Toumeyella parvicornis versus endotherapic abamectin: three techniques, 1 year after

Pest Management Science, Volume 79, Issue 10, Page 3676-3680, October 2023., 2023
Comparing three different abamectin endotherapic techniques. Results showed similar long‐term effects in reducing adult females of Toumeyella parvicornis affecting Pinus pinea. Only one technique showed differences with the untreated control and abamectin traces inside the plants 14 months after the insecticide injection. Abstract Background Toumeyella

On the relative importance of resource availability and habitat connectivity as drivers of soil biodiversity in Mediterranean ecosystems

Journal of Ecology, Volume 111, Issue 7, Page 1455-1467, July 2023., 2023
The authors provide a comprehensive assessment of the response of key members of the soil food web to habitat fragmentation and tree die‐off (landscape level plant–soil interactions), illustrating the major role of soil carbon, habitat connectivity, and tree die‐off in driving soil biodiversity and trophic structure.

Mussel parasite richness and risk of extinction

Conservation Biology, Volume 36, Issue 6, December 2022., 2022
Abstract Parasite conservation is important for the maintenance of ecosystem diversity and function. Conserving parasites relies first on understanding parasite biodiversity and second on estimating the extinction risk to that biodiversity. Although steps have been taken independently in both these areas, previous studies have overwhelmingly focused on

Conceptual design and cost analysis of a large‐scale plant for converting red mud into building materials

International Journal of Ceramic Engineering &Science, Volume 3, Issue 6, Page 279-286, November 2021., 2021
Abstract The high level of sodium in red mud (RM) is one of the main issues hindering its incorporation as a raw material for construction and building materials. This paper presents a few studies on building materials developed using more than 70% w/w RM content.
