The BALA project: A pioneering monitoring of Azorean forest invertebrates over ...

Globally, 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...

New findings of terrestrial arthropods from the Azorean Islands

The knowledge on taxonomic diversity of arthropods is key to better understanding the biodiversity patterns and processes and guiding sustainable conservation strategies and practices. In the Azores, terrestrial arthropods are relatively well-inventoried following the publication of comprehensive checklists that have been regularly updated. Nevertheless, every year, new species are found as a result of new arri...

Arthropod traits as proxies for abundance trends in the Azorean Islands

Human 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...

Festa do Bioblitz Açores 2023: tantas espécies que vivem no Jardim!

No passado dia 17 de junho de 2023 a Terceira, conhecida entre os açorianos como a ilha festeira, recebeu novamente a festa do bioblitz – BioBlitz Açores 2023. Tal como no primeiro BioBlitz Açores em 2019, o Jardim Duque da Terceira em Angra do Heroísmo foi o local escolhido para a realização desta cada vez mais conhecida atividade de ciência cidadã: “cidadãos comuns” sem formação formal em ciência, orientados ...

Côa Valley’s medicinal plants as potential cosmetic ingredients: cytotoxic and ...

Côa Valley is a Northeast region of Portugal, classified as a UNESCO World Her- itage Site since 1998, and recognised as “the most important open-air Paleo- lithic rock art site”. So far, little is known about the natural endogenous resourc- es of this territory, namely medicinal plants. According to a preliminary ethnobotanical survey in this region, several medicinal plants were mentioned to have skin-benefic...

Island spider origins show complex vertical stratification patterns in Macaronesia

1.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. 2. 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 l...

Festa do Bioblitz Açores: a diversidade dos artrópodes do Jardim Duque da Terce...

Como detalhamos em um outro artigo deste mesmo volume do Pingo de Lava, o BioBlitz Açores 2023 foi um sucesso educativo, lúdico e científico, com o registo de 188 espécies de líquenes, plantas, aves e artrópodes (Amorim et al., 2023). Como é habitual neste tipo de atividades de ciência cidadã ou participativa, os artrópodes foram o grupo melhor representado (86 espécies). Devido aos seus valores de biodiversida...
