The reliability of palatability estimates obtained from rumen contents analysis and a field-based index of diet selection

Understanding herbivore foraging behaviour is often limited by not knowing the palatability of food items. Electivity indices can overcome this challenge by relating the consumption of food items to their relative abundance in the environment Tanentzap, A. J.; Bee,  J. N.; Lee, W. G.; Lavers, R.

Landscape-level vegetation recovery from herbivory: progress after four decades of invasive red deer control

Report long-term vegetation changes in permanent plots located in forest, shrubland and grassland communities across a mountain range in southern New Zealand. We test whether 92% reduction in the population of invasive non-indigenous red deer, Cervus elaphus, since 1964 has led to the recovery of deer-preferred species. Tanentzap, A.J.; Burrows, L.E.; Lee, W.G.; Nugent, G; … Continue reading Landscape-level vegetation recovery from herbivory: progress after four decades of invasive red deer control

Mapping community change in modified landscapes

We convert point observations of more than 28,000 beetles from 851 species into a continuous biodiversity surface representing the similarity of ecological communities relative to that of pristine forest, effectively integrating on-the-ground biodiversity data with remotely sensed landcover data to predict the magnitude of community change in a modified landscape. Ewers, R.M.; Kapos, V.; Coomes, … Continue reading Mapping community change in modified landscapes

Size-dependence of growth and mortality influence the shade tolerance of trees in a lowland temperate rain forest

Quantification of growth and mortality for two different juvenile life stages – seedlings and saplings– of seven tree species common in temperate rain forests in New Zealand using data from field studies. Strong evidence that the ranking of species for survival in shade and growth in full light was affected by size. Kunstler, G.; Coomes, … Continue reading Size-dependence of growth and mortality influence the shade tolerance of trees in a lowland temperate rain forest

Impacts of introduced deer and extinct moa on New Zealand ecosystems

An attempt to describe and compare the impacts of the invasive red deer in New Zealand with the extinct species of Moa, large flightless birds, which appeared to occupy significantly overlapping habitat niches to present day deer. Forsyth, D.M.; Wilmshurst, J.M.; Allen, R.B.; Coomes, D.A. 2009 PDF

A greater range of shade-tolerance niches in nutrient-rich forests: an explanation for positive richness–productivity relationships?

Investigating if a wider range of growth rates and shade tolerances are found on nutrient-rich soils, because such soils not only support fast-growing species with high metabolic rates, but also species capable of tolerating the very deep shade cast by forest canopies growing where nutrients are plentiful. Coomes, D.A.; Kunstler, G.; Canham, C.D.; Wright, E. … Continue reading A greater range of shade-tolerance niches in nutrient-rich forests: an explanation for positive richness–productivity relationships?

The benefits of being in a bad neighbourhood: plant community composition influences red deer foraging decisions

The role of neighbour palatability in affecting foraging of a target plant by large mammalian herbivores using a large-scale field dataset on diet selection by red deer. Examining whether intraspecific variation in browsing of plants can be related to variation in the local abundance of alternative forage species. Bee, J.N.; Tanentzap, A.J.; Lee, W.G.; Lavers, … Continue reading The benefits of being in a bad neighbourhood: plant community composition influences red deer foraging decisions

Spatially explicit models to analyze forest loss and fragmentation between 1976 and 2020 in southern Chile

Identification of the geophysical variables (“pattern drivers”) that explain the spatial patterns of forest loss and fragmentation between 1976 and 1999 using both a GIS-based land-use change model (GEOMOD) and spatially explicit logistic regression. Includes projections where and how much forest fragmentation will occur in the future by extrapolation of the current rate of deforestation … Continue reading Spatially explicit models to analyze forest loss and fragmentation between 1976 and 2020 in southern Chile
