Resumen en inglés

This study describes the progress of the use of the SES perspective and/or the consideration of users’ participation in the scientific literature that study Mexican fisheries, and their inclusion in the fishery management policy. Since 2001, there have been 57 published investigations on 19 fisheries, mostly from the north Pacific (n= 39), focussed mainly on the governance of SES of benthic fisheries, and from the southern Gulf of Mexico and the Caribbean Sea (n= 14), where co-management and the spiny lobster fishery are the most studied. From 21 fisheries having a fishery management plan (FMP), only seven have an international sustainability standard, while another seven fisheries having a sustainability standard have no FMP. In addition, only nine fisheries, with literature that addresses the SES perspective and/or considers the user’s participation (out of a total of 19), have a FMP and only four of those fisheries have a sustainability standard. This reflects a mismatch between the interests of the academic, fishery, and government sectors. The SES perspective has been stable in the academic research since 2012, and has been implemented for some fisheries through participatory management processes of international fishery standards; however, this perspective needs to be fully included in Mexican fishery management instruments (e.g., FMPs) and its implementation could be a primary goal for Mexican fishery policy.

Resumen en español

Este reciente libro es coeditado por Ecosur y la Editorial de la Universidad Veracruzana. Este trabajo es un esfuerzo por desentrañar las estructuras sensibles de la destrucción planetaria y pensar una revolución que atienda la dimensión afectiva, sensible y sintiente de nuestro Estar en el mundo. Estamos convencidos de que una transformación como la que requiere la crisis civilizatoria de nuestro tiempo requiere de una radical transformación ético-política y estético-poética que reincorpore la potencia del cuerpo, que ponga en primer plano los sentimientos, las emociones, la estética y la empatía.

Resumen en inglés

Human pressure can cause a decrease in the abundance of beach macrofauna, especially supralittoral crustaceans. In studying the life history traits of supralittoral crustaceans, human impact and beach features (e.g. beach slope, grain size, swash width) are often considered separately. Ghost crabs are widely accepted as ecological indicators of beach quality and condition since their abundance decreases at disturbed beaches; moreover, ghost crabs can respond to natural drivers. This study aims to determine factors affecting the density of the ghost crab Ocypode quadrata in the Mexican Caribbean. We studied the spatiotemporal variation of the density of ghost crabs at two urbanized and two reference beaches by counting crab burrows on all beaches during six sampling periods. Our results indicate that physical features of the beach are significantly correlated with burrow density, and burrow density varies substantially between urbanized and reference beaches. The greater variation of burrow density accounted for beach disturbance, followed by beach morphodynamic features. Basedon these results, our study confirms that the ghost crab is a relevant biological indicator species andis useful for guiding beach management criteria in the Mexican Caribbean. Our findings demonstrate that temporal replications must be included when using ghost crabs as ecological indicators.

Resumen en español

El tapir de Baird (Tapirella bairdii) es una especie amenazada en toda su área de distribución, sin embargo, muchos aspectos de su biología y ecología han sido poco estudiados, debido a su comportamiento evasivo y a sus bajas densidades poblacionales. El objetivo de este estudio fue evaluar los patrones de actividad de T. bairdii en relación con las fases lunares en dos sitios con diferente grado de perturbación humana: la Reserva de la Biosfera de Calakmul (RBC) y el Ejido Nuevo Becal (NB). Se monitorearon 20 cuerpos de agua durante18 meses mediante el método de foto-trampeo. Se determinó la tasa de captura (TC) y se registraron las fases lunares correspondientes para ambos sitios. La TC de T. bairdii tapir fue de 0.054 en NB y de 0.029 en la RBC. T. bairdii fue más activo en el periodo nocturno-crepuscular. En general, T.bairdii. mostro una actividad importante durante las fases de oscuridad, pero estas diferencias no fueron significativas estadísticamente. Sin embargo, se encontró una tendencia de los tapires a moverse activamente en las noches y en las horas más obscuras en NB que en RBC. La preferencia aparente por las noches más obscuras en NB podría ser evidencia de la respuesta por parte de los tapires a la perturbación causada por actividades humanas en ese sitio, mostrando un cambio en su comportamiento evitando salir en periodos de abundante luz en sitios perturbados. Sin embargo, se requiere de mayor investigación para corroborar esta posibilidad.

Resumen en inglés

The Baird’s tapir (Tapirella bairdii) is an endangered species throughout its distribution area, however many aspects of its biology and ecology have been poorly studied, due to its evasive behavior and low densities. The goal of this study was to evaluate the activity patterns of T. bairdii, a large ungulate species from the Neotropics, in relation to moon phases in two sites with different degree of human perturbation: the Calakmul Biosphere Reserve (CBR) and the Nuevo Becal (NB) community. We monitored twenty waterbodies in each site for 18 months using camera traps. The photographic capture rate (CR) and the corresponding moon phases for both sites were recorded. The CR of T. bairdii was 0.054 in NB and 0.029 in CBR. T. bairdii was more active at night and dawn-twilight periods. In general, T. bairdii showed major activity during the dark moon phases but the differences with the light phases were not statistically significant. However, we found a trend of tapirs to be more active in dark nights and in the darkest hours in NB than CBR. The apparent preferences for dark nights in NB could be caused by the perturbation caused by human activities at site, which may have influenced the behavior of the tapir that avoid moving out in periods of abundant light in disturbed sites. More research is needed to confirm this finding.

Resumen en inglés

Establishing protected areas constitutes one of the main strategies for the conservation of marine and coastal ecosystems. Increasing risks associated with environmental change along with highly degraded coastal ecosystems encompass complex management challenges for the long-term sustainability of these landscapes. This article aims to explore the role of protected areas in past and ongoing community adaptation to the compounded effects of climatic and anthropogenic change. A literature review of published articles is conducted through systematic queries of the bibliographic database Web of Sciences, and by comparing adaptation and socialecological resilience processes within and out of coastal protected areas. Findings underscore the absence of specific studies that target these topics inside protected areas, highlighting a geographic bias towards research largely carried out in developed countries. Results also indicate the current need for management practices within protected areas to adopt more participatory, comprehensive, and flexible approaches. Protected areas not only promote the conservation and provision of ecosystem services but are also key in building coastal communities' adaptive capacity and resilience in face of future scenarios.

Resumen en inglés

Achieving nature conservation goals require grappling with ‘wicked’ problems. These intractable problems arise from the complexity and dynamism of the social–ecological systems in which they are embedded. To enhance their ability to address these problems, conservation professionals are increasingly looking to the transdisciplines of systems thinking and evaluation, which provide philosophies, theories, methods, tools and approaches that show promise for addressing intractable problems in a variety of other sectors. These transdisciplines come together especially around praxis, i.e., the process by which a theory or idea is enacted, embodied or realized. We present a review and synthesis of the learnings about praxis that have emerged from The Silwood Group, a consortium of conservation professionals, professional evaluators, and complexity and systems thinkers. The Silwood Group believes that for conservation activities to achieve ambitious goals, we should benefit nature without compromising the well-being of people, and that framing a praxis for conservation in the context of social–ecological systems will provide the greatest potential for positive impact. The learnings are presented as four key principles of a ‘praxis for effective conservation’. The four principles are: (1) attend to the whole with humility; (2) engage constructively with the values, cultures, politics, and histories of stakeholders; (3) learn through evaluative, systemic enquiry, and (4) exercise wisdom in judgement and action. We also provide descriptions and references for tools and methods to support such praxis and discuss how the thinking and approaches used by conservation professionals can be transformed to achieve greater effectiveness.

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 inglés

Spatial distribution patterns of the ghost crab Ocypode quadrata were analysed using different approaches at one disturbed and two preserved reflective sandy beaches of the Mexican Caribbean. We used spatial correlation analysis to describe the across-shore distribution of O. quadrata and their patch dynamics by beach and sampling time. In addition, we analysed the across-shore variability of habitat extent of O. quadrata (habitat envelope) and its relation to human disturbance and beach features. The spatial structure of burrow density was consistent through time, showing a bimodal distribution with very low abundance in the mid distribution range and a discrete increment of burrows to landward. Nonetheless, the size of patches varied temporally for the three beaches. Burrow size increased from seaward to landward. The location of the first burrow and the habitat envelope varied among sampling times and beaches. The location of the first burrow is mostly mediated by the swash climate, while the habitat envelope is mainly controlled by the level of human disturbance. Despite the low number of disturbed and control beaches, our results suggest that the habitat envelope could be included in future studies when using ghost crabs as indicators of human disturbance. Polynomial models and variographic analysis proved to be useful tools to describe the across-shore distribution and patch dynamics of the ghost crab.
