Planning for marine ecosystems management demands spatially explicit information about structural and functional components, in a tradeoff between including the most taxa and keeping it functional. Sentinel, umbrella, and surrogate taxa are strategic for developing indexes that account for other associated species and contribute to a sustainable administration of our seas. Marine turtles feature the former species descriptions, and the knowledge on their ecology contributes to design conservation and restoration strategies in regions they occupy, such as the Gulf of Mexico. Several administrative tools exist to govern marine territories for biodiversity conservation, and assessing how these tools interact with the ecological vulnerability of endangered species is crucial for improving public policies. We assessed the spatial interactions among ecological sensitivity, vulnerability, and the potential impacts on four marine turtle species in the southern Gulf of Mexico and northwestern Caribbean Sea with territorial management tools (natural protected areas, marine priority sites, and ecoregions). A small percentage of the most vulnerable areas is inside natural protected areas, while marine priority sites include a higher percentage. We identified spatial covering gaps that need to be addressed to ensure the conservation and recovery of these endangered species in the Gulf of Mexico and proposed key regions for maximizing territorial conservation.

AbstractIran lies at the southernmost range limit of brown bears globally. Therefore, understanding the habitat associations and patterns of population connectivity for brown bears in Iran is relevant for the species’ conservation. We applied species distribution modeling to predict habitat suitability and connectivity modeling to identify population core areas and corridors. Our results showed that forest density, topographical roughness, NDVI and human footprint were the most influential variables in predicting brown bear distribution. The most crucial core areas and corridor networks for brown bear are concentrated in the Alborz and Zagros Mountains. These two core areas were predicted to be fragmented into a total of fifteen isolated patches if dispersal of brown bear across the landscape is limited to 50,000 cost units, and aggregates into two isolated habitat patches if the species is capable of dispersing 400,000 cost units. We found low overlap between corridors, and core habitats with protected areas, suggesting that the existing protected area network may not be adequate for the conservation of brown bear in Iran. Our results suggest that effective conservation of brown bears in Iran requires protection of both core habitats and the corridors between them, especially outside Iran’s network of protected areas.

Ecological interactions between mites (predatory and phytophagous) and wild plants growing in undisturbed environments play a crucial role to understand their natural settlement, development and dispersion patterns. Pequin chili pepper, Capsicum annuum L. var. glabriusculum, is a low-cost natural resource for local communities living inside Natural Protected Areas (ANP) of Tamaulipas State in Mexico. The aims of this research work were: 1) determine the spatial distribution pattern of predatory and phytophagous mites, 2) determine the spatiotemporal association between predatory and phytophagous mites, and 3) determine the association among different mite species and some phenological stages of Pequin chili pepper. The most abundant phytophagous mites were Tetranychus merganser and Aculops lycpoersici, and the predatory species were Amblyseius similoides, Euseius mesembrinus and Metaseiulus (Metaseiulus) negundinis. Most mite species showed an aggregated distribution pattern according to the plant phenological stages. However, the distribution of mite species throughout time showed different types of aggregation. On the other hand, we found positive associations among A. lycopersici and T. merganser phytophagous mites with A. similoides, E. mesembrinus and M. (M.) negundinis predators mites. The association between plants and mite species were influenced by the phenological stages of Pequin chili pepper. This is an indication of the complexity among trophic-chain interactions that depend largely on the available resources and competition. These two factors serve as foundations for settlement, development and dispersion patterns of certain species.

La Investigación Evaluativa (IE) se originó en el siglo XVII, pero surgió como disciplina formal en la década de 1970. La IE consiste en la aplicación de métodos de las ciencias sociales a la evaluación de actividades humanas específicas. La IE puede ser de diseño experimental, cuasi-experimental o no-experimental y debe reunir 10 puntos básicos entre los que destacan, la planeación y evaluación. En México han existido esfuerzos por evaluar programas de desarrollo social desde 1917 y actualmente esta labor la realiza el Consejo Nacional de Evaluación de la Política Social. A nivel nacional, la evaluación del desempeño para todos los programas públicos es obligatoria. La IE es indispensable en materia de administración de recursos naturales; sin embargo, los trabajos publicados sobre este tópico son escasos. Respecto a las Áreas Marinas Protegidas (AMP), consideradas como instrumento universal de conservación de ecosistemas, la evaluación de los programas para implementarlas se lleva a cabo a nivel internacional mediante diversas metodologías. La evaluación de AMP se aplica con la finalidad de mejorar su gestión y desempeño en cuanto al cumplimiento de metas y objetivos (manejo adaptativo). En México, la evaluación de las AMP está a cargo de la Comisión Nacional de Áreas Naturales Protegidas (CONANP), pero los métodos para realizarla son poco eficientes y se carece de la capacidad técnica para hacer las evaluaciones. Para subsanar esta carencia, se requiere fortalecer la capacidad de evaluación dentro de la administración de las AMP con el apoyo de las organizaciones de la sociedad civil y el sector académico. La adecuada evaluación de las AMP en México permitirá practicar un verdadero manejo adaptativo, cumplimentar los objetivos de implementación y, sobre todo, una clara rendición de cuentas a la sociedad acerca de su eficiencia como instrumento de manejo de recursos naturales. A review on the evaluation research of protected marine areas in Mexico Evaluation Research (ER) has its origins in the XVII century but emerges as a formal discipline in 1970. ER consists on the application of techniques used in social sciences to evaluate specific human activities. The ER design may be experimental, quasi experimental or non-experimental and must contain at least 10 basic points where the planning and evaluation are particularly important. In Mexico there have been efforts to evaluate the programs of social development since 1917. Currently, this task is performed by the National Council for Social Policy Evaluation and the assessment of all social programs is compulsory. Regarding to the administration of natural resources, ER is essential; however, papers published on the subject are scarce. In order to improve the management of the Marine Protected Areas (MPA) and to assess the level on which the goals and objectives has been reached (Adaptive Management) the ER is applied to evaluate the implementation of MPAs using different methodologies. In Mexico, the National Commission of Natural Protected Areas is in charge of the evaluation of the MPAs; however, the methods used have proven little effective and lack of technical capacity. In the MPAs to do such assessments it is necessary to reinforce the evaluation capacity within the administration of MPA supported by civil organizations and academy. Proper assessment of MPAs in Mexico will allow the practice of a true adaptive management, to meet the implementation objectives and, above all, a clear accountability to the society on the effectiveness of MPA as a tool for natural resources management.

In recent years, the popularity of rock-climbing has grown tremendously, setting an increasing pressure on cliff habitats. Climbing may be particularly harmful in the Mediterranean biome due to its appropriate environmental conditions for climbing. A few studies have identified the effect of climbing on plant diversity at a small-scale (namely locally or even just in specific climbing areas). However, no studies exist assessing the potential risk of rock-climbing on a broad-scale (e.g., regional or national). The study aims to identify the priority locations and priority cliff plant species in Spain to focus future study efforts. Spain was selected because it is a plant biodiversity hotspot, with a great diversity of endemic and endangered species, and one of the most popular destinations for climbers. We used a geographic information system-based approach to model the spatial concurrence among Spanish climbing areas (and climbing intensity), natural protected areas (NPAs), and distribution of threatened cliff plants (and their IUCN threat category). We found that 53.5% of climbing areas in Spain are located within a NPA, most of them falling into NPAs of medium protection level. We mapped 151 threatened cliff plants, identifying four medium priority Mediterranean locations and eight priority species in which future research efforts should be focused. High-priority study locations are absent in Spain according to our spatial modeling. For the first time on a national scale, this study identifies areas in which climbing represents a potential threat for cliff habitats and threatened plants. These findings contribute to designing field studies on the effects of rock-climbing on Mediterranean cliffs, laying the groundwork for a sustainable, yet challenging, balance between the protection of these unique habitats and rock-climbing.
