Temporal Dynamics of a Neotropical Plant‐Hummingbird Interaction Network

Austral Ecology, Volume 50, Issue 7, July 2025.
Using an unprecedented sampling effort we evaluated network structure and dynamics of plant‐hummingbird interactions over 1 year in the Brazilian hyperdiverse Campos Rupestres. Network structure presented remarkable temporal change, showing that tropical communities can also be strongly influenced by climate.

In the nectar, there are answers: exploring the intersection of colored nectars and reactive oxygen species in manipulating pollinator behavior

New Phytologist, Volume 246, Issue 3, Page 901-910, May 2025.
Summary Nectar, a vital mediator of plant–pollinator interactions, exhibits remarkable chemical diversity beyond sugars, including reactive oxygen species and specialized metabolites such as pigments. Colored nectars, present in over 70 species, function as visual signals, inhibitors of microbial growth, or nutritional rewards, underscoring their ...

Multiomics analysis revealed that the metabolite profile of raw milk is associated with the lactation stage of dairy cows and could be affected by variations in the ruminal microbiota

Journal of Dairy Science
: The nutritional components and quality of milk are influenced by the rumen microbiota and its metabolites at different lactation stages. Hence, rumen fluid and milk samples from 6 dairy cows fed the same diet were collected during peak lactation, early
