Invertebrate propagules may survive internal and external transports by waterbirds, thus facilitating their dispersal between aquatic habitats. However, field data on such transport remain limited, especially for exozoochory. We quantified and compared the rates of internal and external invertebrate transports simultaneously in a wintering population of teal (Anas crecca) in the Camargue (southern France). We inspected lower gut (rectum) contents of birds that had been shot (N = 366) and washed… 
Endozoochory of seeds and invertebrates by migratory waterbirds in Oklahoma, USA
TLDR
A snapshot study investigates the numbers and types of invertebrates and seeds within freshly collected faecal samples of migratory dabbling ducks and shorebirds in November 2008 and underlines the importance of waterbirds as vectors of passive dispersal of many organisms.
Invertebrate dispersal by waterbird species in neotropical wetlands
Abstract Endozoochory by waterbirds is particularly relevant to the dispersal of non-flying aquatic invertebrates. This ecological function exercised by birds has been demonstrated in different
Crayfish invasion facilitates dispersal of plants and invertebrates by gulls
TLDR
Crayfish invasion can lead to novel secondary dispersal pathways for plants and invertebrates through interactions with their predators, promoting the expansion of alien and native species through long-distance dispersal via migratory waterbirds and increasing connectivity of organisms between artificial and natural ecosystems.
Strong potential for endozoochory by waterfowl in a rare, ephemeral wetland plant species, Astragalus contortuplicatus (Fabaceae)
TLDR
The results suggest that avian vectors may be more important for the dispersal of rare higher plants (especially those with a hard seed-coat) than hitherto considered, and suggest that rarity does not necessarily indicate limited dispersal ability, and may instead be explained by specific habitat requirements.
The Role of Waterbirds in the Dispersal of Freshwater Cladocera and Bryozoa in Southern Africa
TLDR
The results indicate that southern African waterbirds do take up the resting eggs of aquatic invertebrates and that these eggs can survive intact through the gut or remain attached to the feathers, and imply that waterbirds may play a vital role in maintaining connectivity between invertebrate populations in isolated wetland patches.
Freshwater ostracods (Crustacea) and environmental variability of polygon ponds in the tundra of the Indigirka Lowland, north-east Siberia
Freshwater ostracods (Crustacea, Ostracoda) are valuable biological indicators. In Arctic environments, their habitat conditions are barely known and the abundance and diversity of ostracods is
Comparing the potential for dispersal via waterbirds of a native and an invasive brine shrimp.
TLDR
Both non-native and native brine shrimps have a similar high capacity for endozoochory via birds, and that the invasiveness of A. franciscana is probably explained by its competitive superiority owing to high fecundity and release from cestode parasitism.
Invertebrate dispersal by aquatic mammals: a case study with nutria Myocastor coypus (Rodentia, Mammalia) in Southern France
TLDR
This study demonstrates the feasibility of ectozoochory in a broad array of freshwater invertebrates by nutria on a local scale and can state that besides modifying aquatic habitats physically by clearing vegetation or digging, nutria may also alter invertebrate communities by introducing new species or genotypes.
Egg morphology may underpin the successful distribution of large branchiopods in temporary waters
Invertebrate species from temporary aquatic ecosystems produce resistant dormant stages (i.e. eggs) that accumulate in long lived mixed egg banks in the sediment. These dormant eggs not only bridge

How frequent is external transport of seeds and invertebrate eggs by waterbirds? A study in Doñana , SW Spain
TLDR
External transport of propagules by waterbirds seems a frequent process at least at a local scale and is likely to facilitate the rapid colonisation of new or temporary wetlands, and maintain gene flow between populations.
Influence of gut morphology on passive transport of freshwater bryozoans by waterfowl in Doñana (southwestern Spain)
TLDR
The results suggest that waterbirds frequently transport bryozoans on a local scale, with lighter gizzards and longer ceca favouring such transport and species and individuals with longer cECA are particularly good candidates for long-distance dispersal of bryzoans, given the longer passage time of propagules that enter the ceca.
The potential role of waterbirds in dispersing invertebrates and plants in arid Australia
TLDR
A role for birds in explaining the distributions of cosmopolitan plant genera such as Lemna, Typha, Myriophyllum and Nitella is supported, as the frequency and duration of flooding of arid-zone wetlands decreases owing to human activities, the importance of waterbirds in facilitating recolonisation of temporary wetlands is likely to increase.
High dispersal capacity of a broad spectrum of aquatic invertebrates via waterbirds
Abstract.Speculation about the role of waterbirds in the dispersal of aquatic invertebrates pre-dates Darwin. However, there is a critical shortage of field studies quantifying such dispersal. We
Transport of brine shrimps via the digestive system of migratory waders: dispersal probabilities depend on diet and season
TLDR
There is potential for long-distance dispersal of brine shrimp Artemia cysts via waders during both northwards (spring) and southwards (autumn) migrations.
The role of migratory ducks in the long‐distance dispersal of native plants and the spread of exotic plants in Europe
TLDR
Migratory ducks are important vectors for both terrestrial and aquatic plant species, even those lacking the fleshy fruits or hooks typically used to identify seeds dispersed by birds, according to a literature review.
Implications of waterbird ecology for the dispersal of aquatic organisms
Dispersal of aquatic organisms by waterbirds: a review of past research and priorities for future studies
TLDR
A literature review indicates that bird-mediated passive transport of propagules of aquatic invertebrates and plants is a frequent process in the field, at least at a local scale, and both endozoochory (internal transport) and ectozooChory (external transport) are important processes.
To sink or float: the fate of dormant offspring is determined by maternal behaviour in Daphnia
TLDR
The moulting behaviour of female Daphnia may determine the fate of their dormant offspring, predetermining whether they remain in the natal environment or disperse, revealing a potential mechanism underlying the high dispersal capacity of freshwater cladocerans inhabiting island-like aquatic habitats.
