A national assessment of waterbird hunting in coastal wetlands of Suriname, South America

open access: yesConservation Science and Practice
The central northern coast of South America has extensive wetlands critical for waterbird conservation. While waterbird harvest occurs in the region, the impact on species population dynamics remains unclear.

Reproductive Characteristics of the Captive Milky Stork (Mycteria cinerea) in Zlin Zoo, Czech Republic

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2022
The limited range of Milky Stork in its natural habitat, as well as in under captivity, makes it difficult to learn more about it. This paper aimed to examine the breeding biology of Milky Stork raised in captivity in the Zlín-Lešná Zoo in the Czech ...

Human activities accelerated the degradation of saline seepweed red beaches by amplifying top‐down and bottom‐up forces [PDF]

open access: yes, 2018
Salt marshes dominated by saline seepweed (Suaeda heteroptera) provide important ecosystem services such as sequestering carbon (blue carbon), maintaining healthy fisheries, and protecting shorelines. These salt marshes also constitute stunning red beach

Evaluation of fall‐seeded cover crops for grassland nesting waterfowl in eastern South Dakota

open access: yesWildlife Society Bulletin, EarlyView., 2023
Cover crops are experiencing a revival among Midwestern farmers, and we assessed their attractiveness and safety for nesting ducks in South Dakota. Nest success was markedly lower in cover crops than in perennial cover during both years of our study, including 2019 which was a best‐case scenario for cover crops, with extremely wet conditions delaying ...

Cliff top habitats provide important alternative feeding resources for wading birds of conservation importance wintering on non-estuarine coasts [PDF]

open access: yes, 2014
Rocky shores and beaches are important over-wintering areas for non-estuarine waders but have rarely been studied. We examined cliff top habitat use by 6 species of wader over 75 km of coast to assess their potential value as alternative feeding sites to

Gravel pits support waterbird diversity in an urban landscape [PDF]

open access: yes, 2009
We assessed the benefit of 11 gravel pits for the settlement of waterbird communities in an urbanized area lacking natural wetlands. Gravel pits captured 57% of the regional species pool of aquatic birds.

Comparative Analysis of Gut Microbiota Among Captive Waterbird Species: Effects of Diet and Environmental Factors. [PDF]

open access: yesVet Med Sci
This study reveals that diet drives gut microbiota differences in captive waterbirds (bar‐headed goose, ruddy shelduck, black‐necked crane), with protein‐rich diets shaping distinct microbial communities. Artificial lakes enhance microbial diversity compared to enclosures, offering insights for improving captive waterbird health.

Can aggregate quarry silt lagoons provide resources for wading birds? [PDF]

open access: yes, 2017
Wading birds have declined across Europe as the intensification of lowland agriculture has resulted in the loss and degradation of wetland areas. Lowland aggregate extraction sites that incorporate areas of fine, waste sediments deposited in silt lagoons

Regional Genetic Structure in the Aquatic Macrophyte Ruppia cirrhosa Suggests Dispersal by Waterbirds [PDF]

open access: yes, 2017
The evolutionary history of the genus Ruppia has been shaped by hybridization, polyploidisation and vicariance that have resulted in a problematic taxonomy. Recent studies provided insight into species circumscription, organelle takeover by hybridization,

Mechanisms promoting higher growth rate in arctic than in temperate shorebirds [PDF]

open access: yes, 2002
We compared prefledging growth, energy expenditure, and time budgets in the arctic-breeding red knot (Calidris canutus) to those in temperate shorebirds, to investigate how arctic chicks achieve a high growth rate despite energetic difficulties ...
