The Neotropics contain one of the most diverse assemblages of freshwater fishes worldwide. Part of this diversity is shared between the Orinoco and Amazon basins. These basins have been separated for a long time due to the Vaupes Arch, rising between 10-11 Ma. Today, there is only one permanent connection between the Orinoco and Negro (Amazon) basins, known as the Casiquiare Canal. However, alternative corridors allowing fish dispersion between both basins have been proposed. The cardinal tetra (Paracheirodon axelrodi), the most important fish in the ornamental world market, is distributed in both basins. Here we investigated P. axelrodi phylogeography, population structure, and potential routes of migration and connectivity between the two basins. A total of 468 bp of the mitochondrial gene (COI), 555 bp of the nuclear gene fragment (MYH6), and eight microsatellite loci were analyzed. As a result, we found two major genetic clusters as the most likely scenario (K = 2), but they were not discreetly distributed between basins. A gradient of genetic admixture was observed in Cucui and São Gabriel da Cachoeira, between the upper Negro River and the upper Orinoco. Samples from the middle-lower Negro River were highly structured. Cucui (Negro basin) was more similar to the Orinoco than to the rest of the Negro basin populations. However, substructure was also observed by the discriminant analysis, fixation indices and other hierarchichal structure analyses (K = 3-6), showing three major geographic clusters: Orinoco, Cucui, and the remaining Negro basin. Unidirectional migration patterns were detected between basins: via Cucui toward Orinoco and via the remaining of the Negro basin toward Orinoco. Results from the Relaxed Random Walk analysis support a very recent origin of this species in the headwater Orinoco basin (Western Guiana Shield, at late Pleistocene) with a later rapid colonization of the remaining Orinoco basin and almost simultaneously the Negro River via Cucui, between 0.115 until about 0.001 Ma. Historical biogeography and population genetic patterns observed here for Cardinal tetra, seem to be better explained by river capture, physical, or ecological barriers than due to the geographic distance.

Economic instruments are political tools created to promote environmental stewardship by influencing consumption and production patterns, fostering technological innovation, and improving the environment; however, if current failures in their formulation or implementation persist, they can negatively impact the environment and society. This research aims to analyze the strengths, weaknesses, opportunities, and threats (SWOT) of economic instruments by extracting these aspects from the forest policy documents of the EU, Austria, and the Czech Republic using the qualitative content analysis method. It has been found that the EU channels its resources from economic instruments through various financing programs that make distribution more effective and align with the environmental objectives of the EU. Additionally, the SWOT analysis indicates that the economic instruments applied in the EU present significant differences in the application and management of forests and the performance of the financial instruments according to the national strategies and action plans used. These identified challenges, limitations, and improvement areas allow for generating suggestions that policymakers can apply concerning the use, implementation, dissemination, and access processes of financing mechanisms for sustainable forest management in the European Union.

This essay arises as part of a process of conceptual and empirical exploration around the dispute and transformation of public space, both in its material and symbolic expression, through cultural practices. I have focused on those expressions that have a performative character, in consideration of the capacity of bodies to break into everyday life, produce space and generate collective presences, while constituting processes of enunciation from the differences. This is especially significant for those who have restricted access to the constitution of the public, given certain power relations that define who and what counts for a community. Based on this observation, I analyze the case of Mery Cortez Ortiz, mother of a young Ecuadorian murdered by the Army in the framework of the so-called "Chilean Social Outbreak", using bibliographic and press review.

Abstract Background Bacterial leaf blight causes significant yield losses in rice crops throughout Asia and Africa. Although both the Asian and African strains of the pathogen, Xanthomonas oryzae pv. oryzae (Xoo), induce similar symptoms, they are nevertheless genetically different, with the African strains being more closely related to the Asian X. oryzae pv. oryzicola (Xoc). Results Changes in gene expression of the African Xoo strain MAI1 in the susceptible rice cultivar Nipponbare were profiled, using an SSH Xoo DNA microarray. Microarray hybridization was performed comparing bacteria recovered from plant tissues at 1, 3, and 6 days after inoculation (dai) with bacteria grown in vitro. A total of 710 bacterial genes were found to be differentially expressed, with 407 up-regulated and 303 down-regulated. Expression profiling indicated that less than 20% of the 710 bacterial transcripts were induced in the first 24 h after inoculation, whereas 63% were differentially expressed at 6 dai. The 710 differentially expressed genes were one-end sequenced. 535 sequences were obtained from which 147 non-redundant sequences were identified. Differentially expressed genes were related to metabolism, secretion and transport, pathogen adherence to plant tissues, plant cell-wall degradation, IS elements, and virulence. In addition, various other genes encoding proteins with unknown function or showing no similarity to other proteins were also induced. The Xoo MAI1 non-redundant set of sequences was compared against several X. oryzae genomes, revealing a specific group of genes that was present only in MAI1. Numerous IS elements were also found to be differentially expressed. Quantitative real-time PCR confirmed 86% of the identified profile on a set of 14 genes selected according to the microarray analysis. Conclusions This is the first report to compare the expression of Xoo genes in planta across different time points during infection. This work shows that as-yet-unidentified and potentially new virulence factors are appearing in an emerging African pathogen. It also confirms that African Xoo strains do differ from their Asian counterparts, even at the transcriptional level.

Introduction: In Mexico and in the world, the Human Acquired Immunodeficiency Virus (HIV) is a problem that goes beyond the scope of public health, converging with psychological, social, ethical, economic, political and human rights factors, among others. Objective: to identify the relationship between knowledge about unplanned pregnancies, HIV and STIs, and sexual resilience in adolescents. Methods: The study was transversal, the population was composed of adolescents between 14 and 17 years old, students of the first semester of high school. Sampling was by cluster per group and the sample size was 250 adolescents. Results: The measurement instruments showed acceptable reliability measures. Of the adolescents surveyed, 57.2% were female, with a mean age of 15.92 (SD=.52). There was a mean of 15.24 (SD=4.32) in terms of knowledge of HIV, STIs, and unplanned pregnancies. Sexual resilience also averaged 55.25 (SD=15.50). Mann Whitney's U-test was performed, with women showing greater acceptance than men (M=3.84, SD=3.87, p<.044). Knowledge about HIV, STIs, and unplanned pregnancy was found to be related to sexual resilience (p<.05) and personal competence (p< .01). While personal competence (p< .01) and acceptance of self and life (p< .05) were significantly related to sexual resilience. Conclusion: Therefore, it is important to point out that the level of knowledge that adolescents possess in these areas will make a difference in their optimal health status and the preventive measures they employ to stay away from risks, and it is essential that they strengthen their resilience to face sexual adversity.
