Nurse species facilitate persistence of dry forests in agricultural landscapes in Uruguay

open access: yesJournal of Vegetation Science, Volume 33, Issue 2, March/April 2022., 2022
Park forests form cultural landscapes of South America shaped by extensive cattle ranching in the transition between natural riverine forests and open grasslands. Tree regeneration, nurse–beneficiary interactions and community composition are analysed. Nurse trees facilitate recovery in grazed forests.

Using drones to reduce human disturbance while monitoring breeding status of an endangered raptor

open access: yesRemote Sensing in Ecology and Conservation, Volume 7, Issue 3, Page 550-561, September 2021., 2021
In birds, obtaining information related to nest occupancy, offspring status or breeding success is essential for population monitoring, particularly for species of conservation concern. Drones present an alternative to traditional climbing methods, but few studies have been done measuring their influence on birds’ behavior and reproductive success.

Microencapsulation Delivery System in Food Industry—Challenge and the Way Forward

open access: yesAdvances in Polymer Technology, Volume 2020, Issue 1, 2020., 2020
Microencapsulation is a promising technique, which provides core materials with protective barrier, good stability, controlled release, and targeting delivery. Compared with the pharmaceutical, cosmetic, and textile industries, food processing has higher requirements for safety and hygiene and calls for quality and nutrition maintenance.
