Cephalopod fauna of the Pacific Southern Ocean using Antarctic toothfish (Dissostichus mawsoni) as biological samplers and fisheries bycatch specimens
Publication . Queirós, J.P.; Ramos, J.A.; Cherel, Y.; Franzitta, M.; Duarte, B.; Rosa, R.; Monteiro, F.; Figueiredo, A.; Strugnel, J.M.; Fukuda, Y.; Stevens, D.W.; Xavier, J.C.
Cephalopods are an important component of Southern Ocean food webs but studies analysing their habitat and
trophic ecology are scarce. Here, we use the Antarctic toothfish Dissostichus mawsoni as a biological sampler of
Southern Ocean’s cephalopods in the Ross, Amundsen, and D’Urville Seas. Ten cephalopod taxa were identified
in the diet of the Antarctic toothfish, with Pareledone turqueti and Moroteuthopsis longimana being the only species
present in all the three studied areas. DNA analysis conducted on squid flesh samples allowed identification of
eight and two specimens of Mesonychoteuthis hamiltoni and M. longimana, respectively, proving this technique as a
potential tool to improve the knowledge of cephalopods biodiversity and biogeography in the Southern Ocean.
Stable isotopes were used to compare the habitat (δ13C) and trophic ecology (δ15N) between two life-stages of the
two most abundant squid species (M. longimana and Psychroteuthis glacialis) from the D’Urville Sea (both squid
species) and Amundsen Sea (only P. glacialis). Higher δ13C values in M. longimana suggest that this species inhabits
waters near the Antarctic Polar Front, with incursions into sub-Antarctic waters, whilst P. glacialis spends
its entire life in Antarctic waters. The most recently deposited part of the beak is enriched in 15N suggesting an
increase in trophic level during squid growth. These results give us the first insights into the bathyal distribution
of cephalopods in the Amundsen and D’Urville Seas, as well as into the ontogenetic changes of two of the most
consumed squid species by top predators in this region. Such results are an important step towards improving the
biogeography of Antarctic cephalopods, being of utmost importance to understand the biodiversity, food web
structure, and functioning of this region
Mechanisms implemented for the sustainable development of agriculture: an overview of Cabo Verde performance
Publication . Varela, Danilson; Monteiro, Filipa; Vidigal, Patrícia; Silva, Luís; Romeiras, Maria M.
In 2005, the Economic Community ofWest African States (ECOWAS) adopted the Common
Agricultural Policy of ECOWAS (ECOWAP), as an instrument for implementing the Comprehensive
Africa Agriculture Development Program (CAADP). The main goals of ECOWAP/CAADP were
set to promote agriculture development and end hunger by 2025. In this study we focused on the
Cabo Verde archipelago as one of the best performing countries within ECOWAS in terms of overall
sustainable development. In this paper, the evolution of the ECOWAP implementation and of the
Sustainable Development Goals (SDGs) associated with agriculture in Cabo Verde, were assessed by
semi-quantitative (e.g., agricultural policies, agrarian periodical literature) and quantitative (modeling
regression of ECOWAP implementation and Sustainable Development Goals—SDGs—performance)
analyses. Our integrated results suggest that the agriculture development strategies, the signature of
ECOWAP/CAADP by the national government, and political stability might explain the progress
made towards poverty reduction and the improvement of food security. The results also show that
agriculture-related SDGs in Cabo Verde are higher than the mean values obtained from the remaining
West African countries, well above the top 25% WA countries. Nevertheless, Cabo Verde public
expenditure into agriculture under the ECOWAP was generally below the targeted 10% of the national
budget, with food import required to meet internal food demands
