A framework for selecting a suite of indicators for fisheries management ArchiMer
Rice, Jake; Rochet, Marie-joelle.
We develop a framework for the objective selection of a suite of indicators for use in fisheries management. The framework encompasses eight steps, and provides guidance on pitfalls to be avoided at each step. Step I identifies user groups and their needs, featuring the setting of operational objectives, and Step 2 identifies a corresponding list of candidate indicators. Step 3 assigns weights to nine screening criteria for the candidate indicators: concreteness, theoretical basis, public awareness, cost, measurement, historic data, sensitivity, responsiveness, and specificity. Step 4 scores the indicators against the criteria, and Step 5 summarizes the results. Steps 3-5 offer technical aspects on which guidance is provided, including scoring standards...

A new Cretaceous terrestrial ecosystem from Gondwana with the description of a new sauropod dinosaur Anais da ABC (AABC)
Calvo,Jorge O.; Porfiri,Juan D.; González-Riga,Bernardo J.; Kellner,Alexander W.A..
A unique site at the northern area of Patagonia (Neuquén, Argentina) reveals a terrestrial ecosystem preserved in a detail never reported before in a Late Cretaceous deposit. An extraordinary diversity and abundance of fossils was found concentrated in a 0.5 m horizon in the same quarry, including a new titanosaur sauropod, Futalognkosaurus dukei n.gen., n.sp, which is the most complete giant dinosaur known so far. Several plant leaves, showing a predominance of angiosperms over gymnosperms that likely constituted the diet of F. dukei were found too. Other dinosaurs (sauropods, theropods, ornithopods), crocodylomorphs, pterosaurs, and fishes were also discovered, allowing a partial reconstruction of this Gondwanan continental ecosystem.

Análise do meio físico para avaliação das limitações ambientais. Repositório Alice
RESENDE, M.; SANTANA, D. P.; BAHIA FILHO, A. F. C.; SANS, L. M. A..
Embora semelhante do ponto de vista macroclimatico, ecossistemas contiguos podem apresentar profundas diferencas no aspectos microclimatico, bem como na disponibilidade de agua e envolvendo componentes de clima, de solo e vegetacao, faz com que as analises para estratificacao ambiental reunam um numero relativamente grande de informações que nem sempre estao sistematizadas. Por outro lado, o caracter interativo das relacoes existentes torna o processo complexo, demandando uma abordagem estratificacao de ambientes em termos de radiacao, disponibilidade de agua e nutrientes e de alguns fatores coadjuvantes. Em virtude de a grande maioria dos criterios utilizados para estratificacao de ambientes serem de uso corrente nos estudos de mapeamentos de solos,...

Analyse des résultats d'une ferme d'élevage de crevettes sur 20 années : SODACAL 1984-2004. "Elasticité" de la capacité de production d'un écosystème bassin crevetticole ArchiMer
Della Patrona, Luc.
SODACAL prawn farm which was set up as a pilot farm for the development of a prawn industry in New Caledonia, saw its production exponentially rise from 1984 to 1992 (to 400 t/year, then experienced a sharp drop in 1993 (250 t/year) which carried on until 1997, and finally rose back to a stabilizing level around 400 t/year until 1999. The study analyses the difficulties observed before and during the drop of production. Among them, mortality outbreaks, other biological perturbations (benthic mat clearing and crab and fish mortality) and focus on the noxious state of the bottom (reduced and smelling sulfide hydrogen). It particularly shows that Syndrome 93 outbreaks could be observed on this farm from 1990. The analysis highlights the particular climatic...

Anthropogenic impacts on the sediment flux in two alpine watersheds of the Lesser Himalayas Eprints@IARI
Singh, Omvir; Singh, Pratap; Sarangi, Arjamadutta; Sharma, M C; Kumar, Sanjeev.
Water erosion caused by accelerated anthropogenic activities has been perceived as the major source of sediment flow in Himalayan catchments. Keeping this in view, the sediment flux data measured at the outlet of the Sainj and the Tirthan watersheds in the Lesser Himalayan region was analysed. Rainfall behaviour coupled with existing forest cover, snow bound and glaciated areas with rocky outcrops in the Sainj watershed could result in more sediment yields as compared to the Tirthan. It was observed that the sediment flux from the Sainj watershed was 1.5 times more than the Tirthan watershed. Also, the sediment transport from both watersheds showed an increasing trend in the monthly, seasonal and annual flux during the study period (1981–2004). This...

Blue fishing and aquaculture: threats, obstacles and opportunities ArchiMer
Goulletquer, Philippe.
On estime à l'heure actuelle que la consommation de poisson par habitant devrait doubler d'ici à 2030, comme elle l'a fait entre 1973 et 2003. Que devons-nous faire pour mieux préserver (voire accroître) les réserves de poisson, qui sont en diminution constante ? Qu'en est-il de l'aquaculture ? Peut-elle répondre à cette demande croissante, et si oui quel en sera l'impact environnemental ? Comment les pays pauvres peuvent-ils en particulier exiger des sociétés qui la pratiquent de prendre en charge les frais supplémentaires liés à une production d'aquaculture durable ?

Developmental Disorders as Pathological Resilience Domains Ecology and Society
Wallace, Rodrick; ; wallace@pi.cpmc.columbia.edu.
Ecosystem resilience theory permits novel exploration of developmental psychiatric and chronic physical disorders. Structured psychosocial stress, and similar noxious exposures, can write distorted images of themselves onto child growth, and, if sufficiently powerful, adult development as well, initiating a punctuated life course trajectory to characteristic forms of comorbid mind/body dysfunction. For an individual, within the linked network of broadly cognitive psysiological and mental subsystems, this occurs in a manner almost exactly similar to resilience domain shifts affecting a stressed ecosystem, suggesting that reversal or palliation may often be exceedingly difficult. Thus resilience theory may contribute significant new perspectives to the...

Ecossistema de pastagem cultivada na Amazônia brasileira. Infoteca-e
FALESI, I. C..
A pesquisa foi realizada em áreas com pastos de idades diferentes, desde meses de idade (formação) ate 11 anos, tomando-se a área com floresta natural como elemento de comparação (testemunha). Foram coletadas amostras de solos de 0-20 cm em cada uma dessas áreas, alem da coleta de perfis pedagógicos ate a uma profundidade de 1,50 m. Apos a obtenção das analises no laboratório, constatou-se que vários nutrientes e índices ou valores, sofreram acréscimos quando o solo foi cultivado com pastagem, melhorando portanto, as suas propriedades químicas. Os elementos que mais se evidenciaram, foram: cálcio, magnésio, fosforo, alumínio, e os índices de pH, V (saturação de bases), S (soma de bases) e saturação de alumínio. Os quadros de analises e gráficos constantes...

A caatinga e a vegetacao tipica da regiao semi-arida do Nordeste do Brasil. O clima e caracterizado por uma baixa precipitacao anual e uma distribuicao irregular nas diversas areas da regiao. Os tipos de solos predominantes sao o litolico e o bruno nao-calcico. A vegetacao natural consiste de associacoes de especies, sendo mais comuns as plantas lenhosas de 3 a 5 metros de altura. Os animais domesticos desempenham um importante papel nos sistemas de producao das fazenda, os quais sao geralmente baseados em pastagens. Os rebanhos pastejam de forma extensiva na vegetacao nativa, onde a superlotacao e a regra e os niveis de producao sao os mais baixos do pais. Contudo, este sistema de producao provoca uma adaptacao as condicoes ambientais adversas, permitin...

Ecosystem approach to fisheries: a brief overview and some considerations for its application in ICCAT ArchiMer
Fromentin, Jean-marc; Fonteneau, Alain; Restrepo, Victor.
During the last SCRS plenary meeting, the sub-committee on environment suggested to present a document on the ‘Ecosystem Approach to Fisheries’ (EAF). This document firstly recalls the general scientific and institutional background of EAF, then we propose a synoptic view of EAF, including four main domains: governance, exploitation, resources and impacts on ecosystems. The way that EAF is tackled within the various tuna commissions is then summarised. Finally, we rapidly examine the way the SCRS could cope with EAF issues and we suggest to merge the sub-committee on environment with this on by-catch into a single subcommittee on ecosystem.

Ecosystem Services and Food Security: Economic Perspectives on Environmental Sustainability AgEcon
Richardson, Robert B..
Food security in developing countries depends in part on the sustainable use of natural resources. Food security is usually examined through three dimensions, namely the availability, access, and utilization of food. Ecosystems directly and indirectly support each of these dimensions through the provision of critical ecosystem services that facilitate agricultural production, create income- generating opportunities, and provide energy for cooking. However, in some cases, household uses of natural resources undermine particular elements of food security, hindering national poverty reduction strategies and threatening the sustainability of critical ecosystem functions. I examine the role of ecosystem services in rural food security through the lens of its...

Emergence of biodiversity research and main progress from Ifremer ArchiMer
Desbruyeres, Daniel; Goulletquer, Philippe.
Research needs and interests on biodiversity have drastically increased since the Rio Conference (1992). The main conclusions from the Millennium Ecosystem Assessment (MEA, 2001) carried out by the UN and the demonstration of the critical role of biodiversity in maintaining ecosystems services have strengthened research interests on biodiversity. Moreover, the systemic approach generalization, complex system modeling, confluence of thematic prompting new scientific concepts, and multi-scalar – multifunctional approach have induced significant changes to the scientific context. A review of major advances on biodiversity monitoring and research resulting from Ifremer programs will be presented considering deep sea as well as coastal ecosystems and associated...

Management actions to protect endangered species and conserve ecosystem function may not always be in precise alignment. Efforts to recover the California Ridgway’s Rail (Rallus obsoletus obsoletus; hereafter, California rail), a federally and state-listed species, and restoration of tidal marsh ecosystems in the San Francisco Bay estuary provide a prime example of habitat restoration that has conflicted with species conservation. On the brink of extinction from habitat loss and degradation, and non-native predators in the 1990s, California rail populations responded positively to introduction of a non-native plant, Atlantic cordgrass (Spartina alterniflora). California rail populations were in substantial decline when the non-native Spartina...
