Environmental and local habitat variables as predictors of trophic interactions in subtidal rocky reefs along the SE Pacific coast

open access: yesEcography, EarlyView.
Temperature generally drives latitudinal patterns in the strength of trophic interactions, including consumption rates. However, local community and other environmental conditions might also affect consumption, disrupting latitudinal gradients, which results in complex large‐scale patterns.

Harnessing the power of machine and deep learning for transferring joint species distribution models considering the structure of biotic interactions

open access: yesEcography, EarlyView.
The transferability of single or joint species distribution models ((j)SDMs) depends on their ability to predict beyond the observed environmental range and to remain consistent despite shifts in biotic interactions. Transfer accuracy may be improved by recent advances in the application of deep learning that provide greater flexibility and potentially

Microemulsion‐Based Drilling Fluids Incorporating Seashell Residue Powder: A Sustainable Approach to Fluid Loss Control

open access: yesJournal of Surfactants and Detergents, EarlyView.
Two microemulsion‐based drilling fluids incorporating SSRP were formulated using pine oil, the nonionic surfactant Alkonat L100W, and a glycerol/water solution. The results provide valuable insights into how surfactant‐assisted microemulsion systems can be engineered to enhance the performance and eco‐efficiency of drilling fluids.
