“…Empirical studies of spatial synchrony have generally found that the correlation decays with distance (Myers and Rothman 1995;Steen et al 1996;Sutcliffe et al 1996;Ranta et al 1997;Bjørnstad et al 1999). Ecological theory (as developed here and elsewhere; e.g., Tilman and Kareiva 1997;Bascompte and Solé 1998) shows that both dispersal and extrinsic factors (via the Moran effect) can synchronize populations.…”

“…Regional synchrony in the dynamics of local populations is common in animal populations ranging from parasites (Bolker and Grenfell 1996) to insects (Pollard 1991;Hanski and Woiwod 1993;Myers and Rothman 1995;Williams and Liebhold 1995;Sutcliffe et al 1996Sutcliffe et al , 1997, fish (Myers et al , 1997, birds (Ranta et al 1995;Koenig 1998), and mammals (Moran 1953;Mackin-Rogalska and Nabaglo 1990;Steen et al 1990;Royama 1992;Sinclair et al 1993;Heikkila et al 1994;Grenfell et al 1998;Bjørnstad et al 1999). The classical explanation for this phenomenon is that regionally correlated climatic forces engender population synchronization (Hagen 1952;Mackenzie 1952;Moran 1953), a hypothesis that has been reinvestigated in several recent theoretical studies (Royama 1992;Ranta et al 1995;Haydon and Steen 1997).…”

“…Many aspects of the design of nature reserves and the effective conservation of endangered species thus hinge on the level of regional synchronization in species dynamics. The resilience of populations to manipulation (Myers and Rothman 1995), to biological control (Cavalieri and Kocak 1995), and to pest eradication (Bolker and Grenfell 1996) can also be related to the degree of correlation in dynamics.…”

“…Experimental approaches are also commonly used to study the processes influencing insect outbreak cycles (Myers and Rothman 1995). The scope and complexity of such experiments can vary significantly, ranging from fairly targeted studies assessing relationships among herbivores, host plants, and natural enemies, to more complex field experiments where the researchers have sought to manipulate outbreak cycles through preventing outbreaks, creating outbreaks, or manipulating the processes hypothesised to drive changes in population density (reviewed in Myers and Rothman 1995). In some cases, the theoretical advancements derived from experiments have been profound.…”

Abstract-Our review highlights research during the past century focussed on the population ecology of outbreak-prone insect defoliators in Canadian forests. Based on reports from national and provincial surveys that began in the 1930s, there have been at least 106 insect defoliators reported to outbreak, most of which are native Lepidoptera, Hymenoptera (sawflies), or Coleoptera (in order of frequency from most to least). Studies comparing life-history traits of outbreak versus non-outbreak species to better understand why certain species are more outbreak-prone indicate several traits especially common among outbreak species, including egg clustering and aggregative larval feeding. There have been at least 50 time-series studies examining the spatiotemporal population behaviour of 12 major defoliator species. These studies provide evidence for both regular periodicity and spatial synchrony of outbreaks for most major species. Life-table studies seeking to understand the agents causing populations to fluctuate have been carried out for at least seven outbreak species, with the majority identifying natural enemies (usually parasitoids) as the major driver of outbreak collapse. Our review concludes with several case studies highlighting the impact and historical underpinnings of population studies for major defoliator species and a discussion of potential avenues for future research.

“…Algal blooms like the Chrysochromulina polylepis bloom of 1988 along the Norwegian Skagerrak coast may be considered natural experiments (Myers & Rothman 1995, Underwood 1996. Interpreting the dynamical effects, both on a shorter and longer time-scale, is important in our efforts to try to understand the dynamic interactions within these communities (Underwood 1989(Underwood , 1996.…”

The long-term effects of the 1988 algal bloom (Chrysochromulina polylepis Manton et Parke) along the Norwegian Skagerrak coast are evaluated and discussed on the basis of several monitoring programmes. Effects on individual growth and survival of coastal cod and its population dynamics are analysed. Cod suffered a high mortality from June until November, and the 1988 yearclass was strongly reduced. Growth was only slightly affected. Furthermore, the effects at the community level are evaluated for the coastal fish community and the benthic communities. These communities were strongly affected on a short time scale, but recovered surprisingly fast. Populations of most organisms had recovered within months, and after 1 yr few traces of the toxic bloom could be observed; after 4 to 5 yr all communities had essentially recovered. As part of the review we also discuss to what extent harmful blooms are likely to reoccur, and conclude that blooms have reoccurred and will continue to do so. However, nothing can be concluded about the toxicity of such blooms. We expect that even large perturbations are unlikely to leave any profound long-lasting effects. The effects of the 1988 bloom are discussed within a theoretical framework including stability, resilience and inertia. In conclusion we emphasise the importance of long-term monitoring data; without such data the analyses reported in this paper would have been impossible.
