The effect of climate change on avian offspring production: A global meta-analysis.

Climate change affects timing of reproduction in many bird species, but few studies have investigated its influence on annual reproductive output. Here, we assess changes in the annual production of young by female breeders in 201 populations of 104 bird species (N = 745,962 clutches) covering all continents between 1970 and 2019. Overall, average offspring production has declined in recent decades, but considerable differences were found among species and populations.

[The effect of clofelin on the pain syndrome in mandibular trauma].

Oral clopheline (0.000075) noticeably alleviates the pain syndrome and circulatory hyperdynamic state of patients with mandibular fracture. The agent is superior to the conventional combination of 50% analgin (2 ml) and 1% dimedrolum (1 ml) in its efficiency and duration of action.
