THEORETICAL CONCEPTS AND EMPIRICAL APPROACHES TO MEASURING INTERACTION STRENGTH
Autor: J. Timothy Wootton, Mark S. Laska
Publikováno v: Ecology. 79:461-476
Evaluating the strength of interactions among species is an important step in understanding the structure of natural communities and predicting how they will respond to changes in the biotic environment. Where feasible, accurate characterization of i

Structure of Understory Shrub Assemblages in Adjacent Secondary and Old Growth Tropical Wet Forests, Costa Rica1
Autor: Mark S. Laska
Publikováno v: Biotropica. 29:29-37
Many studies demonstrating the high species diversity of old growth tropical rain forest plant communities have focused on tree species while neglecting the composition of understory shrubs. This study addresses whether the floristic composition, spe

Metal concentrations in feathers of birds from Papua New Guinea forests: Evidence of pollution
Autor: Mark S. Laska, Joanna Burger, Michael Gochfeld
Publikováno v: Environmental Toxicology and Chemistry. 12:1291-1296
The authors used the feathers of seven species of birds from New Guinea highland forests to examine concentrations of heavy metals and selenium. The authors tested the null hypotheses that there were no species, food type, or elevation differences in

Effects of Fruit Crop Size on Intensity of Fruit Removal in Viburnum prunifolium (Caprifoliaceae)
Autor: Mark S. Laska, Edmund W. Stiles
Publikováno v: Oikos. 69:199
We tested the effect of crop size on fruit removal from an early successional shrub, Viburnum prunifolium (Caprifoliaceae), by comparing the «survival» distributions of fruit from plants with large crops to those with small crops. We found that cro
