The native biodiversity of oceanic islands is threatened by human-driven disturbance and the growing number species introductions which often interfere with natural ecological processes. Here, we aim to evaluate effect anthropogenic on plant-pollinator interactions in forest communities an island (Terceira, Azores, Portugal). We found that predominated preserved sites compared disturbed ones extant were mostly dominated generalist species. Dipterans, particularly hoverflies, emerged as primary flower visitors, while introduced hymenopterans (Apis mellifera Bombus terrestris) beetles locally important, respectively, sites. Human-driven seems be responsible for observed differences abundance composition between drive changes specific network metrics (namely nestedness, interaction strength asymmetry, specialization), one study areas. Our findings also suggest provide opportunities can facilitate establishment through their broad networks.

Azorean biodiversity is relatively well-known following important scientific contributions during the last three decades. These have set a comprehensive species checklist for Archipelago, improved significantly knowledge on abundance, ecology and distribution contributed to define priorities conservation management research. Nevertheless, despite these efforts, key functional group - pollinators remains poorly known in Azores, including their occurrence different habitat-types islands. Insect play ecological role valuable ecosystem service being crucial having basic information good status of populations, if we aim ensure long-term sustainability terrestrial ecosystems. Furthermore, island ecosystems are facing significant pressures from land-use climatic changes and, increasing arrival alien remote areas, presenting pressing need assess effects factors pollination. Here, present an inventory pollinator found Terceira along gradient disturbance encompassing 30 sites distributed throughout island. We identified 2547 40 taxa, mostly dipterans hymenopterans recorded novel associations. A high number taxa native species, endemics, but 14 Archipelago. The use combination standardised sampling techniques allowed us collect diverse groups, but, most importantly, data collected will contribute impacts human activities abundance richness support decision-making habitat Azores.

The data presented here is part of a doctoral project aimed at characterising and comparing arthropod diversity across biotic communities in coastal ecosystems. present work provides an inventory the arthropods recorded two grasslands ecosystems: Portugal mainland Azores. Sampling was conducted on São Miguel Island (Azores Archipelago) as well Sesimbra Sines regions (Setúbal District, Portugal). Thirty-one plots were set visited four times, spring summer 2022. specimens collected sorted catalogued into total 534 species morphospecies. In total, 67 common to both A 13,515 counted grasslands. We registered three new records for Azores (in Island), all being exotic: Aritranisdirector (Thumberg, 1822) (Hymenoptera, Ichneumonidae), Draeculacephalabradleyi, Van Duzee, 1915 (Hemiptera, Cicadellidae) Isodontia sp. Patton, 1880 Sphecidae). This publication demonstrates importance reservoirs some potentially invasive species.
