Data for: Geography, taxonomy, extinction risk, and exposure of fully migratory birds to droughts and cyclones
<p class="MsoNormal"><strong>Aim</strong>: Anthropogenic climate change is predicted to drive unprecedented increases in the frequency and intensity of extreme climatic events, such as drought and cyclones. The impacts of these events on fully migratory species could be particularly severe and have cascading effects on the functioning of many ecosystems. We explore the relationships between geography, taxonomy, extinction risk, and the exposure of fully migratory birds to drought and cyclones.</p> <p class="MsoNormal"><strong>Location:</strong> Global.</p> <p class="MsoNormal"><strong>Time period:</strong> 1985-2014.</p> <p class="MsoNormal"><strong>Major taxa studied:</strong> 383 fully migratory bird species.</p> <p class="MsoNormal"><strong>Methods:</strong> We assessed exposure of fully migratory birds to cyclones and droughts, quantifying exposure by calculating the percentage of spatial overlap between a species' range and the extent of an extreme event within a given time series. We compared the level of cumulative exposure sustained by species among different taxonomic groups and within their breeding and wintering ranges; we also assessed whether species currently classed as 'threatened' are more cumulatively exposed than 'non-threatened' species.</p> <p class="MsoNormal"><strong>Results</strong>: We identified fully migratory bird species highly exposed to extreme climatic events and global geographic hotspots of species exposure. 4% of species were found to be highly exposed to cyclones and droughts in both their wintering and breeding ranges. Wintering ranges were, on average, more cumulatively exposed to cyclones than breeding ranges; there was no discernible difference in drought exposure between ranges. Species currently classed as threatened were shown to experience higher exposure to droughts than non-threatened ones in both ranges.</p> <p class="MsoNormal"><strong>Main conclusions:</strong> This exposure analysis provides the first step to a full global assessment of fully migratory bird species' vulnerability to extreme climatic events. Many species are at least as exposed to extreme events within their wintering ranges as in their breeding ranges, supporting calls for 'full cycle' assessment of migratory species' vulnerability to climate change. Our identification of hotspots of exposure may help to guide further monitoring, research, and management.</p>

Three-dimensional renderings from micro-computed tomography data of a developmental series of Numida meleagris: A, TLG NM006; B, TLG NM002; C, TLG NM004; D, TLG NM003; E, TLG NM007 (see Table 1). Skulls are shown in (top) less lateral and (boưom) dorsal views. Casque elements specific to N. meleagris are indicated by coloured cells [dark red (X) = element not participating at specified age; dark green (✓) = element participating at specified age] in the table, and grey cells indicate bones that do not contribute to bones in the species represented in this figure, but do contribute to others in the study. Dashed line divides specimens without (less) and with (right) casques developmentally present.
