Out Of The Quagmire Of Plant Defense Hypotheses
  • N. Stamp
  • Medicine, Biology
    The Quarterly Review of Biology
  • 1 March 2003
Several hypotheses, mainly Optimal Defense (OD), Carbon:Nutrient Balance (CNB), Growth Rate (GR), and Growth‐Differentiation Balance (GDB), have individually served as frameworks for investigating
Egg Deposition Patterns in Butterflies: Why Do Some Species Cluster Their Eggs Rather Than Deposit Them Singly?
  • N. Stamp
  • Biology
    The American Naturalist
  • 1 March 1980
TLDR
It is suggested that the occurrence of butterfly species which deposit eggs in clusters is more common than the literature indicates and that data on egg deposition patterns in natural populations of nymphalids in North America, in particular for Phyciodes, Chlosyne, Euphydryas, and Nymphalis species, would support this conclusion.
Caterpillars : ecological and evolutionary constraints on foraging
TLDR
This chapter discusses the constraints on foraging patterns of caterpillars and the consequences of evolutionary and ecological consequences, as well as adaptations reflecting sets of constraints.
EFFECTS OF PLANT AGE, GENOTYPE, AND HERBIVORY ON PLANTAGO PERFORMANCE AND CHEMISTRY'
TLDR
In an experimental garden at Binghamton, New York, the effects of plant age, plant genotype, and herbivory by generalist or specialist caterpillars on Plantago lanceolata showed that herbvory had little effect on plant performance, and there was no difference by the specialist Junonia coenia Hibner (Nymphalidae), compared to the generalist Spilosoma congrua Wlk.
Early stage of host range expansion by a specialist herbivore, Euphydryas phaeton (Nymphalidae)
TLDR
The shift of some populations of E. phaeton onto plantain is most likely a function of several ecological factors rather than genetic differentiation between populations using turtlehead and plantain.
Can the growth–differentiation balance hypothesis be tested rigorously?
  • N. Stamp
  • Computer Science
  • 1 November 2004
TLDR
The growth-differentiation balance (GDB) hypothesis provides a framework for examining the impact of a resource gradient on the constant tradeoff between growth and differentiation in cells and tissues of plants, in particular with the consequences for plant defense.
Self-burial behaviour of Erodium cicutarium seeds.
TLDR
The self-planting mechanism of the hygroscopic 'seeds' of Erodium cicutarium was examined and it was found that seeds with intact awns and carpels attained greater depths than that of those without these structures.
VARIATION IN FOOD QUALITY AND TEMPERATURE CONSTRAIN FORAGING OF GREGARIOUS CATERPILLARS
TLDR
In the absence of predators, in which case larvae eat new leaves, bask, and remain aggregated, the larvae can grow twice as fast and attain more biomass per instar than solitary larvae eating mature leaves in the shade, which is often the case when they avoid predators.
Genetics, behavior and ecology of a paper wasp invasion : Polistes dominulus in North America
TLDR
A review of this ongoing invasion of the European paper wasp Polistes dominulus into North America in terms of population genetic variation in P. dominulus, and data from comparative studies where the two species are sympatric and possible mechanisms contributing to the differences between them is reviewed.
Factors affecting calculation of nutritional induces for foliage‐fed insects: an experimental approach
TLDR
The age of leaves (new versus mature) significantly affected their metabolism and water loss, but simulated herbivory did not directly affect leaf metabolism, and deliberate manipulation of larvae during the course of an experiment significantly reduced relative growth rates.
