Tilapia is the most economically important fish in the aquaculture of different countries from the Americas. This species exhibits morphological plasticity under different conditions. In this study, we used landmark-based geometric morphometric to describe the shape variation of two red and one Nile tilapia farmed populations in Colombian Andes. We recorded significant morphological differences between all studied farms (P < 0.001, in the multivariate analysis of variance). In this way, individuals from the Nile tilapia farms were more elongated and had a more ventral position of the posterior extreme of the orbit and the insertion of pectoral fin than red tilapias. Moreover, the Nile group showed a shorter space between the mouth profile and the posterior extreme of the orbit, compared to red groups. On the other hand, individuals from farm red 2 were deep bodied and had a smaller head compared to tilapias from farm red 1. Our results provide evidence that tilapias from different farms in Colombian Andes display differences in body shape, and can be applied to selective breeding programs after establishing the contribution of genetic and environmental effects on tilapia shape as well as the preferences of consumers for the body shape of the species.

Chaetoceros muelleri is one of the most widely used microalgae species in aquaculture in northwestern Mexico as food for fish and crustaceans. Its importance is due to its fast growth, nutritional quality and lipid accumulation under nutrient-limiting conditions. However, the biochemical and molecular mechanisms of uptake of phosphorus (P) limiting conditions for this species is still unknown. This study aimed to analyze the growth and biochemical composition of C. muelleri in response to different phosphorus concentrations. Four treatments under different phosphorus conditions were used: control (72 μM P), excess (144 μM P) and two treatments with phosphorus limitation, limited A (18 μM P) and limited B (7 μM P). The highest cell concentration was observed in control and excess of P (>3.4×106 cells mL-1). The highest dry mass concentration and chlorophyll-a content were found in control medium (72 μM P) whereas the highest total lipid (4.42%) was found in the lowest P-concentration medium (7 μM P). No significant differences were found in the total protein content, but we did find differences between the treatments with phosphorus limitation (7 and 18 μM P).

This paper reports the occurrence of Aphrogenia alba in Potiguar Basin, northeastern Brazil. The specimen was sampled at a depth of 180 m off the Rio Grande do Norte coast in the muddy bottom. This new record extends, after 37 years, the known geographic distribution of the species in the Brazilian coast, which had previously been recorded between Rio de Janeiro (Cabo de São Tomé and Ilha Grande) and Rio Grande do Sul.

The Beast, The journey of Central American migrants on their way to the border of Mexico and the United States tells the story of undocumented migrants who travel in La Bestia, a freight train in which Central American migrants are assembled in Arriaga, Ixtepec or Ciudad Hidalgo in southern Mexico that will take you to nearby Mexicali, Nogales, Ciudad Juarez, Piedras Negras or Nuevo Laredo. Moored precariously from the roof of the train, this risky road of more than 3,000 km will determine that many of those who undertake the trip, never reach the border.

A group of jews from different origins are shut-in a barrack of Auschwitz. They are aware that they will be executed in a gas chamber at dawn. Confronting their somber destiny, they wonder why Jehova doesn´t help them. Someone accuse God for having broken the alliance with the jew people. The debate acquires the form of a judjement to God, so as to determine if he is guilty or innocent of betrayal to the Chosen People.&nbsp;God on trial&nbsp;staged the problem of the position of man confronted to horror, cruelty and injustice. But above all to the figure of God, and the varied possible respons –denial, cinical, despare, étical- in the face of it´s absence.

In 2017, the audiovisual content platform Netflix presents She’s Gotta Have It, a story based on the Spike Lee film filmed in 1986, both of them share the name and the director. We will work some questions of the first season that consists of ten chapters, of approximately thirty minutes each, with an adapted script. Nola Darling returns; black woman, activist and artist who lives in Booklyn, and finds herself permanently searching her own identity. In this journey, her aspiration in the profession and the events that name her as a woman coincide. Nola resists all alienation to a name, and it is sustained by multiplying the others that it invents. This solution is not enough when it comes to addressing the real traumatic event. Thedirector shows us the contrast between a neighborhood full of identity references, with its images, its films, its discs and a woman who idealizes the feminine black form, to the point that whenever something represents it, it is not. In the Rashomon (Jingo, 1950) mode everyone looks at it from a perspective, but there is no finished form. Nola knows that there Woman does not exist, but believes in her and creates a way to make her exist, without naming her, without being her.

The “Wonderful Disney World”, from its Princesses, proposes female stereotypes as possible answers to the Freudian question about what a woman wants. From the first appearance to the present, these princesses were modifying their positions and countenance, according to the discourse of the prevailing master. In the same way their relationship to men was transformed, and the place they give to love. Since the 30s, with the model of mother and housewife, going through the 60s with sexual liberation, and the first feminist movements, to the present where feminisms take center stage, women were reinventing themselves, and with it their ties , to the other, and consequently to the Other.
