Knowing your way around ‘the big C’ in veterinary practice
Authors: Currie Mairead
Published: March 2020

When people hear the word cancer in relation to a loved one, the wave of emotion that follows can be devastating. Due to the complexity of oncology, a suspected or confirmed diagnosis often leads to large volume of information detailing the next steps and possible options. Pets are no exception and when owners are required to make emotive decisions with limited time to deliberate, it is the responsibility of the veterinary surgeons and nurses to provide up-to-date knowledge, guiding them to make the best decision both for themselves and their pets. This article explores the prevalence of neoplasia and the role of the first-opinion practice in diagnosis and treatment of neoplasms in pets. It also looks at the recognition of paraneoplastic syndromes in cancer patients and the importance of implementing gold-standard chemotherapy protocols. Understanding key aspects of the most common neoplasms in dogs and cats and their potential treatments helps to manage owner expectation in the practice setting. However, the ability to empathise and convey the importance of quality of life is also fundamental when supporting an owner and their animal through their cancer journey.
A prospective cross-sectional survey of UK-based dog owners to explore canine handling intolerances and owner willingness to disclose these to veterinary professionals
Authors: Campbell E , Connor M , Buckley LA
Published: March 2020

Background:

Canine handling intolerances (CHI) can be problematic for veterinary professionals (VPs), particularly when not disclosed by owners.

Aims:

This study explored apparent prevalence of CHI during veterinary practice visits, owner willingness to disclose intolerances to VPs and their beliefs as to responsibilities for disclosure and risks of non-disclosure.

Methods:

Using a prospective cross-sectional study design, an online, social media-based survey was distributed, which generated 471 usable responses over 4 months.

Results:

The majority (60.7%) of dogs had CHI. Most owners (78.1%) would definitely alert VPs to CHI, 90.5% believed it was primarily the owners’ responsibility to disclose, with non-disclosure perceived to make procedures high risk for VPs. Veterinary practices could help prevent CHI, with puppy classes and information on canine body language which respondents also felt could be valuable.

Conclusion:

With CHI common, owners and VPs have roles to play in prevention, disclosure and management to minimise risk to VPs and ensure all parties’ welfare.
Assessment of Skills Development in Brunei Trainee Teachers: Intervention Implications
Authors: Mundia Lawrence
Published: March 2020

Teacher education has been innovated in Brunei to support the ongoing inclusive education and curriculum reforms. This survey investigated the development of essential instructional skills in initial Brunei trainee teachers. The sample consisted of 109 student teachers (71 females and 38 males). Significant mean scores (Mean ≥ 4, p< .05) and 95% confidence intervals were used to identify the levels of proficiency and enablers of success in teaching. Participants were proficient on 15 of the 28 skills measured by the Teacher Behaviors Checklist (Approachable; Confident; Effective communicator; Encourages; Enthusiastic; Flexible; Good listener; Humble; Prepared; Professional; Rapport; Respectful; Sensitive; Striving to be a better teacher; Understanding). From independent groups, T-tests and One-Way ANOVA analyses, other significant trends in participants’ performance emerged at p< .05 level of evaluation. Females scored highest on Humble and Realistic expectations while males scored highest on Understanding. Trainee teachers aged 31-35 scored highest on: Promoting critical thinking; and Providing constructive feedback, than counterparts. Participants with higher degrees (e.g. Master of Arts) scored higher on Authoritative skills than those with lower degrees (e.g. Bachelor of Arts). Trainees with teaching experience scored significantly higher on: Accessible; Knowledge about the subject matter; and Technological competence, than those with no experience. The findings suggest the need to help pre-service teachers to gain proficiency in all teacher skills to improve the quality of education in the country. Further research was recommended.

Published: March 2020

The objective of the study was to study the perceptions of student teachers and educators of an educational cluster as a tool for improving the professional competence of future educators, and to identify the cluster-related tools to be used to improve the professional competence of future educators. The project evaluation checklist for experts, a questionnaire for participants in the experiment, a semi-structured interview questionnaire to conduct with focus group respondents were used for collecting data. Data were processed using content analysis technique and SPSS Statistics v24 package. The study is quantitative, based on subjective evaluations of study participants and representatives of educational clusters, and does not aim at evaluating students’ achievements. Two simulation models of the educational cluster (“Cluster Educational Initiative” and “Cluster of Educational Opportunities for Educators 2.0”) and four educational activities for educators (discussion "Agglomeration of Subjects, Educational Institutions: Realities and Prospects”; online conference “Ukraine-Brussels - Sharing Experience in Education”; an educational tour to Finland for teachers, parents and managers in the field of education; the exchange of four teachers from two schools) was a key result of this study. It has been found that the creation of clusters for improving the professional competence of future educators and their professional advancement is now part of national education policy in Ukraine and in the world. The tools of this form of organization of educational activity are competence-oriented and aimed at deepening professional experience, development of competences of realization of life-long education, creation of own public image.
Tolerancing the surface form of aspheric microlenses manufactured by wafer-level optics techniques
Authors: Béguelin Jeremy , Noell Wilfried , Scharf Toralf , Voelkel Reinhard
Published: March 2020

Tolerancing is an important step toward the fabrication of high-quality
and cost-effective lens surfaces. It is critical for wafer-level
optics, when up to tens of thousands microlenses are fabricated in
parallel and whose surfaces cannot be formed individually. However,
approaches developed for macro-optics cannot be directly transposed
for microlenses because of differences in fabrication and testing
techniques. In particular, microlens surfaces are usually limited to
conical surfaces. Here, we study the connection between the microlens
optical performance and the form of its surface, suggesting surface
form representations suited for tolerancing purposes. Then, we compare
them with common representations for tolerancing real optical systems.
Measured surface forms of microlenses are also provided to make the
tolerancing procedure realistic. In addition, we propose term
definitions for micro-optics, complements to typical terms for
macro-optics, to ease the communication between optical designers and
manufacturers. Based on the results presented in this paper,
guidelines are proposed for tolerancing microlenses. We suggest
applying them as a first step toward a more effective and
comprehensive tolerancing procedure.
Exploration of movement artefacts in handheld laser speckle contrast perfusion imaging
Authors: Chizari Ata , Knop Tom , Sirmacek Beril , van der Heijden Ferdinand , Steenbergen Wiendelt
Published: March 2020

Functional performance of handheld laser speckle contrast imaging (LSCI) is compromised by movement artefacts. Here we quantify the movements of a handheld LSCI system employing electromagnetic (EM) tracking and measure the applied translational, tilt and on-surface laser beam speeds. By observing speckle contrast on static objects, the magnitudes of translation and tilt of wavefronts are explored for various scattering levels of the objects. We conclude that for tissue mimicking static phantoms, on-surface speeds play a dominant role to wavefront tilt speed in creation of movement artefacts. The ratio depends on the optical properties of the phantom. Furthermore, with the same applied speed, the drop in the speckle contrast increases with decreasing reduced scattering coefficient, and hence the related movement artefact increases.
Molecular and histopathological identification of ovine neosporosis (Neospora caninum) in aborted ewes in Iraq
Authors: Al-Shaeli Sattar J. J. , Ethaeb Ali M. , Gharban Hasanain A. J.
Published: March 2020

Aim: The objective of the present study was to detect Neospora caninum DNA in the placenta of sheep and evaluate the association of risk factors to polymerase chain reaction (PCR) positive and histopathological analysis of the placenta and fetal tissue samples of aborted fetuses. Materials and Methods: Fresh placenta from 51 aborted ewes was collected for PCR assay. Placental and fetal tissues of aborted fetuses, including brain, heart, liver, lung, and thymus, were collected for histopathological analysis, besides the risk factor data were obtained during the time of sampling. Results: From 51 placentas examined by PCR, 13.73% appeared positive to N. caninum DNA. The relationship between PCR positive and the risk factors revealed a significant difference (p<0.05) in age of the dam, fetal age, feed source, water source, and the presence of other animals at farm, whereas the type of birth, stillbirth, and size of flock showed insignificant difference (p>0.05). Histopathological investigation of placental and fetal tissues of positive samples showed tissue cyst-like structure, necrotic foci, and infiltration of mononuclear cells. Other lesions were thickening in chorionic plate in placenta, severe vacuolization and death of neurons, microgliosis, demyelination, edema, and proliferation of astrocytes in brain. In addition, fibrous and fat deposition with stenosis in the heart, parenchymal necrosis, severe atrophy, vacuolization and hyalinization of hepatocytes, megakaryocyte, portal fibrosis in the liver, and interlobular septal thickening in lung without obvious lesions is seen in the thymus tissue samples. Conclusion: This is a unique study that confirmed N. caninum DNA in the placenta of aborted ewes in Iraq using PCR assay. Histopathological analysis of some aborted fetuses organs could provide a more confirmatory and reliable data for a significant role of neosporosis in increasing the rate of abortion in sheep, while the clinical data of risk factors could be used to control the transmission of N. caninum infection.
A comprehensive analysis of the parameters in the creation and comparison of feature vectors in distributional semantic models for multiple languagescation of inertial and magnetic sensors in online pattern recognition problems
Authors: Dobó András
Published: March 2020

Measuring the semantic similarity and relatedness of words is important for many natural language processing tasks. Although distributional semantic models designed for this task have many different parameters, such as vector similarity measures, weighting schemes and dimensionality reduction techniques, there is no truly comprehensive study simultaneously evaluating these parameters while also analysing the differences in the findings for multiple languages. We would like to address this gap with our systematic study by searching for the best configuration in the creation and comparison of feature vectors in distributional semantic models for English, Spanish and Hungarian separately, and then comparing our findings across these languages. During our extensive analysis we test a large number of possible settings for all parameters, with more than a thousand novel variants in case of some of them. As a result of this we were able to find such configurations that significantly outperform conventional configurations and achieve state-of-the-art results.
Application of the Hybrid Approach to Chronic Total Coronary Occlusion Percutaneous Coronary Intervention
Authors: Tajti Péter
Published: March 2020

Percutaneous coronary intervention (PCI) for chronic total occlusion (CTO) continues to evolve constantly with developing equipment and techniques. The hybrid approach to CTO PCI advocates dual coronary injection, careful and structured review of the angiogram, and flexibility. Use of all crossing strategies [antegrade wire escalation, antegrade dissection re-entry and retrograde approach] is encouraged, with initial and subsequent choices influenced by the CTO anatomic characteristics and the outcomes of the originally selected approach. Application of the hybrid approach to CTO PCI has been associated with good outcomes in US and European registries, although CTO PCI outcomes in non-selected populations have been less optimal with approximately 60% success rate. We analyzed the clinical, angiographic, and procedural characteristics of 3,122 CTO PCIs performed in 3,055 patients to determine the techniques and outcomes of hybrid CTO PCI in a diverse group of patients and operators in two continents (at eighteen US, one European, and one Russian centers ) enrolled in the PROGRESS-CTO (PROspective Global REgiStry for the Study of Chronic Total Occlusion Intervention, NCT02061436) registry between January 2012 and November 2017. Technical success rate was 87% and the risk for in-hospital major complications was 3%, providing important benchmarks to use when discussing with patients and providers the risk/benefit ratio of CTO PCI. The final successful crossing strategy was antegrade wire escalation in 52%, retrograde in 27%, and antegrade dissection reentry in 21%; more than 1 crossing strategies were required in 41% of the cases. CTO PCI is currently being performed with high success and acceptable complication rates among various experienced centers in the US and Europe. Bridging the gap between what is currently achieved and what can be achieved in chronic total occlusion intervention should be a major focus of upcoming research and education efforts.
Variability in the macro- and microstructure of the human brain and its importance to the investigation of neurological disorders
Authors: Király András
Published: March 2020

The exact shape of every human brain - including its micro- and macroscopic features - is as unique as a human fingerprint, resulting in inter-individual anatomical variability. In the past two decades, the understanding of this variability advanced dramatically not only at the level of sulcal/gyral patterns, anatomical features (e.g. cortical thickness, volume and shape) and extent of cytoarchitectonic areas defined at the microscopic level, but also in the anatomical and functional connectivity of the brain. The core concept within the field of brain mapping is the use of a standardized 3D coordinate frame for data analysis and reporting of findings from neuroimaging experiments. This simple construct allows brain researchers to combine (even structural or functional) data from many subjects to create group-averaged signals. Also, where the signal is robust enough to be detected in individuals, it allows for the exploration of inter-individual variance in the location of that signal. Spatial standardization requires two basic components: (i) the specification of the 3D standard coordinate space, and (ii) a mapping function that transforms a 3D brain image from “native” space to that standard space. The first component is usually expressed by the choice of a representative 3D MR image that serves as target (template or atlas). The native image is re-sampled to standard space under the mapping function that may have few or many degrees of freedom, depending upon the experimental design. The optimal choice of atlas template and mapping function depends upon considerations of age, gender, hemispheric asymmetry, anatomical correspondence, spatial normalization methodology and disease-specificity (1). In our studies we investigated some of these aspects, e.g. 1) how gender and normal aging influences brain morphology, 2) how normal hemispheric asymmetry plays a role in lateralized neurological diseases, such as cluster headache, 3) how progressive neurodegenerative disorders, such as Huntington’s disease affect the brain structure, or 4) how we can deal with inter-individual variability in case of neurosurgical interventions, such as thalamotomy in the therapy of medication resistant tremor.

Bases de mármol para un techo efímero. Preguntas sobre lo que permanece en el Museo Nacional de Bellas Artes de Buenos Aires
Authors: Isidori Julia
Published: March 2020

En este ensayo nos preguntamos cómo el Museo Nacional de Bellas Artes de Buenos Aires (MNBA) ha venido adquiriendo rasgos modernizadores, eurocéntricos y elitistas desde su fundación en 1896 al día de hoy. Para ello, nos concentramos en las colecciones permanentes —especialmente en la sala 3 de la planta baja— y analizamos la paradoja de su carácter privado en el seno de una institución pública. Mediante el relevamiento de catálogos de los últimos 50 años, análisis de la sala misma y consultas al departamento de Documentación y Archivo, notamos la coerción que ejercen los donantes de colecciones privadas sobre el museo, no solo en el relato curatorial de lo exhibido, sino también sobre lo que se decide no mostrar. En este panorama, nos preguntamos qué posibilidades tiene la institución de tomar decisiones curatoriales y de formación de públicos desde una perspectiva de Estado.
Exclusión y construcción social en Colombia: una perspectiva desde tres ritmos populares
Authors: Olave Soler Sebastian
Published: March 2020

En Colombia, las tradiciones europeas, indígenas y negras se han encontrado e influido mutuamente desde la época colonial. Sin embargo, el predominio político y económico de las élites produjo una subordinación de las prácticas musicales autóctonas y su posterior transformación. Este artículo considera la estructura social colombiana como el elemento a partir del cual las tradiciones musicales colombianas fueron modeladas. De esta manera, buscamos explicar la evolución de ciertas expresiones artísticas del país, en particular de los ritmos erigidos en símbolos nacionales como resultado de la diferenciación étnica que los ideales europeístas de las élites fomentaban.

Published: March 2020

Статья представляет результаты изучения утопических дискурсов в организациях, занимающихся исследованием Интернета. Автор проводит исторический и концептуальный анализ утопических, антиутопических и идеологических нарративов, связанных с технологиями. В частности, выявляются политическая роль утопий и идеологий и возможности их развития и трансформации. Анализ теоретических источников соотносится с хронологией развития организаций, связанных с Интернетом. Вопрос исследования заключается в том, как нарративы, связанные с утопиями, антиутопиями и идеологиями, проявляются в программах исследований в организациях, которые изучают Интернет и общество. Выявляется, что с развитием Интернета и самих организаций происходит изменение институциональных форм и утопических нарративов. Также обнаруживается, что различие утопии, антиутопии и идеологии в истории технологий связано с историей развития технологий. Утопические идеалы оказываются осквернены идеологиями государств и корпораций. Эта идея осквернения и связанная с ней идея поиска прежней утопии, представлены в исследовательских программах. Развитие утопий и идеологий продолжается по сей день, организации легитимируют себя, обращаясь к утопиям, берущим начало в идеалах и опасениях, возникших в 1960-е гг.

Banyumanik sub-district grows and develops caused by increases in population. Jalan Sukun Raya is a road commonly used by residents in Srondol Wetan Village to Jalan Setiabudi and vice versa. Sukun Raya Road Corridor is one of the local roads in Banyumanik Subdistrict.  The land use in this corridor is a commercial and service area, and settlement. Land use in the road corridor is a commercial and service area. Based on these problems, it is necessary to do trip attraction modeling. In this case, the trip attraction is needed in considering the impact of existing development, such as in the sub-center of the commercial and services area, housing, and offices. The aims of this article to develop the trip attraction model.Trip attraction modeling uses multiple linear regression analysis with the stepwise method on the commercial and service area and small scale on Jalan Sukun Raya, Banyumanik Subdistrict which is a sub-service area of the city of Semarang. Correlation and multiple linear regression analysis done based on data obtained from survey results. Data collection on Jalan Sukun Raya at peak times was carried out with field observations and interviews with established resource persons.The results showed that the sales income variable became the most influential variable on the trip attraction shown in the equation Y = 0.352 + 4.998E-7 X4. The resulting model is useful for estimating trip attraction in small-scale commercial and service areas.
A “Roman” Wedding in Vandal Africa
Authors: Schwitter Raphael
Published: March 2020

The Epithalamium Fridi is a sixth-century Virgilian cento that commemorates the marriage of the Vandal noble Fridus with his unnamed bride. Its author, the African poet Luxurius, engages in versatile poetic play fusing Virgil with multiple epithalamial models such as Statius, Claudian, and Ausonius. Through the dynamics of triangular intertextuality the centonist is able to strengthen the wedding poem's generic bonds and to connect himself and his work firmly to the classical Roman tradition. At the same time, echoes of distinctive African idiosyncrasies as prefigured by Dracontius highlight the hybrid character of sixth-century Romano-Vandal elite culture and its celebration of what appears to be a distinctive African Romanness.
Inverse relationship between autophagy and CTSK is related to bovine embryo quality
Authors: Balboula Ahmed Z , Aboelenain Mansour , Li Jianye , Bai Hanako , Kawahara Manabu , Abdel-Ghani Mohammed A , Takahashi Masashi
Published: March 2020

Improving the quality and the developmental competence of in vitro produced (IVP) embryos is an indispensable goal for assisted reproductive technology. Autophagy is a major protective mechanism for intracellular degradation of unnecessary cytoplasmic components. Autophagy ends by the fusion between autophagic vacuoles and lysosomes, allowing the degradation of the cargo by lysosomal enzymes, especially the cathepsins (CTSs). However, it is still unclear how autophagy and cathepsin K (CTSK) relate to embryo development. This study evaluated (1.) the activities of autophagy and CTSK in relation to bovine embryo quality and (2.) the effect of autophagy induction and/or CTSK inhibition on preimplantation embryo development and quality. We show here that good-quality embryos exhibited a greater autophagic activity and less CTSK activity compared to poor-quality embryos. Blastomeres of an individual embryo may vary in their quality. Good quality blastomeres showed an increased autophagic activity and decreased CTSK activity compared to poor-quality blastomeres within the same embryo at different developmental stages. Importantly, induction of autophagy and/or inhibition of CTSK improved the developmental rate (increased blastocyst and hatching rates) and the quality (increased total cell number and decreased the percentage of apoptotic cells) of IVP bovine embryos. These results demonstrate a promising approach to selectively isolate good-quality embryos and improve the efficiency of IVEP of cattle embryos.
Comparison of the effects of epidural and spinal anesthesia on analgesia and blood gases in neonates born by natural vaginal delivery: A clinical trial study

Published: March 2020

Introduction: One of the concerns of painless deliveries is the safety of neonates. This clinical trial study aimed to compare the effects of epidural and spinal anesthesia on the mortality rate of neonates.

Methods: This clinical trial was conducted in Hamadan Hospital in Iran. Ninety women, ages 18 to 45, were randomly assigned to receive epidural or subdural anesthesia. Using a checklist, the following were collected: demographic information, midwifery, hemodynamic status, mothers' pain intensity, and analyses of the baby's umbilical cord blood. The data were analyzed by SPSS version 16 for statistical analysis. Twenty-two of the patients with spinal anesthesia and epidural anesthesia were excluded from the study.

Results: There was no significant difference between the two groups in terms of age, gestational age, parity, and severity of pain before or after anesthesia. The hemodynamic status of the mothers before and during the first postoperative period was in the normal range, except that in the spinal group, a decrease in systolic blood pressure was observed in normal range compared with the epidural anesthesia group. In blood gas analysis, the mean pH, partial pressure of carbon dioxide (PCO2), and bicarbonate (HCO3) did not show significant differences between the two groups (p > 0.05). The only complications were acidosis and epidural anesthesia.

Conclusion: Based on the findings of the present study, both spinal and epidural opioids have no adverse effects on the health of neonates. However, both spinal and epidural opioid are preferred due to fewer changes in the hemodynamic changes in mothers and in umbilical cord blood gas.

Aims: to evaluate the inadequacy of food consumption and the estimated nutrient depletion caused by the use of drugs in the elderly.Methods: a cross-sectional population study, attended by 427 elderly. Food consumption was obtained from the 24-hour Food Recall Survey and the Research Dietetic History. The use of drugs was assessed by a pharmacotherapeutic questionnaire.Results: 85.8% of elderly use medications, the most prevalent inhibitors angiotensin converting enzyme inhibitor (29.2%), acetylsalicylic acid (28.7%), hydrochlorothiazide (24.4%), hydroxymethyl-glutaryl coenzyme A reductase enzyme inhibitor (17.0%), calcium carbonate (12.6%) and proton pump inhibitors (8.2%). Acetylsalicylic acid, hydrochlorothiazide and proton pump inhibitors are the drugs that possibly deplete the greatest number of nutrients. Users of hydroxymethyl-glutaryl coenzyme A reductase enzyme inhibitor, 97% could had inadequate for vitamin E; of potassium-sparing diuretics, 90.0% of inadequacy for magnesium; digoxin, 83.3% of inadequate for magnesium and 58.3% for calcium and potassium.Conclusions: the drugs most commonly used by elderly are responsible for the depletion of numerous micronutrients, often associated with a high prevalence of inadequate consumption, which may cause possible nutritional deficiencies.

Efectividad de bolos homeopáticos intraruminales sobre el recuento de células somáticas de origen bacteriano en vacas lecheras de doble propósito
Authors: Saldivia-Paredes Manuel A , Cornejo-Paredes Cristopher A
Published: March 2020

El objetivo principal de esta investigación fue medir la efectividad de bolos intraruminales de origen homeopático, sobre el recuento de células somáticas en vacas de doble propósito diagnosticadas con mastitis subclínica y clínica pertenecientes a predios de la región de Los Lagos, Chile. El presente estudio fue realizado en 5 predios lecheros, bajo un método no probabilístico se eligió un total de 30 muestras, 6 por cada predio, de las cuales 4 fueron “caso” y 2 “control”, dando un total de 20 y 10 respectivamente para cada grupo. Se eligieron a 6 vacas por predio con mayor RCS, estando sanas clínicamente y positivas a la prueba LDH, 4 fueron grupo “caso”, a las que se les aplicó el producto el día 0, mientras que las 2 vacas restantes fueron grupo “control” (sin aplicación de producto). Las pruebas se realizaron en base al recuento de células somáticas (RSC) (control lechero), y test de lactato deshidrogenasa en leche (LDH), midiendo estas 2 pruebas diagnósticas  al día 0 y al cabo de 21 días.  Los resultados del estudio muestran una efectividad cercana al 88% disminuyendo el RCS por debajo de los 200.000 CS/ml.
Impacto socioeconómico de la variabilidad climática en pesca y turismo: antecedentes y propuesta metodológica
Authors: Moreno-Díaz Mary L.
Published: March 2020

Introducción: La variabilidad climática tiene efectos importantes sobre las diferentes actividades económicas que se desarrollan en zonas costeras y que emplean servicios ecosistémicos para su funcionamiento. Actualmente, no existen metodologías integrales que permitan realizar un proceso de valoración teniendo en cuenta todas las variables y las interacciones entre ellas. Objetivo: Proponer una aproximación metodológica que incluya de manera integral las diferentes etapas en el proceso de valoración económica de servicios ecosistémicos en zonas costeras, ante la variabilidad climática. Métodos: Se realizó una revisión bibliográfica, consulta a expertos y se empleó un ejemplo de aplicación usando la actividad turística de buceo con tiburones martillos en la Isla del Coco. Resultados: La aproximación metodológica propuesta inicia con la caracterización socioeconómica y ambiental de la actividad que emplea el recurso natural como insumo, posteriormente se realiza una identificación y caracterización de las variables ambientales que afectan el recurso natural y los efectos que la variación de este recurso tiene sobre la actividad económica. Conclusiones: Las variables que conforman el sistema climático, que tienen relación con los recursos naturales y las actividades económicas, al ser influenciadas por fenómenos externos, producen efectos que deben ser analizados por medio de aproximaciones metodológicas integrales, dentro de las cuales uno de los pasos es la metodología de valoración, que permitan generar recomendaciones de política que contribuyan a minimizar esos efectos.
Dynamic and growth of the forests of the Isla del Coco National Park, Costa Rica

Introduction: Islands are essential for world biodiversity. Isla del Coco National Park is an oceanic island in which a tropical rain forest grows; however, its ecology and the effect of introduced species are poorly understood. Objective: To evaluate the mortality, recruitment, regeneration, and growth of forest canopy species. Methods: We measured 15 permanent sampling plots (PSP), nine in the Premontane Pluvial Rainforest (PPR), and six in the Cloud Forest (CF); trees with DBH > 5 cm (diameter at breast height) were measured. The sampling regeneration was done within every PSP, along two transects of 1 X 50 m. Data analyses were performed using data obtained in 2006 and 2012 as baseline. Results: In the period 2012-2017, the annual mortality rate in the PPR was 5.75 % and for CF 6.31 %. The yearly recruitment rate in the PPR was 5.38 %, and 5.90 % for CF. For the PPR the total registered regeneration was 5 656 individuals and 8 700 for the CF. Sacoglottis holdridgei reported the highest mortality and the lowest values of recruitment and regeneration. Forest structure fits the inverted J model for most of the tropical forests. Sacoglottis holdridgei define the forest population structure above DBH > 20 cm. But, diameters under 20 cm are strongly influenced by H. succosa, because it reported the highest abundance of regeneration and recruitment. The annual average increase in diameter between forest was statically different (p = 0.0414; N = 15), 0.36 cm/year in the PPR, and 0.33 cm/year the in CF. Conclusions: The PPR and CF differ in the patterns of mortality, recruitment, and regeneration, confirming the uniqueness of these ecosystems. More successful regeneration of H. succosa will lead to changes in structure and composition of forests, mainly PPR. The changes in forest structure will have a strong impact on epiphytic flora, microclimate conditions, and bird nesting such as Gygis alba (White Tern) due to the loss of mature trees of Sacoglottis. The low regeneration of S. holdridgei is associated with the presence of introduced herbivores, their management is needed for restoring the forest.
La diversidad del Orden Diptera de la Isla del Coco representada en la colección de artrópodos del Museo Nacional de Costa Rica y otras colecciones
Authors: Méndez-Soto Maricelle
Published: March 2020

Introducción: La Isla del Coco es una isla oceánica que, a pesar de su reconocida biodiversidad, ha sido poco estudiada en cuanto a su entomofauna, particularmente del Orden Diptera. Objetivo: Presentar la diversidad de “moscas” que alberga la Colección de Artrópodos del Museo Nacional de Costa Rica (MNCR), proveniente de recolectadas realizadas entre 1994-2013. Métodos: Se hizo un análisis de los 2129 registros físicos y digitales de Specify del MNCR y otras bases de datos, así como de la literatura. Resultados: Dentro del MNCR se encuentran 30 familias, 43 géneros y 28 especies; trabajo de determinación taxonómica realizado por un conjunto de más de 30 expertos en el grupo. Existe material tanto en la colección del MNCR y así como en Museo de Zoología de la Universidad de Costa Rica y otras instituciones fuera del país. Conclusiones: El esfuerzo de muestreo se ha concentrado solamente en un sector de la isla, por lo que se proyecta una diversidad mayor si se amplían los esfuerzos. Es fundamental mantener esfuerzos planificados en el ámbito de la investigación taxonómica de la fauna entomológica, que permitan ampliar el conocimiento de la diversidad presente.
