Large parameter uncertainty persists in soil food web models integrating stoichiometry, respiration and assimilation

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Soil food web models are essential for linking animal diversity to carbon and nutrient cycling. However, it is unclear how soil animals regulate excess carbon when nutrient availability limits their growth and how to best represent animal respiration in these models. To

Taxonomic and functional diversity of urban bees of the world

open access: yesConservation Biology, EarlyView.
Abstract Bees play a pivotal role in terrestrial environments. Urbanization can affect these organisms and the ecosystem services they provide. However, knowledge of the global diversity of urban bees is limited. Thus, we summarized data on urban bee species identities and occurrences; compared distributions of all bees with those found in urban ...

Experimental Assessment of Epipelon Responses to Phosphorus Limitation in a Eutrophic Lake

open access: yesEcological Research, Volume 41, Issue 6, November 2026.
We evaluated the responses of epipelic algal and cyanobacterial communities to increasing phosphorus limitation in the water column under eutrophic conditions. Nitrogen enrichment increased the N:P ratio and intensified phosphorus limitation in the water column, promoting changes in community composition. The greater contribution of cyanobacteria (e.g.,

Lack of Compliance in Gillnet Fisheries Regulations Increases Risk to a Vulnerable Species

open access: yesFisheries Management and Ecology, Volume 33, Issue 5, Page 933-948, October 2026.
ABSTRACT This article presents an analysis of regulatory compliance in a Brazilian gillnet fishery, based on Vessel Monitoring System (VMS) tracking data. Satellite transmissions records, interpreted as proxies for gillnet haulings events, were analyzed and classified using a neural network to assess the level of compliance of the gillnet fleet.
