Sustainable Development of Low-Carbon Supply Chain Economy based on the Internet of Things and Environmental Responsibility
Authors: Ma Zhijun , Yang Xiaobei , Miao Ruili , Yue Yiji
Published: September 2024

To reach carbon peak and neutralization, a low-carbon supply chain is a clean practice that turns supply chain management into a green economy. This approach aims to decrease energy consumption and pollution and accomplish sustainable development across the supply chain. The worldwide logistics business has transformed into an intelligent service provider to the adoption of real-time management tactics made possible by the Internet of Things (IoT). The impact of the IoT on China’s logistics industry and its impact on the environment are examined in this article. This study, a new model is proposed for incorporating the most popular carbon regulations to accomplish the above advantages and create a more sustainable supply chain. This work discusses how to implement effective carbon regulating systems to promote sustainable development. Main contribution of this research is considering the impact of carbon regulations on environmental benefits and enhancing regional development levels in a supply chain network design challenge. In addition, judgments on cargo consolidation are used to lessen financial and ecological footprints. This article examines and analyses the development of a low-carbon supply chain from the two aspects of the IoT and environmental responsibility to better support the sustainable growth of a low-carbon supply chain economy and raise people’s standards of living. Research results show that the industrial scale of China’s low-carbon supply chain economy is expected to exceed 300 billion by 2025. At present, there are still economic development barriers, but integrating the IoT technology and environmental responsibility consciousness into economic development, it has the potential to strengthen the development of a low-carbon supply chain and improve the conditions for long-term, sustainable growth.

Published: September 2024

Surface changes of biomaterials are essential for aligning with the biological system’s dynamics and enhancing the effectiveness of bioimplants. Customized surface alterations based on the material’s bonding ability, biocompatibility, and interactions with host cells may have a substantial impact. This investigation uses hydroxyapatite (HAp) with 0, 10, 20, 30, and 40 wt% silver as a thin coating layer on stainless steel (SST) 316 L by electrophoretic deposition preparation at 30 V and 30 min coating duration. The coating’s crystallinity, morphology, and microstructure have been investigated using structural characterization methods such as X-ray diffraction, Scanning electron microscopy, and energy dispersive spectroscopy. The resistance to corrosion of uncoated and coated SST substrates has been assessed using potentiodynamic polarization experiments. The results show that the HAp-nanosilver coating layer increases the SST’s resistance to corrosion in Ringer solution. The HAp 10% silver-coated SST displays a reduction in corrosion current density. These further demonstrate the potential for using HAp and silver-coated stainless steel as a surgical instrument to increase biocompatibility and resistance to corrosion.
Constructing elderly patients’ agency through conversational storytelling
Authors: Zhu Dongyi
Published: September 2024

Conversational storytelling in doctor–patient interactions has become an important channel for doctors to understand patients’ experiences of health and illness. This study explores how storytelling is used as a resource to influence patient’s agency in history-taking, especially in the sequential development of elderly Chinese patients’ storytelling. The study draws on 39 conversations with four doctors and twelve elderly patients. Examples are selected from five contrasting extracts to see how elderly Chinese patients employ storytelling to reveal agency accomplished in doctor–patient interaction, especially among the patients’ orienting to the “sick role”. By specifying the agency engagement, this study also helps us appreciate that doctors should be encouraged to attend to patients’ storytelling and assert patients’ agency as ways to attend to their concerns and come to a deeper understanding of their conditions, to facilitate holistic medical encounters.
Towards a theory of linguistic curiosity: applying linguistic frameworks to lingcomm and scicomm
Authors: McCulloch Gretchen , Gawne Lauren
Published: September 2024

Linguistics communication (lingcomm) is uniquely placed as a branch of science communication (scicomm), as lingcomm practitioners can reflexively draw on our own discipline of linguistics to further our understanding of effective communication practices with broader audiences. In this article we cut across various sub-disciplines of linguistics to look at syntactic, semantic, and discourse practices that make for compelling communication. We refer to this as the way a text incites curiosity, or the value of “curiosity”, by analogy with “grammaticality” and “felicity” as linguistic concepts. We look at an example text with high curiosity in scicomm, before highlighting key linguistic features of curiosity. We also show how we implement these in our own lingcomm work, and discuss the implications for effective lingcomm. We conclude with potential avenues for exploring curiosity in scicomm and lingcomm, and the importance of linguists contributing to public understanding of language.
American sweet potato and Asia-Pacific crop experimentation during early colonisation of temperate-climate Aotearoa/New Zealand
Authors: Barber Ian G. , Benham Rebecca Waikuini
Published: September 2024

The American sweet potato (Ipomoea batatas) is a globally important comestible crop that features prominently in Polynesian lore; however, the timing and mode of its Oceanic transplantation remain obscure. New research from the Māori cultivation site M24/11 in Aotearoa/New Zealand, presented here, offers a re-evaluation of evidence for the early use and distribution of the sweet potato in southern Polynesia. Consideration of plant microparticles from fourteenth-century archaeological contexts at the site indicates local cultivation of sweet potato, taro and yam. Of these, only sweet potato persisted through a post-1650 climatic downturn it seems, underscoring the enduring southern-Polynesian appeal of this hardy crop.

The European Right to Social and Medical Assistance
Authors:   Jesuit University Ignatianum, Krakow, Poland, Świątkowski Andrzej Marian
Published: September 2024

The provisions of Articles 11 to 17 of the European Social Charter and Articles 23, 30 and 31 of the Revised European Social Charter establish social security standards universally applicable in Europe. Among these provisions, Article 13 is important, which defines common standards of broadly understood social security. Establishing and maintaining these social security systems is the responsibility of the authorities of the Member States forming the Council of Europe. These countries have an obligation to improve their national social security systems. The standards for assessing the conformity of national social security systems in Europe are set, in the case of countries that have ratified the European Charter of Social Rights, by ILO Convention No. 102 or, in the case of countries that have committed themselves to the 1996 Revised European Social Charter, by the European Code of Social Security. In particular, the standards contained in Article 12 paragraph 4 of both Social Charters of the Council of Europe are the basis of the most widely understood principle of social protection on the European continent. This principle applies to all citizens of the Member States of the Council of Europe, regardless of their place of residence on the European continent. The provision of Article 12 paragraph 4 letter ‘b’ of the European Social Charter is a legal norm that has a chance to initiate the process of free movement of insured persons between the states forming the Council of Europe. In the case of countries belonging to the European Union, the Committee of Social Rights requires that reports on the application of social security standards include information on the movement of insured persons from non-EU countries and their legal situation in matters relating to the granting, maintenance and restoration of rights to social benefits while observing the principle of including periods of insurance in other Council of Europe countries into the insurance period. The achievements of the Committee for Social Rights in matters relating to the establishment and observance of social security standards in Europe, presented in this article, justify the thesis that the Council of Europe has adopted and strives to implement high and effective standards of social protection of the insured.

Published: September 2024

Challenges for educational institutions can be characterized by increasing institutional competition and the number of educational institutions offering services. The number of existing institutions causes the high competitiveness of each institution. Educational institutions must build a good brand image to influence prospective students and the public to choose the educational institution. Branding image reflects the quality of superior educational institutions, good academic programs, qualified educators, and supporting facilities and infrastructure. The formulation of the problem in this literature review is what is the role of public relations in improving school image and how is the public relations strategy in improving school image. The writing of this article uses a literature study approach that explores information and processes research materials through recorded events that have been reviewed in scientific works in the form of writings, images, or monumental works of a person. The data sources studied were books, journals, magazines, documents, newspapers, research report articles, and information sourced from the internet. Public relations is a comprehensive and integrated strategy regarding the main activities of an institution. In this context, Public Relations is required to be able to shape the values of understanding attitudes to public behavior to be in line with the needs of the institution.  The strategy used in packaging public communication messages that contain more about what and who and what are the benefits of the existence of an institution. This ability needs to be supported by public relations programs and activities, especially in order to build the image of educational institutions in the eyes of the community, which consists of marketing and corporate programs and activities. The role of public relations in educational institutions, at least, consists of several roles, namely: communicator, expert advisor, intermediary / counseling, and problem-solving facilitator.

Authors: Pérez Barría Claudio Hernán
Published: September 2024

This article provides a historical journey that begins with the conquest and colonization of Abya Yala to the present. At the start of the trajectory, the systematic violence exercised by the European invaders towards the inhabitants of the aforementioned territory is made visible, which had an effect on the epistemological and symbolic dimensions, physically and ideologically subjugating the original cultures, with consequences that are still evident to this day, this being visible in the Chilean educational system in general, and, specifically, in religious school education, which inherit and therefore prolong the colonizing episteme, thus a decolonizing action is imperatively proposed.

Published: September 2024

Acutely decompensated heart failure is one of the leading causes of hospitalisation worldwide, with a significant majority of these cases attributed to congestion. Although congestion is commonly mistaken for volume overload, evidence suggests that decompensation can occur without significant water accumulation, being attributed to volume redistribution. Yet, the distinction between intravascular and extravascular congestion in heart failure often blurs, as patients frequently exhibit overlapping features of both, and as patients may transition between phenotypes over time. Considering that differentiation between intravascular and extravascular congestion can lead to different management strategies, the aim of this review was to delineate the pathophysiological nuances between the two, as well as their correlation with clinical, biochemical and imaging indices.

Authors: Vaca Portillo Angie Cecilia , Osorio Mora Oswaldo
Published: September 2024

La uchuva (Physalis peruviana L.) es reconocida en los mercados nacional e internacional como una fruta exótica y con un alto valor nutricional. Sin embargo, su corta vida útil y las pérdidas postcosecha afectan su comercialización. El objetivo de esta investigación fue desarrollar la formulación de un recubrimiento comestible, a partir de un diseño de superficie de respuesta Box-Behnken, variando la concentración de quitosano (1, 1,5 y 2 %) (p/p), cera de abeja y glicerol (1, 2 y 3 %) (p/p), para extender la vida útil de los frutos. La pérdida de peso, la firmeza, el índice de color y la tasa de respiración fueron las variables de respuesta. Los modelos polinómicos cuadráticos generados fueron adecuados para explicar los efectos de las concentraciones de quitosano, cera de abeja y glicerol. La validación experimental confirmó la idoneidad de la formulación del recubrimiento para uchuva mediante la metodología de superficie de respuesta con quitosano al 1,33 %, cera de abeja al 2,14 % y glicerol al 1,29 %. El recubrimiento mantuvo las propiedades fisiológicas y físicas de la uchuva hasta 15 días en temperatura ambiente.

Published: September 2024

An ecophysiological study was carried out in a mixed pasture composed mainly of grasses Megathyrsus maximus and Brachiaria arrecta in the South of Lake Maracaibo, Venezuela, under tropical rainforest conditions, with the purpose of determining the possible beneficial association between these tropical grasses. Seven paddocks were sampled, taking three subsamples of each, both in the dry and wet season; the technique consisted of throwing a random metal frame in a zigzag shape. The chlorophyll content index (CCI) and the foliar and root dry weight were measured. Data were analyzed using the Mann-Whitney U nonparametric statistical test. No differences were found for the root dry weight variable between the two seasons for the two species. Regarding the leaf dry weight, B. arrecta did not show differences between the seasons, while for M. maximus, it was higher in the wet season. The CCI in B. arrecta did not show differences between the seasons, while in M. maximus, it was higher in the wet season. According to the results, it was concluded that this association is beneficial because M. maximus favors B. arrecta possibly due to a nurse effect, which allows this species to have less abiotic stress and therefore greater carbon fixation and greater availability of plant biomass during the most critical season, namely the dry season.

Comparison of maize performance between doubled haploids and different selfing generations in the Mexican subtropics
Authors: Vargas Escobar Ever Andrés , García Dávila Mario Augusto
Published: September 2024

Maize (Zea mays) hybrid breeding programs are increasingly adopting double haploid (DH) technology to enhance efficiency and meet the growing demand for food in the face of population growth and climate change. However, in developing countries such as those in subtropical regions, the utilization of DH technology is still limited. This study aims to evaluate the potential benefits of incorporating this technology into both new and established maize breeding programs. Using a pedigree selfing population from the CIMMYT Genebank, DH lines were developed and compared to the conventional pedigree selfing method through a line-by-tester evaluation. Fifteen DH lines and fourteen lines from each of the S2, S4, and S6 selfing generations were subjected to multilocation yield trials in the subtropics of Mexico. The results showed that it took three years for the S1 population to identify DH lines with 100 % homozygosity and the highest general combining ability (GCA), which was one year earlier than the S6 lines (98,4 % homozygous). DH lines exhibited more genotype-by-environment interactions (GxE) compared to S2 testcrosses but demonstrated similar heritability to the S6 generation. Significant statistical differences were observed between the DH evaluations and the S4 and S6 testcrosses, while no significant difference was found between the S2 and DH evaluations. Based on these findings, a gradual implementation of DH technology in hybrid breeding programs is recommended. However, the conventional pedigree method should not be abandoned entirely, and testing in selfing generations, particularly in S6, remains crucial. This study provides a statistical comparison of DH versus the conventional pedigree method using a line-by-tester approach, contributing valuable insights for plant breeders and researchers in the field of maize breeding.

Published: September 2024

El establecimiento temprano de los cultivos permite definir la época con menor riesgo para la siembra. De tal manera, el objetivo de este estudio es establecer las componentes de la estación de crecimiento para 2 épocas del cultivo de arroz en el sur del Valle del Cauca, Colombia, a los niveles del 20, 40, 60 y 80 % de probabilidad de excedencia y no excedencia. Para ello, se usaron 3 criterios: a) lluvia acumulada por 5 días que supere los 20 mm, b) lluvia acumulada por 5 días que supere los 20 mm; aceptando al menos 3 días de sequía y c) el total de 5 días de lluvia que supere la mitad de la evapotranspiración de referencia. Con la distribución normal estándar inversa se estimaron los componentes de la estación de crecimiento, lo cual arrojó que la fecha más probable de siembra se da al 80 % de probabilidad de no excedencia para ambas épocas de crecimiento. Igualmente, se representaron los resultados en mapas, que permitieron observar que la estación La Independencia es más representativa de la zona de estudio. El inicio de la temporada lluviosa (ILL) se estableció después del inicio de la época de crecimiento, con un 80% de probabilidad de no excedencia. Respecto a la duración de la época de crecimiento, fue de mínimo 121 y 114 días para la primera y segunda época de crecimiento, respectivamente. Con base en el balance hídrico gráfico se estimó la duración del déficit de lluvias (DDLLL) y se identificó que la estación Ingenio Miranda tuvo 66 días de sequias y La Independencia fue la ubicación con menos días secos, entre épocas de crecimiento.

Published: September 2024

El maracuyá (Passiflora edulis f. flavicarpa) es una de las principales especies frutales de la región neotropical y Colombia es uno de sus principales productores con cerca de 165 893 toneladas al año. A pesar de esto, el cultivo es afectado por múltiples problemas fitosanitarios, como la secadera causada por Fusarium solani f. sp. passiflorae (fusariosis), la cual puede causar pérdidas de cosecha hasta del 70 %. El objetivo de esta investigación fue estimar el efecto de cuatro portainjertos de Passiflora (P. alata, P. maliformis, P. quadrangularis, y P. edulis f. edulis) tolerantes a la secadera, en el crecimiento vegetativo de plántulas de maracuyá. El estudio fue realizado en la estación experimental de Agrosavia en Palmira, Valle del Cauca (Colombia), bajo un diseño completamente al azar constituido por seis tratamientos y seis repeticiones. Los datos fueron sometidos a pruebas de rango múltiple y comparación de medias de Dunnett (p < 0.05). Se encontró que los portainjertos evaluados presentaron 100 % de prendimiento y una compatibilidad > 1 (excepto para el maracuyá autoinjertado, 0.85). Asimismo, las plántulas injertadas alcanzaron las condiciones de campo a 15 cm de altura y con cinco hojas entre los 30 a 60 días después de la injertación. La mayoría de los portainjertos evaluados mostraron un efecto en la reducción de la altura de la planta, número de entrenudos y hojas de aproximadamente 35 %, en comparación con el maracuyá amarillo no injertado. Por lo tanto, es necesaria una evaluación integral para establecer y seleccionar cuáles son los portainjertos más promisorios para mitigar esta problemática en el cultivo de maracuyá.

Published: September 2024

El poliestireno expandido (EPS) es un polímero sintético de uso común en diferentes industrias y posee una estabilidad molecular que le permite permanecer inmodificable por cientos de años generando un impacto negativo sobre el medio ambiente. Se ha reportado que larvas de coleópteros de la familia Tenebrionidae pueden biodegradarlo gracias a enzimas producidas por su microbiota intestinal. En esta investigación se caracterizó preliminarmente la microbioma intestinal de larvas de Zophobas morio alimentadas con poliestireno (PS) y avena, empleando metabarcoding, mediante secuenciación Illumina Miseq de la región V3-4 del gen 16s del ARNr. Con los resultados de la secuenciación se analizó la composición taxonómica y la abundancia relativa de las bacterias, de lo cual se obtuvo que el género Spiroplasma fue el más abundante en las dietas de PS y avena, y no se encontraron diferencias en los análisis de diversidad alfa. Sin embargo, se destacó el aumento del género Pseudarthrobacter en el microbioma de larvas alimentadas con poliestireno expandido y miembros de la familia Enterobacteriaceae sin asignación taxonómica a nivel de género. La identificación de microorganismos posiblemente asociados a una dieta de poliestireno es el punto de partida de ensayos de caracterización, aislamiento y biorremediación, para la degradación de este material; estos ensayos, además, pueden extenderse a otro tipo de plásticos.

Authors: González-Valarezo Helmer Moisés , Paredes-Escobar Mayra Liliana , Córdova-Márquez Sandra Elizabeth , Cuenca-Mayorga Fabián Patricio
Published: September 2024

The quest for technological advancements in food products has led to the exploration of unconventional raw materials and innovative formulations. This study investigated the feasibility of incorporating tannia (Xanthosoma sagittifolium) starch as a partial substitute for wheat flour in pasta formulations. Tannia tubers were sourced, and native starch was extracted following a wet method. Four pasta formulations were prepared with varying percentages of tannia starch substitution (5%, 10%, 15%, and 20%), alongside a control sample. Physicochemical analyses applied for moisture content, ash content, acidity, and pH revealed 11.97% moisture, 0.4% ash, 0.007% acidity, and 4.6 pH in tannia starch. The rheological analysis denoted as the parameters in the Mixolab showed alterations in hydration, moisture, and stability with increasing tannia starch substitution. Cooking tests demonstrated a reduction in optimal cooking time with higher levels of tannia starch substitution, attributed to lower gelatinization temperatures of the tannia starch. Weight loss increased with greater substitution of tannia starch, while water absorption varied, showing a non-linear trend. Quality indices reflected changes in dough characteristics and gluten strength with tannia starch substitution. Further optimization of formulations is recommended to balance technological enhancement with pasta quality attributes, paving the way for the development of novel pasta products

La dimensión doméstica oculta en los parques de proximidad. Posibles valores de la tríada naturaleza-parque-hogar
Authors: Jiménez Marina
Published: September 2024

A la naturaleza urbana, sobre todo la de proximidad, hoy se le asigna un papel principal en la salud física y mental. El confort doméstico asociado al hogar tras la Covid-19 también se ha ‘revalorizado’. No hay investigaciones explícitas que incorporen este vector al papel del parque urbano próximo (a la vida cotidiana). Este trabajo trata de avanzar en relaciones y posibles valores en la tríada naturaleza-parque-domesticidad. Para ello, primero hace un doble rastreo bibliográfico, que acerca claves de los beneficios de naturaleza y espacio público a características propias del ‘como en casa’ como apropiación y refugio, y que sitúa el confort y la libertad creativa cotidianos como rasgos de lo doméstico, óptimos para su externalización al parque. Después, gracias a la observación participante, desarrolla una etnografía en cuatro espacios verdes de Valladolid (España) sobre prácticas vinculadas a la ‘domesticidad’, pasando a discutir las connotaciones socioespaciales de las que se alimenta. Finalmente, concluye que estas prácticas domésticas, en coexistencia pacífica con otras, pueden ser síntoma y medio para conseguir la vitalidad perseguida para unos jardines públicos sanadores.

Published: September 2024

El objetivo del presente trabajo es analizar la relación entre os territorios donde prevalece el aumento de las jefaturas de hogar femeninas con las políticas públicas de ordenamiento territorial y aquellas diseñadas para la mitigación y adaptación al cambio climático en Medellín. La metodología usada fue un análisis espacial comparativo entre la localización de amenazas naturales por movimientos en masa e inundaciones del Plan de Ordenamiento Territorial de Medellín (2014) y el riesgo total por cambio climático del Plan de Acción de Medellín 2020-2050 (2021) con el comportamiento de la distribución espacial de las jefaturas femeninas en el periodo intercensal 2005-2018. Los resultados muestran una correlación espacial entre las áreas mayormente expuestas a estas amenazas y a los riesgos en niveles medios y altos con las zonas que recibieron los mayores aumentos porcentuales de las jefaturas de hogar femeninas; a esto se suma que estas áreas históricamente han presentado los indicadores socioeconómicos más vulnerables de la ciudad. Se concluye que las políticas públicas de ordenamiento territorial requieren un enfoque de género integral —político, económico y cultural— en la formulación gestión y financiamiento de las políticas, estrategias, programas y proyectos para afrontar el cambio climático.

To promote the sustainable utilization of Non-Timber Forest Products (NTFPs) in the Legal Reserves of the Cerrado biome, we present a five-step conceptual model that was implemented in a local Settlement in Central Brazil. This study assesses the potential for NTFP harvesting by evaluating tree species with high Importance Values through a comprehensive forest inventory. Three species were selected based on their high importance value and commercial potential: Annona crassiflora (araticum), Caryocar brasiliense (pequi), and Eugenia dysenterica (cagaita). Over a period of twelve months, we monitored the phenophases and fruit production in the study area. Linear regressions were employed to predict fruit productivity by utilizing morphometric characteristics of the trees. Canopy diameter emerged as a significant predictor of productivity for C. brasiliense. Taking into account regional market prices, the estimated gross revenue from fruit production reached RS 4641.00 (U$ 882.00), which could potentially increase by 340 % through simple manufacturing processes. The production period exhibited minimal overlap among the three species, suggesting enhanced utilization of natural resources throughout the year. Nonetheless, the execution of a strategic plan, including an economic feasibility study, is crucial. This research underscores the necessity for further investigations to gain a deeper understanding of the income generated from NTFPs and their role in rural development. Overall, this manuscript significantly contributes to the comprehension of the economic potential of NTFPs in Legal Reserves, offering valuable insights for sustainable planning and management.

El cambio climático está afectando los ecosistemas de alta montaña, provocando alteraciones en la distribución y rango de las especies vegetales con impactos severos en las montañas tropicales. En los Andes peruanos, los cambios en los patrones de temperatura y precipitación, entre otros factores, están afectando a las especies de plantas medicinales utilizadas por las poblaciones rurales. El objetivo de este estudio fue evaluar la flora medicinal y los conocimientos ancestrales asociados a su uso en el contexto del cambio climático en las comunidades del Valle de Salcca (Cusco, Perú). Se llevó a cabo el 2018 - 2019, durante los periodos de lluvias y secas, en trece zonas de muestreo en tres pisos altitudinales. La colecta botánica y la percepción del cambio climático de los pobladores se realizó con el método de la entrevista y se usó las técnicas del camino participativo, el cuestionario semiestructurado y la nota de campo en la observación. Los resultados muestran 183 especies de plantas medicinales agrupadas en  141 géneros y 63 familias. Las familias con más especies utilizadas fueron Asteraceae y Fabaceae. Las especies se agruparon en 14 categorías de dolencias según su uso. Los de mayor uso fueron para aliviar enfermedades del sistema digestivo, del sistema genitourinario y del sistema respiratorio. Principalmente utilizaron las hojas en estado fresco y en forma de infusión. El cambio climático, según la percepción de los pobladores es una realidad que está alterando las propiedades, el crecimiento, comportamiento y distribución de las plantas medicinales del Valle de Salcca.
El origen de los humedales peruanos y su relación con los procesos geológico-ambientales de Sudamérica: Una revisión
Authors: Cerna-Arrue Ariana , Aponte Héctor
Published: September 2024

El Perú cuenta con diversos humedales altamente productivos, distribuidos en sus tres regiones geográficas (costa, sierra y selva). Estos ecosistemas han estado sometidos a diversos eventos hidrometereológicos, climáticos y antrópicos. El análisis de su origen puede servir para identificar cambios en el entorno geomórfico e hidrológico, así como procesos evolutivos biológicos. El presente trabajo tuvo como objetivo sintetizar la información existente sobre los procesos geológico-ambientales que definen el origen de los humedales actuales peruanos. Fruto de una compilación sistemática de la literatura (usando las plataformas Science Direct, Scopus y Scielo) se encontraron 144 artículos relacionados a su historia reciente. El origen de los humedales andinos está direccionado por procesos tectónicos (entre los 16 Ma y 4 Ma), desglaciaciones (después del Último Máximo Glacial), calentamientos (durante el Holoceno) y el afloramiento de aguas subterráneas. Los humedales amazónicos tienen su origen hace 24 Ma a partir de un sistema fluvial, pasando por una fase de mega humedal (Pebas) y adquiriendo su configuración actual (sistema de drenaje) hace 2,5 millones de años. La formación de humedales de la costa está ligada a cuatro procesos: incursiones marinas, eventos meteorológicos como el ENSO (El Niño-Southern Oscillation), actividades antrópicas relacionados a escorrentías y por filtración de aguas subterráneas. Se describe el rol de las actividades humanas en la configuración actual de estos humedales, así como los vacíos de información para la historia de los humedales de cada región.

Se presenta una sinopsis de las especies del género Parablechnum que crecen en Colombia. Se hizo una revisión del material depositado en varios herbarios y de las imágenes disponibles en línea. El género está representado por 18 especies, lo que representa el 45 % de las especies americanas. Estas especies están distribuidas principalmente en la región andina desde los 800 hasta los 3800 m de altitud. Se describen dos especies nuevas, P. givalum y P. imbricatum, y se designan lectotipos para cuatro especies. Se presenta una clave para determinar las especies colombianas y para cada especie se describen sus caracteres diagnósticos.

Los métodos para estimar el tamaño poblacional de las aves urbanas no suelen considerar los efectos que pueden tener diferentes variables ambientales y antrópicas sobre su detectabilidad. El muestreo por distancia es una técnica de baja aplicación en ambientes urbanos, a pesar de que es un método muy efectivo para estimar densidades poblacionales y de bajo costo. En esta investigación analizamos aquellas covariables que pueden influir en la detectabilidad de la tórtola turca Streptopelia decaocto en ambientes antrópicos para estimar sus densidades en el este de España. A través de puntos de conteo realizamos estimaciones en ambientes urbanos, periurbanos y parques. La probabilidad de detección y la densidad fueron estimadas mediante el muestreo por distancia con múltiples covariables y empleamos varios análisis estadísticos para comparar las densidades estimadas. Nuestros resultados muestran que la altura de los edificios influye de manera negativa y la capacidad de los observadores influye positivamente en la detectabilidad de la tórtola turca. La zona urbana concentra la menor densidad tanto de grupos de aves como de individuos en comparación con las otras zonas. El uso del muestreo por distancia es de fácil aplicación en ambientes metropolitanos que ayuda al desarrollo de la ciencia ciudadana.

Digitonthophagus gazella was deliberately introduced to several American countries to remove bovine manure and control hematophagous flies and gastrointestinal parasites. This species, typically found in open habitats, has opportunistic strategies for resource utilization, high reproductive and dispersal rates, and processes large quantities of cattle dung. As a result, it rapidly colonized the lowlands of the American continent, achieving a wide distribution; and being currently catalogued as an invasive exotic species in several tropical and subtropical countries. Based on research completed and samples taken during six years in three ecological environments (forest, intensive silvopastoral systems, and treeless pastures) in the Cesar River valley, northern Colombia, an analysis is proposed to evaluate whether D. gazella behaves as an invasive or a naturalized species. To assess information about its distribution, food preferences, relationship with native species during temporal succession in resource use, ecological functions related to removing dung and soil perturbation, and risks or benefits this species represents to native dung beetle fauna in the valley were weighed. A classification is presented utilizing conventional criteria. According to our analysis, D. gazella could be considered an introduced, naturalized species with minimal impact in the Cesar River valley since it did not enter the forest, did not generate competition through exclusion with native species, prefers bovine dung, completes ecologically important functions for cattle systems, and has economic benefits due to the reduction of agrochemical use. Further research is suggested to corroborate if these results operate nationwide.
