(Very) long‐term transport of Silurus glanis, Charcharhinus melanopterus, Scomb...

Correia, João; Daghfous, Gheylen; Silva, David; Graça, Gonçalo; Beltran, Ivan; Reis, João; Marques, José P.; Silva, Luís; Guedes, Rui; Morato, Telmo

In this paper, we cover 4 years of live fish transports that ranged from 14 to 200 h (8 days), and bioloads from 3.8 to 76.9 kg/m3. The key ingredients for success in all trips, where virtually no mortality occurred, was atributed to (1) pre‐buffering the water with sodium bicarbonate and sodium carbonate at 50 g/m3 (each)—and/or ATM Alka‐HaulTM at 25 g/m3—and applying additional (partial or full) doses through...

The multi-annual residency of juvenile smooth hammerhead shark in an oceanic is...

The increased risk of local extinction becomes critical for sharks depending on the narrow and isolated coastal habitats of oceanic islands. This includes large pelagic oceanic sharks that use such habitats as nurseries, as previously hypothesized for the smooth hammerhead Sphyrna zygaena, the least known of cosmopolitan large hammerhead sharks. We used a combination of acoustic and satellite telemetry in a juv...


‘Solo datasets’: unexpected behavioural patterns uncovered by acoustic monitori...

Baeyaert, Joffrey; Abecasis, David; Afonso, Pedro; Graça, Gonçalo; Erzini, Karim; Fontes, Jorge

A holistic understanding of the life-history strategies of marine populations is often hindered by complex population dynamics, exacerbated by an intricate movement ecology across their life history (Nathan et al. 2008; Parsons et al. 2008; Jeltsch et al. 2013). Movement patterns and spatial ecology can vary spatially and temporally for different reasons, mainly related to the organism’s life history and enviro...


Can Biofluids Metabolic Profiling Help to Improve Healthcare during Pregnancy?

Graça, Gonçalo; Diaz, Sílvia O.; Pinto, Joana; Barros, António S.; Duarte, Iola F.; Goodfellow, Brian J.; Galhano, Eulália; Pita, Cristina

This paper describes a metabonomics study of 2nd trimester biofluids (amniotic fluid, maternal urine, and blood plasma), in an attempt to correlate biofluid metabolic changes with suspected/diagnosed fetal malformations (FM) and chromosomal disorders as well as with later occurring gestational diabetes mellitus (GDM), preterm delivery (PTD), and premature rupture of membranes (PROM). The global biochemical pict...


NMR metabolomics of esca disease-affected vitis vinifera cv. Alvarinho leaves

Lima, Marta; Felgueiras, Mafalda; Graça, Gonçalo; Rodrigues, João; Barros, António; Gil, Ana M.; Dias, Alberto Carlos Pires

Esca is a destructive disease that affects vineyards leading to important losses in wine production. Information about the response of Vitis vinifera plants to this disease is scarce, particularly concerning changes in plant metabolism. In order to study the metabolic changes in Vitis plants affected by esca, leaves from both infected and non-affected cordons of V. vinifera cv. Alvarinho (collected in the Vinho...


Metabolite Profiling of Human Amniotic Fluid by Hyphenated Nuclear Magnetic Res...

Graça, Gonçalo; Duarte, Iola F.; Goodfellow, Brian J.; Carreira, Isabel M.; Couceiro, Ana Bela; Domingues, Maria do Rosário; Spraul, Manfred

The metabolic profiling of human amniotic fluid (HAF) is of potential interest for the diagnosis of disorders in the mother or the fetus. In order to build a comprehensive metabolite database for HAF, hyphenated NMR has been used, for the first time, for systematic HAF profiling. Experiments were carried out using reverse-phase (RP) and ion-exchange liquid chromatography (LC), in order to detect less and more p...
