Diversidad y conservación de anfibios y reptiles en un área protegida privada de una región altamente transformada en el sur de Veracruz, México

El establecimiento de Áreas Protegidas Privadas (APPs) es una de las estrategias para la protección de la biodiversidad ante la modificación del hábitat en bosques tropicales; sin embargo, su importancia en conservación ha sido poco evaluada. En este trabajo estimamos la importancia de un APP conocida como Área de Protección y Desarrollo de Ceratozamia (APDC) para la conservación de anfibios y reptiles, en comparación con otras dos APPs (Parque Ecológico Jaguaroundi y el Parque Ecológico Tuzandepetl) en el sur de Veracruz, México. El APDC tiene una extensión de 100 hectáreas: 50 ha de bosque tropical subcaducifolio y 50 ha de pastizal. Los muestreos para este estudio se realizaron entre los años 2015 y 2016, empleando el método de búsqueda libre restringida por tiempo (esfuerzo de muestreo total = 768 horas-persona). En total, en el APDC se registraron 20 especies de anfibios y 35 de reptiles. El 20% de los anfibios y el 32% de reptiles registrados se encuentran en alguna categoría de riesgo de extinción según la Norma Oficial Mexicana NOM-059-SEMARNAT-2010, dos especies de anfibios y una especie de reptil están incluidas en la Lista Roja de la Unión Internacional para la Conservación de la Naturaleza (UICN), mientras que el 12% de los reptiles se encuentran en categoría de vulnerabilidad ambiental alta. El APDC tuvo la mayor riqueza de especies en comparación con las otras dos APPs. Los anfibios tuvieron una composición relativamente similar entre las APPs, mientras que para los reptiles la composición de especies tendió a ser distinta. Nuestros resultados indican que por la riqueza de especies y el número de especies amenazadas de extinción y de especies no evaluadas por la UICN que alberga, el APDC contribuye a la conservación de herpetozoos en una zona altamente transformada del sur de México, en conjunto con las otras dos APPs, donde el Área Natural Protegida bajo régimen gubernamental más cercana (Reserva de la Biosfera Los Tuxtlas) se localiza a 50 km.The establishment of Private Protected Areas (PPAs) is one of the strategies for the protection of biodiversity in face to habitat modification in tropical forests; however, its importance in conservation has been poorly evaluated. In this work we estimate the importance of a PPA, known as Área de Protección y Desarrollo de Ceratozamia (APDC) for the conservation of amphibians and reptiles, compared to two other PPAs (Parque Ecológico Jaguaroundi and Parque Ecológico Tuzandepetl) at southern Veracruz, Mexico. The APDC has an area of 100 hectares: 50 ha of tropical deciduous forest and 50 ha of cattle-pasture. The surveys for this study were carried out between 2015 and 2016, which consisted of free search restricted by time (total sampling effort = 768 person-hours). In total, 20 species of amphibians and 35 species of reptiles were recorded in the APDC. Twenty percent of amphibians and 32% of registered reptiles are in some extinction risk category according to the Norma Oficial Mexicana NOM-059-SEMARNAT-2010, two amphibian species and one reptile species are included in the Red List of the International Union Conservation of Nature (IUCN), while 12% of reptiles are in high category of environmental vulnerability. The APDC has the highest species richness in comparison to the other two PPAs. Amphibians had a relatively similar composition among the PPAs, while for reptiles, species composition tended to be relatively different. Our results indicate that due to the richness of the species, the number of endangered species and species not evaluated by IUCN it harbors, the APDC contributes to the conservation of herpetozoa in a highly transformed area of southern Mexico, together with the two other PPAs, where the closest Protected Natural Area under governmental regime (Los Tuxtlas Biosphere Reserve) is located 50 km away

The implementation of SDG12 in and from higher education institutions: universities as laboratories for generating sustainable cities

IntroductionIt is known that the world is facing and will face significant sustainability challenges. Sustainable Development Goal 12 (SDG12), responsible consumption and production, is one of the most relevant SDGs for building Sustainable Cities. This study is based on the analysis of the implementation of SDG12 in cities, starting from universities as laboratories or first examples of sustainability.MethodsThe study was carried out through a multilevel scale approach. A systematic review of the literature (global scale) of the last 5 years (2018–2022) was conducted. An analysis of the program and the initiatives of a Higher Education Institution (Tecnologico de Monterrey) is presented (local scale). Finally, a survey was applied to Faculty at this University (micro-scale).ResultsThe systematic review indicated that the main themes or aspects addressed in SDG12 by higher education institutions were sustainable food, supply chains, community, infrastructure, technology, policies, energy consumption, the collaborative economy, smart cities, and curricula. The local scale analysis highlighted the Distrito Tec project, 37 institutional initiatives, and 26 courses directly related to SDG12. The survey showed that 8% of Faculty considered SDG12 the most important of the SDGs and stated that this goal is necessary to reduce environmental impacts. As the most significant impact that Universities can have on SDG12, 52% of the Faculty consider that Universities should become living labs in the transition toward sustainable cities, followed by 36% who think it would be better to implement operational facilities.DiscussionThe diverse contributions of the HEIs at the three scales were classified into six categories: culture, mitigation, adaptation, education, research, and outreach. The study indicates that SDG 12 has been achieved by universities in different ways, which overlaps widely with the performance of other SDGs. Results demonstrate that following a multistakeholder approach, international collaborations between HEIs can foster technology-driven multi-disciplinary research projects to consolidate sustainable cities. Building capacity to accelerate the transition of universities into urban living labs will promote climate action among the students who enroll every year

Nonlocality activation in a photonic quantum network

Bell nonlocality refers to correlations between two distant, entangled particles that challenge classical notions of local causality. Beyond its foundational significance, nonlocality is crucial for device-independent technologies like quantum key distribution and randomness generation. Nonlocality quickly deteriorates in the presence of noise, and restoring nonlocal correlations requires additional resources. These often come in the form of many instances of the input state and joint measurements, incurring a significant resource overhead. Here, we experimentally demonstrate that single copies of Bell-local states, incapable of violating any standard Bell inequality, can give rise to nonlocality after being embedded into a quantum network of multiple parties. We subject the initial entangled state to a quantum channel that broadcasts part of the state to two independent receivers and certify the nonlocality in the resulting network by violating a tailored Bell-like inequality. We obtain these results without making any assumptions about the prepared states, the quantum channel, or the validity of quantum theory. Our findings have fundamental implications for nonlocality and enable the practical use of nonlocal correlations in real-world applications, even in scenarios dominated by noise.Comment: Main text and Supplementary Information.

Tropical agroindustrial biowaste revalorization through integrative biorefineries—review part II: pineapple, sugarcane and banana by-products in Costa Rica

Biorefineries are a model for greener production processes, based on the concept of bioeconomy. Instead of targeting first-generation biofuels—that compete with food supply—the focus relies on lignocellulosic material, considering many aspects, such as sustainable fuel production, as well as valorization of waste, as an alternative to the traditional petrochemical approach of goods production. Especially, in tropical countries agricultural activities lead to tremendous amounts of biomass, resulting in waste that has to be dealt with. In the case of Costa Rica, the five major crops cultivated for export are coffee, oil palm, pineapple, sugarcane, and banana. Traditional ways of waste treatment cannot cope with the increasing amount of biomass produced and therefore, bear various challenges often related to increased pollution. This review aims to bring up the recent state of waste treatment but even more, stress potential opportunities of adding value to not used residues; thus, improve sustainability in the agro industrial sector. Part I of the review already highlighted the potential of producing promising bioactive chemical compounds by novel biorefinery concepts from agricultural waste originating from coffee and oil palm cultivation. This second part focuses on the lignocellulose-rich biowaste from pineapple, sugarcane, and banana, showing biorefinery concepts, where fuel and energy production, as well as establishment of novel products and new applications, play an important role. © 2022, The Author(s)
