Considering Other Consumers: Fisheries, Predators, and Atlantic Herring in the Gulf of Maine
Provedor de dados: 7
Autores: Read, Andrew J; Duke University; aread@duke.edu; Brownstein, Carrie R; Duke University; cbrownstein@audubon.org.
After decades of overexploitation and severe depletion, Atlantic herring stocks in waters of the northeastern United States have recovered. Fishery managers now consider the herring resource to be underexploited. Nevertheless, some fishery managers and sustainable fishery advocates in New England have expressed concern that the fishery management plan may not adequately consider the importance of herring as prey for marine mammals, seabirds, and piscivorous fish. Several studies suggest that consumption by these predators is significant, yet trophic interactions are not explicitly considered in stock assessment models. Instead, as in most fisheries stock assessments, predation is subsumed within the natural mortality rate, and no empirical estimates of...

Autores: Albouy, Camille; Delattre, Valentine L.; Merigot, Bastien; Meynard, Christine N.; Leprieur, Fabien.
Aim Identifying the multifaceted biodiversity hotspots for marine mammals and their spatial overlap with human threats at the global scale. Location World-wide. Methods We compiled a functional trait database for 121 species of marine mammals characterized by 14 functional traits grouped into five categories. We estimated marine mammal species richness (SR) as well as functional (FD) and phylogenetic diversity (PD) per grid cell (1° × 1°) using the FRic index (a measure of trait diversity as the volume of functional space occupied by the species present in an assemblage) and the PD index (the amount of evolutionary history represented by a set of species), respectively. Finally, we assessed the spatial congruence of these three facets of biodiversity...

Trace element levels in foetus-mother pairs of short-beaked common dolphins (Delphinus delphis) stranded along the French coasts
Provedor de dados: 5
Autores: Lahaye, V; Bustamante, Paco; Dabin, W; Churlaud, C; Caurant, Florence.
Tissues of foetus-mother pairs of common dolphins (Delphinus delphis) stranded along the French coasts (Bay of Biscay and English Channel) were analysed for their Cd, Cu, Hg, Se and Zn contents. In the kidneys, foetal Cd levels were extremely low, and strong relationships between Cu and Zn suggested the involvement of metallothioneins since early foetal life. The results also indicated a limited maternal transfer of Hg during pregnancy since levels in the tissues of foetuses were below 1 mu g g(-1) w.wt. However, hepatic Hg levels in foetuses increased with body length, and were also proportionate to maternal hepatic, renal and muscular Hg levels. Lastly, affinities between Hg and Se in tissues would participate in Hg neutralisation in both mothers-through...

Monitoring the impact of litter in large vertebrates in the Mediterranean Sea within the European Marine Strategy Framework Directive (MSFD): constraints, specificities and recommendations
Provedor de dados: 5
Autores: Galgani, Francois; Claro, F.; Depledge, M.; Fossi, C.
In its decision (2010/477/EU) relating to the European Marine Strategy Framework Directive (MSFD, 2008/56/EC), the European Commission identified the following points as focuses for monitoring:  (i) 10.1.1: Trends in the amount, source and composition of litter washed ashore and/or deposited on coastlines,  (ii) 10.1.2: Trends in the amount and composition of litter in the water column and accumulation on the sea floor,  (iii) 10.1.3: Trends in the amount, distribution and composition of micro-particles (mainly microplastics), and  (iv) 10.2.1 Trends in the amount and composition of litter ingested by marine animals.  Monitoring the impacts of litter will be considered further in 2014. At that time, the strategy will be discussed in the context of the...

Let's go beyond taxonomy in diet description: testing a trait-based approach to prey-predator relationships
Provedor de dados: 5
Autores: Spitz, Jerome; Ridoux, Vincent; Brind'Amour, Anik.
1.  Understanding ‘Why a prey is a prey for a given predator?’ can be facilitated through trait-based approaches that identify linkages between prey and predator morphological and ecological characteristics and highlight key functions involved in prey selection.  2.  Enhanced understanding of the functional relationships between predators and their prey is now essential to go beyond the traditional taxonomic framework of dietary studies and to improve our knowledge of ecosystem functioning for wildlife conservation and management. 3.  We test the relevance of a three-matrix approach in foraging ecology among a marine mammal community in the northeast Atlantic to identify the key functional traits shaping prey selection processes regardless of the taxonomy...

Modelling of the sound field radiated by multibeam echosounders for acoustical impact assessment
Provedor de dados: 5
Autores: Lurton, Xavier.
Multi-Beam Echo-Sounders (MBES) designed for seafloor-mapping applications are today a major tool for ocean exploration and monitoring. Concerns have been raised about their impact towards marine life and especially marine mammals, although their inherent characteristics (high frequencies, short signals and narrow transmitting lobes) actually minimize this possibility. The present paper proposes an analysis of MBES radiation characteristics (pulse design, source level and radiation directivity pattern) accounting for the various geometries met today and expressed according to the metrics used for acoustical impact assessment (maximum Sound Pressure Level, and cumulative Sound Exposure Level). A detailed radiation model is proposed, including the...

Contamination par les organochlorés des dauphins de Commerson des îles Kerguelen
Provedor de dados: 5
Autores: Abarnou, Alain; Robineau, Daniel; Michel, Pierre.
Top predators like marine mammals have been intensively used for monitoring the contamination of the marine environment, particularly in industrialized coastal areas of the Northern Atlantic Ocean. Such data concerning contamination in the Southern hemisphere are very scarce. Samples were taken in the fatty protuberance of the forehead (melon) from eleven Commerson's dolphins (Cephalorhynchus commersonii, Lacépède, 1804) caught in the coastal waters of the Kerguelen Islands (Southern Indian Ocean). They were analyzed for DDT, PCB and HCB, using capillary gaz chromatography. The levels of contamination [DDT= 1 150 ± 650, PCB = 1 150 ± 770, HCB=500±300ng/g of extracted matter (lipids)] are between ten and a hundred times Jess than those found in similar...

Selected trace elements (Cd, Cu, Hg, Se, Zn) were measured in the kidneys and the liver of 104 harbour porpoises (Phocoena phocoena) stranded along the coasts of France, Galicia (Spain), Ireland, Scotland (UK), and the Netherlands. Generally, relatively low concentrations of toxic elements were encountered in the tissues of European porpoises, except for two individuals, which displayed high hepatic Hg concentrations. Also, elevated Cd levels obtained in Scottish porpoises could be related to their feeding preferences and this result suggests an increase of the proportion of cephalopods in their diet with latitude. Moreover, significant geographical differences were seen in hepatic Zn concentrations; the elevated Zn concentrations displayed by porpoises...

Captures accidentelles françaises de mammifères marins sur les filets calés en Manche-mer du Nord et en zones Ciem VII. Observations réalisées durant les deux années du projet FilManCet ainsi que dans le cadre d’Obsmer
Provedor de dados: 5
Autores: Morizur, Yvon; Gaudou, Olivier; Miossec, Dominique; Toulhoat, Lucile; Gamblin, Caroline.
Up to now there has been no strong investigation on by-catch of marine mammals in the French set net fisheries of the English Channel (ICES areas VIIe,d &amp; IVc) as the EC 812/2004 Regulation does not oblige the state members to put observers on board of vessels in the ICES area VII. A study named FilManCet has been started end 2008-beginning 2009 to focus on the by-catch occurring on the set net vessels (whatever the hull length is) issued from Boulogne and Dunkerque ports (fisheries in VIId&amp;IVc) and also from several ports of North of Brittany. In this study which is conducted by the Fishing Industry, the data are made available to the scientists of Ifremer who has prepared also the sampling scheme for observation at sea. Two observers are employed...

Ecological and biological factors controlling the concentrations of trace elements (As, Cd, Cu, Hg, Se, Zn) in delphinids Globicephala melas from the North Atlantic Ocean
Provedor de dados: 5
Autores: Caurant, Florence; Amiard, Jean-claude; Amiard-triquet, Claude; Sauriau, Pierre-guy.
Trace elements (As, Cd, Cu, Hg, Se and Zn) were determined in liver and kidney of pilot whales Globicephala melas Traill, 1809 collected from 7 schools caught at different seasons around the Faroe Islands. These and other biological data at our disposal enabled us to confirm and to define more accurately the relations shown previously between age, sex and trace element concentrations in marine mammals. The most striking features were: (1) the elevated levels of Cd and Hg in pilot whales compared to other marine mammals and to minimum adverse-effect levels established for humans; (2) the biocumulative behaviour of Cd and Hg; (3) the high correlations between Hg and Se, predominantly influenced by age; and (4) the high correlations between Cd and Zn, the...

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...

An ecosystem approach for the assessment of fisheries impacts on marine top predators: the Bay of Biscay case study
Provedor de dados: 5
Autores: Lassalle, Geraldine; Gascuel, Didier; Le Loch, Francois; Lobry, Jeremy; Pierce, Graham John; Ridoux, Vincent; Santos, Maria Begona; Spitz, Jerome; Niquil, Nathalie.
A number of marine mammal populations is currently threatened by their interactions with fisheries. The present study aimed to provide insights into the severity of potential impacts of operational and biological interactions between top predators and fisheries, in the Bay of Biscay region. Our approach was to modify an Ecopath with Ecosim (EwE) model describing the overall structure and function of the ecosystem by including landings and discards of exploited stocks and estimations of the bycatch of non-target compartments. Second, a set of ecological indices and a trophic level (TL)-based model (EcoTroph, ET) were derived from the EwE model. ET was used to simulate the effects of increasing fishing pressure on the ecosystem and, more particularly, on top...

Analyse des captures accidentelles de mammifères marins dans les pêcheries françaises aux filets fixes
Provedor de dados: 5
Autores: Morizur, Yvon; Gaudou, Olivier; Demaneche, Sebastien.
During the years 2008 to 2013 several observations of catches were planned on board of set netters fishing in the bay of Biscay, in the English Channel, in the North sea and in the Mediterranean area (around Corsica). All the observations were done on nets without pingers and they were pooled to provide an average bycatch rate of marine mammals by fleet. Estimates of annual bycatch by using the fishing efforts of the year 2012 were provided by fleet. Harbour porpoise Phocoena phocoena was the most common bycatch in set nets. An average annual estimate of 600 harbour porpoises was obtained for the French fleet; other species recorded in set nets were mainly common dolphin Delphinus delphis, striped dolphin Stenella coeruleoalba and the two species of seals...

This document presents the results of a study on the impact of the french albacore tuna drift net fishery, mainly at the dolphins population level. Data collected during two embarked observers campains in 1992 and 1993 and the results of a sighting survey in 1993 give an estimation of the population size of common and striped dolphins (61 888 and 73 843) and mean values of ratio fishing of mortality (0.7 and 1.6%). A model was built in order to simulate the effect of the 5% upper limits of fishing mortality (1.5 and 3%). These values would leed to an annual rate of decrease of -1 %. It is unlikely that such values would jeopardize the survival and the presence of these species. Total incidental catches represent 15% of these total catch; albacore tuna...

Analyse des risques pour les mammifères marins liés à l'emploi des méthodes acoustiques en océanographie
Provedor de dados: 5
Autores: Lurton, Xavier; Antoine, Loic.
The use of acoustical systems in various human activities in the ocean (industry, defence, science) raises the issue of their impact upon marine mammals populations. Several serious accidents linked to the use of naval sonars led the military, industrial and scientific communities to investigate the potential dangers of their own activity.    This report aims at identifying the risks for the cetaceans linked to the use of acoustic and seismic systems currently used for oceanographic science. The analysis proposed here stays within the frame of bibliography synthesis and elementary modelling, and brings no new scientific elements on the topic. An overview of the status of cetacean populations is given first, with a summary of the possible acoustical...

Cetaceans in the Indian Ocean Sanctuary: A Review
Provedor de dados: 20
Autores: Parsons, E.C.M.; Jenner, K.C.S.; Baldwin, R.; Rudolph, P.; de Boer, M.N.; Eyre, E.L.; Simmonds, M.P.; Keith, S.G.; Rosenbaum, H.C.; Peddemors, V.M.; McCabe, K.A.; Burton, C.L.K.; Jenner, M.N.M.
This paper presents a synthesis of mainly published information relating to the cetaceans of the Indian Ocean Sanctuary (IOS). It highlights a number of new studies and other initiatives linked to the Sanctuary and reviews the current understanding of the biology of the Sanctuary’s cetaceans. Cetaceans in the IOS are exposed to a range of threats, including by-catch and the effects of climate change. Whilst no quantification can be made of these threats at this time, they may still be significant for the conservation of populations. The role of the IOS in stimulating research to further establish the status of cetacean populations is acknowledged.

Shifting baselines and the extinction of the Caribbean monk seal
Provedor de dados: 20
Autores: Baisre, J. A.
The recent extinction of the Caribbean monk seal Monachus tropicalis has been considered an example of a human-caused extinction in the marine environment, and this species was considered a driver of the changes that have occurred in the structure of Caribbean coral reef ecosystems since colonial times. I searched archaeological records, historical data, and geographic names (used as a proxy of the presence of seals) and evaluated the use and quality of these data to conclude that since prehistoric times the Caribbean monk seal was always rare and vulnerable to human predation. This finding supports the hypothesis that in AD 1500, the Caribbean monk seal persisted as a small fragmented population in which individuals were confined to small keys, banks, or...

African Penguins Spheniscus Demersus Along The Kwazulu-Natal Coast, 1981–1999
Provedor de dados: 20
Autores: Whittington, P.A.; Underhill, L.G.; Esmonde-White, D.A.; Wilkinson, C.P.
The African Penguin is rare east of Algoa Bay, Eastern Cape, South Africa. Ninety-nine penguins were found onshore along the coast of KwaZulu-Natal in 1981–1999, mostly in a state of starvation. Of these, 77% were between June and October during, and immediately after, the ‘sardine run’ of Sardine Sardinops sagax; 95% of birds that were aged were first-year birds; 96% were in the southern half of KwaZulu-Natal, south of Mtunzini (29°S) where the sardine run is strongest. The observations suggest that juvenile penguins from the nearest breeding colonies, in Algoa Bay, are drawn eastwards by the migrating Sardines; when these shoals dissipate, a lack of food leads to them coming ashore.

La presencia del reforzador primario después de cada comportamiento interrumpe la secuencia del espectáculo subacuático. En este espectáculo, delfines y entrenadores deben realizar varios comportamientos sincronizados bajo el agua durante 10 y 12 minutos. El encadenamiento (Skinner, 1938) fue la técnica que se eligió como solución a este problema. Se entrenaron dos delfines hembras Tursiops truncatus de aproximadamente dos años de edad cada una. Estos ejemplares no habían recibido entrenamiento con anterioridad. Se trabajó en una piscina de 480 metros cúbicos de agua, con una pared de acrílico de 12 X 4 X 0.22 metros. En seis meses se obtuvieron los 15 comportamientos básicos bajo estímulos controlados, con una frecuencia de cinco sesiones diarias de...

An Annotated Bibliography of Available Literature regarding cetacean Interactions with Tuna Pure Seine Fisheries Outside of the eastern Tropical Pacific
Provedor de dados: 20
Autores: Edwards, E.F.; Donahue, M.
A review of currently available literature conceming interactions between tuna purse-seines and dolphins outside the eastern tropical Pacific Ocean (ETP) does not indicate any large, sustained, or widespread practice of setting purse seine nets around cetaceans for the purpose of catching tuna in any oceanic area other than in the ETP. While a number of individual reports exist of purse-seine sets made on cetaceans during the process of fishing for tuna in areas other than the ETP, there is no quantitative or even anecdotal indication that large-scale sustained directed fishing on cetaceans during tuna purse-seining occurs anywhere other than in the ETP. However, this lack of information should not be mistaken for conclusive evidence that such large-scale...

Two West Indian manatees (Trichechus manatus spp.) were reported with severe emaciation. One animal was a Florida manatee from the Everglades; the other was an Antillean manatee from Cuba. On necropsy, both animals had nephrolithiasis, pyelonephritis, and moderate to severe renomegaly. Histopathology revealed multifocal to diffuse pyelonephritis, interstitial nephritis, and nephrocalcinosis. The stones were analyzed and consisted primarily of calcium carbonate. Serum chemistry values for the Florida animal revealed no renal abnormalities. The mechanism of calculus formation remains unclear in manatees. In horses, another hindgut fermenter, the most common urolith is also calcium carbonate. Urinalyses performed on manatees are very similar to those of...

There is not published information on a comparative analysis about interchange of individual humpback whales between coastal areas of aggregation of the species along southern Chilean coast. Here we present a comparison of individually photo-identified humpback whales obtained off northwestern Chiloé Island, in Patagonian and Fuegian fjords and in the Strait of Magellan near Carlos III Island , to discover movements and interchange of individuals. Comparison of photographs resulted in conclusive matches of four individuals within the four study locations: two whales from Canal Wide (49°55’S, 74°30’W), one whale from Canal Cockburn (54°18’S, 72°15’W) and a mother-calf pair off northwestern Chiloé Island matched whales found near Carlos III.

La papilomatosis es una entidad tumoral generalmente benigna que ataca la piel y mucosas de diferentes zonas del cuerpo. Esta enfermedad puede limitar la reproducción en los cetáceos y una de sus causas puede ser la infección por papilomavirus. La observación de pequeñas verrugas en la piel o mucosas de estos animales hace inferir la presencia de lesiones papilomatosas.

Cetacean Species Occurring in the Mediterranean and Black Seas
Provedor de dados: 20
Autores: Notarbartolo di Sciara, G.
Twenty one species of cetaceans occur in various degrees of abundance in the Mediterranean Sea and in the Black Sea. This list corresponds to Annex 1 of the Agreement, with the addition of three species known to have occurred in the Mediterranean in subsequent times. The list also roughly corresponds to the species occurring in the Contiguous Atlantic Area, however we must caution that a considerable number of other species, commonly present throughout the Atlantic Ocean, may occur there. Furthermore, we note that the number of species which are known to occur in the Agreement area is likely to grow with time, as the attention of scientists and laypersons towards cetaceans increases, and considering that species hitherto unreported from the region may...

Marine mammal strandings: technical control on site
Provedor de dados: 27
Autores: Tavernier, J.
Strandings of marine mammals are always an unusual occurrence. Whether the animals are living or dead, these events require the input of many services and people. Techniques can be implemented to protect the animals, stabilise them, transport them, or -when they are dead- dispose of them properly. Technical coordination on the beach is therefore an important factor for success. The paper examines the various possible types of strandings and the different methods of intervention.

Patterns of organic contaminants in marine mammals with reference to sperm whale strandings
Provedor de dados: 27
Autores: Wells, D.E.; McKenzie, C.; Ross, H.M.
Discriminant analysis has been applied to organochlorine contaminant data from a small number (&lt;i&gt;ca&lt;/i&gt; 3-25) of 12 different marine mammal species to discriminate between the species on the basis of the chlorobiphenyls (CB) patterns in blubber and account for the effects of age, sex, condition and location of the mammals. The raw data are normalised to a single congener, CB 153, to reduce the effects of life history and sex, after which the discriminant factors are plotted to display the differences between species in relation to the intake and the metabolism of chlorobiphenyls. An understanding of these differences gives a better knowledge of the relative sensibility of these species. The sperm whales were found to have the least ability to...

ABSTRACT Marine mammal strandings provide valuable insights into local biodiversity. Strandings can be caused by both natural and anthropogenic factors. In the state of Santa Catarina, Southern Brazil, organized marine mammal collections started in the 1980s through opportunistic and non-systematic collection efforts, representing a record of over 30 years of marine biodiversity. This study aimed to perform a preliminary review of 32 years of stranding records within this region. The secondary aim was to elucidate the stranding dynamics of the three most commonly recorded species. A total of 460 records were obtained, representing 17 species of odontocetes. The species registered most frequently were the franciscana, Pontoporia blainvillei (Gervais &amp;...

Autores: Batista,Renata Lúcia Guedes; Schiavetti,Alexandre; Santos,Urânia Amaral dos; Reis,Maria do Socorro Santos dos.
Stranded cetaceans have scientific value and may confirm the occurrence of some species or indicate their geographical distribution in an area. The collection of biological material can also contribute to improve the knowledge of the species or populations inhabiting certain areas. This study aimed to record live or dead cetaceans found ashore along the coast of Ilhéus, Bahia State, northeastern Brazil. Data were collected through a campaign called "SOS strandings, whales, porpoises and dolphins." Between 1997 and 1999 three hundred posters and five hundred folders were distributed to beach huts, shops, fishing associations and settlements, the city's municipal government, the Brazilian Environmental Agency (IBAMA) and fire stations. During this campaign,...

Gastric lesions associated with the presence of Anisakis spp. Dujardin, 1845 (Nematoda: Anisakidae) in Cetaceans stranded on the coast of Ceara, Brazil
Provedor de dados: 49
Autores: Motta,Monica Regina Alves; Pinheiro,Diana Célia Sousa Nunes; Carvalho,Vitor Luz; Viana,Daniel de Araújo; Vicente,Ana Carolina Paulo; Iñiguez,Alena Mayo.
The gastric compartments of ten cetaceans stranded on the coast of Ceará State, Northeast Brazil were analyzed in this study. Gastric Anisakis spp. was diagnosed in all individuals involved in this study. Parasites and tissue samples were collected during necropsy. The presence of Anisakis parasites showed similar distribution across the three gastric compartments and the majority was free within the gastric lumen. Macroscopically, the lesions were predominantly characterized by the presence of ulcers (60%, 6/10) within the gastric mucosa, occasionally associated with edema and hemorrhage (30%, 3/10). Eight cetaceans (8/10 - 80%) presented gastric microscopic alterations and in 75% (6/8) of these animals, chronic lymphoplasmocytic gastritis was observed...

Provedor de dados: 58
Autores: Pereira,Christiane S.; Amorim,Simone D.; Santos,André Felipe das M.; Siciliano,Salvatore; Moreno,Ignacio B.; Ott,Paulo Henrique; Rodrigues,Dalia dos Prazeres.
The aquatic environment is the habitat of many microorganisms, including Plesiomonasshigelloides and Aeromonas species which are pathogenic to human and animals. In the present investigation, we evaluated the occurrence of these pathogens from marine mammals beached or accidentally captured by fishing net in southeastern (RJ) and southern (RS) coastal Brazilian regions. A total of 198 swabs from 27 specimens of marine mammals, including 11 different species, were collected by DEENSP and GEMARS-CECLIMAR/UFRGS Institutes and sent to LRNCEB/IOC/FIOCRUZ. The samples were enriched in Alkaline Peptone Water (APW) added with 1% of sodium chloride (NaCl), APW plus 3% NaCl and incubated at 37ºC for 18-24 hours. Following, samples were streaked onto...
