Our new paper shows good establishment of wetland plants after seed dispersal inside waterfowl, but plants grow better when seeds are first removed from the faeces (e.g. when poo falls into water) #endozoochory @ebdonana.bsky.social @freshwaterscience.bsky.social academic.oup.com/aob/advance-...
Plant height measured at 7, 15, 30 and 45 days after germination for (a) J. bufonius and (b) E. palustris. Curves were obtained from the fitted logistic base functions (Table 1), and points represent measured height for individual plants. Treatments including faeces addition (CF, IF) are represented in pink and treatments including gut passage (IF, INF) with dashed lines. Asterisks represent mean xmid parameters for treatments grouped with faeces (pink) and without faeces (green). CF = control, faeces; CNF = control, no faeces; IF = ingested, faeces; INF = ingested, no faeces.

Our publication "Dispersal of aquatic and terrestrial organisms by waterbirds: A review of current knowledge and future priorities" is a "Highly cited paper" according to ISI Essential Science Indicators Database 2024 😀 @ebdonana.bsky.social onlinelibrary.wiley.com/doi/full/10....
Land–water transition zone from terrestrial to littoral to pelagic habitat, illustrating organisms shown to be capable of endo- or ectozoochorous dispersal by waterbirds of the Anatidae and/or Rallidae families. Major taxonomic groups are indicated by the larger font, and key families known to be dispersed in the smaller font. Words in brackets indicate the resting stages dispersed. For each group, representative organisms are drawn in their typical habitat. Blue represents aquatic habitats, brown represents terrestrial habitat and lake sediments. See the paper for more details of these dispersal interactions

Today I learned from this "ONE" profile that I seem to be an expert in "marbled meat" and "White (mutation)". I guess the former comes from "marbled teal", the latter I just don't know.... Some other things there make more sense...

Branchinecta and Artemia franciscana from the Saskatchewan region genetic distances, measured as Kimura 2-parameter (K2P) distances in relation to spatial distance, based on the mitochondrial CO1 gene fragment. There was a significant distance decay in the assembled dataset (Mantel test; nperm = 999; Branchinecta: r = 0.485, P < 0.001; A. franciscana: r = 0.149, P < 0.001); (b) Mantel correlogram for genetic distance (Hellinger-transformed) and geographic distance + 0.1 (log-transformed) in Branchinecta and A. franciscana from the study lakes in Saskatchewan, Canada.

But different species within a guild show interesting differences in their "dispersal niche", as exemplified when looking at the "dispersal syndromes" of the different plants they disperse. Species from different guilds can share a similar niche represented by network modules @ebdonana.bsky.social
Bipartite network plot representing the proportion of interactions of each waterfowl species with plant species assigned different morphological dispersal syndromes, indicated on the left-hand side. Waterfowl species are organised into four modules (clusters of bird species dispersing similar plants), represented by alternating shades of grey. The classification of species into foraging groups is shown in the coloured vertical column to the right of bird species names. Further to the right, horizontal bars show the number of plant species of each dispersal syndrome whose seeds were recorded in each waterfowl species.

New paper explores traits of >500 plants whose seeds are eaten, and dispersed, by 38 waterfowl species in North America. A great variety of plants are included, but with strong differences between difficult "guilds" such as dabbling and diving ducks, or geese doi.org/10.1111/fwb....
Distributions of plant height and seed mass community weighted means (CWM), proportions of sublittoral and terrestrial plant species, and proportions of plant species with hydrochory and unspecialized syndromes in the seeds recorded in each waterfowl foraging group. Both CWMs and proportions were calculated weighting each plant species by the number of studies in which it was recorded. Box and whiskers represent medians and quartiles for observed values, large black dots represent fitted values according to the best models, and small coloured dots represent outliers. Letters above boxplots represent significant differences between groups according to pairwise tests. For diaspore mass and plant height, both observed and fitted values are log10 transformed to ease visualisation. Swans were excluded due to lack of data.

Waterbirds have fascinating ecological interactions with brine shrimps, fairy shrimps and other large branchiopods, nicely documented in this new review @zsofiahorvath.bsky.social @aillimnologia.bsky.social @sil-limnology.bsky.social @freshwaterscience.bsky.social link.springer.com/article/10.1...
Support for trophic links between different families of waterbirds and four groups of large branchiopods. a Trophic relationships between waterbird families and large branchiopod groups in literature. The thickness of the connecting line is proportional to the number of studies supporting evidence for a trophic link. Both large branchiopod and waterbird diversity (n = number of species) are denoted below their corresponding group icon. For all families depicted, direct evidence of branchiopod consumption was found with the exception of spoonbills (Threskiornithidae), for which only indirect (prey availability) evidence was found (transparent). b Quantitative measures of large branchiopod consumption by waterbirds from gastrointestinal studies. Percentages of bird samples containing the large branchiopod group (occurrence) and percentages of volume of gastrointestinal bird samples aggregate that consist of large branchiopods (volume) are depicted where available (tr < 1%, traces). Percentages were weighted according to the number of samples (n) across the number of studies (N) and weighted standard errors are depicted as error bars where applicable.

a) Geographic distribution of examined lakes in Saskatchewan and anostracan taxa found in them; b) Bliss lake, one of the sites with Branchinecta; c) one small edge of Bliss lake with numerous Branchinecta swimming in the water (tiny white stripes). a) Branchinecta (blue) and Artemia franciscana (yellow) from the Saskatchewan region genetic distances measured as Kimura 2-parameter (K2P) distances in relation to spatial distance, based on the mitochondrial CO1 gene fragment. There was a significant distance decay in the assembled dataset (Mantel test; nperm=999; Branchinecta: r = 0.485, P < 0.001; A. franciscana: r = 0.149, P < 0.001). b) Mantel correlogram for genetic distance (Hellinger-transformed) and geographic distance (log-transformed) in Branchinecta and A. franciscana from the lakes we studied in Saskatchewan, Canada. The filled circles indicate significant correlation within each distance class.

In the 60 year history of @ebdonana.bsky.social there have only been 3 chinese PhD students. I am supervising 2 of them: Yang studies dispersal of bryozoans and other invertebrates by waterbirds, Yingjun studies movement ecology of black-headed gulls and bald ibis. Both have CSC scholarships

Our paper in the new issue of Freshwater Biology shows greylag geese are great seed dispersal vectors for 24 plant species in #Doñana, and the decline in their population and duration of winter visits is impacting connectivity between plant populations onlinelibrary.wiley.com/doi/10.1111/...
GPS data for three tagged greylag geese within the study area between 6 November 2021 and 8 February 2022. The geese arrived on 6 (17,599) or 23 November (17,592, 17,594, two parallel lines indicate how they arrived in the same flock from the north-east) and departed on 2 (17,592), 7 (17,594) or 8 (17,599) February. Non-metric multidimensional scaling (NMDS) showing the dissimilarities in plant taxa composition among the greylag geese faeces collected in five different sampling events (stress value 0.06). The names of taxa shared between two or more sampling events are indicated in black, whereas names of taxa present in only one sampling event have the colours indicated in the legend. There is no polygon for the event ERF, as this would simply be a line joining Juncus bufonius with Helitropium supinum. Simulated seed deposition locations for endozoochory events starting at the four faecal sampling sites. Nineteen per cent of the locations are situated outside the polygon of origin. Note how seeds can be dispersed from El Rocío to Hato Blanco, but not the other way around.
