Henri Pittier, el primer científico conservacionista en Costa Rica
Authors: Hilje Luko , Dauphin Gregorio 
Published: July 2022

Entre los científicos que arribaron a Costa Rica en el siglo XIX, el más conocido es el suizo Henri Pittier, debido a sus incontables y ricos aportes, de carácter pionero, en disciplinas como la geografía, la climatología, la cartografía, la botánica, la etnografía y la arqueología. Además, después de partir y permanecer casi 14 años en EE.UU., se instaló en Venezuela, donde también realizó una excepcional labor científica hasta el final de su vida, a los 92 años de edad. Ello explica que, a lo largo de los años, no cesen de aparecer artículos en los que se le cite, así como semblanzas e incluso libros acerca de él, además de que en el año 2020 vio la luz el exquisito y cálido documental La Gyranthera. Traces de Henri Pittier Explorateur, de la cineasta Mürra Zabel. Es de esperar que, en algún momento, se escriba un libro amplio, integrador y comprensivo sobre su vida y su obra completa, en Suiza, Costa Rica, EE.UU. y Venezuela.

[Introducción]: Los estudios sobre gestión adaptativa en sistemas socioecológicos reconocen que los recursos naturales (p.ej., bosques) no se encuentran aislados, sino entretejidos en sus ecosistemas con componentes sociales, institucionales, económicos y políticos. Este estudio aborda la gestión adaptativa a partir del aprovechamiento de las palmas camedor (Chamaedorea quezalteca), en la Reserva de la Biosfera La Sepultura (RIBESE), Chiapas, México. El recurso de las palmas camedor es considerado como el producto forestal no maderable (PFNM) más aprovechado por comunidades rurales e indígenas de América Central. La contribución del estudio va más allá de los aspectos ecológicos de la palma, se abordó como un sistema socioecológico (SSE) complejo y dinámico. [Objetivo]: Analizar la gestión de las palmas camedor a través de un análisis del ciclo de renovación adaptativa de los SSE. [Metodología]: Se aplicaron entrevistas semiestructuradas a actores clave, un taller participativo con productores de palmas, y la aplicación empírica del modelo del ciclo adaptativo propuesto por Holling. [Resultados]: Se identificaron tres etapas representadas por ciclos adaptativos: 1) una explotación no regulada de poblaciones silvestres de palmas (1960-2004); 2) regulación y participación local en el manejo y conservación de las palmas (2005-2014); y 3) cogestión y reorganización comunitaria para el aprovechamiento sustentable de las palmas (2015-2020). [Conclusión]: El proceso evolutivo y adaptativo del SSE ha sido influenciado por los cambios intrínsecos en el desarrollo comunitario y por factores externos, como el mercado internacional de las palmas; políticas públicas; programas de conservación y desarrollo, y la interacción de actores gubernamentales y no gubernamentales.

Published: July 2022

Resumen
La Sociedad actual se caracteriza por su carácter complejo, interdependiente, dinámico e informacional en la que concurren personas físicas y personas jurídicas que se integran en un medio ambiente político, social, económico, ecológico, físico-finito y con recursos limitados. En este contexto se van consolidando distintas macrotendencias que hace germinar nuevos modelos económicos, políticos y sociales que obligan a las personas a una adaptación permanente de sus competencias, necesarias para evitar que se generen polarizaciones, exclusiones y brechas de alfabetización que deben abordarse desde nuevas coordenadas. Las universidades que han sido lugares de generación y de transmisión de conocimiento deben entender, aceptar y adaptarse al contexto emergente y anticipar futuras situaciones ya que de no hacerlo sus misiones quedarán abocadas a la irrelevancia y serán desplazadas como agentes y referentes educativos. En este documento se hace referencia a este proceso de cambio y se valoran propuestas emergentes en las que ya se está trabajando construir un futuro sostenible y responsable.

Authors: Widiadi Aditya Nugroho 
Published: July 2022

Indonesia is a disaster-prone country. History has proven that this country has been hit by various types of natural disasters for a long time. Unfortunately, disaster mitigation efforts through disaster education seem to be still not optimally conducted in Indonesia. There are only two subjects that formally contain the content of disaster education. Meanwhile, other subjects, including Indonesian history, are not required to provide students with the content of disaster education. Even though, there are many historical events in the subject of history of Indonesia that discuss the occurrence of disasters in Indonesia. Another challenge is how to integrate disaster education in history learning. One alternative method offered by this paper is through ADIT learning model. Indonesia merupakan negara yang rawan bencana. Sejarah telah membuktikan bahwa negara ini telah dilanda berbagai jenis bencana alam sejak lama. Sayangnya, upaya mitigasi bencana melalui pendidikan kebencanaan tampaknya masih belum maksimal dilakukan di Indonesia. Hanya ada dua mata pelajaran yang secara formal memuat muatan pendidikan kebencanaan. Sedangkan mata pelajaran lain, termasuk sejarah Indonesia, tidak wajib membekali siswa dengan muatan pendidikan kebencanaan. Padahal, banyak peristiwa sejarah dalam mata kuliah sejarah Indonesia yang membahas tentang terjadinya bencana di Indonesia. Tantangan lainnya adalah bagaimana mengintegrasikan pendidikan kebencanaan dalam pembelajaran sejarah. Salah satu alternatif metode yang ditawarkan oleh makalah ini adalah melalui model pembelajaran ADIT.

Published: July 2022

This research focuses on the significance of responding to massive changes in historical learning. However, various learning issues arise, resulting in a lack of understanding of the content by students, particularly those who have not previously understood Indonesian History material well. This is due to dense learning materials and the use of ineffective learning media. As a result, students struggle to understand the material in the text-book. Based on this, learning innovations that facilitate learning Indonesian history are required. One of them is the study of prehistoric people's lives, which includes historical values, using augmented reality visual media. This media has the ability to clarify ideas, increase students' imagination and interest, and thus increase understanding of the material. Augmented reality packaged digitally can directly create interaction between students and 3D objects, facilitating information delivery. The goal of this study is to create learning media ARMAPS (Augmented Reality Maps) and evaluate their effectiveness. A 4D model was used in this study, which included: (1) definition, (2) design, (3) development, and (4) dissemination.

Published: July 2022

Background and purpose: Spotted ash looper, Abraxas pantaria (Lepidoptera: Geometridae) causes defoliations of narrow-leaved ash (Fraxinus angustifolia) in Croatia, mainly in Krka National Park. Since controlling pests with insecticides is not possible in protected areas, biological pest control might be a valuable option. The first step in the study of its application is the research on hosts and their natural enemies. Not much is known about the parasitoid spectrum of A. pantaria in Croatia, so the aim of this research is to identify the parasitoid species which could influence the population density of this potential forest pest. Materials and methods: Pupae of A. pantaria were studied in 2010 at several locations along the River Krka in Krka National Park. This area was chosen because total defoliation of ash was observed in 2010. Results and conclusions: Five tachinid species were reared from Abraxas pantaria: Phryxe nemea, Bactromyia aurulenta, Senometopia sp., Pales pavida and Eurysthaea scutellaris. All species are generalist parasitoids. Phryxe nemea is the first record for this host.

Authors: Batistić Mirna , Garić Rade , Morović Mira 
Published: July 2022

Background and Purpose: Here we presented changes in the non-crustacean zooplankton community in the years characterized by the large scale changes in the thermohaline circulation in the East Mediterranean known as the Eastern Mediterranean transient (EMT) and stronger inflow of colder and less saline Modified Atlantic Water (MAW) into the Adriatic Sea. Material and Method: Monthly samplings from February 1995 to February 1996, were performed at fixed station Stončica near the Island of Vis in the open oligotrophic Middle Adriatic waters. Zooplankton samples, taken vertically from 100 m to the surface using a Nansen net with 125-µm mesh size were analyzed in detail for the following zooplankton taxa: Hydromedusae, Calycophorae, Ctenophora, Pteropoda, Heteropoda, Polychaeta and Chaetognatha. Results and Conclusions: Among the investigated non-crustacean zooplankton three species were registered for the first time, while one species reappeared after years of absence. Compared with earlier data there was a dramatic change in dominant species of calycophoran medusae, pteropods and polychaetes. Data presented herein provide baseline information that is essential for the evaluation of impact of hydroclimatic changes on the zooplankton community, which started in the East Mediterranean in the 1990s and are still on going. Keywords: zooplankton, hydroclimatic changes, Middle Adriatic

Published: July 2022

Background and purpose: Producing of reliable information about pharmacological activity of new chemical entities is essential in early stages of drug discovery and development. There is a continuous need for improvement of existing in vitro technologies, in order to get more accurate and more predictive biological data (and for compounds selection) in pre-clinical screening methods and models. Materials and methods: Two-dimensional (2D) cell cultures, in comparison with original tissues, does not fully reproduce in vivo cell growth and differentiation. Therefore, significant efforts have been made toward the development of more realistic three-dimensional (3D) in vitro cell culture models that would better mimic tissue physiology. Results: Two-dimensional (2D) cell cultures, in comparison with original tissues, does not fully reproduce in vivo cell growth and differentiation. Therefore, significant efforts have been made toward the development of more realistic three-dimensional (3D) in vitro cell culture models that would better mimic tissue physiology. Basic concepts and advantages of 3D cell cultures, as well as different approaches in technologies that enable the cell growth in 3D will be presented here. Possible applications of 3D cell culture in drug discovery will be discussed, and example of formation of spherical growth of three different human breast cancer cells (MDA-MB-231, SK-BR-3 and T-47D cells) in 3D format will be shown. Conclusions: Although biological significance of obtained data from 2D and 3D cell cultures is still poorly understood, discrepancy of compunds activity illustrated importance of implementation 3D cell culture assays in early part of drug discovery process. Keywords: new anticancer drugs, in vitro assays 2D and 3D cell cultures, 3D cell cultures technologies, applications in drug discovery

Authors: Schwerk Axel , Klich Daniel , Wójtowicz Elżbieta 
Published: July 2022

Background and purpose: Teratological cases in insects can be of different characteristic, quite often they are bifurcations, for example of antennal segments or parts of the legs. The aim of this paper is to report a remarkable case of leg duplication in Carabus violaceus L.

Materials and methods: In the context of an interdisciplinary monitoring in the frame of a conservation project on the European bison (Bison bonasus (L.)) in Poland the carabid fauna (Carabidae) on areas grazed by this species was studied using pitfall traps in the Pszczyna forest, located in Silesia Province, to the south of the town Tychy. The traps were located inside a mixed fresh coniferous forest, with domination of Scots pine (Pinus sylvestris L.).

Results: Among the carabids gathered a remarkable teratological female specimen of the species Carabus violaceus L. with repeated anatomical duplications on the right front leg was collected.

Conclusions: The repeated incident of bifurcation suggest a genetic base of the teratology. An increased rate of teratological cases may have potential as bioindicator.
