Multiple pygmy blue whale acoustic populations in the Indian Ocean: whale song identifies a possible new population
Provedor de dados: 5
Autores: Leroy, Emmanuelle; Royer, Jean-yves; Alling, Abigail; Maslen, Ben; Rogers, Tracey L.
Blue whales were brought to the edge of extinction by commercial whaling in the twentieth century and their recovery rate in the Southern Hemisphere has been slow; they remain endangered. Blue whales, although the largest animals on Earth, are difficult to study in the Southern Hemisphere, thus their population structure, distribution and migration remain poorly known. Fortunately, blue whales produce powerful and stereotyped songs, which prove an effective clue for monitoring their different ‘acoustic populations.’ The DGD-Chagos song has been previously reported in the central Indian Ocean. A comparison of this song with the pygmy blue and Omura’s whale songs shows that the Chagos song are likely produced by a distinct previously unknown pygmy blue whale...

Investigating the microbial ecology of coastal hotspots of marine nitrogen fixation in the western North Atlantic
Provedor de dados: 5
Autores: Wang, Seaver; Tang, Weiyi; Delage, Erwan; Gifford, Scott; Whitby, Hannah; González, Aridane G.; Eveillard, Damien; Planquette, Helene; Cassar, Nicolas.
Variation in the microbial cycling of nutrients and carbon in the ocean is an emergent property of complex planktonic communities. While recent findings have considerably expanded our understanding of the diversity and distribution of nitrogen (N2) fixing marine diazotrophs, knowledge gaps remain regarding ecological interactions between diazotrophs and other community members. Using quantitative 16S and 18S V4 rDNA amplicon sequencing, we surveyed eukaryotic and prokaryotic microbial communities from samples collected in August 2016 and 2017 across the Western North Atlantic. Leveraging and significantly expanding an earlier published 2015 molecular dataset, we examined microbial community structure and ecological co-occurrence relationships associated...

Deciphering the molecular adaptation of the king scallop (Pecten maximus) to heat stress using transcriptomics and proteomics
Provedor de dados: 5
Autores: Artigaud, Sebastien; Richard, Joelle; Thorne, Michael A. S.; Lavaud, Romain; Flye-sainte-marie, Jonathan; Jean, Fred; Peck, Lloyd S.; Clark, Melody S.; Pichereau, Vianney.
Background: The capacity of marine species to survive chronic heat stress underpins their ability to survive warming oceans as a result of climate change. In this study RNA-Seq and 2-DE proteomics were employed to decipher the molecular response of the sub-tidal bivalve Pecten maximus, to elevated temperatures. Results: Individuals were maintained at three different temperatures (15, 21 and 25 degrees C) for 56 days, representing control conditions, maximum environmental temperature and extreme warming, with individuals sampled at seven time points. The scallops thrived at 21 degrees C, but suffered a reduction in condition at 25 degrees C. RNA-Seq analyses produced 26,064 assembled contigs, of which 531 were differentially expressed, with putative...

Marine biological research in Mozambique: past, present and future
Provedor de dados: 20
Autores: Paula, J.; Paula e Silva, R.; Hernroth, L.; Guissamulo, A.T.; Bandeira, S.O.; Gove, D.Z.; Macia, A.
This synopsis describes the development of marine biological research, including fisheries, in Mozambique. With around 3000 km of coastline, the living resources of the sea playa major role in the Mozambican society, mainly as a source of protein and income for the population, and of foreign revenue through exports. In the first years, after independence, in 1975, research activities in marine sciences were limited and mainly concentrated to fisheries through cooperation with Norway and the Soviet Union. A new era for biology started in 1985 when the Faculty of Biology at Universidade Eduardo Mondlane was re-opened. A 5yr curriculum towards a licentiate degree was introduced with a strong marine profile. Since the 1990s, a very dynamic de-velopment in...

National Report: Marine biodiversity in Kenya – the known and the unknown
Provedor de dados: 20
Autores: Fondo, E.
The Kenyan coastline is about 600 km in length and forms part of the western border of the Indian Ocean. It has an almost continuous fringing coral reef usually running parallel to the coast. Kenya’s territorial sea and Exclusive Economic Zone extend 12 nm and 200 nm respectively, with the total area of EEZ being 118 km2. The Kenyan coast runs in a southwesterly direction from the Somalian border in the north 1o41’S to 4o40’S at the border with Tanzania. Climate and weather systems on the Kenyan coast are dominated by the two distinct monsoon periods. From November to March, the north-east monsoon dominates and is comparatively dry. End of March to September the south-east monsoon dominates bringing heavy rains. Mean annual total rainfall ranges from 508...

National Report: The Marine Biodiversity of Mauritius
Provedor de dados: 20
Autores: Bhikajee, M.
The coastline of the island of Mauritius is 322 km long and is almost completely surrounded by fringing coral reefs enclosing a lagoon area totaling 243 km. The volcanic nature of the island's origin, the existence of coral reefs and the access to the lagoons of more than 50 rivers and rivulets, determine the diversity of the coastal habitats, flora and fauna. The island has several sandy beaches, protected bays and calm lagoons - factors that have favoured a prosperous tourism industry. Economically, the coastal zone is by far the most valuable segment of the Mauritian territory. Located here are the tourist facilities, secondary residences, ports, fisheries infrastructure and public beaches. Figure 3 gives the changes in coastal land distribution from...
