A hierarchical Bayesian model for embedding larval drift and habitat models in integrated life cycles for exploited fish ArchiMer
Rochette, Sebastien; Le Pape, Olivier; Vigneau, Joel; Rivot, Etienne.
This paper proposes a hierarchical Bayesian framework for modeling the life cycle of marine exploited fish with a spatial perspective. The application was developed for a nursery-dependent fish species, the common sole (Solea solea), on the Eastern Channel population (Western Europe). The approach combined processes of different natures and various sources of observations within an integrated framework for life-cycle modeling: (1) outputs of an individual-based model for larval drift and survival that provided yearly estimates of the dispersion and mortality of eggs and larvae, from spawning grounds to settlement in several coastal nurseries; (2) a habitat suitability model, based on juvenile trawl surveys coupled with a geographic information system, to...

Age and growth of Cetengraulis edentulus (Clupeiformes: Engraulidae) in a subtropical bight of Southern Coast Brazil Rev. Bras. Zool.
Souza-Conceição,José Maria; Schwingel,Paulo Ricardo.
Age and growth of Cetengraulis edentulus (Cuvier, 1828) in the Saco dos Limões bight (Southern Brazil) were studied. Sampling was carried out from August 2001 to July 2003. The study of age and growth was based on the interpretation of the periodicity of ring formation in the otoliths sagittae of 491 individuals, temporal variation of otolith edge, relative marginal increments (RMI), age-length key, and von Bertalanffy curve. Cetengraulis edentulus otoliths were adequate for the interpretation of age with 86% of legibility, in which a translucent zone and its adjacent opaque zone were deposited each year. The translucent zone is formed during the cold period and the opaque zone in the warm period. Fish aged 0 (<12 months) - 4.0 year old were found and...

Hauser,Marília; Doria,Carolina R. C.; Melo,Larissa R. C.; Santos,Ariel R.; Ayala,Daiana M.; Nogueira,Lorena D.; Amadio,Sidinéia; Fabré,Nídia; Torrente-Vilara,Gislene; García-Vásquez,Áurea; Renno,Jean-François; Carvajal-Vallejos,Fernando M.; Alonso,Juan C.; Nuñez,Jésus; Duponchelle,Fabrice.
ABSTRACT The goliath catfish Brachyplatystoma rousseauxii has crucial economical and ecological functions in the Amazon basin. Although its life history characteristics have been studied in the Amazon, there is little information in the Madeira River basin, which holds genetically distinct populations and where dams were recently built. Using fish collected in Bolivia, Brazil and Peru, this study provides a validation of growth rings deposition and details the growth patterns of B. rousseauxii in the Madeira before the dams’ construction. Age structure and growth parameters were determined from 497 otolith readings. The species exhibits two growth rings per year and sampled fish were between 0 and 16 years old. In the Brazilian portion of the basin, mainly...

Souza,Thamyrys B.; Maia,Artur C.D.; Albuquerque,Cleide M.R.; Iannuzzi,Luciana.
Adults of Cyclocephala distincta are flower visitors of Neotropical palms (Arecaceae) and commonly found in the Atlantic Forest of Pernambuco, Brazil. Males and females were collected in the wild and subjected to captive rearing and breeding. The egg hatching rate, the life cycle, longevity of immatures and adults, and oviposition parameters in captivity were analyzed. The average duration of the life cycle of C. distinctawas 108.2 days (n = 45). The egg stage lasted on average 10.9 days, and the egg-hatching rate was 73.9%. The immature stage lasted on average 93.4 days. The larvae stage exhibited negative phototaxis, and the size of their head capsules increased at a constant rate of 1.6 between instars, following Dyar's rule. The average duration of the...

Biology of Corecoris dentiventris Berg, 1884 (Hemiptera, Coreidae) in tobacco culture (Nicotiana tabacum) BJB
CALDAS,B.-H. C.; REDAELLI,L. R.; DIEFENBACH,L. M. G..
Corecoris dentiventris Berg, 1884 (HEM., Coreidae) represents a pest in the tobacco culture in Southern Brazil. Nymphs and adults cause the wilting and twisting of the tobacco leaves due to their sucking habit. There are very few works about this species and these are restricted to concise description of the adult morphology, records of host plants and enumeration of injuries. The present investigation aims to study the life cycle of this bug. The experiment was carried out in a tobacco culture (Virginia type, var. K 326) implanted in the experimental area of the Departamento de Fitossanidade of the Universidade Federal do Rio Grande do Sul, in Porto Alegre, RS. The life cycle was studied in field conditions, in nylon cages, from egg clusters oviposited by...

Biology of nymphs of Rhodnius robustus Larrousse, 1927 (Hemiptera, Rreduviidae), fed on pigeon or on swiss mouse blood in laboratory conditions BJB
BRAGA,M. V.; PRATA,K. C.; BRAZIL,R. P..
The duration of the life cycle of Rhodnius robustus Larrousse, 1927 as well as the mortality rate of each nymphal instar were studied comparing groups fed on pigeon or on mouse blood weekly or fortnightly. This species showed a better development and lower mortality rate when fed on swiss mouse. The intervals between feedings apparently did not have influence on the shortening of the cycle. We suggest that laboratory colonies and experiments with R. robustus are better maintained when these triatomines are fed on swiss mouse.

Black scabbardfish, Aphanopus carbo, in the northeast Atlantic: distribution and hypothetical migratory cycle ArchiMer
Farias, Ines; Morales-nin, Beatriz; Lorance, Pascal; Figueiredo, Ivone.
The biology, ecology, and dynamics of the deep-sea teleost black scabbardfish in the northeast Atlantic are reviewed. The black scabbardfish is a commercial bathypelagic species found in the NE Atlantic mostly from Iceland to the Canary Islands and Western Sahara, at depths from 800 to 1300 m. The spatial structure of its population is still uncertain, although the existence of one single stock that migrates around the NE Atlantic driven by feeding and reproduction is the most likely hypothesis consistent with available data. This review is based on data from commercial fisheries off the Faroe Islands, Hatton Bank, the west of the British Isles, and Portugal (mainland, Azores, and Madeira) and from Icelandic and Scottish scientific surveys collected...

Brooding in a temperate zone land snail: seasonal and regional patterns Naturalis
Sulikowska-Drozd, A.; Maltz, T.K.; Kappes, H..
The goal of this study is to assess if the reproductive strategy of a brooding land snail shifts along a climatic gradient. We focused on the following traits: timing and length of the reproductive season, brood size, ontogenetic dynamics of embryos, and reproductive mode (viviparity versus egg-laying). We dissected the central European door snail Alinda biplicata, collected monthly from eight populations covering the oceaniccontinental climatic gradient within the species’ distribution range. Forty percent of the 1706 dissected individuals were brooding. The species displayed a spring-summer reproductive activity pattern: intrauterine brooding was recorded between March and September; first embryos of a developmental stage that equals that of live-born...

Características ecológicas del pulpito Octopus Tehuelchus en tres ambientes del golfo San Matías OceanDocs
Storero, L.P..
Coastal marine ecosystems are highly variable and the inherent biotic and abiotic factors of these environments can influence the bio-ecological characteristics of the living cephalopods. The presence of the small octopus “pulpito” Octopus tehuelchus in the coastal environments of San Matías Gulf has been exploited by artisanal fishermen for more than 60 years. The aim of this study is to evaluate the variations in the life cycle of the pulpito, and the factors that could account for these variations in three different coastal environments of San Matías Gulf, with differences in the physical, ecological and fisheries characteristics. This study was developed in San Antonio bay, El Fuerte and Islote Lobos. Monthly samplings (October 2005-2007) in the...
