The Portuguese housing market underwent major transformations between 2010 and 2020. Until then, a delicate but resentful stability had long existed, with distorted rent schemes and low annual price increases proportional to the national economy and the income of the Portuguese population. After the financial crisis, several internal and external variables converged to dramatically change this scenario. In recent years, a growing number of researchers have centred their attention on the difficulties that the Portuguese urban middle-class populations are facing in trying to find homes. This paper analyses these challenges and their impact quantitatively, focusing on the affordability of housing for purchase or rent and considering synthetic indicators for average household incomes in the Lisbon Metropolitan Area between the beginning of 2016 and the end of 2019. The results show that the cost of buying or renting a house in the main Portuguese urban system has become much more detached from local incomes. The article concludes with reflections on the structural reasons for the enduring inequalities in the housing markets and the difficulties recognising territorial cohesion and spatial justice as important elements shaping urban and housing policies in Portugal.
Five species of adult nematodes, unidentifiable nematode larvae, and three species of acanthocephalans, were found in freshwater ornamental fishes newly imported into Germany from Brazil, Colombia, Indonesia, Malaysia, Nigeria, Peru, Sri Lanka and Thailand. The following species were identified: Adult Nematoda: Pseudocapillaria tomentosa, Capillariidae gen. sp., Dichelyne hartwichi sp. n., Procamallanus (Spirocamallanus) pintoi and Spinitectus allaeri·, Acanlhocephala: Pseudogorgorhynchus arii gen. et sp. n., Neoechinorhynchus sp. and Pallisentis sp. The nematode Dichelyne hartwichi sp. n. (male only) from the intestine of Chelonodon fluviatilis (Hamilton) from Thailand is characterised mainly by the presence of minute cuticular spines on the tail tip, length of spicules (510 pm) and arrangement of caudal papillae. The acanthocephalan Pseudogorgorhynchus arii sp. n. from the intestine of Ariopsis seemanni (Günther) from Colombia represents a new genus Pseudogorgorhynchus gen. n., differing from other genera of the Rhadinorhynchidae mainly in possessing a small proboscis armed with markedly few (18) hooks arranged in six spiral rows. Spinitectus macheirus Boomker et Puylaert, 1994 and Spinitectus moraveci Boomker el Puylaert, 1994 are considered junior synonyms of Spinitectus allaeri Campana-Rouget, 1961
