“…As their present-day congeners, the large-shelled Persististrombus coronatus was probably an epifaunal herbivorous or detritivorous inhabitant of sandy and rocky shores covered by algae (Wells, 1998). As typical shallow-water species, the shells of these large strombids would be prone to be swept ashore post-mortem in large numbers by spring tides or storm events, as can be seen in the present times at Ponta Braço de Sirena (Sal Island, Cape Verde Archipelago; Zazo et al, 2010), or in the upper Pleistocene (MIS 5e) deposits at Matas Blancas (Fuerteventura Island, Canaries; Meco et al, 2002) and at La Marina, Alicante (East Spain) (Goy et al, 2006), where specimens of the congeneric P. latus occur in large numbers. However, at Santa Maria Island, no similar deposits were found, all P. coronatus specimens representing shells transported downslope into deeper marine environments, as at Pedra-quepica or at Baía de Nossa Senhora outcrops (Fig.…”

The family Strombidae is one of the twenty-three families and subfamilies of gastropods associated with tropical environmental conditions, and therefore useful as a biogeographical and palaeoclimatic proxy. Today, the strombid genus Persististrombus is represented in the NE Atlantic by a single species restricted to the tropical Mauritanian-Senegalese Province. This work reports the occurrence of Persististrombus coronatus from the lower Pliocene of Santa Maria Island in the Azores Archipelago. Based on this occurrence, and on the Mio-Pliocene fossil record of the NE Atlantic oceanic islands, palaeoclimatological considerations are discussed, which allow, for the first time, to include the Azores and the other Macaronesian islands in a wider context of the NE Atlantic palaeobiogeographical molluscan provinces. Late Miocene to present day molluscan biogeographic units, ranging in latitude from 60°N down to 17°S, are here defined and the boundaries of the proposed climatic zones are outlined. We suggest that during the upper Miocene-lower Pliocene, the palaeoclimate at Santa Maria Island was drastically different from that seen at those latitudes today, with mean annual sea surface temperatures (SST's) about 3.7°C to 6.3°C higher than the present-day 20.6°C, and with mean monthly SST's ranging from 20°C to 28°C, with six months with mean SST's over 24°C, conditions typical of a tropical setting.

“…One problem that has plagued studies of Quaternary marine deposits throughout the Mediterranean, as well as on European and African coastlines of the eastern Atlantic Ocean, is a lack of reliable ages. Going back half a century and continuing to this day, there has been a reliance on uranium-series ages of mollusks (Stearns andThurber, 1965, 1967;Bernat et al, 1978;Hearty, 1987;Causse et al, 1993;Hillaire-Marcel et al, 1986Zazo et al, 2002Zazo et al, , 2003Zazo et al, , 2007Zazo et al, , 2010Jedoui et al, 2003;Dubar et al, 2008). Despite an early conclusion that apparent ages derived from such analyses are not reliable (Kaufman et al, 1971), a more recent confirmation of this problem (Edwards et al, 2003), and periodic cautions about the hazards of apparent U-series ages of mollusks, specifically in the Mediterranean basin (Stearns, 1985;McLaren and Rowe, 1996;Meco et al, 2002;Mauz and Antonioli, 2009), there have been continued applications of U-series dating of mollusks or interpretations based on such data (Bardají et al, 2009;Zazo et al, 2010Zazo et al, , 2013Tuccimei et al, 2012;Vicens et al, 2012).…”

The emergent marine deposits of the Mediterranean basin have been recognized as an important record of Quaternary sea level history for more than a century. Previous workers identified what have been interpreted to be two separate high stands of sea in the late Quaternary, namely the "Eutyrrhenian" (thought to be ~ 120 ka) and the "Neotyrrhenian" (thought to be either ~ 100 ka or ~ 80 ka). On Mallorca, Spain, both of these named deposits lie close to present sea level, implying paleo-sea levels slightly above present during both marine isotope stages (MIS) 5.5/5e and either 5.3/5c or 5.1/5a. If these interpretations are correct, they conflict, at least in part, with sea level records from far-field localities.We analyzed corals from the Neotyrrhenian beds on Mallorca, which gave U-series ages from ~ 126 ka to ~ 118 ka. These ages are consistent with previously published amino acid data that show that the Neotyrrhenian and Eutyrrhenian deposits are not significantly different in age. A fossil molluscan fauna from the Neotyrrhenian deposits on Mallorca has a warm-water paleozoogeographic aspect, with nine southward-ranging species and four extralimital southern species. When compared with sea surface temperatures obtained from planktonic foraminifera and alkenones from ODP core 977 in the nearby Alboran Sea, the only time period that shows comparable warmth is MIS 5.5/5e, consistent with the U-series ages of corals from the Neotyrrhenian deposits. We propose that the Neotyrrhenian deposits are a beachrock facies of the same age as the Eutyrrhenian deposits. This interpretation is consistent with the differences in physical sedimentology of the two deposits, explains the U-series and amino acid data indicating the same age, is consistent with the very slight elevation difference of the Neotyrrhenian and Eutyrrhenian beds, and explains the similar, though not identical paleozoogeographic aspects of their fossil faunas.

“…In the continental shelf cores, dusts of terrestrial origin present a minimum concentration during the interglacial periods (higher vegetation cover) and the opposite during the glacial periods. In Cabo Verde Islands, such an oscillation is recorded in the alternation of calcrete (hot and arid conditions), sand dunes (dry and cold conditions), and paleosols (wetter periods) [67,68].…”

The Role of Climate and Topography in Shaping the Diversity of Plant Communities in Cabo Verde Islands

The flora and vegetation of the archipelago of Cabo Verde is dominated by Macaronesian, Mediterranean, and particularly by African tropical elements, resulting from its southernmost location, when compared to the other islands of the Macaronesia (i.e., Azores, Madeira, Selvagens, and Canary Islands). Very likely, such a geographical position entailed higher susceptibility to extreme climatic fluctuations, namely those associated with the West African Monsoon oscillations. These fluctuations led to a continuous aridification, which is a clear trend shown by most recent studies based on continental shelf cores. Promoting important environmental shifts, such climatic fluctuations are accepted as determinant to explain the current spatial distribution patterns of taxa, as well as the composition of the plant communities. In this paper, we present a comprehensive characterization of the main plant communities in Cabo Verde, and we discuss the role of the climatic and topoclimatic diversity in shaping the vegetation composition and distribution of this archipelago. Our study reveals a strong variation in the diversity of plant communities across elevation gradients and distinct patterns of richness among plant communities. Moreover, we present an overview of the biogeographical relationships of the Cabo Verde flora and vegetation with the other Macaronesian Islands and northwestern Africa. We discuss how the distribution of plant communities and genetic patterns found among most of the endemic lineages can be related to Africa’s ongoing aridification, exploring the impacts of a process that marks northern Africa from the Late Miocene until the present.
