The Azorean archipelago, recognized as one of the world’s biodiversity hotspots, is home to a diverse and unique community arthropod species, highlighting notable degree endemism. However, native forests that support these species are facing significant degradation due habitat loss fragmentation. In this study, we aimed determine ideal season for measuring biological integrity forest sites using index (IBI) based on communities captured with Sea, Land, Air Malaise (SLAM) traps. Drawing more than thirty years research experience in forests, selected twelve reference sites, six representing preserved disturbed forest, compared how IBI values vary between seasons. exhibited consistent variations seasons indicating areas can be conducted at any time year without specific seasonal preference. contrast, differences were observed pristine winter combination spring data (cold semester) showing notably higher other semesters. This finding suggests best optimized cold seasons, while detection exotic impact most effective summer autumn. Consequently, if resources limited, monitoring efforts should concentrated obtain maximum minimum IBI, respectively. Additionally, our study optimal detect potentially invasive species.

In the summer of 2024, a study was conducted on Terceira Island in Azores Archipelago, Portugal, aiming to characterise vertical diversity and spatial distribution patterns arthropods within native exotic forest ecosystems. This forms part broader research initiative designed investigate how alterations habitat structure influence complexity stability arthropod food webs Azorean habitats. By systematically sampling across multiple strata —from floor canopy aimed generate detailed insights into ecological dynamics governing biodiversity species interactions. Results from this monitoring will contribute significantly understanding impacts composition management strategies, ultimately providing information for conservation planning restoration efforts at preserving resilience island The current dataset comprises identified terrestrial collected using SLAM (Sea, Land Air Malaise) traps Pitfall diverse strata. A total 32,797 specimens were Arachnida, Diplopoda, Chilopoda Insecta classes. 18,372 (56%) or subspecies level, including 12,745 adults 5,627 juveniles taxa, such as Araneae Hemiptera due availability reliable identification methods. resulting encompasses 150 11 subspecies, distributed 21 orders, 81 families 148 genera. emerged most abundant order, with 7,697 recorded Coleoptera stood taxonomically diverse, encompassing 19 distinct 50 sub-species. ten comprise predominantly endemic non-endemic species, two detected amongst them. comprehensive serves significant augmentation existing baseline knowledge concerning arthropods, thereby facilitating formulation future long-term comparisons. It offers valuable abundance both forests Azores.

Human activities drive ecological transformation, impacting island ecosystems from species diversity to traits, mainly through habitat degradation and invasive species. Using two unique long-term datasets we aim evaluate whether traits (body size, trophic level, dispersal capacity occupancy) can predict temporal variations in the abundance of endemic, native non-endemic exotic arthropods Azores Islands. We found that body size is crucial trends. Small-bodied herbivorous showed a decrease abundance, while large-bodied indigenous increased well-preserved areas. Also, across entire archipelago. Moreover, endemic canopy dwellers ground-dwellers decreased abundance. Simultaneously, opposite result, increasing ground decreasing canopy. Finally, influenced both spider Endemic spiders occupy solely natural habitats experienced decline same Our study underscores significance arthropod predicting changes over time, as well importance monitoring communities. Conservation efforts must extend beyond endangered protect non-threatened ones, given extinction risk faced by even common on islands. Monitoring restoration programs are essential for preserving safeguarding populations.
