Global homogenization of biota is underway through worldwide introduction and establishment of non-indigenous (exotic) species. Organisms fouling ship hulls are continually in transit and can affect communities through biodiversity loss and serious damage to economy and public health. In the Azores, for the first time, underwater alien species prospection(More)
The Azores archipelago was selected as a case study since there are few studies on macroalgae introduction in oceanic islands. While at a global scale, around 3 % of macroalgae are considered non-indigenous; in the remote oceanic islands of the Azores, over 6 % of the marine algal flora is non-indigenous. The taxa distribution pattern of non-indigenous(More)
BACKGROUND Evaluations are essential to judge the success of public health programmes. In Europe, the proportion of public health programmes that undergo evaluation remains unclear. The European Centre for Disease Prevention and Control sought to determine the frequency of evaluations amongst European national public health programmes by using national hand(More)
The rainfall regime in southern Portugal is clearly Mediterranean. In such regions, the research on space-time patterns of extreme precipitation is an important contribution to assess desertification dynamics, among other impact studies applications. For the space-time interpolation and uncertainty assessment of an extreme precipitation index, in the(More)
This study provides the first description of the larval development of the commercially exploited barnacle Megabalanus azoricus. It describes the changes in larval size and shape as well as the general morphology and duration of each larval stage. Embryos were obtained from gravid specimens collected at São Miguel Island and reared through six naupliar(More)
The homogenization and analysis of long-term meteorological data sets are currently of unprecedented interest to the scientific community. If the monitoring station network is dense enough, many techniques use data from nearby stations ('reference' stations) in order to account for regional climate changes and to isolate the effects of irregularities in a(More)
The occurrence of Paracerceis sculpta (Holmes, 1904) in the Macaronesia biogeographical region is reported for the first time. This isopod, native from the northeastern Pacific region, has probably been transported as hull fouling, hiding in either niche areas of vessels or associated with fouling bryozoans. Specimens of P. sculpta were collected from(More)
The present study reports for the first time the occurrence of Caprella scaura in the remote oceanic islands of the Azores archipelago. Caprella scaura is a widespread caprellid with an invasive potential and a complicated taxonomy due to the existence of individuals that vary morphologically between and within regions. Caprella scaura specimens collected(More)
Subfossil biotic assemblages in lakes’ surface sediments have been used to infer ecological conditions across environmental gradients. Local variables are usually the major drivers of assemblage composition, but in remote oceanic islands biogeographic filters may play a significant role. To assess the contribution of local and regional filters in the(More)
