The drivers of plant turnover change across spatial scales in the Azores
Leo, María; Rigal, François; Ronquillo, Cristina; Borges, Paulo A. V.; Azevedo, Eduardo Brito; Santos, Ana M. C.Beta diversity patterns are essential for understanding how biological communities are structured. Geographical and environmental factors, as well as species dispersal ability, are important drivers of beta diversity, but their relative importance may vary across spatial scales. In this study, we evaluate whether beta diversity changes across geographical scales and analyse how different drivers affect turnover...
The BALA project: A pioneering monitoring of Azorean forest invertebrates over ...
Pozsgai, Gabor; Lhoumeau, Sébastien; Rosário, Isabel Amorim Do; Boieiro, Mário; Cardoso, Pedro; Costa, Ricardo; Ferreira, Maria Teresa; Leite, AbrãoGlobally, there is a concerning decline in many insect populations, and this trend likely extends to all arthropods, potentially impacting unique island biota. Native non-endemic and endemic species on islands are under threat due to habitat destruction, with the introduction of exotic, and potentially invasive, species, further contributing to this decline. While long-term studies of plants and vertebrate faun...
Arthropod traits as proxies for abundance trends in the Azorean Islands
Oyarzabal, Guilherme; Cardoso, Pedro; Rigal, François; Boieiro, Mário; Santos, Ana M. C.; Amorim do Rosário, Isabel; Malumbres-Olarte, JagobaHuman activities drive ecological transformation, impacting island ecosystems from species diversity to ecological traits, mainly through habitat degradation and invasive species. Using two unique long-term datasets we aim to evaluate whether species traits (body size, trophic level, dispersal capacity and habitat occupancy) can predict temporal variations in the abundance of endemic, indigenous (endemic and na...

A trait‐based framework for dung beetle functional ecology
deCastro‐Arrazola, Indradatta; Andrew, Nigel R.; Berg, Matty P.; Curtsdotter, Alva; Lumaret, Jean‐Pierre; Menéndez, Rosa; Moretti, MarcoTraits are key for understanding the environmental responses and ecological roles of organisms. Trait approaches to functional ecology are well established for plants, whereas consistent frameworks for animal groups are less developed. Here we suggest a framework for the study of the functional ecology of animals from a trait-based response–effect approach, using dung beetles as model system. Dung beetles are a...
Global systematic map of research on bats in agricultural systems
Xavier, Bruna Silva; Rainho, Ana; Santos, Ana M. C.; Vieira, Marcus Vinícius; Carvalho, William DouglasIntroduction: The conversion of natural habitats to agricultural systems is one of the main global threats to bats. Here, we aimed to develop a systematic mapping to identify publication trends and research gaps in studying bats and agricultural systems. Methods: We reviewed 309 studies published between 1990 and 2021 that sampled bats in agricultural systems or evaluated the effect of these systems on these an...
Dung removal increases under higher dung beetle functional diversity regardless...
Noriega, Jorge Ari; Hortal, Joaquín; deCastro-Arrazola, Indradatta; Alves-Martins, Fernanda; Ortega, Jean C. G.; Bini, Luis Mauricio; Andrew, Nigel R.Dung removal by macrofauna such as dung beetles is an important process for nutrient cycling in pasturelands. Intensification of farming practices generally reduces species and functional diversity of terrestrial invertebrates, which may negatively affect ecosystem services. Here, we investigate the effects of cattle-grazing intensification on dung removal by dung beetles in field experiments replicated in 38 p...
Geographical shifts in the successional dynamics of inland dune shrub communities
Chozas, Sergio; Chefaoui, Rosa M.; Correia, Otília; Santos, Ana M. C.; Hortal, JoaquínSpecies' environmental requirements and large-scale spatial and evolutionary processes determine the structure and composition of local communities. However, ecological interactions also have major effects on community assembly at landscape and local scales. We evaluate whether two xerophytic shrub communities occurring in SW Portugal follow constrained ecological assembly dynamics throughout large geographical...

Lhoumeau, Sébastien; Cardoso, Pedro; Boieiro, Mário; Ros-Prieto, Alejandra; Costa, Ricardo; Lamelas-López, Lucas; Leite, AbrãoBACKGROUND: A long-term study monitoring arthropods (Arthropoda) is being conducted since 2012 in the forests of Azorean Islands. Named "SLAM - Long Term Ecological Study of the Impacts of Climate Change in the natural forest of Azores", this project aims to understand the impact of biodiversity erosion drivers in the distribution, abundance and diversity of Azorean arthropods. The current dataset represents ar...

Lhoumeau, Sébastien; Cardoso, Pedro; Costa, Ricardo; Boieiro, Mário; Malumbres-Olarte, Jagoba; Rosário, Isabel Amorim do; Rigal, FrançoisBACKGROUND: Long-term studies are key to understand the drivers of biodiversity erosion, such as land-use change and habitat degradation, climate change, invasive species or pollution. The long-term project SLAM (Long Term Ecological Study of the Impacts of Climate Change in the natural forest of Azores) started in 2012 and focuses on arthropod monitoring, using SLAM (Sea, Land and Air Malaise) traps, aiming to...
