Fragilaria odeloucaensis E.Morales, Novais, C.E.Wetzel, Ector & Morais sp. nov. (LM: Figs 2–19, SEM: Figs20–31) Description:—Frustules rectangular in girdle view, frequently heterovalvar with respect to striation (Figs 17–19). Valves lanceolate with capitate apices (Figs 2–16). Length: 17.9–28.3µm, width: 3.6–4.3 µm (n = 40). Axial area narrow and straight under LM (Figs 2–16), zig-zagged under SEM (Figs 20–25), delimited by elevated virgae that barely extend over sternum and by depressed striae (Figs 20, 21, 24). Axial area depressed in outer view (Figs 20–25), but raised in inner view (Figs 27–29), though this latter feature is less noticeable in valves with sparser striation (Fig. 26). Striae uniseriate, alternate and parallel in the middle of the valve (Figs 20, 21, 24), becoming slightly curved and radiate toward the apices (Figs 22, 23, 25). Stria density 11–16 in 10 µm. Each stria continues up to 1/2–2/3 of the valve mantle (Figs 27–29, 30, 31). Striae clearly depressed in outer and inner views (Figs 20–25, 27–29), though less depressed in internal views of valves with sparser striation (Fig. 26). Areolae round to elliptic (Figs 20–29), 6–7 in 1 µm. Volae small, growing from the internal contour of the areola (Figs 24, 31, black arrow heads). Spines absent. Virgae raised with respect to axial area and striae in outer view (Figs 20–25), also raised in internal view (Figs 27–29), although this feature is less prominent in inner view in valves with sparser striation. Central area with clear one-sided, square-shaped fascia infrequent, ghost striae faint, but clearer on valve face edges of the fascia (e.g. Figs 2, 5, 6, 8, 14). Blister-like depositions present along the abvalvar edge of mantle, irregular in shape and larger at the apices (Figs 30, 31, black wavy arrows). A single rimoportula present at one apex, oblique to apical axis of valve, with elliptic to squarish outer opening, aligned with a stria (Figs 20–22, white arrows), and parallel, raised, convex labia attenuated at the ends (Figs 26–28, white arrows). Apical pore fields well-developed, of the ocellulimbus type, composed of several rows of round pores entirely located on the apical valve mantle, externally framed by bulged borders (apical pore field is sunken) (Figs 20–23, 25, 31). Cingulum composed of several open elements (Figs 23, 30, 31, black arrows), perforated by a single row of round pores (Figs 22, 23, white arrow heads). Plastids unknown. Type:— PORTUGAL. Algarve region, Monchique Council: Odelouca Stream, epilithon, sampling point in the stream, 37º 21’ 19.87” N, 8º 26’ 27.80” W, Josué Figueira, 20th March 2017 (holotype BR-4723 = Fig. 2). Etymology:—The species epithet makes reference to the stream where the new taxon was found, the Odelouca (“ode” Arabic fem. for river, Portuguese “louca” and Arabic “lawqa” fem. for mad, insane). Ecology and distribution:—The sampling site is located in a deep vee valley without natural terraces. The 500 m stretch was characterized by earth (crumbly) and bedrock in the banks, the channel substrate was mainly composed by cobble, gravel/pebble, the flow types were rippled, smooth and unbroken standing waves, there were some special features in the channel as exposed boulders, one unvegetated and two vegetated mid-channel bars, and the vegetation in the channel was composed by submerged broad-leaved plants, liverworts/moss/lichens, emergent reeds/sedges/ rushes/grasses/horsetails and filamentous algae. The land-use within 5 m of the banktops included broadleaf/mixed plantations and scrub & shrubs, and within 50 m of the banktop consisted of Eucalyptus plantation mixed with shrubs and herbaceous plants, the vegetation structure within 1 m of the banktops and in the bank faces was composed of two or three vegetation types, there was a semi-continuous extent of trees in the margins, the reach is also located 100 m downhill from a main road. The stretch was characterized by a banktop 1.5 m in height, a bank to bank width of 8 m, a 10 m wide bankfull channel, and a 7 m wide water cover in the channel. The Odelouca Stream is a temporary river that dries out completely at the end of the summer and is classified within the Mountainous Rivers in the South, according to the Water Framework Directive typology. At the time of sampling, there was flowing water with a velocity of 0.46 m ∙ s-1 at the riffle where the scrubbed cobbles were collected. Depth of the transparent flowing water was 8 cm, water temperature was 14.1 ºC (at 12:00 AM), pH 7.2, electrical conductivity 161.1 μS∙ cm-1, and dissolved oxygen 90.1 % sat., 9.2 mg O ∙L- 1. At this site, the stream was classified as 2 Excellent (IPS = 17.8, EQR = 0.96 since the reference value for this typology is 18.5). Thus far, the presence of the new species was confirmed at Odelouca Stream (in this manuscript) and in epilithon of St. Pedro Stream (St. Pedro de Muel locality in the Ribeiras do Oeste hydrographic basin in the Center Region of Portugal), where it was collected in June 10th 2007 (Novais 2011, reported as Fragilaria sp. 2.). St. Pedro Stream is a permanent watercourse in a small watershed (ca. 38 km 2). The sampling site is located 13.1 km from the source, and at the sampling time the water temperature was 16.4 ºC, conductivity was 495.0 µS/cm, pH 7.5, dissolved oxygen 61.7 % sat, 6.13 mg ∙L- 1, alkalinity 73.0 mg CaCO 3 ∙L- 1, ammonium 0.003 mg N∙L- 1, chlorides 45 mg Cl- ∙L- 1, total organic carbon 20.8 mg C∙L- 1, phosphates 0.006 mg P∙L- 1, total phosphorus 0.025 mg P∙L- 1, nitrates 1.5 mg N∙L- 1, nitrites 0.015 mg N∙L- 1, sulphates 60.1 mg SO 4 ∙L- 1, total suspended solids 2.2 mg ∙L- 1, and a turbidity of 1.1 NTU. Accompanying flora:—The new taxon reached a relative abundance of 5.2 % in the type slide. The most abundant accompanying species were Achnanthidium minutissimum (Kützing) Czarnecki (1994: 157; 36.4 % relative abundance), Fragilaria gracilis Østrup (1910: 190; 18.8 %), Gomphonema truncatum Ehrenberg (1832: 88; 6.8 %), Brachysira microcephala (Grunow) Compère (1986: 26, 28; 5.9 %), Gomphonema tergestinum (Grunow) Fricke in A.W.F.

Temporary streams represent ca. half of the river network at the worldwide level, and in regions such as southern Europe their dominance of the landscape is evident (Larned et al. 2010, McDonough et al. 2011, Barbosa et al. 2020). Currently, these streams are receiving increased attention due to their importance as high diversity spots for algae, arthropods, plants, etc., and due to the ecosystem services they provide (Acuña et al. 2014, Datry et al. 2018b). Because of their geographical position and the land use changes in their watersheds (increased urbanization, agriculture, etc.), climate change, contamination and habitat fragmentation constitute forces threatening their integrity and ecological characteristics (Datry et al. 2018a, Bonada et al. 2020).

Nowadays, the Mediterranean freshwater systems face the threat of water scarcity, along with multiple other stressors (e.g., organic and inorganic contamination, geomorphological alterations, invasive species), leading to the impairment of their ecosystem services. All these stressors have been speeding up, due to climate variability and land cover/land use changes, turning them into a big challenge for the water management plans. The present study analyses the physicochemical and phytoplankton biomass (chlorophyll-a) dynamics of a large reservoir, in the Mediterranean region (Alqueva reservoir, Southern Portugal), under diverse meteorological conditions and land cover/land use real scenarios (2017 and 2018). The most important stressors were identified and the necessary tools and information for a more effective management plan were provided. Changes in these parameters were further related to the observed variations in the meteorological conditions and in the land cover/land use. The increase in nutrients and ions in the water column, and of potentially toxic metals in the sediment, were more obvious in periods of severe drought. Further, the enhancement of nutrients concentrations, potentially caused by the intensification of agricultural activities, may indicate an increased risk of water eutrophication. The results highlight that a holistic approach is essential for a better water resources management strategy info:eu-repo/semantics/publishedVersion

Orientadora: Profa. Dra. Luciana Zaterka Dissertação (mestrado) - Universidade Federal do ABC, Programa de Pós-Graduação em Filosofia, São Bernardo do Campo, 2020. A associação do conceito nietzschiano de além-do-homem com o trans-humanismo tornou-se tema de acirradas discussões internacionais. Com o intuito de ir além da polêmica, esta dissertação adotou como objetivo analisar as possibilidades da adoção da ética do além-do-homem como alternativa ao trans-humano. Inicialmente, levantou-se a hipótese de que ambos os conceitos são distintos, têm bases valorativas diferentes, sendo que o primeiro pode ser alternativa desejável ao segundo. Na análise conceitual do trans-humanismo, utilizou-se como ponto de partida a obra A História do Pensamento Trans-Humanista, de Nick Bostrom, e Trans-Humanismo: a busca tecnológica do melhoramento humano, de Antonio Diéguez. Estas colocaram em evidência as variáveis valorativas intrínsecas ao conceito: o cientificismo e a melhoria do humano. Foram analisadas, então, as relações do pensamento trans-humanista com o Positivismo de Auguste Comte, com o evolucionismo de Charles Darwin e o com o eugenismo de Francis Galton. Posteriormente, ao abordar a filosofia de Nietzsche, principalmente na fase madura de sua produção, foi examinado o conceito de vontade de potência, que apresenta o homem como criador de valores, a ciência moderna como expressão de decadência, o niilismo como processo histórico de criação e destruição de valores, o além-do-homem como possibilidade aberta ao homem superior empenhado em tornar-se quem é, aceitando a vida com seus obstáculos e suas dores. Foi possível constatar que o além-do-homem como alternativa ao trans-humanismo, exige a criação de uma gaia ciência, a aceitação do sofrimento e da dor como via privilegiada e indispensável do tornar-se quem se é e de superação de si. Embora sejam filosofias divergentes e diante do avanço irreversível do desenvolvimento tecnocientífico, a filosofia de Nietzsche ainda se mostra um caminho interessante de reflexão frente ao trans-humanismo, pois aponta, sobretudo, para possibilidades emancipatórias. The association of the Nietzschean concept of beyond-man with transhumanism has become the subject of intense international discussions. In order to go beyond the controversy, this dissertation has the objective of analyze the possibilities of adopting the ethics of the beyond-man as an alternative to the trans-human. Initially, it was assumed that both concepts are distinct, have different valuation bases, the former being a desirable alternative to the latter. In the conceptual analysis of transhumanism, The History of Transhumanist Thought, by Nick Bostrom, and Transhumanism: the technological search for human enhancement, by Antonio Diéguez, was taken as a starting point. These highlighted the valuing variables intrinsic to the concept: scientism and human improvement. Were analyzed the relations of transhumanism with the Auguste Comte's Positivism, Charles Darwin's evolutionism and Francis Galton's eugenics. Subsequently, addressing Nietzsche's philosophy, in the mature phase of production, the concept of the will to power was analyzed, which puts man as a creator of values, modern science as an expression of decadence, nihilism as a historical process of creation and destruction of values, the beyond-man as a possibility open to the superior man committed to becoming who he is, accepting life with its obstacles and pains. It was possible to verify that the beyond-man as an alternative to transhumanism, requires the creation of a gay science, the acceptance of suffering and pain as a privileged and indispensable way of becoming who one is and of overcoming oneself. Although they are divergent philosophies and given the irreversible advance of technoscientific development, Nietzsche's philosophy still shows an interesting way of reflection in face of transhumanism, for, above all, points to emancipatory possibilities.
