortality for many species for which...

Social tipping points and Earth systems dynamics (2014)
Journal Article
Bentley, R., Maddison, E., Ranner, P., Bissell, J., Caiado, C., Bhatanacharoen, P., …Garnett, P. (2014). Social tipping points and Earth systems dynamics. Frontiers in Environmental Science, 2, Article 35. https://doi.org/10.3389/fenvs.2014.00035

Recently, Early Warning Signals (EWS) have been developed to predict tipping points in Earth Systems. This discussion highlights the potential to apply EWS to human social and economic systems, which may also undergo similar critical transitions. Soc...

Spatial quantification of leafless canopy structure in a boreal birch forest (2014)
Journal Article
Reid, T., Spencer, M., Huntley, B., Essery, R., Carle, J., Holden, R., …Rutter, N. (2014). Spatial quantification of leafless canopy structure in a boreal birch forest. Agricultural and Forest Meteorology, 188, 1-12. https://doi.org/10.1016/j.agrformet.2013.12.005

Leafless deciduous canopies in boreal regions affect the energy available for snowmelt and reduce overall surface albedo during winter, thereby exerting a strong influence on weather and climate. In this work, ground-based measurements of leafless ca... Read More about Spatial quantification of leafless canopy structure in a boreal birch forest.

Southern Hemisphere temperate tree lines are not climatically depressed (2014)
Journal Article
Cieraad, E., McGlone, M., & Huntley, B. (2014). Southern Hemisphere temperate tree lines are not climatically depressed. Journal of Biogeography, 41(8), 1456-1466. https://doi.org/10.1111/jbi.12308

Aim Southern temperate tree lines are found at low elevations compared with their Northern Hemisphere counterparts. They are also regarded as forming at warm temperatures, which has been attributed to taxon-specific limitations. Using New Zealand tre...

Suborbital climatic variability and centres of biological diversity in the Cape region of southern Africa (2014)
Journal Article
Huntley, B., Midgley, G., Barnard, P., & Valdes, P. (2014). Suborbital climatic variability and centres of biological diversity in the Cape region of southern Africa. Journal of Biogeography, 41(7), 1338-1351. https://doi.org/10.1111/jbi.12288

Aim To explore the magnitude and spatial patterns of last glacial stage orbitally forced climatic changes and suborbital climatic fluctuations in southern Africa, and to evaluate their potential roles in determining present biodiversity patterns. Loc... Read More about Suborbital climatic variability and centres of biological diversity in the Cape region of southern Africa.

Characterising forest gap fraction with terrestrial lidar and photography: An examination of relative limitations (2014)
Journal Article
Hancock, S., Essery, R., Reid, T., Carle, J., Baxter, R., Rutter, N., & Huntley, B. (2014). Characterising forest gap fraction with terrestrial lidar and photography: An examination of relative limitations. Agricultural and Forest Meteorology, 189-190, 105-114. https://doi.org/10.1016/j.agrformet.2014.01.012

Previous studies have shown that terrestrial lidar is capable of characterising forest canopies but suggest that lidar underestimates gap fraction compared to hemispherical camera photography. This paper performs a detailed comparison of lidar to cam... Read More about Characterising forest gap fraction with terrestrial lidar and photography: An examination of relative limitations.

Projecting impacts of anthropogenic climatic change on the bird communities of southern Swedish spruce monocultures: Will the species poor get poorer? (2014)
Journal Article
Felton, A., Lindbladh, M., Elmberg, J., Felton, A., Andersson, E., Sekercioglu, C., …Huntley, B. (2014). Projecting impacts of anthropogenic climatic change on the bird communities of southern Swedish spruce monocultures: Will the species poor get poorer?. Ornis Fennica, 91(1), 1-13

The potential impact of climatic change on bird species’ distributions in Europe was recently modeled for several scenarios of projected late 21st century climate. The results indicate mean range shifts of hundreds of kilometres north for many of Eur...

Biases in Reanalysis Snowfall Found by Comparing the JULES Land Surface Model to GlobSnow (2014)
Journal Article
Hancock, S., Huntley, B., Ellis, R., & Baxter, R. (2014). Biases in Reanalysis Snowfall Found by Comparing the JULES Land Surface Model to GlobSnow. Journal of Climate, 27(2), 624-632. https://doi.org/10.1175/jcli-d-13-00382.1

Snow exerts a strong influence on weather and climate. Accurate representation of snow processes within models is needed to ensure accurate predictions. Snow processes are known to be a weakness of land surface models (LSMs), and studies suggest that...
