Physics - Geophysics - Abstract
A multidisciplinary approach is proposed for evaluating the effects of shaking due to strong motions on the Tiber river alluvial deposits in Rome's historical centre. At this aim, a detailed 3D geological model of the Tiber river alluvial deposit has been constructed and a numerical analysis of site response was performed along two geological sections across the historical centre of Rome. The numerical models were performed in both 1D and 2D configurations assuming linear and nonlinear conditions, by applying a three component seismic input. The results show that the maximum shear strains are strongly conditioned by the layer geometries (i.e. 2D or 1D conditions) and by the soil heterogeneity. Moreover, the reliability of the maximum strains obtained by numerical modeling is discussed comparing these values respect to both the volumetric and the degradation dynamic thresholds of the considered soils., Comment: Effects of Surface Geology on Seismic Motion, Aug 2011, University of California Santa Barbara, United States.

Ananteris is a scorpion genus that inhabits dry and seasonal areas of South and Central America. It is located in a distinctive morpho-group of Buthids, the 'Ananteris group', which also includes species distributed in the Old World. Because of the lack of information on venom composition, the study of Ananteris species could have biological and medical relevance. We conducted a venomics analysis of Ananteris platnicki, a tiny scorpion that inhabits Panama and Costa Rica, which shows the presence of putative toxins targeting ion channels, as well as proteins with similarity to hyaluronidases, proteinases, phospholipases A
2 , members of the CAP-domain family, and hemocyanins, among others. Venom proteolytic and hyaluronidase activities were corroborated. The determination of the primary sequences carried out by mass spectrometry evidences that several peptides are similar to the toxins present in venoms from Old World scorpion genera such as Mesobuthus, Lychas, and Isometrus, but others present in Tityus and Centruroides toxins. Even when this venom displays the characteristic protein families found in all Buthids, with a predominance of putative Na+ -channel toxins and proteinases, some identified partial sequences are not common in venoms of the New World species, suggesting its differentiation into a distinctive group separated from other Buthids.

Resumen Introducción: Cerca de 113 hectáreas dentro de la Reserva Biológica Lomas de Barbudal (RBLB) se inundarían si se llegara a establecer el embalse de riego Río Piedras en el noroeste de Costa Rica. Ante ese impacto inevitable, la legislación costarricense requiere evaluar la pérdida de diversidad en el sitio y compensarla siguiendo el principio de equivalencia ecológica. Objetivo: Nuestro objetivo fue evaluar la pérdida de diversidad en el sitio y, valorar esta condición en una propiedad privada adyacente considerada como sitio potencial para compensar por esas pérdidas. Metodología: La diversidad, composición y prioridad de conservación de plantas vasculares, fauna vertebrada y artrópodos del sotobosque fueron evaluadas en el sitio de inundación en RBLB y en una propiedad privada adyacente identificada como sitio potencial de compensación. La equivalencia en diversidad entre ambos sitios se valoró mediante un procedimiento que asigna puntajes a los diferentes indicadores del sitio de compensación respecto a los observados en RBLB. La suma de esos puntajes representa la condición de diversidad del sitio de compensación y puede utilizarse como criterio para fundamentar acciones resarcitorias. Resultados: Todos los grupos sustitutos registraron un alto número de especies, aunque la información aportada por las plantas herbáceas, los mamíferos no voladores y los reptiles fue limitada. En contraste, los otros grupos indican una mayor diversidad en el sitio potencial de inundación, atribuida a sutiles diferencias ambientales y a su mejor conservación. En consecuencia, se valoró sustituir el área afectada por un área mayor del sitio de compensación para resarcir las perdidas en diversidad estimadas. Conclusión: Nuestro análisis muestra que grupos sustitutos pueden ser empleados en estudios ambientales a corto plazo. Sin embargo, los grupos a utilizar deben seleccionarse cuidadosamente, considerando los objetivos y el alcance del proyecto. Cuantificar la condición de diversidad del sitio de compensación respecto a la que se encuentra en un sitio de referencia parece ser un procedimiento válido, repetible y evaluable que permite establecer criterios sobre los cuales basar medidas resarcitorias. Abstract Introduction: About 113 hectares within the Lomas de Barbudal Biological Reserve (RBLB) would be flooded if the Río Piedras irrigation reservoir were established in northwestern Costa Rica. Given this inevitable impact, Costa Rican legislation requires evaluating the loss of diversity in the site and compensating for it following the principle of ecological equivalence. Objetive: Our goal was to assess the loss of diversity at that site and evaluate the condition of an adjacent private property as a potential site to compensate for those losses. Methodology: The diversity, composition, and conservation priority of vascular plants, vertebrate fauna, and understory arthropods were assessed at the RBLB flood site and on an adjacent private property identified as a potential offset site. The equivalence in diversity between both sites was evaluated by assigning scores to the different indicators at the compensation site concerning those observed in RBLB. The sum of these scores represents the diversity condition of the compensation site and can be used as a criterion to support compensatory actions. Results: All surrogate groups recorded a high number of species, although the information provided by herbaceous plants, non-flying mammals, and reptiles was limited. In contrast, the other groups indicate a greater diversity in the potential flood site, attributed to subtle environmental differences and the better conservation at this site. Consequently, it was assessed to replace the affected area with a larger offset site area to compensate for the estimated losses in diversity. Conclusion: Our analysis shows that surrogate groups can be used in short-term environmental studies. However, the groups to be used must be carefully selected, considering the objectives and scope of the project. Quantifying the diversity condition of the compensation site concerning that found in a reference site seems to be a valid, repeatable, and evaluable procedure that allows establishing criteria on which to base compensatory measures.

Resumen Introducción: El establecimiento del Puesto Fronterizo Las Tablillas implica la segregación de 12.12 ha del Refugio Nacional de Vida Silvestre Corredor Fronterizo (RNVSCF), en el norte de Costa Rica. El sitio tiene una larga historia de uso de la tierra y su entorno natural está muy degradado. Este es un caso que se puede abordar desde el coste de oportunidad que se refiere al valor de la alternativa a la que se renuncia al tomar una decisión económica. Objetivo: En este artículo, usamos este precepto para evaluar la compensación por pérdidas en la estructura del hábitat y la biodiversidad si se interrumpiera la dinámica de sucesión dentro de un área silvestre protegida. Métodos: Para encontrar la ganancia neta en compensación requerida por dicha segregación, analizamos la diversidad y composición de la cubertura forestal cercana para pronosticar el ambiente que se perdería si se interrumpieran sus objetivos de conservación (costo de oportunidad). Compensar estas pérdidas requiere un ambiente equivalente, por lo que seleccionamos dos propiedades, entre 27 investigadas adyacentes al RNVSCF, que comparten cobertura forestal, están registradas legalmente y poseen atributos ambientales favorables para el diseño de reservas. Las dos propiedades seleccionadas y el sitio Las Tablillas fueron caracterizados a nivel de atributos geológicos e hidrológicos y de composición biológica de grupos indicadores. Resultados: Ambas propiedades son física y biológicamente favorables para el intercambio. La escogencia de cualquiera aumentaría el área del RNVSCF en más de 100 ha de un ambiente con mejor cobertura, más diversidad y mejor conexión con otras masas forestales que el observado en el sitio de segregación. Esto es una ventaja para el objetivo de conservación del refugio. Conclusión: En este caso, el coste de oportunidad favoreció la ganancia ambiental para la propuesta de compensación y podría ser utilizado para evaluar otras compensaciones que involucren ambientes sensibles o protegidos. Abstract Introduction: The establishment of the Las Tablillas Border Post implies the segregation of 12.12 ha within the National Wildlife Refuge Border Corridor (RNVSCF) in northern Costa Rica. The site has a long land use history, so its environment is highly degraded. This case can be studied from the opportunity cost, which refers to the amount of the alternative given up when making an economic decision. Objective: In this paper, we use this precept to assess the compensation for losses in habitat structure and biodiversity if succession dynamics within a protected wilderness area were interrupted. Methods: To find the net gain in compensation required by this segregation, we analyzed the diversity and composition of nearby forest cover to forecast the environment that would be lost if its conservation objectives were interrupted (opportunity cost). Compensating for these losses requires an equivalent environment, so we selected two properties, among the 27 investigated, that shared forest cover, are located adjacent to the RNVSCF, are registered, and possess other attributes favorable to the design of reserves. The two selected properties and the Las Tablillas site were characterized at the level of geological and hydrological attributes and the composition of indicator groups. Results: Both properties are physically and biologically favorable for the exchange. It would increase the area of the RNVSCF by more than 100 ha of an environment with better coverage, more diversity, and a better connection to other forest masses than the one observed in the segregation site, which is an advantage to the conservation objective of the refuge. Conclusion: In this case, the opportunity cost favored the environmental gain for the offset proposal and could be used to evaluate other compensation involving sensitive or protected environments.

PONDS ,CRONBACH'S alpha ,BIOTIC communities - Abstract
The latitudinal diversity gradient predicts that tropical regions should have higher alpha, beta, and gamma diversity than temperate areas. However, only a few studies have assessed the temporal variability of the different components of diversity across climatic regions. In this study, we compare, using a spatial and temporal approach, the diversity of multiple taxa inhabiting tropical and Mediterranean temporary ponds. We sampled the biological communities of each set of ponds on three occasions during the same hydrological year. Under a spatial framework, we analyzed, alpha, beta, and gamma diversities. With a temporal approach, we compared the coefficients of variation in alpha diversity for each local community, and temporal beta diversity. Differences between regions and sampling periods were tested using generalized linear mixed models. We found higher gamma and alpha diversity in the tropical ponds, as expected given the latitudinal differences between them. However, phytoplankton and microinvertebrates from the Mediterranean region, matched or even exceeded tropical alpha diversity on some occasions. Spatial beta diversity did not differ between regions, and it showed lower values at the middle or the end of the hydroperiod in bacteria, micro‐ and macroinvertebrates and amphibians. Thus, processes homogenizing and heterogenising pond metacommunities must be balanced in both studied regions. Temporal variation in alpha and beta diversity was similar for ponds in both regions, except for macroinvertebrates and amphibians, suggesting differential effects on community variation observable only in animals with longer life‐spans, at our temporal scale of analysis.

- Abstract
We report the first proteomics analyses of the venoms of two poorly studied snakes, the Manabi hognosed pitviper Porthidium arcosae endemic to the western coastal province of Manabí (Ecuador), and the Costa Rican hognosed pitviper P. volcanicum with distribution restricted to South Pacific Costa Rica and western Panamá. These venom proteomes share a conserved compositional pattern reported in four other congeneric species within the clade of South American Porthidium species, P. nasutum, P. lansbergii, P. ophryomegas, and P. porrasi. The paraspecific immunorecognition profile of antivenoms produced in Costa Rica (ICP polyvalent), Perú (Instituto Nacional de Salud) and Brazil (soro antibotrópico pentavalente, SAB, from Instituto Butantan) against the venom of P. arcosae was investigated through a third-generation antivenomics approach. The maximal venom-binding capacities of the investigated antivenoms were 97.1 mg, 21.8 mg, and 25.7 mg of P. arcosae venom proteins per gram of SAB, ICP, and INS-PERU antibody molecules, respectively, which translate into 28.4 mg, 13.1 mg, and 15.2 mg of total venom proteins bound per vial of SAB, ICP, and INS-PERU AV. The antivenomics results suggest that 21.8%, 7.8% and 6.1% of the SAB, ICP, and INS-PERU antibody molecules recognized P. arcosae venom toxins. The SAB antivenom neutralized P. arcosae venom's lethality in mice with an ED50 of 31.3 mgV/g SAB AV. This preclinical neutralization paraspecificity points to Brazilian SAB as a promising candidate for the treatment of envenomings by Ecuadorian P. arcosae. BIOLOGICAL SIGNIFICANCE: Assessing the preclinical efficacy profile of antivenoms against homologous and heterologous medically relevant snake venoms represents an important goal towards defining the biogeographic range of their clinical utility. This is particularly relevant in regions, such as Mesoamerica, where a small number of pharmaceutical companies produce antivenoms against the venoms of a small number of species of m

- Abstract
The latitudinal diversity gradient predicts that tropical regions should have higher alpha, beta, and gamma diversity than temperate areas. However, only a few studies have assessed the temporal variability of the different components of diversity across climatic regions. In this study, we compare, using a spatial and temporal approach, the diversity of multiple taxa inhabiting tropical and Mediterranean temporary ponds. We sampled the biological communities of each set of ponds on three occasions during the same hydrological year. Under a spatial framework, we analyzed, alpha, beta, and gamma diversities. With a temporal approach, we compared the coefficients of variation in alpha diversity for each local community, and temporal beta diversity. Differences between regions and sampling periods were tested using generalized linear mixed models. We found higher gamma and alpha diversity in the tropical ponds, as expected given the latitudinal differences between them. However, phytoplankton and microinvertebrates from the Mediterranean region, matched or even exceeded tropical alpha diversity on some occasions. Spatial beta diversity did not differ between regions, and it showed lower values at the middle or the end of the hydroperiod in bacteria, micro‐ and macroinvertebrates and amphibians. Thus, processes homogenizing and heterogenising pond metacommunities must be balanced in both studied regions. Temporal variation in alpha and beta diversity was similar for ponds in both regions, except for macroinvertebrates and amphibians, suggesting differential effects on community variation observable only in animals with longer life‐spans, at our temporal scale of analysis.

The metacommunity concept provides a theoretical framework that aims at explaining organism distributions by a combination of environmental filtering, dispersal, and drift. However, few works have attempted a multitaxon approach and even fewer have compared two distant biogeographical regions using the same methodology. We tested the expectation that temperate (mediterranean‐climate) pond metacommunities would be more influenced by environmental and spatial processes than tropical ones, because of stronger environmental gradients and a greater isolation of waterbodies. However, the pattern should be different among groups of organisms depending on their dispersal abilities. We surveyed 30 tropical and 32 mediterranean temporary ponds from Costa Rica and Spain, respectively, and obtained data on 49 environmental variables. We characterized the biological communities of bacteria and archaea (from the water column and the sediments), phytoplankton, zooplankton, benthic invertebrates, amphibians and birds, and estimated the relative role of space and environment on metacommunity organization for each group and region, by means of variation partitioning using generalized additive models. Purely environmental effects were important in both tropical and mediterranean ponds, but stronger in the latter, probably due to their larger limnological heterogeneity. Spatially correlated environment and pure spatial effects were greater in the tropics, related to higher climatic heterogeneity and dispersal processes (e.g., restriction, surplus) acting at different scales. The variability between taxonomic groups in the contribution of spatial and environmental factors to metacommunity variation was very wide, but higher in active, compared with passive, dispersers. Higher environmental effects were observed in mediterranean passive dispersers, and higher spatial effects in tropical passive dispersers. The unexplained variation was larger in the tropical setting, suggesting a higher role for stochastic processes, unmeasured environmental factors, or biotic interactions in the tropics, although this difference affected some actively dispersing groups (insects and birds) more than passive dispersers. These results, despite our limitations in comparing only two regions, provide support, for a wide variety of aquatic organisms, for the classic view of stronger abiotic niche constraints in temperate areas compared with the tropics. The heterogeneous response of taxonomic groups between regions also points to a stronger influence of regional context than organism adaptations on metacommunity organization. [ABSTRACT FROM AUTHOR]

- Abstract
Snakebite envenoming is a neglected tropical disease that may claim over 100,000 human lives annually worldwide. Snakebite occurs as the result of an interaction between a human and a snake that elicits either a defensive response from the snake or, more rarely, a feeding response as the result of mistaken identity. Snakebite envenoming is therefore a biological and, more specifically, an ecological problem. Snake venom itself is often described as a "cocktail", as it is a heterogenous mixture of molecules including the toxins (which are typically proteinaceous) responsible for the pathophysiological consequences of envenoming. The primary function of venom in snake ecology is pre-subjugation, with defensive deployment of the secretion typically considered a secondary function. The particular composition of any given venom cocktail is shaped by evolutionary forces that include phylogenetic constraints associated with the snake's lineage and adaptive responses to the snake's ecological context, including the taxa it preys upon and by which it is predated upon. In the present article, we describe how conceptual frameworks from ecology and evolutionary biology can enter into a mutually enlightening relationship with clinical toxinology by enabling the consideration of snakebite envenoming from an "ecological stance". We detail the insights that may emerge from such a perspective and highlight the ways in which the high-fidelity descriptive knowledge emerging from applications of -omics era technologies - "venomics" and "antivenomics" - can combine with evolutionary explanations to deliver a detailed understanding of this multifactorial health crisis.

- Abstract
The Duvernoy's gland secretory proteome of the false coral snake Rhinobothryum bovallii (Costa Rica), unveiled applying bottom-up venomics, comprises a handful of toxins belonging to only three protein families, three-finger toxin (3FTx), cysteine-rich secretory protein (CRISP), and snake venom metalloprotease (PIII-SVMP). Except for small differences in the relative abundance of the PIII-SVMPs, which may be due to individual variability, no evidence of geographic variability or ontogenetic changes was found among the venom proteomes of the juvenile and adult R. bovallii snakes sampled. Major monomeric (86.5%mol) and minor dimeric (2.8%mol) 3FTxs dominate the toxin arsenal of the Costa Rican false coral snake. The remaining 10.7% of the venom proteome comprises CRISP (8.2%) and PIII-SVMP (2.4%) molecules. In vivo lethality assays showed that R. bovallii produces venom that is non-toxic towards mammalian prey, and which exerts a different toxic effect on domestic chicken chicks and baby green iguana. Toxicovenomic analysis of R. bovallii venom in the iguana model identified two 3FTx RP-HPLC fractions that faithfully mimicked the irreversible immobilizing effect of the whole venom. BIOLOGICAL SIGNIFICANCE: With more than 2200 species in family Colubridae (sensu lato), rear-fanged snakes comprise approximately two-thirds of the extant species of advanced snakes. Snakebites from venomous snakes that are of medical concern are predominantly from front-fanged snakes of families Viperidae and Elapidae. On the other hand, rear-fanged snakes have been conventionally considered non-venomous, and thus their venoms have remained a largely untapped area of venomics. However, increasing documentation of life-threadening, even fatal, envenomings from rear-fanged snakes has sparked interest in their venoms. Appying bottom-up venomics we have revealed that the Duvernoy's gland secretory proteome of R. bovallii comprises a handful of toxins belonging to only three protein families, w

El papel de la dogmática en la concepción del precedente jurisprudencial debe ser de inclusión y transdisciplinariedad. Atrás quedó la idea clásica de que la dogmática jurídica se limitaba a la descripción avalorada de los presupuestos normativos que resultaban útiles para la resolución de casos y, en su lugar, se ha adoptado una “nueva dogmática” que pretende incorporar en la decisión judicial los valores consagrados en el ordenamiento jurídico y social. El presente trabajo materializa la “nueva dogmática” en uno de los temas más discutidos en el derecho colombiano: el precedente jurisprudencial. Para tal fin, apelando a la tópica jurídica, se analizan las teorías a favor y en contra de la vinculatoriedad del precedente jurisprudencial en el derecho colombiano durante los últimos veinte cuatro años, luego de lo cual, se concluye que ambas corrientes son profundamente avaloradas y formalistas, por lo que se recomienda la inclusión de la democracia deliberativa en su estudio. Lo anterior en aras de garantizar que el análisis de la ciencia jurídica en general, y del precedente jurisprudencial en particular, no se limite al campo de la validez del derecho, sino que además incluya el aspecto político de la legitimidad. (texto tomado de la fuente) The role of dogmatic in the conception of the judicial precedent should be inclusive and transdisciplinary. Before, people had the idea about the dogmatic like something that confine itself to the description of rules without moral content that provide an answer for every case. Instead, we have adopted a “new dogmatic” in order to incorporate the values of the legal and social order in judicial decisions. This paper embodies the “new dogmatic” in one of the most discussed topics in colombian law: the judicial precedent. For that purpose, appealing to topic, theories in favor or against the binding nature of judicial precedent in colombian law are analyzed over the last twenty four years, whereupon, it is concluded that both are deeply formalist, so the inclusion of deliberative democracy in those studies is recommended. This in order to ensure that the analysis of legal science in general, and judicial precedent in particular way, not only focuses in the legal validity, but also includes the political dimension of legitimacy.

- Abstract
The maintenance of reptiles and amphibians in captivity has greatly developed worldwide, becoming the basis of many conservation, education, and research programs. In Costa Rica, this trend is evident in the proliferation of centers that maintain herpetofauna in the last two decades. Despite this development, there is no information available on the centers existing in Costa Rica, and the way they operate, or the potential impacts they could have on the species kept remain unknown. In this study, we describe the facilities currently operating in the country, through a series of interviews to their owners or technical staff, and in situ observations. A total of 33 centers were found, which keep up to 144 species of reptiles and amphibians. This large number of facilities resulted from the development of the tourism industry in the country: most of them are intended to display animals, although some reported educational purposes. Most interviewed staff claims that generation of knowledge is one of the main objectives of their center. However, only four of them showed clear evidence of research programs. A significant percentage of centers get their animals directly from the natural environment, a practice that might have an impact on species with reduced populations in the wild. This seems to be the case of the Bushmaster Lachesis stenophrys, found in 66% of the centers, despite being a species that is nowadays threatened in the country. The existence of these facilities demonstrates the interest Costa Rica society has on wildlife, and it is an interesting mosaic of experiences, opportunities, and challenges for the environmental scene of the country., La tenencia de herpetofauna en cautiverio es una actividad que ha experimentado un enorme desarrollo en distintas partes del mundo, constituyéndose en la base de muchos programas de conservación, educación, e investigación. En Costa Rica, esta tendencia se evidencia en la proliferación de centros que mantienen reptiles y anfibios en las últimas dos décadas. Pese a este desarrollo, no hay disponible información centralizada sobre los herpetarios a nivel del país, por lo que se desconoce la forma como operan o los potenciales impactos que pudieran tener en la conservación de las especies mantenidas en ellos. En este trabajo se describen los centros que actualmente funcionan en el país, para lo cual se realizaron entrevistas a sus propietarios o regentes y visitas de conformación. Un total de 33 centros, que en conjunto albergan 144 especies, fueron encontrados. Este número de herpetarios resulta del desarrollo de la industria turística: la mayoría de ellos tienen como finalidad la exhibición de animales, aunque también algunos reportan fines educativos. Solo en cuatro centros se encontró clara evidencia de programas de investigación, pese a que la mayoría de herpetarios indicó la generación de conocimiento como uno de sus principales objetivos. Una proporción importante de establecimientos obtiene sus animales del medio, lo que supone un impacto en aquellas especies con poblaciones reducidas. Tal parece ser el caso de la matabuey Lachesis stenophrys, que se encontró en 66% de los centros, pese a ser una especie con poblaciones amenazadas en el país actualmente. La existencia de estos establecimientos demuestra el interés de nuestra sociedad por la tenencia de vida silvestre, y supone un interesante mosaico de experiencias, posibilidades y retos para la escena ambiental del país.

This involves that the traditional scope provided by the jurist respect freedom of speech should be reformulated, as, among another important aspects, the subjects of protection had changed, the communication canals are multiples and the public which access each contents of guarantee is very diverse and complex. Similarly, all forms of affectation and legitimate restriction of liberty must be redefined. This paper will try to answer the following question: it is the criminal law the appropriate mechanism for regulate the freedom of speech at the Internet?, Las redes sociales revolucionaron el derecho a la libertad de expresión. Al abrir las puertas a un nuevo modelo comunicativo de corte multidireccional, horizontal, descentralizado, interactivo y con vocación democratizadora normalizaron la posibilidad de difundir ideas y opiniones propias, así como la posibilidad de conocer las de los demás. Ello implica que el alcance tradicional que han dado los juristas a la libertad de expresión deba ser reformulado, pues, entre otras causas, los sujetos de protección han variado, los canales de difusión son múltiples y el público que accede a los contenidos es muy variado. Así mismo, las formas de restricción y afectación legítima a la garantía deben reformularse. Este artículo tratará de responder al siguiente interrogante: ¿Es el derecho penal un mecanismo adecuado para regular el ejercicio del derecho a la libertad de expresión en Internet?
