Figure 6 in The trouble with flippers: a report on the prevalence of digital anomalies in Cetacea
Figure 6. Radiograph of the flipper of a rough-toothed dolphin (Steno bredanensis, USNM 504468). Metacarpal I and phalanx 1 are elongated. Phalanges of digits II and III are elongated, and are frequently fused along their anterior aspects (black arrows), and less frequently along their posterior aspects. Scale bar: 1 cm.
Adelie penguin flipper band resightings, 1991 - 2006.
The fundamental long-term objective of the seabird component of the Palmer LTER (PAL) has been to identify and understand the mechanistic processes that regulate the mean fitness (population growth rate) of regional penguin populations. Two hypotheses have guided this research, with one suggesting that population mean fitness is best explained by changes in regional krill biomass, and the other proposing that long-term changes in sea ice affects mean fitness by tipping the balance in favor of one species over another in accordance with species-specific evolved life history affinities to sea ice. Although these hypotheses are not mutually exclusive, current evidence in the PAL region tends to favor the latter over the former. Since the inception of PAL, Adélie penguin populations have effectively collapsed, while those of gentoo and chinstrap penguins have increased dramatically, trends that are spatially and temporally coherent with decreasing regional sea ice duration. Adélie penguins are an ice-obligate polar species whose life history is intimately linked to the presence of sea ice, while chinstrap and gentoo penguins are ice-intolerant species whose life histories evolved in the sub-Antarctic, where sea ice is a less permanent feature of the marine ecosystem. In contrast, although krill constitute the most important component of the summer diets by mass of these three penguin species, changes in PAL krill abundances have exhibited no long-term trends, and thus fail to explain the divergent patterns in penguin populations evident in our time series. Annually between 1991 and 1998, a subsample of 1000 Adélie penguin crèche-age chicks were flipper-banded on Humble Island as part of demographic studies to determine long-term survival and recruitment. This was achieved through resighting efforts in the years that followed the banding work through 2006 when the last banded bird was observed. The decision to end the banding studies is in concordance with other national
