AÇÃO EXTENSIONISTA DA EMPAER FRENTE À NOVA PNATER: UMA ANÁLISE A PARTIR DO ASSENTAMENTO GUAPIRAMA, CAMPO NOVO DO PARECIS - MT AgEcon
Laforga, Gilmar; Vieira, Andreia De Oliveira.
O modelo de agricultura ainda praticado continua a causar impactos negativos como a perda de solo, erosão genética, contaminação do solo e da água entre muitos outros efeitos. Considerando-se esse cenário e assim buscar minimizar estes processos, foi criada a Política Nacional de Assistência Técnica e Extensão Rural – PNATER, que orienta uma extensão rural baseada nos princípios epistemológico da agroecologia. Entre as mudanças, está à exigência de um novo perfil de extensionista, uso de metodologias participativas, minimização de utilização de recursos externos à propriedade, e a produção de vegetais e animais com a mínima degradação dos recursos naturais. O presente trabalho tem por objetivo analisar se essas mudanças estão sendo efetivamente empregadas...

Collective Retaliation and the WTO Dispute Settlement System AgEcon
Korotana, M.S..
Article 22 of the Dispute Settlement Understanding (DSU) of the WTO offers, as last resort countermeasures, withdrawal of the concessions the state parties had agreed to in their schedules of commitments. The problem is that such a withdrawal of concessions would have very little impact on the economy and consequently on the behaviour of the respondent state if that party happened to be a developed state vis-à-vis a small, developing country. To deal with this situation a remedy of “collective countermeasures”, contained in Article 54 of the Draft Articles on State Responsibility of the International Law Commission (ILC), has been proposed; it has been argued that this remedy should apply, as a general principle of public international law, as a last...

Combined effects of temperature-salinity on larval survival of the Eastern oyster Crassostrea virginica in the Maryland portion of the Chesapeak Bay (USA) ArchiMer
Goulletquer, Philippe; Heral, Maurice; Prou, Jean.
Oyster landings in the Maryland portion of the Chesapeake Bay have declined by more than 50fold since the early part of the century, despite intensive management efforts. The annual shell repletion program is the most critical programmatic element to effect recovery of the ailing Eastern oyster Crassotrea virginica stock and fishery. The overall efficacy of shell repletion management depends primarily on the success of spat settlement on the planted shell, and furthermore on their survival rate. The Operations Research techniques and mathematical programming developed by Rothschild et al. (1991) attempt to maximize spat recruitment to the oyster stock subject to a series of operational constraints. Allocation and timing of shell deployment are the most...

Crypsis in early benthic phases of Brachyuran Decapod Crustaceans in central Chile RChHN
PALMA,ÁLVARO T.; ORREGO,CAEL; ARRIAGADA,MAURICIO.
Although common and in some cases of commercial value, little is known about the mechanisms and processes that affect the distribution and abundance of many species of decapod crustaceans, particularly in Chile. All of these species have planktonic larvae that must settle and recruit before becoming part of the adult segments of their populations. For several of these species we have detected the presence of a variety of color morphs in newly settled individuals. The existence of these morphs in Chilean species is comparable with those observed in other latitudes (e.g., coast of the Gulf of Maine). On the other hand, it is characteristic that the occurrence of these patterns only appears during the early juvenile stages and that after reaching a certain...

Duration of the pre-settlement period of the mangrove crab Ucides cordatus (Decapoda: Ocypodidae) under laboratory conditions BABT
Ventura,Robson; Silva,Ubiratã de Assis Teixeira da; Perbiche-Neves,Gilmar; Ostrensky,Antonio; Boeger,Walter Antonio Pereira; Pie,Marcio Roberto.
The goal of the present study was to determine the most appropriate time to release the immatures of Ucides cordatus (Linnaeus) produced in the laboratory into the natural environments. Specifically, the time when the megalopae sought the mangrove sediment to excavate the burrows was determined, as well as the time necessary for their metamorphosis into the first juvenile stage. Results indicated that the megalopae of U. cordatus reared in the laboratory took three to ten days (median = 6) after their molt to excavated burrows in the sediment. The average time for the megalopae to molt into juveniles was 12.6 days (SD = 2.3).

Effect of microhabitat distribution and substrate roughness on barnacle Tetraclita stalactifera (Lamarck, 1818) settlement BABT
Skinner,Luís Felipe; Coutinho,Ricardo.
Studies were carried out on microhabitat distribution and substrate roughness on barnacle settlement at Cabo Frio region, Rio de Janeiro, Brazil. Ten commercial blocks of granite rock (100 cm²) were attached to rocky coast at 0.6 tide level (5 smooth blocks and 5 rough with 20 holes). Experiment was conduced for five weeks, with repetitions each week. Settlement was higher on rough (398 individuals) than on smooth blocks (38 individuals) on the same week. There was no significant difference between settlement in the centre of the block and at the edge. Significant differences observed among weeks were affected by the variability of cyprid larvae density. This result showed that roughness was an important variable to be considered on barnacle settlement.

First field record of mangrove crab Ucides cordatus (Crustacea: Decapoda: Ucididae) recruits co-inhabiting burrows of conspecific crabs Rev. Bras. Zool.
Schmidt,Anders Jensen; Diele,Karen.
Recruits of the mangrove crab Ucides cordatus (Linnaeus, 1763), rarely encountered in the field were found co-inhabiting burrows of larger male and female conspecifics in the mangrove forest. They were located in the sediment of the inner walls and burrow plugs. Average carapace width (CW) of the hosting and co-inhabiting crabs was 3.8 ± 0.20 and 0.9 ± 0.03, respectively. As shown by the size-frequency distribution, while most recruits leave the conspecific burrows after reaching 1.0 cm CW, some stay until they reach a size of 2.5 cm CW. The results of this study contribute to a better understanding of recruitment patterns in this ecologically and economically important mangrove crab species. Follow-up studies are however needed to fully determine the role...

Food access and consumption in a rural settlement in Castanhal, PA, Brazil Ciênc. Tecnol. Aliment.
PORTAL,Riziane Duarte; LIMA,Suely Cristina Gomes de; JOELE,Maria Regina S. Peixoto.
Abstract The study aimed to assess the food accessibility and consumption among families in the Cupiúba rural settlement, in the city of Castanhal, Pará, Brazil. It was found that the access to food is worrying and indicated that most families are in food insecurity conditions. Moreover, income and food safety level were associated. The consumption of the settler families comprises mainly high-energy, low-nutrient content foods, characterized by the low intake of fruits and vegetables and the introduction of processed foods with high energy density and sugar-added beverages, although the traditional dietary habits (rice and beans) are still present. This configures a diet at risk for important nutritional deficits, obesity, and many non-communicable...

Influence of natural settlement cues on the metamorphosis of fiddler crab megalopae, Uca vocator (Decapoda: Ocypodidae) Anais da ABC (AABC)
Simith,Darlan J.B.; Diele,Karen; Abrunhosa,Fernando A..
Megalopae of many decapod crab species accelerate their development time to metamorphosis (TTM) when exposed to natural physical and/or chemical cues characteristic of the parental habitat. In the present study, the influence of natural settlement cues on the moulting rates and development TTM in megalopae of the fiddler crab Uca vocator was investigated. The effects of mud from different habitats (including well-preserved and degraded-polluted mangrove habitats) and conspecific adult 'odours' (seawater conditioned with crabs) on the induction of metamorphosis were compared with filtered pure seawater (control). 95 to 100% of the megalopae successfully metamorphosed to first juvenile crab stage in all treatments, including the control. However, the...

Lethal and sub-lethal effects of Deepwater Horizon slick oil and dispersant on oyster (Crassostrea virginica) larvae ArchiMer
Vignier, J.; Soudant, P.; Chu, F. L. E.; Morris, J. M.; Carney, M. W.; Lay, C. R.; Krasnec, M. O.; Robert, Rene; Volety, A. K..
In April 2010, crude oil was spilled from the Deepwater Horizon (DWH) oil platform for 87 days, coincident with the spawning season and recruitment of the oyster, Crassostrea virginica, in the Gulf of Mexico. Impacts of acute exposures to surface-collected DWH oil (HEWAF), dispersed oil (CEWAF) and dispersant alone (Corexit 9500A®) on planktonic larval stages of C. virginica (veliger, umbo and pediveliger) were tested in the laboratory. Exposures to HEWAF, CEWAF and dispersant were toxic to larvae impairing growth, settlement success and ultimately survival. Larval growth and settlement were reduced at concentrations of tPAH50 ranging from 1.7 to 106 μg L−1 for HEWAF and 1.1–35 μg L−1 for CEWAF, concentrations well within the range of water sampled during...

Relationship between pre- and post-metamorphic growth in the Pacific oyster Crassostrea gigas (Thunberg) ArchiMer
Collet, Bertrand; Boudry, Pierre; Thebault, Anne; Heurtebise, Serge; Morand, Berenice; Gerard, Andre.
Twenty male and 20 female parental oysters, originating from four sites located along the French Atlantic coast, were crossed together. The 400 crosses were performed separately and then pooled to give a batch of larvae with a large genetic base. Successive sieving after 17 days at 23°C enabled the separation of the largest larvae from the batch. These larvae (i.e., sieving groups) were left to metamorphose and fix onto flat PVC collectors changed daily. Four groups of larvae representing distinctly different growth rates were successively separated during the attachment and metamorphosis of the whole population. This lasted 12 days, from the 17th day to the 29th after fertilisation. A part of each sieving group was settled separately as replicates on...

Rising water temperatures, reproduction and recruitment of an invasive oyster, Crassostrea gigas, on the French Atlantic coast ArchiMer
Dutertre, Mickael; Beninger, Peter G.; Barille, Laurent; Papin, Mathias; Haure, Joel.
The recent appearance and invasion of feral oysters (Crassostrea gigas) along the northern European Atlantic coast, underscores the necessity to investigate the relationship between environmental variables, reproductive physiology, larval development and recruitment. We studied these relationships at both high (HT) and intermediate (IT) - turbidity sites, through historical data on water temperatures, multi-parameter environmental probes, histological analyses, and field collections of planktonic larvae and settled post-larvae in 2005 and 2006. A progressive warming trend was observed, especially since 1995, when oyster proliferation first became severe. Threshold temperatures for oocyte growth, larval development and settlement were achieved in both 2005...
