Abstract

Migratory animals are threatened by human-induced global change. However, little is known about how stopover habitat, essential for refuelling during migration, affects the population dynamics of migratory species. Using 20 years of continent-wide citizen science data, we assess population trends of ten shorebird taxa that refuel on Yellow Sea tidal mudflats, a threatened ecosystem that has shrunk by >65% in recent decades. Seven of the taxa declined at rates of up to 8% per year. Taxa with the greatest reliance on the Yellow Sea as a stopover site showed the greatest declines, whereas those that stop primarily in other regions had slowly declining or stable populations. Decline rate was unaffected by shared evolutionary history among taxa and was not predicted by migration distance, breeding range size, non-breeding location, generation time or body size. These results suggest that changes in stopover habitat can severely limit migratory populations.

28. Continental-scale decreases in shorebird populations in Australia

T., Straw, Phil, Bamford, Mike, Woehler, Eric J., Milton, David A., Weston, Michael A., Venables, Bill, Wellet, Dan, Hassell, Chris, Rutherford, Bill, Onton, Kimberly, Herrod, Ashley, Studds, Colin E., Choi, Chi-Yeung, Dhanjal-Adams, Kiran L., Murray, Nicholas J., Skilleter, Gregory A., and Fuller, Richard A.

Abstract

Decreases in shorebird populations are increasingly evident worldwide, especially in the East Asian—Australasian Flyway (EAAF). To arrest these declines, it is important to understand the scale of both the problem and the solutions. We analysed an expansive Australian citizen-science dataset, spanning the period 1973 to 2014, to explore factors related to differences in trends among shorebird populations in wetlands throughout Australia. Of seven resident Australian shorebird species, the four inland species exhibited continental decreases, whereas the three coastal species did not. Decreases in inland resident shorebirds were related to changes in availability of water at non-tidal wetlands, suggesting that degradation of wetlands in Australia's interior is playing a role in these declines. For migratory shorebirds, the analyses revealed continental decreases in abundance in 12 of 19 species, and decreases in 17 of 19 in the southern half of Australia over the past 15 years. Many trends were strongly associated with continental gradients in latitude or longitude, suggesting some large-scale patterns in the decreases, with steeper declines often evident in southern Australia. After accounting for this effect, local variables did not explain variation in migratory shorebird trends between sites. Our results are consistent with other studies indicating that decreases in migratory shorebird populations in the EAAF are most likely being driven primarily by factors outside Australia. This reinforces the need for urgent overseas conservation actions. However, substantially heterogeneous trends within Australia, combined with declines of inland resident shorebirds indicate effective management of Australian shorebird habitat remains important.

Abstract

Penguins face a wide range of threats. Most observed population changes have been negative and have happened over the last 60 years. Today, populations of 11 of the 18 penguin species are decreasing. Here we present a review that synthesizes details of threats faced by the world’s 18 species of penguins. We discuss alterations to their environment at both breeding sites on land and at sea where they forage. The major drivers of change appear to be climate, and food web alterations by marine fisheries. In addition, we also consider other critical and/or emerging threats, namely human disturbance near nesting sites, pollution due to oil, plastics and chemicals such as mercury and persistent organic compounds. Finally, we assess the importance of emerging pathogens and diseases on the health of penguins. We suggest that in the context of climate change, habitat degradation, introduced exotic species and resource competition with fisheries, successful conservation outcomes will require new and unprecedented levels of science and advocacy. Successful conservation stories of penguin species across their geographical range have occurred where there has been concerted effort across local, national and international boundaries to implement effective conservation planning.

Abstract

The article reports on the challenges facing scientists at research vessels in studying seabird abundance and distribution and the marine ecosystems. Also cited are how ship-based observation programs can complement electronic methods in seabird research, the number of seabird species found in the exclusive economic zone (EEZ) of Australia, as well as some species like red-footed booby, grey-faced petrels, and southern royal albatross.

48. CHANGES IN MIGRATORY SHOREBIRD NUMBERS AND DISTRIBUTIONS IN SOUTH-EAST TASMANIA (1965 - 2014).

Abstract

Migratory shorebirds are primarily found at five locations in south-east Tasmania. Analysis of annual summer and winter shorebird counts indicated that species-specific changes have occurred in the distribution of shorebirds among the five locations. Overall, Holarctic breeding migratory shorebirds have decreased in south-east Tasmania during the last 55 years. Examples include the Curlew Sandpiper Calidris ferruginea and Eastern Curlew Numenius madagascariensis, both listed as Critically Endangered. Curlew Sandpipers, formerly the second most numerous species with numbers exceeding 1000, have become rare visitors to the region. Similarly, the number of Eastern Curlew has decreased by more than 90% compared with around 300 in the 1960s. As their numbers decreased larger species consolidated into a single flock and favoured locations with least disturbed roosts. Smaller species continued to exploit all suitable habitat. At all five locations, there is evidence of deterioration in habitat quality. The decreases in migratory shorebird numbers in south-east Tasmania are consistent with those experienced throughout the East Asian-Australasian Flyway, but exaggerated by its position at southern extremity of the Flyway. While the causes of these decreases at flyway scale may lie primarily outside south-east Tasmania, it is uncertain whether its shorebird habitats remain capable of supporting the peak population levels recorded in the earlier decades of this study. This is of concern if the Flyway's migratory shorebird populations recover and predicted changes in climatic conditions occur shift shorebird distributions towards the southern limits of their range.
