Mast seeding and Lyme disease.
We wish to comment on two issues relating to a prediction raised in the article by Randolph1 about our work2. Randolph argues that because ‘low acorn production and moderate mouse densities are the norm [our] data do not explain the cause of the severe acorn failures and contingent crash in mouse populations that might initiate [gypsy] moth outbreaks’. We made no attempt to explain masting peri...
متن کاملOak mast seeding as a direct cause of gypsy moth outbreaks?
In our paper (Liebhold et al. 2000) we reviewed the literature on the dynamics of the gypsy moth (Lymantria dispar L.) populations in North America. This paper highlighted a previously developed hypothesis, namely that gypsy moth outbreaks are caused by decreased rates of predation by small mammal predators as a result of diminished predator populations following years of low mast production by...
متن کاملRAG Recombinase as a Selective Pressure for Genome Evolution
The RAG recombinase is a domesticated transposable element co-opted in jawed vertebrates to drive the process of the so-called V(D)J recombination, which is the hallmark of the adaptive immune system to produce antigen receptors. RAG targets, namely, the Recombination Signal Sequences (RSS), are rather long and degenerated sequences, which highlights the ability of the recombinase to interact w...
متن کاملSnow tussocks, chaos, and the evolution of mast seeding.
One hitherto intractable problem in studying mast seeding (synchronous intermittent heavy flowering by a population of perennial plants) is determining the relative roles of weather, plant reserves, and evolutionary selective pressures such as predator satiation. We parameterize a mechanistic resource-based model for mast seeding in Chionochloa pallens (Poaceae) using a long-term individually s...
متن کاملMechanisms of mast seeding: resources, weather, cues, and selection.
546 I. 546 II. 547 III. 548 IV. 552 V. 554 VI. 556 VII. 558 VIII. 558 IX. 559 559 References 559 SUMMARY: Mast seeding is a widespread and widely studied phenomenon. However, the physiological mechanisms that mediate masting events and link them to weather and plant resources are still debated. Here, we explore how masting is affected by plant resource budgets, fruit maturation success, and hor...
