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.

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...

Third hospitalized human case of highly pathogenic avian influenza H5N1 in the USA, first case in a resident of Wyoming. The hospitalized woman was likely exposed to the virus by direct contact with an infected poultry flock (but no details on species involved, size of flock or type of system).

Hundreds of ducks found sick or dead of suspected bird flu along Lake Michigan, local conservation group reports CHICAGO — A conservation group in Chicago says hundreds of red-breasted mergansers, a species of diving duck that typically winters in the Great Lakes region, have been found sick or dead of suspec…

About 200 to 300 sick or dead red-breasted mergansers, suspected of highly pathogenic avian influenza H5N1, reported along the shores of Lake MIchigan between this past Friday and Sunday. Birds present with tremors and little ability to move. wgntv.com/news/chicago...

Extinction of experience among ecologists Fieldwork-based research and education in ecology are under multiple threats and are progressively declining. We call for greater attention to this ongoing loss of direct field experience within the ecology community, as it could have widespread consequences for science and education, ultimately hindering efforts to address the ongoing biodiversity crisis.

Where are all the field studies?

This ⬇️ important but rather depressing paper describes how conducting, & crucially initiating, field studies is becoming harder & rarer.

A short 🧵 (and a call for more fieldwork)

Avian influenza rears its head all over Europe - Poultry World For this winter season in many European countries, the first cases of avian influenza in commercial poultry flocks have already been discovered.

Highly pathogenic avian influenza not gone from Europe. Experts have provided clear advice (see for example three-monthly EFSA reports: www.efsa.europa.eu/en/topics/to...), but governments and poultry sector seem slow to follow up. www.poultryworld.net/health-nutri...
