Using two unique long-term\ndatasets we aim to evaluate whether species traits (body size, trophic\nlevel, dispersal capacity and habitat occupancy) can predict temporal\nvariations in the abundance of endemic, native non-endemic and exotic\narthropods in the Azores Islands. We found that body size is crucial to\npredict arthropods abundance trends. Small-bodied herbivorous arthropods\nshowed a decrease in abundance, while large-bodied indigenous arthropods\nincreased in abundance, mainly in well-preserved areas. Also,\nlarge-bodied exotic arthropods increased in abundance across the entire\narchipelago. Moreover, endemic canopy dwellers increased in abundance,\nwhile endemic ground-dwellers decreased in abundance. Simultaneously,\nexotic arthropods showed the opposite result, increasing abundance in\nthe ground while decreasing abundance in the canopy. Finally, habitat\ninfluenced both endemic and exotic spider abundance trends. Endemic\nspiders that occupy solely natural habitats experienced a decline in\nabundance, while exotic spiders in the same habitats increased in\nabundance. Our study underscores the significance of arthropod species\ntraits in predicting abundance changes in island ecosystems over time,\nas well as the importance of monitoring species communities.\nConservation efforts must extend beyond endangered species to protect\nnon-threatened ones, given the increased extinction risk faced by even\ncommon species on islands. Monitoring and restoration programs are\nessential for preserving island ecosystems and safeguarding endemic\narthropod populations.<\/jats:p>","DOI":"10.22541\/au.171714597.73460036\/v1","type":"posted-content","created":{"date-parts":[[2024,5,31]],"date-time":"2024-05-31T08:59:45Z","timestamp":1717145985000},"source":"Crossref","is-referenced-by-count":1,"title":["Arthropod traits as proxies for abundance trends in the Azorean Islands"],"prefix":"10.22541","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7332-9788","authenticated-orcid":true,"given":"Guilherme","family":"Oyarzabal","sequence":"first","affiliation":[{"name":"University of the Azores Faculty of Agrarian Sciences and the Environment"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8119-9960","authenticated-orcid":true,"given":"Pedro","family":"Cardoso","sequence":"additional","affiliation":[{"name":"Universidade de Lisboa Centre for Ecology Evolution and Environmental Changes"}]},{"given":"Fran\u00e7ois","family":"Rigal","sequence":"additional","affiliation":[{"name":"Universit\u00e9 de Pau et des Pays de l'Adour"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9087-091X","authenticated-orcid":true,"given":"M\u00e1rio","family":"Boieiro","sequence":"additional","affiliation":[{"name":"University of the Azores Faculty of Agrarian Sciences and the Environment"}]},{"given":"Ana M.
