The landscape of fear in cattle farms? How the presence of barn swallow influences the activity of pest flies

Journal of Applied Ecology, Volume 61, Issue 6, Page 1269-1278, June 2024.
Barn swallows are effective biological control agents for lowering pest fly activity in livestock farms. Farmers were actively involved in swallow conservation within their sheds, also with a shared memorandum‐of‐intent. Harnessing the ecosystem services supplied by farmland birds could bring positive outcomes for people and biodiversity.

Impact of dust cooling on direct collapse black hole formation

, 2016
Observations of quasars at $ z > 6$ suggest the presence of black holes with a few times $\rm 10^9 ~M_{\odot}$. Numerous models have been proposed to explain their existence including the direct collapse which provides massive seeds of $\rm 10^5~M_{\odot}
