We developed a spatially-explicit simulation model for the red-cockaded woodpecker, Picoides borealis, an endangered and territorial cooperative breeder endemic to the southeastern United States. This kind of model is especially appropriate for this species because it can incorporate the spatial constraints on dispersal of helpers, and because territory locations are predictable. The model combines demographic data from a long-term study with a description of the spatial location of territories. Sensitivity analysis of demographic parameters revealed that population stability was most sensitive to changes in female breeder mortality, mortality of female dispersers and the number of fledglings produced per brood. Population behavior was insensitive to initial stage distribution; reducing the initial number of birds by one-half had a negligible effect. Most importantly, we found that the spatial distribution of territories had as strong an effect on response to demographic stochasticity as territory number. Populations were stable when territories were highly aggregated, with as few as 49 territories. When territories were highly dispersed, more than 169 territories were required to achieve stability. Model results indicate the importance of considering the spatial distribution of territories in management plans, and suggest that this approach is worthy of further development.}, number={1}, journal={BIOLOGICAL CONSERVATION}, author={Letcher, BH and Priddy, JA and Walters, JR and Crowder, LB}, year={1998}, month={Oct}, pages={1–14} } @article{letcher_rice_crowder_binkowski_1997, title={Size- and species dependent variability in consumption and growth rates of larvae and juveniles of three freshwater fishes}, volume={54}, ISSN={["0706-652X"]}, DOI={10.1139/cjfas-54-2-405}, number={2}, journal={CANADIAN JOURNAL OF FISHERIES AND AQUATIC SCIENCES}, author={Letcher, BH and Rice, JA and Crowder, LB and Binkowski, FP}, year={1997}, month={Feb}, pages={405–414} } @article{letcher_rice_crowder_binkowski_1996, title={Size-dependent effects of continuous and intermittent feeding on starvation time and mass loss in starving yellow perch larvae and juveniles}, volume={125}, ISSN={["1548-8659"]}, DOI={10.1577/1548-8659(1996)125<0014:SDEOCA>2.3.CO;2}, abstractNote={Abstract Starvation rates of fish larvae living in patchy prey environments can have an important impact on cohort survival and recruitment. Despite this, little is known about how fluctuations in feeding experience influence starvation resistance and how this changes with ontogeny. Fish previously exposed to fluctuating food densities may not respond to long periods without food in the same way as fish previously exposed to a constant prey density. In a series of laboratory experiments with larvae and juveniles of yellow perch Perca flavescens, we tested the effects of continuous and intermittent feeding on times to starvation and on mass loss up to death from starvation for fish with initial total lengths of 10, 15, and 20 mm. Results indicated that proportional mass loss up to starvation was independent of fish mass, but that it did depend on feeding history. Fish that fed continuously before starvation all died after losing the same proportion of body mass (55%), but intermittent feeders died when the...}, number={1}, journal={TRANSACTIONS OF THE AMERICAN FISHERIES SOCIETY}, author={Letcher, BH and Rice, JA and Crowder, LB and Binkowski, FP}, year={1996}, month={Jan}, pages={14–26} }
