Antecedentes: El fundo legal (FL) representa una franja de vegetación que rodea a los poblados de la península de Yucatán. Su principal función es el aprovisionamiento de servicios ecosistémicos. Hipótesis: ¿La composición y estructura de la vegetación leñosa del FL difiere al compararse con vegetación madura (VM)? El FL y la VM son similares en cuanto a su riqueza florística pero no en su estructura. Lugar y fechas de estudio: En VM y vegetación del FL de la cabecera municipal de Yaxcabá, Yucatán durante los meses de febrero a julio de 2017. Métodos: Se realizaron 32 unidades de muestreo (UM) en dos tipos de suelo predominante (hollum y kankab); 24 UM se realizaron dentro del FL y 8 UM en VM. En cada UM se registraron a todos los individuos ≥ 2.5 cm de diámetro. La riqueza y diversidad de especies se comparó entre FL y VM mediante la rarefacción para estandarizar el esfuerzo de muestreo y a través de un modelo lineal y una prueba post hoc se definieron las diferencias estructurales entre ambos tipos de vegetación. Resultados: Los resultados revelaron similitud en la riqueza, densidad de árboles y diversidad de especies entre la vegetación de FL y VM. Sin embargo, el área basal fue significativamente menor en el FL. Conclusiones: Las altas similitudes en composición y parte de la estructura de la vegetación del FL con respecto a la VM, es una fuerte evidencia del aprovechamiento sustentable de la vegetación por los pobladores de Yaxcabá.

Resumen en inglés

Background: The fundo legal (FL) represents a strip of vegetation that surrounds many towns in the Yucatan Peninsula. The main function of the FL is the provision of ecosystem services. Hypothesis: Does the composition and structure of the FL vegetation differ from the mature vegetation (VM) of the Yaxcabá municipal seat? / The FL and the VM are similar in terms of their floristic richness but not in their structure. Place and dates of study: In the VM and the vegetation of the FL of the municipal seat of Yaxcabá, Yucatán from February to July 2017. Methods: They were made 32 sampling units (SU) located in the predominant soil types (hollum and kankab); 24 SU were performed within the FL and 8 SU in the VM. In each SU, all individuals > 2.5 cm in diameter were recorded. The richness and diversity of species was compared between FL and VM through rarefaction to standardize the sampling effect and through a linear model and a post hoc test the structural differences between both types of vegetation could be defined. Results: The results revealed similarity in richness, tree density and species diversity between FL vegetation and VM. However, the basal area was significantly lower in FL. Conclusions: The formal differences between the vegetation structure of the FL with respect to VM show us that the sustainable use of FL is possible.

Resumen en inglés

Mayan community forest reserves (MCFR) play an important role in agricultural landscapes in Mexico, as theyprovide forest products and a broad variety of benefits that contribute to improving local people's livelihoods.Nevertheless, academia has generally considered conservation and use of forest resources to be incompatible. Wedescribe the spatial configuration of MCFR, evaluate floristic and structural characteristics of woody vegetation present in selected reserves, and identify social norms that govern use and conservation of MCFR. These reserves largely consist of mature vegetation (80% of total cover); their plant structure is similar to that of the sur-rounding tropical sub-deciduous forest; and they house a large number of endemic species. The MCFR studied contain a total of 146 tree species and cover 11% of the study area, which includes at least 140 villages in thenorth-central part of the Yucatan Peninsula. These reserves are collectively managed and conserved by Mayanpeasants in the interest of the common good. The communities in our study area combine conservation and useof forest resources, and we recommend that in public policy, government agencies and NGOs incorporate MCFRas a model of biological conservation and sustainable natural resource use, taking into account traditionalknowledge and local norms that allow these reserves to function in a sustainable manner.

Resumen en español

Se utilizó un enfoque de métodos mixtos para determinar los movimientos estacionales y regionales del macabí (A. vulpes) en la Bahía de Corozal-Chetumal (CB) y la Costa del Caribe (CC). Se utilizaron entrevistas, cuestionarios, talleres, observación participante y notas de campo para recopilar el conocimiento local sobre tiempo y dirección del movimiento en relación a la estacionalidad, hábitat, alimentación y reproducción. Tambien se utilizaron experimentos de marcado-recaptura para: a) determinar la frecuencia de tallas, abundancia y distancias de migración; b) modelar movimiento y abundancia en asociación a variables bióticas y abióticas; c) modelar movimiento y supervivencia con modelos multi-estado en el programa MARK. Se encontraron tallas significativamente mayores en CC (35 + 4.9 cm) que en CB (media = 28.6 + 4.1 cm), debido a una posible mayor densidad y diversidad de presas en los fondos de pastos marinos de CC. Los movimientos a lo largo de la costa fueron: 1) locales de corta distancia, norte-sur y sur-norte, en ámbitos hogareños (distancias > 3.5 km), asociados con la alimentación y en secas y lluvias (febrero a octubre) durante altas temperaturas, y 2) migraciones de larga distancia (> 10 km) ida y vuela de este-oeste y oeste-este, entre CB y dos sitios de agregación de pre-desove (APD) en el norte de Belice y durante los nortes (noviembre a enero) cuando las temperaturas fueron más bajas. El movimiento resultó en: a) mayor abundancia de tallas pequeñas (<22 cm) en CB durante secas y lluvias y una mayor abundancia de tallas grandes (> 22 cm) en CC durante nortes, y b) menor sobrevivencia en CB que en CC durante nortes debido a la migración. El macabí como una especie sombrilla tiene implicaciones y se recomienda que Belice y México desarrollen una estrategia binacional de conservación y manejo de los hábitats de forrajeo y APD para mantener poblaciones saludables.

Resumen en inglés

Bonefish (Albula vulpes) are an important resource for catch-and-release fishing in the Caribbean Sea. Understanding movements within and between the Caribbean Coast (CC) and Chetumal-Corozal Bay (CB) in Mexico and Belize is crucial for identifying and protecting home ranges, migration routes, pre-spawning and spawning sites. We used a mixed-methods approach to document dynamics of bonefish movement. We collected fishers’ local knowledge (LK) using qualitative methods including workshops, key informant interviews, participant observation and field notes about bonefish seasonal movements. We then used mark-recapture (8816 tagged, 569 recaptured) method to understand bonefish movements by size, location and season. Bonefish were significantly larger in CC than in CB. We documented several seasonal movement patterns. A southward movement within CB during the rainy season was likely driven by salinity changes. This was followed by an eastward long-distance migration during the norths or cold front season between the bay and the Caribbean Sea, likely for spawning, as we document likely spawning readiness, pre-spawning behavior and synchronized to the fore-reef at one of two pre-spawning aggregation sites in a World Heritage Site in the CC of Belize during November and December of 2018. There was then a northward movement during the dry season as a journey back to home ranges. The information presented herein can inform resource management and protected areas planning towards a bi-national conservation and management of bonefish and its habitats.

Resumen en inglés

Although, the involvement of artisanal fishing communities in conservation and management is now commonplace, their participation rarely goes beyond providing local and traditional knowledge to visiting scientists and managers. Communities are often excluded from ongoing monitoring, evaluation, and decision-making, even though these measures can have tremendous impacts on their liveli-hoods. For the past 17 years, we have designed, tested, and implemented a community-based monitoring model in three key marine ecosystems in Mexico: the kelp forests of Pacific Baja California, the rocky reefs of the Gulf of California, and the coral reefs of the Mesoamerican Reef System. This model is intended to engage local fishers in data collection by fulfilling two principal objectives: (1) to achieve science-based conservation and management decisions and (2) to improve liveli-hoods through access to knowledge and temporary employment. To achieve these goals, over 400 artisanal fishers and community members have participated in a nationwide marine reserve program. Of these, 222 fishers, including 30 women, have been trained to conduct an underwater visual census using SCUBA gear, and, to date, over 12,000 transects have been completed. Independent scientists periodically evaluate the training process and standards, and the data contribute to international monitoring efforts. This successful model is now being adopted by both civil society and government for use in different parts of Mexico and neighbouring countries. Empowering community members to collect scientific data creates responsibility, pride, and a deeper understanding of the ecosystem in which they live and work, providing both social and ecological benefits to the community and marine ecosystem.

Resumen en inglés

In several tropical forested areas in which biodiversity conservation and indigenous cultures are interwoven, current conservation policies do not consider how the indigenous communities understand the concept of conservation that is promoted and implemented by conservation programs led by external actors, nor do they consider local traditional practices of resource management. To move towards more inclusive conservation policies that take these two aspects into account, research is required in indigenous settings that can inform policy makers. The present study, carried out in the lowland Maya area of Mexico, aims to investigate local meanings of rainforest conservation and dynamics of land use in two Maya common property holdings or ‘ejidos’ (Noh cah and X-Maben). The study used a Social-Ecological Systems approach comprising: (i) the Maya communities and their local meanings of conservation as a Social Subsystem, assessed through social surveys, and (ii) the rainforest of each studied ejido - which was regarded as an Ecological Subsystem and assessed through satellite images (from 2000 to 2012). In the former, interviewees were asked: “when you hear the phrase ‘conservation of the rainforest’ what do you think is being said?” They were also asked if there were local words in Maya or Spanish that were similar in meaning to the aforementioned phrase. The results relating to the meanings of conservation demonstrate that Maya people, who rely on the rainforest for multiple livelihoods, understand two types of meanings for looking after the rainforest; one promoted by governmental conservation programs, and the other called Kanan K’áax, a Maya phrase that represents their customary or community-based rainforest conservation. Differences between these two models of conservation encompass differences with respect to scale, gender and the Maya people’s own cultural practices.

The results of the local dynamics of land use demonstrate that the landscapes of both study sites are dominated by mature rainforest (ranging from 73.9–82.7%), and are therefore in a good state of conservation, and that their agricultural frontiers have not expanded. Our empirical results are valuable in terms of informing the scientific community about the state of rainforest conservation in the Maya Zone, and providing policy makers (from the Maya area and elsewhere) with information to devise new, more inclusive conservation policies that take full account of the indigenous cultural practices of rainforest management.

Resumen en español

La meliponicultura, practicada por distintas culturas, está constituida de diversos saberes contemporáneos (conocimientos, prácticas y creencias en constante producción y reproducción). El presente estudio aborda el estado actual de la meliponicultura en Tabasco, considerándola como patrimonio biocultural. Se realizaron entrevistas semiestructuradas sobre la relación que tienen las personas con las abejas que cultivan y los saberes contemporáneos que poseen. Se registraron 101 meliponicultores en 15 de los 17 municipios, el 24% pertenece a un grupo indígena. El municipio con mayor número de meliponicultores es el de Tenosique (37), seguido de Tacotalpa (14) y Balancán (11). Se cultivan once especies de meliponinos. Se entrevistaron 81 meliponicultores y se clasificaron en tres tipos de acuerdo a su objetivo: tradicionales (52%), resignificados (42%) y conservacionistas (6%). Lo más común es tener la colmena en troncos (52%), un 32% las tiene en cajas y un 16%, tanto en troncos como en troncos modificados y cajas. El 11% de los meliponicutores sabe dividir sus colmenas. La miel, la cera y la colmena tienen diferentes usos: comestibles, medicinales y religiosos. La relación de los meliponicultores con las abejas es compleja y va más allá de lo utilitario; esta práctica implica saberes contemporáneos sobre la etología, ecología y morfología de las especies de meliponinos. Hay un declive de la meliponicultura en Tabasco por lo que es apremiante tener un mayor conocimiento de ésta y fomentarla entre las nuevas generaciones a partir de un diálogo de saberes.

Resumen en inglés

Meliponiculture, practiced by different cultures, is composed of diverse se contemporary knowledges (knowledge, practices and beliefs that are constantly produced and reproduced). This research investigates the current state of meliponiculture in Tabasco, considering it as a biocultural heritage. Semi-structured interviews were used to know the relationship that people have with the bees that they cultivate and the contemporary knowledge they possess. We registered 101 stingless beekeepers in 15 of the 17 municipalities, of these 24% belongs to an indigenous group. 81 stingless beekeepers were interviewed and classified in three types according to their objective: traditional (52%), resignified (42%) and conservationists (6%). The community with the highest number of stingless beekeepers is Tenosique (37), followed by Tacotalpa (14) and Balancán (11). They cultivate 11 species of stingless bees. The most commom type of beehive is in log hive (52%), 32% have them in boxes of wood and 16% in logs, modified logs and boxes. The 11% of beekeepers know how to divide their beehives. Honey, wax and hive have different uses: food, medicinal, magical-religious and ritual. The relationship between stingless beekeepers with bees is complex and goes beyond the utilitarian realm; this practice includes contemporary knowledges about the ethology, ecology and morphology of the different species of meliponines. There is a decline of meliponiculture in Tabasco so it is urgent to have a greater knowledge of it and to promote it among the new generations through a dialogue of knowledges.

Resumen en inglés

Throughout the process of transformation since 1999 known as the Bolivarian Revolution, harsh class and food system contradictions have unfolded in Venezuela, pitting against one another the forces of the pervasive consumer culture favoring imported foods, the input-intensive Green Revolution agricultural model that represents a state-led push toward food self-sufficiency, and an emerging agroecological paradigm pushed forward by grassroots movements who have seized political openings through the largely supportive policy environment. The Bolivarian University of Venezuela, itself a product of the revolutionary process, founded the Program Degree in Agroecology (PDA) in 2004 to expand agroecological practices and knowledge, based on alternative pedagogical approaches. Over the next decade, over a thousand PDA graduates have come to occupy institutional spaces and productive projects in urban and rural areas, contributing to vertical and horizontal agroecological scaling. PDA graduates and educators play a key role in the growing movement of urban agriculture that confronts the economic crisis. The PDA has created key mediators in the form of human talent for territorializing agroecology and institutionalizing pro-peasant policy in Venezuela. As a political outlier, Venezuela is an important case for studying the strategies for territorializing what we refer to as socially committed, situated agroecology.
