Achievements, challenges, and recommendations for waterbird conservation in China's coastal wetlands

Avian Research, Год журнала: 2023, Номер 14, С. 100123 - 100123

China's coastal wetlands provide breeding, migration stopover, and wintering habitats for about 230 waterbird species, which is more than a quarter of all waterbirds in the world. Large-scale high intensity human activities have resulted serious loss degradation over past half century, causing population declines many waterbirds. Through literature review expert surveys, this article reviews conservation measures taken recent decades to conserve provides recommendations future action from three aspects: policy administration, habitat management, multiparty participation. Over decades, legislation, regulations plans at national level site-specific interventions been implemented, with notable improvement effectiveness making multi-stakeholder Accordingly, some threats mitigated key sites designated as strictly protected nature reserves. However, critical issues still remain, mostly related such wetland restoration, control invasive Spartina alterniflora, environmental pollution, artificial quality. We highlight that protecting natural tidal improving quality are waterbirds, especially those highly dependent on intertidal wetlands. China has demonstrated strong commitment ecological restoration future, terms both funding policies biodiversity ecosystems. It important supported continuously by science- evidence-based decisions actions.

Shorebirds-driven trophic cascade helps restore coastal wetland multifunctionality

Nature Communications, Год журнала: 2023, Номер 14(1)

Опубликована: Дек. 6, 2023

Abstract Ecosystem restoration has traditionally focused on re-establishing vegetation and other foundation species at basal trophic levels, with mixed outcomes. Here, we show that threatened shorebirds could be important to restoring coastal wetland multifunctionality. We carried out surveys manipulative field experiments in a region along the Yellow Sea affected by invasive cordgrass Spartina alterniflora . found planting native plants alone failed restore multifunctionality experiment. Shorebird exclusion weakened multifunctionality, whereas mimicking higher predation before shorebird population declines excluding their key prey – crab grazers enhanced The mechanism underlying these effects is simple cascade, whereby control otherwise suppress recovery destabilize sediments (via bioturbation). Our findings suggest harnessing top-down of through habitat conservation, rewilding, or temporary simulation consumptive non-consumptive should explored as nature-based solution degraded wetlands.

The causes and implications of sex role diversity in shorebird breeding systems

Ibis, Год журнала: 2023, Номер 166(2), С. 357 - 385

Опубликована: Окт. 11, 2023

Males and females often exhibit different behaviours during mate acquisition, pair‐bonding parenting, a convenient label to characterize these is sex role. The diverse roles that male female shorebirds (plovers, sandpipers allies) in mating parenting have played key role advancing mainstream theories avian ecology behavioural biology including sexual selection, conflict parental cooperation. Recent advances shorebird research also highlighted the significance of social environment driving by linking adult ratio with breeding behaviour population demography. Here we review using as an ecological model system. We identify knowledge gaps argue untapped potential accelerate fields evolutionary genomics, movement ecology, networks environmental changes. Future studies will benefit from individual‐based monitoring advanced tracking technologies, multi‐team collaborations are facilitated standardized data collection methodologies across species field. These not only contribute our understanding reproductive strategies, but they knock‐on effects on predicting resilience changes prioritizing for conservation.

Study on the impact of reclamation and development of Yancheng coastal wetlands on the spatio-temporal evolution of wintering Anatidae habitat

Ecological Indicators, Год журнала: 2024, Номер 160, С. 111892 - 111892

As a World Natural Heritage Site primarily focused on protecting migratory bird habitats, the Yancheng coastal wetland is also an important land resource reserve area in China. With long history of reclamation, impact reclamation waterbird habitats has attracted widespread attention. Therefore, this study was based distribution data wintering Anatidae from 1987 to 2020 and data. The landscape development intensity (LDI) index MaxEnt model were used reveal spatiotemporal changes identify evolution characteristics habitats. A geographical weight regression (GWR) analyze local differences for results showed that types with higher increased rapidly 2020, overall pattern low northeast high southwest. high-intensity range 5.01 ∼ 6.00, western Dafeng Tiaozini generally greater than 8.01 2020.

Deteriorating habitat suitability and connectivity of waterbirds in the Bohai Sea Rim: Consequences of land use transformation

Wetlands in the Bohai Sea Rim play an indispensable role maintaining stability of waterbird populations on East Asian-Australian flyway. However, motivated by economic development and urban expansion, coastal wetlands this region have been extensively reclaimed, leading to a decline area degradation natural over past two decades. We analyzed temporal spatial changes suitable habitats different groups waterbirds quantified habitat connectivity importance patches using Probability Connectivity. The results show that all decreased sharply from 2000 2020. In addition, utilization ratio artificial increased. Land use is primary environmental variable determining distribution habitats. Meanwhile, has also declining. Tianjin Hebei Bay still high for waterbirds, particularly shorebirds. Expanding existing protection areas cover above-mentioned recommended. advocate stricter measures necessary ecological restoration activities both wetlands.

Importance of habitat heterogeneity in tidal flats to the conservation of migratory shorebirds

Conservation Biology, Год журнала: 2023, Номер 38(1)

Опубликована: Авг. 8, 2023

Abstract Understanding species distribution patterns and what determines them is critical for effective conservation planning management. In the case of shorebirds migrating along East Asian‐Australasian Flyway (EAAF), loss stopover habitat in Yellow Sea region thought to be primary reason precipitous population declines. However, rates decline vary considerably among species, it remains unclear how such differences could arise within a group closely related using apparently similar habitats at same locales. We mapped spatial distributions foraging shorebirds, as well biotic (benthic invertebrates consumed by shorebirds) abiotic (sediment characteristics) environmental factors, key site eastern China. Five six sediment characteristics showed significant variation with respect distance shoreline or from seawall tidal flat. The biomasses four most abundant benthic were concentrated upper middle zones all three focal shorebird on flat best explained jointly this heterogeneity invertebrate prey. These results suggest that flats Sea, which typically zones, may not only reduce overall amount staging habitat, but also disproportionately affect resource‐rich portions birds. Effective areas EAAF likely elsewhere must consider subtle characterizes these flats, prioritizing protection those richest food resources, frequently used bird vulnerable anthropogenic threats.
