Integrated pest management and allocation of control efforts for vector-borne diseases
H. S. Ginsberg
2001, Journal of Vector Ecology (26) 32-38
Applications of various control methods were evaluated to determine how to integrate methods so as to minimize the number of human cases of vector-borne diseases. These diseases can be controlled by lowering the number of vector-human contacts (e.g., by pesticide applications or use of repellents), or by lowering the...
Attractor reconstruction for non-linear systems: a methodological note
J.M. Nichols, J.D. Nichols
2001, Mathematical Biosciences (171) 21-32
Attractor reconstruction is an important step in the process of making predictions for non-linear time-series and in the computation of certain invariant quantities used to characterize the dynamics of such series. The utility of computed predictions and invariant quantities is dependent on the accuracy of attractor reconstruction, which in...

Although the poaching of nestlings for the pet trade is thought to contribute to the decline of many species of parrots, its effects have been poorly demonstrated. We calculated rates of mortality due to nest poaching in 23 studies of Neotropical parrots, representing 4024 nesting attempts in 21 species and...
Flow and habitat effects on juvenile fish abundance in natural and altered flow regimes
Mary C. Freeman, Z.H. Bowen, K.D. Bovee, E.R. Irwin
2001, Ecological Applications (11) 179-190
Conserving biological resources native to large river systems increasingly depends on how flow-regulated segments of these rivers are managed. Improving management will require a better understanding of linkages between river biota and temporal variability of flow and instream habitat. However, few studies have quantified responses of native fish...
