Arthropod traits as proxies for abundance trends in the Azorean Islands
Oyarzabal, Guilherme; Cardoso, Pedro; Rigal, François; Boieiro, Mário; Santos, Ana M. C.; Amorim, Isabel R.; Malumbres‐Olarte, Jagoba; Costa, RicardoHuman 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...
Standardised inventories of spiders (Arachnida, Araneae) of Macaronesia III: dr...
Crespo, Luís Carlos; Cardoso, Pedro; Malumbres-Olarte, Jagoba; Pereira, Fernando; Romeiras, Maria; Ros-Prieto, Alejandra; Rigal, FrançoisBackground With this publication, we contribute to the knowledge of the arachnofauna of Cabo Verde, focusing specifically on the Islands of Santo Antão and São Vicente. Data were obtained from samples collected as part of the project "Macaronesian Islands as a testing ground to assess biodiversity drivers at multiple scales" (FCT - MACDIV, 2015-2018). This project aimed to identify the factors influencing commu...
Building a Portuguese coalition for biodiversity genomics
Marques, João P.; Alves, Paulo C.; Amorim, Isabel R.; Lopes, Ricardo Jorge; Moura, Monica; Myers, Eugene; Sim-Sim, Maria; Sousa-Santos, CarlaThe diverse physiography of the Portuguese land and marine territory, spanning from continental Europe to the Atlantic archipelagos, has made it an important repository of biodiversity throughout the Pleistocene glacial cycles, leading to a remarkable diversity of species and ecosystems. This rich biodiversity is under threat from anthropogenic drivers, such as climate change, invasive species, land use changes...
Surveying Cory Shearwater colonies with camera traps and identifying potential ...
Lamelas-López, Lucas; Borges, P.A.V.Background The Azores holds the largest population of Cory's shearwater Calonectris borealis (Cory, 1881) (Aves, Procellariiformes, Procellariidae) in the world. One of the major threats of this species in the Azores is the predation by invasive mammals, which were introduced during European colonisation of the islands. The present study provides a dataset from a camera-trapping survey performed in colonies of ...
Biological Integrity of Azorean Native Forests Is Better Measured in Cold Season
Tsafack, Noelline; Lhoumeau, Sébastien; Ros Prieto, Alejandra; Navarro, Loic; Kocsis, Timea; Manso, Sónia; Martins Figueiredo, TelmaABSTRACT: The Azorean archipelago, recognized as one of the world’s biodiversity hotspots, is home to a diverse and unique community of arthropod species, highlighting a notable degree of endemism. However, the native forests that support these species are facing significant degradation due to habitat loss and fragmentation. In this study, we aimed to determine the ideal season for measuring the biological integ...
Inventory of tiger- and ground-beetles (Coleoptera, Caraboidea, Cicindelidae an...
Serrano, Artur; Baptista, Martim; Carvalho, Rui; Boieiro, Mário; Mendes, Sara; Bartz, Marie; Timóteo, Sérgio; Azevedo-Pereira, Henrique; Aguiar, CarlosBackground The Gorongosa National Park (Mozambique) is one of the most emblematic protected areas in Africa, well known for its vertebrate biodiversity and restoration ecology efforts following the Mozambican civil war in 1992. The invertebrate biodiversity of Gorongosa National Park is still poorly studied, although the scarce information available indicates the existence of a rich number of species, namely in...
Temperature variation in caves and its significance for subterranean ecosystems
Medina, Maria J.; Antić, Dragan; Borges, P.A.V.; Borko, Špela; Fišer, Cene; Lauritzen, Stein-Erik; Martín, Jose L.; Oromí, Pedro; Pavlek, MartinaClimate change affects all ecosystems, but subterranean ecosystems are repeatedly neglected from political and public agendas. Cave habitats are home to unknown and endangered species, with low trait variability and intrinsic vulnerability to recover from human-induced disturbances. We studied the annual variability and cyclicity of temperatures in caves vis-à-vis surface in different climatic areas. We hypothe...
Island spider origins show complex vertical stratification patterns in Macaronesia
Costa, R.; Cardoso, Pedro; Rigal, F.; Borges, P.A.V.Spiders are among the most diverse and yet threatened groups of arthropods in Macaronesia. Found in most habitat types, they occupy the vertical gradient of native forests from ground to canopy level. We hypothesize that their vertical distribution is influenced by the colonization origin. As introduced species should arrive using shipping containers and similar means, they should mostly occupy the lower levels...
Dispersal syndromes are poorly associated with climatic niche differences in th...
Leo, María; Steinbauer, Manuel J.; Borges, P.A.V.; Azevedo, Eduardo B.; Gabriel, Rosalina; Schaefer, Hanno; Santos, Ana M. C.Aim: Environmental niche tracking is linked to the species ability to disperse. While well investigated on large spatial scales, dispersal constraints also influence small-scale processes and may explain the difference between the potential and the realized niche of species at small scales. Here we test whether niche size and niche fill differ systematically according to dispersal syndrome within isolated ocean...
Stone-Stacking as a Looming Threat to Rock-Dwelling Biodiversity
Rocha, Ricardo; Borges, P.A.V.; Cardoso, Pedro; Mirza Dika, Kusrini; Martín-Esquivel, José Luis; Mota-Ferreira, Mário; Nunes, Sara F.; Orfão, InêsThis letter to the editor describes the surge of “photo-friendly” stacks of stones as an emerging tourism-associated threat to rock-dwelling biodiversity.
