Biometric and statistical investigations on the cnidoma of the genus Hydra (Cnidaria, Hydrozoa)
Provedor de dados: 76
Autores: Deserti,Maria I.; Zamponi,Mauricio O.
This paper deals about the nematocysts like a source of biometric information for comparison between the species Hydra vulgaris Pallas, 1766, Hydra vulgaris pedunculata Deserti et al., 2011 and Hydra pseudoligactis (Hyman, 1931). This biometric tool lets us carry out statistical comparisons and adding these results to the identification of specimens from different classificatory groups. In this particular study, we obtained significant differences between species, individuals of each species and nematocysts type when compared the biometry of its nematocysts. Another result was the variation in of particular nematocysts, like atrichous isorhiza and holotrichous isorhiza for the species H. vulgaris in relation to the column size.

Ictiômetro para biometria de surubins (pintado e cachara).
Provedor de dados: 14
Autores: ROTTA, M. A.
Atualmente o Brasil é considerado como o país de maior potencial para a aquicultura no mundo. Contribuem para isso o clima quente o ano todo na maior parte do país, os abundantes recursos hídricos, as grandes safras de grãos e a grande diversidade de espécies com potencial para cultivo, dentre os quais se destacam o pintado (Pseudoplatystoma corruscans) e o cachara (Pseudoplatystoma fasciatum), pertencentes a ordem Siluriformes e amplamente conhecidos como surubins. Com ocorrência no Pantanal e em outras bacias hidrográficas do território brasileiro, os surubins são os peixes de água doce de maior valor comercial, pois são bastante apreciados como espécies para mesa e pesca esportiva e reúnem atributos favoráveis para a criação de forma industrial:...

Estimativa do percentual de casca e do fator de forma em povoamentos jovens de teca(Tectona grandis L. f.).
Provedor de dados: 14
Autores: FIGUEIREDO, E. O.; SCOLFORO, J. R. S.; OLIVEIRA, A. D. de.
Um dos principais objetivos nos diagnósticos florestais é a obtenção de estimativas de volume total e comercial de madeira. Para isso existem metodologias que propiciam diferentes detalhamentos destas informações, como as funções de afilamentos e as equações de volume, dentre outras. Porém, em levantamentos rápidos, o fator de forma e as estimativas de percentual de casca podem ser empregados com segurança. O percentual de casca é um dos aspectos mais importantes no processo de avaliação de povoamentos florestais implantados, visto que, em algumas espécies florestais e em função da idade, o volume de casca representa um significativo percentual do volume total. Para teca, o comércio de toras é feito com base no diâmetro da extremidade mais fina da tora sem...

Identification des flux de civelles (Anguilla anguilla) à partir des relations d’allométrie en fonction des conditions hydrodynamiques de l’estuaire de l’Adour
Provedor de dados: 5
Autores: De Casamajor, Marie-noelle; Prouzet, Patrick; Lazure, Pascal.
Biological data on glass eels (Anguilla anguilla) were collected during two successive sampling periods from November to March (1996-1997 and 1997-1998) on the Adour estuary. As for other estuaries, decrease in length (mean of 73.5 to 67.4 mm) and weight (mean of 3.5 to 2.6 dg) of glass eels were observed. Weight and length characteristics were used to identify groups of glass eels. These groups were well distinguished during the first sampling period but some overlaps appeared in the second one. Fluctuations of static allometry and similarity coefficients showed successive glass eels arrivals in the lower part of the estuary during the two seasons. We used fluctuations of the index of similarity in the second period to describe arrivals of glass-eels...

Marine larval past of glass eel Anguilla anguilla migrating in the Adour estuary
Provedor de dados: 5
Autores: De Casamajor, Marie-noelle; Lecomte-finiger, R; Prouzet, Patrick.
Along biometric characteristics, glass eel otoliths were collected during three migration seasons, in the Adour estuary, during the new moon of January. Microstructure reading and measurements of various growth zones bring information on glass eel larval life during their oceanic migration and the transition phase in estuary. The results show significant inter-annual variations of glass eels otolithometric characteristics from the point of view of their typology as of the various growth zones measured during transoceanic migration. The differences observed between the years on the typology level could be related to very fluctuating environmental conditions during recruitment. The differences in measurements carried out on the registered otolith zones would...

Première approche de la dynamique d'une population de Temora Longicornis O.F. Müler (Copepoda, Calanoida) dans les bassins à flot du port de Dunkerque (France)
Provedor de dados: 5
Autores: Brylinski, Jm.
The wet docks of Dunkirk are 3 to 4 degrees Celcius warmer than the seaboard waters of the North Sea. Such warmth is due to thermic industrial was­te mainly from the E.D.F. power-station. A thermic and saline stratification can be observed that favours heterogeneousness among the populations of Temora lon- gicomis. The samples of copepods taken from the North Sea are significantly bigger than those found in the port of Dunkirk. Differences in size vary in the course of the year. The action of high temperatures upon reproduction is being debated j so is the existence of an autochtonous population in the docks in sum­mer.

During the hypotremata (l) study undertaken while we were in Morocco (1959-1967), we happened upon large batches of Raja clavata Linné, 1758. The abundance of the material thus made available to us prompted us to study a little more closely this species that is very widely dominant between -150 and -200m on the Casablanca continental shelf.

Relations biométriques chez l'araignée de mer Maja squinado : longueur de référence, distinction juvénile-adulte, taille-poids.
Provedor de dados: 5
Autores: Le Foll, Didier; Latrouite, Daniel; Noel, Philippe.
For the analysis of spider crab populations it is necessary to split the size composition by sex and between age groups, and to convert length to weight. In some cases different length measurements need to be correlated in order to compare the results from different authors. Morphometricaly it is easy to use the abdominal flap to distinguish between male and female, and between immature and adult females, but for immature and adult males it is necessary to use Somertons method to analyse the relation between carapace length and claw width. The relation between carapace length and weight is normally established at moult stage 4, and it obtained separately for males, females, immature and adults spider crabs. When measuring carapace length the present length...

Autores: Pouvreau, Stephane; Davenel, A; Quellec, S; Rambeau, M.
Nuclear Magnetic Resonance (NMR) is increasingly used in biology and the appearance of imaging and structural and/or metabolic spectroscopy (MRI/MSR) platforms (Rennes, Strasbourg, Marseille...) devoted to this small animal shows the recent keen interest in these research techniques. However, to this day and to our knowledge, no approach of this style has been developed for sea molluscs and even less so for the cup oyster, Crassostrea gigas. Because of its economic importance, this bivalve mollusc is the subject of much research in physiology, to the point of becoming, at IFREMER, a biological model for marine invertebrates. Nonetheless, most of the methodologies developed for studying it are destructive, which (1) prevents individual follow-up, (2)...

Pêche de la langouste rouge Palinurus elephas en france. Eléments pour fixer une taille marchande
Provedor de dados: 5
Autores: Latrouite, Daniel; Noel, Philippe.
From the end of XIX century to the 1950', spiny lobster (Palinurus elephas) fishing has been an important economical activity for potters of Brittany and led to landings over two thousands tons. Later, impoverishment of traditional fishing grounds and closure, to French fleet, of foreign fishing area obliged a reconversion of potters toward crabs (edible crab and spider crab). Recently in the 80', development of a netting activity has restarted catches of spiny lobster (at a modest scale). Presently, the only reglementary measure concerning this species/metier is a national minimum legal size (total length) but European Commission has wished that a European MLS would be established. In that aim, this paper presents the main features of spiny lobster...

Etude morphologique du loup Dicentrarchus labrax L. de la region de Sete
Provedor de dados: 5
Autores: Barnabe, Gilbert.
Sampling of a population of D. Labrax was one with spear diving catches. Morphometric and meristic data were used to calculate a biometric index. This index showed that all the bass of the Sete area belong to Dicentrarchus labrax, even if they were black spotted on the upper part of the body. Morphology was slightly different according to sex, but sex determination was not always possible using morphometric data. This inshore population shows some morphological characteristics (branchiospine and lateral line scale number) different from the data collected on the same sp along the Maroc Atlantic coast by Gravier, 1961.

Autores: Quignard, J.p; Hamdouni, T; Zaouali, J.
Researchers have studied the number of rays in the dorsal and anal fins, the number of branchiospines and of vertebrae of the anchovies of the Tunisian coast. Regarding the number of vertebrae, the anchovies of the North West belong to the 'West Mediterranean' group and those of the North East and South East to the 'East Mediterranean' group, according to Fage's classification. The anchovies found in Lake Ishkeul are well individualised morphologically and biologically speaking and could be classified in the large group of the anchovies living in Mediterranean brackish waters; the number of their vertebrae is slightly inferior to that of the groups living in the neighbouring sea waters.

The change of animal biometrics (body mass and body size) can reveal important information about their living environment as well as determine the survival potential and reproductive success of individuals and thus the persistence of populations. However, weighing individuals like marine turtles in the field presents important logistical difficulties. In this context, estimating body mass based on body size is a crucial issue. Furthermore, the determinants of the variability of the parameters for this relationship can provide information about the quality of the environment and the manner in which individuals exploit the available resources. This is of particular importance in young individuals which growth quality might be a determinant of adult fitness....

On the occurrence and identity of triploids of Rana kl. esculenta Linnaeus and R. lessonae Camerano in The Netherlands (Anura: Ranidae)
Provedor de dados: 16
Autores: Blommers-Schlösser, Rose M.A.
According to electrophoresis and erythrocyte size the genotypes of 756 waterfrogs, collected during 1986—1988 in 54 localities in The Netherlands, were classified as belonging to 5 different genotypes: 331 diploid R. lessonae (LL), 5 triploid R. lessonae (LLL), 250 diploid R. kl. esculenta (LR), 133 triploid R. kl. esculenta (LLR), and 37 diploid R. ridibunda (RR). The occurrence of triploid R. kl. esculenta in The Netherlands is reported for the first time and triploid R. lessonae has not yet been reported previously. There are indications that LL gametes could be produced by LLR triploids and LL diploids. R. kl. esculenta in R. kl. esculenta and R. ridibunda — R. kl. esculenta populations of the western regions seems to be exclusively triploid, whereas...

Non-Destructive Model to Predict Commelina diffusa Leaf Area
Provedor de dados: 87
Autores: CARVALHO,L.B.; ALVES,E.A.; BIANCO,S.
ABSTRACT: Leaf length (L), leaf width (W), and leaf area (LA) were measured from 100 leaves aiming to determine a simple linear equation (Y=a*X) to predict the leaf area of Commelina diffusa, an important weed infesting annual and perennial crops in Brazil and worldwide. Results indicate the equation LA=0.7*LW reliably estimates the leaf area of C. diffusa, after correlating LA with LW, and then validating that equation by analyzing four new 25-leaf samples.

ABSTRACT  Brazil is the third largest fruit producer in the world, but many native fruits remain underexploited, as is the case for mangabeira (Hancornia speciosa Gomes). Little is known about general aspects of this species in its naturally occurring environment. Thus, this study aimed to characterize plant and fruit morphologies from native mangabeira selections in the Savannah-Restinga vegetation transition zone. The experiment was carried out in Patizal, Recanto and Recurso villages located in the Morros municipality, Maranhão State, dominated by extensive Savannah-Restinga vegetation transition zone with naturally occurring mangabeiras. Forty five mangabeira trees were randomly chosen from native selections in the three villages. Data collected were...

The aim of this study was to compare the genetic diversity of 12 populations of goats in Brazil and Morocco (n = 796) through the use of physical measurements and different multivariate techniques. Traits measured included wither height (WH), distance from the brisket to the ground (BH) and ear length (EL). The standardized Euclidean distance (D) was adopted. The D values were submitted to clustering analysis using hierarchical methods (from nearest neighbor and UPGMA - Unweighted Pair Group Method with Arithmetic Mean) and the numbers of clusters were analyzed using the Tocher optimization method. The population clustering was different depending on the method of analysis used. Among the hierarchical methods, UPGMA showed the best fit (CCC = 0.82). The...

Provedor de dados: 63
Autores: Posse,Robson Prucoli; Sousa,Elias Fernandes de; Bernardo,Salassier; Pereira,Messias Gonzaga; Gottardo,Romildo Domingos.
Leaf area estimation is an important feature in physiological research involving predominantly photosynthesis, transpiration and growth. This study was carried out to develop a practical and nondestructive empirical mathematical model to estimate the area of one leaf and the total leaf area for papaya trees (Carica papaya L.). Two irrigated commercial orchards were evaluated over a period of 50 to 550 days after transplanting, during which the length of the leaf midrib (LM) varied from 0.04 to 0.60 m. A mathematical model was developed to estimate the area of one leaf for the papaya tree, taking into account LM and the age of the plant measured in days after transplanting. The model was considered satisfactory. Based on the average length of the last two...

Provedor de dados: 39
Autores: Bicalho,Elisa Monteze; Rosa,Bruno Luan; Souza,Anna Elisa de; Rios,Camilla Oliveira; Pereira,Eduardo Gusmão.
ABSTRACT Fire is an abiotic disturbance that regulates vegetation structure and biodiversity. Some plant species have adapted to fire prone environments by evolving protective structures. Acrocomia aculeata (macaw palm) is widely distributed throughout tropical America, and is found in environments continuously influenced by anthropogenic fire. We aimed to determine whether the fruit characteristics of A. aculeata enable seeds to resist the effects of fire and also the consequent effects of fire on fruit biometric traits and embryo viability. After a fire event in a region of pasture-forest transition, we marked 30 individuals of A. aculeata. The trees were separated by UPGMA analysis into 5 groups according to fire exposure, ranging from trees with no...

Body weight-length relationships in giant otters (Pteronura brasiliensis) (Carnivora, Mustelidae)
Provedor de dados: 52
Autores: Rosas,Fernando César Weber; Rocha,Carla Soares da; Mattos,Gália Ely de; Lazzarini,Stella Maris.
Few giant otters (Pteronura brasiliensis) have been measured and weighed and its actual size is controversial in the literature. This study presents the weight-length relationship of Amazonian giant otters using 15 captive individuals. The maximum length and weight were 163cm and 22.5kg, and 162cm and 28.8kg, for the males and females, respectively. The weight-length relationships were not significantly different between the sexes (t = 0.658, d.f.=11, P&gt;0.05) and can be expressed by the equation: W=1.48x10-5 L2.81. Considering that some of the giant otters used in this study were old individuals (more than 10 years old), and that all the animals analyzed were healthy, it is possible to assume that the weight-length relationships obtained are probably a...
