LIVRO DE RESUMOS DO X SIMPÓSIO IBÉRICO SOBRE A BACIA HIDROGRÁFICA DO RIO MINHO

ENVIRONMENTAL SMOKE (2021)

Carlos Antunes Cláudia Moreira Dimítri de Araújo Costa Ester Dias Fernando Cobo

O X Simpósio Ibérico Sobre a Bacia Hidrográfica do Rio Minho, organizado pelo Aquamuseu do Rio Minho/Câmara Municipal de Vila Nova de Cerveira e co-organizado pelo Centro Interdisciplinar de Investigação Marinha e Ambiental – Universidade do Porto, num contexto multidisciplinar, abordou temas que abrangeram áreas desde a geoquímica de sedimentos e formas erosivas do leito rochoso do rio Minho; as mudanças climáticas numa perspetiva da futura gestão da água e nos efeitos já evidentes ao nível das comunidades biológicas; importância da gestão dos recursos da pesca no rio Mouro pela monitorização e aplicação de regras específicas de exploração; diagnóstico e medidas em curso para a conservação das populações de peixes migradores; a ameaça dos poluentes emergentes; a divulgação de novos registos de invertebrados encontrados no rio Minho (abordagem taxonómica); evidências da colaboração entre pescadores e investigadores para um melhor conhecimento social da comunidade piscatória, da sua atividade e da sua contribuição para o processo de gestão; comunicação de ciência e educação ambiental. No âmbito da mesa-redonda (workshop), em modelo aberto à comunidade, onde participaram pescadores, foram apresentados resultados de trabalhos no âmbito do Conhecimento Ecológico Local (Etnobiologia), em que os próprios tiveram a oportunidade de manifestar as suas opiniões relacionadas com a atividade da pesca. Houve ainda oportunidade de entregar os prémios referentes ao concurso de ilustração científica “Rio Minho, Biodiversidade e Artes de Pesca”, cuja exposição completa esteve patente na Bienal de Cerveira.

Dataset of the complete mitogenome of the deep-sea sailfin roughshark, Oxynotus paradoxus Frade, 1929

Data in Brief (2023)

Ana Matos André Gomes‐dos‐Santos Sofia Graça Aranha Ester Dias Ana Veríssimo

Chondrichthyans comprise a diverse group of vertebrate species with extraordinary ecological relevance. Yet, multiple members of this evolutionary lineage are associated with significant extinction risk. The sailfin roughshark Oxynotus paradoxus is a deep-water benthic shark currently listed as vulnerable due to population declines in parts of its range. Here we provide the first complete mitochondrial genome of O. paradoxus, comprising also the first record for the genus and family Oxynotidae. These data can facilitate future monitoring of the genetic diversity in this and related species. Genomic DNA was extracted from O. paradoxus collected in the eastern North Atlantic off western Portugal (37.59°N, 9.51°W) and sent for Illumina Paired-End (2 × 150 bp) library construction and whole genome sequencing on a Novaseq6000 platform. Trimmomatic (version 0.38) was used to remove adapters and MitoZ (version 3.4) to assemble and annotate the mitogenome. This mitogenome with 17 100 bp has a total of 38 genes, 13 of which are protein-coding genes, 23 transfer RNA genes, and 2 ribosomal RNA genes. Eight transfer RNAs and 1 protein-coding gene (NADH dehydrogenase subunit 6, NAD6) are in the complementary strand. In the provided phylogenetic inference, with all available and verified Squalomorphii mitogenomes, the four orders are well separated, and as expected, O. paradoxus is placed in the Squaliformes order. This data reinforces the need for more genomic resources for the Oxynotidae family.

Benthic food webs support the production of sympatric flatfish larvae in estuarine nursery habitat

Fisheries Oceanography (2017)

Ester Dias Pedro Morais Ana M. Faria Carlos Antunes Joel C. Hoffman

Abstract Identifying nursery habitats is of paramount importance to define proper management and conservation strategies for flatfish species. Flatfish nursery studies usually report upon habitat occupation, but few attempted to quantify the importance of those habitats to larvae development. The reliance of two sympatric flatfish species larvae, the European flounder Platichthys flesus and the common sole Solea solea , on the estuarine food web (benthic versus pelagic), was determined through carbon and nitrogen stable isotope analysis. The organic matter sources supporting the production of P . flesus and S . solea larvae biomass originates chiefly in the benthic food web. However, these species have significantly different δ 13 C and δ 15 N values which suggest that they prey on organisms that use a different mixture of sources or assimilate different components from similar OM pools (or both).

Estuaries, A Happy Place For Fish

Frontiers for Young Minds (2021)

Pedro Morais Ester Dias

Anchovies, salmon, sardines, gobies, mullets, flounder, bass, barbels, eels, shad, and even sharks—what do they have in common? Well, at certain points in their lives you may find them in estuaries, the final sections of rivers before they meet the ocean. Some fish live in estuaries their entire lives. However, some fish species prefer living in the freshwater parts of estuaries, others only live close to the ocean, and a few others spread throughout the estuary. Some species prefer living close to the bottom, some in marshes, and some constantly swim around in the estuary. Some prefer eating other fish, while other species like worms, or insects, or microscopic animals. Unfortunately, many estuarine species are in danger, and all because of humans. In this article, we will tell you why estuaries are such special places for fish and describe some of the species that call the San Francisco Estuary their home.

Long-term monitoring of the fish community in the Minho Estuary (NW Iberian Peninsula)

Allan T. Souza Martina Ilarri Ester Dias Mário Jorge Araújo António Roleira

The paper presents an extensive fish sampling dataset spanning a long-term period (weekly) from 2010 to 2019. The data was collected in Lenta Marina, an upstream area in the Minho Estuary of the NW Iberian Peninsula. To capture fish, fyke nets were utilized as the sampling method. This dataset offers valuable insights into the abundance of each collected taxa, recorded per date. The dataset reports a comprehensive compilation of fish abundance data, providing a detailed record of how the fish community has changed over time. The dataset clearly shows a trend where the amount of fish from invasive taxa exceeds the count of fish from native taxa.

Long-term monitoring of the fish community in the Minho Estuary (NW Iberian Peninsula)

Zenodo (CERN European Organization for Nuclear Research) (2023)

Allan T. Souza Martina Ilarri Ester Dias Mário Jorge Araújo António Roleira

The dataset contains data from fyke nets deployed in the Minho Estuary (Portugal) from 2010 to 2019. The fyke nets were used for fish sampling and data collection. The sampling frequency varied but, on average, data was collected weekly using five different fyke nets. However, due to technical issues, the sampling pattern is not constant, with some fyke nets staying underwater for shorter or longer periods, and occasionally having fewer than five fyke nets per event. The dataset includes various variables such as eventID, eventDate, decimalLatitude, decimalLongitude, habitat, samplingProtocol, sampleSizeValue, sampleSizeUnit, organismQuantity, organismQuantityType, degreeOfEstablishment, scientificName, acceptedNameUsageID, taxonRank, kingdom, phylum, order, family, genus, and scientificNameAuthorship.

Allochthonous-derived organic matter subsidizes the food sources of estuarine jellyfish

Journal of Plankton Research (2017)

Pedro Morais Ester Dias Joana Cruz Paula Chainho Maria Manuel Angélico

Jellyfish modulate the energy fluxes between compartments of aquatic ecosystems and the period that energy remains within each compartment. However, the contribution of different sources of organic matter (OM) to the production of most estuarine jellyfish species is unknown. Therefore, this study aimed to identify and quantify the putative sources of OM for Blackfordia virginica (Cnidaria, Hydrozoa) Mayer, 1910 in two temperate estuaries, based on the analyses of carbon and nitrogen stable isotope ratios. Zooplankton was the main source of OM assimilated by B. virginica in both Mira and Guadiana estuaries. However, particulate organic matter (POM) also contributed to B. virginica biomass, up to 26 and 37% in Mira and Guadiana estuaries, respectively. The POM pool was apparently comprised by terrestrial-derived OM, as based on stable isotope ratios and C:NPOM. Terrestrial-derived OM is an undescribed carbon source for estuarine jellyfish. Our results support a working hypothesis stating that terrestrial-derived OM might support good physiological condition of B. virginica during periods of low metazooplankton abundance, through a detritus-based microbial food web transformation. Subsequent studies on trophic pathways ought to evaluate the temporal contribution of autochthonous and allochthonous OM and its consequences, accounting for the connectivity across ecosystems (terrestrial-estuarine-marine) and the interactions within compartments (pelagic-benthic).
