Food Production and the Energy Crisis
- D. Pimentel, L. E. Hurd, +4 authors R. J. Whitman
- Business, Medicine
- Science
- 2 November 1973
The principal raw material of modern U.S. agriculture is fossil fuel, whereas the labor input is relatively small (about 9 hours per crop acre). As agriculture is dependent upon fossil energy, crop… Expand
An ecological study of a natural population of diamondback terrapins (Malaclemys t. terrapin) in a Delaware salt marsh
- L. E. Hurd, G. Smedes, T. Dean
- Biology
- 1 March 1979
A two-year study of a population of the northernediamondback terrapin (Malaclemys t. terrapin) was undertaken in a salt marsh in Delaware. Population size estimates based on markrelease-recapture… Expand
Development in an estuarine fouling community: The influence of early colonists on later arrivals
- T. Dean, L. E. Hurd
- Biology, Medicine
- Oecologia
- 1 September 1980
SummaryExperiments were performed to determine if earlier colonists inhibited, enhanced, or were necessary for establishment of later colonists during development of an estuarine fouling community at… Expand
Hatch Density Variation of a Generalist Arthropod Predator: Population Consequenes and Community Impact
- W. Fagan, L. E. Hurd
- Biology
- 1 October 1994
We examined density dependence in population attributes and community impact of a generalist predator by experimentally mimicking natural variation in initial cohort densities produced by synchronous… Expand
Top-down cascade from a bitrophic predator in an old-field community
- M. Moran, T. Rooney, L. E. Hurd
- Biology
- 1 October 1996
We tested the hypothesis that a bitrophic (third and fourth level) arthropod predator can exert a cascading, top—down influence on other arthropods and plants in an early successional old field.… Expand
Experimental density manipulations of the predator Tenodera, sinensis (Orthoptera: Mantidae) in an old-field community. I: Mortality, development and dispersal of juvenile mantids
- L. E. Hurd, R. Eisenberg
- Biology
- 1 February 1984
(1) Field and laboratory experiments were carried out to examine the effects of density on early life-history characteristics of the mantid, Tenodera sinensis. (2) For three replicated field… Expand

- Biology
- 1999
Ancient, medieval and early modern writings about mantids - shaping contemporary questions taxonomy population and community ecology the ecology and foraging strategy of Tenodera angustipennis mating… Expand
First Identification of a Putative Sex Pheromone in a Praying Mantid
- L. E. Hurd, F. R. Prete, T. Jones, T. B. Singh, J. Co, Richard T. Portman
- Biology, Medicine
- Journal of Chemical Ecology
- 2004
Praying mantids are models for a wide variety of behavioral, physiological, and ecological studies, and sex pheromones have been assumed to be important components of their biology. However, no… Expand
Disturbance, coral reef communities, and changing ecological paradigms
- R. Karlson, L. E. Hurd
- Biology
- Coral Reefs
- 1 November 1993
We examine changing ecological theory regarding the role of disturbance in natural communities and relate past and emerging paradigms to coral reefs. We explore the elements of this theory, including… Expand
Stability and Diversity at Three Trophic Levels in Terrestrial Successional Ecosystems
- L. E. Hurd, M. Mellinger, L. L. Wolf, S. J. McNaughton
- Biology, Medicine
- Science
- 17 September 1971
An ecosystem perturbation experiment in which inorganic fertilizer was added to two successional old fields of different ages indicated that stability, expressed as resistance to modification by… Expand
