Non-passerine birds from Laguna Melincué Ramsar Site, Santa Fe province, Argentina [PDF]

, 2015
We present a waterbird inventory of the Laguna Melincué Ramsar Site in southern Santa Fe province, Argentina. We record 109 species from 28 families of non-passerine birds, including the 14 Nearctic species, four southern austral migrant species, three ...

Drone‐based radiotelemetry and imagery systems provide an advantage over traditional techniques for estimating survival of dependent juveniles

Wildlife Society Bulletin, EarlyView.
We used drone‐based radiotelemetry and multispectral imagery to estimate detection and survival probabilities of blue‐winged teal broods in Saskatchewan, Canada. Weekly brood survival probabilities, estimated via Cormack‐Jolly‐Seber models, increased with age and were comparable between drone methods.

Carnivorous Waterbirds Community Composition and Diversity in Freshwater Tributaries of Zambezi River, Namibia

, 2023
Carnivorous waterbirds have been reported to enhance wetlands diversities, control pests, bio-indicators of ecological conditions, and act as indicators of potential disease outbreaks. They also provide important ecosystem services to indigenous communities residing along wetlands.

Regional conservation planning tool: A spreadsheet model to support spatial prioritization and resource allocation decisions

Wildlife Society Bulletin, EarlyView.
Abstract Prioritization is a central component of natural resource management because conservation needs routinely exceed available resources. Waterfowl and wetland conservation programs in North America are at the forefront of landscape‐scale prioritization and transboundary management decisions due to the migratory nature of ducks, geese, and swans ...

Diet, phenology and body size shape nutrient release by songbirds

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Animals can dramatically alter ecosystem structure and function through the cycling and transport of nutrients in their waste. While birds are particularly capable of influencing nutrient cycles due to their high mobility, abundance, metabolism and functional diversity,

Functional diversity dynamics of waterbird communities driven by water levels at Shengjin Lake, a small river‐connected shallow lake in the middle and lower Yangtze River floodplain

Ecology and Evolution
Gate‐controlled activities in lakes can directly or indirectly influence the assembly of waterbird communities. Shengjin Lake, a Ramsar site, is a typical river‐connected and gate‐controlled shallow lake in the lower and middle Yangtze River floodplain ...

Patterns and drivers of waterbird alpha and beta diversity are different between arid and humid regions of China

Avian Research
Waterbirds are vital for wetland ecosystems, but climate change and human activities are harming these habitats globally, reducing biodiversity and threatening waterbird survival. In China, wetlands in humid and arid regions face quite different threats,

Diversity of waterbird species in the Sicanang Belawan mangrove ecotourism area

IOP Conference Series: Earth and Environmental Science
Abstract Waterbirds are a group of birds highly dependent on wetlands, aquaculture ponds, mudflats, mangroves, and coastal areas. The Sicanang Mangrove Ecotourism Area serves as one of the habitats for these waterbirds. However, currently the condition of the mangroves in the Sicanang Mangrove Ecotourism Area has declined, affecting the ...

Mobile consumers influence the shoreward edge of intertidal seagrass ecosystems

Journal of Animal Ecology, EarlyView.
Ecological paradigms suggest that the environmentally stressful edge of a habitat is determined by physical factors. The work finds that, counter to these paradigms, an environmentally stressful edge can also be impacted by biotic interactions and are more complex than suggested.
