“…4b), further suggesting that the model is not effective at predicting invasive distribution. Unlike similar studies of invasiveness (e.g., Broennimann and Guisan 2008;Steiner et al 2008), pooling native and invasive A. manicatum locality data did not improve model predictions. Thus, our analysis represents a narrow geographic approach in modeling the invasive potential of A. manicatum.…”

The wool carder bee, Anthidium manicatum, is the most widely distributed unmanaged bee in the world. It was unintentionally introduced to North America in the late 1960s from Europe, and subsequently, into South America, New Zealand and the Canary Islands. We provide information on the local distribution, seasonal abundance and sex ratio of A.manicatum from samples collected in an intensive two-year survey across Utah, USA. Anthidium manicatum was detected in 10 of the 29 Utah counties, largely in urban and suburban settings. Combining presence-only and MaxEnt background data from literature, museum databases and new records from Utah, we constructed three species distribution models to examine the potential distribution of A. manicatum in its native Eurasian range as well as invaded ranges of North and South America. The A. manicatum model based on locality and background data from the species' native range predicted 50% of the invasive records associated with high habitat suitability (HS C 0.90). The invasive North American model predicted a much broader distribution of A. manicatum (214% increase); whereas, the South American model predicted a narrower distribution (88% decrease). The poor predictive power of the latter model in estimating suitable habitats in the invasive South American range of A. manicatum suggests that the bee may still be limited by the bioclimatic constraints associated with a novel environment. Estimates of niche similarity (D) between the native and invasive models find that the North America bioclimatic niche is more similar to the bioclimatic niche of the native model (D = 0.78), whereas the bioclimatic niche of the South America invasion is relatively dissimilar (D = 0.69). We discuss the naturalization of A. manicatum in North America, possibly through punctuated dispersal, the probability of suitable habitats across the globe and the synanthropy exhibited by this invasive species.

“…Ecological niche models assume equilibrium of species' distribution with current climate (i.e., the range is determined by the current niche and not strongly affected by stochastic processes, especially dispersal and other historical processes-see Araújo and Pearson 2005) and, under these circumstances, they allow accurate predictions of future distributions following introduction to a new area or in response to altered environmental conditions under niche conservatism (Guisan and Zimmermann 2000). Thus, the degree of correspondence between the geographical distributions of invasive species, in their native and introduced ranges, can help in the investigation of the niche conservative hypothesis (Broennimann et al 2007;Fitzpatrick et al 2007;Steiner et al 2008). However, it is important to consider that the variables used in modeling processes usually reflect only particular components of a species' niche (Soberon 2007) and that methodological issues and idiosyncratic characteristics of niche models must also be ruled out (Araujo and Guisan 2006;Peterson 2007;Peterson and Nakazawa 2008).…”

Invasive and flexible: niche shift in the drosophilid Zaprionus indianus (Insecta, Diptera)

et al. 2009

Although predictions of potential distributions of invasive species often assume niche conservatism, recent analyses suggest that niche shifts can also occur. Thus, further studies are necessary to provide a better understanding of niche dynamics and to predict geographic distribution in invaded areas. The present study investigated the niche shift hypothesis at a broad biogeographical scale, using the comprehensive distribution of the invasive species Zaprionus indianus in its native (Africa) and invaded (America and India) ranges. Z. indianus is a very successful invasive species that presents high adaptive flexibility and extreme physiological tolerance. To investigate whether Z. indianus changed its climatic niche from Africa to America and India, multivariate analyses, as well as ecological niche modeling procedures (GARP, MAXENT and Mahalanobis distances), were used. Multivariate analyses showed that the niche spaces of Z. indianus in Africa, India and the Americas were significantly different (Wilks' k from a Multivariate Analysis of Variance, MANO-VA = 0.115; P \ 0.0001). Out of 108 occurrences in America, only 11 (ca 10%) were classified, by Canonical Variate Analysis scores, as belonging to its original range in Africa, whereas only 5% of the 39 occurrences in India were classified as belonging to Z. indianus' original range. Consensus results from MAXENT, GARP and Mahalanobis distances correctly predicted only 27% of the occurrences in India and 85% of occurrences in America. Thus, all analyses showed that Zaprionus indianus quickly expanded ranges into different environments in the invaded areas, suggesting climatic niche shifts, primarily in India.

“…In this study, we used data only from the invaded range, because zooplankton, temperature, salinity, and water column stratification data are not available from published literature about the native habitats of Pseudodiaptomus inopinus: we conducted a thorough literature search and found only a few publications that generally related P. inopinus abundances to brackish waters (Suh et al 1991;Ueda et al 2004;Islam et al 2006). However, a case can also be made for using data from the invaded range, because the factors that limit the growth and spread of species in the native region may differ from those in the invaded region, i.e., it occupies different realized niches within its fundamental niche in each region (Drake and Bossenbroek 2004;Loo et al 2007;Steiner et al 2008). In the case of P. inopinus, it appears for the time being to have reached the limits of its physico-chemical tolerances along the west coast of North America, because its distribution has remained static since 1992, and thus this case may represent a good scenario for predictive modelling using invaded range data.…”

Modelling physico-chemical factors affecting occurrences of a non-indigenous planktonic copepod in northeast Pacific estuaries

Estuarine ecosystems along the Pacific coast of North America are vulnerable to invasions by non-indigenous planktonic copepods, with documented invasions by at least nine species introduced via ship's ballast. One of these, the calanoid copepod Pseudodiaptomus inopinus, now occurs in a relatively wide geographical area in coastal estuaries of Washington and Oregon States. Although it appears to be well established in the region, plankton surveys conducted in 1992, 1996, 2000, and 2004 in estuaries from southern Vancouver Island in British Columbia, Canada, to northern California, United States indicate that it has not expanded its range. This static distribution suggests that P. inopinus has reached a distributional limit, and it may thus be a good organism for applying models for predicting planktonic invasions, by characterizing estuaries with and without populations of the copepod. In this study, we applied both parametric, linear (discriminant function analysis, logistic regression) and nonparametric, nonlinear (classification trees) techniques to develop models for occurrence of P. inopinus, to identify parameters that may lead to successful invasions and to identify specific estuaries or regions that might be at risk of invasion by this species. Both model types had similar results, identifying relatively simple salinity-and stratification-based models as good predictors of P. inopinus. While different models selected slightly different sets of variables and thresholds, all models identified relatively low salinity and stratification of water column temperature and salinity as important predictors of P. inopinus presence. The models also identified several ''false positives'' that mainly occurred in more inland waters of Puget Sound-estuaries that did not have P. inopinus, but had the conditions that support it, and which may be at risk for future invasions by this species.
