“…The ever present, but moderate damage in Australia was frequently interspersed with serious to very severe outbreaks. The latest of these occurred in the Green Triangle (south-eastern South Australia and south-western Victoria) between 1987 and 1990, despite an established control programme ( Haugen, 1990 ). This was primarily due to the absence of monitoring of the S. noctilio population, a neglected biological control programme, and overstocked stands ( Haugen, 1990 ).…”

“…Despite considerable investment in research, the steady spread and occasional serious outbreaks of S. noctilio were not completely curtailed in Australia ( Neumann et al , 1987;Madden, 1988;Haugen, 1990 ). The ever present, but moderate damage in Australia was frequently interspersed with serious to very severe outbreaks.…”

1 Sirex noctilio has resulted in one of the most damaging biological invasions of pine forestry in the southern hemisphere. 2 An intensive, integrated control programme has been developed for this pest and is generally considered very successful. However, a critical comparison of S. noctilio infestations and control efforts throughout the southern hemisphere reveals that control has not been uniformly effective. Of particular concern is the apparently unexplained variability in establishment and success of biological control agents, including various parasitic wasps and the parasitic nematode Deladenus siricidicola . 3 An overlooked aspect in the establishment of the biological control interventions for S. noctilio is the potential influence of genetic bottlenecks on the ability of the agents to adapt to different environments and different populations of S. noctilio . 4 Despite established biological control agents, stress in forests caused by silvicultural practices or the environment will predispose trees to heavy infestation. Unfortunately, improved silvicultural practices are not always economically feasible and environmental changes are often unavoidable. 5 Sirex noctilio continues to pose a serious threat to pine forestry in many areas.Despite extensive earlier research into a single integrated control for S. noctilio , it is important to recognize that such a strategy will probably require significant local adaptation in new areas of infestation and over time.

“…This species has rarely been viewed as a serious threat to forests or plantations of pine in its region of origin. In contrast, S. noctilio has caused serious damage to pine plantations in the southern hemisphere where it has been accidentally introduced several times (Neumann and Minko 1981;Haugen 1990;Hurley et al 2007). In the Southern Hemisphere, up to 80% mortality has been recorded in outbreaks in plantations.…”

“…For example, in Australia, extensive inoculation programs in the 1980 s eventually failed when the nematode lost its virulence (Haugen 1990, Haugen andUnderdown 1993). The loss of virulence was resolved by introducing a newly isolated strain, Kamona, from Tasmania (Bedding and Iede 2005).…”

“…In the Southern Hemisphere, up to 80% mortality has been recorded in outbreaks in plantations. The difference in the impact of this insect in areas of introduction compared to in its native range has been attributed to the absence of, or irregular pressure from, natural enemies, the presence of large stands of susceptible hosts that are uniform in age and genetic composition, and wide-scale stress in host trees (either due to poor management, dense planting practices, or natural environmental factors such as drought) (Neumann and Minko 1981;Haugen 1990;Hurley et al 2007).…”

Anthropogenic effects on interaction outcomes: examples from insect-microbial symbioses in forest and savanna ecosystems

et al. 2011

The influence of humans on ecosystem dynamics has been, and continues to be, profound. Anthropogenic effects are expected to amplify as human populations continue to increase. Concern over these effects has given rise to a large number of studies focusing on impacts of human activities on individual species or on biotic community structure and composition. Lacking are studies on interactions, particularly mutualisms. Because of the role of mutualisms in ecosystem stability, such studies are critically needed if we are to begin to better understand and predict the responses of ecosystems to anthropogenic change. Most organisms are involved in at least one mutualism, and many in several. Mutualisms facilitate the ability of partners to exploit particular habitats and resources, and play a large role in determining ecological boundaries. When change disrupts, enhances, or introduces new organisms into a mutualism, the outcome and stability of the original partnership(s) is altered as are effects of the symbiosis on the community and ecosystem as a whole. In this paper, using examples from six microbe-insect mutualisms in forest and savanna settings, we showcase how varied and complex the responses of mutualisms can be to an equally varied set of anthropogenic influences. We also show how alterations of mutualisms may ramify throughout affected systems. We stress that researchers must be cognizant that many observed changes in the behaviors, abundances, and distributions of organisms due to human activities are likely to be mediated by mutualists which may alter predictions and actual outcomes in significant ways.
