Desvendar a complexidade das florestas: como o LiDAR e os drones estão a transf...
Lhoumeau, Sébastien; Elias, Rui B.; Seidel, Dominik; Gabriel, Rosalina; Borges, Paulo A. V.As florestas estão entre os ecossistemas mais complexos e vitais da Terra. Ao manter a biodiversidade, as florestas asseguram a resiliência e a estabilidade dos ecossistemas, oferecendo serviços essenciais. Desempenham também um papel fundamental na regulação do clima global através do seu papel no ciclo do carbono.
Unveiling Arthropod Responses to Climate Change: A Functional Trait Analysis in...
Wallon, Sophie; Rigal, François; Melo, Catarina; Elias, Rui B.; Borges, Paulo A. V.This study investigates the impact of elevated temperatures on arthropod communities in intensively managed pastures on the volcanic island of Terceira, Azores (Portugal), using a functional trait approach. Open Top Chambers (OTCs) were employed to simulate increased temperatures, and the functional traits of ground dwelling arthropods were analyzed along a small elevation gradient (180–400 m) during winter and...
Microsatellites reveal high levels of genetic admixture in the natural populati...
Rego, Rúben; Vieira, Ângela F.; Silva, Luís; Elias, Rui B.; Silva, Carlos; Resendes, Roberto; Moura, MónicaLaurus (Lauraceae) species are currently restricted to isolated refugia in the southern Black Sea, Mediterranean Basin, southern Morocco, and Macaronesian archipelagos. One to three species of Laurus has been recognized: the Azorean endemic Laurus azorica, L. nobilis from the Mediterranean, and L. novocanariensis from Madeira and the Canary Islands. This study aims to determine the population structure, genetic...
In defence of the entity of Macaronesia as a biogeographical region
Fernández‐Palacios, José María; Otto, Rüdiger; Capelo, Jorge; Caujapé‐Castells, Juli; De Nascimento, Lea; Duarte, Maria Cristina; Elias, Rui B.Since its coinage ca. 1850 AD by Philip Barker Webb, the biogeographical region of Macaronesia, consisting of the North Atlantic volcanic archipelagos of the Azores, Madeira with the tiny Selvagens, the Canaries and Cabo Verde, and for some authors different continental coastal strips, has been under dispute. Herein, after a brief introduction on the terminology and purpose of regionalism, we recover the origin...
Arceuthobium Species (Viscaceae) Parasitizing an Angiosperm: The Unique Case of...
Elias, Rui B.; Moura, Mónica; Roxo, Guilherme; Borges Silva, L; Pavão, Diogo C.; Resendes, Roberto; Pereira, Fernando; Nickrent, DanielArceuthobium azoricum Wiens & Hawksw. is a rare Azorean endemic epiphytic hemiparasite (mistletoe), which typically parasitizes branches of the gymnosperm Juniperus brevifolia (Hochst. ex Seub.) Antoine (Cupressaceae), which is also an Azorean endemic. Here, we describe a population of A. azoricum, on Pico Island, parasitizing Erica azorica Hochst. ex Seub. (Ericaceae), which is also an Azorean endemic. Our mol...
Original plant diversity and ecosystems of a small, remote oceanic island (Corv...
Connor, Simon E.; Lewis, Tara; van Leeuwen, Jacqueline F.N.; van der Knaap, W.O. (Pim); Schaefer, Hanno; Porch, Nicholas; Gomes, Ana I.Remote islands harbour many endemic species and unique ecosystems. They are also some of the world's most human-impacted systems. It is essential to understand how island species and ecosystems behaved prior to major anthropogenic disruption as a basis for their conservation. This research aims to reconstruct the original, pre-colonial biodiversity of a remote oceanic island to understand the scale of past exti...
Biodiversity inventory of the Protected Area for the Management of Habitats or ...
Aguiar Sousa, Mariana; Romão, Joana; Lamelas-López, Lucas; Elias, Rui B.; Gabriel, Rosalina; Borges, Paulo A. V.; Martins, Bruna; Roxo, JoanaThe data presented in this study comprises a collection of observations documented within the frame of the LIFE IP Azores Natura project (2019-2027) in the Azores archipelago. The primary goal of this project is to implement conservation measures on both land and sea, with the aim of enhancing the conservation status of species and habitats covered by the Birds and Habitats Directives. For the documentation of ...
A multitaxa approach to biodiversity inventory in Matela protected area (Tercei...
Aguiar Sousa, Mariana; Lamelas-López, Lucas; Elias, Rui B.; Gabriel, Rosalina; Borges, Paulo A. V.Background This manuscript is the first contribution of the project, “Matela – uma ilha de biodiversidade” (“Matela - an island of biodiversity”), that aims to restore the native vegetation within the Azorean Protected Area of the Terceira Island Nature Park known as the "Protected Area for the Management of Habitats or Species of Matela" (TER08), situated on Terceira Island, the Azores Archipelago, Portugal. T...

Possíveis impactes das alterações climáticas nas pastagens dos Açores
Elias, Rui B.; Melo Drumonde, Catarina; Wallon, Sophie; Maduro Dias, Cristiana; Borba, Alfredo E. S.; Madruga, João; Borges, Paulo A. V.Este livro apresenta os principais resultados do projeto PASTURCLIM, que decorreu em três pastagens da ilha Terceira. Recorrendo a câmaras de topo aberto (CTA), o objetivo foi simular o aumento da temperatura previsto durante este século, como resultado do aquecimento global, e avaliar os efeitos: (1) Na produtividade das pastagens, na qualidade da forragem e na disponibilidade de nutrientes do solo; (2) Na com...
