Influence of the Azores high on sea level pressure and wind, and on precipitation, in the Eastern Tropical Pacific Ocean [PDF]

open access: yes, 1966
ENGLISH: Intensification of the Azores high pressure cell in mid-year, with concomitant air flow from the Caribbean into the Pacific, is shown to be responsible for a secondary minimum of precipitation observed along the tropical Pacific coast of the ...

Differential temporal beta‐diversity patterns of native and non‐native arthropod species in a fragmented native forest landscape [PDF]

open access: yes, 2018
An important factor that hinders the management of non‐native species is a general lack of information regarding the biogeography of non‐natives, and, in particular, their rates of turnover.

An improved phylogeny and revised taxonomy of Catillariaceae (Lecanoromycetes, Ascomycota)

open access: yesTAXON, EarlyView.
Abstract The boundaries of the family Catillariaceae have largely remained untested through phylogenetic methods. Recent studies have led to the transfer of several genera previously classified in Catillariaceae to the newly described family Leprocaulaceae. Despite these changes, the distinction between Catillariaceae, Leprocaulaceae, and Catinariaceae

Mantle dynamics and volcanism emplacement in the Azores [PDF]

open access: yes, 2012
The Azores plateau is a triangular shaped topographic feature encompassing the boundary zone where three major tectonic plates (EU, NU and NA) meet. The eastern side of the plateau is delimited by two major tectonic discontinuities: the Mid Atlantic ...

Extreme rainfall in Madeira: the June 2023 weather event

open access: yesWeather, EarlyView.
This study investigates the meteorological conditions behind the extreme precipitation event on 6 June 2023 over Madeira Island, Portugal. The event set a national daily record of 497.5mm and was unusual for occurring in early summer, as most extremes in the region occur in winter.

Mechanical and toxicological effects of deep-sea mining sediment plumes on a habitat-forming cold-water octocoral

open access: yesFrontiers in Marine Science, 2022
Deep-sea mining activities are expected to impact deep-sea biota through the generation of sediment plumes that disperse across vast areas of the ocean. Benthic sessile suspension-feeding fauna, such as cold-water corals, may be particularly susceptible ...

Short term effects of irradiance on the growth of Pterocladiella capillacea (Gelidiales, Rhodophyta) [PDF]

open access: yes, 2019
Pterocladiella capillacea has been economically exploited for agar extraction in the Azores for many years. Harvesting dropped to a full stop in the early 1990s due to a population collapse, but restarted in 2013.
