Plausible causes of seed preferences and diet composition in seed‐eating passerines

Journal of Avian Biology, Volume 2022, Issue 3, March 2022., 2022
We evaluated whether seed mass, handling time, handling efficiency and profitability account for (a) preferences in controlled experiments and (b) field‐diet composition of four bird species of the Monte desert, Argentina. The question of whether birds maximise their energy intake rates while feeding on seeds is assessed.

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

Journal 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.

Biology, host specificity and DNA barcoding of cryptic Eueupithecia species (Lepidoptera: Geometridae), and implications for biological control of Parkinsonia aculeata (Fabaceae) in Australia

Austral Entomology, Volume 61, Issue 1, Page 124-132, February 2022., 2022
Abstract Parkinsonia aculeata L. (Fabaceae: Caesalpinioideae), native to the Americas, is a designated Weed of National Significance in Australia. The leaf‐feeding geometrid moth species, Eueupithecia cisplatensis Prout (Lepidoptera: Geometridae), was identified as a potential biological control agent of P.

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

Remote 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

Advances 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.
