“…Morphological comparison has a long history of use in the field of taxonomy. It is only relatively recently, with the advent of powerful computing and user-friendly technology, that environmental niche modeling (ENM) has become an additional tool for taxonomists and biogeographers of Hymenoptera (Gonzalez et al, 2010;Bassin et al, 2011;Wilson et al, 2012;Lozier et al, 2013). As the ENM approach has been successful at predicting evolutionary relationships across Hymenoptera, we predict comparable success when testing our A. curta/A.…”

“…MaxEnt v3.3.3 (Phillips et al, 2006) was employed to construct the ENMs as this algorithm has proven the most useful in estimating habitat suitability of various taxa, including bees (Hinojosa-Díaz et al, 2009;Gonzalez et al, 2010;Lozier et al, 2013). The MaxEnt algorithm, which uses the principle of maximum entropy, is discussed in great detail in both computational and ecological contexts in Phillips et al (2006) and Elith et al (2010), respectively.…”

Taxonomy has far-reaching effects throughout biology, and incorrect taxonomy can be detrimental in many ways. Polymorphic species complexes, many of which exist in the bee genus Anthophora Latreille, lend themselves to such difficulties. This study employs environmental niche mapping (ENM) and traditional morphological analyses to investigate the validity of the subjective synonymy of Anthophora (Heliophila) curta Provancher with the senior synonym A. squammulosa Dours. Eleven of fifty morphological characters consistently differentiate the two putative species, with an additional five characters sometimes separating them. Additionally, based on over 1000 georeferenced museum specimens, the geographic ranges of the two taxa do not overlap. The two entities also react differently to the bioclimatic variables based on correlation analysis. We further tested the two-species hypothesis by constructing ENMs with informative bioclimatic variables associated with locality records. Their modelled distributions overlapped less than 1%, suggesting discrete environmental boundaries. The variables which contributed most to each species' model also differed. These differences are explored in relation to their habitats. The combined morphological and biogeographic analysis indicates that A. curta and A. squammulosa are distinct species. Based on the accumulated evidence the synonymy is formally rejected and A. curta is recognized as a valid species. Five additional taxa (A. bispinosa Cockerell, A. franciscana Cockerell, A. usticauda Cockerell, A. u. cinerior Cockerell, A. zamoranella Cockerell) are newly synonymized with A. squammulosa and Anthophora curta var. melanops Cockerell is newly synonymized with A. curta. Implications outside of taxonomy are discussed.

“…Species distribution modeling (SDM) based on observed occurrences are good tools for predicting the potential distribution of exotic species including bees (e.g., Hinojosa-Díaz et al 2005, 2009, Gonzalez et al 2010, Silva et al 2014. Incorporating biotic interactions in these models, such as plant-bee relationships, is expected to have a major influence on the modeled distribution.…”

“…These biologically meaningful variables have proven useful in predicting the distribution of many different organisms, including bees (e.g., Gonzalez et al 2010).

Global invasion by Anthidium manicatum (Linnaeus) (Hymenoptera: Megachilidae): assessing potential distribution in North America and beyond

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.
