Many ecological relationships that are inherently reciprocal are often studied from one perspective only (Agrawal et al. 2007). One example is the interaction between tropical forests and nearctic-neotropical migratory songbirds (hereafter migrants). Several studies have determined that some migrant populations are limited by conditions at their tropical wintering grounds in Central America, South America and the Caribbean (Marra et al. 1998, Mills 2006); however, the ecological role of migrants in these tropical forests is poorly understood.

Resumen: Antecedentes y Objetivos: La avena de mar, Uniola paniculata, se distribuye en el Caribe, los Estados Unidos de América y México. El objetivo de este trabajo es reportar su presencia y registro en el estado de Campeche, México. Métodos: Se colectaron ejemplares de la familia Poaceae creciendo en una duna frontal al suroeste del estado de Campeche, específicamente en la Isla del Carmen. Las colectas fueron procesadas y herborizadas, para su conservación e identificación.Resultado clave: Con la identificación de ejemplares, y después de hacer una revisión de su distribución, se registra por primera vez la presencia de Uniola paniculata (Poaceae) en la Península de Yucatán, representando una contribución al conocimiento florístico de la región y a la flora de México.Conclusiones: Esta especie solo había sido reportada para la costa del Golfo de México, en los estados de Tamaulipas, Veracruz y Tabasco. Este registro adquiere relevancia por el papel ecológico de este pasto en las dunas costeras.Palabras clave: avena de mar, conocimiento florístico, dunas costeras, flora de Campeche.Abstract: Background and Aims: The oat sea grass, Uniola paniculata, is distributed in the Caribbean, the United States of America and Mexico. The aim of this work is to report its occurrence and record in the state of Campeche, Mexico.Methods: Individuals of the family Poaceae were collected growing in a coastal dune in the southwest of the state of Campeche, particularly on the Isla del Carmen. The collections were processed and herborized for their conservation and classification.Key results: With the individuals’ identification and after reviewing its distribution, this is the first report of the presence of Uniola paniculata (Poaceae) on the Yucatan Peninsula, representing a contribution to the floristic knowledge of the region and the flora of Mexico.Conclusions: This species had only been reported from the coast of the Gulf of Mexico in the states of Tamaulipas, Veracruz and Tabasco. This record is relevant because of the ecological role of this oat sea grass in the coastal dunes.Key words: Campeche flora, coast dunes, floristic knowledge, sea oat.

Ecological Functioning

Widely recognized as the largest terrestrial mammal in the Neotropics, the globally endangered, IUCN Red-listed, Baird’s tapir Tapirus bairdii has been in a continual decline due to habitat loss, localized hunting, and their low reproductive rates. Because of its ecological role, the loss of this species is likely to have a cascading effect on a number of species that are important to the ecological functioning of the remaining fragments of tropical forests across Central America. As efforts continue to identify regions where this species still persists throughout its known range, we report here a new record of T. bairdii in the Caribbean lowlands of northeast Costa Rica. Although T. bairdii may have historical existed in the region surrounding the field station, they were believed to be extirpated with only anecdotal reports suggesting their continued existence.

New Strategies

The advance of scientific knowledge in various areas of molecular ecology has allowed the adoption of new strategies, particularly in forest restoration. The fusion of multidisciplinary areas and the implementation of management methodologies in order to get better results in forest restoration are current realities. In order to review the main ideas about the role of molecular techniques in the service of ecology restoration, this paper outlines how forest recovery can benefit from genetic and genomic plant population studies. The next challenges in conservation genetics can be brought by the quest for more efficient forest restorations from the point of view of biodiversity as well as the ecological ynamics as a whole. It is believed that in the coming years we will observe integrated strategies in molecular ecology with specific methodologies for restoration in tropical forests.
