Forests that regrow naturally on abandoned fields are important for restoring biodiversity and ecosystem services, but can they also preserve the distinct regional tree floras? Using the floristic composition of 1215 early successional forests (≤20 years) in 75 human-modified landscapes across the Neotropic realm, we identified 14 distinct floristic groups, with a between-group dissimilarity of 0.97. Floristic groups were associated with location, bioregions, soil pH, temperature seasonality, and water availability. Hence, there is large continental-scale variation in the species composition of early successional forests, which is mainly associated with biogeographic and environmental factors but not with human disturbance indicators. This floristic distinctiveness is partially driven by regionally restricted species belonging to widespread genera. Early secondary forests contribute therefore to restoring and conserving the distinctiveness of bioregions across the Neotropical realm, and forest restoration initiatives should use local species to assure that these distinct floras are maintained.

Automated in-season rice crop mapping using Sentinel time-series data and Google Earth Engine: A case study in climate-risk prone Bangladesh

Mustafa Kamal Timothy Joseph Krupnik (2024, [Artículo])

High-resolution mapping of rice fields is crucial for understanding and managing rice cultivation in countries like Bangladesh, particularly in the face of climate change. Rice is a vital crop, cultivated in small scale farms that contributes significantly to the economy and food security in Bangladesh. Accurate mapping can facilitate improved rice production, the development of sustainable agricultural management policies, and formulation of strategies for adapting to climatic risks. To address the need for timely and accurate rice mapping, we developed a framework specifically designed for the diverse environmental conditions in Bangladesh. We utilized Sentinel-1 and Sentinel-2 time-series data to identify transplantation and peak seasons and employed the multi-Otsu automatic thresholding approach to map rice during the peak season (April–May). We also compared the performance of a random forest (RF) classifier with the multi-Otsu approach using two different data combinations: D1, which utilizes data from the transplantation and peak seasons (D1 RF) and D2, which utilizes data from the transplantation to the harvest seasons (D2 RF). Our results demonstrated that the multi-Otsu approach achieved an overall classification accuracy (OCA) ranging from 61.18% to 94.43% across all crop zones. The D2 RF showed the highest mean OCA (92.15%) among the fourteen crop zones, followed by D1 RF (89.47%) and multi-Otsu (85.27%). Although the multi-Otsu approach had relatively lower OCA, it proved effective in accurately mapping rice areas prior to harvest, eliminating the need for training samples that can be challenging to obtain during the growing season. In-season rice area maps generated through this framework are crucial for timely decision-making regarding adaptive management in response to climatic stresses and forecasting area-wide productivity. The scalability of our framework across space and time makes it particularly suitable for addressing field data scarcity challenges in countries like Bangladesh and offers the potential for future operationalization.

Propagación sexual y asexual de Brosimum alicastrum Swartz en Campeche, México

Sexual and asexual propagation of Brosimum alicastrum Swartz in Campeche, Mexico

Santillán Fernández Alberto Orlando Valentín Santiago Santes Ezequiel Espinosa ZULEMA GUADALUPE HUICAB PECH FRANCISCO ALFONSO LARQUE SAAVEDRA Jaime Bautista-Ortega (2022, [Artículo])

Brosimum alicastrum is a tree species in Mexico with wide potential for animal and human food, which is distributed naturally with no silvicultural management, so there is little information on the propagation methods of the species. The objective of this work was to analyze the scientific research published on B. alicastrum, through literature review to know the techniques that exist on its propagation. In addition, the quality of the seedling obtained by sexual propagation and asexual methods (cuttings, layers and grafts) was evaluated in the nursery, by means of experimental designs. 550 scientific articles on B. alicastrum were found, the disciplines where they were published were: Ecology (44.18%), Botany (13.27%), Forest Sciences (11.27%, of which 2.54% worked propagation in the nursery), Zoology (11.09%), Agriculture (9.64%), Anthropology (5.45%) and others (5.10%). Regarding the seed propagation method, the best seedling quality was associated with low porosity substrates (bush soil) and containers with large diameters (36 cm). In the case of asexual propagation, with the layering method when peat was used as the substrate 90% survival was obtained, and by lateral grafting technique 75% yield was found. Due to the little research that exists on the propagation of the species, it is recommended that the selection of the propagation technique is based on the purpose of the seedling; if it is required to shorten the seed production cycles of B. alicastrum the asexual techniques grafting and layering can be more efficient. © 2022 Universidad Politecnica Salesiana.

Sitios Ramsar de la Bahía de La Paz: Amenazas y estrategias para su conservación

Ramsar Sites of La Paz Bay: Threats and strategies for their conservation

Janette Magalli Murillo Jiménez José Juan Pérez Navarro María Concepción Lora Vilchis MARIA DEL ROCIO MARCIN MEDINA LAURA CARREON PALAU Jorge A. Del Angel_Rodríguez Jose Luis Ortiz Galindo Jesús Echevarría Haro (2022, [Artículo])

"En 2017–2018 la Secretaría de Marina del Gobierno de México (SEMAR) realizó actividades de dragado en la Bahía y Ensenada de La Paz, Baja California Sur. Paralelamente ocurrieron afectaciones severas en el sitio Ramsar “Humedales Mogote-Ensenada de La Paz”. Los dragados y el mal manejo de los residuos generaron preocupación ciudadana por el sitio y los organismos que ahí habitan, lo que se manifestó en protestas tanto mediáticas, como legales ante SEMARNAT por algunas organizaciones de la sociedad civil. Esta situación propició la organización de un Foro-Taller realizado el 3 de octubre de 2019, con el fin de evaluar la problemática de los humedales tanto de la Ensenada como de la Bahía de La Paz, ambos incluidos en la Convención Ramsar. El presente trabajo resume los resultados de este evento y refleja la gran preocupación por los sitios Ramsar, tanto de la sociedad civil, como de las diferentes instancias gubernamentales. Estos resultados se integraron en un documento entregado en febrero de 2020 solo a autoridades de SEMARNAT, CONANP y Congreso del Estado de Baja California Sur, previo a la pandemia. Durante el taller se observó una amplia gama de problemas, originados en gran medida por los habitantes y reforzados por el incumplimiento de los compromisos adquiridos por México ante la Convención Ramsar, patente en la desatención de los sitios Ramsar, en particular de los Humedales Mogote-Ensenada de La Paz, donde no hay una normatividad específica que indique la responsabilidad de la gestión de estos ecosistemas. En contraste, el humedal de Balandra cuenta con protección especial al formar parte de una ANP. La conclusión general más importante del evento fue que sólo una sociedad bien organizada, informada de los servicios ambientales que estos sitios proveen, y consciente de su valor como ecosistemas, podrá defender la sustentabilidad de estos sitios."

"In 2017–2018, the Government of Mexico’s Navy Secretariat (SEMAR) carried out dredging activities in Bahía and Ensenada de La Paz, Baja California Sur. In parallel there were severe impacts on the Ramsar site “Humedales Mogote-Ensenada de La Paz”. The dredging and the mis management of the waste generated citizen concern for the site and their inhabiting organisms. Consequently, there were protests that were prosecuted both in the media and legally before SEMARNAT by some non-governmental organizations (ONGs). On October 3, 2019, indignation led to the organization of a Forum-Workshop to assess the problem of wetlands in Bahía and Ensenada de La Paz, included in the Ramsar Convention. Here we present a summary of the Workshop results that reflect the great concern for Ramsar sites, both from civil society, and from different government entities. The results were integrated into a document delivered in February 2020 only to the authorities of SEMARNAT, CONANP and to the Baja California Sur State Congress, because the advent of the Covid-19 pandemic prevented the delivery to all other institutions involved, identified as responsible in the Workshop. Participants observed a wide range of problems in these sites originated largely by residents and reinforced by non-compliance with commitments acquired by Mexico towards the Ramsar Convention, evident in the neglect of the Ramsar sites, in particular the Mogote-Ensenada de La Paz wetlands, where no specific regulation indicates the responsibility of the management of these ecosystems. In contrast, it was observed that the wetland of Balandra has special protection by being part of a Natural Protected Area (ANP, by its acronym in Spanish). The most important general conclusion of this event was that only a we- ll-organized society, informed of the environmental services that these sites provide, and aware of their value as ecosystems, will be able to defend the sustainability of these sites."
