DNA barcode analyses improve accuracy in fungal species distribution models
<p class="western"><span>Species distribution models based on environmental predictors are useful to explain a species geographic range. For many groups of organisms, including fungi, the increase of occurrence data sets has generalized their use. However, fungal species are not always easy to distinguish, and taxonomy of many groups is not completely settled. This study explores the effect of taxonomic uncertainty in databases used for modeling fungal distributions. We analyze distribution models for three morphospecies from the corticioid genus <i>Xylodon</i> (Hymenochaetales, Basidiomycota), comparing models based on species names on vouchers specimens with models derived from species identified by DNA barcode. Differences in the contribution of predictors driving the distribution of each modeled taxon and the extent of their ranges were studied. Records under <i>X</i><i>ylodon</i><i> paradoxus</i>, <i>X</i>.<i> flaviporus</i> and <i>X</i>. <i>raduloides</i> were obtained from fungarium collections and GenBank repository. Two grouping criteria were used: (1) specimens were grouped by their collection or sequence voucher names and (2) specimens were grouped following molecular identification using ITS sequences through barcoding gap species recognition (BGSR). Climatic, geographic and biotic variables were used to predict the potential distribution of each taxon through MaxEnt algorithm. From the three morphospecies selected according to voucher names, up to 19 species candidates were detected using BGSR. Climatic variables were the most important predictors in distribution models made from names on voucher specimens, but their importance decreased when BGSR was applied. In general, the extent of species distributions was more restricted for taxa under BGSR. Our results show that taxonomic uncertainty has a strong effect in <i>Xylodon</i> species distribution models. Misleading results can be obtained when cryptic species or identification errors mask the actual diversity of the presence records. Preserved specimens in natural history collections offer the possibility to assess if the species name on labels matches the current species recognition criteria.</span></p>

Distribution. Currently known from three sets of cranial remains found in New Zealand, Chatham, and Juan Fernandez Is and a single stranding consisting of an adult female and ajuvenile male found in New Zealand. It is not known how these records reflect the actual distribution of this species. in Ziphiidae

Distribution. Most records come from either New Zealand or the Atlantic coast of South America, but also recorded in Tasmania, Western Australia, and South Africa; distribution remains unclear due to the small number of confirmed strandings. There are no records of this species between New Zealand and the Pacific coast of South America, but it is unclear whether this represents a break in distribution or a lack of research activity in this region. Earlier records from the Pacific coast of USA have since been reclassified as Perrin's Beaked Whale (M. perrini). in Ziphiidae

Distribution. Endemic to N Pacific Ocean, the majority ofrecords come from W North America from 32° 42° N to 54° 18' N, also recorded on the Pacific coast ofJapan from 35% to 41° 42° N. This suggests that distribution of this species spans the N Pacific Ocean, but with no records from the C Pacific Ocean, it remains possible that there are separate E and W populations. It has been suggested that distribution of this species is related to the deep current system of the subarctic. in Ziphiidae
