An independent state in the Lesser Antilles in the West Indies, north of Venezuela, comprising the islands of Trinidad and Tobago. Its capital is Port of Spain. Both islands were discovered by Columbus in 1498. The Spanish, English, Dutch, and French figure in their history over four centuries. Trinidad and Tobago united in 1898 and were made part of the British colony of Trinidad and Tobago in 1899. The colony became an independent state in 1962. Trinidad was so named by Columbus either because he arrived on Trinity Sunday or because three mountain peaks suggested the Holy Trinity. Tobago was given the name by Columbus from the Haitian tambaku, pipe, from the natives' habit of smoking tobacco leaves.

Figure 3 - Phenogram of overall molecular similarity of RAPD bands among specimens from all localities at Tibagi, Paraná, and Iguaçu Rivers. Codes as in Figure 1. DISCUSSION The RAPD-PCR patterns indicate strong genetic differentiation within and among populations in the Paraná and the Tibagi Rivers. In the Paraná River at Porto Rico, the high levels of allelic polymorphism may represent the pristine composition of different species or populations within the H. malabaricus species complex, or they may be the outcome of faunal mixing caused by the closing of the Itaipu Dam in 1978 and the consequent flooding of Sete Quedas, another Oligocenic geographic barrier (Sampaio, 1988). Sete Quedas was the natural boundary for the Upper and Middle Paraná basins. The presence of an outlier in the Paraná River similar to the Iguaçu population suggests that the Paraná may indeed be a recipient of trahiras of diverse origins. The Londrina sample from the Tibagi River is most similar to the populations ...
The FIS values for each subpopulation tested by the formulae of Li (1955) were significantly different from zero (P , 0.05) at the EST-1*, EST-2* and PGM-2* loci from the Paraná river subpopulation, exactly the loci in which bands had low definition. The FIT values for EST-1* and EST-2* were significantly different from zero (P , 0.05) using the method of Brown (1970). None of the FST values tested by the procedures of Workman and Niswander (1970) were significantly different from zero (P , 0.05). DISCUSSION The levels of genetic variability and polymorphism reported in this study for the curimba can be considered high when compared to the mean values obtained by Nevo (1978) for 51 teleost species (H = 0.051 and P = 0.152) or the mean heterozygosity values calculated by Powell (1975) and Ward et al. (1992) for marine and freshwater fishes (0.058 and 0.051, respectively). High levels of heterozygosity and polymorphism might be expected for species of fish occurring over a broad range of ...
Triploidy in tambaqui Colossoma macropomum identified by chromosomes of fish larvae is an article from Journal of Aquaculture & Marine Biology for MedCrave Group. Triploid fish are excellent models for use in commercial scale because they can show higher rates of growth, carcass yield and meat quality. If sterile, tambaqui (Colosso mamacropomum) triploids can be used to avoid the problems related to early puberty, especially the negative impacts of male sexual maturation on harvest weight. In the present study, we evaluated the triploidy induction efficiency (thermal shocks) in the fish tambaqui Colossoma macropomum, the most important Neotropical species used for aquaculture. To verify the result of the triploidy experiments, we used a protocol of ploidy identification through analysis of mitotic chromosomes of early life stages (larvae cytogenetics). We obtained better results of hatching and triploid rates through temperature shock at 41°C for 2 min (heat shock) than cold shock. In conclusion,

Etymology: Erimystax: Greek, eri = aumentative prefix, a lot + Greek, mystax = moustache (Ref. 45335); insignis: From the words eri, an intensifying prefix; stigma, spot; and insignis, meaning remarkable (referring to the distinct pigment pattern) (Ref. 10294). ...
The anomalures, including Z. insignis, are unique among rodents in having a set of scales on the ventral surface of the base of the tail.[5] These scales reportedly provide traction when climbing trees.[2][3] Z. insignis is the only anomalure that lacks patagia (membranes that span between the forelimbs and hindlimbs).[2][3] Anomalures that possess patagia are able to glide between trees. Thus, Z. insignis is unable to glide. The divergence of the Z. insignis lineage from other extant anomalures apparently occurred before the evolution of anomalure gliding.[5] Gliding is a relatively rare adaptation that has independently evolved in three lineages of extant placental mammals (anomalures, colugos, and flying squirrels).[12] Z. insignis has ashy-grey pelage and bushy black tail hair.[3][5] Tufts of short, course, and spikey hairs are located on the lateral ankles.[3][5] The hands and feet have four and five digits respectively.[3][5] Pedal digit I (the first toe) is somewhat divergent.[5] Z. ...
With this new technique, it is possible to obtain new information thanks to the project carried out by four UNal-Medellín graduate students directed by School of Biosciences Professor Edna Judith Márquez Fernández. To amplify DNA regions, the researchers developed specific sequences known as primers which help observe population genetic variations of fish of the medium and low basins of the Cauca River, between the municipality of Tarazá and the outpour of this river into the Magdalena River. The method accurately analyzes the genetic diversity of 13 migratory species: jetudo or pataló (Ichthyoelephas longirostris), ray-finned fish (Prochilodus magdalenae), vizcaína (Curimata mivartii), dolphin catfish (Ageneiosus pardalis), trans-Andean shovelnose catfish (Sorubim cuspicaudus), chango or mueluda (Cynopotamus magdalenae); capaz (Pimelodus grosskopfii), arenca (Triportheus magdalenae), sabaleta (Brycon henni), four-lined pimodella (Pimelodus blochii), stripped catfish (Pseudoplatystoma ...
Hi ... a small post to show you the amazing power of regeneration in piranha (Pygocentrus Piraya) video that could not have more information (Japanese owner) I
Hypothesizing that the Amazonian water system differences would affect the expression of muscle growth-related genes in juvenile tambaqui |i|Colossoma macropomum|/i| (Cuvier 1818), this study aimed to analyze the morphometric data and expression of myogenic regulatory factors (MRFs) in the white and red muscle from tambaqui obtained from clear and black Amazonian water systems. All of the MRF transcript levels (|i|myod|/i|, |i|myf5|/i|, |i|myogenin|/i|, and |i|mrf4|/i|) were significantly lower in the red muscle from black water fish in comparison to clear water fish. However, in white muscle, only the |i|myod|/i| transcript level was significantly decreased in the black water tambaqui. The changes in MRFs gene expression in muscle fibers of tambaqui from black water system provide relevant information about the environmental influence as that of water systems on gene expression of muscle growth related genes in the |i|C. macropomum|/i|. Our results showed that the physical and chemical water

The Piranha Unmanned Surface Vessel (USV or unmanned surface vehicle) is a watercraft developed by Zyvex Marine (a division of Zyvex Technologies, formerly Zyvex Performance Materials) in 2010. The boat is 54 in length and weighs just 8,000 lbs. The Piranha is the first USV to utilize a lightweight carbon-nanotube enhanced composite material called Arovex, which allows the watercraft to weigh significantly less than any other USV. The weight advantage from Arovex gives the Piranha a payload capacity of 15,000 lbs and a range of over 2,500 miles. Additionally, the carbon-nanotubes actually provide a strength increase of 20-50% over traditional materials. With those characteristics, the Piranha is expected to be sold as a possible tool for anti-piracy, search and rescue, submarine hunting, and harbor patrol. The first Piranha began construction in February 2010 with an anticipated completion date of summer 2010. The Piranha underwent sea trials near Seattles Puget Sound during the months of ...
Nitrogen metabolism in tambaqui (Colossoma macropomum), a neotropical model teleost: hypoxia, temperature, exercise, feeding, fasting, and high environmental ammonia.. PubMed. Wood, Chris M; de Souza Netto, José Gadelha; Wilson, Jonathan M; Duarte, Rafael M; Val, Adalberto Luis. 2017-01-01. The total rate of N-waste excretion (M N) in juvenile tambaqui living in ion-poor Amazonian water comprised 85 % ammonia-N (M Amm-N) and 15 % urea-N (M Urea-N). Both occurred mainly across the gills with only ~5 % of M Amm-N and ~39 % of M Urea-N via the urine. Tambaqui were not especially tolerant to high environmental ammonia (HEA), despite their great resistance to other environmental factors. Nevertheless, they were able to maintain a continued elevation of M Amm-N during and after 48-h exposure to 2.5 mmol L(-1) HEA. The normally negative transepithelial potential (-18 mV) increased to -9 mV during the HEA period, which would help to reduce branchial NH4(+) entry. During 3 h of acute environmental ...

The structural characterization of the olfactory epithelium in Pygocentrus nattereri Kner, 1858 was studied with the help of light as well as scanning and transmission electron microscope. The oval shaped olfactory rosette consisted of 26-28 primary lamellae radiated from midline raphe. The olfactory epithelium of each lamella was well distributed by sensory and non-sensory epithelium. The sensory epithelium contained morphologically distinct ciliated and microvillous receptor cells, supporting cells and basal cells. The non-sensory epithelium was made up of labyrinth cells, mucous cells and stratified epithelial cells. According to TEM investigation elongated rod emerging out from dendrite end of the receptor cells in the free space. The dendrite process of microvillous receptor cells contained microvilli. The supporting cells had lobular nucleus with clearly seen electron dense nucleolus. The apex of the ciliated non-sensory cells was broad and provided with plenty of kinocilia. Basal cells ...

Devario coxi is similar to D. aequipinnatus in color pattern, with distinct P+1, P and P stripes along the side, but P and P-1 stipes confluent anteriorly and containing light spots (vs. integer to close to pectoral girdle, and interstripe I integer except occasional interruption anteriorly). It differs from D. aequipinnatus by the combination of having more branched dorsal- fin rays (11½±12½ vs. 9½±10½, exceptionally 11½), more circumpeduncular scales (14, vs. 12, rarely 14); slightly deeper body (body depth 29.9±33.2 vs. 26.7±30.8% SL), and shorter upper jaw (upper jaw length 8.3±9.3 vs. 9.2±12.0% (SL). It is distinguished further from striped species of Devario in southern and south-western India, D. fraseri, D. malabaricus, D. mysoricus, and D. neilgherriensis by having infraorbital process vs. absent (Ref. 116720). ...

Ultrastructural analyses of fish-infecting myxosporean Henneguya piaractus that is found in the gill lamellae of the freshwater teleost Piaractus mesopotamicus (Characidae) and collected from the Paraguai River, Brazil were described. The parasite occurs within large whitish spherical to ellipsoidal polysporic cysts (up to 2.5 mm long) delimited by a layer of fibroblasts generally connected with some capillaries on the gill epithelium. No external morphological signs of disease were visible in the infected fishes. The tailed spores measured 61.5 ± 0.91 (60.2-62.6) μm in total length and ellipsoidal spore body 21.1 ± 0.62 (20.6-21.9) μm long, 6.7 ± 0.40 (6.2-7.3) μm wide and 2.5 ± 0.54 (2.0-3.1) μm thick. The spore wall was about 97 nm of thickness and consisted of a thin electron-dense exospore and a thick electron-lucent endospore with about 85 nm of thickness. The tailed spores were composed of two equal-sized shell valves adhering together along the straight suture line each having in ...
The freshwater fish louse Dolops carvalhoi is an ectoparasite of pacu, Piaractus mesopotamicus capable of causing substantial damage to its hosts. The aim of this study was to investigate some aspects of the host-parasite interaction between these two species. For this purpose the physiological and morphological responses and the participation of the non-adaptive immune system of pacu to the experimental infestation with D. carvalhoi were analyzed. Three different experimental protocols were designed in order to find out the effects of the parasites on their hosts, the host responses that may interfere with parasite establishment and the influence of chronic exposure of hosts with juvenile D. carvalhoi to a second acute stressor of confinement. The results showed that even low level of adult parasite infestation is capable to induce a stress response in the hosts. No changes were observed regarding the plasma osmoregulatory parameters, while an increased number of gill chloride cells and ...
The composition of the diet, the metabolic adaptations and variations in the activity of the fish are the main factors responsible for seasonal changes in physiological variables. It is known that aerobic exercise can improve the fish growth due to: the enhancement of feed conversion, reduced dominance, increased protein synthesis and lipid and glucose catabolism. The diet must satisfy the nutritional requirements of each species. Knowledge of the appropriate protein level is critical because maximizes feed conversion efficiency, lowers costs and reduces the load of nutrients released to the aquatic ecosystem. In Brazil, the pacu, Piaractus mesopotamicus, is an important fish in aquaculture, especially for hardiness, fast growth, excellent meat quality. This species may respond to exercise with lower levels of protein catabolism and for directing them to growth. Thus, a balanced diet and a well established aerobic exercise protocol could promote better growth for pacu. This study aimed to ...
In seasonal mammals living in temperate zones, photoperiod regulates prolactin secretion, such that prolactin plasma concentrations peak during the summer months and are lowest during the winter. In sheep, a short-day breeder, circulating prolactin has important modulatory effects on the reproductive system via inhibitory actions on pituitary gonadotrophs and hypothalamic gonadotrophin-releasing hormone release. The exact cellular mechanisms that account for the chronic hypersecretion of prolactin during the summer is not known, although evidence supports an intrapituitary mechanism regulated by melatonin. Folliculo-stellate (FS) cells are non-endocrine cells that play a crucial role in paracrine communication within the pituitary and produce factors controlling prolactin and gonadotrophin release. The present study examined the morphology of the FS and lactotroph cell populations and their distribution in the sheep pituitary during the annual reproductive cycle. Ovine pituitary glands were collected in

Abstract: About 650 species-330 snakes, 230 lizards, 50 amphisbaenids, 6 caimans, and 35 turtles-comprise the known reptile fauna of Brazil. Only 20 are considered threatened. Except for the marine and freshwater turtles, which suffer from overexploitation and habitat destruction, they are threatened because of their rarity and extremely restricted ranges. Despite its richness and diversity, research on Brazils reptile fauna is still largely restricted to alpha taxonomy. Surveys, an electronic database of all herpetological collections, and phylogeographic studies based on molecular genetic techniques are needed to improve our understanding of the biogeography of this group and to delineate effective conservation strategies to preserve the evolutionary potential of existing lineages. Autecological, population, and community studies that monitor effects of habitat degradation, fragmentation, and loss, pollution, and exploitation are needed for a better understanding of the effects of the ...

Bothrops marajoensis is found in the savannah of Marajo Island in the State of Par S and regions of Amapa State, Brazil. The aim of the work was to study the renal and cardiovascular effects of the B. marajoensis venom and phospholipase A(2) (PLA(2)). The venom was fractionated by Protein Pack 5PW. N-terminal amino acid sequencing of sPLA(2) showed amino acid identity with other lysine K49sPLA(2)s of snake venom. B. marajoensis venom (30 mu g/mL) decreased the perfusion pressure, renal vascular resistance, urinary flow, glomerular filtration rate and sodium tubular transport. PLA(2) did not change the renal parameters. The perfusion pressure of the mesenteric bed did not change after infusion of venom. In isolated heart, the venom decreased the force of contraction and increased PP but did not change coronary flow. In the arterial pressure, the venom and PLA(2) decreased mean arterial pressure and cardiac frequency. The presence of atrial flutter and late hyperpolarisation reversed, indicating ...
Brazil, officially the Federative Republic of Brazil is the largest country in both South America and Latin America. As the worlds fifth-largest country by area and sixth by population, it is the largest country to have Portuguese as an official language and the only one in the Americas. Bounded by the Atlantic Ocean on the east, Brazil has a coastline of 7,491 kilometers (4,655 mi) It borders all other South American countries except Ecuador and Chile and covers 47.3% of the continents land area. Its Amazon River basin includes a vast tropical forest, home to diverse wildlife, a variety of ecological systems, and extensive natural resources spanning numerous protected habitats. This unique environmental heritage makes Brazil one of 17 megadiverse countries, and is the subject of significant global interest and debate regarding deforestation and environmental protection. ...
Accurate and detailed species distribution maps are fundamental for documenting and interpreting biological diversity. For snakes, an ecologically diverse group of reptiles, syntheses and detailed data on distribution patterns remain scarce. We present the first comprehensive collection of detailed, voucher-based, point-locality, range maps for all described and documented Brazilian snakes, with the major aim of mitigating the Wallacean shortfall and as a contribution towards a better understanding of this rich, threatened, and poorly studied megadiverse fauna. We recorded a total of 412 snake species in Brazil on the basis of an extensive and verified point-locality database of 163,498 entries and 75,681 unique records (available here as Online Supporting Information). Our results reveal previously undocumented patterns of distribution, sampling effort, richness, and endemism levels, resulting in a more objective view of snake diversity in the Neotropics. Apart from these achievements, we ...
excerpted from the INTRODUCTION: The Dominance of Diptera Most species of animals belong to one of four large orders: the Coleoptera (beetles), Lepidoptera (moths and butterflies), Hymenoptera (ants, wasps, bees and sawflies) or Diptera (flies). Of these megadiverse groups, the flies are arguably the most important, if only because they kill millions of people a year by transmitting our most devastating diseases. But this enormous impact is due to only a few dozen species, and dipteran damage to forests, crops and stored products is similarly due to mere dozens of different fly genera. Vastly more -- thousands of species -- are beneficial, contributing to the pollination of plants, biological control of pest insects, and disposal of the dung, carrion and other organic matter that would otherwise quickly carpet the planet. Despite all this, a relatively large proportion of the species in the order Diptera remains undiscovered, unnamed or unidentifiable. This is perhaps in part because of the ...
The popular image of red-bellied piranhas portrays them as more feared than fearful. However, the results of our investigation are consistent with an anti-predator function for shoaling in the species. We found that opercular rate, which typically increases under risk (Metcalfe et al. 1987; Barreto et al. 2003), and may be indicative of a fishs preparedness to flee (Hawkins et al. 2004), was lower in larger groups, even in the absence of an overt predation threat. Furthermore, after a simulated attack, opercular rate remained elevated for longer in the smaller shoals. Because the size of red-bellied piranha shoals at Mamirauá ranges from fewer than 10 to about 100 (H. Queiroz and A. E. Magurran, personal observation), the grouping advantages detected in this experiment are applicable to fishes in the wild. Our study not only casts new light on the behaviour of a charismatic, though poorly researched species, but also reveals how a fishs perception of risk is affected by shoal size.. In the ...

The world's major fish faunas, and most of its smaller ones as well, are by no means well-known, either taxonomically or with regard to the biology of their component species. Apart from the very large number of fish species (20,000-27,000) and the difficulties for study posed by the medium in which they live, there are several other reasons for that state of affairs. An obvious and universal reason is the shortage of money available for fundamental research, and consequently a shortage of research workers. In the fields of taxonomy and systematics, both basic and essential disciplines in the study and interpretation of biodiversity, that shortage is exacerbated by other and supposedly more exciting and glamorous disciplines attracting students and teachers (and funds!). The biology of most species is poorly known, if at all, and even for those fishes of economic importance it is often biased towards particular and pragmatic ends. Fishes, no less than other organisms, are threatened by numerous
Theres no denying that James Cameron is a talented man in this industry and he has made a few of the greatest innovations in recent years (notably further exploring the Titanic and the current 3D technology.) Though his script writing talents are questionable and aspects of his directing are suspect Cameron seems to have an uncanny ability to pull great work from his actors, but his biggest talent may not be as a director. Cameron is likely one of the greatest cinematographers thats not working as one. With all due respect to the cinematographers whove worked with him (though there are numerous rumors that speak to Cameron being extremely difficult to work with) his films all have a stunning beauty that remains constant though his director of photography may not. Piranha Part 2: The Spawning may not be a grand sprawling epic that Cameron will become known for but inklings of that talent are evident to the keen observer. His work with underwater scenes are surprisingly good (hes an avid and ...

There currently exist a dozen described Esomus specie,s although few are seen in the ornamental trade and none are especially popular. Most are commonplace in their native countries but are generally overlooked by collectors due to their relatively plain colouration. Their most common use in some areas is actually as a feeder fish in the aquaculture of larger species. They are characterised by greatly-enlarged pectoral fins and two pairs of barbels, of which the maxillary pair are extremely long and usually reach the pectoral fins.. In recent years a number of phylogenetic studies involving Esomus and its near relatives have been conducted and conflicting results published. For example a 2003 study by Fang et al. concluded that the genus is the sister group, i.e., most closely-related to, Danio whereas Mayden et al. (2007) placed the genera Chela, Microrasbora, Devario and Inlecypris as sisters to Danio with Esomus as a basal sister group to that larger clade.. A further analysis by Fang et al. ...
Hi Colin, good to speak again, not seen you around for ages. Hows things? Luckily for me my arnoldi spawns are almost 100% fertile 99% of the time.. Its obviously a fertility problem, how old are the fish? what are they spawning on? i used to get poorer results when mine jumped to the cover glass, the gravity was a stronger pull and it seemed they always spent a second or so less when laying/fertilising the eggs than they do with my current method.. I now drop the water level a good 6 inches so stop them spawning on the coverglass, then utilise plastic/silk plants with removeable leaves, once i have a spawn(most days!) i remove the eggs along with the leaf and place them imersed in a 2 litre container where they hatch and live for the first 10 days while on paramecium.. Once on baby brineshrimp they are moved to a larger 5 litre container for a further week or so and then into a 20 litre filtered glass tank and eventually larger again as they outgrow it..A lot of work but a lot of fun and ...

The freshwater fish genus Astyanax is one of the most diverse among the Characidae. The genus is defined by a combination of character states that are widely distributed in Characidae. In addition, the genus has the broadest geographical distribution in the family, being found in a great variety of environments of the Neotropical region. Although phylogenetic relationships were treated only partially, many authors agree that the genus is not monophyletic. In this contribution, we study the phylogenetic relationships of Astyanax in the context of the family Characidae, by combining morphological and molecular data. A total of 520 morphological characters, nine molecular markers and 608 taxa are analysed, of which 98 belong to Astyanax. According to our results, Astyanax is not monophyletic. We recovered species attributed to Astyanax in different subfamilies: Gymnocharacinae (including the type species), Stevardiinae ...

Hoplias malabaricus, a widespread Erythrinidae fish, is characterized by a karyotypic diversity, with seven karyomorphs already described. This report presented a comparative study of the karyomorphs A, B, C and D, which were previously included in a major karyotypic group (Group I), in order to evaluate the evolutionary relationships among them. The in situ investigation of several classes of repetitive DNAs added new informative characters useful in comparative genomics and provided new insights into the evolutionary relationships among karyomorphs. In addition to corroborate the inclusion of karyomorphs A-D in a close evolutionary group, the results provide further evidence for a greater proximity between the karyomorphs A-B and karyomorphs C-D. A comparative analysis among distinct populations of karyomorph A demonstrated a continuing genomic differentiation in this group, allowing the detection of recent evolutionary events, suggesting that this karyomorph cannot be considered an absolute ...

Cytogenetic analyses were accomplished in two populations of Astyanax altiparanae Garutti & Britzki, 2000 and one population of Hyphessobrycon eques Steindachner, 1882, considered incertae sedis in Characidae family. Two populations of A. altiparanae (Mogi-Guaçu and Tietê rivers) presented 2n=50, with the same karyotype formula: 6M+12SM+20ST+12A (FN=88). H. eques from Capivara river presented 2n=52 and karyotype formula 14M+16SM+4ST+18A (FN=86). In each karyotype, the nucleolus organizer regions were detected at the end of the short arm of a single medium-sized subtelocentric chromosome. The Chromomycin A3 (CMA3) marking is coincident for the NORs in chromosomes of the two species and present additionally in two different chromosomes of A. altiparanae thus showing interpopulation differences in this species. In H. eques, weak heterochromatic blocks in the position of centromeres and telomeres of most chromosomes and negative C-banding for the NOR ...
