“…Note that R O2 and R CO2 are equivalent to the terms OUR (oxygen uptake rate) and CER (carbon dioxide evolution rate), respectively. Calorespirometry has been used on many different types of biological systems, see for example the following references dealing with mammalian tissue [4], insects [5], plant tissues [6], mammalian cells [4], aquatic microorganisms [7], mold fungi [8], soil [9] and fish [10].…”

“…Understanding the effects of temperature on introduced coccinellids (Acar et al 2001(Acar et al , 2004 and comparisons with native species (Obrycki and Kring 1998) facilitate estimation of interspeciÞc competition. This study compares the respiratory metabolism of adult beetles of two species to determine if physiological differences in temperature responses of metabolism contribute to the displacement of the native species H. convergens by the exotic species, H. axyridis.…”

“…Calorespirometric methodology is much faster and provides much more insight into metabolic responses than direct observation of activity and development times. Direct observation can only show that something happened but does not provide any information on how the observation is related to metabolism (Criddle et al 1997, Hansen et al 1998, Acar et al 2001). …”

Biological invasions are usually examined in the context of their impacts on native species. However, few studies have examined the dynamics between invaders when multiple exotic species successfully coexist in a novel environment. Yet, long‐term coexistence of now established exotic species has been observed in North American lady beetle communities. Exotic lady beetles Harmonia axyridis and Coccinella septempunctata were introduced for biological control in agricultural systems and have since become dominant species within these communities. In this study, we investigated coexistence via spatial and temporal niche partitioning among H. axyridis and C. septempunctata using a 31‐year data set from southwestern Michigan, USA. We found evidence of long‐term coexistence through a combination of small‐scale environmental, habitat, and seasonal mechanisms. Across years, H. axyridis and C. septempunctata experienced patterns of cyclical dominance likely related to yearly variation in temperature and precipitation. Within years, populations of C. septempunctata peaked early in the growing season at 550 degree days, while H. axyridis populations grew in the season until 1250 degree days and continued to have high activity after this point. C. septempunctata was generally most abundant in herbaceous crops, whereas H. axyridis did not display strong habitat preferences. These findings suggest that within this region H. axyridis has broader habitat and abiotic environmental preferences, whereas C. septempunctata thrives under more specific ecological conditions. These ecological differences have contributed to the continued coexistence of these two invaders. Understanding the mechanisms that allow for the coexistence of dominant exotic species contributes to native biodiversity conservation management of invaded ecosystems.
