Abstract: The Lactuca lineage is one of nine lineages in the lettuce subtribe (Cichorieae, Asteraceae) distributed in Europe, Africa, Asia and North America. Within the Lactuca lineage two clades show disjunct Eurasian-North American distributions. One disjunct clade consists of diploids (x = 8) and allotetraploids (x = 17), the former restricted t...

In the Azores Islands, two Euphrasia L. (Orobanchaceae) endemic species are recognized: Euphrasia azorica H.C.Watson, an annual herb, in Flores and Corvo, and Euphrasia grandiflora Hochst. ex Seub., a semi-shrub, in Pico, São Jorge and Terceira. Both species are highly endangered and protected by the Bern Convention and Habitats Directive. A popula...

The phylogenetic relationships and phylogeography of two relatively rare Macaronesian Lactuca species, Lactuca watsoniana (Azores) and L. palmensis (Canary Islands), were, until this date, unclear. Karyological information of the Azorean species was also unknown. For this study, a chromosome count was performed and L. watsoniana showed 2n = 34. A p...

Three Azorean endemic Ammi species were initially described: Ammi trifoliatum (Wats.) Trel., Ammi seubertianum (Wats.) Trel. and Ammi huntii (Wats.) Trel. Many taxonomic changes have been conducted, and one to three species have been considered. Two species are currently accepted: A. trifoliatum, which occurs in almost every island, and A. seuberti...

Full-text available
Island plants are frequently used as model systems in evolutionary biology to understand factors that might explain genetic diversity and population differentiation levels. Theory suggests that island plants should have lower levels of genetic diversity than their continental relatives, but this hypothesis has been rejected in several recent studie...
Conference Paper
Knowledge of the Azores flora has historically relied on the study of collections obtained during sporadic and brief visits conducted by collectors and naturalists coming from abroad. However, the far oceanic location of the Azores made it more inaccessible to these early studies than other Atlantic archipelagos, such as the Canary Islands and Made...
Article
Full-text available
Research dedicated to rare endemic plants is usually focused on one given aspect. However, holistic studies, addressing several key issues, might be more useful, supporting management programs, while unravelling basic knowledge about ecological and population level processes. A more comprehensive approach to research is proposed, encompassing: phyl...
Article
Full-text available
Lactuca watsoniana is an Azorean endemic plant, listed as a priority species for conservation. Although there is a considerable amount of data regarding germination in the genus Lactuca, little is known about seed germination in L. watsoniana, which is an important gap for defining conservation strategies. Seed viability (tetrazolium test) declined...
Article
Full-text available
Two endemic species of Leontodon are currently recognized in the Azores archipelago: Leontodon filii and L. rigens. However, there has been confusion regarding the application of these names and field observations and herbarium studies suggested three morphotypes in the islands. Here, we present a taxonomic revision of the Azorean endemic Leontodon...
Poster
While the number of Ammi native species (Apiaceae) occurring in Europe and the Mediterranean raises questions, the same happens with the Azores islands taxa. Initially, three endemic species where described: Ammi trifoliatum (Wats.) Trel., in Flores island, Ammi seubertianum (Wats.) Trel., in Pico and São Miguel islands and Ammi huntii (Wats.) Trel...

TALK: Lactuca watsoniana is an Azorean endemic plant, considered as a priority species for conservation. Although there is a considerable amount of data regarding germination in the genus Lactuca, little is known about seed germination in L. watsoniana, which is an important gap for defining conservation strategies. We tested the effects on seed g...

The genus Lactuca L., in its currently accepted circumscription, comprises about 230 species, distributed in Europe, Africa, Asia and North America. Lactuca watsoniana Trel. is a very rare, autotetraploid Azorean endemic plant, considered as a priority species for conservation, which occurs in São Miguel, Terceira, Pico and Faial, and is probably e...
Article
Full-text available
The genus Leontodon L. (Asteraceae) comprises approximately 50 species with a natural distribution area covering North America, Europe, northern Africa, and western Asia. Two of these species are endemic to the Azores Archipelago: Leontodon filii and Leontodon rigens. Although both species were targeted with several taxonomic revisions, so far no s...

Current projects aimed at the conservation of endemic species and restoration of native habitats require information about seed viability, held in a germplasm bank, and ex situ seed and plant production. In this study, we investigated: a) the viability of Spergularia azorica Lebel seeds after 18 years of storage, and the ability of the developed pl...

Lagoa do Canário is one of the most picturesque places in São Miguel Island (Azores, Portugal). Nevertheless, bryologists have not recorded much around its area, and it is suspected that the bryophyte inventory is incomplete. In this study, we present the list of bryophyte species historically gathered around Lagoa do Canário, as well as a field ac...
Conference Paper
This poster is related with the identification and evaluation of endemic, native and introduced vascular flora of Lombo Gordo. Therefore we tried to update the knowlwdge of the distribution of the variety of species found. The Lombo Gordo is a coastal area of ecological interest due to the diversity of biotopes encountered and the possibility of ob...
