Correction to: Scientific Reports https://doi.org/10.1038/s41598-020-66484-x, published online 11 June 2020
The original version of this Article contained an error in the number of Cetacean Stranding events recorded.
As a result of this, in the Abstract,
“We identified a total of 389 CS events affecting eight cetacean families, 21 genera, and 35 species, which represent more than 85% of the reported species richness for the country.”
now reads:
“We identified a total of 436 CS events affecting eight cetacean families, 21 genera, and 35 species, which represent more than 85% of the reported species richness for the country.”
Additionally, in the Results section under the subheading “Cetacean Stranding Events”,
“Between January 1968 and January 2020, a total of 441 CS events, affecting 1,607 stranded cetaceans, were recorded along the Chilean coast (Fig. 1). Most CS events (94.1%) were single (i.e., ≤ two individuals). There were also 18 mass strandings (three to 24 individuals, 4.1%) and nine unusually large mass stranding event (> 25 individuals, 2%). Cetacean strandings were reported every month; with 20.2% (n = 89) of total events occurring in January, 13.2% (n = 58) in February, and 8.4% (n = 37) in July. (Fig. 2). Spatially, at least one CS event was reported in 15 out of the 16 administrative regions of Chile. When the locations were aggregated by month, it became apparent that most events occurred in the regions of Valparaíso with 17% (n = 75), Magallanes with 14.5% (n = 64), and Coquimbo 11.3% (n = 50). On the opposite end, the region of Araucanía had the least number of reported events with only two strandings (0.5% of all events). The greatest number of CS events was observed in 2019 with 11.3% (n = 50), followed by the year 2018 with 10.7% (n = 47) and 2015 with 9.3% (n = 41). Regarding the numbers of stranded individuals, the greatest numbers of total stranded cetaceans were reported in March with 37.9% (n = 610), followed by July with 16.5% (n = 266) and April with 10.8% (n = 174) (Fig. 2). The Aysén and Magallanes regions accounted for most of the geographical distribution, with a 33.8% (n = 543) and a 31.5% (n = 506) of the total number of stranded individuals, followed by the Coquimbo region with 9.6% (n = 154). The year 2015 also accounted for the highest number of stranding individuals with 25.3% (n = 407) of the total, followed by the years 1989 and 2016 with 11.1% (n = 185) and 9.4% (n = 151) specimens. Overall, the median of stranded cetaceans in an stranding event was 2 with an interquartile range of 3; and the largest number of stranded cetaceans for a given event was 367 Sei whales that were reported at the Golfo de Penas area in the Magallanes region in March 201524.”

“Between January 1968 and January 2020, a total of 436 CS events, affecting 1,596 stranded cetaceans, were recorded along the Chilean coast (Fig. 1). Most CS events (94.1%) were single (i.e., ≤ two individuals). There were also 17 MSE (three to 24 individuals, 3.9%) and nine UME (> 25 individuals, 2.1%). Cetacean strandings were reported every month; with 20.4% (n = 89) of total events occurring in January, 13.3% (n = 58) in February, and 8.5% (n = 37) in July. (Fig. 2).

Also in the Results section, under the subheading “Cetacean species”,
“Cetacean stranding events were reported in eight cetacean families including 21 genera and 35 species. Odontoceti and Mysticeti species accounted for 74.8% (n = 330) and 25.2% (n = 111) of CS events, respectively; while odontocetes accounted for 66.8% (n = 1,073) and mysticetes for 33.2% (n = 534) of stranded cetaceans. Within stranded odontocetes, most events belonged to the Delphinidae 36.3% (n = 160), followed by the Phocoenidae 15.4% (n = 68) and Physiteridae 10.7% (n = 47) families. Delphinidae had the highest number of stranded individuals (n = 865), 80.6% of the Odontoceti order and 53.8% of all cetaceans. In the Mysticeti suborder, individuals of the Balaenopteridae family were the most frequently stranded with 96.3% (n = 514) of cases, followed by members of the Balaenidae family at 3.4% (n = 18). In term of stranding events, 87.4% (n = 97) were composed of Balaenopterids. If all events are considered together, the Delphinidae and Balaenopteridae families account for 58.3% (n = 257) of all stranding events, and for up to 85.8% (n = 1,379) of all cetaceans stranded through the years.”

“Only six odontocetes were classified as undetermined due to their advanced state of decomposition.”

In the first row of Table 1 under the headings “No Individuals” and “No Events”,
“18” and “12”,
now read:
“7” and “7”
and under the heading “Common name”,
“Short-finned Whale” and “Long-finned Whale”
now read:

Figure 1 was incorrect in the original version of the Article (Fig. 1).
Also as a result of the original error, in the Discussion section,
“We also discuss the within-year variation of reporting, the identification of hot spots in different areas of Chile and the species composition of the dataset. In the last year, there have been 61 CS events, 15 of them (24.6%) occurring between December 2019 and January 2020 (last summer season). All these CS events reported a total of 92 stranded individuals that were extensively distributed in the Chilean coast.”

“In fact, from nine existent families, 24 genera and 41 species that have been reported in Chilean waters26, CS events reported here identified 88.9% of cetacean families, 87.5% and 85.4% of genera and species, respectively.”

“This was observable for most species, but it was unusually high for P. spinipinnis, reported in 43 events. Phocoena spinipinnis are a group of porpoises that regularly strand in coastal areas worldwide3. It has been described that the leading causes of death are from bycatch and naval presence28. In our study, the strandings of P. spinipinnis took place for the most part in major ports and fisheries located in central Chile. A different situation occurred with B. borealis (n = 387), with 13 reported CS throughout the study period. However, a single event reported about 95% of total reported stranded individuals.

Additionally, the original Article contained an error in the legend of Figure 3. As a result of this,
“(a) Stranding events (black dots) along Chile since 1968 to 2020. (b) Heatmap that illustrates density of stranding cases along Chile.”

Additionally, the original Article contained an error in the Author Contributions section, where,
“M.A.R. and F.T. led the project, designed the work, collected data and performed the systematic review. M.A.R., F.T., and F.O.M. wrote the paper, and J.E.D., M.S., B.T., C.S.A., J.C., G.C.H., N.Z.V. and A.C.K. helped to improve the manuscript. Time series, spatiotemporal analysis, visualization and plotting results were performed and described by M.A.R., J.E.D. and F.O.M.”
