Cím:Migratory geese allow plants to disperse to cooler latitudes across the ocean / Ádám Lovas-Kiss, Víctor Martín-Vélez, Kane Brides, David M. Wilkinson, Larry R. Griffin, Andy J. Green

Megjegyzések:Aim: How plants can disperse in response to global change is a critical question, yet major knowledge gaps persist about long-distance dispersal (LDD) mechanisms. We studied the potential a migratory waterfowl has for LDD of flowering plants via gut passage of seeds (endozoochory), comparing spring and autumn migration. Location: United Kingdom and Iceland. Taxon: Pink-footed Goose (Anser brachyrhynchus, Baillon) and Angiosperma. Methods: We studied endozoochory by Pink-footed geese migrating within and between the UK and Iceland by faecal sampling and GPS tracking. We collected 614 faecal samples from 14 areas in the UK and one in Iceland. Using GPS tracks to and from these areas, we estimated how far seeds can be dispersed by Pink-footed geese, and where to or from. Results: We recorded 5507 intact seeds of 35 species (27 terrestrial) from 15 plant families, with lower seed abundance per dropping when birds were migrating northwards in the UK during spring than upon their arrival in autumn. Species richness of plant seeds was highest in Iceland and in autumn. Only four plant species dispersed had an "endozoochory syndrome". GPS movements showed that seeds retained in guts for up to 24 h can be readily dispersed in both directions between the UK and Iceland, with maximum distances exceeding 2000 km, as well as between UK localities separated by 100 s of km. Movements northwards of ?400 km were even recorded in autumn. While at stopover sites, daily movements between roost and feeding sites often exceed 20 km. Main Conclusions: Pink-footed geese are LDD vectors for plants previously assumed to lack an LDD mechanism. Spring migration is not the only period when geese move plants to cooler latitudes. The pink-footed goose can allow terrestrial and aquatic plants to cross the ocean and to keep pace with climate change.

Cím:Shorebirds as important vectors for plant dispersal in Europe / Ádám Lovas-Kiss, Marta I. Sánchez, David M. Wilkinson, Neil E. Coughlan, José A. Alves, Andy J. Green
Dátum:2019
ISSN:0906-7590
Megjegyzések:Shorebirds (Charadriiformes) undergo rapid migrations with potential for longdistance dispersal (LDD) of plants. We studied the frequency of endozoochory by shorebirds in different parts of Europe covering a broad latitudinal range and different seasons. We assessed whether plants dispersed conformed to morphological dispersal syndromes. A total of 409 excreta samples (271 faeces and 138 pellets) were collected from redshank Tringa totanus, black-winged stilt Himantopus himantopus, pied avocet Recurvirostra avosetta, northern lapwing Vanellus vanellus, Eurasian curlew Numenius arquata and black-tailed godwit Limosa limosa in south-west Spain, north-west England, southern Ireland and Iceland in 2005 and 2016, and intact seeds were extracted and identified. Godwits were sampled just before or after migratory movements between England and Iceland. The germinability of seeds was tested. Intact diaspores were recovered from all bird species and study areas, and were present in 13% of samples overall. Thirteen plant families were represented, including Charophyceae and 26 angiosperm taxa. Only four species had an ♭endozoochory syndrome'. Four alien species were recorded. Ellenberg values classified three species as aquatic and 20 as terrestrial. Overall, 89% of seeds were from terrestrial plants, and 11% from aquatic plants. Average seed length was higher in redshank pellets than in their faeces. Six species were germinated, none of which had an endozoochory syndrome. Seeds were recorded during spring and autumn migration. Plant species recorded have broad latitudinal ranges consistent with LDD via shorebirds. Crucially, morphological syndromes do not adequately predict LDD potential, and more empirical work is required to identify which plants are dispersed by shorebirds. Incorporating endozoochory by shorebirds and other migratory waterbirds into plant distribution models would allow us to better understand the natural processes that facilitated colonization of oceanic islands, or to improve predictions of how plants will respond to climate change, or how alien species spread.

Cím:Plant traits associated with seed dispersal by ducks and geese in urban and natural habitats / Pál Tóth, Andy J. Green, David M. Wilkinson, Kane Brides, Ádám Lovas-Kiss
Dátum:2023
ISSN:2045-7758
Megjegyzések:Ducks and geese are little studied dispersal vectors for plants lacking a fleshy fruit, and our understanding of the traits associated with these plants is limited. We analyzed 507 faecal samples of mallard (Anas platyrhynchos) and Canada goose (Branta canadensis) from 18 natural and urban wetlands in England, where they are the dominant resident waterfowl. We recovered 930 plant diaspores from 39 taxa representing 18 families, including 28 terrestrial and five aquatic species and four aliens. Mallards had more seeds and seed species per sample than geese, more seeds from barochory and hydrochory syndromes, and seeds that on average were larger and from plants with greater moisture requirements (i.e., more aquatic). Mallards dispersed more plant species than geese in natural habitats. Plant communities and traits dispersed were different between urban (e.g., more achenes) and natural (e.g., more capsules) habitats. Waterfowl can readily spread alien species from urban into natural environments but also allow native terrestrial and aquatic plants to disperse in response to climate heating or other global change. Throughout the temperate regions of the Northern Hemisphere, the mallard is accompanied by a goose (either the Canada goose or the greylag goose) as the most abundant waterfowl in urbanized areas. This combination provides a previously overlooked seed dispersal service for plants with diverse traits.

Cím:Endozoochory of large bryophyte fragments by waterbirds / David M. Wilkinson, Adam Lovas-Kiss, Des A. Callaghan, Andy J. Green
Dátum:2017
ISSN:1290-0796 1776-0992
Megjegyzések:We provide observations confirming that viable fragments of bryophytes are dispersed by migratory birds after surviving transit through the alimentary canal. A specimen of Didymodon insulanus was cultured from a large fragment extracted from faeces of Mallard Anas platyrhynchos at Lake Windermere in Cumbria, England. Similar fragments were recorded elsewhere in England in faeces of Mallard and Lapwing Vanellus vanellus. Endozoochory is likely to be an important dispersal mechanism for bryophyte fragments as well as spores.
