“…These indices are useful as they collapse multiple aspects of the physical environment, including ocean currents and air and water temperature, wave height, salinity, wind, and rainfall into a single parameter, and are thus generalizable ''phenomena'' rather than definable changes in single environmental variables (Stenseth et al 2002, Hallett et al 2004, Zhang et al 2007. Moreover, these studies have shown that such large-scale indices can serve as more effective indicators of ecological response than individual weather parameters collected at the scale of the organism (Stenseth 2007).…”

Abstract. Studies of the impacts of climate and climate change on biological systems often attempt to correlate ecological responses with basin-scale indices such as the North Atlantic Oscillation (NAO). However, such correlations, while useful for detecting long-term trends, are unable to provide a mechanism linking the physical environment and ecological processes. Here we evaluate the effects of the NAO on recruitment variability of rocky intertidal invertebrates in the North Atlantic examining two possible climate-related pathways. Using a highly conservative test we interpret associations with the NAO integrated over a season (three months) as an indicator of atmospheric effects on newly settled recruits (NAO3), and the effects of the NAO integrated over six months (NAO6) as an indicator of changes in ocean circulation affecting patterns of larval transport. Through an extensive literature survey we found 13 time series, restricted to southwest Ireland and Britain and comprising five species, that could be used for statistical analysis. Significant correlations with NAO3, our proxy for atmospheric effects, were observed in the south-central domain of our study region (southwest Ireland and south England). Significant correlations with NAO6, the proxy for ocean circulation effects, were detected on southwest Ireland. The associations were detected for three (two barnacles and a topshell) at two sites. These results suggest that the NAO can have effects on the recruitment of intertidal invertebrates through different pathways linked to climate and be distributed heterogeneously in space. Based on previous evidence and the sign and geographic location of significant correlations, we suggest that winter NAO effects are likely to occur as a result of effects on the survival of early life stages settling during spring or through changes in phenology. Our results argue that a combination of modeling and synthesis can be used to generate hypotheses regarding the effects of climate on recruitment and aid in the design of field-based tests of explicit ecological mechanisms.

“…Stenseth et al 2004b). Zhang et al (2007) extend these studies by showing that another prominent climate pattern, the El Niño Southern Oscillation (ENSO), also plays a key role in the dynamics of the hare-lynx system. By so doing, they suggest that the structuring of the ecological dynamics might be more complicated than originally envisioned by Stenseth et al (1999), who suggested that regional differences in climate driven by the NAO resulted in a geographic grouping of lynx population dynamics.…”

“…It is currently known that the hare resources growth model (in this case, a plant) has to be included in the system. Keith (1974), created the plant-hare-lynx hypothesis but the cycle determinants are still under study (Krebs et al, 2001, Zhang et al 2007.…”

Several lines of evidence suggest that the effects of stressors on populations can be calculated accurately by population modeling. Using monitoring data of natural population, population models were applied and the possibility of establishing environmental diagnoses from strictly ecological concepts is discussed. A procedure is offered for the modeling of natural population data and the establishment of population endpoints.Key words: Ecotoxicology. Population Models. Hurst Exponent. Time series analysis. Abordagem populacional em ecotoxicologia (Ecologia do estresse) ResumoDiversas linhas de evidências sugerem que os efeitos de estressores atuando em populações podem ser calculados acuradamente pela modelagem populacional. Usando dados de monitoramento de populações naturais, modelos populacionais foram aplicados e a possibilidade de estabelecer diagnoses ambientais a partir de conceitos estritamente ecológicos é discutida. Um procedimento é oferecido para a modelagem de dados de populações naturais e o estabelecimento de endpoints populacionais.
