The database we introduce is a pivotal component of the LIFE SNAILS project (Support and Naturalisation in Areas Importance for Land Snails). This initiative dedicated to safeguarding three endangered species terrestrial molluscs, specifically, two snails ( Oxychilus agostinhoi Martins 1981 Leptaxis minor Backhuys, 1975) semi-slug Plutonia angulosa (Morelet, 1860)), all which are single island endemics from Santa Maria Island face significant threats towards their populations. In this study, established comprehensive derived long-term arthropod monitoring campaign utilising SLAM (Sea, Land, Air, Malaise) traps. Although molluscs were not primary focus, our findings serve as credible proxy evaluating overall habitat quality endemic invertebrates, with arthropods serving principal indicators. From September December 2022, total 11 traps installed monitored monthly eleven sites mixed forests Island. Based on 33 available samples (11 x 3 sampling periods), recorded 118 taxa (of 94 identified at or subspecies level), belonging classes, 14 orders 62 families. taxa, 21 endemic, 31 native non-endemic, 32 introduced 10 indeterminate.

Essential Oils from Azorean Cryptomeria japonica Female Cones at Different Developmental Stages: Variations in the Yields and Chemical Compositions

Separations, Journal Year: 2024, Volume and Issue: 11(2), P. 62 - 62

Published: Feb. 18, 2024

Cryptomeria japonica (Thunb. ex L.f.) D. Don (Cupressaceae) is widely cultivated in the Azores archipelago (Portugal) for landscaping and timber production, generating a huge amount of biomass residues. Among these, female cones (FC) emerge as source particularly valuable essential oils (EOs), namely, promising broad-spectrum antimicrobial agents. However, phytochemical research on C. FC EOs remains scarce. This study evaluated EO yields chemical compositions immature mature (IFC MFC) from same batch Azorean japonica. IFC MFC EOs, obtained via hydrodistillation, presented different (0.72% vs. 1.12% w/w, dry weight), their composition, determined gas chromatography/mass spectroscopy, revealed that monoterpenes class was dominant (51.84% 69.13%), followed by sesquiterpenes (36.44% 26.28%) diterpenes (10.96% 3.03%) classes. correspondent oxygen-containing terpenes classes were 1.5–2.0 times higher IFC. Thus, maturation process an increase yield α-pinene content (19.5% 41.3%) but decrease other important bioactive terpenes/terpenoids (terpinen-4-ol, bornyl acetate, elemol, γ-eudesmol, phyllocladene, nezukol) content. In conclusion, due to unique may have differential commercial applications and, consequently, contribute increasing potential japonica’s industry.

The urgent need for conservation efforts in response to the global biodiversity crisis is exemplified by initiatives, such as EU LIFE BEETLES project. This project aims preserve endangered arthropod species that are crucial ecosystem functionality, with a focus on endemic beetle Flores, Pico and Terceira Islands (Azores, Portugal):
