Deeper insight into the molecular pathways that orchestrate skeletal myogenesis should enhance our understanding of, and ability to treat, human skeletal muscle disease. It is now widely appreciated that nutrients, such as molecular oxygen (O2), modulate skeletal muscle formation. During early stages of development and regeneration, skeletal muscle progenitors reside in low O2 environments before local blood vessels and differentiated muscle form. Moreover, low O2 availability (hypoxia) impedes progenitor-dependent myogenesis in vitro through multiple mechanisms, including activation of hypoxia inducible factor 1α (HIF1α). However, whether HIF1α regulates skeletal myogenesis in vivo is not known. Here, we explored the role of HIF1α during murine skeletal muscle development and regeneration. Our results demonstrate that HIF1α is dispensable during embryonic and fetal myogenesis. However, HIF1α negatively regulates adult muscle regeneration after ischemic injury, implying that it coordinates adult myogenesis with nutrient availability in vivo. Analyses of Hif1a mutant muscle and Hif1a-depleted muscle progenitors further suggest that HIF1α represses myogenesis through inhibition of canonical Wnt signaling. Our data provide the first evidence that HIF1α regulates skeletal myogenesis in vivo and establish a novel link between HIF and Wnt signaling in this context.
Early Twentieth-Century Terms for New Verse Forms (‘free verse’ and others) in Japanese and Arabic
Authors: Mehl Scott
Published: July 2015

In the first half of the twentieth century, when Japanese and Arabic poets began writing free-verse poetry, many terms were proposed as labels for the new form. In addition to the calques on “free verse,” neologisms were created to name the new poetry. What is striking is that, in these two quite different literary spheres, a number of the proposed neologisms were the same: for example, in both Japanese and Arabic the terms prose poetry, modern poetry, and colloquial poetry were proposed (among others) as alternatives to the label free poetry. This essay provides an annotated list of the neologisms in Japanese and Arabic, with a list of English terms for comparison; and by referring to the contemporary Japanese and Arabic criticism on the topic of poetic innovation, this essay attempts to explain the similarity between the Japanese and Arabic neologisms. In short, the Japanese and Arabophone arguments in favour of adapting the free-verse form were based on similar premises regarding modernity, freedom, and a vision of literary history that was rooted in an evolutionary theory of genre development.
Teaching Tomorrow’s Leaders by Discussing Today’s Media
Authors: Morin Lee , Turesky Elizabeth Fisher , Robinson Betty
Published: July 2015

Can parents identify leadership lessons in children’s media and use them to teach their children leadership? Thirty participants were asked to answer questions about leadership in children’s media before and after watching clips of a popular G-rated children’s movie. The results from the questionnaire indicated that parents do recognize leadership behaviors in children’s media and do feel that their children are learning from the media. As a result of this learning environment, children become more aware of leadership. Further, sixty-seven percent of the parents claimed to reinforce the positive messages in the media, and seventy percent claimed to teach their children about leadership. In two participant groups, results varied by gender and education level. The study recommends ways for parents and media producers to emphasize leadership messages so as to foster leadership development in children
The Hidden “Who” in Leadership Education: Conceptualizing Leadership Educator Professional Identity Development
Authors: Seemiller Corey , Priest Kerry L.
Published: July 2015

A great deal of literature exists for leadership educators related to programs design, delivery, and student learning. However, little is known about leadership educators, who have largely been left out of contemporary leadership education research. We looked to teaching and teacher education literature to derive a model for leadership educator professional identity development. The four spaces of identity development are exploration, experimentation, validation, and confirmation. We propose that an individual can move forward and backwards through the model as a result of both ongoing influences and positive or negative critical incidents. We discuss implications for professional development and future research.
Ebola revisited: lessons in managing global epidemics
Authors: Boulton Jacqueline
Published: July 2015

The latest statistics for the number of new cases of Ebola virus disease (EVD) in West Africa point to the near containment of the virus. While the current threat will not be deemed over until 42 days after the last case to be diagnosed has twice tested negative, there is now a shift in focus from an emphasis on containment to that of policy review and capacity building in light of lessons learned. This article primarily focuses on Sierra Leone. It revisits the issues surrounding the epidemic, seeking to summarise both the negative and positive aspects of the response at local and global levels, as well as highlights fresh perspectives from healthcare workers in the field for the management of similar epidemics.

Indian ICU nurses' perceptions of and attitudes towards organ donation
Authors: Vijayalakshmi Poreddi , Nagarajaiah  , Ramachandra  , Math Suresh Bada
Published: July 2015

Nurses play a significant role in identifying and securing potential organ donors in the clinical environment. Research among Indian nurses related to organ donation is sparse. The present study aimed to investigate nurses' attitudes towards organ donation. A cross-sectional descriptive survey was carried out among nurses (n=184) at a tertiary care centre. Data were collected through self-report questionnaire. A majority (81%) of the respondents were ‘willing to sign the card’ for organ donation; however, only 3.8% (n=7) of them actually ‘signed the organ donation card’. There were significant associations found between intentions to sign the organ donation card and gender (x2=5.852; p<0.054), religion (x2=40.175; p<0.000), and experience caring for brain-dead patients (x2=22.790; p<0.001). The researchers strongly suggest continuing education for nurses to enhance skills and knowledge, as well as sensitivity to cultural, ethical, social, and religious issues, and advocacy in the area of organ donation. Furthermore, nurse administrators must take the initiative to develop guidelines clarifying the role of nurses in the organ donation and transplantation process to promote organ donation and improve rates.
How critical care nurses' roles and education affect organ donation
Authors: Jawoniyi Oluwafunmilayo Ololade , Gormley Kevin
Published: July 2015

Organ and tissue dysfunction and failure cause high mortality rates around the world. Tissue and organs transplantation is an established, cost-effective, life-saving treatment for patients with organ failure. However, there is a large gap between the need for and the supply of donor organs. Acute and critical care nurses have a central role in the organ donation process, from identifying and assessing potential donors and supporting their families to involvement in logistics. Nurses with an in-depth knowledge of donation understand its clinical and technical aspects as well as the moral and legal considerations. Nurses have a major role to play in tackling organ and tissue shortages. Such a role cannot be adequately performed if nurses are not fully educated about donation and transplant. Such education could be incorporated into mandatory training and completed by all nurses.

The effect of government expenditures on Indonesia economic growth
Authors: Nurlina Nurlina
Published: July 2015

The debate on the effect of government expenditure on economic growth has still happened in relation to classical groups and Keynesians view. The aim of this study confirms the relationship, with the application of the case in Indonesia. Gov-ernment expenditures are aggregated, while economic growth is measured by gross domestic product. With time series design, the secondary data used covers the period of 2004 to 2013. At first, the data were analyzed descriptive-graphics, while the hypothesis testing using t-test. The results obtained indicate that government spending has a positive and significant influence to economic growth. Thus, spend-ing and investment forms by government as a form of fiscal policy must be done with great caution in order to avoid misallocation or inequality in the distribution of inter-sector development, given the importance of its role as a pending national economic growth.
Good governance and fiscal capacity in regional expansion: A holistic analysis of qualitative perspective
Authors: Syarifuddin Syarifuddin , Damayanti Ratna Ayu
Published: July 2015

This study aims to analyze the problem in a holistic manner of good governance and fiscal capacities in territorial splits. This study is qualitative in which the researchers made a description of the phenomenon, as well as researching the words, a detailed report of the views of informants, and conducting analysis based on the natural set-ting. The study found that the territorial splits undertaken in the Province of West Sulawesi provides the government an opportunity to integrate the three pillars of good governance. These three pillars work together in planning and implementation of regional policy. The study concludes that the territorial splits in the Province of West Sulawesi are a policy that is responsible and important from the aspect of good gover-nance. On the other hand, the study shows that the territorial splits have led to weak local fiscal capacity. This is due to the territorial splits in the area of West Sulawesi province that has not been able to encourage the growth of local fiscal capacity, which in fact it is expected to encourage the degree of fiscal autonomy of the regions.

The fact is that natural rubber has a strategic role as it is one of the commodities industry tropical crops. In addition, it also has important and strategic role in sup-porting the national economy, primarily as a source of livelihood of millions of rub-ber farmers in rural areas. This study analyzed the potential of using family labor in rubber smallholding sector in Banyuasin Regency, South Sumatra Province, Indo-nesia. The total sample used for the study was 280 respondents of households. Data was analyzed using multiple regression analyses. The multiple regression analysis used to identify the determinants of labor force participation decision regarding work in the rubber smallholding in the study area such as rubber production (kg per year per hectare), number of family workers, age of family head, location of dwelling, education of family head, and average years of schooling of family workers. Based on the analysis, only two factors affected significantly family labor force participation outside their smallholdings, namely number of family labor and education of family head.

Published: July 2015

Todos los manuales reconocen la necesidad de integrar el elemento cultural en el aula de ELE, pero hay que analizar de qué manera se ve reflejado. En muchas ocasiones los objetivos relacionados con la reflexión y la diversidad lingüística y cultural son insuficientemente presentados y contextualizados. Este artículo se centra en el análisis de algunos textos e imágenes de un manual de ELE, por la discusión y polémica que provocaron algunas de sus imágenes y determinados contenidos culturales al llevarlos al aula con algunos de nuestros alumnos universitarios jamaicanos. Algunos manuales pretenden ser globales e interculturales para evitar el choque con estudiantes de culturas distintas. Nuestra práctica docente en un contexto cultural diferente prueba que sí se produjeron algunos “choques” con la cultura de los estudiantes.

Owing to the worldwide efforts, the development of extreme ultraviolet (EUV) lithography has significantly progressed during the past decade. The resolution of chemically amplified resists has reached sub-16-nm region. From the viewpoint of the extendibility of EUV lithography, the development of resist materials capable of resolving sub-10-nm is an urgent task. In this review, the resist material options for EUV lithography are discussed on the basis of the EUV sensitization mechanisms after reviewing the problems for the sub-10-nm fabrication.
DNA barcoding reveals high diversity in the Gelidiales of the Brazilian southeast coast
Authors: Iha Cíntia , Milstein Daniela , Guimarães Silvia Maria P.B. , Freshwater D. Wilson , Oliveira Mariana Cabral
Published: July 2015

Morphological identification of species in the order Gelidiales can be difficult and controversial because of phenotypic plasticity, the low numbers of reproductive specimens and poorly defined taxonomic boundaries. A DNA barcoding survey of Brazilian specimens of Gelidiales, employing neighbor-joining and Automatic Barcode Gap Discovery analyses, indicated the presence of 23 statistically robust primary species hypotheses (PSH). In addition to the cytochrome oxidase I gene (COI-5P), the chloroplast universal plastid amplicon (UPA) marker was also sequenced and submitted to the same analyses. Representatives of each COI-5P/UPA PSH were selected for rbcL sequence analysis to further corroborate the occurrence of 23 species and to infer their phylogenetic relationships. These analyses confirmed the identity of six species previously cited for Brazil: Gelidiella acerosa, G. ligulata, Gelidium crinale, G. floridanum, Pterocladiella bartlettii and P. capillacea. Three new reports for Brazil were also detected: Gelidium microdonticum, Pterocladiella beachiae and P. australafricanensis. Fourteen species remain unidentified and require detailed morphological evaluation.

When less is more for the struggling clinical reasoner
Authors: Connor Denise M. , Dhaliwal Gurpreet
Published: July 2015

Busy clinician-educators are often tasked with remediating medical students who have deficits in clinical reasoning. In this essay, we share our early experience with providing less feedback and more practice to these trainees. We suggest that front line teachers can streamline their feedback to struggling reasoners by focusing solely on the problem representation and prioritized differential diagnosis of the main problem in their oral presentations and then engaging in repeated loops of feedback until the student achieves competency in real time. By receiving feedback targeted to the assessment alone and employing deliberate practice, struggling students have the opportunity to make concrete improvement during short-term clinical assignments. This remediation approach is feasible for busy clinician-educators and warrants formal study.

Erratum to: Crassus’ Command in the War against Spartacus (73–71 BCE): His Official Position, Forces and Political Spoils
Authors: Vervaet Frederik Juliaan
Published: July 2015

Late in 72 BCE, Spartacus’ stunning series of victories over the consuls L. Gellius Publicola and Cn. Cornelius Lentulus Clodianus and then the proconsul C. Cassius Longinus (cos. 73) triggered a dearth of candidates for the consular and praetorian elections for 71. This deadlock was broken only when M. Licinius Crassus announced that he would run for praetor, declaring he was prepared to accept the command against Spartacus. Immediately following his election, Crassus began preparing, probably receiving a grant of delegatedpraetorium imperiumto bridge the interval between election and assumption of office. Having raised no less than six legions, personally advancing the funds required, he also took command of the two consular legions in the field. By means of this enormous army as well as his relentless efforts and strict discipline, he managed to put an end to this protracted and inglorious war in the span of six months. At some point in the summer or early autumn of 71, the equestrian proconsul Cn. Pompeius Magnus, back from Spain, decided he would settle for nothing less than another public triumph and the consulship itself. In order to secure these top prizes, he brazenly refused to disband his army, instead using it as leverage, just as he had already done in 81 and 77.

Crassus, for his part, felt he could not fall behind, and entered into an unlikely if formidable alliance with his political rival. As both men ran on a strongpopullarisplatform, the Senate now found itself between hammer and anvil. Consequently, the Conscript Fathers had little choice but to grant Pompeius as well as Crassus the required dispensations from the Cornelian Law. Although they subsequently honoured their popular commitments as consuls, that neither Pompeius nor Crassus chose to disband their armies until sometime late in their tenure suggests that their entente was anything but cordial. Interestingly, it was Crassus who defused this dangerous stalemate by making the decisive first move towards formal reconciliation, albeit in the face of massive public pressure. Paradoxically, the defining features of Sulla’s new constitutional arrangement were buried by two of his foremost associates as they first trampled two critical Cornelian laws in order to seize a joint consulship and next passed legislation restoring the powers of the tribunes of theplebsand altering the balance of power in the court juries.
Quod nunc Rubrum ad mare patescit: the mare Rubrum as a frontier of the Roman Empire
Authors: Schneider Pierre
Published: July 2015

This article deals with an excerpt from Tacitus’ Annals which has often been commented on. The famous account of Germanicus’ Egyptian tour contains a puzzling remark about Syene (claustra olim Romani imperii quod nunc Rubrum ad mare patescit): the adverb nunc refers in an allusive way to a recent expansion of the Roman Empire. Several scholars have rightly pointed to the Nabataean kingdom, a conclusion which seems to be the best one. The mare Rubrum therefore was not seen by Tacitus and his public as a limit of Roman Egypt. In contrast, from Tacitus’ point of view, it is the southern part of Arabia, bordered by the mare Rubrum, that became the new frontier of the Roman Empire after the annexation of the Nabataean kingdom. How this event was considered as a major expansion of the imperium Romanum is examined in the last section of the present paper.
Cassius Dio, Caracalla, and the Senate
Authors: Scott Andrew G.
Published: July 2015

Recently, efforts have been made to characterize Cassius Dio’s history of the reign of Caracalla as reflective of the experiences of a marginalized senator, rather than of the senate as a whole. A re-evaluation of Dio’s account suggests that Dio’s version of events should remain the most valuable literary source for this period. Dio maintained a consistent view of the principate throughout his contemporary history, and his depiction of Caracalla as hostile toward the senate is supported by other sources. Finally, a survey of Dio’s political career shows that he evaluated each emperor in his contemporary history through the example of the ideal emperor, Marcus Aurelius, not according to the favor (or lack thereof) he experienced under each ruler.

Evolución de la femme fatale en Cautivo del deseo: de la tentación y la humillación a la locura y la muerte
Authors: Visa Barbosa Mariona
Published: July 2015

En este artículo se analiza la evolución del personaje femenino en la película Cautivo del deseo (Of human boundage, John Cromwell, 1934), interpretada por Bette Davis y Leslie Howard. La mujer protagonista de la historia encarna el papel de una típica femme fatale, que pasa por diferentes estadios a lo largo de la película, los cuales son analizados en detalle en este artículo. Aparece en un principio de forma discreta y positiva para ir poco a poco transformándose en una mujer fría que humilla al protagonista masculino constantemente. Finalmente, como en otros finales de películas del cine negro anterior a la II Guerra Mundial, su personaje es castigado por los guionistas, refugiándola en la locura para llevarla finalmente a la muerte. Por el contrario, el personaje masculino encarna el arquetipo de un anti-héroe que será transformado positivamente al final de la historia. En este texto se estudia la evolución de los dos protagonistas de la película y en concreto la forma en que se representa la mujer como femme fatale en las diferentes fases de la historia,. El análisis parte de una metodología narrativa y aplica los postulados de las estructuras antropológicas del imaginario introducidas por Gilbert Durand en los años 60.

Published: July 2015

Este trabajo trata de desvelar la doble relación que existe entre las personas mayores y la televisión. Se da por supuesto que son unos grandes consumidores de la misma, puesto que la televisión juega un papel importante en su tiempo libre, pero está menos analizado cómo y cuánto aparece la tercera edad como objeto de una noticia. Así, nos hemos centrado en buscar los programas informativos de una televisión concreta, en este caso la de Andalucía, durante una temporada completa para fijarnos cuántas veces aparecen y cuál ha sido el contenido de los temas en que intervienen. Así hemos visto que son poco tratados, menos de lo que cuantitativamente significa este grupo de edad en la población, y hemos detallado los temas en que son más recogidos. Vemos que en los programas diarios se centran más en su relación con asuntos derivados de la política, mientras que en los programas no diarios, son más utilizados como sujetos activos
The impact of sperm-expressed transcription factors on fate-mapping models
Authors: Yuan Xin , Du Jianlin , Qin Qin , Li Xiaoqun , Deng Songbai , Chen Yunqing , Zhang Ling , She Qiang
Published: July 2015

Genetic lineage tracing has been used extensively in developmental biology. Many transcription factors expressed in sperm may induce Cre-mediated loxP recombination during early zygote development. In this study, we investigated the effect of sperm-expressed Cre on cell type-specific Cre-mediated loxP recombination in fate-mapping models of Tbx18+ progenitor cells. We found the recombination frequency in a reverse mating (RM) lineage was inconsistent with a normal Mendelian distribution. However, the recombination frequency in a positive mating (PM) lineage agreed with a Mendelian distribution. In the PM lineage, LacZ and EYFP were expressed in specific locations, such as the limb buds, heart, and hair follicles. Therefore, the reporter genes accurately and reliably traced cell differentiation in the PM lineage. In contrast, EYFP and LacZ were expressed throughout the embryo in the RM lineage. Thus, the reporter genes did not trace cell differentiation specifically in the RM lineage. Furthermore, Tbx18 mRNA and protein were expressed in the testicles of male mice, but almost no Tbx18 expression was detected in the ovaries of female mice. Similarly, reporter genes and Tbx18 were coexpressed in the seminiferous tubules and sperm cells of testicles. These results revealed that Cre-loxP-mediated pre-recombination in zygotes is due to Tbx18 expressed in testicle sperm cells when Cre is transmitted paternally. Our results indicate that Cre-mediated specific recombination in fate-mapping models of sperm-expressed genes may be influenced by the paternal origin of Cre. Therefore, a careful experimental design is critical when using the Cre-loxP system to trace spatial, temporal or tissue-specific fates.

Inflorescences of the tribe Triticeae, which includes wheat (Triticum sp. L.) and barley (Hordeum vulgare L.) are characterized by sessile spikelets directly borne on the main axis, thus forming a branchless spike. ‘Compositum-Barley’ and tetraploid ‘Miracle-Wheat’ (T. turgidum convar. compositum (L.f.) Filat.) display noncanonical spike-branching in which spikelets are replaced by lateral branch-like structures resembling small-sized secondary spikes. As a result of this branch formation ‘Miracle-Wheat’ produces significantly more grains per spike, leading to higher spike yield. In this study, we first isolated the gene underlying spike-branching in ‘Compositum-Barley,’ i.e., compositum 2 (com2). Moreover, we found that COM2 is orthologous to the branched headt (bht) locus regulating spike branching in tetraploid ‘Miracle-Wheat.’ Both genes possess orthologs with similar functions in maize BRANCHED SILKLESS 1 (BD1) and rice FRIZZY PANICLE/BRANCHED FLORETLESS 1 (FZP/BFL1) encoding AP2/ERF transcription factors. Sequence analysis of the bht locus in a collection of mutant and wild-type tetraploid wheat accessions revealed that a single amino acid substitution in the DNA-binding domain gave rise to the domestication of ‘Miracle-Wheat.’ mRNA in situ hybridization, microarray experiments, and independent qRT-PCR validation analyses revealed that the branch repression pathway in barley is governed through the spike architecture gene Six-rowed spike 4 regulating COM2 expression, while HvIDS1 (barley ortholog of maize INDETERMINATE SPIKELET 1) is a putative downstream target of COM2. These findings presented here provide new insights into the genetic basis of spike architecture in Triticeae, and have disclosed new targets for genetic manipulations aiming at boosting wheat’s yield potential.

The simplicity and ease of access of its website, has allowed YouTube to be embraced by the whole world and establish itself as the most prominent form of video sharing on earth. YouTube has become a widely used medium for individuals, corporations, and academic institutions alike. In the current work a W-index has been developed and applied to many academic institutions to evaluate the efficacy of the respective YouTube channel(s). This index was the creative product of the senior author who was inspired by the H-index developed by J.E. Hirsch (2005) to evaluate the productivity and impact of a researcher. The W-index will be used to evaluate the quantity and quality of a University’s channel that is different from the traditional staples that define popularity and video effectiveness on YouTube, such as total views. The methodology used would be to see that if this W-index would correlate well to existing indices used for the evaluation of universities. Eventually, the W-index could serve as an indicator of whether or not a university needs to invest time or money into the development of better videos or more videos for their YouTube channel to maximize its impact on the academic community. A correlation between W-Index and three well-established and well-defined cybermetric rankings; US Rank, Impact Rank, and Excellence Rank, is established and used as the basis for the Windex’s usefulness. The establishment of such a correlation indicates that the W-Index can also be used to evaluate the communication efficacy of individuals, despite the lack of any robust ranking system for individuals. The W-Index serves as a good indicator, based on consistent correlation coefficients among ranking systems analyzed, of a university or individual’s success and communication efficacy. Rankings are useful as single numbers that contribute to decision making, simply because of their simplicity.

Flexible electrodes are widely applied to many fields such as sensor, flexible printed circuit board, photovoltaic cell, cell phone, digital camera, and liquid crystal display and so on. Aim at the connecting problem between flexible electrodes and external wires; the detachable clamping connection was firstly brought forward to solve the aim problem under normal temperature. And on the basis of such idea, the corresponding clamper was designed and fabricated further by mechanical procedures. Then verifying and comparing experiments were done and observed. Experiment results illustrate that the detachable clamping connection is correct and effective and that such connection could solve the aiming problem without high temperature welding procedure. And furthermore it’s also known that clamper doesn’t change the main characteristics of signal transmission. The detachable clamping connection is very useful and effective for the connection between flexible thin film conductor and common wires when they can not be directly welded together under high temperature.

Published: July 2015

Con la finalidad de evaluar la asociación de índices de crecimiento en estadios tempranos de peces marinos, se estimó la tasa de crecimiento somático y las condiciones fisiológicas de Eucinostomus argenteus en dos zonas del nor-oriente venezolano: Bahía de Mochima y Golfo de Cariaco. La edad y el crecimiento fueron estimados basados en análisis de otolitos sagitta. Las condiciones fisiológicas fueron evaluadas por medio de las concentraciones de proteínas y la relación ARN/ADN, empleando técnicas espectofotométricas y fluorométricas sobre tejido muscular. Las relaciones entre tallas con la edad y el diámetro de los otolitos resultaron positivas, significativas y ajustadas a un modelo de regresión lineal. Los valores de la tasa de crecimiento reciente oscilaron entre 0.178 y 0.418mm día-1, la tasa de crecimiento retrocalculado varió entre 0.295 y 0.393mm día-1, y la tasa ARN/ADN osciló entre 1.65 y 6.97. No se registraron diferencias entre las zonas de estudio, sin embargo se reportaron diferencias entre localidades. A pesar de no encontrarse correlación entre la tasa de crecimiento y la relación ARN/ADN, los valores reportados sugieren crecimiento positivo de los individuos silvestres en las localidades evaluadas. No obstante, ciertas localidades mostraron valores que indican pobres condiciones nutricionales, pudiendo afectarse a futuro otras tasas vitales.

En este estudio se describe la condición de las comunidades bentónicas e ictícolas en cuatro arrecifes que fueron monitorizados durante 2003 y 2004 en Venezuela: Dos Mosquises Sur y Madrizquí en el Parque Nacional Archpiélago Los Roques y Caimán y Cayo Norte en el Parque Nacional Morrocoy. Para ello, empleamos los protocolos de CARICOMP y AGRRA para describir la comunidad bentónica e ictícola, respectivamente. La cobertura de los cinco principales grupos bentónicos difirió entre arrecifes (ANOVA anidado, p < 0.05) más no entre parques. A pesar de pertenecer a diferentes parques la estructura de la comunidad bentónica entre Dos Mosquises Sur y Cayo Norte mostró un índice de similitud (Bray-Curtis) de 76%, mientras que Caiman difirió entre 57 y 68% con respecto a todos los arrecifes. Como se esperaba, la cobertura coralina, algas esponjas y octocorales no cambió entre 2003 y 2004. De forma similar, la comunidad de peces tampoco cambió en el tiempo y estuvo dominada por especies de herbívoros (Pomacentridae, Scaridae and Labridae). Sin embargo, en Los Roques los carnívoros de importancia comercial (e.g. lutjanidos y serranidos) fueron más abundantes que en Morrocoy. Aunque se esperaba encontrar diferencias en la comunidad bentónica e ictícola de Los Roques y Morrocoy, solo la de peces reflejó las diferencias, encontrándose en mejor estado de salud en Los Roques, mientras que CNOR, localizado en Morrocoy, presentó una cobertura similar o ligeramente mayor que los arrecifes localizados en Los Roques. Por lo tanto, los resultados de este estudio muestran que los arrecifes oceánicos no necesariamente se encuentran en mejor estado que los costeros. La inclusión de 3 nuevos sitios y la reincorporación de Caimán ha expandido y mejorado las capacidades de monitoreo de Venezuela y representa el primer paso hacia la creación de un sistema de monitoreo de arrecifes en el país.

En respuesta al proceso de deterioro de los arrecifes coralinos colombianos en las últimas tres décadas, y con el propósito de establecer un sistema de vigilancia para el manejo apropiado de estos valiosos ecosistemas, el Instituto de Investigaciones Marinas y Costeras (INVEMAR) desde 1998 ha impulsando y puesto en marcha el Sistema Nacional de Monitoreo de Arrecies Coralinos en Colombia (SIMAC), con el apoyo de varias instituciones colombianas. El SIMAC ha operado sin interrupción por más de ocho años, periodo durante el cual se han establecido 63 parcelas permanentes de observación y 267 transectos fijos de evaluación, en diez de las principales áreas geográficas con arrecifes de Colombia (siete en le Caribe y tres en el Pacífico). Los procedimientos metodológicos del SIMAC se hallan descritos detalladamente en el manual de métodos e incluyen: cobertura del bentos arrecifal, densidad de gorgonáceos, prevalencia de enfermedades coralinas, abundancia de invertebrados móviles selectos, riqueza ictiológica y densidad de familias selectas de peces, así como algunas variables indicadoras de la calidad del agua. Los resultados del SIMAC han sido circulados a través de reportes resumen para las agencias del gobierno y público en general y han apoyado iniciativas regionales y globales de monitoreo (i.e. CARICOMP, GCRMN, ReefBase). En este artículo se describe el desarrollo de este sistema y en otros artículos dentro de este número especial se presentan los principales resultados del monitoreo.

Un estudio sobre poblaciones bentónicas y de peces fue realizado en cinco localidades en la zona costera en el suroeste de Grenada entre 2008 y 2010. Dos sitios se ubicaron en una Área Marina Portegida (AMP) recientemente creada. Para determinar la cobertura se utilizaron foto-cuadrantes (FQ) y transectos de intersección de puntos (TIP). Las algas fueron el principal componente del bentos, aumentando significativamente de 45,9% en 2008 a 52,7% en 2010 (TIP). Las algas también fueron predominantes (61,9%-59,3) en los FQ, aunque las diferencias anuales no fueron significativas. La cobertura de corales pétreos tenía un ámbito de 16,5% a 15,4% (TIP) y de 11,4% a 12,0% (FQ), sin diferencias significativas entre años. Los corales ramificados e incrustantes fueron más frecuentes que los corales masivos. En los tres años no hubo diferencias significativas entre las AMPs y las áreas no protegidas. La abundancia relativa de peces a lo largo de un transecto de 30x2m no varió significativamente entre los años, sin embargo, la densidad de peces decreció significativamente a través de los años, para los grupos principales. Chromis spp. predominó con 65,2% en 2008 y 49,8% en 2012, seguido por damiselas territoriales, 11,1% y 15,5%, y los lábridos aumentaron de 7,3% a 15,5%. Tanto la coberura del sustrato como los datos de peces indican una comunidad estable pero degradada. Sondeos anuales están planeados para el futuro. Los datos existentes y futuros de este proyecto serán muy útiles para determinar la eficacia de la gestión de las AMPs y el estado de salud de los sistemas arrecifales de Grenada.
