Preserving Agricultural Diversity
Gonçalves, Elsa M.; Silva, Mafalda; Lageiro, Manuela; Roseiro, Luísa Cristina; Soares, Andreia; Ramos, Cristina; Mendes, MárciaThe conservation and characterisation of traditional apple cultivars are essential for safeguarding agrobiodiversity and supporting regional economies. Reineta de Fontanelas, a long-established cultivar from the Saloia region of Sintra, Portugal, remains insufficiently described despite its cultural relevance. This study provides the first integrated characterisation of Reineta de Fontanelas apples collected fr...
New pollen taxon Syncolpraedapollis angolensis nov. gen. sp. nov.: A noteworthy...
Mendes, Márcia; Pereira, Zélia; Rodrigues, Cristina F.A.; Nsungani, Nsungani, P.C.ABSTRACT: A palynostratigraphic study of the upper Cunga and lower Quifangondo deposits in the Cabo de São Brás section, Kwanza Basin, Angola, has revealed a new pollen named Syncolpraedapollis angolensis nov. gen. sp. nov. This finding was part of a wider survey in the upper Cunga and lower Quifangondo deposits of the Cabo de São Brás section, Kwanza Basin, Angola, covering the latest Eocene to the latest Olig...

Pereira, H. J. R.; Lopes, Francisco; Pérez-Cano, J.; Santos, Vanda Faria dos; Malafaia, Elisabete; Mendes, Márcia; Pereira, Zélia; Sweetman, Steven C.ABSTRACT: Over a century after Paul Choffat's initial description of the Arrifes section, a pioneering figure in Portuguese geology who highlighted the vertical arrangement of the strata and the occurrence of a limestone bed containing a copious quantity of orbitolinid tests, this upper Barremian–lower Aptian stratigraphic succession, which is fully exposed along a coastal cliff section located 2.5 km west-sout...
The age and depositional environments of the lower Karoo Moatize Coalfield of M...
Fernandes, Paulo; Hancox, J.; Mendes, Márcia; Pereira, Zélia; Lopes, Gilda; Marques, João; Jorge, Raul CG Santos; Albardeiro, LuísABSTRACT: The Moatize Coalfield belongs to a network of continental Karoo basins of central Mozambique, known as the Zambezi Basin. Palynological and sedimentological studies were performed on four coal exploration boreholes to determine the age, depositional settings, and overall geological evolution of its extensive coal deposits. Clastic formations recognised in this coalfield, in ascending order, are the Vú...

Palynology of the Albian–Turonian sediments from the Sumbe region, Kwanza Basin...
Rodrigues, Cristina F.A.; Mendes, Márcia; Pereira, Zélia; Nsungani, P.C.; Fernandes, Paulo; Duarte, L. V.; Chitangueleca, Belarmino; Sebastião, LumenABSTRACT: Palynological investigations in the Sumbe region of the Kwanza Basin, Angola, have identified Albian to Turonian assemblages in four sections of the Quissonde Facies of the Mucanzo, Cabo Ledo, and Itombe formations. These studies aimed to determine their biostratigraphic ages and infer paleoenvironmental, paleoclimatic, and paleogeographic models. The presence of Odontochitina costata, Palaeohystricho...
Late Famennian (latest Strunian) palynomorph assemblages and their role in the ...
Mendes, Márcia; Pereira, Zélia; Matos, João Xavier; Albardeiro, Luis; Morais, Igor; Araújo, VitorABSTRACT: This research examines palynomorph assemblages preserved in sediments of the Iberian Pyrite Belt (IPB) that host the Neves-Corvo massive sulfide deposit and its importance for mineral exploration. The sediments belong to the Neves Formation, characterized by black shales and minor occurrences of siltstones and cherts, indicative of reduced environmental conditions, favorable to sulfide deposition in a...
