Seed removal decrease by invasive Argentine ants in a high Nature Value farmland
Wendt, Clara Frasconi; Nunes, Alice; Dias, Sara Lobo; Verble, Robin; Branquinho, Cristina; Boieiro, MárioSeed dispersal by ants is an important ecological process that maintains the structure and diversity of natural communities, however, it is vulnerable to biological invasions. Argentine ants are one of the worst invasive ant species and cause severe changes in ecosystem processes and native ant biodiversity declines in invaded sites. Here, we studied seed removal by ants combining observations and a cafeteria e...

Ant functional structure and diversity changes along a post-grazing succession ...
Wendt, Clara Frasconi; Nunes, Alice; Köbel, Melanie; Verble, Robin; Matos, Paula; Boieiro, Mário; Branquinho, CristinaGrazing exclusion may be used to promote the recovery of disturbed ecosystems. A promising way for the evaluation of its effectiveness is through the monitoring of key biological groups, particularly those more responsive to disturbance and playing key roles in ecosystem functioning. Ants have been used as ecological indicators as they are abundant, diverse and sensitive to environmental changes. Here, we aimed...
Local environmental variables are key drivers of ant taxonomic and functional b...
Wendt, Clara Frasconi; Ceia-Hasse, Ana; Nunes, Alice; Verble, Robin; Santini, Giacomo; Boieiro, Mário; Branquinho, CristinaThe decomposition of beta-diversity (β-diversity) into its replacement (βrepl) and richness (βrich) components in combination with a taxonomic and functional approach, may help to identify processes driving community composition along environmental gradients. We aimed to understand which abiotic and spatial variables influence ant β-diversity and identify which processes may drive ant β-diversity patterns in Me...

Using a space-for-time approach to select the best biodiversity-based indicator...
Wendt, Clara Frasconi; Nunes, Alice; Verble, Robin; Santini, Giacomo; Boieiro, Mário; Branquinho, CristinaMediterranean drylands are particularly vulnerable to predicted increases in aridity which are expected to have negative consequences for biodiversity. To understand the effects of climate change on ecosystems, a framework for the selection of indicators based on the essential biodiversity variables (EBV) was proposed. In this framework, a functional approach has been suggested because functional traits have sh...
